The Sennheiser IE 600 are the company’s V-shaped signature iem for the aspiring audio aficionado – and a lower-priced alternative to their IE 900 flagship with a wider appeal.

This analysis is based on >4 months of auditioning. I thank Sennheiser USA for this opportunity.

Introduction

Sennheiser headphones have been my first love in the late 1970s, when I picked up a pair of the legendary HD 414 with their shiny yellow ear pads at a flea market. Through the years, my collection grew, first by the company’s famous M-series earbuds, later by their early earphones that cropped up simultaneously to the iPhone.

While Sennheiser’s headphone have been a standard staple for a long time – their still current HD 25 go back to the late 1980s used for noise isolation on the Concorde ultrasonic airplanes) – and their HD 600 have been a favourite since 1997. The company’s first “worth writing home about” earphones may have appeared around 2015 with the “Momentum In-Ear” model, which were sonically limited by their bassy, overly V-shaped tuning.

Their 2019 Pro series [IE 40, 400, 500 ] was also rather a mixed bag in the eyes of many. Sennheiser were stubbornly holding on to the dynamic driver principle whereas the world was going “hybrid”, that is implementing a combination of several balanced armature drivers with (or without) a dynamic driver as a woofer. These hybrids may achieve a better clarity but also sound less natural and frequently incoherent, as they rely on crossovers.

Sennheiser countered their doubters with their 2021 introduced IE 600 and pricier IE 900, and even an excellent budget model in the IE 200 in 2023.

Physical Things and Usability

The Sennheiser IE 600 shares a lot of physical features with the big IE 900 brother such as shells, drivers, cable type and other accessories. The biggest difference is the shells’ material, the lack of a 2.5 mm cable, and the tuning.

In the box you find:

The precision-milled and anodized aluminium housings follow the company’s IE 900, IE 200 and (discontinued) IE 300 models, shape wise….and therefore comfort wise. Fit and comfort have highest priority for me, and the small earpieces score 10/10.

Unfortunately, all these models have the same silicone eartips which don’t fit my ears at all; I used long-stemmed Azla SednaEarFits (“toilet plungers”) instead, which also produce an excellent isolation.

Two cables are included for single-ended 3. 5mm, and balanced 4.4 mm circuits. They are pretty non-descript in their visual appeal but pragmatic. The MMCX connectors are slightly different from the standard ones, you have to be careful when fitting third-party cables.

Tonality and Technicalities

The Sennheiser IE 600 has a warm-neutral V-shaped signature charactered by a punchy, authoritative low end and an energetic midrange, tuned to please the affluent mainstream listener. You may call it “feel-good tuning”, I’d call it “more-of-the-same” well done. Since I am a big fan of the “flatter tuned” IE 900 and IE 200, I have been struggling with the IE 600 a bit…a luxury problem?

As the human ear hears the whole frequency spectrum in context, the graph deceives the low-end perception a bit: there is lots of sub-bass with superb extension, and lots of mid-bass, which, coupled with the elevated upper midrange, moves the IE 600 into classic V-shaped territory.

Low-end has lots of rumble, lots of extension, and the midbass has a small hump, which results in a bit an exaggeration (“compared to natural”). The bass could be a bit crisper, cleaner, harder, and speedier, and threfore less thick.. I’d call it “pleasing’ but also a bit “perfumed”.

With the Azla eartips in my ear canals, the mid-bass definitely smears a bit into the lower midrange and affects vocals. I occasionally find that a bit “ordinary”, though most listeners may like that. This is very high level criticism.

Nevertheless, the smear affects midrange transparency and clarity but delivers an extra serving of dynamics and pizazz without being overwhelming.

On the upside, vocals are richer in the IE 600 compared to the IE 900, reinforced by the mid-bass influence. Male and female vocals are organic, full, and a bit back, but the mid-bass rounds the corners maybe a bit much. I’d like to hear more midrange clarity and transparency. Even the treble is overshadowed by the bass rumble. Perceived treble extension and treble resolution are just average. Cymbals could be better carved out.

Treble is also a bit subdued with cymbals resolving reasonably well, but way behind the IE 900. I find them a bit tizzy.

Soundstage is average in all dimensions, Resolution is definitely behind the IE 900. Overall, the IE 600’s tonality is somewhat “common”, middle of the road at a luxury level.

Your money is again in the timbre and cohesion, as with so many Sennheiser models. The IE 600 just sound natural and out of one mould. I’d prefer them any day over similarlly priced hybrids.

In comparison, the easier-to-drive IE 900 have a tighter, less thumpy low end and a leaner midrange, which results in a better separation between the two, and also in better midrange resolution and clarity. The IE 900 also have a much superior (perceived) treble extension and resolution, and a much wider soundstage. It appears that Sennheiser have tuned the IE 600 for the mainstream popster and the IE 900 for the purist.

The Sennheiser IE 200 may be technically inferior to the IE 600, but they also have a “flatter” frequency response graph, which I prefer. The final E5000, in comparison, may be a pig to drive, but when they get enough electrical current, they offer fuller voices, more bass, but less treble than the IE 600…and a narrower stage.

To me the IE 600 have one big problem: the existence of the much more exciting IE 900. And the aficionado has the problem of the price difference between them.

Concluding Remarks

Many “influencers” assign the IE 600 Sennheiser’s flagship status [never believe an article with a headline ending on a question mark]. I completely disagree. When listening to more sophisticated music (classical, jazz), the IE 900 are far superior in the accuracy of musical reproduction imho. However, they are also far more expensive.

Hence, the IE 600 are the next best thing. My bias aside, the IE 600 are great earphones that will appeal to mainstream listeners of pop and rock owing to their punchy, V-shaped tonality. They are the logical upgrade of the IE 200, and pretty much unparalleled in their class. Although I personally much prefer the more expensive and expansive IE 900 (excuse the pun), most listeners will not agree with me. In any case was it a treat being able to audition the IE 600 and IE 900.

Until next time…keep on listening!

Introduction

I once ended up at the CES show at the Venetian in Las Vegas. This was rather coincidental, and I had been attracted more to the “adult fare” at the same hotel – also coincidentally. Having no tickets for either, I was restricted to the peripheral overflow suites. In one of them played a sophisticated stereo setup…lots of tubes and LEDs, monstrous cables and very large speakers. A huge system. The small crowd was ooh-ing and aah-ing.

Out of the speakers came…choral music by a choir. Very subtle and unspectacular. But it sounded natural and realistic. So much gear, so much investment, for so little result? I was scratching my head…and wrongly so.

What could be better than reproduction as close to the original as possible? We sit in modern concert halls listening to chamber music and symphonies, which never sounds flashier than nature allows. Isn’t that what audiophilia is all about?

I have listened to >$1000 earphones that sounded spectacular but also unrealistic: “perfumed”…and “glassy” to my ears. How good is a resolution beyond natural?

Sennheiser, a company established out of Germany’s ashes in 1945, have always stood for natural sound. My first headphones were the HD 414, today I treasure the HD 600 (introduced in 1997) and the HD 25 (introduced in 1989). Natural sound is obviously never obsolete.

In terms of in-ear monitors, Sennheiser came relatively late out of the starting blocks. They can pride themselves of inventing the earbuds (their famous M-series ), and added their first in-ear monitors parallel to the introduction of the iPhone…which had a very mushy bass.

In terms of technology, the company relies entirely on single-dynamic drivers for reasons of sonic cohesion and minimization of distortion: no BAs, no crossovers used.

Their 2015 Momentum in-ear had a decent V-shaped sound with too much bass and too little vocals for my taste. In 2019, Sennheiser introduced their pro line for musicians, which I analyzed to the hilt. In retrospect, I could only recommend the middle model Sennheiser IE 400 PRO as the best sounding of the lot.

The $350 Sennheiser IE 300, introduced in 2021, was aiming at the “consumer crowd”. At the time, Sennnheiser had experimented more with the sound chamber for improved clarity, which probably was the nucleus of their IE 600 and IE 900 developments, which reached the market in 2021. As a bonbon for the budget conscious, the 2023-introduce $150 Sennheiser IE 200 impress even the most critical listener – and they run circles about the IE 300.

Therefore, if you like the IE 900 (or IE 600) but can’t afford them, get the IE 200.

Specifications Sennheiser IE 900

Physical Things and Usability

I don’t want to be repetitive. You get information on the technical aspect in the above space, on the Sennheiser website, and right here in Alberto’s very thorough IE 900 analysis.

In the box you find:

The precision-milled and anodized aluminium housings follow the company’s IE 200 and (discontinued) IE 300 models, shape wise….and therefore comfort wise. Fit and comfort have highest priority for me, and the small earpieces score 10/10. No need for custom-made shells.

Unfortunately, all these models (and the IE 600 also) have the same silicone eartips which don’t fit my ears at all; I used long-stemmed Azla SednaEarFits (“toilet plungers”) instead, which also produce an excellent isolation. Sennheiser offers custom-made silicone eartips – but in Germany only.

Three cables are included for single-ended 3. 5mm, and balanced (2.5 mm, 4.4 mm) circuits. They are pretty non-descript in their visual appeal but pragmatic. The MMCX connectors are slightly different from the standard ones, you have to be careful when fitting third-party cables.

Tonality and Technicalities

The Sennheiser IE 900’s sonic signature can be characterized as neutral with a tinge of bright, organic, and close to the truth, with realistically rounded corners….meaning, a cello sounds like a cello and a trumpet like a trumpet: the note decay is just right. They excel with complex music (let’s say, by an orchestra) played on naturally amplified instruments (e.g. strings, wind instruments) and are truly is an iem for the purist.

What strikes me first whenever I plug the IE 900 into my ears is the fabulous treble extension and resolution, in a quality I have not experienced in an iem before. I typically don’t care much about treble, but this one is a real treat.

The low end is as it should be imho: nicely enveloping with a VERY deep extension, no mid bass hump, good composition down to the lowest frequencies. Good rumble down there, but not too thick. The bass is impactful and speedy, yet not smearing into the lower midrange. Great separation between them.

Always a good test for bass tightness is Ladi Geisler’s “Knackbass” in early 1960s Bert Kaempfert recordings (marvels of Germany sound engineering). And the IE 900s deliver it as it should be…bass guitars and drums are tight and crisp but without being overwhelming.

Voices are perceived as lean by some in the IE 900, but not to me. Male voices are certainly not fat, also not sharp, but rather realistic, well rounded, nuanced, and three-dimensionally well sculptured. The midrange also comes with great resolution, clarity, and transparency.

Female voices are full and well rounded/articular to my ears, and forward, more forward than in the HD 600 headphones. One of my standards is Stevie Nicks in “Dreams” from the Fleetwood Mac Rumours album.

Treble is one of the IE 900s outstanding features: very well resolving, very accentuated, cymbals come out better on the IE 900 as in all other earphones I have tested. They are in stark contrast to the robotic cymbals in planar-magnetic iems.

Trumpets, strings, electric guitars and pianos in the upper midrange are discreet and unobtrusive, fitting well into the mix.

Soundstage is very wide (“widescreen”) and tall, and somewhat deep, but not s as deep as, let’s say, the Dunu Zen. 3D imaging and microdynamics are excellent, you can really map the musicians on stage in 3D rather accurately.

When it comes to timbre, I cannot think of any Sennheiser headphone or earphone that hasn’t excelled in this respect. The IE 900 deliver music as close to the source as could be. Excellent clarity and transparency contribute to this without the artificial “glassiness” of most BA or hybrid earphones.

Bringing it all together, the IE 900 excel through their cohesion…the whole frequency spectrum is well balanced, nothing it overdone or neglected. Your money goes into realistic natural sonic production: music as is.

In comparison, my beloved Dunu Zen are easier to drive, bassier, therefore also narrower but deeper, stage wise, with a much spicier upper midrange. However their cymbals disappear in a hole compared to the IE 900. The final E5000 are harder to drive, warmer, have fuller male/female vocals, are bassier, but the bass is generally fuzzier (depending on source). They have a narrower stage and lack the IE 900’s treble extension.

The IE 600 are bit harder to drive than the IE 900. They are bassier, punchier, more V-shaped, and therefore more spectacular with a broader mass appeal…but they are also somewhat cruder (particularly in the treble) than the more finely woven and better imaging IE 900. The IE 600 are the exuberant teenager, and the IE 900 the more mature, laid back, older brother.

The Sennheiser IE 200 are harder to drive than the IE 900 with softer notes, a less intimate imags, and without the IE 900’s spectacular treble extension. They are nevertheless overall darn good and produce vocals very well, for example.

Concluding Remarks

The Sennheiser IE 900 are for purists, for listeners who want to enjoy music as close to the truth as possible. They don’t exaggarate and therefore don’t wow on a first listen (apart from the treble), they linger…and keep doing so. The IE 900 are clearly for the advanced listener, who dip deep into rather complex orchestral, vocal, and jazzy music.

The IE 900 may be pricey but they will hold their relevance and therefore value over the years to come. Similar to the HD 600 headphone series before, they are an investment in the future.

Until next time…keep on listening!

INTRO

Moondrop May has me looking forward to the spring given our latest arctic blast where we dipped colder than Siberia. Moondrop are notorious for challenging how much value you can get from a dynamic driver earphone. The uniqueness of the MOONDROP May is the built-in dac dongle EQ tuning feature strung unfortunately to the Android OS for now, but once adjusted can be carried across devices or applications.

Planar treble and a new Sapphire dynamic driver meld together to create something new from Moondrop Labs in the value realm with great technical abilities and optional electronic tuning in the more serious earphone price category.

DESIGN FEATURES

The Moondrop May only has a USB-C connection built into the solidly thicker than normal silver plated braided cable. Installing the tips was difficult feeling like perhaps the bore size was not matched well to the nozzle diameter, but once on they stay in place so not all a bad thing.

The unboxing experience was easier to open than past offerings and along with the mundane eartips and the detachable USB dongle cable is a premium leather zippered case that looks quite classy, but is bulky in the height dimension. It’s best in a bag or coat pocket, awkward in a pants pocket.

The Moondrop May departs from the shell shape that has been a staple through many models. I actually find the Moondrop May is less finicky for my ear shape and fits better. It is also quite isolating. Inside we have a new wideband Sapphire dynamic to handle up to 8khz where the 6mm annular planar driver takes over upper treble duty.

The USB dongle cable has minimal power drain, I measured only 0.01A or approximately 10mA of current draw. The convenient controls include coarse volume steps so a little change goes a long way, for finer control the DAP/phone may offer better control. 

Play and pause are activated with the center button. There were in some instances a faint ringing tone that lasted about 2-3 seconds could be heard when paused or even as it switched to other songs, probably has to do with the noise filtering of the DAC, the EQ (perhaps they are using convolution or minimum phase filters) or the low pass filter used to abide by Nyquist theory. I have no way to flesh that out and determine what is causing it, other than I can notice it only in the moments of silence (not during song listening).

IOS users could still use it with a camera adapter or a newer device that has USB-C over the lightning connection. Those that manage to connect will have a different experience and not be able to fully utilize the design. Moondrop Link 2.0 is required to select EQ’s being USB-C and there is no 2.0 link app for IOS. 

I am curious as to why there is no official store app. The Moondrop Link 2.0 like the original Link app is not on the Play store. You must allow 3rd party app access with the developer options. Some may view this as a security risk so use at your own peril. Users can create their own tunings and add them to the Moondrop repository by creating an account. Otherwise, you have mostly free range on the app.

It did appear buggy, sometimes my LG G8 would not recognize the device to make changes and I would have to restart the phone, but it was connected since music could be played through it. If I did not get the message to allow Moondrop to access the May, then I knew it would not be recognized. I have no way to tell if it was my phone, or the app.

SOUND

Strangely, the out of the box tuning does not match any of the downloadable target curves. I measured it first before I started playing with any of the EQ settings and was surprised to find that oversight. I am not sure if this was on purpose or accident, but either way a bit concerning.

One question I have is what is it like without DSP? Being that the cable is detachable, I connected another cable just for funsies. Graph below, surprise it matches the out of the box tuning. So to answer the question of how to get a tuning that does not exist in the presets…use a different 0.78 2 pin non-dongle cable. Given the 10dB lower treble pinna gain, this might fit better with eastern style tuning. It is too forward for my preference.

The nice thing about the presets is you can hear the change instantly without actually hitting apply to lock it in. The presets are also different than just straight EQ because it will carry across any app or device you listen to them on. Ranking the presets for my personal tastes were Standard, Basshead, Reference, Harman, No Bass. Reference and No Bass were rather close and sound a bit thin in upper bass, but heavy on upper midrange/low treble gain.

The Harman setting was thunderous and weighty feeling even more so than the Basshead tune and it adds extra treble zing. For classic rock that might be missing some midbass tone and warmth, the Basshead is the way to go, but if you want more treble essence and further thickness go for the Harman. It also increased the upper treble with cymbal shimmer.

Standard has a minor bass lift somewhere between the reference and basshead. I find the Standard and reference pretty close to balanced, but occasionally the reference could feel too thin in the mids. Bass has a tight punch and snap with either of these presets, basshead and Harman adds some slowness and can come off bloated.

Mids and treble sound realistic and never dull, however like most Moondrop products the essence of air is where they pull back the reins. To fully utilize the annular planar driver, the Harman tuning adds more air and shimmer. Overall, there could be some extra contrast but nothing that worries me. The bones or structure is in place, I think the user has to embrace the electronic tunable nature of these and unlock the full potential. Transient response is quick as expected from the planar treble, especially with the smaller driver. 

With some of the reference or no-bass presets it gets overpowering however less so than the Moondrop Starfield 2. Nothing sounds weird or off in the timbre department until you download some of the PEQ downloadable content to mimic the tunings of some of their other models.

The downloadable presets come from Moondrop, plus other users who have created accounts. I yearn for a reset button though, and also wish that by setting the presets it might carry over to the adjustable PEQ section so you could have a starting point, but add or subtract from the preset. 

Regardless of tuning, the Moondrop May never felt too crowded and provided ample instrument separation front to back and side to side. Clarity is good and what is normally found at this price range I find them near on par with the excellent Sennheiser IE200. The standard tuning is also close to what you find on the Sennheiser IE200, but there will be some differences in the midrange. Sennheiser likes to give us a more vocal enhancement that blends with the overall tuning. Jazz and classical fans would be more satisfied with the IE200.

So I mentioned the Sennheiser IE200 is a close competitor and excellent overall, it gets an overwhelming positive stamp of approval from audiophiles, the general population takes issue with the cable and fitment. The Sennheiser is a new benchmark around the $130-150 price range. The Moondrop May is half the price and one of my favorites closer in price is the Truthear Hexa. It’s not going to best the Sennheiser, but recognize it can fill the gap.

With the Hexa you get balanced bass, and equal resolution and clarity, with additional treble presence that is boosted. It sounds more V shaped with less midrange presence. The Hexa fits with modern rock and pop music, where the Moondrop May is trying to straddle the mainstream and yet still appeal to audiophiles with a more proper timbre. The Truthears Hexa also has lower sensitivity and works better with more amplification.

FINALE

Keeping in mind the Moondrop May is a $65 earphone with an attached DSP dongle it ticks off many boxes with caveats. Those being restrictions on connections and devices, app is only available on the Android platform (not even Windows or Mac OS), and has to be side loaded outside the Play store. It has technical abilities that set it apart from the ok entry level offerings, and could easily last a while without getting the itch to upgrade.

Great value too minus the bland eartips, this is a good one to have and safer to recommend over the Starfield 2. Much like the KZ VXS Pro, the built in DSP tuning is something that is carrying over from the powered professional studio monitors, and I think we will star to see more and more of this concept.

Ich danke Sennheiser USA für dieses Leihgerät, das sie mir großzügig für 4 Monate gebent haben. Ich danke Kazi für die Messungen.

Einführung

Ich bin einmal bei der CES-Show im Venetian in Las Vegas gelandet. Das war ziemlich zufällig, und ich war mehr von der “Erwachsenenkost” im selben Hotel angezogen worden – auch zufällig. Da ich auch keine Tickets hatte, war ich auf die peripheren Überlauf-Suiten beschränkt. In einem von ihnen spielte ein ausgeklügeltes Stereo-Setup… viele Röhren und LEDs, monströse Kabel und sehr große Lautsprecher. Ein riesiges System. Die kleine Menge war ooh-ing und aah-ing.

Aus den Lautsprechern kam… Chormusik von einem Chor. Sehr subtil und unspektakulär. Aber es klang natürlich und realistisch. So viel Ausrüstung, so viel Investition, für so wenig Ergebnis? Ich habe mich am Kopf gekratzt… und das zu Unrecht.

Was könnte besser sein, als die Reproduktion so nah wie möglich am Original zu sein? Wir sitzen in modernen Konzertsälen und hören Kammermusik und Symphonien, die nie auffälliger klingen, als es die Natur erlaubt. Ist es nicht das, worum es bei Audiophilie geht?

Ich habe mir >1000-Dollar-Kopfhörer angehört, die spektakulär, aber auch unrealistisch klangen: parfümiert… und “glasig” in meinen Ohren. Wie gut ist eine Auflösung jenseits der Natürlichen?

Sennheiser, ein 1945 aus der Asche Deutschlands gegründetes Unternehmen, hat sich schon immer für natürlichen Klang eingesetzt. Meine ersten Kopfhörer waren die HD 414, heute schätze ich die HD 600 (eingeführt 1997) und die HD 25 (eingeführt 1988/89?). Natürlicher Klang ist offensichtlich nie veraltet.

In Bezug auf In-Ear-Monitore kam Sennheiser relativ spät aus den Startblöcken. Sie können stolz darauf sein, die Ohrhörer (ihre berühmte M-Serie) zu erfinden, und fügten ihre ersten In-Ear-Monitore parallel zur Einführung des iPhone hinzu… das einen sehr matschigen Bass hatte.

Ihr 2015 Momentum In-Ear hatte einen anständigen V-förmigen Sound mit zu viel Bass und zu wenig Gesang für meinen Geschmack. Im Jahr 2019 stellte Sennheiser seine Pro-Linie für Musiker vor, die ich bis zum Anschlag analysiert habe. Im Nachhinein konnte ich das mittlere Modell Sennheiser IE 400 PRO nur als den besten Klang der Menge empfehlen.

Der 350-Dollar- Sennheiser IE 300, der 2021 eingeführt wurde, zielte auf die “Verbrauchermenge” ab. Zu der Zeit hatte Sennnheiser mehr mit der Schallkammer für eine verbesserte Klarheit experimentiert, die wahrscheinlich der Kern ihrer Entwicklungen IE 600 und IE 900 war, die 2021 auf den Markt kamen. 

Als Bonbon für die budgetbewusste beeindruckt der 2023 eingeführte 150 $ Sennheiser IE 200 selbst den kritischsten Zuhörer – und sie führen Kreise über den IE 300.

Wenn Sie also die IE 900 (oder IE 600) mögen, sie sich aber nicht leisten können, holen Sie sich die IE 200.

Physische Dinge und Benutzerfreundlichkeit

Ich möchte mich nicht wiederholen. Informationen zum technischen Aspekt erhalten Sie im obigen Bereich, auf der Sennheiser-Website und genau hier in Albertos sehr gründlicher IE 900-Analyse.

In der Box finden Sie:

Die präzisionsgefrästen und eloxierten Aluminiumgehäuse folgen den Modellen IE 200 und (abgesetzt) IE 300 des Unternehmens, formtechnisch … und damit komfortmäßig. Passform und Komfort haben für mich höchste Priorität, und die kleinen Ohrhörer punkten 10/10. Keine Notwendigkeit für maßgeschneiderte Muscheln.

Leider haben alle diese Modelle (und auch der IE 600) die gleichen Silikon-Ohrstöpsel, die überhaupt nicht zu meinen Ohren passen; ich habe stattdessen langgestiemte Azla SednaEarFits (“Toilettenkolben”) verwendet, die auch eine ausgezeichnete Isolierung erzeugen. Sennheiser bietet maßgeschneiderte Silikon-Ohrstöpsel an – aber nur in Deutschland.

Drei Kabel sind für einzelnde 3,5 mm und ausgeglichene (2,5 mm, 4,4 mm) Schaltkreise enthalten. Sie sind ziemlich unscheinbar in ihrer visuellen Anziehungskraft, aber pragmatisch. Die MMCX-Anschlüsse unterscheiden sich geringfügig von den Standardanschlüssen, Sie müssen beim Anbringen von Kabeln von Drittanbietern vorsichtig sein.

Tonalität und technische Details

Die Klangsignatur des Sennheiser IE 900 kann als neutral mit einem Hint von hell, organisch und nah an der Wahrheit charakterisiert werden, mit realistisch abgerundeten Ecken….das bedeutet, ein Cello klingt wie ein Cello und eine Trompete wie eine Trompete: Der Notenausklang ist genau richtig. Sie zeichnen sich durch komplexe Musik (sagen wir, von einem Orchester) aus, die auf natürlich verstärkten Instrumenten (z.B. Streicher, Blasinstrumente) gespielt wird, und sind wirklich ein Iem für die Puristen.

Was mir zuerst auffällt, wenn ich den IE 900 in meine Ohren stecke, ist die fabelhafte Hocherweiterung und Auflösung, in einer Qualität, die ich noch nie in einem Iem erlebt habe. Normalerweise kümmere ich mich nicht viel um die Dress, aber dieser ist ein echter Leckerbissen.

Das niedrige Ende ist so, wie es sein sollte: schön umhüllend mit einer SEHR tiefen Verlängerung, kein Mittelbass-Humpfel, gute Komposition bis hin zu den niedrigsten Frequenzen. Gutes Rumpeln da unten, aber nicht zu dick. Der Bass ist wirkungsvoll und schnell, schmiert sich aber nicht in die untere Mitte. Große Trennung zwischen ihnen.

Immer ein guter Test für die Bassdichtheit ist Ladi Geislers “Knackbass” in den frühen 1960er Jahren Bert Kaempfert Aufnahmen (Wunder von Deutschland Sound Engineering). Und die IE 900s liefern es so, wie es sein sollte… Bassgitarren und Schlagzeug sind eng und knackig, aber ohne überwältigend zu sein.

Stimmen werden von einigen im IE 900 als schlank wahrgenommen, aber nicht für mich. Männliche Stimmen sind sicherlich nicht fett, auch nicht scharf, sondern eher realistisch, gut abgerundet, nuanciert und dreidimensional gut skulpturiert. Der Mittelklasse kommt auch mit großer Auflösung, Klarheit und Transparenz.

Weibliche Stimmen sind voll und gut abgerundet/artikulal zu meinen Ohren und nach vorne, mehr nach vorne als in den HD 600-Kopfhörern. Einer meiner Standards ist Stevie Nicks in “Dreams” aus dem Fleetwood Mac Rumours Album.

Treble ist eine der herausragenden Funktionen der IE 900: sehr gut lösende, sehr akzentuierte Becken kommen auf dem IE 900 besser heraus wie bei allen anderen Kopfhörern, die ich getestet habe. Sie stehen in krassem Gegensatz zu den Roboterbecken in planar-magnetischen Iems.

Trompeten, Streicher, E-Gitarren und Klaviere in der oberen Mitte sind diskret und unaufdringlich und passen gut in den Mix.

Die Klangbühne ist sehr breit (“Widescreen”) und groß und etwas tief, aber nicht so tief wie, sagen wir, das Dunu Zen. 3D-Bildgebung und Mikrodynamik sind ausgezeichnet, man kann die Musiker auf der Bühne wirklich ziemlich genau in 3D abbilden.

Wenn es um das Timbre geht, kann ich mir keinen Sennheiser-Kopfhörer oder -Kopfhörer vorstellen, der sich in dieser Hinsicht nicht ausgezeichnet hat. Der IE 900 liefert Musik so nah an der Quelle, wie sie sein könnte. Ausgezeichnete Klarheit und Transparenz tragen dazu bei, ohne die künstliche “Glasigkeit” der meisten BA- oder Hybrid-Ohrhörer.

Wenn man alles zusammenbringt, zeichnet sich der IE 900 durch seinen Zusammenhalt aus… das gesamte Frequenzspektrum ist gut ausbalanciert, nichts, was es übertrieben oder vernachlässigt. Ihr Geld fließt in realistische natürliche Klangproduktion: Musik, wie sie ist.

Im Vergleich dazu sind meine geliebten Dunu Zen leichter anzutreiben…mit mehr Bass, daher auch schmaler, aber tiefer, stufenmäßig, mit einem viel schärferen oberen Mittelbereich. Ihre Becken verschwinden jedoch im Vergleich zum IE 900 in einem Loch. Die letzten E5000 sind schwieriger zu fahren, wärmer, haben einen volleren männlichen/weiblichen Gesang, sind Bassiser, aber der Bass ist im Allgemeinen fuzzier (je nach Quelle). Sie haben eine schmalere Stufe und es fehlt die Doppelverlängerung des IE 900.

Der IE 600 lassen sich etwas schwieriger antreiben als der IE 900. Sie sind bassigzer, druckvoller, V-förmiger und daher spektakulärer mit einer breiteren Massenanziehungskraft… aber sie sind auch etwas grober (insbesondere in den Höhen) als die feiner gewebte und bessere Bildgebung IE 900. Der IE 600 ist der überschwängliche Teenager und der IE 900 der reifere, entspanntere, ältere Bruder.

Der Sennheiser IE 200 ist schwieriger zu treiben als der IE 900 mit weicheren Noten, weniger intimen Bildern und ohne die spektakuläre Doppelverlängerung des IE 900. Sie sind dennoch insgesamt verdammt gut und produzieren zum Beispiel den Gesang sehr gut.

Abschließende Bemerkungen

Die Sennheiser IE 900 sind für Puristen, für Zuhörer, die Musik so nah wie möglich an der Wahrheit genießen wollen. Sie übertreiben nicht und begeistern daher nicht beim ersten Hören (abgesont der Doppel), sie verweilen … und tun es weiter. Die IE 900 sind eindeutig für den fortgeschrittenen Zuhörer, der tief in ziemlich komplexe Orchester-, Gesangs- und Jazzmusik eintaucht.

Der IE 900 mag teuer sein, aber er wird seine Relevanz und damit seinen Wert in den kommenden Jahren behalten. Ähnlich wie bei der vorherigen HD 600-Kopfhörerserie sind sie eine Investition in die Zukunft.

Bis zum nächsten Mal…keep on listening!

The $130 ddHiFi Janus3 is a Moondrop-tuned single-dynamic-driver earphone with an agreeable Harman sound and an original, small shell design that provides maximum comfort and fit. Adding the compact cable and the good isolation, it is a great companion for travel. Fits in your shirt pocket between flights.

The Janus3 was provided by ddHiFi for my review – and I thank them for that. You can get it from the ddHiFi Official Store.

Introduction

ddHiFi are a company that specializes in accessories such as adapters, cables, and storage cases. But they have also produced a line of earphones called “Janus”, after a Roman god that is often depicted by a double-faced head.

Reason for this name was the unique double connectivity of the two previous models, Janus1 (released in 2020) AND Janus2 (from 2021): both had sockets for 0.78 mm two pin and MMCX plugs. The E2023 Janus3 is therefore the third iteration of this model line.

The dual connector had the advantage that one could connect essentially any earphone cable found in their drawer….which was actually not necessary as each model featured a fancy and rather pricey cable you could also purchase separately. While the Janus1 lacked sub-bass, the Janus2 had an over energetic upper midrange. Both models also came with luxury cases…these accessories drove their price up to $200.

Moondrop helped out with the tuning of the Janus3, which is way more mainstream than that of their predecessors. Also slimming down the accessories helped reducing the price by $70. Interestingly, ddHiFi abandoned the 2-pin connector in the Janus3: you can only connect MMCX cables to this model. Strictly speaking, the Janus ist not a Janus anymore, as one half of its head is missing. But I’m waffling…

Specifications ddHiFi E2023 Janus3

Physical Things and Usability

Although slimmed down, accessory wise compared to its more expensive earlier iterations, you still find quite a few goodies in the box: most of all the gorgeous modular MMCX cable, that comes very close in appearance to the $60 ddHiFi M120 A model.

The wire is OCC (“Ohno Continuous Casting”), manufactured according to a Japanese process that results in essentially oxygen-free copper, which minimizes corrosion. The cable is thin, light, has the right stiffness, and essentially no microphonics. You can choose between a 3.5 mm and a 4.4 mm connector, both are included. There is no memory wire. All this is very handy.

Also in the box are a set of silicone eartips (S/M/L), the largest of which actually work for me. The storage case is not too small and very sturdy, also of good quality.

Finally, the earpieces, not double-faced as in the previous iterations, feature MMCX connectors. They are part metal, part resin, and you can look inside to admire the interior. These earpiece have otherwise not changed in shape: they remain small, light, they seal well, and can be worn over-ear or under-ear.

The Janus3 are easily driven with a phone.

Considering that many earpieces are marketed by their faceplates, which resulted in some monster cherries in our ears, ddHiFi’s pragmatic earpiece design may be one of the Janus’ biggest asset. Together with the light cable, you have a stereo that fits in the smallest pockets and isolates well in the loudest environments.

Tonality and Technicalities

The Janus3 features a classic agreeable, middle-of-the-road sound with a natural timbre and average technicalities without major flaws. In terms of richness, they are more on the lean side but without any stridence, which adds some articulation to the overall sound.

Although the shells are small, the drivers are reasonably large (10 mm, compare to Sennheiser IE900’s/IE 600’s 7 mm), and hence produce some decent heft at the low end. Sub-bass extension is excellent, an annoying midbass hump is missing, and the lower end can develop a good punch and impact…it all depends on insertion depth: deeper means thicker. A satisfying low end that is well layered, well composed, never too thick, and it does not smear into the lower mids either.

Female and male voices are therefore “free standing” and a bit on the lean however nuanced side. Lean does not mean thin, it means articulate and well carved out in this context. Upper midrange is not overenergetic. All this makes for a good midrange transparency: lots of space between notes and musicians.

Treble is subdued in its lower part but quite lively in the upper. This avoids shoutiness but adds (perceived) detail, sparkle, and liveliness to the upper registers such as cymbals. The treble is decently well resolving and articulate.

Soundstage is reasonably expansive and tall, with ok depth, imaging is pretty good. While layering, separation, and spatial cues are also decent (the stage is really well organized in 3D), detail resolution is average. Not bad, but not outstanding either. Timbre, as expected for a dynamic-driver earphone, is very good.

Concluding Remarks

The Janus3 is the sonically much improved version of the 2020/21 Janus1 and 2, with slimmed-down accessories, a better price, and a more cohesive, well-rounded sound. Its biggest assets are its original, imaginative small design with maximum comfort and fit, and its attractive modular cable.

While it does not add anything spectacularly new sonically for the experienced hobbyist, it may have its appeal to the novice and intermediate experienced…and/or to listeners who prefer to carry their stereo in a shirt pocket. Considering their good seal, the Janus3 are well suited for airplane, bus, or train travel. And that’s what I will use them for.

Until next time…keep on listening!

The post ddHiFi E2023 Janus3 Review – Beheaded God appeared first on Music For The Masses.

Very large part of the following article originally appeared as a section of my review of Sennheiser’s flagships IE900. We decided to spin it off as a separate piece to give it the just independence, considering how sensible the topic is.

Introduction to counterfeits and fakes

According to Cambridge dictionary:

Counterfeiting :- noun. UK  /ˈkaʊntəˌfɪtɪŋ / – The activity of making illegal copies of things such as bank notes, DVDs, or official documents.

https://dictionary.cambridge.org/it/dizionario/inglese/counterfeiting

… and, let me modestly add, “any other element of registered intellectual property” (e.g. patented goods).

It goes by itself that counterfeiting is a crime defined and punished by the penal code of pretty much all modern countries. Selling products of known counterfeited nature is, of course, consequently also a crime.

This is not unimportant to know, as when one realises to have been sold a counterfeited unit, she/he can leverage on the much higher power of criminal law to pursue the recovery of her/his interests vs the offending seller – with much higher chances of a positive outcome, of course, when such fraudulent seller is identifiable and locatable, and subject to the laws of the same country as the buyer.

Beware of counterfeiting!

The market is literally flooded with fake / counterfeited IE900, and IE600, and many other Sennheiser sets – and not since yesterday.

Sadly the criminals involved with this are quite skilled on delivering aesthetically near-identical products (from the boxing down to the actual items), thus posing a serious threat to the casual user when it comes to choosing and giving trust to their vendors, especially considering the important price tags we are talking about.

Sennheiser recommends to buy new units exclusively from fully trusted, official Sennheiser distributors – and that’s a no brainer.

For second hand units – while of course remembering that channels like ebay or similar need to be taken with two (always better than one) grains of salt – a good idea is to have the seller send a picture with the unit serial number in advance, and get in contact with Sennheiser Consumer Hearing support services: they will check if the serial number is reported as legit.

An illustrative example

I happen to have access to a fake IE900 sample, which I could therefore compare with a guaranteed-genuine one coming directly from Sennheiser’s headquarters.

Sound quality wise I must say I expected a much bigger difference between the two sets. What surprised me the most was in particular the fake unit’s remarkable bilateral extension, reasonably similar to the original one. In terms of bass definition, note body and microdynamics, however, genuine IE900 are quite evidently better.

Visual counterfeiting on the fake unit is really staggering for how realistic it is, and how much attention and careful observation was required to discover the clues indicating the two units did not come from the same ultimate source. I took a few pictures, and shared them with Sennheiser personnel to have confirmation of my findings, and here is my report – with the hope that it may be useful to someone to avoid being frauded.

First and foremost, there was no way to spot any difference whatsoever about the printed carton box sleeve, not on the box’s internal structure and elements, the paddings etc. All apparently identical.

By closely assessing product details however some differences started to come up.

1) Cables’ earhook sheaths are not freely reshapeable on the fake unit I checked – they stay much firmer on their pristine curvature for how much you try to model them. Genuine Sennheiser sheaths are pliable almost like plasteline, and they stay in your wanted shape quite reliably while you wear them.

2) Cables’ chin sliders feature a Sennheiser logo sticker. The genuine one carries an S-logo hologram, the counterfeit one is very obvious flattened, non-holographic, clumsy imitation. Genuine cable is sitting on top in the following picture.

3) Genuine cable’s main sheath features a smooth, uniform, solid external finish. This fake unit’s sheath carries some sort of twisted wires appearance. You can appreciate this difference, too, from the picture above – where, again, the counterfeit cable is the coiled one, below the genuine one.

4) Assessing nozzle ends, genuine IE900 should look “pitch black”, while this counterfeit sample reveals silver colour inside through a wider mesh structure, as shown by this picture.

5) The pinned plastic plate carrying stock tips should show glossy S M L size letters, not matte ones. Furthermore, genuine foam tips have quite flat tops, not bulging ones. Based on this information, try yourself to spot the genuine set in the following picture .

YMMV

It’s of course worth noting that I could assess just one fake unit, so there is no certainty, let alone guarantee, that the above hints do apply to other cases. So don’t take the above clues are indicative, let alone exhaustive, as a “check list” to apply to a suspect IE900 sample.

This article will have done its own right if I succeeded in just making you aware that there is an issue with this, and a serious one too – and you better spend a lot of time and attention to avoid being scammed. Good luck!

Gear of the Year: audioreviews.org is soon completing its 5th year. We are still six dedicated and competent authors located all over the western hemisphere, catering to a mature, discerning readership. Our list of earphone reviews is approaching 450 and our Wall of Excellence (WoE) is better decorated than the Christmas tree at NYC’s Rockefeller Center. Since any product on our WoE is backed by more than one opinion, it should give you confidence in your buying decisions.

However, our WoE is not a bunch of “best of” lists as we have not tested all competitors in each category. Such claims would be presumptuous.

We did, sadly, lose our single sponsor HifiGo (and some more suppliers) over our reviews of their gear. But hey, our critical, realistic approach sets us apart from 98% of the blogosphere (we think). We rather deal with companies that have confidence in their products.

Whatever gear passes our test must be somewhat good. We still don’t do Google ads, affiliate links, and we don’t allow trackers…we are no salespeople, we honour your reading pleasure and your privacy. We are simply audio aficionados.

Thank you for your patronage in 2023! Enjoy this read and we wish you a happy and successful 2024!

Hey, feel free to let us know your personal favourites of 2023 in the comments section below.

We thank our 2023 Partners

And here we go…that’s what we enjoyed in 2023…published by author in the order of submission…and purely subjective.

Loomis Johnson…Chicago, USA

Wiim Mini AirPlay 2 Wifi Streamer—the onboard DAC is just fair, and the app is quirky (if very ambitious), but through its digital out this is a genuinely excellent streamer  for less than a hundo.

BGVP DM9 IEM—energetic and massive sounding, these are head and shoulders above any other IEM I’ve heard this year. Richly priced at $600 and worth every penny.

Sony WH-1000XM5 Wireless Headphones—Bose has marginally better ANC and Sennheiser a longer battery and better UI, but overall the XM5 would be my pick if (god forbid) I could own only one TWS.

Oladance Wearable Stereo Open Ear Headphones —eons better than any bone-conduction model out there, these come close to good in-ear TWS models for sound quality, with a rich warm sound and a big 3D stage. Hall of Fame material.

SMSL D0400  DAC/Headphone Amp—a tad more detailed (if not necessarily better-sounding) than the godlike SU-9, the inclusion of balanced out and an excellent onboard headphone amp makes this my pick among SMSL’s myriad offerings.

Truthear Shio DAC/Dongle—well featured, balanced dongle won’t make your counterfeit Beats sound like Carnegie Hall, but it sounds just slightly more transparent than its ubiquitous price peers.

JBL Boombox 3 Portable Bluetooth Speaker— rather than spending ten grand to mod the sound system on his 100k pontoon boat, a very wealthy friend of mine dropped $349 on one of these. He couldn’t be happier. Link two together and you’ll be in hip-hop heaven.

Eagle Rare 10-Year Bourbon—if this was an IEM, we’d deem it “musical, balanced and fully coherent.” People are asking stupid prices for this in the secondary market, but if you can find it anywhere near its $40 SRP, buy it.

Dreamcloud Premier Rest Hybrid Mattress—the downside of buying a really good mattress is that it’ll sap your ambition faster than a meth habit. If, however, like me your ambition is to lay around and watch professional basketball, this is a necessary acquisition.

Jürgen Kraus…Calgary, CANADA

Short and sweet, as I am mainly still using my 2022 gear. And the best gear is the gear one uses after all. 2023 added a few excellent products to my daily listening. Oladance TWS Pro wearables were most impressive…and useful…a home theatre on your ears you don’t even feel. I can listen to these all day.

In terms of earphones, the Sennheiser IE 900 impressed me most because of their natural, cohesive presentation, their incredible treble quality, and their wonderful dosage across the frequency spectrum. I preferred them much more over the IE 600, which offer the same Harman type tuning we have experienced so often before. Both were sadly loaners. I also love the well-balanced Sennheiser IE 200, which are tuning wise closer to the IE 900 than to the IE 600.

Also very natural sounding are the Akoustyx S6, but they do need some modding to tame the upper midrange. As to budget TWS, I do have a pair of Moondrop Space Travel by my bedside, for talk radio and classical music. They have a very composed and nuanced presentation…and they fit me well.

Also by my bedside is the EarMan CH-Amp/Tradutto combination for driving my HD 600 and final Sonorous III. I equipped the HD 600 with a Hart Audio 4.4 mm balanced cable. Also great is the SMSL DO200 MKII DAC, which I use on my desk.

As a movable desktop stack (between sofa and kitchen table) serves the very good sounding Moondrop DiscDream CD player. A great idea to reconsider this technology — looking forward to another premium Walkman.

An honorouble mention goes to the very versatile TempoTec Serenade X Digital Desktop Player, and TempoTec as a company, as they don’t get lost in countless models of the same…no they offer one model of each product, and each is well thought out. A big step up for them in the last two years.

As a guilty pleasure, I indulged myself with USB cables for audio usage from AudioQuest (Forest), IKEA, and Monoprice. I love USB cables. And this combination of brands doesn’t leave room for the usual shitstorm by naysayers.

And hey, Loomis, we just acquired an Endy mattress. Made in Canada, of course.

Alberto Pittaluga…Bologna, ITALY

Given I’m not one of those world-famous tiktokers I guess it’s preliminary worth remembering that I have a sharp inclination to carefully avoid wasting time on even assessing “stuff” which doesn’t apriori seem to qualify for a serious upgrade to whatever I already own – an attitude of mine that applies across the board of course, not certainly to audio gear only. Such information is I presume key to better understand the following list.

Proceeding by categories, and starting with cans, towards the end of the year I got a pair of Sennheiser HD800. These were quite a lot anticipated to upgrade my pleasure on my particular library vs the HD600 – and that’s of course what happened. As a side bonus I had yet another chance to touch how important fresh pads and a decent cable are for sound optimisation, let alone how tough still is finding an overall more exquisite timbre then the one coming off my Groove.

Shrinking size down to IEMs, my trip to Munich earlier this year got me very curious about Sennheiser’s relatively recent IEM introductions, and that’s where the curiosity to assess IE900 and (from a different source) IE600 came up from.

The latter impressed me almost as much as the former, however when it comes to stunning V-shaped IEM encounters happened this year nothing beats – and I reckon will hardly beat tomorrow – Intime Sho DD.

The other major IEM acquisition of the year is represented by final B3, and their ability to capture the auditioner and port him onto the jazz stage. Honorable mention goes to Akoustykx S6 (and their “magic” Earlocks).

In terms of source gear, I completed my collection of DAPs by acquiring a Sony WM-1A, of course instantly flashing MrWalkman WM1Z signature onto it. For a number of reasons its sonic features are at the same time in line and complementary to those of my other standards: Questyle QP1R and QP2R.

Sometimes it does bring an audible improvement, other times it doesn’t – it depends on the apriori situation of the system you plug it onto. I’m talking about AudioQuest’s Jitterbug. My (quite articulated) home setup is clearly in the benefitted category, and that’s why 3 of these are now stable part of it.

Source gear honorable mention goes to a tiny-budgeted device, Ifi GO Link. That, and IEMs with a balanced cable and a 3.5mm TRRS adapter, right away became my blind buy rec to those individuals which every now and then, attracted by the gear they often see me fiddling with, ask me to indicate “something nice and inexpensive to get started with”.

Looking in retrospect what I just recapped (and I genuinely did it “live”, now, for the mere sake of putting these notes together) none of my 2023 preferred tech comes from chifi-land. The white-bearded badly-aging old continent nerd in me shily shruddered in realising it

Durwood…Chicago, USA

Kefine Klanar

Redefines what a planar can do, the Timeless 7Hz was great but it also had that overblown upper air treble that made it standout. The Klanar on the other hand dials everything down delivering similar quality bass and while not as treble exciting is better balanced, target curve crowd pleasing retaining the technical precision and quick transient delivery of the planar driver.

Moondrop Blessing Dusk 2 

Fits snugly staying in place, great technical details, with enough bass to keep me interested.

BGVP DM9

While I do not own many top tier earphones, I have listened to plenty at shows and know that they best anything I have in the $300 realm. The bass hump is well controlled and balanced nicely in the midbass/sub-bass transition region. The elevated treble plateau keeps them energized and engaging delivering maximum resolution and clarity.

SMSL DO400 DAC/AMP

Extreme value premium desktop DAC melding a powerful headphone amp. I miss the quick control of a potentiometer volume knob of a split dac/amp solution, but it is worth the feature rich resolving DAC and potent headphone amp drive.

Truthear SHIO DAC

Just as powerful as any of the dongles out there it sounds the most blended qualities of a dongle dac without leaning too warm, bassy, thin or sharp. Not head and shoulders above the LG G8, but can turn any USB-C phone into an excellent DAP for an average price.

Oladance OWS Sport

A new category of open-ear sports headphones that offers other uses while avoiding disadvantages of in-ear pressure, ear canal phobias, and isolation, earbud compromises, and over ears isolation and sweatiness. Balanced sound quality that trades low-end bass for open awareness without the lackluster bone conduction competition. Review coming soon, they know what they are doing.

TWS????

Still looking for a TWS all-rounder. I want them to fit tight without loosening slowly, excellent tonality and have good ANC. A blend of the Sony WF-1000XM3 ANC with the sound of the Moondrop Alice combined with the fitment of the KZ ZXS Pro.

When browsing the local classifieds this year I scored some very excellent sounding vintage ADS L570/2 and lesser known local midwest unicorn relic well tuned, amazing imaging cherry veneer Amrita Elan (I think) that my buddy is still scorning me over not “allowing” him to buy them instead- no worries we are still friends. He would love to get his hands on the 3 way model with isobaric woofers anyway.

Kazi Mahbub Mutakabbir…Munich, GERMANY

This year passed by in the blink of an eye, but fortunately I managed to listen to hundreds of devices in this rather short span. My personal collection also went through some radical changes, so without further ado…

Firstly, I finally upgraded my reference gear, both portable and desktop. On the portable side, it’s now Lotoo PAW Gold Touch paired with the venerable Cayin C9. The desktop, meanwhile, is the recently-retired Questyle CMA Twelve Master. Having tried numerous TOTL setups so far, these two fit my needs the most. I may add a tube amp down the line, but that’s for the future.

On the IEM side of things, my daily drivers include Sennheiser IE 900 and the (discontinued) Softears Turii. The IE 900 are perhaps the most advanced in terms of driver tech, and the Turii have such a unique, spacious sound that it belies the single dynamic setup. They have received the most “ear time” this year, and will likely continue to do so in the coming year.

On the TWS side of things, I am impressed by the Beats Studio Buds Plus. For once, a Beats product is actually decent enough to be a daily driver. Apart from the middling noise cancellation, there is little I’d change about them given the price tag.

Finally, I have streamlined my headphones collection and ended up purchasing a modded Sennheiser HD 800. These hold up tremendously well against the planar magnetic behemoths even now, and the staging and imaging are unparalleled in the sub-$2000 space. I was also pleasantly surprised by Sennheiser HD 660S2, though the price tag is a bit higher than I’d prefer.

This year, I finally managed to audition the Sennheiser HE-1 for almost an hour. It was a surreal experience and I can definitely see (or hear) why these are so mythical. That being said, the Warwick Acoustics Aperio are no slouch either and trade blows with the supreme Sennheisers.

But the one pair of headphones that I can call my “personal endgame” are none other than Warwick Bravura. They get dangerously close to the summit-fi behemoths and fortunately, come pre-built as a system so you can save on the cost of an energizer or accompanying pre-amps to further flavor the sound.

Notable mentions: Campfire Audio Supermoon (perhaps the best sounding planar IEMs), Softears Twilight (fantastic single DD), Effect Audio Code 23 (the best copper cable I have ever tried, despite the challenging ergonomics), iFi Go Blu (fantastic little dongle), Cayin RU7 (replaced Questyle M15 for my portable use).

Biodegraded…Vancouver, CANADA

Environmentally friendly, as his name implies, he stuck to his 2021 gear…again. Gives us carbon credits.

The post Gear Of The Year 2023 – Our Personal Favourites appeared first on Music For The Masses.

I can anticipate I had a very big pleasure in the encounter, and I hope I’ll be able to properly convey my take on the many pluses and few minuses of this set, together with some comparison hints with their lower cost (but not lower quality) sisters IE600 and more.

IE900 currently sell in Europe for € 1499.00 including VAT. Main official product page, with direct purchase possibility here.

Signature analysis

Tonality

IE900’s general tonality is bright-neutral. The timbre is slightly lean, especially in the mids, and you can tell from the very first audition that this is a product aimed at rendering trebles in the most organic, detailed, engaging at the same time non-distorting way as possible, while in the process never leaving bass less attended to. And – boy! – if they succeeded at this!

From a more tech-involved angle standpoint, what I also very interesting to note is that they chose not to closely follow, let alone chase, any most en vague target curves out there… More on this, maybe, much later on.

Sub-Bass

One of Sennheiser’s 7mm dynamic driver’s qualities – perhaps not the most important one, but the most readily apparent to me for sure – is its extension capabilities, something very hardly heard before on IEMs, at least from my modest hobbyist’s ears.

As a direct consequence of that bass reaches as deeeep as you can possibly hear. You can safely bet the limiting factor in this case is more your hearing than anything else.

In terms of volume some elevation is present, but a modest one at that. IE900 definitely are not made to satisfy so-called bassheads, not even “educated” ones. Even for the tastes of die hard acoustic jazz lovers like me, there are times when I concede to the pulsion to adding a +3dB low shelf at 50 Hz, but that’s really occasional: in most situations IE900 sub bass is just perfect for my (quite specialised – mind you!) library.

I’ll reach even further, actually, and I would say that although not so high in elevation it’s presence is anyhow so consistent and predictable that the net effect is similar to adding a subwoofer to your nearfield setup, keeping it at a modest sound pressure level, just for “background support”, so to say.

Mid Bass

IE900’s mid bass is fast, even sculpted, yet fully textured and very expressive, emotional. This is one of the sets that renders Andrew Cyrille’s kick drum with the highest level of realism I ever auditioned.

This weren’t enough IE900, and very particularly its bass line, scale incredibly well with amping power and quality.

While in general IE900’s sensitivity is not low, so as to make them driveable to already outstanding results by relatively modest powered mobile sources, you will be totally astonished by the difference – emerging particularly in the bass section – when driving them from high quality, much higher specced amp sources.

One inter alia: Cayin C9, which I happen to have access to. Mid bass and low bass notes come up in body, viscerality and slam in a totally surprising way. It all sounds (pun intended) as if you’re sitting in a mixing studios listening to on those high end monitors hanging in there. Really, really, REALLY significant. Oh and by the way: even in such “exalted” situation, mid bass never, ever takes over on the low mids…!

Mids

Mids feel slightly recessed, if nothing else because the other parts around them (bass, and most of all high mids and trebles) come across with even bolder personality, so to say.

On the other hand their general timbre is very good if a bit lean especially in the high part, yet feels spot-on in most if not really all cases for my library.

The passage from middle to high mids easily reminds me what happens on Final’s A3000 – another, much lower tier, single-DD set featuring a remarkable (within its price class) quality single dynamic driver. And, another virtuous example of totally surprising results based on a not so common, off-choir even, tuning curve.

The passage is very smooth, of course consequence of the one driver employed, and also of the sensible taming applied to the 2-4Khz region which, thanks to driver elasticity (and, in IE900’s case, of who knows what other aspects liaised to the triple resonance chamber milled into their housings – more on this below), does not translate into overly tamed feedback in that region, oppositely it delivers a very lively, detailed while unoffensive experience.

As I mentioned before, if one remark the high mids segment calls for is some relative leanness to the notes. I feel some “butter” missing on central piano octaves, and on female vocals, to match my personal perfection. I’m not of course expecting to find the same focus on that region here that you can get from specialised sets like Final F7200 to just name one, yet as I said just a tad more of lipids would have rendered the dish even more flavoury.

Male Vocals

IE900 render baritones and bass humans with organicity and authority, and tenors, too, with just a bit of relative leanness commencing to appear on their higher registers.

Female Vocals

Female vocals are well presented, textured, clean and quite engaging. As mentioned above, they do lack a bit of body to their central notes to be astonishing.

Highs

These, together with some of the technicalities, are evidently the stars of the show on IE900.

The result is so outstanding that you can bet this must be the consequence of something really special the developers had to put in to get there: energy, expression, body, details and air, all together, while never scanting into sibilance, shoutyness let alone zinging.

A wonderful litmus paper test for this is Lee Morgan’s trumpet phrasings from 1 up to to 2 minutes into Art Blakey’s & The Messenger’s monumental 1958 Moanin’ take, from the homonymous album. Morgan instrument’s sound is full bodied yet perfectly textured, but most of all powerful yet not piercing, and far from splashy or shouty.

Such result does vary a bit in accuracy depending on eartips selection (more on this below).

Incidentally, I could only hear one other set doing better to date, but it did so only on this very particular aspect and failed in others in comparison to IE900, bass being first: a German-made multidriver unit. Oh and that’s priced 3X over our today’s reference .

Technicalities

Soundstage

IE900 stage projection is probably the widest I ever heard in an IEM, and while I think about that I would also put all closed-back overears I heard in, for good measure. There’s significant height and good depth, too !

This is another situation where IE900’s huge treble extension shows its good deeds: as many know of course we can hear sounds up to 16Khz (well… when young! ) but frequencies above such mark are not useless at all, as they contribute carrying information about the time it takes for sound to come back (or not come back) from the “walls around the room” – thereby helping on “drawing the stage”.

This is of course only evident when the source digital material does contain such higher frequency information, and the DAC is indeed capable of reconstructing it – which is luckily the case for much of my library, and a few of my sources .

Imaging

Macrodynamics are extremely precise, positioning cues are spot on at all times, along all 3 axes.

Details

Detail retrieval from the high mids and especially from the treble is nothing short than superb, twice as much if again we remember we are in presence of a single DD set.

I like to believe this is one consequence of those Sennheiser’s claimed designs efforts focused on sound modelling obtained via those cavities inside the housings (more on this below).

Let me add that, as an old western-economy industry bear myself, I also like to think that in addition to the positivity on the obtained result this way of proceeding is also much less prone to be “easily replied” by of some of those chifi usual suspects – building practical reproduction hurdles into one’s physical product arguably representing an even more effective method, supplemental to “mere” legal patenting, to better protect one’s industrial invention efforts in our globalised world lacking cohesive governance.

Instrument separation

Layering and instrument separation is another field where IE900 surely excel, once again especially so when considering we are talking about a single driver set.

Even on busiest (acoustic) tracks you never get a sense of congestion or mixture between voicings coming from the same spot on the stage, and the sense of depth is always granted. At times, it seems as if IE900 are able to render virtually infinite layers, such is their capability in keeping overlapping but heterogenous sounds apart from one another.

I could only hear one other IEM set till now able – on equal source gear and tracks, of course – to present me with a superior readability on low volume and/or background sounds, and that’s Softears Turii – which other technicalities, and the tonality before them, are however quite different from IE900’s so I wouldn’t easily cast a better/worse score between the two, frankly.

Driveability

As en passant I previously mentioned, IE900 are quite easy to drive exploiting the power of so many at least decent mobile sources on the mainstream market, most dongles included. Their 123dB/V (corresponding to approx 105dB/mW) at 18 ohm are not a huge requirement in facts, and that’s surely a big plus in terms of crowd accessibility.

On the other hand, IE900’s note body will dramatically improve when the source happens to have the guts to push up on current delivery, this with particular regards to mid bass and mid tones.

While listening to IE900 directly paired to a Lotoo Paw Gold Touch DAP is already a lushy treat – for many reasons, first and foremost LPGT’s quite special proweness on subtle microdynamics reconstruction – you should wait until you’ll hear what you get having LPGT’s output pass through a further amplification stage, e.g. a Cayin C9 mobile set: then you’ll be in for a strong experience … .

Such situation can, and should, be reported both as a pro and as a (relative) limitation of the set.

Physicals

Build

I suspect not to be the only one whose first eye-impression when shown a pair of IE900 has been something like: “inconspicuous”.

Actually handling them such impression – well, at least my impression – changed radically: IE900’s housing are in facts CNC-milled off a solid piece of aluminium, which incidentally is a wonderful material I happen to know the positive properties of due to my professional involvement with it, on a completely different market.

Long story short, IE900’s housings are at the same time extremely solid and sturdy, and very lightweight.

I also do approve the choice for those thin engraving lines on the outside, which – if anything on the aesthetical level – result in a pleasant, if a bit mitteleuropean-industry-flavoured, “unglossy” finish style, and avoid overexposure to fingerprinting.

On the solidity and shock resistance there’s no question: a solid piece of aluminium gives more than the required warranties for this use case. I’m ready to bet that trampling over these ones (with their cable removed) with a car would leave them a bit dirty, but in shape.

Apart from all this, what is surely most interesting is what cannot be appreciated from the outside, and that is the internal shaping given to the housings – always by CNC-milling them – and the specially developed ultrawide range-capable 7mm dynamic driver.

The DD is responsible for offering coverage for an exceptionally wide range of frequencies for a single driver: from 5 to 48KHz.

That being not enough, taken alone, to deliver the wanted sonic result, tonality shaping is carried out by way of tree small resonator chambers, i.e. appropriate “carvings” milled into the very piece of solid AL making the housings, in-between the driver and the nozzle. Furthermore, some specialty shaping and internal surfaces finishing is put in there, to take care of smoothening excessive treble energy – and I must say with excellent results, based on my audition (see above).

Fit

Kudos to Sennheiser also for the just incredibly effective ergonomics they conceived for the shape of their IE series, which includes IE900 of course.

Even if for some reason you wouldn’t tell when seeing that somehow uncommon form for the first time, it takes seconds after wearing (any of) them the first time to vibrantly love them, and the one(s) who designed them.

On the flip – read negative – side two things are worth noting.

One: in some cases – me included – the main housing body may be a (decisive) tad too lean to match those magical proportions which fill your outer ear just enough to gain perfectly stable positioning while never feel like a swollen bean is nagging at you from out there.

It’s of course then evident that you can’t possibly design a one-size solid structure that’s so precisely fitting into everybody’s body, no matter human diversity. And in doubt, of course you’ll have to do it smaller vs bigger ! So this ain’t defect of course, yet it’s definitely an issue to manage, when it arises.

Two: again, in my case, the supply of stock tips (both silicon and foam) for one reason or the other falls short of being adequate.

Stock silicon tips have a very soft umbrella, 100% studied to get the best intended sound out of the IE900. Too bad that on the “mechanical” front it happens that, housings being too lean to stay put in my concha’s, I instinctually tend to regain firmness by pushing them deeper in. When that happens silicon tips’ umbrellas fold on themselves, totally losing the seal.

Sadly, the problem about stock tips falling short of properly fitting my canals (left one in particular) affects foamies too! Again, I suspect that’s liaised with me needing to get a higher stability by pushing shells deeper in, thereby reaching a wider segment of my ear canal, which those foamies can’t adequately fill up, not even the supplied L size.

I shared this issue with Sennheiser, and the answer has been enlightening for the sake of clarifying the origins of this situation.

First and foremost, in Sennheiser’s design intention IE900 tips should ideally “feel as if they disappear” in the ear canal, precisely the opposite of the sensation you get from bullet style IEMs, and/or triple-flanged eartips. Hence, the thinner umbrella the better, of course.

Flipping the coin, however, superlight tips intended for such precise aim will not be the best choice if for whatever reason a user prefers, or needs, to achieve a deeper fit.

I do confirm all : if – disregarding stability for a moment – I wear IE900 in a shallower position, indeed their stock silicon tips do keep the seal, and they deliver a very pleasant “feathery” sensation, or even virtually no sensation at all – as per intention.

And by the way, were it possible and handy for me, I would actually prefer such shallow fit, not being myself a die-hard fan of deep insertion – even when I use bullet-shape IEMs (which nevertheless – Sennheiser friends will forgive me – I don’t find so devilish counter-ergonomic as they reckon).

Be as it may, this finally reveals what the entire real problem is in my case: housings’ stability.

Again, in Sennheiser’s design intention, in cases like mine where the person’s ear structure is a bit too big and can’t grab the housings firm by itself, that’s where those easy-shape earhook sheaths installed on the cable (more on them below, under “Cable”) should do the trick, mechanically retrofitting the set so to say, and delivering the required stability.

So that is precisely where the game fails in my case (and not my one only).

No, to me those shapeable earhooks are super-comfortable, but not resilient enough to compensate for the housings’ eventual wobbling. That’s why I can’t personally “afford” a shallow fit, and rest comes with it.

Curtain fall ? Nevah !

First possible workaround: browsing the internet I found some sort of third party “gel outfits” – of course made some place in China. I call them “gloves”: imagine little-finger sized equivalents to a silicon smartphone back-cover. Or, similar to those winged rings you fit onto TWS drivers to help them stay firm in place. Something like this, but there are others around too.

I tried a friend’s ones and indeed those perfectly fit IE900’s housings, granting them that small body size increment that results into fitting my ear in a perfectly stable and comfortable way. And then, yes!, I can afford shallower fit and the whole stock tips game works as per design in my case too.

Alternative workaround: use third party tips .

Well as you can imagine I would have gone through the long tips exploration session anyhow, but in this case it was let’s say double motivated.

This article is getting already lengthy and I don’t believe that adding further smalltalk to it would make it better so my eighteen readers will I hope understand if I won’t indulge in the full report here about how I found each of the probably 15 different tip models I tried.

Suffice it to say that in the end I’m torn between two options, featuring some differences : INAIRS AIR1 foams, and JVC SpiralDot silicons.

INAIRS offer a firmer fit sensation, and their M size actually well fills my external ear canal up, thereby effectively contributing to hold those slim housings firm(er) in place for me. They also grant me better passive isolation, and a sort of delicate “softening” to some note edges (which, in itself, is not always a welcome addition).

SpiralDots feature stiffer silicon umbrellas compared to stock tips but won’t go as far as mechanically compensating housings movements, so their adoption does require either a deeper fit, or those “gel gloves” I mentioned before. The good news is that they are sturdy enough not to lose the seal when pushed deeper. Their wide bore positively contributes to IE900’s already good bass, and they yield a more crystalline timbre compared to foams.

Runnerup silicon options worth mentioning are Radius Deepmount – even better than Spiraldot on bass definition and speed, but tend to turn trebles a bit too hot – and Final E (strictly CLEAR version – black and other-coloured ones making low bass a bit “hazy”) – which deliver more body in the mids but lose some detail and precision in the treble and bass.

Last but absolutely not least, Sennheiser and their mother company being deeply involved with medical grade hearing aids and technologies, a custom eartips production service is made available – sadly only to German residents for now though .

It’s called Custom Comfort Tips. The rationale seems very simple in its complexity: by realising an elongated silicon tip, custom shaped following your own ear canal shape and size on one end, and perfectly slapping onto the IEM’s nozzles and neighbouring shell part on the other, you get extremely close to eliminate that personal fit variation that makes each one’s sound experience with that particular driver too much “potentially different” from its intended goal.

The program is also very well streamlined in terms of enduser fruition. It’s all centrally managed by Sennheiser, you don’t have to “look for” anything your own: place the order centrally, geoloc the supporting audiologist shop nearest to your location from a link on Sennheiser’s site, take an appointment and have your canals measured there (their service is part of the price paid to Sennheiser), wait for a few days and receive your tips at home.

The very same tips can be swapped onto IE900, IE600 and IE200. The tips’ fee is currently included with the price of an IE900 package, and a discount is offered to IE600 owners.

Those friends (lucky bastards individuals) who, residing in Germany, already could get their custom tips confirm they are indeed absolute game changers. The rest of us need to come to terms with a impatient wait .

Comfort

IE900’s shape is designed for very easy and natural fit and this immediately traduces into supreme comfort even for very protracted period of time.

In case the housing turns out to be a bit too “slim” for one’s ears (like in my case) there’s a chance the consequent instability may be somewhat fastidious. Longer story above about the origins of this. Consequences: compensating instability by reaching down for a deeper fit may turn out to be a bit uncomfy in medium/long sessions; adopting “gel gloves” of appropriate thickness may be the best way to go.

Isolation

When perfectly fitting, IE900 offer good levels of passive isolation – even more if equipped with foam tips.

In “fat concha” situations like my case, the same result is quite easily obtained by outfitting the housings with with “gel gloves” or such (see above).

Cable

It’s certainly pleasing – if after all in line with expectations vis-a-vis the package price, one may say – to find 3 different cables inside the box, each with a different hard-wired termination: single ended 3.5mm, and balanced 2.5 and 4.4mm, covering I would say 99.9% of possible needs.

Also, the freely mouldable TPU sheath applied towards to cables housing’s end allows you to shape them into the most precisely matching and comfortable earhooks you can get, exactly following your ear root line.

It’s the first time I encounter this offering, and it’s a very welcome feat – even if, as reported under “Fit” here above, it does not get as far as solving the problem of housings being too lean for my particular outer ears.

On another important note: Sennheiser’s IE-line MMCX connectors are not “everyday MMCX” fixings in reality. So be prepared: hardly any of your (my!) existing MMCX cables will fit, or safely fit .

Sennheiser’s MMCX implementation (in some documents tagged as “MMCX Fidelity+”) is indeed proprietary. Looking closely, the male connector coming off the tip of the cable has an additional “lip” compared to ordinary MMCX plugs. Such lip, plus a deeper, and more deeply recessed female connector, are responsible for significantly improving on connection firmness.

All good so far, the less good news however being the following two.

One I already mentioned: 99% chances are that you won’t be able to pair your IE900 with any loved individual off your thick existing herd of however good – and expensive! – MMCX cables.

The other is safely identifying the genuinely licensed (!) third parties, which would therefore be in condition to supply reliably compatible cables. Fact: between a few friends of mine and myself we experienced a few 3rd party cables sold as IE900-compatible, most of which turned into wobbly, unreliable connections. Tread lightly when shopping for cables here!!

Comparisons

Sennheiser IE600 (€ 799,00 – currently on sale for € 549,00)

Even if very similar aesthetically, and equally based on a single dynamic driver, IE600 and IE900 are quite different at the technological level from one another.

Sennheiser confirmed to me that the dynamic driver inside IE600 is a different variation (although part of the same main project) from that adopted for IE900. The same applies for the driver inside IE200, by the way.

In addition to that, housings’ builds and their internals are also quite different.

Unlike IE900’s earpieces – CNC-milled from a solid piece of aluminium and featured with 3 specially designed resonance chambers inside – IE600’s housings are 3D-printed from a special zirconium alloy by Heraeus Amloy Tech, and featured with two sets of 2 internal chambers. Such structure internal to IE600 (D2CA: Dual 2-Chamber Absorbers) focuses on treating overlapping notes coming for different instruments at the same time, helping on dramatically improving they separation, and layering.

With all this said, the sound experience offered by IE600 is for some respects similar, for others quite different from that granted by IE900.

Similarities stay in rendering clarity, and in outstanding layering and separation proweness.

The main difference is in the tonality : unlike IE900, IE600 are quite evidently V-shaped, although maybe a “wide V” at that. A more mainstream indulging tuning choice if you wish, vs IE900’s off the choir one.

Bass is equivalently speedy on IE600 and IE900, but on IE600 it is much more evident, elevated, and I refer to mid bass and even more to sub bass here. In spite of such higher elevation, bass is still perfectly readable at all times, very well textured, and stays consistently separated from low and central mids – as it definitely should – in IE600 no less than in IE900.

Another part where the two sets diverge is in the high mids, and – I would say al least in part consequently – in their treble.

IE600’s 2-4K frequencies are way more forward and pulpy, with this bringing guitars and female vocals the “butter” which is a bit left behind on IE900. However an important taming is imposed on 6KHz on IE600, I assume to avoid that their composite output would scant into shouty and/or fatiguing. As a consequence, treble detail retrieval and overall “airiness” is quite obviously less on IE600 vs IE900.

Quitting all this tech talk : choose IE600 for prog rock, hard rock, electronic music and general purpose, while – money not being a hurdle – go blind-eyed with IE900 for acoustic jazz and most of all classical music.

Such separated applicative indications, paired with ultimately equivalent proweness in doing, each one, what they are designed to do, calls for refraining from positioning IE600 and IE900 one on a higher step vs the other, and I rather recommend them as different tools to reach different pleasures, so indeed complementary to each other.

Campfire Andromeda 2020 (discontinued, was € 1099,00)

I feel this is a quite interesting comparison not only due to the reputation Campfire Audio as a manufacturer, and the various iterations of their Andromeda set deservedly conquered over time, but especially vis-a-vis the under many respects opposite design philosophies behind Andromeda and IE900.

As everybody may remember, Andromeda are a full-BA multidriver sets, vs IE900 single-DD choice.

As a further testimony to the successful results obtained by Sennheiser on their sole dynamic driver, I would readily note that if one of the two sets may be found to deliver a tad less bilateral extension that is… Andromeda. Differences on this are small, however.

Other aspects which are very similar between Andromeda and IE900 include treble detailing, and the tuning choice to keep their 2-4KHz regions tamed down to help deliver a smooth, unshouty yet energetic overall highmid+treble section, which is indeed the case on both sets, and probable the key reasons why treble is equally delicious – beyond within some differences – in either situation.

Other similarities, or real equivalences are about stage size and three-dimensionality, with Andromeda being probably a tad deeper but less high and wide, and about layering and separation.

Tonalities are instead quite different: Andromeda is obviously warmer, consequence of some more power impressed onto 2-400Hz and some taken off from 1-2Khz. IE900 offer more airiness up above, not much resulting in terms of better clarity but rather in terms of a more realistic spatial sensation.

The most obvious differences however stay on bass note body and microdynamics: Sennheiser’s model attains to a higher level altogether, especially on the latter part – IE900 microdynamics are a very thick step above Andromeda.

As for driveability Andromeda require much less power to shine at its full potential, but conversely they require so little of that, and at such a low impedance, that many if not most sources will make them hiss, and that will of course be audible through quiet musical passages.

Beware of counterfeiting !

It is sadly worth noting that the market is literally flooded with fake / counterfeited IE900, and IE600, and many other Sennheiser sets – and not since yesterday.

Sadly the criminals involved with this are quite skilled on delivering aesthetically near-identical products (from the boxing down to the actual items), thus posing a serious threat to the casual user when it comes to choosing and giving trust to their vendors, especially considering the important price tags we are talking about.

I happen to have access to a fake IE900 sample, which I could therefore compare with the guaranteed-genuine one coming directly from Sennheiser’s headquarters.

Sound quality wise I must say I expected a much bigger difference between the two sets. What surprised me the most was in particular the fake unit’s remarkable bilateral extension, roughly in the same ballpark as the genuine one – and that’s saying something. In terms of bass definition, note body and microdynamics, however, genuine IE900 are just straight better.

Visual counterfaiting is really staggering for how realistic it is, and how much attention and careful observation was required to discover the clues indicating the two units did not come from the same ultimate source. I took a few pictures, and shared them with Sennheiser personnel to have confirmation of my findings, and here is my report, with the hope that it might be useful to someone to avoid being frauded.

First and foremost, there was no way to spot any difference whatsoever about the printed carton box sleeve, not on the box’s internal structure and elements, the paddings etc. All apparently identical.

By closely assessing product details however some differences started to come up.

1) Cables’ earhook sheaths are not freely reshapeable on the fake unit I checked – they stay much firmer on their pristine curvature for how much you try to model them. Genuine Sennheiser sheaths are pliable almost like plasteline, and they stay in your wanted shape quite reliably while you wear them.

2) Cables’ chin sliders feature a Sennheiser logo sticker. The genuine one carries an S-logo hologram, the counterfeit one is a very obvious flattened, non-holographic, clumsy imitation. Genuine cable is sitting on top in the following picture.

3) Genuine cable’s main sheath features a smooth, uniform, solid external finish. This fake unit’s sheath carries some sort of twisted wires appearance. You can appreciate this difference, too, from the picture above – where, again, the counterfeit cable is the coiled one, below the genuine one.

4) Assessing nozzle ends, genuine IE900 should look “pitch black”, while this counterfeit sample reveals silver colour inside through a wider mesh structure, as shown by this picture.

5) The pinned plastic plate carrying stock tips should show glossy S M L size letters, not matte ones. Furthermore, genuine foam tips have quite flat tops, not bulging ones. Based on this information, try yourself to spot the genuine set in the following picture .

It’s of course worth noting that I could assess just one fake unit, so there is no certainty, let alone guarantee, that the above hints do apply to other cases.

Sennheiser recommends to buy new units exclusively from fully trusted, official Sennheiser distributors – and that’s a no brainer.

For second hand units – while of course remembering that channels like ebay or similar need to be taken with two grains of salt (always better than one) – a good idea is to have the seller send a picture showing the unit serial number in advance, and get in contact with Sennheiser Consumer Hearing support services: they will check if the number is reported as legit.

Considerations & conclusions

I tried to outline the multiple reasons why I believe IE900 are a beyond-outstanding product, particularly suitable for classical, and acoustic music in general, and I feel like adding some considerations at a more general level here.

What is seems from the outside is that Sennheiser did this by going back to the design board, and restart from assessing the wanted target, asking themselves how to reach it – “reinventing the wheel” if need be, and/or using more “usual” parts and competences, purging their minds from “assumed-well-established existing solutions” bias in advance.

Of course I have no real clue about their internal processes and how the real story went, but if it were a plot for a movie about an industrial success story, it might probably go as follows.

IE900’s dynamic driver itself is proprietary, made to deliver a sensibly wider range extension compared to other high quality dynamic drivers on the market. Why? Because multidrivers do struggle with tonal coherence – all of them – and, let’s face it, for good reasons too. On the other hand, existing single drivers are all “short blankets”, so to say.

So point #1 : let’s design a “wiiiiiide blanket” driver. Period. Then we see the rest.

Oh by the way: let’s do it without employing marketing-buzzword-level raw materials.

IE900’s is in the end a plastic membrane driver – such an “obsolete sounding” technology, inn’it? – yet it loops dozens of circles around others made of “newer materials”. Guess why?… .

I must say I feel empathic on these topics as they can’t fail reminding me that within the infinitely more modest scope of the small industrial company I currently serve in as a marketing and sales manager I often listen to my agents recursively pointing at certain innovative-name-sounding products from the competition. Transeat. Back to our plot.

Once you have an eXtra Wide Range transducer, you are still supposed to shape its sound to manage its behaviour, avoid excesses, and bend its tonality to a specific wanted target sound. This is usually done by a mix of shaping IEM shells, adding vents, filters, foams, meshes etc.

As for us: we will primarily “shape the shells” – and good luck to those who will try to precisely copy them.

Inside IEx00 housings there are milled or built (depending on the specific model’s production process) micrometrically formed spaces (“chambers”). They even got as far as studying how wrinkled their internal surfaces need to be to get the right wanted effect on sound waves passing by.

I can only remotely fathom the complexity of such a research, and the level of competences, skills, tools and budgets (!) you need to put on the table to even commence spinning such a project up. Well they did it – and succeeded.

Last but not least: once you have those grand IEMs done, based on a superbly extended driver, and tuned to consistently output the exact wanted timbre and tonality onto… lab measuring equipment (!) how about maximising the chance the same or at least a very similar result is actually appreciated by anybody’s ears – which sadly (for engineers, and luckily for philosophers) are all “guaranteed different” from the most advanced acoustic coupler mockups employed at the lab ?

Yes, you can try closing the gap by filling the commercial package with countless alternative eartips, or…

Our mother company is a leading multinational involved in hearing aids and acoustic implantations. Let’s roll out a custom eartips program!

I presume this very long stream of considerations, and their fictionalized dressings, can be summarised as follows: the old saying “when the game gets tough, the tough get playing” is of course in general an abstraction – it does take for the tough to actually be willing to get playing ! But when they do… .

Sennheiser for decades did deliver undisputed top-class headphone models (do we need to remember that HD600 originally came out in 1997?) yet they flew much lower in the rankings of IEM proposals until recently.

With their IE900 / IE600 / IE200 program they took a wholly-renovated approach to the segment, and results do show.

These 3 models lead their corresponding price brackets, and debating whether they deserve #1, #2 or #3 entry in their specific subclasses is surely very important for Sennheiser’s product marketing, their numbers etc, but for us, the users, it’s now probably just funny, loud coffee bar discussions. IE200, IE600 and IE900 are, all of them, absolute winners, and each one can easily be taken as the sole IEM one may want to own given that budget and/or that musical preference.

IE900 are light years far from being yet-another high quality high priced single DD IEMs. They can and should be narrated as a successful reinvention of the entire IEM experience, instanced onto the specific preferences of classical and other acoustic music lovers.

Sennheiser created a monumental product with IE900, and while its price tag is no doubt demanding, not a cent of it lacks justification in the multifaceted quality it offers.

IE900 is dutifully tagged on our Wall of Excellence.
