The ddHiFi Carrying Case C2023 is yet another well-made textile-leather carrying case for your personal audio gear.

The ddHiFi C2023 was provided by the company upon my request – and I thank them for that. You can get it for $57 from ddHiFi.

Introduction

ddHiFi are a Chinese company that impressed us with high-quality adapters, cables, earphones, dongles, and other accessories – which promoted them collectively to our Wall of Excellence. The company started adding a series of bags and cases 3 years ago with the C2020, a storage wallet for headphone DACs, amps, and other accessories. The C2020 is useful for travel and lives mostly inside a bag or suitcase. The subsequent C2022 was a true on-the-go shoulder bag with the dimensions of a small camera bag.

The new C2023 is another compact shoulder bag with different dimensions and functionality compared to the C2022. It is not an upgrade or replacement but rather a parallel development and a complementary design.

Specifications

Physicalities

The C2023 carrying case, like the C2022, is largely made of double-strand nylon on the outside, with cowhide leather at the bottom and in the front. Critical areas of the bag are padded with sponge material.

The inner lining is of polyester. It comes with a shoulder strap that is also made of sturdy nylon and adjustable in length. It is plenty long for a 6 ft/180 cm guy like me. The straps are of very good quality and so are the zippers.

Features and Functionality

The ddHifi C2023 case is a rather tall and slim bag that can be worn in different ways along the body. Since its compartmentalization is impossible to photograph, I present its layout schematically.

• Green: zippered and padded front pouch for small items: iems, change, bus passes etc.
• Red: the padded main compartment for your DAP, DAC, phone or similar. It features two interior pockets and a keychain.
• Black: a back pouch that can be expanded via a zipper (compare to some carry-on luggage for air travel). It is open towards the top. The pouch can hold a 0.5 l water bottle or a small umbrella, for example.

How to wear

Wear the C2023 like shown in the two images below or without a shoulder strap…just attach it with a carabiner to your belt or backpack. The bag features lots of hooks and D-rings for various configurations.

Comparison C2023 and C2022

C2023 and C2022 differ in shape and functionality, but not in materials. The C2022 is noticeably stubbier and thicker, the C2023 is taller and slimmer. With its 4 compartments, the C2022 holds more gear, but the C2023 holds taller devices – and it sits just better along the body….I find the C2023 ergonomically more appealing.

The C2023 also features some improvements such as the advanced shoulder strap.

When actually using the C2023 bag on a daily basis, I find it more comfortable than the C2022. I also like the idea of the expandable pouch. The C2022 may be not as ergonomic, but it holds more gear.

Concluding Remarks

ddHiFi extends their line of high-quality storage devices with the C2023. Although it serves a slightly different purpose than the bulkier, roomier C2022, I find the smaller but taller C2023 more comfortable to wear. From a material or quality perspective, both are identical. In the end, both bags complement each other.

Until next time…keep on listening!

The ddHiFi MFi09S is a 10/50 cm long Lightning to USB-C cable claimed to make an obvious sonic difference. This article also generally addresses the contentious issue of sound improvement by digital cables.

Introduction

ddHiFi have been one of the most innovative companies for portable audio. They produce functional, imaginative, high quality accessories, from bags, through cables to adapters, and even a couple of earphones. Their latest endeavour is the Nyx series of audiophile digital cables, which are all share the same wire material and insulation: a USB-B to USB-A, a USB-C to USB-C, a Ligthning to USB-A and a Lightning to USB-C for connecting iPhones to a DAC.

Therefore, today we are…no, that was already last week. And its only me once again. Therefore, in this article, I examine the ddHifi MFi09S Lightning to USB-C, mainly for its sonic capabilities. There are many crying “snake oil” now (and pull out some questionable measurements in their support), but whining is one thing, and listening is another. As we will see, the situation is not as black and white as it seems.

This article also has another purpose: to summarize our current knowledge of digital data transfer in layman’s terms. Although this is presented rather compact, you may want to re-visite this article for the occasional refresher.

Specifications MFi9S

Physical Things/Technology

You have seen the materials used in the specs above. Power line and data line are made with different wires that are well shielded against each other. The connectors are rather large, therefore easy to grip, and they are very rugged. These plugs fit even the smallest phone case. The cable as such feels substantial but it is a bit stiff, which works better for the shorter 10 cm version. You find technical details on ddHiFi’s USB-data cables product page. Overall, this cable is haptically and visually very attractive.

The MFi09’s lightning connector features a decoding chip which draws a small current from the phone. I did not test this one specifically, but all other non-Apple lightning cables previously in my hands have the same power consumption, as tested here.

Company Claims

ddHifi claims that the MFi09S offers a “noticeable sound quality improvement“. They fail to specify over what the improvement would be (maybe their own MFi06 cable?, but it appears obvious that it must be any other such cable.

Physical Theory

Noise and Timing

So what sonic improvement (over what?) can we expect in a digital cable? After all, it transports zeros and ones, right (which are transmitted as voltage fluctuations)? Actually, it carries data and power in two separate lines.

Principally, there is lots of “digital crap” coming out of a phone: jitter (timing errors) and noise. That’s because a phone is not a dedicated music player. I has no proper audio clock and lots of other functionalities that require different electrical components, which are cramped in a small case and affect the outgoing digital signal negatively, mainly by electromagnetic interference (EMI), radio frequency interference (RFI), and timing errors (jitter). In some cases, interference is caused by the client DAC, as demonstrated on the example of the EarMen Sparrow by Biodegraded. And noise can also be produced inside the cable (through poor insulation).

What’s in a Digital Cable?

Fact is, there is no difference in incoming vs. received data between expensive and budget cables, bits are bits, and the result is “bit perfect” in every case. So, no sonic difference, right? Stop, we have to examine what’s in a bit: jitter, timing, and noise. Jitter and timing can be measured (and corrected for by re-clocking), which leaves us with noise. It is a bit of an unlucky choice of words, I’d call it impurities superimposed on the digital signal which may (or not) degenerate the sound.

A metallic digital cable is principally a conductor that also transports pre-existing noise (it cannot distinguish between the good and bad things in the data stream) but it is also an “antenna” for near-ambient RFI/EMI, and it generates its own stray/spare magnetic and electrical fields (when carrying a constant current).

So what can go wrong during digital data transfer? When signal voltage is transported, the host and the cable may pick up stray signals in addition to the intended one…just like dirt being added to the bathwater. In addition, host, cable, and client can be on different “electrical” ground levels. Third, interferences during transport may generate time delays.

Timing errors need filtering by decrappifiers such as the ifi Nano iUSB 3.0 and re-clocking, typically not done in the phone host but in the DAC client at the other end of the digital cable. EMI can be minimized or avoided by the use of high-quality, well-shielded electronic components in the phone – and by a good digital cable.

In a well-designed cable, data line and power lines are separated and well shielded from each other (and from outside electromagnetic interference from, let’s say, power supplies), and it is twisted to minimize the contact areas between the two. Material also plays a role for data integrity: for example, in networks, fibre optic cables are not susceptible to EMI, copper is. EMI is important not only for the design of cables, but also for the electronics and the circuit board.

In summary, noise contamination happens in the source and/or during transport through the digital cable. The old rule “garbage in, garbage out” is also valid for digital data. If the data stream leaving the phone is compromised, the cable cannot fix it. All it can do is not let it further deteriorate. It cannot reclock or filter, and therefore not correct for the phone’s EMI/RFI and/or jitter.

Therefore, if the source emits a noisy signal, even the best cable makes no difference, but a bad cable further deteriorates the signal. If the host signal is clean, cables may make a difference. A dedicated music player may generate a cleaner data stream than a computer or a phone.

What Others say

The Audiophiliac Steve Guttenberg compared “fancy” optical and coaxial cables with generic, low-cost ones. He recorded substantial sonic differences between the expensive and the generic ones. Steve is a reputable analyst: was he dreaming and putting his good reputation at stake? In contrast, no test of Lighting cables has been conducted yet. Actually, I did test a few in my analysis of the ddHifi MFiS06…and found no obvious difference.

Self-acclaimed “objectivists” claim digital data don’t make a difference. This is based on measurements that do not reflect the quality of the data stream – and no physical connection between them and sound is established. And because the measurement setups are as arbitrary as the interpretation of the results, there is nothing objective about them. Nada. Zilch.

To add insult to injury, such protagonists typically don’t bother testing the gear with their ears they lecture the rest of us about. As we know already from earphones: graphs are insufficient for characterizing the sound of a device. And nothing is objective anyway.

Being opinionated is not being objective!

Whatever the theory tells us is one thing, listening is another. What’s important in the end is sound and not opinion. I have written all of the above before any listening test of the MFi09S cable.

Sonic Effects of Noise

I have experienced and described the effects of EMI and RFI (as well as switching noise, but not jitter) on the example of power supplies, for example the Burson Super Charger or the Allo Nirvana & Shanti and ifi Audio Power X. Contamination muddles the sound, it loses clarity and transparency. In the Burson case, I have no desire to go back to the stock power supply, the difference in the amp’s sonic performance was that huge.

Listening

We have learnt that the ddHifi MFi09S Lightning to USB-C cable is just one piece in the noise puzzle, sandwiched between a potentially noisy phone and a USB noise filter and a reclocker. That’s when the less imaginative audio linguist pulls out the phrase “your mileage will vary”. It is not a black and white affair. If the signal incoming from the phone is clean (just switch the Wifi and cell connection off), all a poor cable can do is deteriorate the signal, whereas a good cable has a high data integrity.

Round 1: iPhone SE (1st gen.) with different Lightning Cables

For my testing, I connected my iPhone SE (1st gen.) to the Questyle M15 DAC/amp with different lightning cables:

• ddHiFi MFi09S
• ddHiFi MFi06
• ifi Audio
• makeshift lightning cable 1: TC28i adapter with USB-C charging cable
• makeshift lightning cable 2: Apple camera adapter with USB cable

I then listened with the Moondrop Katos the Final E5000s. If there is a sonic difference between these cables, it is not obvious…and therefore negligible. In order to remove all doubt, I moved on to round 2.

Round 2: iPhone SE (1st gen.) vs. Hidizs AP80 Pro-X DAP

I listened with the Moondrop Kato’s to the following two setups:

• iPhone connected to the Questyle M15 via ddHiFi MFi09S cable
• Hidizs AP80 Pro-X DAP connected to the Questyle M15 via a generic UGREEN USB-C charging cable

Phone and DAP served as transports only – but both use different music softwares. The Hidizs setup sounds obviously better: richer, deeper, cleaner, with better dynamics and more headroom. I speculate the cleaner data stream and/or the different encoding from the dedicated (and therefore less noisy) player make the difference, but not the cable. The paradox is that a technically superior cable may not matter at all in many cases because of the other sound-influencing factors.

In the two test rounds, I toggled the phones cellular connection, Bluetooth, and Wifi on and off in all possible combinations, which also made no sonic difference.

Round 3: iPhone into Marantz SA8005 with different Lightning Cables

To put the lid on the pot, I played the iPhone through the Marantz SA8005 SACD player into the home stereo – and listened with the Sennheiser HD25 headphone with its integrated headphone amp. The MFi09S did not work at all, neither did the ifi Audio OTG cable – the iPhone was not recognized by the Marantz. Only the Apple Lightning cable, an MFI-certified Startech USB cable, and even a cheaper MFI-certified UGREEN charge cable worked. And no, there was no audible difference either.

Reasoning is the fact that the Marantz, like a Mac computer, requires a bi-directional power line (with charging functionality) to communicate with the phone. OTG cables generally do not offer that.

Interpretation

All cables tested “sound” the same. They appear to be reasonably well shielded against EMI/RFI and the metallic wire material used makes no sonic difference but rather other factors such as the source (software, noise) in the phone’s case.

In other words, the MFi09S is overkill for my applications. It may be as good as intended but cannot show its qualities in my setups. It would make a difference if the client DAC was emitting EMI/RFI, but this is a special case. The other fact to consider is that a DAP without network/general computing capabilities sounds better than a phone, even with a budget cable.

Although the MFi09S makes no sonic difference in my tests, it is still not snake oil!

Concluding Remarks

Whether a digital cable makes a sonic difference depends mainly on the data quality of the host. If my phone emits a noisy signal, even the best cable is wasted on it. On the other hand, even the cleanest signal can be contaminated by a poorly designed cable.

ddHiFi’s series of “audiphile” digital cables connects computers, daps, and phones to client DACs. Phones typically produce the noisiest data stream. The fact that I don’t hear a difference in sound quality between the MFi9S and other lightning cables may lie in the problematic phone source. An “audiophile cable” may simply be overkill for this job.

In summary, the lack of “obvious sonic improvement” as claimed by ddHiFi may not reflect on the cable – such a general claim is simply not tenable as such “improvement” (rather call it “lack of deterioration”) would depend on many other factors, too.

But just as with earphones cables, the MFi9S is a haptically substantial, well-handling, durable cable with quality connectors that also adds a visual “jewelry” effect to your OTG setup. Unless you are keen on the overpriced, white, easily fraying Apple equivalents…And there is still ddHiFi’s lower-priced MFi6 cable.

UPDATE 2023-01-03: I also tested the USB-C version of this cable, the ddHiFi TC09BC, and it does make a difference in my test setup. And there is a good explanation why…

Until next time…keep on listening!

Current-hungry DACs drain our DAP/Android Devices fast – and Apple’s current-draw limit frequently just results in an error message. The solution is an external power bank – which is easy in the DAP/Android case, but still problematic with iOS devices. Here’ s how to do it…with the E1DA splitter (2 kinds) and the Apple Camera Adapter.

This article is based on discussions with Alberto and I thank him for his insights…which have cost me lots of sweat in the meantime. Gordon Rankin or Wavelength Audio pointed the Apple restrictions out to me. I purchased all these cables myself. My testing refers to extreme cases. The E1DA splitters work as advertised as they are optimized for their own products.

Introduction

Dongles are little DAC/amps that draw their operating current from the host, which is either a computer, phone, DAP, or tablet. They have the advantage that they do not subscribe to planned obsolescence as they do not rely on an internal battery that dictates their life span. And they are small because of it. That’s why I like them.

There are principally two kinds of dongles, such that limit current draw to preserve the host’s battery, and such that…don’t (I wrote about this here). The first are limited in their performance, and the second drain the host (too) fast. Remember the 36 hours we got out of our iPod Classics?

Apple adds the “fun fact” of limiting current draw to 100 mA for most of their iOS devices. Reason is their fear of dissatisfied customers falsely claiming battery failure on warranty when their phones’s batteries drain “too fast”. If we connect our dongle with a current draw exceeding 100 mA, we get no music but a cryptic error message instead. Not good.

There are exceptions, when the iOS device is fooled to believe the draw is below 100 mA…by means of fudging the descriptor table in the software (according to Gordon Rankin of Wavelength Audio). Hidizs S9 Pro and ifi Go Bar (both around 140 mA), for example, appear to get around the restrictions, as both work with my iPhone SE (1st gen.), Astell & Kern’s PEE51 does not.

Luckily, some third-party Lightning cables exist that trick the iPhone to believe the current draw is lower than 100 mA…which is only a short-term solution, as it does not stop the battery from draining fast. E1DA have published a useful spreadsheet that tells you which Lightning cables work with which iPhones with their 9038SG3 and 9038D DACs (which draw above 130 mA).

Android devices and most DAPs are more forgiving – and work even with the biggest current w**res (excuse my Italian). But not for long in each case before you have to hook your device back up to the charger.

Therefore, in order not to run out of juice prematurely – and to entice Apple devices to play through our monster dongles – we need to use an external power source to drive those – and the readiness of the host to accept them.

The theory is simple: just separate power line and data line in the cable connecting host and dongle. As a result, the dongle draws its power from an external 5V power bank (or out of our 5V wall charger), and its data (“music”) from the phone/DAP/tablet. Computers are exempt in our discussion as they always provide enough power to any dongle (USB 2 up to 500 mA).

Stop! The theory may be easy for Android devices/DAPS, but things can be way more complicated for iOS devices, when the 100 mA current-draw limit needs to be circumvented.

What we need for DAPs/Android devices is a splitter cable (with separate data line and power line), an external battery, and the music host. This also works for iOS devices with <100 mA draw, but the Apple Camera Adapter is needed for anything higher. And that’s not all: you also need an MFI-certified USB-A (or USB-C) Lightning charging cable to make it work. Let’s test all possible cases.

DAPs/Android Devices with external Battery and E1DA Splitter

The easy case first to warm you up for things to come. What we need:

• Music source
• $4.99 E1DA USB-C to USB-C splitter cable
• Power bank
• Dongle (here the current hungry, 280 mA consuming, very powerful Apogee Groove…with micro USB to USB-C adapter
• Headphone

We plug it all in – and it works. The source device is not charged during music play and the Groove receives the required current from the power bank. Easy peasy!

iOS Devices with external Battery and E1DA Splitter vs. Apple Camera Adapter

1. Dongles with a Current Draw <100 mA (or a Software Manipulation pretending it is <100 mA) –> E1DA Splitter and Apple Camera Adapter work

Well, that’s smooth when the connected dongle draws less than 100 mA as it essentially works like the DAPs/Android device above. It just need a different E1DA USB-C to Lightning splitter cable that sets you back $19.99. Just in the case above, your iOS device is not being charged during operation.

2. Dongles with a Current Draw >100 mA (and without Software Manipulation pretending it is <100 mA) –> only Apple Camera Adapter works, E1DA Splitter does not

In this case, the E1DA USB-C to Lightning cable does not work. All you get is an error message. The power bank fuels the Groove properly, but there is no chip telling the iPhone it does actually not have to supply power to the Groove. Hence the iPhone reacts as it would without power bank: it does not want to do it. Thank you, Apple.

We still can drive the Groove but need different equipment to do so. Please fasten your seat belt! We need the following ingredients:

• iOS device
• $49 Apple Lightning to USB 3 Camera Adapter
• Power bank
• MFI-certifed Lightning charge cable
• Dongle (here again the current hungry, 280 mA consuming, very powerful Apogee Groove)
• Micro USB to USB-A cable
• Headphone

This works beautifully. The power bank funnels current into the Apple Camera Adapter with its controller chip that informs the iPhone that it does not have to supply current to the Groove. And the Groove draws its power from the power bank, which is controlled by the iPhone. On top of that, the iPhone charges while playing.

But there is still another hurdle: the charging cable has to be MFI certified to be able to communicate with the Apple Camera Adapter’s controller chip. Lightning cables by Amazon (Basics), Apple, IKEA, Startech and UGreen worked in my tests, OTG cables by ifi Audio, ddHiFi, and OE Audio did not (they are unidirectional “the wrong way” and not designed for charging). No power through the latter – and the well known error message appears on my iPhone. Bummer!

Concluding Remarks

Driving dongles with DAPS/Android devices and power bank using the E1DA USB-C to USB-C splitter cable works universally.

In contrast, iPhones (tested with SE 1st gen. and 13) do not like to draw zero current when they are not told to do so by a controller chip. As it appears, the Apple Camera Adapter draws some current from the iPhone but also from the power bank. E1DA’s USB-C to Lightning splitter works different from Apple’s Camera Adapter as it talks to the dongle and not to the iPhones’s power management. Therefore, iPhone does not charge while being connected to the E1DA splitter.

And I wished E1DA added a chip (as in Apple’s Camera Adapter) to make their Lightning splitter universally usable (Apple apparently makes this impossible for audio designers without an MFI license – and E1DA are probably not an accredited MFI contract manufacturer). E1DA’s USB-C to Lightning splitter is therefore of limited use for third-party dongles – but it works as intended with E1DA’s own DACs. This cable is not MFI certified.

As a rule of thumb, E1DA’s USB-C to Lightning splitter will only work with dongles that iPhone believes are drawing less than 100 mA current. And Apple’s Camera Adapter only works with MFI-certified charge cables. Nothing is perfect.

Until next time…keep on listening!

The ddHifi TC35i is a dongle sonically identical to Apple’s lightning audio adapter in a more compact shape with a better shielded and more premium metal enclosure.

Pros — World’s most compact 3.5 mm lightning adapter; good sounding; compact; great design; rugged.

Cons — Pricey.

Introduction

When ddHifi released the TC25i, which is 2.5 mm balanced version of their lightning adapter, they were tight lipped about its internals. But rumour had it they used the same chip as found in the Apple dongle (the one that used to come with your iPhone).

And whilst the rumour solidified, Apple themselves never released the specifications of their own adapter. The TC35i analysed for this article also features the Apple chipset, so that the specs published here may give us insight into the Apple’s adapter design.

ddHifi have been specializing in attractive and well-made accessories (and lately also iems such as the Janus) that blend design and functionality in a way that put the whole company up on our Wall of Excellence.

Specifications

Physical Things and Usability

The ddHifi TC35i is the world’s most compact and most rugged Apple Audio adapter. Yes, it features the same tech components as its Apple counterpart: a microscopic stereo digital-to-analog converter (DAC), a stereo headphone amplifier, a microphone preamplifier, and monophonic analog-to-digital converter (ADC) – and power converters to run the whole.

The big difference to the Apple adapter is that the TC35i comes in a metal enclosure that is not only much sturdier but it also provides better shielding against electromagnetic interference.

Amplification and Power Consumption

The key asset of Apple’s internal dac/amp combination was a very low output impedance of about 1 ohm, which should be indentical in the TC35i. We ideally want a low output impedance for any music player (<3 ohm) for optimal earphone/earphone pairing.

The Apple adapter not only has an output impedance of <1 ohm, it also has by far the lowest power consumption of all the dongles I have tested. Again, this should also be valid for the TC35i. In terms of amplification, Apple/TC35i handle iems and headphones up to 50 ohm impedance with ease. The 70 ohm Koss Porta Pros are marginal.

Sound

The TC35i’s sound is neutral, clear, clean, transparent with accurate and tight bass reproduction. In comparison, most dongles such as the Helm Bolt, Shanling UA2 or the AudioQuest DragonFlys are slightly coloured. The ddHifi dongle works well with even the most sensitive multi-driver items.

Anything the TC35i drives sounds excellent be it phone or computer. The Audioquest Dragonflys actually add bass and therefore colour (“warmth”) whereas the TC35i is more neutral. It is hard to find a dongle that equals or surpasses the TC35i/Apple audio adapter in terms of dynamics, clarity, cleanliness, and imaging.

Concluding Remarks

The ddHifi TC35i is the world’s smallest and most compact Apple audio adapter, improved over the original trough better shielding and a more rugged design. And a more premium look and feel. It may not be the most powerful but will drive any iem up to 50 ohm with ease at a sound quality adapted from and designed by the engineers of one of the world’s most influential tech companies. The TC35i delivers proven quality in a better shell.

Until next time…keep on listening!

The ddHiFi Carrying Case C2022 is a well-made textile-leather carrying case for personal audio gear. It is roomy enough to hold a couple of daps or portable headphone amplifiers plus accessories.

Pros — Spacious, practical, attractive, great workmanship approved by a seamstress.

Cons — Buckles made of plastic (not metal); no shoulder pad.

Introduction

ddHifi have left a big impression on us in the past. The company sparkles with innovation with their adapters, cables, earphones, dongles, and other accessories. Anything they released is not only extremely useful but also optically and haptically of the highest quality. Any premium earphone that went through Calgary on a Head-Fi tour contained at least one ddHifi adapter. It is therefore no wonder that the company made it as a whole onto our Wall of Excellence.

I love storage. Being German by trade, I like to have my gear orderly stowed, but also quickly accessible. ddHifi’s C-2020 case fulfills all these requirements, but it is a tech organizer and a pure storage device, bulky and therefore best suited for travelling in our luggage.

The C2022 is a totally different design – inside and outside – to be worn on the go while playing music – if desired. It therefore has a different functionality. Both cases are complementary.

Let’s see what the C2022 case can do for us…

Specifications

Physicalities

The C2022 carrying case is largely made of double-strand nylon on the outside, with cowhide leather at the bottom and on the sides. The inner lining is of polyester. It comes with a shoulder strap that is also made of sturdy nylon and adjustable in length. It is plenty long for a 6 ft/180 cm guy like me. The velcro straps are of very good quality and so is the zipper.

I showed the C2022 to my sister-in-law who is a seamstress. She approved of the stitching and the ruggedness of the fabric. Not much I can add.

Functionality

The ddHifi C2022 case looks very much like a camera bag. Since its compartmentalization is impossible to photograph, I drew its layout schematically.

• Green: On the outside is a “frontal zipper pouch for small items” (iems, SD cards, batteries, adapters). Too small for iems.
• The main bag is divided into 3 compartments: slim front and rear pockets with double velcro straps (blue) for phone, dap, power bank, dongles etc.
• The middle pocket (red) is extremely roomy and offer storage even for the fattest Discman, Walkman, even a small desktop amp…the sky’s your limit.

There are several loops on the back and the sides for attaching shoulder strap, carabiners or similar and/or strapping the case to another device.

Let’s now have a look what this looks like in real life.

These plastic parts may be sturdy and light but I preferred the metal in the C-2020.

When actually using the C2022 bag on a daily basis, I found it interfering with my arms because of its depth. It sticks out from the body quite a bit. I’d prefer a different aspect ratio: wider and less deep, like a map case (and not so much like a camera bag). I’d also appreciate a shoulder pad for increased comfort considering you can load this bag up quite a bit. But maybe this shape is optimal for you. You can see that readily from the photos.

As to the price, I don’t find $50 particularly cheap, but it is all relative. A Van Nuys bag costs you three times as much. After all ddHifi use real leather. Nevertheless do I find the identically C-2020 bag a better value (with more metal and more leather).

Concluding Remarks

Well, schlepp your audio gear around while listening to it with this well-made, rugged, and practical ddHifi C2022 bag. I am taking it on an intercontinental trip to Europe this July. It may not be the cheapest solution, but when looking at a comparable Van Nuys, Coach, or Louis Vuitton, you may be out a multiple of what you pay for the C2022.

Until next time…keep on listening!

Cons — None.

Executive Summary

The ddHiFi MFi06 and TC03 are digital cables that are well conducting, well insulated, built rugged and priced right. And they add optical appeal to our devices.

Introduction

ddHiFi have been favourites of our blog for quite some time. They produce very well designed, functional AND optically appealing audio accessories and even earphones.

I have tested their TC25i and TC28i adapters, their Carrying Case C-2020 as well as their Janus E2020A and Janus E2020B earphones. And I purchased a few of their audio adapters. For their accessories, the whole company is attached to our Wall of Excellence.

In this article, I am analyzing the MFi06 and TC03, two USB cables in the broadest sense. Both have a USB-C connector on one and, the MFi06 has a lightning plug on the other, and the TC03 a micro USB plug.

And all USB cables are equal, right? Zeros and ones transfer the sound, the stock cable is as good as the snake oil ones at $$$.

Erm, stop. Not always. The signal carried by the cable is not only zeros and ones (which are actually transmitted as voltage fluctuations), there may be some noise riding along the lines that affects sound quality. Two kinds of noise exist, “Electromagentic Interference” (EMI) and “Radio-Frequency Interference” (RFI).

If the data line is not effectively shielded, nearby electrical components (e.g., switching power supplies, other fluctuating electrical/magnetic fields from computer circuitry) can contribute to EMI that might pollute the USB data.”

Running power and data lines (from a phone or computer) through a single USB cable can cause additional interference and exacerbate the issue. Decrapifiers such as the AudioQuest JitterBug FMJ act as filters to reduce such pollution, but a “good” USB cable adds to this effect, too.

“Good” does not refer to the wire (that’s where the snake oil is) but to the insulation of the power and data lines against each other. In other words, a quality cable does not add anything, it makes sure that nothing is taken away from the signal quality.

A well-known example of the positive effects of insulation is the EarMen Sparrow dongle, that, when operated with a phone, can show strong interference in the shape of intermittent buzzing and clicking (subsides when switching the phone function off). The culprit is the stock cable, and a good third-party cable strongly reduces (but might not completely eliminate) the problem.

One measure of the shielding effectiveness of different cables, the resistance of shield terminations, was investigated in this thread.

Good-quality, well-shielded USB cables do not have to be expensive. USB audio pioneer Gordon Rankin reported very poor $$$ USB cables to me. It is all about the cable’s design, not the price.

ddHiFi are a company that offer a large range of imaginative, well designed, and well built accessories….and even a couple of earphones.

Physical Things

Both cables are 8 cm long. Wire material is high-purity silver-plated OCC copper.

Four strands of separately insulated wire serve as conductor. The inner insulation is teflon. The outer insulation is thermoplastic polyurethane imported from Germany. The aluminum alloy connector are cased in stainless steel to minimize external interference.

Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.

As it appears, these cables are technically sound. They feature good conductors and sufficient internal and external insulation. Sonically, they are indistinguishable from the OEOTG cable and one other brand of which I could not identify (see photo at the bottom of this article).

Haptically, the MFi06 and TC03 are vastly superior over the typical stock cables and the Apple Camera Adapter. The connectors feel rugged, the cable is flexible and the shiny, pearly white TPU is dirt and grease resistant.

And, let’s face it, these cables also add a jewelry effect to our gear. Yep, they don’t just feel good between the fingers, they also look good.

All good so far, only one worry remains: the MFi06’s battery consumption.

MFi06’s Battery Consumption

The MFi06’s lightning connector features a decoding chip which draws current from the phone. The question is how much it contributes to the phone’s battery drain.

I measured battery consumption of different dongles (AudioQuest DragonFly Red, Shanling UA2 single ended, Hidisz S9 Pro single ended) with the Apple Camera Adapter vs. the MFi06. I then repeated these tests with two other Lightning to USB-C cables (OEOTG and an unknown brand) for comparison purposes. All tests were performed under identical conditions. The absolute values are meaningless, what is important are the relative values.

.

Results:

1) The Apple Camera Adapter has by far the lowest power consumption.

2) In my 3 h tests, the 3rd-party MFi chip in the ddHiFi MFi06 cable consumed between 130 and 220 mAh (23%-36%) more (for my specific test parameters) than the one in the Apple Camera Adapter.

3) All three tested 3rd-party cables appear to have the same MFi chip (approx. same battery consumption with Shanling UA2).

4) Battery consumption of the ddHiFi MFi06 cable varies vastly between dongles. It is much lower for the DragonFly Red that consumes by far the least battery with the Apple Camera Adapter.

In summary, the MFi06’s power consumption is acceptable for today’s ever increasing phone battery capacities.

Concluding Remarks

The ddHiFi TC03 and MFi cables do what they are supposed to do: they work as promised while adding appeal to our devices. And they don’t break our piggy banks.

Until next time…keep on listening!

Executive Summary

The ddHiFi Carrying Case C-2020 is a well-made textile-leather carrying case for personal audio gear. It is roomy enough to hold a couple of daps or portable headphone amplifiers plus accessories.

Introduction

I started this blog over 2 years ago, focusing on earphone reviews. This didn’t change much even when we became more authors. But we eventually diversified into esoteric things such as earpads, eartips, earphone cables, even microphones and after-market strain reliefs. We found ways to separate the good from the bad in every possible genre.

When I first talked to Lily at ddHifi, we could not find an item to review. I simply did not see any application for their products. This changed rapidly when I needed an adapter for connecting 2.5 mm balanced cables to a single-ended 3.5 mm socket. I ended up ordering three different ones and was so happy with them that I finally reviewed these two adapters for ddHifi.

And I started liking their stuff. Very much so. Everything by ddHiFi I have touched has turned out to be superb in terms of both functionality and quality. The C-2020 case is no different.

I see the C-2020 carrying case as a challenge for me as a reviewer. Not so much for the written account – other than perhaps conveying the message as compact as the case itself is. No, I was really keen on doing a video on something as exciting as a case – and make the video actually really exciting. You can see the result here:

Specifications

• Dimensions: 24*17*8 cm
• Weight: 410 g (excluding strap)
• Outer Material: bifilar fabric and Italian cowhide leather
• Inner Lining: polyester and elastics
• Zippers: dual, 2-way
• Straps: 2 (hand and shoulder)
• Tested at: $57
• Product Page: ddHiFi
• Purchase Link: dd Official Store

Physicalities and Functionality

Workmanship is top notch: outer shell material is sturdy and appears to be water repellent, and it is nicely alternating with leather pieces that make the whole case smell good. Really good.

The double zippers appear to be rugged and sturdy. And the inner polyester lining is standard quality. The case can be worn over the shoulder or on the wrist. Wrist strap and shoulder strap are included.

There are two main compartments, a deeper upper one and a slimmer lower one. See images below. From now on I recommend watching the accompanying video as writing the obvious can become a boring read.

UPPER “DEEP” COMPARTMENT: for two bulkier items such as daps/headphone amplifiers and 2 iPod classic shaped devices/phones. The compartment can be subdivided by two dividers attached by velcro to fit any device. Rubber straps attached to the bottom offer additional hold.

LOWER “SHALLOW” COMPARTMENT: for SD cards, cables, dongles, adapters, earphones.

You see the case in action in the Gallery at the bottom of this article.

What My Wife Says

That’s the real test. Somebody hanging out at the Coach outlet store in Las Vegas should know. My wife says about the C-2020 case: attractive; good quality, great stitching, good leather, nice compartments, practical…if this was from Fossil, it would be way above $100. Well, she does not see a reason for the carrying strap.

ddHifi C-2020 Case Compared

Oh, these silly comparisons. Louis Vuitton does not offer an audio gear case. And if he, did, we could not afford it. But let’s face it, the amazon basics polyester-padded cardboard box I had before was a piece of junk.

Concluding Remarks

Whatever ddHiFi releases appears to be well thought out, beautifully designed, functional, and built well. The C-2020 carrying case fits this bill. I have been using it to store my portable amps since the day of arrival. For the price of yet another Chi-Fi earphone, I’d rather treat myself to a nice case.

Until next time…keep on listening!

Cons — No gain switch; rather big; non-serviceable battery.

EXECUTIVE SUMMARY

The EarMen TR-Amp is a powerful neutral but not sterile of generic sounding integrated headphone amp (dac/pre-amp) that drives headphones up to 300 Ω) with ease. Made in Europe.

INTRODUCTION

EarMen recently appeared big on our radar out of nowhere, with their two models the TR-Amp (“transportable amp”) and the Sparrow dongle. The company is a subdivision of premium manufacturer  Auris Audio. Earmen is registered in the US, where most of its stakeholders are from. The new Chicago warehouse has its focus on the North American market. The production is currently in Krusavec, Serbia [video of production facilities]. EarMen is “Made in Europe”.

I have used the EarMen TR-amp for 4-5 months, mainly with the 300 Ω Sennheiser HD 600 headphones. This worked so well and the TR-amp so so easy to operate that I had real problems writing an actual review other than telling you that it “works well and is really good”.

I apologize to EarMen that it took me so long to write this article.

Product page: https://earmen-shop.com/products/tr-amp

PHYSICAL THINGS

In the box are:

• TR-amp
• USB-C to USB-A cable, 1 m
• rubber ring (for strapping TR-amp to phone)
• storage meshbag
• manual/warranty card

The case is of sturdy aluminum, knob and switch are metal, there is nothing plastic. Rubber feet on the bottom prevent the metal chassis from being scratched/scratching the underlying surface such as a smartphone. The build is so sturdy that you can probably use it in self-defence – and it will still work thereafter.

The EarMen TR-amp features the TOTL ES9038Q2M SABRE dac chip and the Texas Instruments TPA6120 headphone amplifier chip. 

FUNCTIONALITY

The EarMen TR-amp connects to smartphones vial plug ‘n’ play, it needs a driver for Windows (download) and none for the Mac.

WHAT IT DOES

• Can be connected to phone or Windows/Mac computers or Android/iOS sources
• Works as a pre-amplifier or dac when connected to a dedicated headphone amplifier
• Plays two earphones/headphones simultaneously through its two outputs (3.5 mm/6.3 mm)
• Drives small loudspeakers through its RCA outputs
• Plays and charges simultaneously through its two USB-C ports (5V power supply/charger)
• …Or runs on its built-in 3700 mAh battery
• Handles even power-hungry headphones well, imo up to 300 Ω

WHAT IT DOES NOT

• There is no choice of different digital filters
• It has no gain switch
• The output impedance is fixed
• Cannot be used as an amp only as it has no analog inputs

The EarMen TR-amp is a rather large for use on the road – I’d store it in my pocket rather than strapping it onto my phone. I like using it in bed with my phone, where size does not matter…at least amp size does not.

OPERATION

Operation is straight forward. “The music plays” – as they say – in the front and back panels…

Front Panel

The front panel of the EarMen TR-Amp features 2 outputs: a 3.5 mm and a 6.3 mm, which points to its particular suitability for full-sized headphones. The “On-Off/Volume” is nicely protruding out and therefore convenient to handle. That little LED serves mainly as an audio format indicator, and less so than a battery indicator: EarMen TR-amp is on (“white”), connected/PCM (“green”), MQA (“magenta”), DSD (cyan), charging (“flashing blue”), and low battery (“flashing red”). It is well visible while inconspicuous.

Rear Panel

The back panel sports two USB-C ports, a Pre Out/Direct switch, and RCA outputs.

One of the UBS-C outputs is used for charging, the other for data transfer. Both can be deployed simultaneously. When the EarMen TR-amp is connected to a computer, it is running on battery by default. You have to connect the other USB-C port to a USB-charger or external battery pack for charging.

The EarMen TR-amp’s amplifier function can be bypassed when connecting it to a (more powerful desktop) amplifier through the 2 RCA outputs. The switch serves the purpose of specifying the volume control. in the “Direct” position, the EarMen TR-amp’s volume knob is being disabled and the full-strength signal is being transferred through the”Line Out” into the external amp, which requires its own volume control. In the “Pre Out” position, the TR-amp’s volume control is activated.

Independent of the switch position both headphone outputs are always operative and two people can listen simultaneously.

AMPLIFICATION

The EarMen TR-amp works well with the Sennheiser HD 300 Ω impedance headphone (and therefore most on the market), but its 350 mW into 32 Ω would probably not drive more exotic 600 Ω headphones well. Power details in the specs above.

POWER CONSUMPTION/PLAY TIME

Ear Men claims up to 10 hrs of play time but does not give you specifics on the setup. I tested with the power-hungry Sennheiser HD 600 and iPhone 5S at a “normal” but pretty healthy volume level. After 6 h and 15 minutes, the indicator light started blinking, which means the the battery level and dropped below 20%. This points to 7-8 h playtime with this setting.

I value this as being in line with the manufacturer’s claims.

SOUND

My tonal preference and testing practice

My test tracks explained

Equipment used: EarMen TR-amp; Macbook Air, iPhone SE 1st gen.; Apple camera adapter, ddHifi TC28i adapter; Schiit Magni 2U headphone amplifier with Audioquest Forest and Snake Oil Taipan RCA interconnects; 300 Ω Sennheiser HD 600 headphone, 16 Ω Sennheiser IE 300 earphone.

The “ingredients” of the EarMen TR-amp are top notch, but how good is the “cooked meal”? Such a device works well with your phone on the go (if you like strapping it around it), but it can also be deployed as a desktop amp, and it can also be used as pre-amp or dac, when connected to a “bigger” dedicated headphone amplifier.

I tested the TR-amp in these scenarios:

1. …as dac-amp with MacBook plus headphones/earphones
2. …as dac-amp with phone
3. …as dac AND pre-amp with Schiit Magni 2 Uber, sourced by MacBook

The EarMen TR-amp, just like the Sparrow, produces a neutral sound with a tinge of warmth added to spare us from a clinical, lifeless, or overwhelming sonic reproduction. Straddling that thin line, it allows for harmonizing with both, neutral and warm headphones/earphones.

Extension towards both ends is very good and so are headroom, sense of space, and dynamics. The punch is natural and works with electronic, rock, and acoustic music such as symphony or jazz. The image has a good volume and body, it does neither sound lean or syrupy thick. The TR-amp preserves the music’s midrange clarity and brings vocals out intimately.

I also could never hear any noticeable hiss, not even with the sensitive 16 Ω Sennheiser IE 300. But it brought out the bassy side of these naturally bassy iems without muddying or congesting the sound.

It is really boring to report the sound of an amp that does not alter music and reproduces it as should be. The EarMen TR-amp simply works and has been for quite some time for me.

Using the EarMen TR-amp with as a pre-amp (“Pre-Out”) and dac (“Direct”) with the warmer Schiit amp adds a bit of colour and results in added power and heft. This is only valid for this particular setup . Sonic results will vary with different amps connected.

What I’d like to see is a gain switch for easier volume fine adjustments with sensitive earphones.

EARMEN TR-AMP COMPARED

I can only offer the $199 British nano iDSD Black Label (“BL”), which is a bit smaller and less powerful (285 mW vs. 350 mW @ 32Ω) – both feature a 3700 mAh battery. The BL does not drive the Sennheiser HD 600 as well as the TR-amp, but it has two 3.5 mm outputs, one of which (“IE Match“) offers increased output impedance for sensitive iems. The more powerful TR-amp is rather designed towards full-sized cans with its 6.3 mm output – whereas the BL caters more to the less power hungry peripherals…although both play both well.

The BL is warmer sounding and therefore more limited to the more neutral headphones/earphones, it may sound muffled with warm earphones/headphones. The EarMen TR-amp is more versatile in this respect. The BL has the choice of two audio filters, the TR-Amp does not. And the BL has a pseudo 3.5 mm balanced circuit.

In terms of connectivity, the EarMen TR-amp has a L and R line out, the BL has a single 3.5 mm line out. Both can be used as dacs, and only the EarMen as pre-amp. The TR-amp, with its separate UBC-C ports for charging and data can be charged while playing, the BL with its USB-A port can draw power from the source (“computer”) or run on battery, but it cannot play and charge simultaneously.

CONCLUDING REMARKS

The Earmen TR-amp has been playing everything I threw at it in the last few months, from sensitive iems to the 300 Ω Sennheiser HD 600. And it played them all very well. It is a robust classic design that feels and sounds good, that is powerful enough for almost anything, and that is reasonably priced. It simply works for me and don’t want to miss it.

What else can I say?

INTRODUCTION

I love adapters. Yes, you are reading correctly. I have boxes of them…see photo at the bottom. But when I recently received a couple of German premium earphone review loaners with a combined worth exceeding $5000, they came with an adapter. And guess wh

at, it was a ddHifi branded one. A Chinese adapter on a German premium earphone cable? Must be of good quality. And it was. In fact it worked so well that I purchased three versions of it way before I received the actual two units for this review.

One of them, the ddHifi TC25i let’s one connect a 2.5 mm mm balanced cable to an iPhone’s lightning port. The other one, ddHifi TCI28i, turns the iPhone’s lightning adapter into a USB-C port. I will explain the practicality of these devices in the following – also get some idea from the images throughout and at the bottom of this article.

SPECIFICATIONS TC25i

• Material: Aluminum alloy
• Dimensions: 0.7 x 0.4 x 0.5 in (18.5 x 9.5 x 13.5 mm)
• Tested at: $30
• Product page: ddHifi

PHYSICAL THINGS AND USABILITY/FEATURES

The TC25i and TC28i are robust, sturdy, small, and light – and made of metal. Build and haptic are excellent.

What do these adapter do? I’ll discuss this as follows. Note: the reviewed versions will only work with iPhones and iPads, even if these devices are mantled with the thickest possible cases. And – in order to give you some idea what these adapters can be used for, I appended a set of images of my own applications below.

TC25i Lightning to 2.5mm Headphone Adapter: is essentially the equivalent to the Apple lightning audio adapter (which I reviewed in great detail), but with a 2.5 mm output. Although all 2.5 mm cables are “balanced”, the TCi25 is not. Its sister adapter TC35i features a 3.5 mm adapter and serves the same purpose as the Apple lightning adapter.

The TCi25i/TC35i have a lot of technology packed into that small enclosure: a microscopic stereo digital-to-analog converter (DAC), a stereo headphone amplifier, a microphone preamplifier, and monophonic analog-to-digital converter (ADC) – and power converters to run this all.

Considering that any connector is a sonic bottleneck and that the wire in the Apple Audio adapter is the limiting factor for any premium cable, cable aficionados are better off with the TCi25.

TC28i Lightning to USB Type C Adapter: is simply a connector for dongles. It essentially serves the purpose of the Apple lightning camera adapter. When connecting your iPhone to a dongle via the Apple adapter, you create a rather long chain. The TC28i shortens this “snake” and makes it more portable.

There is a big difference, however, between Apple and ddHifi in that the former has the traditional USB-A connector whereas the ddHifi TC28i features the smaller USB-C connector.

This is no problem as most dongles come with either connectivity. And if everything fails, there are cheap USB-C to USB-A connectors.

TONALITY AND TECHNICALITIES OF THE TCI25i

First test of the ddHifi TC25i lightning to 2.5 mm adapter against the iPhone 5S’s internal dac/amp (which is essentially identical to the Apple audio adapter for later iPhones).

The iPhone 5S is a formidable audio player: https://www.kenrockwell.com/…/iphone-5s-audio-quality.htm. Result: no noticeable difference found in terms of sound quality and amplification power.

So what does the TC25i sound like? I agree with the Headphone Collector also analyzed the Apple audio adapter [here]…as said, the ddHifi TC25i sounds essentially identical . He writes: “…Neutral, clear, clean and very precise. Basically as audibly transparent, good-sounding and clean-sounding to my ears as it gets. Precise and tight bass reproduction with sensitive multi-BA in-ears.

VALUE

TC25i Lightning to 2.5mm Headphone Adapter, although identical sounding as the Apple Lightning Adapter, may appear expensive at four times the price.

But: Apple does not offer a 2.5 mm adapter and their dongle is plastic/rubber with a cable that is prone to fray. The TC25i is made of metal (and has therefore the much better haptic and durability), is much less conspicuous because of its smaller size, and is extremely practical as you don’t have to earphone change cables when switching between devices.

It is also classy compared to the Apple. And it is particularly useful when deploying cables with the unreliable MMCX connectors. It may save you money in the long run by not ripping your MMCX connectors apart.

The TC28i Lightning to Type C Adapter costs about the same as the Apple camera adapter. Again, the ddHifi product is smaller, more rugged, and has the better haptic. The difference between the two – that is USB-A for the Apples and USB-C for the ddHifi – is somewhat unimportant as most peripherals come with both-type cables – and if not, there are cheap quality adapters, the best from UGREEN.

CONCLUDING REMARKS

I love adapters and the ddHifi adapters are on top of my list. They are high-quality and therefore good enough to be used with the most premium equipment, they look and feel good, they are priced right, and they are extremely practical.

While these two units had been provided by dHifi, I purchased other ddHifi adapters for my pleasure so impressed was I. You will see ddHifi adapters all over this blog. Check it out for yourself:

EXECUTIVE SUMMARY

The Tempotec Sonata BHD is a neutral, sleek, crisp, and transparent sounding 2.5 mm balanced dac/amp that offers a substantial sonic update over phone/computer dacs/amps when used with iems. One of my favourite products in 2021. A personal favourite.

NOTE

I did not test the Sonata BHD with headphones owing to the lack of a balanced cable. Considering its power, the Sonata BHD is much better suited for iems. I also did not test DSD and MQA, as I do not have the required subscriptions. And I think the Sonata BHD is more tailored towards mobile units than towards computers.

INTRODUCTION

Chinese manufacturer Tempotec made quite a dent with their Sonata HD Pro in 2019. At $40, it comes with all possible adapters and you can connect it to essentially everything: Android devices, Apple devices, and computers. Not bad at the price of essentially an Apple lightning adapter. Unsurprisingly, the Sonata HD Pro has been a favourite in terms of audioreviews.org blog views since, made it into my “Gear of the Year 2020“, and remains highly recommended.

The Tempotec Sonata HD Pro features a single-ended output, whereas, in the meantime, companies like Earmen offer two outputs in their Sparrow dongle: 3.5 mm single-ended, and 2.5 mm balanced. And while I thought “balanced” was just another gimmick, it is truly not: everything sounds bigger and clearer with balanced in a direct comparison. But the Earmen Sparrow comes at a price of $200. Tempotec responded to the market’s demand for “balanced” output with their Sonata BHD, a sleek and powerful dongle at $70.

To answer you burning questions right away: does the Sonata BHD sound better than the Sonata HD Pro? Yes, it does. Does it sound as good as the Earmen Sparrow? No, not quite, but it still sounds impressive.

THE IDEA OF BALANCED AUDIO

Balanced audio is a method of connecting audio equipment using balanced lines [Wikipedia]. Such lines reduce susceptibility to external noise caused by electromagnetic interference. This is particularly beneficial for recording studios, which use kilometres of lines. For our purpose of portable audio, reduced interference results in a clearer, cleaner signal. Headphonesty compared “balanced and unbalanced” audio connections in this article.

PHYSICAL THINGS AND USABILITY

The Sonata BHD comes with a fixed USB-C cable, a USB-C female to USB-A adapter, and a pleather case. It does not feature the detachable cables of the Tempotec Sonata HD and is aiming to be connected to USB-C and USB-A devices such as Android phones, and Windows and Mac computers. It can be connected to iPhones/iPads using either the Apple camera adapter or the much sleeker ddHifi TC28i adapter. Therefore, adding a third-party adapter makes the Sonata BHD as versatile as the Sonata HD Pro with source devices.

In terms of dimensions, the Sonata BHD is slimmer and higher than most dongles. And like the Sonata HD Pro, the housing is made of metal with rather sharp corners. Tempotec increased the often criticized spacing between the two volume buttons compared to the Sonata HD Pro – what they have not addressed is the volume steps when pushing the buttons (which are identical to the source’s volume buttons). The button mechanism is exquisite and precise – with a great soft rebound – so that is is almost fun pushing them. All connections and connectors work precisely, too.

Internally, the Sonata BHD features the same chip as the Sonata HD Pro, however TWO of them (one for each line), which explains the price difference.

FUNCTIONALITY

The Tempotec Sonata BHD has no internal battery and is driven by the music source. This is great in that there is no planned obsolescence (the device will still work in, let’s say, 10 years), but it drains your mobile source faster. As to the drain rate, I did not explicitly test it – but battery consumption appeared to be within reason.

The Sonata BHD is plug ‘n’ play with phones and tablets, and it requires selecting the device in my Mac’s sound panel (probably similar in Windows).

When playing, the Sonata BHD relies on the source volume. I typically set the computer/phone volume at 80%, although I am not sure whether I can turn it up to 100% without (more) distortion. After removing the Sonata BHD from my phone, it recognizes the volume setting upon reconnecting.

AMPLIFICATION

There is a paradox: a balanced output is typically more powerful than a single-ended output – and iems, on average, require less power than headphones: however balanced cables for headphones are harder to get and more expensive than for earphones. As a rule of thumb, external amplification is needed for headphones/iems with an impedance above 50 Ω. While most headphones exceed this number, most iems run at 32 Ω or lower. Iems above 50 Ω typically feature electrostatic or piezoelectric drivers. I don’t have any balanced-headphone cables but could test the Sonata BHD with power-hungry iems such as the Vision Ears Elysium, Triaudio I3, and NiceHCK NX7 Mk3. And they were all driven very well by the Sonata BHD.

I could not test the Sonata BHD with headphones – I don’t have one with a 2.5 mm cable – but was told it is not that powerful. I would therefore be careful with any headphone above an impedance of 70 Ω.

As to specs, the Sonata BHD delivers 120 mW into 32 Ω (and 20 mW into 600 Ω). This is twice as much as the original Sonata HD Pro offers.

TONALITY AND TECHNICALITIES

My tonal preference and testing practice

My test tracks explained

Equipment used: iPhone SE (1st generation) and MacBook Air; various earphones, mainly the Shozy Form 1.4.

The Tempotec Sonata BHD is a strictly neutral and sleek but never sterile or over-analytical sounding dac/amp that enhances the sound characteristics of the attached earphone/headphone. It is not only useful for running power-hungry earphone/headphones, it also improves the sound of easy-to-drive iems. Let’s take, for example, the excellent sounding, well reviewed Apple Audio Adapter that works well with my 16 Ω Shozy Form 1.4 iems. The Tempotec Sonata BHD simply adds midrange clarity and definition, opens up the soundstage, and increases headroom. And it adds pizaz to the sound…yep, it is rather punchy. These improvements over my phone are quite pronounced – and much bigger than with the Tempotec Sonata HD Pro.

Replacing the Tempotec HD Pro with the Tempotec Sonata BHD is like adding sour cream to your gravy: smoother, better balance, much bigger stage, better three-dimensionality, the sound is simply more appealing. Connecting my >50 Ω earphones added body, cleanliness, and smoothness on top of power.

WHO NEEDS THE SONATA BHD?

IMO, the Sonata BHD serves two specific purposes:

• Play power hungry iems (such with an impedance of > 50 ohm)
• Improve the sound quality of any iem, even at low volumes

First, there should be no problem playing a, let’s say, 70 Ω headphone such as the Sennheiser HD 25 with the Sonata, however it may be cost prohibitive to get a 2.5 mm balanced cable for headphones. Second, the Sonata BHD is not an ornament as so many other dongles. Any earphone sounds better on my iphone with the Sonata BHD compared to the Apple Audio Adapter or the ddHifi TC25i adapter (which is technically and sonically essentially identical with the Apple Audio Adapter). In comparison, the Sonata BHD adds clarity and definition, slims down the sound, and opens up the stage including headroom.

But I doubt that you will be able to drive full-sized 300 Ω cans with the Sonata BHD well.

TEMPOTEC SONATA BHD COMPARED

As said before, the Tempotec Sonata BHD upgrades the sound of the Apple Audio Adapter as well as their own Tempotec Sonata HD single-ended dongle. It does, however, not live up to the balanced circuit of the $200 EarMen Sparrow that excels in its more analog, fuller sound with an even better headroom. Nevertheless do I like both for their merits and one cannot replace the other. Similar to the different models in my earphone collection, both dongles hits different moods of the listener and I really enjoy them both very much.

CONCLUDING REMARKS

The Sonata BHD provides a huge sonic upgrade to your phone and is another winner from Tempotec. Is sounds better and is more powerful than their famous Sonata HD Pro, but is a bit more limited by its ootb connectivity. Adding a second dac chip has increased the price, which benefits the sound greatly. The Sonata BHD is not only good for amplification but also for improved the sound quality of easy-to-drive earphones and headphones. It is not an ornament as so many others. Once again, a superb device and great bang for your buck. As simple as that…I said it before.

Until next time…keep on listening!

EXECUTIVE SUMMARY

The EarMen Sparrow is a $200 battery-less warm-neutral sounding dac/amp with dual output: single ended 3.5mm and the more powerful 2.5 mm balanced. It is class leading in terms of both power and sound quality. The EarMen Sparrow supports playback from iPhones, Android smartphones, MacOS and Windows computers. It also plays all 32bit/384kHz formats: PCM, DoP, DSD64, DSD128 and MQA. It is the best dongle I have come across (in the $200 category) and was on my personal favourite gear list of 2020.

INTRODUCTION

Do all dongles sound equal? Are most dongles just ornaments? Should we rather go for a desktop dac/amp instead to get more value for money? All of the above have been mentioned in discussions lately. For years I have had a single dongle dac/amp, the Audioquest Dragonfly Black. I mainly used it with my iPhone and life was good. Until…

To make this clear a priori: the EarMen Sparrow is the best-sounding dongle I have tested too far…but also the most expensive one. And it is not an ornament.

EarMen is a company registered in in the US, where most of its stakeholders are located – and from where they focus on the North American market. EarMen are a subdivision of premium audio gear producer Auris Audio. The production is in Krusavec, Serbia [video of production facilities]: Made in Europe.

Dimensions: 42*22*8 mm

PHYSICAL THINGS AND USABILITY

In the box is the EarMen Sparrow, the warranty card, and two cables: USB-C to USB-C, and USB-C to USB-A. This allows the Sparrow to connect to Android phones/tablets, and any Windows/Mac computer. It features the ESS Sabre ES9281PRO dac chip – which is well implemented.

The EarMen Sparrow also works with iOS devices but requires the Apple Camera Adapter, which adds to a “monster snake”. The $30 ddHifi TC28i adapter offers the same funcionality but cuts the snake’s length enormously.

The actual EarMen Sparrow is a sturdy and filigree CnC machined aluminium construction with top and bottom covered by glass…although I wished it had come with a sheath to protect it from being scratched.

In contrast to most other dongles does the EarMen Sparrow offers two different circuits and sockets: a single-ended output through a standard 3.5 mm socket and a balanced output through a 2.5 mm socket. Both outputs/sockets work simultaneously. And it is the balanced output that makes the EarMen Sparrow particularly attractive.

THE IDEA OF BALANCED AUDIO 

Balanced audio is a method of connecting audio equipment using balanced lines [Wikipedia]. Such lines reduce susceptibility to external noise caused by electromagnetic interference. This is particularly beneficial for recording studios, which use kilometres of lines. For our purpose of portable audio, reduced interference results in a clearer, cleaner signal. Headphonesty compared “balanced and unbalanced” audio connections in this article. And yes, it works.

FUNCTIONALITY

The EarMen Sparrow contains no battery and is powered by the source device. It works plug ‘n’ play with computers, tablets, and phones (Windows/Mac/Android/iOS). And it requires adjusting the respective sound panel settings in Mac and Windows computers. Volume is controlled from the source device – there are no buttons on the EarMen Sparrow. It is as easy as that. The EarMen Sparrow decodes all 32bit/384kHz formats: PCM, DoP, DSD64, DSD128 and MQA. 

AMPLIFICATION

The EarMen Sparrow is one of the most powerful dongle dac/amps on the market according to AudioScienceReviews.com. Its 2.5 mm balanced output delivers 2.0 Vrms into 32 Ω and 4.0 Vrms into 600 Ω. This results in a power of 125 mW and 20 mW, respectively. The 3.5 mm single-ended output is 1.4 Vrms into 32 Ω and 2.0 Vrms into 600 Ω, which translates to 61 mW and 7 mW, respectively.

I don’t have a balanced cable for my 300 Ω Sennheiser HD 600 Pro, however the single-ended output drives them “ok”. The balanced circuit delivers enough power to drive the 70 Ω Sennheiser HD 25 on my Mac, which indicates that this is good enough for any iem. In fact, imo the EarMen Sparrow drives even the most power-hungry earphones very well with my Mac.

A bit of an enigma is the dependency of the EarMen Sparrow on my sources: it provides way more power when sourced by my Mac, but appears to be throttled by my iPhones 5s and SE (1st generation). I speculate this is caused by the Sparrow’s power consumption. Sound quality is not compromised and power-hungry earphones such as the TRI I3 are still driven sufficiently well. Newer phones and Android devices may not throttle the EarMen Sparrow’s power. The Sparrow, like most powerful dongles, appears to be a bit of a battery drain on phones.

UPDATE June 2021: Power Consumption Test: Parameters and Raw Results

I tested the power consumption of several portable headphone amps connected to my iPhone 5S. The conditions were as identical as possible: 3 h test, volume calibrated to 85 dB  ± 0.5 dB white noise with Dayton microphone, no sim card, BT off, no other apps open; network on, 32 ohm Blon BL-03 iem, Genesis’s Supper’s Ready (from the Seconds Out album) played in an endless loop.

The iPhone’s battery was fully charged at the start of the test and the remaining charge was measured thereafter. The result is shown in the table below. Since the tests were performed at different times and considering the ongoing battery deterioration, the results have to be seen with a grain of salt.

TONALITY AND TECHNICALITIES

My tonal preference and testing practice

My test tracks explained

The EarMen Sparrow is a neutral-warm sounding dac/amp (more neutral than warm), and therefore offers the best of both worlds. Whereas a warm dac/amp (such as ifi Audio products) harmonizes best with neutral earphones/headphones (e.g. JVC HA-FDX1, neutral amps (e.g. Earstudio HUD 100) pair best with warm iems (e.g. Sennheiser IE PRO series). Neutral amp with neutral iem may sound like metal on metal – and warm with warm may come across as thick and syrupy lacking clarity and transparency. The EarMen Sparrow appears to strike the right temperature balance to harmonize with most kinds of earphones. The other trait is its good extension in both directions and its full body and natural dynamics. The Sparrow has this quasi-analog sound.

And while the sound through the single-ended output is good, it is fantastic through the balanced output. The difference in sound quality is mindboggling (I A/B-ed a balanced cable between both sockets – with a 2.5 mm female to 3.5 mm male adapter for single ended). Apart from the power gain in the balanced circuit, headroom and clarity opens up substantially…the midrange comes out nicely…this worked even for the ~$3000 Vision Ears Elysium. After several months of using the EarMen Sparrow on my Mac, I conclude that the balanced output is as good as a desktop amp for iems – on a computer.

EARMEN SPARROW COMPARED

The neutral sounding $70 Tempotec Sonata BHD dac/amp with its balanced output is an impressive sounding device. The EarMen Sparrow, however, offers a richer, more analog sound, a larger headroom, and more power. It is also more versatile with its additional 3.5 mm single-ended output. The less powerful Sonata BHD has a leaner, sleeker but less creamy/soft/weighty sound with more clarity.

VALUE – IS THE EARMEN SPARROW FOR YOU?

Is the EarMen Sparrow worth its $200? Any answer has to be subjective. For people who regularly deal with >$300 earphones without blinking: yes, no questions asked. Simply makes them sound better.

For the rest of us: yes, but for any or all of these three specific purposes – from my perspective: for the balanced output that sets the EarMen Sparrow sonically and power wise apart from its competition. Second, it is best used with iems or less power-demanding headphones. And third, for use mainly with a computer, where the Sparrow flexes its muscles best.

CONCLUDING REMARKS

I have used the EarMen Sparrow for a few months now. It took me so long to publish my review because I didn’t know what to write – it just worked great for me, and I used it a lot for earphone testing. The Sparrow is the best sounding dongle I have listened to so far (up to $200), albeit also the most expensive.

What sets it apart from the competition are sound quality and power of its balanced circuit. I don’t think one needs anything “bigger” to drive earphones – it was good enough for the $3000 Vision Ears Elysium. And since it does not have a battery, there is no planned obsolescence – the Sparrow will last for a long long time.

It is the balanced output that makes the Sparrow fly high: first it opens up the headroom and then it makes it a most powerful dongle – ahead of the competition. The EarMen Sparrow is just a very fine dac/amp. One of my favourite devices of 2020…and likely 2021, also. Basta!

Until next time…keep on listening!
