AudioQuest DragonFly Cobalt Portable USB DAC Sweepstakes

Register to win an AudioQuest DragonFly Cobalt Portable USB DAC (Total value $299.95) we are giving away.

According to the company:

In 2012, the original AudioQuest DragonFly thoroughly disrupted the DAC market. For so many casual enthusiasts who had never previously considered the possibility of improving their digital-audio experience, DragonFly was nothing short of a revelation. Meanwhile, even the most experienced audiophiles were compelled to reexamine long-held notions of what a DAC could and should be. Stereophile's Art Dudley enthusiastically summarized, “DragonFly is fun: It's a thumb in the eye of those tea-pinky tyrants who would tell the rest of us what is and is not high end. I can think of no more recommendable product in digital audio.”


In the early months of 2015, AudioQuest surpassed its previous achievements with DragonFlys Black and Red—two sensational models that offered improved performance-to-cost ratios with unprecedented sound quality, free firmware updates, and, of course, the biggest news of all, compatibility with Apple® and Android® smartphones.

And now comes DragonFly Cobalt—AudioQuest's new flagship DAC. Cobalt takes what music lovers around the world have come to expect from the multi-award-winning DragonFly family—naturally beautiful, seductive sound—and strips away fuzz and fog that weren't even noticeable until Cobalt removed them.


How is this possible? Like the critically acclaimed DragonFly Red, Cobalt has the robust 2.1-volt output to drive almost any headphone, uses a bit-perfect digital volume control for outstanding signal-to-noise ratio, enables seamless compatibility with Apple and Android devices, and is an exceptionally competent and affordable MQA renderer.

Cobalt's precedent-setting performance is made possible by multiple significant upgrades:

  • New, more advanced ESS ES9038Q2M DAC chip with a minimum-phase slow roll-off filter for more natural sound.
  • Microchip's superb PIC32MX274 microprocessor draws less current and increases processing speed by 33%.
  • Improved power-supply filtering that specifically increases immunity to WiFi, Bluetooth, and cellular noise.
  • Includes AudioQuest's new DragonTail USB-A (female) to USB-C (male) adaptor to easily accommodate the increasing number of electronic devices that feature USB-C ports.
  • Contoured enclosure measures just 2.26” x 0.73” x 0.47” (57.5mm x 18.6mm x 11.9mm), making the latest DragonFly 10% smaller than its predecessors.

Like previous models, Cobalt uses Gordon Rankin's precedent-setting StreamLength® asynchronous-transfer USB code. Further, in Gordon's monoClock® technology, a single ultra-low-jitter clock generated from the ESS ES9038Q2M DAC chip runs the ESS chip functions as well as all microcontroller functions. This superior clock enables DragonFly Cobalt to provide greater resolution and clarity than DACs with multiple clocks.

With AudioQuest's DragonFly USB DAC, music appreciation and exploration are limitless: Plug into an Apple or Windows computer or connect to an iOS or Android mobile device. Play YouTube or Vimeo videos. Go hunting on Bandcamp or SoundCloud. Explore playlists on Spotify or Pandora. Stream high-res audio from Tidal or Qobuz. No matter the choice of musical pleasure, DragonFly delivers beautiful sound to earbuds, headphones, desktop speakers, or complete audio systems, unraveling the emotional expression and nuance that makes music and movies so enjoyable. Now, more than ever before, naturally beautiful sound is right at your fingertips—however you want it, whenever you want it.


The first 10,000 units of DragonFly Cobalt will come packaged with vouchers for trial subscriptions to the outstanding Tidal and Qobuz music-streaming services. Cobalt customers can begin their musical journeys with two new AudioQuest playlists—On an AudioQuest and Making Connections—available on Tidal and Qobuz, respectively.

I've been an AQ customer for over 25 years. Man that sounds like a long time when writing it! Most AQ purchases were interconnects, speaker cables and recordings. Would LOVE to get into AQ digital.

Yes Please

shagathlete's picture

Wow winning this would be amazing. I was recently looking at the red so this seems like fate.

eworkflow's picture

I'd love to comprehensively compare it with the Red...

RetiredinSD's picture

If I win a Cobalt I would compare to my Dragonfly Black to see if I could tell any difference between the two.

ixtlan07's picture

Hearing good things about this. Hoping I win.

I own the Dragonfly Red which is very good. Curious how good the cobalt is.

Bixby's picture

New stuff is fun.

bsher's picture

I've got an LG V40 and a Tidal subscription, and just installed USB Audio Player Pro, so this would be the final piece of the bit-perfect MQA puzzle!

Mike_Eastwood's picture

I've used the AudioQuest DragonFly Black for several years and it's been an amazing.

The quality – listening to Tidal or JRiver – when paired with my Sennheiser HD 380 PRO is exceptional.

And the cost per listen has been ridiculously low.

I can't wait to try the new Dragonfly Cobalt!

Holygeezer's picture

I just ordered a pair of Audioquest Nighthawk Carbon headphones and this would be a perfect match.

I purchased the original Dragonfly before the Black and the Red. I'd love to jump up to the Cobalt!

mpogorze's picture

I had a chance to hear a red one. I would love to hear the blue ( or cobalt )

bonifaxio's picture

I've wanted a Dragonfly since the original. Really exited about the Cobalt. Will finally give this a shot, especially now that I travel more. Just wish they'd gone with USB-C.

Waroroses's picture

This product elevates the bar for portable enjoyment. Now that I travel more, this will come in handy.

arksoundguy's picture

Waiting for my delivery. I don't know how long I can do this. If Bill Lowe is reading these He owes me for selecting his wire for our demo rooms at H.R. back in 1980.

labjr's picture

Cool little toy!

reuben_fuentes's picture

Wonderful. I almost bought a Red last weekend.

dalethorn's picture

Mine is in the mail (FedEx) already and should arrive end of the week. Expect a full review comparing to the DF Red, Explorer 2, Oppo HA2se, and more if I have time. I might even drag my JitterBugs out for a redo.

I have used the original dragonfly for years and love it. The Cobalt sounds like a great upgrade.'s picture

I have a red and would love to compare them back-to-back.
Thanks for the opportunity!

The new Audioquest DragonFly Cobalt DAC looks great! Would be so nice to win :-)

zulmer's picture

I've been reading about the AudioQuest DragonFly Dacs since they first arrived. Never got the money to buy one but would love to win this new one. The DragonFly would always get top reviews and I'm sure the Cobalt will follow suit.

IMWorks's picture

Used to see Red, but now I see Cobalt. On my radar for sure...

ianjwebster's picture

Love to try one

zaustin3's picture

Super DAC!!!!

HeadphoneDreams's picture

I have the black but would very much like this!

minoan's picture

Love hifi and Stereophile makes it better

otherwillsmith's picture

My Dragonfly Black has been a major quality of life upgrade for me. I travel a lot for work and this little device enables me to bring quality hifi with me. From listening to music on my iPhone in the Uber to watching movies on my iPad on the airplane, this little guy has changed how I feel about traveling for work. I have been using it on my computer at my desk lately and its improved the sound I get from my Audioengine speakers as well! I would love the opportunity to see what the Cobalt has to offer, as I can't imagine another device, in this form factor, competing with my Black. Thanks for the chance to win one!

coltrane1226's picture

Would love to win a Dragonfly of any color!

Hightop's picture

I use a DragonFly Red with an iPhone 8+ and headphones. I'll upgrade to the Cobalt (eventually). Thanks for the contest!

spyder1's picture

It is a beautiful designed portable USB DAC.

Mr Bones's picture

A few days ago, I was at my friend's house, listening to Tidal MQA through his DragonFly Black hooked to Nighthawk headphones. Impressive. So naturally, I would love to have the Cobalt.

TheoK's picture

Make my wish come true!

thelsuman's picture

Really love my DF Red. Can't wait to try the Cobalt!

Sadly, I’m not above begging the gods of randomness for this.
