Introduction

Once again, I am flattered to be able to review an EarMen product. This time, it's the recent premium battery-powered balanced headphone/preamplifier DAC/AMP called the Colibri. Actually, it''s a doped-up EarMen Sparrow: its aesthetics are very similar, but it includes elements that enhance its body and performance. It has a battery that gives it a battery life of up to 5 hours. It incorporates on/off, volume (+/-) and bass boost buttons. The balanced output is now 4.4mm and there is an extra USB Type C port for charging the battery. For all these reasons, the size has been increased, but the dimensions are still contained, only slightly larger than a traditional dongle. EarMen has opted to continue using the ES9281 PRO chip as the DAC, which allows it to support playback of files up to 32bit/384kHz PCM, DoP, DSD64, DSD128 and MQA. The Colibri is still quite a powerful device, capable of providing up to 3V on the balanced output and 1.5V on the SE output. In the following review we'll look at these and other goodies from this new little portable audio device.

Packaging

The EarMen Colibri comes in an eminently black box, with dimensions 194x145x46mm. On the main side, a real image of the device can be seen on the right-hand side. On the left side, in white lettering, you can see the brand logo, the name, the model and a description of the device. On the back, the Colibri is shown on all sides, as well as its specifications. With the cardboard cover removed, the box is completely black, with an even darker inscription of the logo and brand name. After lifting the lid you can see the instruction manual, a warranty card and underneath, the Colibri inside a dense, grey foam mould and a couple of other accessories, which are in a recess, on the right. The complete contents are:

  • The EarMen Colibri.
  • A black synthetic leather case with clip.
  • One USB Type C - Type C cable, textile covered, 1m.
  • An instruction and specification manual card.
  • One warranty card.

There is no short USB Type C - Type C cable and no USB Type A connection. The textile covering of the cable is nice, but it feels a bit stiff.
The leatherette case is quite nice, but the clip gives me a mixed feeling: I know it can be very useful for hanging in a pocket, but I don't know how practical it is attached to a phone or DAP. On the other hand, placed on my desk, connected to my PC, such a clip is not the most suitable thing to leave on the table. There are no markings on the case either, so we have to know all the connections and buttons beforehand. On the main side, there is a circular cut-out that reveals the LED with the operating logo.
The packaging is rather large for the size of the device.

Construction and Design

The Colibri measures 77x35x14mm and weighs 51g. It is slightly larger than a normal dongle, but it has a battery, so the size is contained. It still looks very similar to the Sparrow: it is a complete aluminium block, machined on a CNC machine. It has two glazed sides. On the upper face, at the top, is the brand name, in silver. Two thirds of the way up is the logo (in white), which in turn is the operating LED. At the bottom is the model, also in silver. On the rear face there are many silver inscriptions: at the top is the list of compatible files, in the centre the Hi-Res logo, at the bottom the brand name. Along the perimeter, there are the descriptions of the buttons and USB inputs. There are 4 round buttons, two on each side. On the left are the volume buttons. On the right, at the top is the on/off button and at the bottom, the bass boost button. On the same side, at the bottom, is the serial number, in small white letters. On the bottom edge, on the left is the USB Type C female data connection and on the right, the charging connection. On the top edge are the audio outputs, 4.4mm on the left and 3.5mm on the right. The balanced connector is gold-plated, while the SE is not.
The design is beautiful, sleek, attractive, and continuist. The glazed surfaces attract fingerprints very much. The weight is restrained and I don't understand why the SE output is not gold-plated.

Connectivity

As usual with Earmen, the Colibri is compatible with Android (via USB OTG cable), DAPS and PC with Windows 10. It does not support older versions of Windows. It does not have ASIO drivers. It will also connect to an Apple IOS smartphone, but it will require a suitable cable which is not included (Lighthing to USB). Apple MacOS is also supported.

Earmen Colibri 09_r.jpgEarmen Colibri 10_r.jpg

Operativity

To switch on the device, press the power button for 3 seconds. After switching on, the front LED will flash after 3 seconds to indicate the battery status:

  • 1 flashing: the battery has a charge <25%.
  • 2 flashes: the battery has a charge between 25% and 50%.
  • 3 flashes: the battery has a charge between 50% and 75%.
  • 4 flashes: the battery has a charge between 75% and 100%.

The front LED has the following indications:

  • White: Connected.
  • Green: PCM, DSD, DXD.
  • Magenta: MQA Rendering.
  • Red: not connected.

When the bass boost button is pressed, the front LED glows brighter.
The volume buttons allow you to control the volume of the connected source, be it a smartphone, DAP or PC. A short press of the on/off button pauses playback. Another press resumes playback.
With the current firmware, the operation is quite stable, although I have sometimes encountered a little hesitation in its operation, especially when starting playback. At this point there is a fade in. But the complete use is not completely smooth. In any case, these small details are insignificant.

Earmen Colibri 11_r.jpgEarmen Colibri 12_r.jpg

Measures

I had seen a discrepancy between the output voltage specified on the website and the one specified on the box. After measuring, the website is right: the maximum voltage for the 3.5mm SE output is 1.5V and the maximum voltage for the 4.4mm Balanced output is 3V. Well, it's actually slightly lower in both cases, but I don't think my measurement system is ultra-accurate in this respect either.
What does seem clear is that the output impedance is ultra-low. The maximum voltage measured for 33Ω and 100Ω loads, both SE and BAL outputs, yield the same voltage value as no load, implying that the impedance tends to zero. This is undoubtedly a great data that determines that the Colibri is very suitable for use with very sensitive, low-impedance IEMS.
The current delivery limit, on the other hand, remains at that magical 90mA in normal ambient conditions. This indicates that the specified power is higher than the actual power in the measured cases. On the other hand, the device is still very powerful, I just think that the specifications are based on the theoretical voltages and not on the actual current delivery, as is often the case.

No load SE

The voltage at 1kHz is 1.43V.

Earmen-Colibri-SE-No-Load.jpg


15Ω SE

The voltage at 1kHz is 1.35V, which gives a power of 120mW and the magical current value of 90mA. The power value falls short of the theoretical 150mW at 16Ω, a figure which, on the other hand, cannot be achieved with a maximum of 1.5V output, but with 1.55V and almost 97mA of current.

Earmen-Colibri-SE-015.jpg


33Ω SE

The voltage at 1kHz is 1.44V and a power of 63mW is obtained. Again, the power figure is below the specified 75mW, which again requires a voltage of 1.55V.

Earmen-Colibri-SE-033.jpg


100Ω SE

The voltage at 1kHz is 1.44V, achieving a power of 21mW.

Earmen-Colibri-SE-100.jpg


No load BAL

The voltage at 1kHz is 2.89V.

Earmen-Colibri-BAL-No-Load.jpg


15Ω BAL

The voltage at 1kHz is 1.30V, which gives a power of 110mW. Actually, the power is far short of the specified 560mW. At what point can the Colibri deliver 190mA at 3V, for a load of 16?

Earmen-Colibri-BAL-015.jpg


33Ω BAL

The voltage at 1kHz is 2.89V and a power of 250mW is obtained. On this occasion, the current is 88mA. That's close to the 280mW specified. But a quarter of a watt is a great figure.

Earmen-Colibri-BAL-033.jpg


100Ω BAL

The voltage at 1kHz is 2.89V, achieving a power of 83mW.

Earmen-Colibri-BAL-100.jpg


Frequency Response

Note: Bass boost deactivated.
Completely flat in the audible range, with very slight dips at the extremes. Note that both outputs overlap across the entire volume range, implying that there is no crosstalk.

Earmen Colibri.png

Note: Bass boost on.
Bass boost implies an increase of just over 3dB, between 10Hz and 150Hz, with a rapid drop down to 300Hz.

Sound

Note: For the sound description I have never activated the bass boost.
Earmen has used the same DAC as for his previous Sparrow dongle, the ESS Sabre ES9281 PRO. And indeed, the sound has very similar characteristics. But this time, I find the Colibri has a more distinct Sabre character, being more neutral and somewhat cooler. It is clear that the frequency response is completely flat and that the ultra-low output impedance means that the connected headphones are respected as much as possible. This is something that seems simple, but not all audio devices combine the basic parameters of flat response and very low output impedance. Earmen's devices do, and the Colibri is excellent in this respect. The result is a very clean, clear, crystal-clear sound, although perhaps a little thin in the mids and highs.
The bass has a technical nuance that adds precision and speed, generating a delicate, high-resolution texture that is far removed from an analogue feel. It's not that the sound comes across as harsh or digital, but it does offer a sense of perfection and restraint that is on the edge of naturalness. The level of depth achieved is undeniable and the Colibri will be able to handle the sub-bass with remarkable technical ability, endowing a speed and dryness of punch that will enhance the natural conditions of many IEMS. The sense of cleanness and accuracy in low end development is evident, generating a specific and thorough bass, whether from the SE output or the BAL output. The balanced output is even superior in this respect. Thanks to the great control the Colibri gives to the low notes, the lower range has a finite feel, limiting depth and expansiveness. Yet the perception of cleanliness, clarity and great technical performance add extra separation, layering and layering to the range. Undoubtedly, the Colibri improves bass decay, which is faster. In this way, transients are perfected and the interband zones are rendered well-defined and neat. It is clear that the low end is not the most analogue a source can generate, but if you are looking for bass with a clear tendency towards perfection, the Colibri is in that game. And the descriptive level achieved with it is likely to offer a different point of view, rich in detail and nuance, than other sources I am used to. Undoubtedly, it is a reinterpretation of the bass, endowed with an elevated richness, where textures, beats and physical sensations acquire a distinctive and very enjoyable dimension.
The mid-range runs along very similar lines. However, the Colibri's edge is slightly to the detriment of the corporeal sensation offered by the central range. The density of the midrange is restrained, so instruments and voices feel a little thinner. It's not that they come across as thin, light or bland, I think the more appropriate word would be delicate. Yes, the central band is still drawn with great precision and resolution, but its interior is subtle and fragile, yet at the same time complex and very descriptive. Both voices and instruments are completely imbued with intrinsic detail, forming an exquisite, light, glassy unity that takes on a sense of brittle vulnerability, but never breaks. It is in this way that a sense of clarity and transparency reigns supreme, as well as a stellar separation. The Colibri will be able to extract the tiniest nuances from the recordings and the connected headphones, all without falling into a totally aseptic, clinical or merely analytical sound. The difference is in the richness it brings to the music, in the sense of fragility and intrinsic detail that each note possesses. The effect of all this is a central band that is executed in a very pure and free manner, where there are no strings attached, the elements sound clean, very transparent, but never blurred, as there is no loss of musicality at any point. It is true that those looking for warmth will not find it, but neither will they find an abrupt or harsh sound, in any way. As I say, they will have to adapt their ears to a singular purity, full of idiosyncrasy, capable of providing a sonority worthy of the best fidelity, but with a different personality.
The highs of the Colibri are the result of the mature conjunction of a device with a high technical and analytical capacity, a high level of resolution, precision and splendid control. It is spectacular to observe how the high range is reproduced with a level of brilliance and finesse, without ever losing balance or musicality. The treble is drawn at that crossover point, between crunch and harmony. Really, the result is neutrality, but enhanced, augmented and extended. Little more I can say. The top notes are fast, they fade quickly, they have no aftertaste and their brightness is ephemeral. Moreover, they are perfectly defined and emphasised in their sweet spot, they have the finesse and delicacy of the rest of the bands and that is something that, for this band, has more positive consequences. In no case is it a sharp sound, and that is the best thing. No one range overpowers the other. The sound is balanced in that sense and each band uses its delicate power to bring out the best in itself, bringing its best qualities to enhance the musical richness and level of fidelity. This is how the treble is vivid, pleasing and expansive.
But if there is one area where the Colibri is not so good, it is in the area of three-dimensionality. While its level of separation is excellent, this does not help it to generate an ethereal and immersive image. The feel of the scene is quite frontal, with very good height. This aspect is surprising, and how the voices benefit from it. But there is no intimacy in the recreation either. The voices have a good sense of distance, without being congested by excessive closeness. In that sense, both the instrumentation and the voices enjoy that sense of freedom, transparency and cleanliness, which achieves a unique and separate identification within the image. But just as the width is vast, the depth is not perceived as exaggerated, nor is there a vaporousness that expands the elements on a three-dimensional level. It is as if the great capacity for definition were sufficient to fix the elements in their positions. On the other hand, thanks to this ability, the location of the elements is totally unambiguous. You can't have everything, but what the Colibri offers is highly enjoyable. Even so, the first sensation I had with the Colibri in comparison to other dongles, including the Sparrow, was that the sense of grandeur of the scene, which together with the excellent level of transparency and silence between elements, was a differentiating element of its high sonic category. The final conclusion is served, his scene is big, but it lacks an enveloping, steamy, three-dimensional level, even if its separation is almost exceptional.

Comparative note between SE and BAL output: Balanced outputs are almost always better. This case is no exception. Although I find the SE connection quite good, I am migrating the vast majority of my preferred IEMS cables to use balanced outputs. My feeling is that the Colibri's 4.4mm connection shows the true capacity of its delicate and smooth character, conjuring a wider soundstage, sharper separation and extra transparency. The differences lie in sensations that are hard to describe, but which make me feel better and enjoy the music even more.

Comparisons

Earmen Sparrow


The Sparrow is one of my favourite dongles and is my benchmark for comparison. Its sound level and power are quite impressive. It is worth remembering that, according to my measurements, through the 3.5mm SE output and at 33Ω, it delivers the same power as the Colibri. However, the Sparrow does offer 2V on SE and 4V on BAL. On the other hand, for the balanced output, the little Sparrow breaks the deck by offering 2V at 33Ω (120mW). Still, the difference with the Colibri is here: the big brother gives it all in the same conditions, reaching 250mW. Impressive.
Looking for the 7 differences in sound between one and the other can be very entertaining. In many situations, the behaviour is similar. But I find the Sparrow slightly warmer.
In the low end there is more substrate, body and density in the Colibri, as well as more complexity in its presentation. When headphones with good low-end potential are plugged in, the better descriptive ability, the more delicate and richer texture offered by the Colibri is revealed. The Sparrow's bass punch is powerful, but more concise, its development is simpler and not as expansive as the Colibri. This greater low end travel adds to its complexity, bringing a more flavoursome and lush feel to the Colibri's low end.
I think the Colibri's midrange is where the differences are most pronounced, in its favour. The sound of the Sparrow feels a little harsher and less refined. Whereas the Colibri achieves a point of superior softness and sweetness, without losing an iota of the technical competence it possesses.
The idea of delicacy is shown with greater emphasis in the upper zone of the Colibri, separating it from the greater roughness of the smaller Sparrow. It is clear that this continues to refine the Colibri's sound compared to its smaller sibling. The simplicity of the little one is also felt here and the Colibri is able to extend the treble a notch further, lingering a little longer in the ambience. Again, the Sparrow seems to have a faster decay, but this detracts from the descriptiveness of its representation. The Colibri's treble manages to recreate itself in a softer, but also richer and more respectful timbre.
In terms of staging I find the performance offered by the Sparrow drier. There is a touch of freshness in the Colibri that brings a superior vibrancy, something that offers superior dynamics and a greater sense of movement. This is how the image feels more realistic and somewhat superior. In terms of separation of the elements, the greater simplicity of the Sparrow limits the perception of a darker background and more obvious distance. The Colibri, with its greater sweetness and delicacy, has that point of greater resolution that widens the space between the notes.

Conclusion

I can't help quoting Miroslav from Earmen, in his presentation of the Colibri in the Head-fi.org thread: the Colibri is a Sparrow on steroids. Fortunately, this is not about adding such substances to a device, but about expanding an already quite good base: that of that little Sparrow. The little dongle was already a sound reference in its price range and adding superior functionality such as a volume control, a battery, on/off/play/pause control and bass boost only completes an intrinsically very good product. It is true that the aesthetics have been maintained and, in this respect, there is no major evolution. But there were few dongles as small and refined in this respect as the Sparrow, so what was the point of changing the image?
Successfully, the Colibri has two USB Type C inputs, one for charging and one for data. It has also opted for a balanced 4.4mm output, as is the current trend. It has limited its output voltage, but has increased its power compared to its smaller sibling, which is an achievement, demonstrating better performance in its electronic design.
In terms of sound, which matters most, the added steroids have not implied a higher level of loudness, but a greater delicacy. Technically, the Colibri is a step ahead of the Sparrow, it is also more refined and sweeter, achieving a higher and more noticeable value of definition, resolution and richness in the texture. In fact, the Colibri is a logical evolution within the Earmen sound: to add musicality and delicacy to a sound with an analytical tendency, to make it more attractive and universal, approaching a superior fidelity.

You can read my comparison of the EarMen Colibri and the iFi xDSD Gryphon on my Hungarian blog here.
Use Google Translate to read it in English.
My opinion:
The Colibri is excellent sounding device, it's SQ is very close tho the Gryphon!
Best genres are rock, jazz, electronic music, blues, pop.
For classical music Gryphon was a bit better.
However ergonomic design would have been better on the Colibri (e.g. button layout).

Reviewer at Ear Fidelity
EarMen Colibri
Pros: Great build quality
Neutral yet musical
Good value
Detail
MQA support
Pair great with most IEMs and headphones
Excellent case
Cons: The included cable is good quality, but it's basically useless (too long and stiff)
Rather big to use with a phone in your pants
Two USB ports impossible to distinguish with the case on

Introduction​

I’m going to start this review with a fun fact – We’ve reviewed three EarMen products so far, and ALL OF THEM have won Ear Fidelity awards. The latest one, a DAC called Tradutto hasn’t been moved from my desk ever since I got it in November 2021, and that’s really something.
So, today we’re reviewing a new EarMen product, so we should expect another extraordinary device.
The market for dongles is constantly growing and more and more people get to use dongles on the daily basis nowadays. While I’m more of a DAP user myself, I’ve bought the new MacBook Pro lately, so a dongle was definitely a good idea to get. While I can’t call the Colibri a “classic” dongle because of its size, it’s not a stationary DAC/AMP either, so…dongle it is for now.

Packaging​

P1050974-scaled.jpg

The unboxing experience of the Colibri is good. It comes packed in a rather big box that is well-made and quite aesthetic. Inside, apart from the Colibri itself, you’re getting an artificial leather carrying case that is protective and nice feeling. It’s not too tight nor too loose, giving you a good sense of confidence while handling the Colibri.
P1050978-3-2-scaled.jpg

Next up, you’re getting a USB-C cable, which is a bag of mixed feelings for me. It is really well-made, but it is rather long and stiff, which makes it hard to use with laptops and just a pure horror with phones. For the cable to be usable in the use-case scenarios of this DAC, it should have been a lot more flexible and less stiff.

Design and Build​

DSCF6107-scaled.jpg

The build quality of the Colibri is (as we’re used to with EarMen devices) fantastic. It uses premium materials such as a full aluminum block miled on a CNC Machine sandwiched by two glass panels.
As for the design – it’s a dongle, and it looks like a dongle. It is really big for this kind of device, making it rather hard to use in a pocket with a phone without sticking them both together. As for using it with a laptop, its size is more than comfortable and just simply not a problem at all.
The Colibri is battery-powered, which means that a vast majority of its internals is occupied by a large battery. This gives us two USB ports, one for charging, and one for audio which is not super convenient, as you have to know which one is which (the label is on the back glass panel and you’re not able to read it with the case on). It would have been better for EarMen to use colors instead.
On the top, you’ve got two headphone outputs, a 3.5mm and a balanced 4.4mm output. No 2.5mm balanced, it’s finally dying and fading away, good.
On both sides of the Colibri there are two buttons for changing the volume, switching the bass boost, and turning the Colibri on/off. Lastly, this device is Made In Europe.

DSCF6100-scaled.jpg

Tech​

The Colibri uses an ES9281 PRO DAC chip, and here’s what EarMen got to say about it:
“The heart of the Colibri is the flagship of the ESS line ES9281 PRO DAC. The ESS SABRE PRO series is for premium audiophile and sets a new benchmark in high-end audio by offering the highest dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N). Colibri supports Hi-Res PCM files up to 32bit/384kHz PCM, DoP, DSD64, DSD128 and MQA . In short, all in one solution.”
The Colibri can output up to 280mW into 32Ω which is rather impressive for a device of this size with a built-in battery. While it won’t be enough for hard-to-drive planners, it surely is powerful enough for most IEMs and many headphones.

Sound​

P1051006-scaled.jpg

Okay, this review has been pretty straight to the point so far. This is because I believe it’s a rather simple device both in terms of its design and functionality. Let’s jump right into the sound paragraph now.
The overall presentation of the Colibri is neutral and engaging at the same time. I believe that EarMen has mastered this kind of sound signature with their portable devices like the TR-Amp, Eagle and now the Colibri.

The bass of the Colibri is linear and neutral, but thanks to the addition of a bass boost, you can make it more physical and powerful with a single click of a button. This is a great option to have, especially in a device with neutral tonality. This gives you an option to slightly tune the sound to your liking.
No matter if you turn on the bass boost or not, you’re getting a highly technical, fast, punchy, and detailed bass response, just a different quantity.
The midrange is very neutral and universal, but not the most engaging. While the Tradutto has an absolutely beautiful and lush midrange presentation, the Colibri is much more technical and analytical sounding. Luckily, it’s not harsh or boring, giving you an exciting and quite fresh type of sound. One of its biggest strengths is definitely the sense of dynamics, with its grandiose note delivery and ability to get really dynamic.
The treble is the aspect that is rather controversial in most of the devices similar to the Colibri. I just feel like such a portable and small device cannot output a really high-quality treble response, and the Colibri partially confirms that. Partially, as it is really detailed and it offers great resolution, but it’s a rather thin and not tonally correct sounding when compared to some high-end equipment. However, for this kind of device, it still sounds marvelous.
If you’re somewhat used to EarMen’ devices then you’re probably aware of the fact that they really know their stuff when it comes to the soundstage. It’s not a surprise that the staging is the biggest strength of the Colibri, tied with its detail retrieval. It offers a natural, airy soundstage with great imaging and separation, something that doesn’t sound like a dongle whatsoever. Pair it with a good staging IEM like the Unique Melody MEST and you’re getting a really fantastic soundstage delivery worth of being called extraordinary.

P1050996-scaled.jpg

Okay, before you go all nuts on me for comparing this $300+ USD DAC/Amp to a laptop, hear me out. The newest MacBooks sound absolutely great for a laptop, and they should have always done that.
So, is the Colibri better in terms of the sound quality? Yes, it is. It’s more detailed, faster, meatier, and has better staging capabilities. Is it worth getting the Colibri if you have the 2021 MacBook? I would say definitely, I definitely use it whenever I feel comfortable with it, craving for that better audio quality over the onboard (and a really good indeed) DAC/Amp.
Cayin RU6

DSCF3914.jpg

These two really trade blows a lot. They offer a completely different approach to tonality, resulting in a totally different type of experience.
The RU6 is all about its timbre, warmth, R2R-ish texture, and sweetness, it kinda sounds like a pillow.
The Colibri on the other hand wants to take you dancing, and it won’t be a slow one…you’re getting in Pogo style, quick and aggressive.
I would say that they both play in a similar league when it comes to the technicalities, with the Colibri slightly edging the Cayin mainly due to its tonality. While their power ratings are somewhat similar, the Colibri has more meat to work with harder-to-drive headphones. It handles the Arya SE beautifully, which I would not say about the RU6. They’re different, choose what tickles your fancy, you can’t go wrong with either, or both actually.

Thanks to its technical and neutral character, the Colibri pairs well with most IEMs, except the most aggressive and bright ones (don’t plug Cayin Fantasy into it…please). Its detail retrieval and resolution do wonders when paired with high-end IEMs. The Colibri actually sounds fantastic with my new Fir XE6, a $4000+ CIEMs…
As stated previously, it works well with some over-ear headphones as well. The Hifiman Arya SE, Meze Elite, Edition XS all sound great when the size of the Colibri is regarded.

Summary​

DSCF6096-scaled.jpg

The EarMen Colibri is a really good-sounding device, but its size and functionality put it in a somewhat weird category. Too big to be a true dongle, too weak to rival the best portable DAC/Amps…and it paradoxically sits in a sweet spot. It’s just perfect for business trips, hotels, and laptop work on the go, giving you a significant boost in audio quality while taking next to no space in your backpack/suitcase. It is just that for me. I travel with my backpack that has a lot of things inside, like my camera, lenses, laptop, gimbal, hard drives, etc. The Colibri takes literally no space inside, and it just gives me that great audio performance whenever I’m in the mood for some music.
Gear used during this review for the sake of comparison and as an accompanying equipment:

Big thanks to EarMen for providing the Colibri for this review. I wasn’t paid or asked to say anything good or bad about this product, all of the above is just my personal, unbiased opinion. EarMen hasn’t seen this review before publishing it.

@Sphere 57 I had a hard time deciding whether to call it a dongle or a DAC/Amp, does the lack of battery make it not a dongle? Don't know the terms of naming it :D

There are no rules I suppose. Earmen call it a DAC/amp, which is what they also call their 'Eagle', I would call that a dongle. Maybe strictly speaking a dongle should have a built-in cable?

Dongles must always dangle, but is everything that dangles a dongle?🙂
