Intro

These days, frequently, a reviewer collaborates with a manufacturer to design earphones with his or her tuning. Such products are generally very much hyped by the reviewers themselves or their fanboy or both. The US$99 Tripowin X HBB Olina (will be known as “Olina” from now) is such a product.

Recently, there have been endless mentions and discussions on this earphone. As the name implies, Olina is a collaboration between Tripowin and HawaiiBadBoy (HBB) of Bad Guy Good Audio Reviews YouTube channel.

The Olina is being promoted as using the same 10mm Carbon Nanotube (CNT) dynamic driver and tuned similarly to another Chi-Fi single dynamic driver classic – Tanchjim Oxygen (will be known as “O2” from now). The O2 retails for US$280, although you can buy one for around US$200 from Drop right now.

Tanchjim O2 is known for its coherent, smooth yet technical sound. Olina, as claimed by many, to be as good as if not better than O2… So, to validate these bold claims, I picked up a loaner unit from a friend.

So, is this “CO2” or “Cloned-O2” is as good as those claims? The O2 is my own personal set. Let’s find out…

DISCLAIMER: The Tripowin X HBB Olina was a loaned set from a friend. I will keep my impression straight-to-the-point and as truthful as possible.

My listening was done with as many sources and platforms as possible for fair results. This includes playback from both desktop and portable setups. The music I use ranges from pop and rock, jazz and classical, as well as EDM and movie OST.

Initial listening was done with an all-stock configuration. I also experimented with third-party accessories and PEQ during subsequent listening tests.

Hits

Harman Target tuning for versatility! Dynamic, punchy and full-bodied bass with just the right touch of sub-bass. Midrange is clean and highlights micro-nuances and textures very well. The vocals are crisp, clear and vivid. Treble extension is excellent with ample amount of air and space. Music instruments such as percussion, trumpet and saxophone come across as clean and pristine.

Stage has good dimensions with pinpoint imaging, good instrument and channel separation. Overall tonality is bright, lavish and contrasty. Technical performance is very good at this price. Smooth and rounded housing allows long listening sessions without discomfort. Fit is surprisingly stable for such chunky earphones.

Misses

Very forward vocals almost to the point of shouty and nasally, dominating almost the entire frequency spectrum. Upper-midrange may sound unnatural due to the harsh and plasticky timbre. Bass isn’t as powerful as some of the other HBB collaborations. Sub-bass rumble not as defined as O2.

Unfortunately, the mid-bass lacks texture and detail despite its slightly bright nature. Because of this, certain instruments like bass and cello may sound a bit hazy and one-dimensional. Despite its very good technical performance, I find it strident and a bit artificial.

You can have very good technical performance and still sound natural at the same time… Fine examples are Acoustune HS1697Ti and Moondrop KATO. The overall presentation of black box, gray housing and gray cable aren’t the most aesthetically-pleasing (to me).

Matching

Due to its forward vocal and bright-sounding nature, Olina is best paired with a laid-back and warm sounding tube DAC/amp, such as the Woo Audio WA7 Fireflies. For portable DAP, the Cayin N3Pro synergies well with Olina.

I would also replace the stock cable to one made of pure OFC copper from any reputable brand (personally I go for Yinyoo). I understand HBB suggested pairing with SpinFit CP-100. Being an eartip connoisseur myself, SpinFit won’t be my first choice. I would go for either Canal Works CW Dual Nozzle or JVC Spiral Dot. Both of these eartips tame upper-midrange harshness and glare.

Suggested PEQ Settings

41Hz, +5.0dB

Low-shelf,330Hz, -1.5dB,

Low-shelf2, 500Hz, -3.0dB

Q=1.805,000Hz, -3.0dB

Q=3.09,500Hz, -4.5.0dB

Q=8.012,700Hz, -6.0dB

Q=8.0Preamp gain: -1.5dB

Conclusion

Now the MOST IMPORTANT question… Is Olina tuned similar to O2? My firm and definite answer is “NO!”…

Then is Olina as good as O2? Again, no! O2 is another league altogether (to me at least).

Then what the hell is Olina good for? If you like very forward and bright vocals, Olina may be your cup of tea. In comparison, O2 has better tonality, overall coherency, finesse and technicalities. Olina just sounds bright, harsh and aggressive. 

Here is a fine example that same graph does not equate to same sound. On paper, both Olina and 02 measure very similarly but actual side-by-side listening proved otherwise.

Appearance-wise, Olina looks drab with the gray-and-gray theme. The name Olina supposed to mean “joy” in Hawaiian native language, unfortunately this presentation doesn’t “spark joy” for me.

There you have it… Another hype train crashed and went up in smoke… Or should I say another bag of air labeled as “CO2” or Cloned-O2.

Testing Parameters and Disclaimer

The following tests of silicone eartips are based on my evaluations and listening observations. All test are conducted in a quiet listening environment. Fit is ensured such that eartips are properly inserted and seated into the ear canal with good seal. I have to elaborate, your experiences may vary.

Associated equipment list: Sources – Luxury & Precision W4, Questyle M15 and Sony WM-A105. IEMs – 7Hz Timeless, 7Hz Salnotes Zero, 7Hz Sonus, Tanchjim Oxygen and Moondrop Blessing 2.

Disclaimer: All scores are subjected to change without notice. I may update or add new scores every few months when I acquire new eartips.

NOTE: I don’t have favorite eartips but if I want neutrality, SpinFits CP-145 is my first pick usually. For IEM tuning, I always use reversed KZ Starline, follow by stock eartips from the manufacturer.

What was Acoustune thinking when they came out these?! 

These eartips are “directional” (meaning you must wear them in a certain way) and a pain in the butt to put on. You need lots of patience and time to get them to sit well inside the ears. Getting the proper “ear seal” is nearly impossible. There is literally zero isolation. The design adopts a WW2 helmet-like umbrella shape with double “wings” design. The wide wing is to face the inner-part of the entrance to the ear canal, and the narrow wing facing out (see attached photos). 

Unfortunately, I couldn’t get them to fit in my ears properly not matter how hard I tried. Although made of soft memory polymer, they become uncomfortable, irritating and warm inside my ears after a while.

Sound-wise, these eartips thin the sound so much that they make your TOTL IEMs sound like 1950s transistor radio. Everything sounds distant, lean and sibilance.

Another addition to the new Acoustune AEX family. To me, these sound the most open and airy among the AEX members. Tonality and note weight are lighter than AEX07, as well as the older AET07. Overall, the AEX70 sounds cleaner and clearer than both AEX07 and AET07.

Midrange: 4
Treble: 3.5
Soundstage: 2.5

An interesting elliptical eartip which fits two ways and can affect sound. The not so interesting part is it projects a smaller soundstage and vocals get thrown backwards. In both fittings, I experienced quite significant treble roll-off and details lost. Isolation is NOT GOOD!

Yes, it is called “anti-allergenic sleeves”. If you can find these at your local earphone stores, GET IT! These sound extremely close to Azla SednaEarFit XELASTEC but at half the cost. If you are not used to the grippiness or tackiness of the XELASTEC, AKG is the best alternative. Vocal is forward with very good dimension and ambience. 3D. Best of all it doesn’t affect bass and treble.

These wide bore eartips bear an uncanny resemblance to JVC Spiral Dot in look but they don’t sound alike. The HSE-A1000 is brighter, more open and livelier. Midrange has more sparkle and life. The bass is cleaner, tighter and more textured. Best of all, they cost only a fraction of the JVC. I am surprised how good these are. What a hidden gem!

Both Baskingshark and Vannak Pech are fans of this eartip. It adds “round-meatiness” (a.k.a smoothness and body) to the music without clouding the low-mids. Vocals can be a tad forward but still very pleasant. I would rank its sonic signatures between SpinFit CP-145 and Final Audio Type E eartips. Similar to SpinFits, it has a pivoting cap design.

Another pricey eartip offering from Azla. Feels just like XELASTEC. Both XELASTEC and Crystal excel in the midrange and vocals. Their most obvious differences are in the upper-mids and mid-bass range where Crystal adds a touch more instrument presence, separation and space. Mid-bass is cleaner and clearer than XELASTEC yet doesn’t sacrifice warmth and body. It is good to note that Crystal does not have the upper-midrange “ringing” that plagues XELASTEC.

Azla SednaEarfit Foamax (Standard)
Bore size: wide bore with Waxguard.
Stem length: regular
Feel: medium density firmness and spongy

Bass: 4.50
Midrange: 5.00
Treble: 4.00
Soundstage: 3.50
Vocal presence: 5.00

I came across the SednaEarfit Foamax ear tips and was intrigued by users who claimed they were a superior alternative to the significantly more expensive Sony EP-NI1000M. If these claims hold true, Azla could have a major success on their hands.

In terms of sound quality, the SednaEarfit Foamax offers a crisper and clearer soundscape compared to the Sony. Vocals are more prominent and detailed, and the treble boasts a touch more vibrancy. However, the bass performance and soundstage are largely comparable between the two.

The SednaEarfit Foamax feels softer and plusher than the Sony, thanks to its slow rebound foam that regains its shape completely within 30 seconds. Additionally, the built-in mesh avoids causing any discomfort to the ear canal, unlike the Comply’s own Waxguard.

So, is the SednaEarfit Foamax better than the Sony EP-NI1000M? While I believe they offer a compelling alternative at a significantly lower price point, I personally favor the Sony’s more balanced sound signature. Nevertheless, considering they cost slightly more than half the price of the Sony, SednaEarfit Foamax is definitely worth considering.

Azla SednaEarfit Max ASMR (Standard)
Bore size: narrow bore with Waxguard, short cap
Stem length: regular
Feel: firm and flexible

Bass: 4.50
Midrange: 4.50
Treble: 3.50
Soundstage: 3.25
Vocal presence: 5.00

This eartip, the narrow bore version of the SednaEarFit Max, offers a distinct variation within the family. Compared to its sibling, SednaEarFit Max ASMR tightens the sound, resulting in a smaller perceived soundstage. However, it compensates with a more precise and focused sonic image. Additionally, it delivers superior tonal density, improved textural clarity, and richer vocals. As the name suggests, vocals are emphasized and brought forward in the mix, creating a sense of intimacy. However, there is a trade-off in the form of reduced treble extension and a lack of high-frequency sparkle. This translates to a smoother and more natural but potentially less detailed listening experience overall.

Azla SednaEarfit ORIGIN for In-Ear Monitor & TWS
Bore size: regular, tapered to a wide opening
Stem length: long
Feel: firm and flexible

Bass: 5.00
Midrange: 4.50
Treble: 3.50
Soundstage: 4.00
Vocal presence: 4.75

The ORIGIN eartips are, without a doubt, the most bass-forward I’ve ever encountered. But fear not, bassheads, because this is a good thing! They deliver a satisfying low-end rumble that’s surprisingly free from bloat and muddiness. While they might not pack the same punchy, dynamic punch as the Penon Audio Liqueur black eartips, the ORIGIN compensates with a smooth, fluid presentation for vocals, offering a truly captivating listening experience. However, there’s a catch. While the lower frequencies are a feast, the upper treble frequencies exhibit a slight roll-off, meaning they lack some sparkle and airiness. So, if you crave razor-sharp highs, these might not be your best bet. Overall, if you’re a bass aficionado who values smooth vocals, the ORIGIN eartips are definitely worth considering. They excel at creating a rich and immersive listening experience, but may not be the ideal choice for those seeking a more analytical or balanced sound signature. Perfect eartips pairing for Simgot IEMs especially with EA1000.

Another highly-requested eartips from the audiophile community. However, just like its TWS sibling, these are not my favorite! First of all, their fitting is awful. It is too short for my ear canal. Second, I am not a fan of having waxguard inside the nozzle. And finally, why people like these are the main reasons for my dislikes. They introduce too much bass and mid-bass boost. The treble clarity and extension are suppressed and restricted. Vocals have a thick nasally undertone and are pushed forward. Overall, these present an average tonality that is surpassed by many cheaper eartips. If you haven’t purchased these, save your money. Azla SednaEarFit (Light) Short is better. It is another déjà vu moment for me with SednaEarfit Max series.

Highly-praised by Singaporean audiophile Reza Emmanuel as his standard reference, I must say this eartip is extremely comfortable, literally fatigue-free for long listening sessions.

Sound is clean, tight and very well-textured. Bass and low-mids are detailed, punchy and dynamic. Midrange is clear with excellent separation. Upper-mids and treble are smooth and extended with good amount of air and spacial cues. Vocal position is ‘just nice” – that is neither too forward nor too laid-back. Soundstage is realistically wide without sounding too spread-out. Similar to SpinFit, this eartip comes with a pivoting umbrella/cap.

Canyon is a German company however these eartips are made in China. Interestingly, I find these eartips very pleasing, especially in staging. The ET400 is laid back yet retains imaging scale and focus very well. Although the packaging says “bass”, the ET400 isn’t bassy or rumbly. I would classify it as balanced with a touch of midrange warmth.

An interesting audiophile’s “sanitary” product from Japan, and made in Japan. How true is the anti-bacteria, anti-microbial and anti-virus properties I don’t know (it comes in a plastic “petri dish”) but I do know these eartips roll-off treble and thicken bass and mid-bass. You lose clarity but gain body and smoothness. Recommended for bright and harsh sounding IEMs.

A slightly more bassy version of Acoustune AET08. The ST35 has solid and punchy bass, full-bodied midrange and good vocal presence. Nonetheless, it has a slightly rolled-off treble. Similar to the AET08, soundstage and stereo imaging are average. Instruments and voices are tad front forward but non-offensive. It has a pivoting umbrella just like SpinFits.

These eartips have an extremely shallow fit due to their noticeably short stem. They produce a very midrange-forward sound with suppressed mid-bass and forward vocals. The soundstage is open and airy. They remind me of Moondrop Spring Tips with a sturdier cap and shorter stem. Vocals can sound sibilant and piercing when matched with bright earphones, so be very careful with your pairings.

If you don’t look closely, this eartip looks almost identical to Radius Deep Mount. It has the Beefeater bearskin shape which is wide on top and narrow at the bottom. Quite a transparent sounding eartip I must say. Sounds brighter than Deep Mount with slightly less bass. Korean Radius Deep Mount? Not suitable piercing or lean sounding IEMs.

It presents clean yet balanced sound signature with a large soundstage, both width and depth, and good imaging. Perfect match for planar IEMs (these are attached permanently to my Timeless and Timeless AE). My only complain is they have an awkward fit and can be uncomfortable for some people. Comes in a plastic storage case with 3 pairs of your chosen size. Good stuff!

Different from EarrBond New Hybrid series, Barreleye eartips use a sturdy silicone core which give an surprisingly good seal without the squishy feel of foam. Similar to the New Hybrid series, sound is laid back. Barreleye Blue has better clarity, instrument separation, treble extension, stage depth and layering than Barreleye Green and New Hybrid.

However due to its emphasis in the upper-midrange and treble regions, Barreleye Blue isn’t suitable for bright, sibilant or harsh sounding earphones. Group member Vannak Pech described the sound as if “when you apply contrast filter to your image…”.

At US$50 for two pairs (mimimum order quantity is 2 pairs), these hybrid eartips are one of the most expensive eartips in my collection. Equally as comfortable as original EarrBond EBT eartips and feels softer than Pentaconn COREIR Brass eartips. Isolation is exceptional. Are they worth US$25 a pair? Frankly, no! Performance is on par with silicone eartips such as Final Type E and Divinus Velvet. However, if you are looking for foam-level isolation with upper-midrange clarity, look no further. The difference between copper and stainless steel is copper eartips sound warmer and fuller. The vocals are more intimate also.

Safety concerns: Since the metal cores are inserted halfway into the nozzle. It may accidentally slipped out and leave inside the ear canal… Let’s say I am paranoid.

EarrBond is softer and more squishy compared to other hybrid eartips, thus more comfortable for long-listening sessions. The moment you put them on, they simply disappear into your ear canals. Furthermore, they isolate well too. Sound-wise these are a bit too laid back for my taste. Also, I could detect some sibilance on a some female vocal tracks. In term of wearing comfort and isolation, this win hands down.

For ￥250 or US$2.50, you’ll get 4 pairs of eartips consist of X-Small, Small, Medium and Large sizes. Sound-wise, it is neutral tonality with emphasis in upper-bass and midrange regions (which adds body) as well as in vocals. I rank these higher than SpinFit CP-145 and on-par with Final Audio Type-E (black) eartips. Everybody should get these eartips if they ever come across it.

I will like to thank Jeremy Phua for bringing this eartips to my attention. Japanese consumer electronics brand Elecom is relatively unknown outside of Asia. But even in Singapore (where I live), Elecom products are uncommon.

Some online rumours claimed that Tanchjim includes this as the stock eartips with some of their IEMs. I have the stock eartips from Tanchjim Tanya. After comparing both, my conclusions are they look “quite” similar but sound different.

Nonetheless, this eartip sounds energetic but balanced overall. My only gripe is that vocals can sound a bit strident and nasally. Not as refined as Acoustune AET07 or SpinFit CP-100.

Stem length: short

Bass: 3.75

Treble: 4.25
Soundstage: 4.50
Vocal presence: 4.75

These eartips are so soft and smooth, they feel like luxury! The texture is similar to Divinus Velvet eartips. They suppress the mid-bass and bring the midrange and upper midrange forward, making them perfect for warm or muddy sounding IEMs. The soundstage is wide, deep, and tall, giving a sense of space around every instrument and artist.

My only gripe is that the silicone material feels thin, which affects the ear seal and isolation.

Compared to Azla SednaEarFit (Light) Short eartips, the Azlas have better low-end punch, vocal clarity, and airiness. The Baroque eartips sound smoother overall.

Compared to Moondrop Spring Tips eartips, the Spring Tips have more vocal presence and are clearer and cleaner. However, the Baroque eartips sound more organic, have better tonal weight, and are less fatiguing.

Overall, the Baroque is a great addition to any eartip collection.

Just like its sibling the EP00, these eartips tame sibilance and peaky treble exceptionally well. However, it DOESN’T roll-off highs and kills the air and ambience like some other foam tips.

Vastly similar to Azla SednaEarFit XELASTEC, Fender SureSeal offers a more laid-back presentation with balanced sound. Mid-bass is a tad fuller. Soundstage slightly wider than XELASTEC but imaging is less precise. SureSeal does not suffer from the upper-midrange ring that plagues XELASTEC especially with DD-based earphones. Expect dust-magnet. All thermoplastic elastomer eartips require regular washing and sanitizing to prevent ears infection.

Is this US$7 per pair Chinese-made TPE eartip comparable to Azla SednaEarFits XELASTEC and Fender SureSeal? I am sorry to say the H270 eartip doesn’t feel and wear like a TPE eartip. Thus, I do suspect it isn’t made of TPE at all. Probably made of silicone at best. Nonetheless, H270 is a very lively-sounding eartip. Bass is quite punchy.

Sub-bass rumble is good. Midrange is crisp and clear. Treble extension is very good. Soundstage and imaging are good. If you can overlook the fact that this isn’t made of TPE like they claimed, this is a pretty decent eartip. In terms of sound, it is closer to SureSeal than XELASTEC. Both eartips have accentuated upper-mids and treble.

This Chinese Filter H370 does remind me a bit of ADV Eartune Fidelity U Elliptical eartip but performs far worse… Yup, in my encyclopedia of eartips this one is pretty bad. First thing you will notice is how boomy and wooly the bass is. It is so bad that it bleeds into the mids. Upper treble is rolled-off, thus lacking a sense of space and openness. All-in-all, the H370 is a dark-sounding eartip with poor technicalities. Comfort-wise is quite good though. What a pity!

Quite the opposite of regular Final Type E eartips sonic-wise, These tips intensify upper-mids and treble, which unfortunately, introduces sibilance to female vocals and makes cymbals sound tinny.

Neutral tonality with very “bouncy” bass. Midrange is smooth and laid-back. Treble is crisp and sparkly however its presence is not emphasized (which is a good thing in general). Soundstage is very open and airy. One of the better eartips I have tested in 2022. Yes, the FiiO HS18 can rival some of the pricier offerings from SpinFit, Acoustune and Azla.

However, the true strength of these TPE eartips lies in their exceptional clarity, resolution, and ability to create a wide soundstage.

They avoid harshness or excessive emphasis on any particular frequency range. These eartips prioritize clarity, ensuring that vocals and instruments are well-defined and easy to distinguish within the mix. The graphene-infused version of the IE45 eartips further enhances the smoothness and reduces listener fatigue. This is achieved through the unique properties of graphene, a material known for its excellent damping properties. The IE45 eartips offer good value for the price. They provide a significant improvement in sound quality for both TWS earbuds and IEMs, without breaking the bank.

While primarily advertised for TWS earbuds, the Infiter IE45Pro eartips can also be used with traditional IEMs. They offer a smooth and balanced sound signature that prioritizes clarity. The Clear version delivers a smooth and non-fatiguing sound profile. However, certain listeners might find that vocals, especially female vocals, can take on a slightly nasal quality. The treble range lacks a bit of sparkle and vibrancy, which can make the sound feel a bit dull or veiled. The soundstage feels somewhat compressed, meaning the instruments may not seem as spacious or separated as with other eartips. Despite the mentioned limitations, IE45Pro Clear offers good value for the price. They provide a decent overall sound experience.

Although these are stated for TWS, they can be used on normal IEMs but with a caveat. This eartip is a fine example of why TWS eartips aren’t so appealing for high-fidelity use. Because of their short stem, many TWS eartips have the tendency to push vocals and upper midrange too forward, making them shouty. Sub-bass, bass and mid-bass take a back seat. Good match for muddy-sounding earphones. Do take note that TPE eartips are dust and dirt magnet. They will deform and lose its shape over time.

A clearer version of Azla SednaEarFit XELASTEC. You’ll get 70% of XELASTEC performance at a fraction of the cost. Is it worth a try? Sure… But take note these are TPE eartips (just like XELASTEC) thus they are dust and dirt magnet. They will deform and lose its shape over time. Finishing-wise not as beautiful and smooth as Azla’s. Great value for money if you don’t want to pay the XELASTEC price.

These eartips are constructed from very thin and soft silicone and unfortunately these contribute to a poor fit. They struggle to stay securely in place and are prone to flipping over during use, compromising both comfort and sound quality. The thin material significantly impacts the sound signature. The overall sound comes across as bright and lacking in body. Bass frequencies are noticeably suppressed, resulting in a weak and underwhelming low-end experience. The lack of “punch” and “noteweight” refers to the absence of impact and definition in the bass notes, leaving the sound overall thin and hollow. Not recommended.

These eartips are identical to the INfiter W38 model but come in a light blue color. While constructed from soft, thin silicone for comfort, this material unfortunately contributes to a poor fit in the ear. They struggle to stay secure and tend to flip out during use, negatively impacting both comfort and sound quality. The thinness of the material also significantly impacts the sound signature. The overall sound becomes bright and lacks body, with noticeably suppressed bass frequencies. Overall, due to the poor fit and compromised sound quality, these eartips are not recommended.

An incredibly unique eartip that resembles a whiskey barrel with the entire stem fully concealed within the reversed cap, which forms a dome. It is extremely comfortable, isolates and seals very well. Because sound is reflected into the dome, it has an echo (reverb) effect. This presents a wide soundstage with particularly good height and depth. Unfortunately, this echo effect causes vocals, female voices especially, to sound nasally and wheezy. As if the singer is singing with his or her nose pinched. Without a doubt, the iReep 01 is the most unusual eartip in my collection.

Jomo Audio ONYX Double Flanges Premium Silicone Eartips (For IEMs)

Soundstage: 5.00

Double-flange eartips with wide bores are a rarity. The Acoustune AET06 series is another example of such eartips that I’ve reviewed. In comparison, the ONYX double-flange eartips deliver a brighter, clearer, and more open sound signature. However, they also significantly reduce low and mid-bass frequencies, sacrificing dynamics in the process. While this is ideal for those seeking to reduce bass bloat or muddiness, it makes them less suitable for bright or lean-sounding IEMs. The thin flange material tends to curl upwards when removed from the ears.

The most unique and unusual eartips in my entire collection. From the Land of the Rising Sun, LIZER LAB eartips feature a patented metal phase-plug which promise to “reposition” your music to sound as if music is coming from the front, rather than from inside and above your head. LIZER LAB claimed their eartips to give the listener an “out-of-head localization” concert and live performance experience. Is this snake oil or real? Does it works? My conclusion is it depends. The effects on some earphones are prominent while others are not as outstanding.

Nonetheless, vocal is extremely clean. Bass is slightly recessed (compared to conventional silicone eartips such has Final Audio Type E), nonetheless still sounds full and weighty. Treble extension is good. Soundstage and stereo imaging are exceptional. Pairs well with neutral-warm sounding earphones.

LIZER LAB JIJUFIN eartips don’t come cheap. A pair will set you back 3,880 Japanese Yen or around US$28. Nonetheless, it gives the listener a unique experience and definitely a conversation piece among audiophile friends.

These originally come stock with Moondrop KATO. First impression is how suppressed the bass and mid-bass are, which thins the overall note-weight and body. Midrange is textured with good details. Vocal is forward with very good presence.

Treble has good sparkle and crisp, however it lacks that last bit of extension and airiness. Great match for earphones with too much mid-bass or has bleeding mid-bass. The caps are too soft in my opinion. They flap over every time I remove them from my ears, which is very annoying.

Pentaconn COREIR Nickel-plated Brass core Eartip (PTM01)

Stem length: long
Feel: firm, sturdy and gripy

Bass: 3.50
Midrange: 5.00
Treble: 5.00
Soundstage: 3.50
Vocal presence: 4.75

At 3,850 Japanese Yen (US$35) for 2 pairs of eartips, the COREIR is currently the second most expensive eartip in my collection right now (most expensive is the Sony EP-NI1000M). However, is it worth the high-price it is asking for? Personally, I say “no” and here are the reasons… 

I find the COREIR eartip only suitable for certain types of IEM, particularly those with a very warm, very fully low-end and a recessed midrange, such as the Acoustune HS1650.

When used on Harman-tuned IEMs such as the Tanchjim Oxygen, Salnotes Zero or TangZu Wan’er, the COREIR thins midbass, pushes the midrange and vocals a tad too forward to my liking. Also, occasionally it can sound shouty and nasally especially on female vocal tracks. 

Because of its forward presentation, I find the soundstage a bit narrow. Air and separation around the instruments isn’t as spacious  or as defined as I expected.

Comfort-wise, COREIR falls in between Moondrop Spring Tips and Azla SednaEarFit XELASTEC, although not as grippy as the latter. However, because of the brass core, having the correct fit is crucial… More than ordinary silicone eartips in fact. Just like many TPE eartips, these can heat up the inner-ear and cause discomfort. 

I was disappointed to be honest… But some of you may find good use with the COREIR. I know quite a few reviewers like it.

Thank you Jeremy Phua for bringing this eartips to my attention. I didn’t notice Radius came out with a clear version of their ever popular Deep Mount until he mentioned it.

These sound a smidgen cleaner and clearer than the regular black version. Soundstage is a bit better. I could hear more air and separations around the vocals and every instruments.

Regardless of colours, Radius Deep Mount still remain as one of the most transparent eartips I have tested.

These eartips from Raptgo come with pivoting cap design similar to that in SpinFit. They add “round-meatiness” (a.k.a smoothness and body) to the music without clouding the lower-midrange. The vocals are forward but still very pleasant. I would rank its sonic signatures between SpinFit CP-145 and Final Audio Type E eartips. Same as Audiosense S400.

This eartip has rhombus patterns stamped around the cap (or umbrella) thus the name “diamond” Earfit. This eartip bears some resemblance to Moondrop Spring Tip, however Diamond Earfit is a bit shorter height-wise. Vocal is forward with very good presence. Midrange and treble feels more open and livelier than Spring Tips. Just like Spring Tips, Diamond Earfit thins bass and mid-bass, reduces note-weight. Skip if you prefer bassier eartip.

Very pricey eartips from Softears. Appearance and texture feel just like SednaEarfit XELASTEC, although it says “Liquid Silicone”. Frankly, I have no clue what liquid silicone is other than those used in aesthetics surgery.

However, I find these eartips sound very much cleaner, clearer and airier than both XELASTEC and Crystal. Midrange and vocal presentation are outstanding. Softears Liquid Silicone does not have the upper-midrange “ringing” that plagues the original XELASTEC eartips. Unfortunately, these eartips attracts dirt and dust just like XELASTEC, so clean them regularly if you decide to try.

This is the most expensive eartips in my collection as of October 2021. These tips retail for US$20 A PAIR! Yes, you hear that right… Two Hamiltons for a pair of eartips!

Deemed to be a replacement for Sony Triple Comfort (EP-TC50), these are eartips with an attitude. They sound like silicone but seal and isolate like a good pair of foam tips. Extremely comfortable and stable fit.

Are they better than XELASTEC? All I can say is both are very different. If you are always a “foam person”, the EP-NI1000 sounds more lively and open than, say, Comply or Dekoni.

Heard from a friend that these eartips don’t last long, so it is better to keep them dry and away from heat. Purchased from Amazon, Japan

These pumpkin-shaped eartips dramatically reduce bass and sub-bass frequencies. Their emphasis on upper-midrange and treble frequencies is the primary selling point.

Slight improvement over the original CP-100 especially in the midrange and upper-midrange. However, I feel the top-end is less airy than CP-100. Bass also lacks a bit of punch and dynamics. The “plus” addendum probably comes from the better portrayal of the human voice. True enough, vocals sound slightly more forward and crispier.

Imaging, focusing, instrument and vocal separation definitely improved over its predecessor. Personally, CP-145 is still my most favourite SpinFit.

These eartips are originally meant for TWS wireless earpieces but a friend of mine suggested they are very good at cutting down bass and midbass. Indeed, these are the “Diffuse Field Target-equivalent” of eartips. They clean up the bass.

Reduces mid-bass bloat or muddiness. Upper-midrange is sparkly and treble extension is one of the best I have heard among universal eartips. Vocal is forward with good clarity. NOTE: SpinFit CP-350 has a very shallow fit. Make sure the earphone nozzle length is at least 5mm in order to fit securely.

SpinFit OMNI is the direct successor to the CP-360, with a longer nozzle stem and the distinction of being the first SpinFit product to offer “in-between” sizes, which are common among eartip brands such as JVC Spiral Dot and Azla SednaEarFit.

Compared to the CP-360, the OMNI delivers a thumpier bass response with heavier note weight, forward vocals with good clarity, and treble extension that is slightly less pronounced.

Compared to the W1, the OMNI has a shallower fit and does not provide as good of an ear seal. The low end of the W1 is also more substantial. However, the OMNI offers better vocal clarity, cleaner and crispier highs, and a slightly deeper soundstage.

TAKE NOTE: OMNI will not fit nozzle diameter larger than 5.5mm.

The SpinFit W1 is probably the most anticipated silicone eartip release from the Taiwanese company in recent years, and they certainly deliver. If you like Azla SednaEarFit XELASTEC but dislike its “dust magnet” and tacky properties, SpinFit has answered your prayers with the W1. A hybrid between XELASTEC and Moondrop Spring Tips, SpinFit W1 gives superb clarity, improves soundstage and stereo imaging and cleans up bass and mid-bass. However, I find it unsuitable for bright or harsh-sounding earphones. May exaggerates metallic timbre if and when implemented incorrectly.

… Marketing aside, the T300T (Treble Enhancing) eartip does pushes some high frequency through but it causes the entire bass spectrum and low-mids to “muddle up”, resulting in a loss of texture and low-end details. Does not go well with “thick-sounding” IEMs but good match for leaner-sounding ones BUT be very careful as it might brighten sound too much.

Tang Sancai (唐三彩), known as “Tang Dynasty three-color ware,” refers to a type of glazed ceramic pottery that originated in China during the Tang Dynasty (618-907 AD). The term “Sancai” (三彩) translates to “three colors” in Chinese, which refers to the typical color palette used in this type of pottery. Characterized by its distinctive tricolor glaze, Tang Sancai pottery consists of a combination of yellow, green, blue, and white colors, which explains why these eartips come in yellow (Small), green (Medium), and blue (Large).

These eartips are upper midrange forward with a sense of clarity and space, without sacrificing tonal weight. I prefer this to Tang Sancai balanced eartips. Compared to my reference – the SpinFit CP-145, Tang Sancai wide bore sounds cleaner, clearer and has more texture. Treble extension is much better, providing more space around the instruments.

Compared to the crowd favorite – TRI Clarion, Tang Sancai wide bore sounds less open and not as crisp. Soundstage is a tinge narrower as well. However, it has a heavier note weight than Clarion.

The final comparison is with Moondrop Spring Tips. Here is where both eartips share more similarities. Both eartips are upper-mid forward but Tang Sancai wide bore sounds a tad smoother and less sibilant. It also seals better in my ears but fit is subjective.

Do take note that my audiophile buddy broke one of his Tang Sancai wide bore eartips while trying them the first time. Be very careful when swapping tips.

Characterized by its distinctive tricolor glaze, Tang Sancai pottery consists of a combination of yellow, green, blue, and white colors, which explains why these eartips come in yellow (Small), green (Medium), and blue (Large).

These eartips are vocal forward, full-bodied, and bass-heavy, with an average soundstage projection and a slight top-end congestion. Compared to my usual reference, the SpinFit CP-145, Tang Sancai sounds bassier, more robust, and fuller. Vocals are pushed forward with a bit of nasal undertone, especially on husky female vocals, such as Patricia Barber. Treble extension is much better on the CP-145, providing more space for instruments to breathe.

When compared to Acoustune AET07 and its 07 variants, both eartips become more similar. However, to my ears, AET07 sounds cleaner and clearer. On the other hand, Tang Sancai sounds bolder, with thumpier bass and smoother overall sound.

The last comparison is with Final Audio Type-E. To me, Final Type-E is like a glass of smooth, rich, and creamy oak-aged whiskey. Tang Sancai’s full-bodied presentation can’t match Type-E’s. However, Tang Sancai excels in vocal projection, has slightly better treble extension, and delivers a snappier mid-bass thump. In terms of soundstage, Final Type-E is better but not by much.

Treble: 5.00
Soundstage: 4.75
Vocal presence: 5.00

These latex eartips remind me of FEAULLE H570 latex eartips but cost a fraction less and come in 3 size-pairs per box. Overall tonality is bright and lively. Bass is girthier than H570 with a good thump. Vocals are sibilant but give particularly good enunciation. Stage and imaging are quite good. Resolves nuances very well. Fit and comfort are good. These don’t feel sticky or attract dust like Azla SednaEarFit XELASTEC.

Zeo’s Render hybrid eartips offer a compelling combination of comfort and exceptional isolation, surpassing the softness of Symbio W tips. Their bass performance takes center stage, delivering a punchy and satisfying low-end without the mid-bass bloat common in many foam eartips. In terms of sound signature, they closely resemble the very expensive Sony EP-N1000M, albeit with a slight compromise in upper-midrange clarity. Compared to Zeo’s other favorite, the Dekoni Bulletz foam tips, the Render eartips offer a significant boost in clarity, vocal presence, and bass impact.

My impressions are purely based on the “best” set of audio analyzer I own, which is my pair of ears. Before I dive into the US$290 TRI TK-2, a bit of background story. I knew KB EAR /TRI Audio was planning a dongle DAC/Amp device back in Spring 2020. That time their idea was very vague but their owner did ask my opinion on a possible dongle DAC/Amp solution.

At that time, I wasn’t too keen on their proposal since most dongle DACs I have tried are either quite weak or sounded mediocre. The idea of sharing battery power with the source (the phone) is unappealing to me. I told him I will explore his plans further but I didn’t actually do so… At least not until this year when the donglemadness movement exploded.

Few months ago, I saw a series of photos on Weibo showing KB EAR show booth at an audio event in Mainland China. On the table was a portable device with a TRI logo on it. I knew immediately that was it! That’s the DAC/Amp device which KB EAR had been planning all this time.

Today we know this device turned out to be a collaboration between TRI Audio and KAEI. But who is KAEI? This brand is relatively unknown to those of us outside of Mainland China. Also known as 小林KAEI, they started business producing DIY amps before moving to portable DAPs. Today, the company produces a TOTL iOS-based audiophile digital audio player called DAP-3.

Just imagine a souped-up version of iPod with dual ESS Sabre ES9038Pro DACs and a powerful amp section… That’s how I would describe it. This is the first collaboration between the two brands to bring new variety to the already saturated DAC/Amp market. The innards of TRI TK-2 are largely based on the now discontinued KAEI HP-100.Let’s take a look if the TK-2 can live up to the hype to become one of the mainstream products like the Chord Mojo or the iFi Hip-DAC.

DISCLAIMER: The TRI TK-2 was sent to me “partially” free-of-charge (I paid for the FedEx International Priority shipping) as a review unit; however, this won’t affect my overall impressions.

HITS 

Neutral and balance sound signature with a hint of warmth. Pleasant and linear tuning that is neither too harsh nor too smooth. A wide dynamic range that is both accurate and coherent. Good note weight that is engaging and musical. Great extension at both ends of the frequency spectrum. Transients and attacks are fast with good energy and control that is able to handle even the most complex and demanding music tracks. Textured, open and weighty bass notes. Good midrange presence that is neither forward or recess. There is a hint of softness in the midrange texture and quality, giving each note a refined, luscious and sophisticated presentation.

Nonetheless, the sense of clarity in macro and micro details are still very much preserved. Vocal is positioned at the right depth, which is both inviting and pleasing to listen for hours. Treble is neither bright, grainy nor sibilant. Top-end is open, airy, slightly reverberated that really helps to portray a sense of space. As a result, soundstage has good dimensions in both height and depth.

Placement has a reliable distinction between each and every instrument and singer with ambient details such as echoes and sound reverbs, allowing them to excel and shine. Imaging and layering capabilities are exceptional as well. The TK-2 has a sustaining transients and decay that gives a natural and clean timbre to instruments such as acoustic guitar and violin.

Equally-distributed power of 1,250mW@32Ω to all 3.5mm single-ended, 4.4mm and 2.5mm balanced outputs! (a rarity in budget amps) Class AB amplifier able to churn out lots of clean power with minimum distortion.

When the volume knob turns past 60% or at around 2 o’clock, that is where the magic begins. TK-2 emits a soft “click” and kicks into Turbo mode or high gain. In Turbo mode, TK-2 becomes a Class A amplifier that is able to drive planar headphones such as HifiMan Sundara. You can hear the differences not just in volume gain but the richness in tonality immediately.

Supports Line Out (LO) function. Supports both USB Type-C PD (Power Delivery) and QC3.0 fast charging. Recessed volume knob to prevent accidental movement. No low-volume channel imbalance (on my unit), unlike some iFi products. The L-shaped USB Type-C data cable and Apple Lightning adapter are very thoughtful inclusion. Unlike many DAC/Amps today, TK-2 radiates very little heat even in Turbo Mode (Class A). It feels slightly warm to the touch even with more than 2 hours of continuous usage driving the 300Ω Sennheiser HD600 headphone.

MISSES

No MQA support…. (Frankly I don’t care about the format). Look and feel “chonky” due to its 24mm (1-inch) thickness, which makes it less portable than some DAPs or even a phone with dongle. The silver finishing a fingerprint magnet according to feedback (I have the black version).

No Bluetooth or Line In function. No battery power indicator. No bass boost or tonal selection. Clean but not ultra-clean noise floor with sensitive IEMs such as Campfire Andromeda. Average battery life lasted 8 hours powering just IEMs. Volume knob feels loose and sensitive to the slightest touch; just be careful.

Sound-wise, sub-bass doesn’t go as deep as some other portable amps such as Chord Mojo. Treble can sound a tad bit bright on some tracks. Armed with dual ESS Sabre ES9038Q2M DACs, I expected the soundstage, imaging and layering to be even better but hey, I am just nitpicking here. No dedicated phone app to tweak DAC settings and EQ.

Is this thing firmware-upgradeable? (there is no information from KB EAR) To be honest, it is kind of pricey at US$290 when there are much lower-priced DAC/Amp with better features and future-proof firmware support.

CONCLUSION 

The TRI TK-2 is very hard to dislike. It sounds impressively musical, natural, smooth and pleasing to the ears. As a neutral source, TK-2 is able to pair well with any transducer and is ideal for both testing and evaluation. It has more than enough power capable of driving just about every load; from IEMs to headphones.

Technicalities are stellar for the price especially in terms of tonality, transient, dynamics, resolution, soundstage, imaging, instrument separation and layering. However, lack of useful features such as dedicated app support, MQA support, aptX-HD Bluetooth and Line In function, average battery life and questionable firmware upgradeability can be a deal-breaker to some folks, especially when compared to the competitors at similar or lower price range. Nevertheless, TRI Audio and KAEI have done a fantastic job producing this desktop-caliber powerhouse.

Nice “TRI” guys!

The post TRI TK-2 DAC/Amp Review– NICE “TRI”! appeared first on Music For The Masses.

So, since I have no words to describe how good TRI Meteor is, let me start this impression by “bashing” some its flaws… And don’t worry, there aren’t many. But first, let me introduce the US$109 TRI Meteor. This is the second budget hybrid in-ear monitor after the US$60 TRI I4. And no, Meteor isn’t a successor to I4. Both have very different sound signatures.

Meteor’s sound signature is in fact closer to that of the US$130 TRI Starsea, but again with some differences. Therefore, to me, Meteor is a completely independent product from the rest of the TRI lineup. Both Meteor and Starsea share some similarities such as the resin shell, hybrid configuration and balanced tuning. Starsea has tuning switches which allow users select their preferred sound profile.

Nonetheless Starsea is neither for bassheads nor trebleheads. Meteor is very similar in this aspect.Enough said. Let’s take a look at the TRI Meteor…

DISCLAIMER: The TRI Meteor was sent to me free-of-charge by KB EAR as a review unit; however, this won’t affect my overall impressions.

As mentioned above, I shall begin with some of its shortfalls… However, let me highlight that I measured the TRI Meteor three times using two multimeters (one of them is an industrial-grade Fluke meter).

The measured impedance is 42 ohms, NOT 12 ohms as stated in TRI’s specifications. This means that you cannot use a phone to power the Meteor and expect it to sound good. You will need a decent, DAP or a DAC/Amp combination.

MISSES: Harman-tuning is not for everyone… Dramatic and drastic 20dB roll-off after 9KHz literally deprives and robs the Meteor of air, presence and sparkle. It suffocates wind instruments, dulls brass and percussion instruments.

Sub-bass slightly recessed and lacks thump. Bass and mid-bass can sound a bit matte and dry. The lack of absolute crisp and crystal-clarity, together with feathered (not blurry) edges of sonic imagery, layering and instrument separations, lower the overall resolution and definition.

Soundstage is wide but lacks height presenting a small room feel. The cardboardy imaging and compressed staging maybe a deal-breaker to some folks. Slight presence of BA timbre may render vocals and certain instruments to sound unnatural and plasticky.

Unimpressive stock cable bears uncanny resemblance to the US$8 Yinyoo 8-core pure copper cable. The measured 42 ohms means you need a device with ample amping power to sound good.

HITS: U-shaped, Harman-tuning for the win! Balance, lavished, relaxed and silky-smooth tone across the entire frequency spectrum. Full bodied, textured and well-controlled bass, with just the right touch of sub-bass (when properly amp-driven) that is not overpowering.

The beryllium-coated dynamic drivers are relatively fast, thus very responsive to busy tracks without any congestion and muddiness. The mildly-lifted mid-bass response has a good slam and oomph to it.

Midrange has a lush, neutral timbre and the right note weight! It is warm and clear with a smooth tone that is neither aggressive nor offensive, yet not overly-sterile. Fun, realistic and engaging vocals without sounding too forward like many hybrids do.

Non-fatiguing and restrained top-end without any harshness, hiss or sibilance. Adequate, well-presented accessories with more than enough assortment of eartips to give the user a good start.

MATCHING: Getting the right synergy with Meteor is pretty simple and straightforward. Due to its slightly warm-ish and thick tonality, it is best to pair with a cool-neutral sources such as higher-tier FiiO DAPs or the newly-launched TRI TK2 DAC/Amp.

• Using third-party eartips such as Audiosense S-400, Acoustune AET08 and AZLA SednaEarfit Light give different flavors to the sound. Meteor responds well to these eartips, enhancing the overall experience.
• Use pure silver cable such as KB EAR Limpid 8-core helps tighten bass and mid-bass, improves bass control and adds the much-needed sparkle to upper-registers.

SUGGESTED PEQ SETTINGS:

• 41Hz, +4.0dB, Low-shelf
• 12,600Hz, +4.0dB, Q=1.41
• Preamp gain: -1.5dB

CONCLUSION: The TRI Meteor caught me by surprise. When I read somewhere that it has identical configurations to the ThieAudio Legacy 2, I was expecting worst or at least something similar. Well, thank God it isn’t another L2… Not at all actually.

The Meteor has an organic, cohesive and matured tonality that is suitable for a wide range of music genres. Midrange is the star of the show. It is full-bodied, smooth, intimate and musical. However, the down-sides are the sub-bass shyness and that rolled-off upper treble.

Tuning is “almost” perfect for a true technical performer. With some EQing, it can be used for critical listening or music referencing. Rated at 42 ohms (instead of the stated 12 ohms) Meteor will shine when properly driven with a clean, neutral source. At US$109, the Meteor outperforms many in-ear monitors in the same price category and even higher – for example, the US$130 TRN X7 and the US$280 SeeAudio Bravery.

Both of these I have reviewed recently and thoroughly disappointed with their performance.Well done TRI / KB EAR for giving us such a solid product at great price!

Of course, there are other solutions, such as USB galvanic isolators (either electrical or optical) and analog devices such as ADUM-chip based isolators but we are not going there… we shall focus on both iSilencer+ and JitterBug FMJ in this discussion. 

DISCLAIMER: I bought both devices AT FULL RETAIL PRICE with my own money. Thus, my verdicts are not affected or influenced by their manufacturers in any way.

Many folks approach this type of accessory with utmost skepticism. There are a few technical forums that have tested these devices with precision audio analysers proving they do nothing, thus labeling them “snake oil”… We are not going to debate that either.

To me, without actual listening, measurements, diagrams, and graphs tell us nothing about sound. Superior technical performance does not equate to musicality.

Both devices do what they advertised… That is to clean up noise and improve sound.

We shall focus mainly on their SONIC PERFORMANCE. 

Equipment used:

• AudioQuest DragonFly Cobalt
• AudioQuest DragonFly Red
• E1DA 9038S G3
• Asus Xonar Essence STU DAC
• Topping E30/L30 stack
• KBEAR BElieve
• Etymotic ER4SR
• TRN MT1 (modded)
• Lenovo ThinkPad X1 Carbon + Foobar2000
• Self-assembled Intel i7/Asus-based desktop PC + Foobar2000
• Redmi Note 9 Pro + UAPP
• Raspberry Pi 4 Model B + Volumio

Both devices are connected at the host end. As Gordon Rankin, designer of JitterBug FMJ, puts it:

“I put the JitterBug at the host side because I want all that EMI/RFI and other BS that the computer is spitting out to stay there and not get to the endpoint.” 

iFi iSilencer+

When I bought the iSilencer+, it was US$10 cheaper than JitterBug FMJ but this has changed since July 2021. Both are priced at US$59.95 now.

iSilencer+ has a plastic housing with a layer of soft rubber-coating. During installation and removal, this housing slides back and forth, which some folks may find annoying.

Compared to JitterBug FMJ, iSilencer+:

• sounds crisp with upper-midrange glare
• more open and airy
• mid-forward but rest of the frequency spectrum are thrown backward
• less bass impact, drab dynamics
• soundstage is one-dimensional
• USB noise reduction not as thorough (just a bit)

AudioQuest JitterBug FMJ

FMJ is the latest JitterBug from AudioQuest. The original had the same circuitry but no shielded enclosure. JitterBug FMJ housing is made of aluminium, feels solid and sturdy. Nothing is loose or wobbly. Size-wise, JitterBug FMJ is thicker and a slightly longer than iSilencer+.

Compared to iSilencer, JitterBug FMJ:

• overall sounds fuller and more 3D
• better dynamics and bass punch
• better depth and instrument separation
• better sense of PRAT
• cleaner, darker background

Out of curiosity and fun, I piggybacked both devices to create the “ultimate USB decrapifier”…

Host > (iSilencer+ / JitterBug FMJ) > Endpoint

Guess what happened? It actually made the sound worse. Everything sounded constricted and bone dry. I also detected slightly lowered volume gain.

So which one do I choose? Well, it depends. Ultimately, it all boils down to synergy. If your equipment is bright and cool-neutral, I suggest you go for JitterBug FMJ. If you own iFi gears, iSilencer+ does improve clarity and make the “iFi sound” less warm (or wooly).

JitterBug FMJ sounds more 3D in comparison, thus instruments and vocals are more distinctive and bodied. iSliencer+ sounds flatter in comparison. Ironically, AudioQuest DragonFly Cobalt matches the iSilencer+ better to me. Both devices filter USB VBUS/GND noise. JitterBug FMJ does it more thoroughly than iSilencer+.

Verdict

Since both devices are priced the same, it depends on availability. To many of us living in Southeast Asia, iFi products are more common and widely available. Those living in North America may find AudioQuest products easier to access.

If I have to rate both devices, I will give iFi iSilencer+ a 7 out of 10 and JitterBug FMJ an 8 out of 10. I prefer the synergy JitterBug FMJ gives to my audio gears.

USB filters are nothing new. Both iFi and AudioQuest have been making them for years. Some may find this kind of accessory unnecessary… To me, these are good to have… They DO affect sound and enhance music enjoyment to some extent. Whether or not you believe in their effects, I will leave it up to you to decide.

The post iSilencer+ And JitterBug FMJ Review/Comparison – Silence Of The Jitterbug appeared first on Music For The Masses.

Overall tonality of the Heart-Mirror is neutral-cool… Nothing offensive or harsh on the top-end. If you enjoy a clean and clear presentation, you are in for a treat.

Soundstage is average. Just slightly narrower than BLON BL-03. Imaging and instrument separation are distinct with good amounts of space around and in-between. Vocal is upfront but “not in-your-face”.

Bass is not the fastest I have heard in a dynamic earphone but it isn’t the slowest either (KBEAR Diamond is faster). I did notice bass tightens and speeds up a bit when amp’ed. However, amping doesn’t help with the sub-bass, and I feel it is lacking some low-end rumble.

A LOT OF FOLKS want to know if they really need an amp with Heart-Mirror… My answer is “YES!”… If you want the best sound from this earphone. Is it hard to drive? No! It sounds pretty decent with Apple dongle BUT the overall sound is even leaner than playing with an amp. ONE THING FOR SURE… You HAVE TO match it with a warm source (a tube amp or tube buffer for example) to sound really soothing to the ears. If not, certain tracks with saxophone or trumpet can sound quite uncomfortable.

After spending close to 10 hours with the HZSound Heart-Mirror, I could, more or less, nail down its sound characteristics. If you already own the BLON BL-05s, Heart-Mirror isn’t an upgrade (but an upgrade in fit and accessories). It is definitely an upgrade in tonality and technicality over the BLON BL-03. HOWEVER, you lose the musicality, listenability and fun-factor that the BL-03 is known for. To me, HZSound Heart-Mirror lacks richness, note weight and dynamics. These are the elements that I consider essential for an enjoyable listening.

If you already own the HZSound Heart-Mirror and would like to add some mass to its bulimic sound, here are some “weight gaining” diet you could try:

– Replace stock silver-plated cable to OFC pure copper
– Replace stock eartips to Acoustune AET08 or Final Audio Type E (black)
– Use a tube amp or add a tube buffer
– Use a warm sound source

I find myself enjoying HZSound Heart-Mirror when matched with iFi Audio Hip-Dac (XBass enabled).

Fellow Singaporean, colleague and co-blogger, Baskingshark wrote a very thorough review on the HZSound Heart-Mirror. He compared it against the Moondrop SSR, Tin Hifi T2 Plus, BLON BL-05 and BL-05s. Those who are interested in the Heart-Mirror may want to checkout his full evaluation:

Equipment used:

• Topping E30 + L30 stack
• Redmi Note 9 Pro + Apple USB Type-C dongle

The post HZSound Heart-Mirror Review (2) – Reflection Of My Heartfelt Truth appeared first on Music For The Masses.

TRI is the premium brand of KBEAR. The KBEAR TRI Starsea is a 2BA + 1DD set that comes with tuning switches for different sound signatures. Thorough review to follow.

Let me be very clear, my initial impressions of the KBEAR TRI Starsea weren’t positive… Hereby, my sincere apology to KBEAR in advance.

The TRI Starsea comes with two tiny DIP switches in four selectable tuning modes. They are – Balanced, Bass, Pure tones and Vocal. My unit came default with Pure tone mode pre-selected at the factory. The moment I insert them into my ears and press play… Holy crap! I remove them immediately… What’s wrong? Everything! The upper-mids were shouty and the notes were thin… It sounded annoying to my ears!

I couldn’t believe the TRI Starsea to be this bad, so I removed it from my ears. Using a plastic toothpick, I switched to Balanced mode. This time I lowered the volume by at least 3dB… Okay, better but the notes were still thin, with occasional shrill on louder tracks.

These tiny DIP switches are a pain to use. Unless you have slender and very pointed fingernails, it is impossible to move them. TRI did include a metal SIM card slot picker in a chic nylon case but I much rather use a toothpick to prevent scratching the beautiful imported German resin shells.

Okay, back to the sound… After trying Balanced mode, I thought Bass mode may add some note weight… True enough, TRI Starsea sounded more balanced with an ever so slightly boosted bass. From the graph, we can see what TRI actually did was to apply a wide -1.5dB inverted bell filter between 200Hz and 1Khz and +3dB low shelf rise to simulate a V-shaped tonality. Bass mode is my favorite tuning but wait! We still have Vocal mode don’t we?

Again, using my trustworthy pry tool – a toothpick, I toggled to Vocal mode…. Yikes! The shrill and thin notes came back! But it wasn’t as bad as Pure tone mode. As the name implies, Vocal mode boosts the midrange but suppresses bass frequencies, which brought back some of that glare.

So, what are my impressions of the KBEAR TRI Starsea so far? Not great… The bass lacks dynamism and energy. Music notes are anemic. Mids appear shouty and brittle when pushed. Treble is intrusive. Timbre is metallic and artificial. Tonality is cold and bland. All-in-all, TRI Starsea isn’t the most musical-sounding hybrid earphone in my collection. I remember being more impressed by the musicality of TRI I3 than this.

HOWEVER, this isn’t the end of the road. TRI Starsea, despite all these flaws, is a TECHNICALLY-CAPABLE set. Stereo imaging is exceptional. Instrument placement and separation are clear and distinct. Soundstage is tall and wide. Bass is relatively fast and tight. Overall sound signature is neutral, clean and resolving.

So, I make the TRI Starsea sounds more pleasing. For me, I prefer “more meat on the stick”, therefore the Bass mode is a good start. Next I replace the stock silver-plated copper cable with a pure oxygen-free copper cable. For eartips, I find both Acoustune AET07/AET07a and Final Audio Type E (black) add body and tames that harshness.  For equipment matching, Starsea goes well with a warm source and tube amp. Although Starsea is rated at 106dB/mW sensitivity, I find using an amp sounds much fuller than using a phone. I also discovered using an amp with low output impedance helps iron out harshness and gives Starsea an effortless and more refined sound. 

Final verdict… For US$129 (some paid US$98 during promotion), TRI Starsea will appeal to folks who focus on good stereo imaging and resolution. Some may even consider it to be “monitoring-standard”. However to those who enjoy colourful music expression and pleasant tonality, Starsea can sound lackluster and sterile.

Addendum: I managed to loan a set of Thieaudio Legacy 3 (US$119.00) from a friend to compare with TRI Starsea. Two words… Fun and musical. That’s how I describe Legacy 3. In comparison, Starsea is equivalent to the nerd in class who excels in every subject but has a boring, austere personality… I think you get what I mean.

TRN V-series has always been very close to my heart. After all, I tuned almost all of their earlier models starting from the TRN V20 till last year’s TRN V90. I have to confess, TRN V90 wasn’t my intended tuning, the upper-midrange still sounded too lean, too trebly. Of course, it still sounded way better than the eardrums stabbing “icepick” V80 from 2018.

HERE OUR FULL REVIEW OF THE TRN V90s:

I am happy to proclaim TRN V90s, the successor to TRN V90, is the sound I have always wanted the V90 to be. So, is TRN V90s a worthy successor to the popular V90? My answer is a definite “YES”!

The latest TRN V90s manages to avoid all the harshness and shrillness that plagued most of earlier versions of TRN, as well as the recent BA8. The new tuning sounds a lot smoother and fuller than its predecessors. TRN finally took my advice seriously. I didn’t tune the TRN V90s, by the way.

Soundstage is taller, wider, and deeper. Imaging is more distinct. The entire presentation is more laid-back. Overall, a soothing and relaxing musical experience compared to its predecessor, which I find can be quite forward-sounding if fed with heavily-compressed music.

Comfort-wise, however, I find the original TRN V90 fits my ears better. Of course, fit is a very subjective matter. Everybody’s ear anatomy is different. For my ears, the housings of the original TRN V90 are slightly more contoured, thus they sit inside my ears more securely. With suitable eartips both TRN V90 and TRN V90s isolate noise equally well. 

If I were to nitpick a flaw, it would be that the upper-midrange can be a tad bit recessed, BUT doing so the TRN V90s managed to avoid sounding edgy and piercing at higher SPL caused by loudness changes at different frequencies based on Fletcher Munson curves. Meaning, you can enjoy the TRN V90s at higher volume without puncturing your eardrums.

To bring out the recessed upper mids, I find the original Azla SednaEarFit eartips work beautifully. Due to its longer than normal nozzle stem, SednaEarFits solve my fitting problem at the same time.

Experimenting with various cables has led me to conclude that silver-plated copper (SPC) sounds best with the V90s. Pure copper thickens the upper-bass, low-mids which slow down the pacing too much for my liking. For my listening enjoyment, a fast and definite bass punch with a good amount of heft is a must.

As we speak, I wish to remind everyone that hybrid earphones can never be compared to dynamic-driver earphones in terms of timbre quality. Earphones with balanced armature drivers will forever register that bright metallic, artificial sheen in the upper-midrange and treble region. Both V90s and V90 inherit this steely timbre.

I had a chat with the tuner. He is none other than Ming – TRN’s number 2. Ming told me he just adopted my final tuning of the V90 submitted to him back in July 2019 (yes, the one got rejected by their number 1). In other words, just like BLON BL-05s is supposed to be BLON BL-05… What a déjà vu! 

Besides the V90s, TRN also sent me their current flagship, the BA8 for my honest opinion. And honest I will be. Because of its higher price tag and lackluster performance, I am reluctant to recommend it to anyone except TRN fanboys. Whereas, TRN V90s offers much better value and sound performance overall… Even non-fanboys will agree. 

TRN V90s, with its wallet-friendly price, engaging yet gentle tones help soothes our hearts and soul, bringing peace and harmony that attain musical nirvana.

The post TRN V90s First Impressions And Measurements – Bringing Peace To My Heart And Soul appeared first on Music For The Masses.

The story behind BLON BL-05s is quite an interesting one but earphone development is an extremely boring subject thus I don’t want to bore you with too much detail. Let’s keep it short and sweet. All-in-all, its development stretched a total period of about 10 months.

Life of the BLON BL-05s did not begin after BL-05, rather it started after BLON BL-03. The idea was conceived when BLON wanted Jurgen’s and mine input on how to improve the BL-03. Both Crinacle and Hawaii Bad Boy contributed their valuable opinions as well. The intention of this tuning was meant to be an upgrade from BLON BL-03.

So how did the original BLON BL-05 come into the picture? During the fourth quarter of 2019, BLON was experimenting with the idea of piezoelectric drivers and they included it into their BL-05 earliest prototype… Which we know turned out to be a total flop thanks to a well-known friend’s over-enthusiastic YouTube review. The idea of a piezoelectric-equipped BLON BL-05 thus disappeared into thin air.

To cash-in on a higher-priced earphone, BLON banked on the success of BLON BL-03, dropped the piezoelectric driver and sold BLON BL-05 for almost 2x the price. Yes, the BLON BL-05 had cleaner bass and midbass compared to BLON BL-03 but was cursed by the “see-saw effect”. That is whenever bass is lowered, treble MUST be reduced if not the tuning will sound bright and harsh – similar to levelling a balancing scale beam. Eventually, the BL-05 was mercilessly bashed by both Crinacle and HBB… Of course BLON wasn’t pleased at all.

Aggrieved by the outcome, BLON decided to engage help from a close friend. This close friend contacted both Jurgen and myself (also our close friend) to re-tune the BL-05. After experimenting with their 3rd generation CNT driver (which has a thicker CCAW voice coil compared to 2nd generation), BLON sent us the “BL-05 MK2”, which sounded quite good… Almost Hana-like… Both Jürgen and I liked it… BUT… A slip of my tongue triggered BLON to scrap the tuning, and that is “Hana-like”. As we know Tanchjim is a business client of BLON’s, so it is definitely a no-go.

After a few WeChat correspondence with our common friend, BLON finally decided to base the final tuning of the BL-05s on my BL-03 improvement proposal “blueprint”. Hence, BLON BL-05s can be considered a BLON BL-03 “Mark 2”. 

If you wonder what the future of BLON BL-03 lies… Will there be a “real” BL-03 Mark 2 or BL-03s (whichever name it shall be called)… Well, I can’t foresee the future but there is a plan for a BL-03 successor. Meanwhile, enjoy your BLONBL-05s… It is worth waiting 10 months!

A note on Beryllium drivers in earphones.

The upcoming US Presidential Election, the ongoing COVID-19 pandemic and the frequent AliExpress packages delay aside, 2020 is a great year for the audiophile community. The technology of beryllium diaphragm is currently in its matured state. Several headphone manufacturers have re-ignited the interest in the material by bringing more affordable beryllium driver-based products to the masses. Beryllium is renowned for its low density, high tensile strength and high flexural rigidity – an ideal material for transducers. This article will explore beryllium as a high performance material in audio applications.

Beryllium is a material with the symbol Be and its atomic number is 4 on the Periodic Table of the Elements, atomic weight 9.012182, is the lightest alkaline earth metal. As a free element, it is a steel-grey, strong, lightweight metal; lighter than commonly used aluminum and titanium, and its strength is 4 times that of steel. An indispensable and precious material with applications ranging from x-ray tubes to scientific instruments and precision components. It is also widely-used extensively in aerospace, telecommunications and metallurgical industries.

Beryllium has a reputation for being brittle. At room temperature, beryllium is inherently a “hard” metal with closely-packed hexagonal crystal structure. However, the level of brittleness is process related. There are two processes that are currently used to manufacture beryllium transducers – Physical Vapor Deposition (PVD) and Powder Metallurgy (Powdered Metal).

Beryllium has exceptional stiffness of a Young’s modulus 287 GPA. The modulus of elasticity of beryllium is approximately 50% greater than that of steel. The combination of its stiffness and a relatively low density results in an unusually fast sound conduction speed in beryllium at about 12.6km/s under ambient conditions.

The advantages  of beryllium as a diaphragm material have long been acknowledged. Its exceptionally high stiffness-to-mass ratio is far beyond that of polymer or carbon-based materials, allowing beryllium to deliver even tighter, faster and cleaner bass response. A midrange that is natural-sounding, fuller with exceptional details and texture. With the rigidity and elasticity of beryllium, the treble can be extend even further without harshness or grain, resulting in a transparent, crisp sound that is comfortable for long listening sessions.

A diaphragm, for example, should move in a perfect pistonic motion (like a piston), with all points moving in uniform and only in the desired direction. Breakup occurs when the forces acting upon the diaphragm overpower its structural integrity and different points on the surface begin moving in different times relative to one another. Because beryllium is extremely light and stiff, it does a better job of maintaining its structural integrity under load, avoiding breakups when compared to conventional diaphragm materials. Beryllium stays pistonic throughout the same frequency range which tracks signal more accurately when an equalisation is applied. Thus making it more responsive to tone adjustments.

Even more critical, however, is the efficiency at which sound travels through beryllium. This is important because the frequency at which the first breakup occurs in any metal, is analogous to the speed of sound through that metal. The speed of sound through beryllium is nearly 2.5 times faster than that of aluminum or titanium. This means the first breakup will occur at a much higher frequency – well outside the audible range in most cases. What is more, when breakup does occur, beryllium’s greater stiffness ultimately reduces the amplitude of those breakups, resulting in very low harmonic distortion.

High frequency breakups cause rough and “peaky” frequency response that typically resulting in a long decay in the time domain (also referred to as ringing). This effect is particularly evident in the top octave response and decay differences between the smooth, fast-decaying beryllium driver and the peaky, long-ringing ribbed titanium driver.

Over the years, companies such as Focal, Periodic Audio, Dunu, Campfire Audio, Final Audio and Master & Dynamic, etc, have offered beryllium-based headphones. Despite its many benefits, beryllium has never been adopted as widely as polymer or carbon-based drivers, and has mostly been relegated to esoteric head-fi components. This is due largely to expense and complexity, since beryllium is rarer and traditionally more difficult to isolate and refine. But modern day refining and manufacturing techniques are reducing the cost of beryllium, while at the same time further enhancing its performance and reliability.

With recent launches such as Dunu Luna and Final Audio A8000, as well as the-soon-to-release KBEAR BElieve, audiophiles will have more choices for affordable beryllium-based earphones. Indeed, 2020 is a year to rejoice!

KBEAR TRI I3 has been around since the 3rd quarter of 2019. It was launched at the same time together with KBEAR Diamond, which received all the attention while the elder sibling was largely neglected. TRI I3 rose to fame slowly but gradually. It gained recognition in Japan after very successful sales. Ever since, the I3 has always been on backorder because the Japanese are buying them faster than TRI can churn them out.

In the West, similarly TRI I3 gained fame and recognition slowly among the head-phile community, especially the tri-brid earphone enthusiasts. A few of them even prefer it over the very popular BQEYZ Spring (first version). A quick search on Google reveals not many reviews of TRI I3 on English websites, at least not as common as on either Japanese or Korean websites. 

In May 2020, KBEAR sent me a TRI I3 in exchange for my honest review. Personally, I am not a fan of doing reviews however I could sense the potential in this earphone. After receiving the I3, I took a quick listen. It has a luscious and fluid sound that many Chi-Fi earphones lack. At that time I was also testing the KBEAR KS2, so having the TRI I3 around is like taking a short break from work. The I3 was an instant relief from the aggressive tonality of KS2. 

Subsequently, my colleague Baskingshark wrote a definitive review on Audioreviews, titled “TRI I3 Review – Smooth Operator”. From his review we know the TRI I3 has a balanced and coherent sound. It excels in staging and is good for non-fatigue listening. Also, it needs a headphone amp to shine.

My listening impressions largely coincides with Baskingshark’s. In addition, I would like to add that TRI I3 has a “grand” presentation. Everything sounds bigger, taller, bolder… As if your set lunch has been “super-sized”. My only nitpick is its mid-bass is a bit too much (slight bloat). It gives warmth but it also adds a layer of haze. Upper-mids and treble are fine except it is a tad less detailed than what many people would consider good resolution, and it does lack some top-end extension and air.

My apology to KBEAR… I don’t want to do a review. Instead I will do a tweaking blog, just like the one I did for KBEAR TRI I4. It will be a very simple tweak. Nothing fancy… No 3M Micropore tape mod… No poking holes on filters, and definitely no dismantling.

Let’s look at the two basic components that affect sound in an IEM – mainly the cable and eartips. I am sure some of you will start crying “snake oil” when I mention the word “cable”, but like it or not, cables do affect tonality to a certain extent. The logic behind may not be scientifically-proven but the effects are obvious enough to be heard.

– Let’s look at the first component: cable.

The stock cable that comes with TRI I3 is a 4-core 4N OCC copper cable. OCC copper has a tendency to elevate bass and midrange, so this copper material isn’t ideal for the I3.
To establish a baseline, I hooked up my trusty Yinyoo 8-core tin-plated copper cable to the I3. With this cable, bass tightened slightly (but not reduced) and midrange clarity improved. Still not the results I wanted.

My past experience with stereo hifi systems tells me that pure silver cable helps suppress, tighten bass and lower-midrange. At the same time adds sparkle and clarity to treble and open up treble regions. Immediately, I contacted Yinyoo if they have a high-purity silver cable which they can suggest to me. They recommended the 4-core 7N pure silver cable at $62. Well, it is a small price to pay for big improvement.

– The second component to consider are eartips. The stock eartips that come with I3 are “loudness” eartips. How so? Similar to the loudness switch on many vintage amplifiers, this eartip lifts both bass and treble (yes, a V-shaped boost)… Which again, isn’t a good choice for I3.

I am looking for eartips that will reduce bass and midbass yet leaving upper-midrange and treble mostly untouched. For this task, I have Ortofon silicone eartips (€11 for 3 pairs) in mind. I had these eartips with me for a while but I hardly use them because they thin out low frequencies, sometimes a bit too much. It looks like I can make good use of them in this project. Alternatively, Tennmak Whirlwind has similar effect but tonality and comfort-wise, I still prefer Ortofon.

With both components in place, here is how the synergy goes… 
Overall tonality is so much more coherent with upper-midrange and treble “open-up”. Yinyoo 7N pure silver cable helps clean up treble, tighten bass and mid-bass, improves overall clarity, as well as solidify stereo imaging and instrument placement. Ortofon silicone eartips help suppress mid-bass, reducing a bit of that woolly-warmth that plagues the stock I3.

Further adjustment of 5 to 6 dB gain at 5KHz at a Q-factor of between 1.5 to 2 on parametric equaliser (PEQ) helps improve resolution and adds sparkle. Resulted in a sound that is both buttery-smooth and crystal-clear at the same time.

These executions are straightforward, simple and can be performed in a few minutes. Of course, you will still have to fork out your hard-earned money for the silver cable and eartips before you can experience any improvement.

The basic sound characteristics of TRI I3 that everybody loves and enjoy largely remain with this tweak. What you gain is clarity, a balanced tonality and richer music texture. You do get a slight increase in resolution but don’t expect to hear more micro-details than it has, unless you are prepared to remove the filter behind the nozzle screen. Then again, tri-brid earphones are tricky to tune. Even I have trouble making them sound right. Therefore, I prefer to keep the innards of the I3 intact to retain its silky-smooth signature.

TRI I3 proves that a tri-brid earphone, when done right, can sound magnificent. Once tweaked, I3 owners will be able to ascent their beloved earphone to the next level. A grandiose makeover for this Grandioso is definitely worth a try!

When I first received the news that KBEAR was planning to launch another budget IEM, I was wondering why another one, since they already have KB04, KB06 and KB10 to cover the base of their budget segment. KBEAR was all excited over this new earphone, claiming it was tuned by the same person from one of the most popular Chi-Fi brands, which I shall not name due to an agreement between myself and the manufacturer. I was actually looking forward to it because of this bold claim. 

Due to resurgence of COVID-19 cases in Mainland China, AliExpress shipment was delayed. My unit arrived late. Jürgen’s set arrived few days earlier than mine. He was impressed by its soundstage. Eventually when I did receive the KBEAR KS2, I wasn’t entirely awe and here is why:

– Bass was a tad too much for my taste. I like bass don’t get me wrong but this bass to giving me listening fatigue. 

– Upper-midrange sounded etched. I don’t mean harsh or edgy. It sounded as if somebody had over-sharpened an image in Photoshop. That’s my best description.

– Timbre sounded unnatural and dull.

I contacted KBEAR via WeChat and was immediately hit by their futile rebuttal – Jürgen likes it, why don’t you? … You are nitpicking on something that cost so little. You know we use better drivers than XX brand, thus more expensive to produce… It is selling like hotcakes in Mainland China and Japan, etc, etc… Yada, yada… Okay fine! Let’s wait a few weeks more to see how many positive reviews the KS2 can garner. It is pointless debating over this right now.

KBEAR came out a bizarre proposal. They want me to compare KS2 against the Sony IER-Z1R. Some audiophiles in Mainland China did a comparison with the Sony flagship and were praising how good it was. Okay, fine. Let me arrange with my buddy at Sony Singapore. I will do the comparison (check our Facebook discussion page for the comparison). 

True enough, one of the few negative reviews that came in was from fellow Audioreviews.org Facebook group member Jason Lucas. He did a YouTube video stating he didn’t like the KS2 as much as KB04. Subsequently more reviews were posted and KBEAR went completely silent.

So, this review is for the company KBEAR, not for KS2. 

KBEAR/TRI is a young Chi-Fi company. They didn’t have much success in their early attempts such as the F1, Opal, Hi7, KB06, KB10, etc. Last year, they contacted Jürgen and me to tune the Diamond and KB04, which eventually lead to some hype. However due to their past failures, many audiophiles are reluctant to buy their earphones. The Diamond and KB04 did not gain sales. Partially also due to the Diamond’s strong bass and recessed midrange.

Like most Chi-Fi companies, KBEAR wants a piece of the pie, too. They engaged several reviewers, Jürgen and myself included, hoping to hype their products. Unfortunately, to the western ears, these products are tuned either too harsh or too bass heavy. It is difficult for reviewers to recommend their products with a clear conscience.

I want KBEAR to become successful but first they must learn to listen to their customers and take the suggestions and opinions from their overseas “guest tuners” more seriously. Read and understand what audiophiles prefer and enjoy. Don’t rely on Chinese, Japanese, or Korean sales. These markets do not represent the majority. No doubt, both China and Japan generate the most sales, however KBEAR must realise the fact that when the western worlds give recognition to a product, it will influence the consumers in both China and Japan eventually. Give the audiophiles what they want instead of expect what they want.

KBEAR KS2 can become successful if they want to. Just decrease the bass and smoothen the treble. It is already a winner in having one of the widest soundstage and fast clean bass in the current Chi-Fi budget earphones lineup. Why stop here?

Real KBEAR KS2 Reviews

This is a follow-up to my colleague Baskingshark’s review titled “Audiosense DT200 Review – A Warm Embrace”. By now, most people know I dislike writing reviews, as such I won’t emphasize on the same remarks Baskingshark had made. Since the DT200 is supposed to target that Asian markets, mainly Mainland China, Hong Kong, Taiwan, South Korea and Japan, I will be giving my opinion solely from an Asian perspective.

As always, I would like to thank Nappoler Hu of HiFiGo for providing the review sample.

If I have to summarise the sound of DT200 in one word, it will be “lackluster”. Bear in mind I am evaluating this earphone based on my understanding of Asian-oriented tuning. If you are living in the west or you have western taste, you may find the tuning of DT200 acceptable and suits your taste.

To put my points into perspectives, the first song I fired up was Singaporean Vanessa Fernandaz’s I Want You [track 2, Groove Note Records, GRV1200]. This soulful interpretation of Marvin Gaye’s 1976 hit song is a rather interesting one with Vanessa’s thick but broad vocal range and Alex Al’s big fat bass. Here comes the first challenge for the DT200. To separate breathy vocal and big fat bass requires good definition and correlations of both drivers. Unfortunately, DT200 didn’t do too well in this aspect. The entire song sounded wooly and coagulated. And because the soundstage is tilted backwards and narrow, Vanessa sounded as if she was muttering, with Alex Al’s dominant bass overwhelming her.

The second song was a very popular Chinese song from King of Asian Pop Jay Chou ( 周杰倫 ) and Fei Yu-ching ( 費玉清 ) in a duet 千里之外 or Faraway [track 3, Sony Music, UPC 0886970030229]. This is a slow song with Jay Chou leading the vocal section, with Fei Yu-Ching coming in the second quarter of the song. At this point the bass beats become more prominent. This is where the DT200 flounders. Both singers’ voices become virtually indistinguishable. The only tell-tale sign is Fei Yu-ching has the tendency to drag his vocal chord longer than Jay’s. If DT200 is to target the Chinese-speaking markets, it has to do better than this.

The third song I tested was from the frontman of Japanese rock band Anzen Chitai (安全地带), Koji Tamaki’s (玉置浩二) trademark ballad ワインレッドの心 or Wainreddo no Kokoro / Wine Red No Kokoro [track 2, BMG Fun House, FHCF-2447]. This song is the ultimate “acid test” for male vocal articulation. Koji Tamaki’s voice is deep, throaty and dry. The instruments section almost overpowers his voice but through a good pair of headphones, one has no problem hearing him clearly. Again, the DT200 didn’t do too well picking up his thick husky voice. The instruments completely drowned Tamaki’s masculine voice, robbing the life out of the entire song.

Okay…. Maybe I am too critical of the DT200. I should give it a chance to shine. Well, I have to say it did shine… after tip-rolling. Initially I was using stock tips. Not good! So I swapped to SpinFit CP-145. Better, but the midrange sounded scooped. Several eartips later, I finally settled on Acoustune AET07. These eartips brought out the midrange nicely without thickening the mid-bass, which gave better definition to the low-mids. And since this is a review set, I wouldn’t want to mess with the cable. To be honest, the stock cable looks very good and it closely resembles Lyre Acoustics Litz cable.

Do I recommend the Audiosense DT200? Frankly, I am not a fan of the tuning. The supposingly Asian-tuning is misleading. As an Asian myself, I don’t think it will appeal to many. Asians normally prefer more bite and edge in their music, and the DT200 barely gives a soft chomp. However, DT200 seems to have gained some recognition and garnered positive reviews from its western audiences. An earphone tuned for the east but somehow got accustomed to the western ears… Lost in translation maybe?

I have mentioned on Audioreviews.org Facebook group that I do not wish to do a full review on the TRN-VX. Instead, I will let my sharp-eared colleagues do the honours. The reasons are… First, being one of the tuner of this 7-driver hybrid earphone, I don’t want to contradict myself in any way possible. Secondly, it isn’t to anybody’s interest if I proclaimed it to be the next best thing since sliced bread. And finally, if I do pass any negative remarks, it makes me look like I am trying to bail myself out with lame excuses. Therefore, I will just highlight some of its deficiencies and how they can be overcome and improved without complicated modifications.

The idea of taming upper midrange/treble peaks with 3M micropore tape goes back to super best audio friend/head-fier james444. We have covered it in detail in our modding 101 section.

1. Harsh treble

This characteristic is nothing new to many TRN aficionados. Almost every V-series flagship earphone since V80 has inherited this 8KHz peak! This peak can be lowered using parametric equaliser or PEQ app at 8Khz with a Q-factor of between 2.5-3.0. I use Toneboosters EQ (an auxiliary add-on for USB Audio Player Pro app) on Android and Peace EQ on Windows.

2. Brittle or ‘glassy” upper-midrange

I have introduced the 3M Micropore tape mod to our Facebook group, and I will reiterate it again. The logic behind this is simple. Out of the VX’s 7 BAs, 2 of them are located inside the nozzle. These two BAs are aiming directly into your eardrums. 3M Micropore tape acts like a filter and damping material that reduces sound energy to your ears by couple of decibels.

3. Tip tips

Most IEM benefits from rolling eartips, VX is no exception. I was experimenting with various silicone eartips and I have good success with Final Audio Type E, JVC Spiral Dot, Azla Sedna EarFits Light, Canal Works CW dual nozzle and SpinFit CP-145. Reversed KZ Starlight eartips thin midrange further so I don’t recommend using it.

4. Traditional snake oil remedy – cable

TRN-VX seems to be more cable sensitive than its predecessors, thus I have added this section to make all the cable skeptics scream in protest. When TRN sent out their samples, they have included their latest T4 OCC copper cable in the bundle. Frankly, this cable brings out the worst of the VX. It is both lean and harsh. Jurgen and I have good success with the $8 Yinyoo 8-core OFC copper cable. Just avoid any cable made of OCC, silver-plated or pure silver that tends to add glare to the already-bright earphone.

De-toxification?
The tuning of TRN-VX isn’t completely toxic. If you could overlook the harsh and willing to do a bit of DIY mods, experiment with eartips and cables, it is actually quite a good IEM for US$70. Bass is responsive, textured and clean. Resolution is exceptional at this price point. Spatial perception is open, airy with good extension. Its timbre is probably the best of all the TRN models, thanks to the new 10mm dynamic drivers.

Thus, when Vannak Pech claimed that “TRN- VX can spoil your hearing”… Inside my little mind, I told myself “Yeah… Literally!”

Enjoy the music!

When KBEAR sent Jürgen and me the KB04 beta for tuning, we were still halfway through fiddling with the KBEAR Diamond. The former, being a less important “candidate”, was put aside until a much later date. We gave Diamond our 200% attention. KBEAR did mention to me (not Jürgen) briefly the KB04 was going to be their new budget model. 

When we did eventually get to the KBEAR KB04, we were exhausted by the excitement over Diamond. I have to admit that I didn’t bother to give it a good listening. My initial impression of the KBEAR KB04 beta was good. Nothing offensive that needed my immediate attention, so I didn’t get back to KBEAR promptly as I normally would. However, Jürgen did highlight the mids being a tad shouty.

I did some minor adjustments on the tuning console. Somehow, reducing midrange “shoutiness” dulls the overall sound and rendered it lifeless. I told Jürgen about it. From our experience with the Diamond, we know cable and eartips can make or break the sound of an IEM, and so Jürgen suggested maybe KBEAR could match the earphone with right “accessories” to tame the midrange a bit. 

Another few weeks had passed, and KBEAR was busy promoting Diamond. They didn’t contact me again until one fine day, I received a WeChat message asking how Jürgen and I feel about KBEAR KB04. I told them it needs a good cable and eartips. I was immediately hit back in protest – “blah, blah, blah… this is a budget set, if we include fancy cable, it is going to increase the cost… ” Okay, okay… Cool down. I didn’t want to agitate her further, so I told KBEAR to go ahead with the final tuning. The earphone sounded fine to us.

Subsequently came Chinese New Year, then the COVID-19 pandemic and the Great China Lockdown. At the same time I was busy with other projects. The presence of KBEAR KB04 left my memory completely. Then in March, out of the blue I received a WeChat message from KBEAR. This time informing me KB04 will be launched by month’s end. I tried to recall which earphone KB04 was… I dug up the frequency response graph… Oh, that one! And so, I posted it on the Audioreviews Facebook page.

So, what is KBEAR KB04 and how does it sound? I believe there are many talented reviewers out there who can write and describe sound better than me (such as my colleague Loomis Johnson), so I won’t go into that. What I can share here are its shortcomings and which kind of audiophiles the KBEAR KB04 will appeal.

– First of all, do understand that the KBEAR KB04 is a budget IEM model… Meaning everything has been skimmed to most basic to save cost. 

– KB04 is tuned for beginners and amateur audiophiles in mind… In another word, it is suitable for newbies who are still discovering their sound preferences.

– Since KB04 is tuned for newbies, it has a “safe” tuning. Meaning, it will appeal to most people (both audiophiles and non-audiophiles), and is suitable for a broad range of music.

– And since this is a budget model, those advanced-amateurs or expert audiophiles can give it amiss. If you insist on buying a set, PLEASE LOWER YOUR EXPECTATIONS AND DON’T NITPICK – KB04 was tuned by amateur tuners still in diapers.

– To get the most from it, you will have to spend more than US$30. Put aside at least $20 and invest in a good set of cable and eartips. If you already own some, do a mix and match to find the right combination.

– If the upper-mids glare bothers you, do a 3M Micropore mod on the nozzles. That will smoothen the sound a little and makes it more palatable to treble sensitive ears.

If all of the abovementioned seem reasonable and acceptable to you, order a set, enjoy it and be happy.

Every audiophile has a starting point, Jürgen and I are glad that you use KBEAR KB04 as your launch pad. Slowly but surely, you will grow in this hobby, and so is your earphone collection. By then, KB04 will be a distant memory to you as well.

Happy exploring…

Disclaimer: If you are allergic to or a skeptic of “snake oil”, please stop reading NOW!!! The following article consists of potent extracts and essences from some of the most venomous snakes on the planet, such as inland taipan, taipan, black mamba, viper, coral reef snake and king cobra, etc… Read at your own risk!

The 1BA + 1DD hybrid TRI I4 was released in August 2019. Reception then was lukewarm and less than ideal. Many reviewers didn’t find the TRI I4 exceptional. Co-blogger Loomis Johnson wrote an article on it (see: TriAudio I4 Review – The Schizophrenic Debutante) in September 2019. He wasn’t impressed with it either.

My TRI I4 was a review sample supplied by Wooeasy store. That time I remember lady boss Mrs Easy told me TRI I4 was receiving many positive feedbacks from her Japanese clients and insisted that I should give it a try. 

Well, I did try and didn’t like it… But I didn’t hate it either. I found the coherency and speed between the 10mm biocellulose dynamic driver and the Knowles balanced armature driver to be mismatched somehow. Bass decay sounded sluggish and boomy. Midrange wasn’t perfect either. It was slightly recessed and distant, resulted in male vocal sounding weak and lean. However, female vocal was near perfect, with nice air and no hint of upper mid sibilance. Treble was well extended with plenty of air and space. Highs were clean and detailed.

As I was busy with other tuning projects that time, I didn’t want to spend more time with the TRI I4. It was tossed into the drawer and left there for months until recently… Hate me for saying this, but thanks to the novel coronavirus, I was able to revisit and re-evaluate the TRI I4 once again. This time, I am pleased to proclaim it is one of the best budget earphones I tried and tested in 2019!

How so? What did you do? [“SNAKE Oil” ALERT!!!] Simple… First, I give it enough burn-in time and second, I replaced a couple of “accessories”. After Mainland China went out of action during the COVID-19 outbreak, I was deprived of new toy. Thus, I took out the I4 from the drawer to try. Recalling the rather unpleasant experience, I let it run-in for few days (roughly 50+ hours). I also found my long-lost Neotech 7N UP-OCC 8-core pure copper cable that a friend of mine DIY’ed himself and sold to me for quite a good price (I know keep saying I am cheap but I actually paid much higher price for this cable than many cables on AliExpress). I tossed out the stock cable and replaced with Neotech UP-OCC and…. Viola! I experienced both exhilaration and happiness at the same time.

Earlier I mentioned I4 suffered from slight bass bloat and slowness, well, both problems were gone after I swapped to Neotech UP-OCC cable. Voices rendered beautifully especially female vocals. The only problem left was male vocals still sounded weak and lacking. Fret not, I had a solution for that!

At the time of writing, I was also compiling a list of silicone eartips and their effects on sound. I remembered testing a set of eartip that would enhance vocals – both male and female, and that was Radius Deep Mount from Japan. True enough, vocal clarity rose by a few notches and male vocals no longer sounded anemic. The Deep Mount eartips also enhanced the overall balance of the I4 and presented a much wider, bigger soundstage and airiness.

With all these enhancements, I am pleased to reveal TRI I4 gives the much praised Tin Hifi T4 (SRP at US$109) a good run for the money. After tweaking, both Tin Hifi T4 and TRI 4I4 share many similar traits. But T4 sounded drier and a tad more indented, thus less engaging when it comes to vocal tracks. My usual test tracks from Vanessa Fernandez, Diana Krall, Harry Belafonte, Kenny Rankin and Malaysian mando-pop group 2V1G, sounded superb!

At SRP US$69 (you can get it for as low as US$50 during  AliExpress sales promotion), TRI I4 is definitely worth exploring. The I4 was last year’s model but it didn’t gain fame until recently. Even Bad Guy Good Audio Reviews Chris brought it to attention in one of his many long-winded YouTube videos. Chris and I disagree on many things but both of us agree TRI I4 is definitely an interesting one to consider if you are tired of conventional Harman Target tunings. 

Let’s take a bow… The debutante has left the house but do catch a glimpse before she is gone for good!

Thanks to Wooeasy Store for sending the first tuning beta. I received the beta two days after Crinacle and Hawaii Badboy (Chris) got theirs. Chris made a YouTube video with graphs.

Crinacle wrote a short comment on Discord. After both commented, I knew roughly what to expect from the BL-05 more or less.

However when I put them in my ears, my anticipated smile turned into a drooping frown faster than Usain Bolt could reach the finish line. The treble is way too peaky!

There are plenty of details though but in the wrong places. Vocals sounded harsh and brittle… Timbre is artificial… I can continue the long list of negatives but in short – no way is this earphone going to the stores.

This is when my job as a tuner comes in. I posted my listening impressions on Audioreviews.org Facebook page. Then I posted comments on both Audioreview and NBBA (No BS Budget Audio) Facebook page seeking suggestions on what audiophiles want from the new tuning.

Next I posted a several graphs on Audioreviews.org to collect opinions and suggestions. It is a TEAMWORK!!! Crinacle shared his concerns. Many have posted their opinions too.

Special thanks to Erlk Ikomori, Yannick Khong, Andrew Grimshaw, Sandeep Shetty, Brian Wheatley, Matt Batista, Rodrigo Rodrigues and many friends of Audioreviews.org (apology if I missed out your name).

I have done a rough tuning and will submit the parameters to BLON after Jürgen received his BL-05. As of now, I am quite satisfied with the new tuning. Let’s keep our fingers crossed that BLON will accept and approve the “new sound”.

We shall NEVERGIVEUP!!!
