AudioQuest Dragonfly Cobalt USB Digital-to-Analog Converter

I will start this review by saying that I am not an audiophile. I very much enjoy good music and high quality audio, but I think that spending upwards of 1000 on a product that gives you an extra 5% performance is silly. So when I found the Dragonfly DAC in a variety of Audiophile magazines I was intrigued. The Audioquest DrogonFly DAC is a very interesting device. Much smaller and more portable than a standard DAC, but supposedly built with the same high fidelity bits you find on much larger tabletop DACs even including a headphone amp and an analog volume control. In my findings, this DAC performs admirably. The speakers I'm powering are a pair of Paradigm Shift A2s. In terms of build quality this thing is built like a tank. I have a large number of thumb drives (Although no waterproof/tough style drives) and this thing feels far more solid and robust than any of them. The included cap is nice, although like most thumb drive style caps it's quite easy to lose. The packaging that it comes in is very nice and indicates some serious thought was put into the product. It's shipped in wrapped in a velvet-esque carrying case, inside high density foam in a double cardboard box. I'm fairly certain you could drop this thing out of the delivery vehicle on a freeway and run it over a couple of times and it would still be in perfect condition. I've put it through the ringer with a large variety of music from pop streamed at 128kbps from Spotify, to classical 192/24 FLAC files. In all counts the DAC has impressed. I found it nice and neutral, just like a good audio device should be with no particular character other than very clean precise music. Coming from an onboard soundcard (albeit a decent one on a very high end motherboard) there was a world of difference. As cliche as it is, I heard details I'd never heard in a variety of tracks and everything I listened to seemed much more precise. I also enjoyed enhanced soundstage that was helpful in FPS games to more accurately locate the location of enemy footsteps. I have two complaints, both of them fairly minor. First and foremost, The connector worries me. I work as a Custom installer doing audio systems, and one thing I've learned in my work is never trust a mini-jack. The connectors are flaky at best and it's worrisome to see it included on a $200+ piece of equipment, especially one where it's likely to be plugged and unplugged on a regular basis. That being said, the build quality is fantastic, the thing feels like a tank, so although I'm wary of the connector, until I get evidence to the contrary I have no reason to believe it will be damaged. My second complaint is that with my initial unit, there was a fairly serious issue whereby the USB connector seemed to not make contact unless there was a significant amount of pressure on the DAC. I believe this was either an early production issue, or possibly just my sample, however it was extremely annoying. At best, my sound would cutout every time the pressure on the DAC was released, and at worst, it would make horrible popping noises that sounded as though they were desperately trying to blow my speakers. The constant pressure required on the USB ports on my computer worried me with regards to longevity. After some fairly substantial searching I was unable to find many similar complaints online, so I must assume that it was either limited to a very small initial run or people aren't speaking up. Given that this is the internet I'm forced to conclude the former. That all being said, after a couple weeks of searching to see if I could possibly resolve the issue through software, I contacted the company and they informed me it was a defective unit that should be RMA'd. I live in northern California near the Oregon border and after sending it out the new unit arrived within a bit less than a week. Given my difficulty tracking down similar issues with other purchasers, I believe this was a short term problem and I believe any currently selling models are well past having this issue. The replacement unit they sent me works perfectly and I've had 0 issues with it at all. Overall I have been very pleased with this DAC and I would highly recommend it to anyone looking for good, portable, reasonably priced sound.

What’s Old is New Again. All the reviews out there in the blogosphere/vlogosphere that tout the Dragonfly Cobalt and its ability to enhance your listening experience are overwhelmingly positive, so you can certainly look up any of those reviews from an expert’s point-of-view. But from an Average Guy’s view (like me), I can definitely hear the difference when using this device. I tend to listen to music in my car more so than any other place. And, for that, I usually stream music via my phone (Amazon Music HD) through the car’s AUX port. I have been doing this by simply taking a high quality 3.5mm audio stereo cable with two male heads and plugging one head into the AUX port and the other into the phone’s headphone jack. I own an LG G8 Thinq (the last flagship phone LG made in 2019 prior to exiting the smartphone segment; and this phone features that rare headphone 3.5mm headphone jack). Back then (and even today in late 2021), that in-phone DAC was generally regarded as the best by quite a margin (the phone’s max sample rate output is 24-bit / 48 KHz). Meanwhile, I own a 2014 BMW 3 Series and I have done lots to improve its musical components. I’ve upgraded my amplifier (Up7BMW) and all speakers/A-Pillar tweeters (FOCAL brand). And, I purchased an Equalizer app on the Google Play Store. Still, wanting higher fidelity, I then purchased the Dragonfly Cobalt DAC. Immediately, even with all of the upgrades that I’ve invested into my car’s sound system, I could hear a musical boost. And when I play my favorite songs, old and new, the enhanced fidelity peels back all of these musical elements that I had never really noticed before (a more pronounced drum beat; the sliding of the fingers along the neck of a guitar; the raw emotion of a singer’s voice; better defined strumming from a generally-hard-to-notice acoustical guitar, etc… - what audiophiles would describe as neutrality). I’ve read various articles stating that listening to your radio does sound muddy, which it does. You can (and I can) hear a difference when playing a CD. But, adding a good DAC takes it up one notch further, and you feel like you’re right there in the front row of a concert or at the recording studio itself. Now, your listening experience may differ because not everyone “hears” the same or perhaps as well. So, if seeing a number helps you to visualize improvement (although “seeing-is-believing” is different than “hearing-is-believing” in this case), here’s what I’m seeing with my LG G8 ThinQ. Without the Cobalt, the phone’s DAC can stream music at up to a sample rate of 24-bit / 48 khz, which is pretty good. I know this because with Amazon Music HD, you can press the music quality “badge” to bring up this kind of info. Now, with the Cobalt plugged in, the output increases to 24-bit / 96 khz. I’ve read that the max output, though, would be 24-bit / 192 khz, so let’s quickly talk about that pinnacle of sound quality for a second. The only way of possibly getting there from my readings (and I’m sure there are other ways that I haven’t discovered yet) is by subscribing to Tidal’s HiFi Plus Tier (which is their top tier) AND also downloading onto your phone an app called USB Audio Player Pro (also known as UAPP). Somehow – and I profess my ignorance on this as I’m not a sound engineer – this app plus the Dragonfly Cobalt plus its ability to play well with Tidal (the technical term sound engineers use is “unfolding”) allows access to that 24-bit / 192 khz musical experience Anyway, as you’ll already know, the Dragonfly has this helpful light that defines the quality of the music you’re hearing. Unfortunately though, unless you’re paying $240 a year for Tidal’s top hi-res tier, that light then also gives you a sense of FOMO. I pay $80 a year for Amazon Music HD (as I am already an Amazon Prime member). Now, for just $80 a year and despite not being able to reach that 24-bit / 192 Khz threshold, I can still attain musical nirvana. So, Amazon Music HD is totally worth it. And the Dragonfly Cobalt, IMHO, is totally worth it too. But, as with all things subjective (like hearing), your mileage may vary. Will this be worth it to you? In this case, there are four things that you’ll want to consider A) Can you hear the difference? Again, some of us have better hearing than others. If you can’t hear much the difference between music over the radio and music on a CD, then you probably won’t hear much of a sonic upgrade here. B) How many hours a day will you use this? That is, why purchase a pricey doodad if you’re only going to use it now and then? It’s kind of the same in-your-head argument when you think about joining a gym or subscribing to Disney+. C) Think about your music source. The idea of a DAC is to allow it to further “unwrap” the audio file to allow for that richer listening music (again, using that term “neutrality”). But, if you’re listening and happy with Spotify Free or any other lossy music tier (usually the free ones with possible ads), those files won’t have much to reveal anyway. The entry point at which to consider whether to invest in a DAC or not is when you are subscribing to a hi-res music service (i.e.: Quboz; Amazon Prime HD; Tidal Hi-Fi; etc…). D) Finally, think about the equipment that will be outputting your sound (e.g. earphones, earbuds, speaker systems). If they are of low quality, then a DAC probably won’t do much. And keep in mind that this DAC would also probably cost MORE than most run-of-the-mill earphones, earbuds, speakers). Oh, I do want to bring up one thing if you subscribe to Amazon Music HD. I saw on their FAQ page that Amazon Music HD is not always reliable in giving max audio quality if it doesn't sense a super-fast internet connection (or maybe if a lot of subscribers are trying to stream hi-res music at the same time – let’s call it ‘congestion’), so I’ve seen the light turn both powder blue (denoting a bitstream of 96 KHz) as well as cobalt blue (denoting a bitstream 48 KHz for the same song during different times of the day, but never below that number if you’ve set songs to play at HD or better quality). In fact, on its FAQ page, it does say, “For streaming, the current source file quality may change due to varying network conditions.” So, if you’re subscribing to Amazon Music HD and see this happening, it’s not the Cobalt malfunctioning. Finally … here’s a question you’ll want to ask yourself and a suggestion. Have you looked at the THX Onyx? It is also a very well-regarded DAC and probably a 2nd place runner-up if you read the various reviews out there about DACs (with the Cobalt being the consensus winner when talking about power/portability). However, at the time of this writing, the Onyx is currently on sale for $150 (down from about $200, and can be found here on Amazon or on Razer.com). Hmmm… $150 for the Onyx vs $330 for the Cobalt? That does make the Cobalt a tougher sell, actually. Again, the only real downer here is the price. $330 seems pricey, even though it’s a svelte yet powerful top-of-the-line product. If you are willing to consider really good dongle DACs with perhaps less of a svelte/compact form factor that cost just half as much, you may also want to check out these very worthy alternatives, also found here on Amazon. - THX Onyx, $150 - Helm Bolt DAC, $150 - Astell & Kern USB-C Dual DAC Cable, $100 In the end, the Dragonfly Cobalt is a 5-star product (although I’m not convinced that it’s $150 better than the THX). I’m very happy with this product. If you tend to listen to music quite a bit to complement your day, then investing in a really good DAC like the Dragonfly Cobalt makes for a solid purchase decision. Good luck on finding what suits you best.

I discovered the audiophile world (or rabbit hole, depending on who you ask) several months ago, and have enjoyed trying various headphones + DACs/AMPs + hi-res tracks over that time. My goal is to (1) find combinations I like and stick with them vs endlessly salivating over things I don't own, (2) find good values that fit my lifestyle and make common sense (e.g. no telling my kids they can't go to college because I need new headphones, but also not fooling myself into thinking a $20 pair will somehow sound summit-fi) and (3) never become the guy who uses snooty "audio sommelier" terms I read all too often on message boards. In the DAC/AMP world I've already gone through the Fiio Q1 (was fine, but didn't really do much for me) and the OPPO HA-2 (looked super slick -- made everything louder -- but ultimately was too harsh/sterile in the treble dept). I've lusted over the Chord Mojo for quite some time and would love to listen to it. I have no doubt it sounds great! But my fear is that it won't sound "$600 great" to me (see point #2 above). And then I stumbled across the Darko review of this new Red just a few weeks ago and knew I had to try it. I'm playing it through an iPhone 5s connected via the Apple CCK (using Onkyo HF Player), an iPod Touch 6th Gen (through Korg's iAudioGate) and also through my Macbook Air (using Roon). Set-up is super duper quick and intuitive. Audioquest did a really nice job in including a detailed booklet written for the layperson, telling you everything you'd need to know (and why, which is sort of cool in the audio world -- too many companies treat you like you've already got a Master's Degree in HiFi Audio). Extra bonus: Audioquest ALSO threw in a nice travel pouch + a coupon voucher to HDtracks + a 60-day complimentary trial to Roon (this is super nice, as the trial period from Roon themselves is just 14 days). If you haven't read up on Roon I'd highly recommend it --- it allows you to play higher res tracks on your Mac computer...it's a lot more fun/intuitive/exploratory than the native iTunes player...it integrates with Tidal...and it absolutely makes your music sound better. Same thing with Onkyo HF Player for your iPhone. At any rate, let's cut to the chase. How does the Red sound? Quite good -- IF (1) you have good headphones, and (2) you're taking advantage of better sources (like the players I described above). If you don't do any of that, it will make your music sound louder but not necessarily a lot better. I'm using HIFIMAN HE400s, which are great reviewed/open style/planar magnetic headphones. They're efficient already so don't necessarily need an amp, but most everything sounds better with an amp. Anyway, if you're curious how exactly the sound improves with the Red, here's my best way to explain it: more full, and more realistic. Picture a comb -- imagine that this is a visual representation of your music without a DAC/AMP. Now, imagine that all those tiny spaces between the teeth of the comb get filled in -- this is the DAC/AMP going to work. It feels like it fills in gaps/missing info/details you didn't realize were there, so overall everything sounds a little louder/clearer/lusher/more realistic/more enjoyable. There's more bottom end to kick drums...more "plucking" you can sense on guitars and bass notes...more snap on snare drums...and little things like hi-hat cymbals suddenly sound real, vs a digital copy of what's real (if that makes sense). Also, there's more separation between instruments, creating the "space" that you read about, so it feels like you're in the studio surrounded by musicians rather than just being presented a wall of sound. I did an A/B test of a rock song I'm familiar with, listening to identical sections with and without the Red. Without, I found that the bass guitar disappears into the drums...sometimes you'd hear it, and sometimes you wouldn't (would just be sort of muddy). But with the red, there is a distinct bass guitar playing alongside a distinct drummer playing. Don't get me wrong -- the overall effect is not a massive night/day difference that bowls you over -- so don't go in expecting that or you'll be disappointed. Instead, if you take the time to get good copies of music + good headphones + good sources, then you WILL take notice of the improvement and enjoy the positive contributions the Dragonfly brings and you'll want to listen to more of your music. Also, geeky cool thing that's actually helpful: the dragon on the device glows and changes colors, to tell you what sample rate your music is. BOTTOM LINE: Sound is superb. Value is great. The care they put into the booklet + add-ins are nice surprises. Convenience is top notch. And the fact that it is pretty future-proof (they designed it to accommodate firmware updates) is great. If any of the above describes your philosophy, I think you'll really enjoy it. --------- UPDATE 1 MONTH LATER: I was going to be eternally curious about the CHORD Mojo, so I went ahead and decided to audition that as well. I spent about a week with it, and my 100% honest-to-goodness takeaway was: I personally could not hear an audible difference between the DragonFly Red and the Mojo. They both make my music sound better, but neither one is better at making it sound better (to my ears, anyway). I'm sure there are measurements or tests or something that prove Mojo "wins"...but I couldn't pick up on it. I have no clue if that's because there IS no discernible difference between the two, or my equipment isn't good enough to reveal that difference (although I use Hifiman HE-400s, Westone W30 and Audeze Sine, all of which is a far cry from entry level gear) or my ears just aren't "golden" enough to tell. Who knows - I'm sure others swear they can tell one from the other. At any rate, Mojo definitely sounded great....but so does Red. And Red is 1/3 the cost, firmware upgradeable, much more discreet/portable and never requires charging (I already had one annoying instance where I sat down to listen to music, but Mojo's battery died 10 minutes later and had to be recharged for 3 hours). Thus, I returned Mojo and am keeping the Red.

I like the sound quality, added volume, and portability. This replaces my dragonfly red that failed. I bought the warranty for it and with the credit I replaced it with this. I use it inline with my iPad going to a klipsch 2.1 computer speakers in the shop. The headphones at home I used on this Dac and the Dragonfly red were Sennheiser 599’s. My son upgraded his Dac(to an RME ADI-2 pro) and headphones (to Hifiman). While my dragonfly red was out for repair, I got a chance to use my sons older set up - a jds labs element 2 and Sennheiser Hd700’s. I can tell you with certainty, that these inline amps are for different needs than the dacs that require external power source. The lack of an external power source or lion battery will limit amplification, especially higher impedance headphones - there just isn’t enough required voltage to drive the internal amp louder. IC companies are getting much better at providing an op amp that has more gain with the same audio input level than earlier op-amps. This means you get more volume with the same signal level. This is the path Audioquest has chosen. You’ll need a USB A female to USB C adapter or USB A female to lightning depending on your mobile device. See my pic, apple camera adapter. It allows me to keep my iPad charged while I play it. It doesn’t give it any extra juice for amplification. There are portables that you have to charge first and it plays on battery power - IFI has some I would love to try. I know many people claim they don’t hear the difference or can’t hear the difference between internal vs external dacs. OR they can’t hear any difference even with 44k streaming - internal Dac vs external Dac. My dad is 83 and we did many AB comparisons with straight 44k and even these Dragonfly’s are better than OEM apple dacs. I know they use good stuff, but I can easily tell the difference. I can’t speak for the Cobalt version (Blue), but these inline dacs are made for portability, louder, and better sound - which they do. Where these dacs come into their own is 88k sampling and above. Try a streaming source like Qobuz or such and download some hi-res version of the songs that make these thing shine. Streaming an 88k and above is an issue due to how big the file is. Downloading eliminates buffering. I get a warning on Qobuz that lets me know I’m not allowed to play a hi- res version without downloading it first. Maybe if I had fiber internet it wouldn’t be an issue. The difference in what a Dac can do for you is best described by the day I got my first HDCD transport. When a drummer hits a cymbal during a soft part of the song - how long do you hear the ring. With cheaper dacs and smaller sampling 44k and lower, there is data missing from the original recording - the cymbal decays quicker. Us old farts that love vinyl are attracted to high sample rates and lost-less files. We each prefer or dislike certain types of files or recording options. Sound is as subjective as food, colors, cars, and friends. Again if you don’t hear the difference, don’t hate, just save your money for something else ;) Happy listening.

Lets face it, if you have an iPhone you have to buy this. It's the only DAC that can operate off of the iPhone's power and with the new iPhone 7 you have no headphone jack. Audioquest knows this and moved heaven and earth to implement the Dragonfly with chips that use a third of the power to avoid tripping the Apple "Alarm" that says you're over the power limit. First of all, Dragonfly is a DAC/Amp/Preamp made by a cable company NOT a DAC or amp company. Yes, the prophet of Asynchronous USB DAC and genius Gordon Rankin designed this. Amazing technical achievement, but I have been comparing to the Fulla DAC/headphone amp by the notorious Schiit company (no, I'm not joking) and the Fulla sounds better on all bitrates than the Dragonfly. Best of all, It only costs $59 as they move to a new model for $99 that has the power connector built in to work with iPhone and USB outside power. It also has... a round knob which is an analog volume control! Dragonfly has problems with volume control since there is no little round knob. To test, I used several pairs of my favorite Audio Technica earbuds, GrandVela earbuds, Grados, and Sony MDR reference headphones to really find the flaws. Bottom line audiophiles, the Dragonfly on iPhone STREAMING (Tidal, spotify) music has the dreaded "glare" at high ends that makes listening slightly tedious. Glare means highs sound "bright" not warm. This disappears on Lossless music where the Dragonfly really shines. I mean SHINES. It's much better than Apple stock audio out which is produced by chips the size of deer ticks. Face it though, if Apple wanted they could dump R&D into audio and beat everybody. They don't care though. If they did, they'd offer 24 bit master quality music on iTunes. Next, I plugged the Dragonfly critter into my Windows laptop and had significant volume control issues with JRMC (JRive Media Center) where I could only raise the volume to three pecent before breaking my eardrums. No matter what controls I used fixed this. I then decided to turn on the pricy Signalyst HQPlayer software which is the gold standard of computer audiophile software. After listening to some amazing 24 bit Chopin Noctures I really started to dig the Dragonfly. The glowing bug on the black stick turned purple to denote me playing lossless audio. Wow did it improve the sound. The glare was gone. I listened to 24 bit Led Zepplin IV and it was great too. I'm listening to 16bit FLAC Coldplay now and it sounds great. The volume control also works really well in HQPlayer. A word on Dragonfly Asynchronous USB technology developed by Gordon Rankin. The reason you MUST have a DAC/Amp with Asynchronous USB is because computers aren't built for sound. The "clock" that determines how the music is put together into a coherent pattern is all over the place and causes unlistenable muddiness to those of us who use USB DAC's for our digital music. Example would be Coldplay In My Place where the cymbals sound horrible on a computer sound card. They still aren't great on a good DAC, but they are listenable. Audio is much different than image or video quality. Top computer hardware companies throw their tech engineering dollars into screen quality, not audio quality. It's why it's taken so long for audio to catch up. People just aren't picky about sound - until recently. (Also the reason people still buy crappy Beats garbage.) If you really want AMAZING sound from a miniature USB DAC/amp and don't care about iPhone power issue, get the Fulla by Schiit and buy Schiit products. The founder is the actual inventor of the DAC back when he worked for Theta in the 90's. If you have $2200 he makes the finest DAC on the planet. That knowledge trickles down to their lower models like Fulla and Modi. Their attitude as a company is anti-corporate. You will love them. Audioquest is great at marketing. They broke the mini-USB barrier. Buy this. I'm not giving it a five star due to the sound on lossy recordings and the fear that if I fall asleep and my laptop falls on the floor I will permanently damage the USB jack and break the Dragonfly. I'm buying an Audioquest cable to give me peace of mind on this issue very soon. Please start listening to lossless FLAC audio, get Tidal HQ service and turn yourself on to the dream world of digital music. Forget Vinyl, it's a complete joke compared to Computer Audiophile setups with high bit digital music. Vinyl is for people who think Birkenstocks are high fashion. Try different audiophile grade software packages. You will hear more sound quality difference on software than DACs. All Async DACS are good these days. Even Dragonfly. Finally, I decided to listen to the 24 bit Chopin Nocturnes on free software called Bug Head Emperor from a very strange Japanese genius. It's somewhat challenging to use and you need freeware Asio4All installed and set to use the Dragonfly. The Nocturnes sound magnificent and turn the Dragonfly a mellow orange color. Set volume to 14 or half the Max or have your eardrums shattered though. I can hear the pianist breathing on these recordings. Try hearing that out of your garbage headphone jack. Cheers! Update: Tidal which is the lossless music service owned by JayZ competing with Spotify has just released MASTER 24bit/96 streaming today. I've been doing extensive listening tests with the Fulla DAC/amp vs the Dragonfly. The Fulla kicks the pants off of the Dragonfly on sound. I've spent the past two weeks since Xmas with the Dragonfly every day, but there's no comparison in sound quality. I still love the Dragonfly because it beats out the stock tick sized DAC chips in phones, but the Fulla really shines even with it's faults. Get both.

Highly recommended. I bought the DragonFly to use as a headphone amp/DAC for use with my iPhone / Shure 535's while on the go. I stream Tidal lossless (CD Quality) and sometimes Spotify. Without the DragonFly, the sound sounds good over iPhone / Shure, but there is graininess across the spectrum - instruments lose their juiciness, the sound is a bit compressed and the music gets tiring after 30-60 minutes. Enter the Dragonfly, and the music sounds clear, emotional, juicy, transparent - and I can forget about the annoying graininess, and enjoy music for upto 5-6 hours at a time (on a recent long haul flight). The Dragonfly is the perfect portable DAC. It's small and plays from your back-pocket hooked into your phone. Does not require extra batteries - does not drain your phone battery and tips the sound quality of your portable system over to the audiophile side. It does NOT sound like a MOJO DAC, which elevates the music to an even more nuanced / finer accuracy and realism - but it doesn't matter - because the Mojo doesn't fit in your back-pocket. I recommend this device reservedly to anyone with high-end headphones costing over $400. For anyone with headphones less than $400, save your cash and buy better headphones - they will make a bigger difference. But hook a pair of great headphones straight into an iphone without a DragonFly and be warned, you are missing out! Is it good value for money? YES! I am lucky to own a pair of open Grado PS500e (astounding headphones). I also use a Mojo DAC (at home) and I occasionally listen to my headphones over a Brooklyn DAC which is also hooked to a $10,000 stereo. I have a good point of reference in terms of what a good audio component should sound like, and at what point spending money on sound has diminishing returns. The Dragonfly represents incredible value as a portable headphone DAC/Amp. I have never spent $200 on an audio component that gave me so much enjoyment. Is it better than X,Y,Z? It doesn't matter. It sounds better than you'll ever need for music on the go - you'll need to be critically listening to tell the difference between this and a $2000 DAC on in-ear headphones - and you can't carry a $2000 DAC with you. So what's more important is how practical it is vs it's competitors - and what does it cost. My advice is - buy this one. It is the benchmark of portable headphone DACs, you won't miss the $50, and you will not have an upgrade itch because you bought the best. Note 1: Many people buy this device as a stereo DAC - I haven't bothered trying it on my stereo because I will never use it as such. Note 2: I haven't compared this extensively against the Mojo. During 1 hour of comparing it against my Mojo at a store, when played back to back I found the Mojo to be significantly more realistic on my favourite songs - but I never missed the Mojo when I travelled for 10 days abroad listening to the Dragonfly. Instead I was liberated from cables and from charging yet another device. At home, the Mojo is the amp of choice. Note 3: The entire review is based on my experience with the Shure SE535 headphones. I have not done extensive listening with the PS500e Grados'. The Grado's might be more revealing to the DragonFly's short-comings vs the Mojo. Again that doesn't bother me because the Grado's are "open air" and that doesn't work outdoors - so the comparison is pointless.

Where shall I begin? I am an audiophile, I truly love sound, I care for the quality of sound, music is so important in my life. I have a dedicated portable music transport and separate portable dac, but it becomes too much to carry around or to even travel with all the time or to go to the gym with or to even go for long walks with and I'm just too damn old to even carry it in a separate bag. So I decided to purchase a dac for the phone. I first started with the Black, which was a slight decent upgrade, but not what I needed. I borrowed a friends red, and that was a beautiful upgrade, nice warm sound, and then I bought the Cobalt (blue). I was amazed and disappointed at the same time. First, this truly upgrades the sound beyond what I had expected, the sound separation was mind blowing, the bass, treble and mid range were all separate close to perfection. When it comes to this dac, you must match it with a good pair of headphones or in ear buds. I used it with Bowers and Wilkins in ear and headphones and it was a great experience to a certain extent. What do I mean by certain extent? Well, once you pass the midway volume point, it begins to sound distorted due to the volume being so loud coming from the dac, listening to it at low and mid volume you will get perfect sound, but raise it up past the mid-level volume it sounds over bearing at times. Now, the build quality is great, it's smaller than the black and red. Quality of product? I had to return two of them, the first one I ordered had static on the left side, the second one I ordered had a strong loud whining sound that came on every 20 minutes. It was so loud that it would have caused hearing damage if I was listening to it at a loud volume. When looking into these issues, it seems to be an ongoing issue for many years. I guess it's hit or miss when buying this. I've read reviews that it isn't for every kind of music genre. I disagree with that statement, I listen to everything, from house and club music which sounds excellent with this dac, to listening to lossless files of Beatles and Elvis Presley music, to classic rock, classic instrumental jazz, old school hip-hop and so much more. And the difference is stunning. I'm not sure what the issue is with it being so loud to the point of being overbearing, which if you look online is an issue, to the static and whining sound which is also a known issue. Although Audioquest has a great return and replacement guarantee, it defeats the purpose of trying to trust this brand with quality control. Is it worth $200? It is if it didn't have these issues, I think the upgrade in sound that it gives you is worth the price. Is there a difference between this one and the red? Yes, the separation and detail within definition is better on the cobalt, however, if you like warmer sound similar to listening to vinyl records, I would go with the red. If you really don't care much for sound quality and want a slight improvement in sound, go for the black. But if you are someone like me that really cares for sound, and sit back and listen deeply to music, the red and cobalt are your options. If you really want to listen to definition and detail, and hear things you've never heard before on a song, the Cobalt is your go to. I will give you some examples. Pearl Jam - Rearview Mirror, at the very end of the song you hear the drummer throw the drum sticks on the floor in anger, you hear the sticks hit the floor in full detail. Pearl jam - Black, you hear the piano clearly separated which is beautiful and makes you feel the emotion of this song even deeper Mile Davis - kind of blue, you can hear this man breathing each time he blows a deep note, it's so powerful. Elvis Presley - Big Boss Man, the separation of the instruments brings you closer to the song, hearing the band truly jam hard on this track makes you realize that Elvis did indeed pick the right band members with the way they are playing. The cobalt is worth it, especially if Audioquest fixes the issues that it has... One last note, I've read reviews of people saying to use it with the jitter bug, do not! It diminishes the sound quality, the cobalt does not need it at all, the black does as it makes a difference with that one. So I give it a solid 8 with the volume being at low to mid, then I give it a 5 with it higher than that.

First of all, my setup relevant for this review is iPhone 7 Plus & iPad Pro, V-Moda Crossfade M-100 wired/wireless headphones, audio source a mix of Apple Music (at 256), audio podcasts (below 256) and a touch of some songs ripped from CD into Apple Lossless format. I have always been on teetering the fence on whether to go the route of the portable external DAC. Carrying around a digital media player is far too inconvenient an option for me, and the DACs on the market were either too bulky, pricey or battery intensive to make the switch. As rumors started circulating of the 3.5mm port's demise on the iP7 started floating, I starting looking around again and found this gem. The Dragonfly has met my expectations, and I would say even if you have a device with a traditional 3.5mm port, it is worth using this anyway (supported easily through any Apple device with a Lightning port and USB Camera adapter - sold separately). Now getting into the experience... Setup and form factor/convenience is a slam dunk here. The device itself is literally just the size of a thumb drive and is actually pretty stylish. The green dragonfly on the front is actually and LED status indicator that basically let's you know when the device is on standby, or when in use, the quality of the content playing (green, blue, amber for example for different quality levels of source content). Since tons of people will now be walking around with the apple 3.5mm adapter, explaining what this "fancy" one is may be a source of a brag moment for some audiophiles out there. Setup on any Apple device is literally plug and play. One end into the USB camera adapter, the other into your headphones of choice and done. The device immediately recognizes the player as a standard audio source. It is also possible to download a device manager to an actual computer, plug in the dragonfly and update to future software versions, but as of now, it is still version 1.0, so no updates are necessary/available - but it is good to know that if any efficiencies or features can be gained in the future through software update, the process is simple enough. Sound quality is a definitive improvement. Whether you listen to music through Apple Music, Spotify, Podcasts or rip your own, I can say that there is noticeable quality difference, regardless of of the bitrate quality of the rip. That said, I will not the key areas of improvement I observed. 1. Distribution of sound across the spectrum - this is the most immediately noticeable. I typically had to fiddle with the iPhone or iPad's internal equalizer to get the soundstage where I liked, but now, it's off completely. Sound distribution here is set well. I listen to a mix of genres but mostly R&B, Hip/Hop, EDM, Rock and top 40, and sound here would fit any of them well. Intricacies of that distribution will also depend on your headphones, but I can say the Dragonfly as the source is FAR better than the DAC inside Apple's devices. This is also one of the categories that is noticeable regardless of the headphones you are using. Even on a $30 pair, it's noticeably better. 2. Clarity/Separation of sound - this is also immediately noticeable but mileage will vary depending on your headphones and quality of the audio source. Even on a cheap pair of headphones, the sound will definitely be more crisp, but on a nice pair of headphones, the sound is more crisp AND you can truly hear separation amongst the sounds at different ends of the spectrum. Also, those subtle echos, bright spots and intricate sounds are simply more clear, hands down. I have the luxury of having a pair of headphones that can function as wired 3.5mm or wireless bluetooth, and comparing the difference in sound clarity between wired directly to iDevice, bluetooth and wired through Dragonfly is definitively noticeable. Bluetooth having the easily lowest rank amongst the three options. 3. Volume - This thing can push even a decent set of headphones pretty hard. Prior to the Dragonfly when plugging my headphones directly to the device, even at max volume, it was loud but tolerable and I could not get the headphone's drivers to distort at all. The dragonfly let's me up to about 80-90% volume (depending on the type of song) before it's too loud for comfort and at 100%, the headphone drivers are pushed too hard. They key is there is a much better sweet spot at high volume with no distortion that is sublime. In terms of potential downsides, there are a few things to be aware of but none that I would say should stop you from making the leap. First is battery life. The Dragonfly takes power from whatever device you've hooked it to, but another huge win here in that I have noticed no real difference. This could also be because previously I was using the iDevice's equalizer which also uses a bit more battery than not. In real world use, adding on the Dragonfly is a marginal, it all noticeable difference in battery life. Second is that as with any device plugged into the lightning port, you cannot charge the device and play through this at the same time unless you buy a separate adapter. And that adapter is UGLY and too large. I've still caved and bought the 2nd adapter that allows charging and playing and keep it on my desk for the rare occasion I need it but on the go use the regular usb/camera adapter. If you'd rather only have one and don't care about appearance, you can buy the larger adapter only, instead of buying both. Lastly, is that no in-line wire controls or functions are supported through the Dragonfly. This means, if your headphones have embedded volume, skip/previous, play/pause controls embedded in the wire, they will not function; also, microphone function will not work. So if you receive a call, you'll have to swap out the Dragonfly OR take the call with speaker or embedded mic in the iPhone. All in all, very happy with my purchase. One thing this has led me to hope for even more is that Apple adds higher bitrate streaming to the Apple Music service because once you get on this level, every little bit helps :)

No descubriré nada a los audiofilos con mi comentario. Seguro que habrá Dac USB mejores o que gusten más. Que tengan mejor relación calidad precio seguramente ya no. Para los usuarios normales que como yo dudan de hasta que punto merece la pena la compra de uno de estos: Produce una mejora significativa en la calidad de sonido con respecto a tarjetas de sonido integradas y/o sencillas. Esa diferencia puede ser abismal si lo comparamos con portátiles básicos o tarjetas de sonido usb económicas... y se reduce si comparamos con dispositivos que incorporan chips de sonido de calidad, como pueden ser tarjetas de sonido dedicadas decentes, placas base de gama alta o algunos mac. Por la diferencia de sonido... puede no merecer la pena la compra. Dependerá de las exigencias de cada uno, de con que lo comparemos, a que lo vamos a conectar, tipo de archivos que vamos a escuchar y de nuestro presupuesto. Obviamente, es tontería comprarlo si no es para combinarlo con unos altavoces o auriculares decentes. La mejora en sonido ya se nota si escuchamos archivos mp3, pero se vuelve más interesante para escuchar archivos sin perdida y sonido de alta definición. Yo reconozco que podría vivir sin él pero me lo he quedado. De hecho, compré también un Fiio K1, que cuesta la mitad, pero que sí he devuelto para quedarme con el Dragonfly.

Ancienne installation: ampli Rotel/CD Teac/enceinte Castle Trent II.... On remet un coup de jeune aux géniales Trent/Quobuz/Ampster BT II/ Nuc Intel sous Linux Mint et.... cette petite chose de Dragonfly. 600 euros, ramener en franc = 1/4 de mon ancienne installation. 1 Premier test sans le dac Wouha ... les enceintes respirent les aigus sont un peu trop présent mais humm de bonne basse précise et langoureuse. 2 Le Drangofly Plus de voie 😋... magique ... magnifique Tout est la, équilibre, finesse, espace , puissance. Mais le Drangofly reste en 16bit/44000. Pulse audio bloc ma sortie 😖 Avantage de Linux!!! on modifie les paramètres d’échantillonnage....Et le dac s’éclaire direct en violet. COOL 3 Le test ultime Purple Rain en 24bit/192. J’en pleure encore. Prince est ressuscité. 6 minutes de pure hypnose. 🙏 Alors les vieux, jeter votre vieux matos, et kiffer 😉le numérique. Et merci à Audioquest pour cette petite pépite.

I’m a satisfied owner of the dragonfly red and was a bit hesitant to buy the cobalt and not without a reason. Opinions online seem to be mixed. Some say that they can’t hear any difference. Some have done extensive technical analyses and trust their graphs more than their ears. Some prefer the red and insist that the cobalt brings a different flavour to music but isn’t necessarily an upgrade. Some disregard it without having heard it first simply due to the fact that it’s made by Audioquest – a company that sells cables for exorbitant prices, as well as other products of a questionable value, which may seem characteristic of a company that sells snake oil products. But I wanted to hear it for myself. If the sceptics were right, my plan was to return it. No loss. I kept it. On to the sound. Wow and meh. Okay, it absolutely sounds better and more fleshed-out than the red. They sound nothing alike. It certainly is tuned to sound differently. Whether you will appreciate the change, in my opinion, will not only depend on whether your headphones are resolving enough to reproduce the extra clarity and separation but also on how you listen to music. When listening to music while I’m answering e-mails or reading an online article, my ears don’t pick up much difference because my brain has to process so many other inputs. The story changes when I lay in my bed and enjoy music with my eyes closed. It’s then when this little thing takes me to another world. I pair the cobalt with Sennheiser HD650 and Beyerdynamic DT150. Both require quite a bit of juice to sound their best and the cobalt drives them sufficiently well, with a lot of headroom to spare. I rarely set the volume above 20 out of 100 for critical listening and usually it’s set on 8-12 on the windows volume slider for background listening. The first difference I noticed is the rolled-off treble and more impactful bass on the cobalt. It employs a minimum phase slow roll off digital filter that promises better impulse response and less artefacts that can muddy up the signal but the price to pay for this is a slight slope downwards in the upper treble region of the frequency response. For a casual listener, the red appears to be having more detail and sparkle in the treble region but the treble is a bit grainy upon more critical observation. The cobalt renders it fluidly and naturally. This quality will tame overly bright headphones and I noticed that the sibilance I experienced with the DT150 on some songs is no longer present. The cobalt goes louder without giving listening fatigue. The bass is another major improvement over the red. It is fuller and richer while being very tight (defined). Instruments and percussion instruments in particular carry more body and realism while on the red they were present and detailed but perhaps their identity was a bit lost in a mix. A drum hit now feels more authoritative. Lower registers of instruments can now be felt and feel less like a mere reproduction. The midrange is excellent on both but the cobalt enhances it by having better detail and separation of various elements in a mix. The red sounds a bit fuzzy in comparison as if the sound has been smeared a bit. Now, the difference isn’t big but it sort of puts you in the territory where artists come alive and stop sounding like a reproduction. One thing that stood out is the superior separation and imaging. Each instrument has a pin-sharp location on the soundstage. It was actually a jarring experience to listen to electronic music or tracks that contain many sound effects and elements that were baked in in audio software. Each element popped out vividly and some heavily edited tracks sounded fragmented. On multiple occasions my brain was imagining a cursor that was moving across the little squares that are placed on the timeline in audio software. Build quality. My unit seems to be rock solid and so far I haven’t experienced the issue of the board inside coming loose. I use my cobalt with the dragontail cable that was provided to minimise wear and tear on the USB plug and, by extension, on the board, as by doing so you don’t subject the board to forces when frequently plugging in and unplugging. I love it!

Una enorme mejora con respecto al (muy modesto) DAC que trae el iPhone incluido, no sólo en archivos 24 bits/96 kHz sino también con los mp3 de 320 kbps. Casi parece que estoy escuchando la música en una cadena de alta fidelidad, la señal es potente, con un sonido preciso y bien equilibrado en todas las frecuencias. Por cálculos creo que da para auriculares de hasta 50 ohmios, yo no iría más allá porque lo mismo nos quedamos flojos en cascos de 120 ohms o más: pero ya es una mejoría sustancial de la señal del móvil. Facilidad de uso total, enchufar con un adaptador USB A a la salida del móvil (lightning o la que sea), conectar auriculares jack 3,5mm y a escuchar! Se alimenta con la batería del móvil, no veo yo que sea muy devorador de culombios, pero hay adaptadores que permiten la carga simultáneamente (en apple al memos): yo cogí el lightning a USB A sin carga por ser más pequeño. En fin, una bendición para quienes somos sensibles a la alta calidad musical, vale cada euro que cuesta

My go to so far was a Helm Audio, which I much preferred over Ifi Hip DAC 2 despite bringing less depth and clarity to the sound, as it was warmer and more natural and pleasant. The Dragonfly Cobalt takes the best of the two. Depth in the sound, details, clarity, while remaining somewhat on the warmer side and providing a very natural sound. Love it! My new go to DAC for good sound on the go.
