Super-premium sound, everywhere

You might think awesome sound quality is hard to achieve on the go. If so, we'd like to present the handy AudioQuest DragonFly Cobalt USB DAC/headphone amp. It's roughly the size of a thumb drive, and it plugs into your phone or computer to deliver premium, high-precision sound. AudioQuest's highly successful DragonFly models put the USB DAC category on the map, and the Cobalt looks to be the best one yet. It makes for an easy and very effective upgrade to your portable or desktop listening setup. 

I have a sample of the Cobalt coming my way, but I'm already very familiar with the DragonFly Red and DragonFly Black v1.5. I actually own the latter, and often use it to audition the latest and greatest headphones. It slips right into my laptop bag, and its sound rivals that of some popular (non-portable) desktop DACs out there. So I'm beyond excited to try the Cobalt, which should sound even better.  

AudioQuest's fastest, best-sounding DragonFly

AudioQuest loaded the Cobalt with a brand new high-performance USB microcontroller that increases processing speed by 33% (over the DragonFly Red and Black). Faster processing means less extra noise, and ultimately less distortion. 

This chip also reduces power consumption. That's important if you're listening on the go, because the DragonFly draws its power from your connected mobile device or computer. So you can enjoy the upgraded sound without sucking your phone or laptop's battery dry. 

A better internal DAC

AudioQuest also replaced the DAC found in previous DragonFly models with an improved 32-bit ESS Sabre ES9038Q2M processor. This high-performance DAC chip features slow minimum-phase filtering for AudioQuest's most nuanced, dynamic sound yet. And it is one reason why this compact DAC/amp can perform at the level of much larger components.

The DragonFly Cobalt also features the same headphone amp as the DragonFly Red, which I've found gives even hard-to-drive headphones plenty of volume and punch. (I've even driven some super-sized, power-hungry planar magnetic over-ears with that built-in amp.)  And the 64-bit digital volume control offers super-precise sound level adjustment with no loss of detail.

Enjoy high-res USB audio

The DragonFly Cobalt is designed make everything you listen to sound better. So even the compressed audio you get from MP3s, Spotify®, Apple Music®, or YouTube videos will get a sonic boost. But if you have a high-resolution music collection, or stream lossless music from Qobuz or TIDAL, you can really hear what the Cobalt can do.

This DAC will decode high-resolution music files up to 24-bit/96kHz resolution, which is better than CD quality, and it also offers full MQA support. There's little to no fuss as you switch from one file type to the next or one music service to another. The dragonfly-shaped logo on the DAC's exterior even lights up and changes color to verify the resolution of the incoming signal.

AudioQuest DragonFly Cobalt connected to iPhone

The DragonFly Cobalt connects to your iPhone via a Lightning-to-USB connector (sold separately).

For headphones or speakers

Plug your headphones directly into the DragonFly's stereo 3.5mm mini audio output jack for high-energy private listening. You can also use an optional stereo mini-to-mini cable or mini-to-RCA adapter to feed a line-level signal to a pair of powered speakers, power amplifier, or receiver. 

Compatible with most phones and computers

The DragonFly Cobalt can plug directly into the USB port on a computer, but there are several ways to connect to other devices. AudioQuest includes a DragonTail USB-C adapter that will connect to the USB-C port on a newer computer, phone, or tablet.

For Apple devices, AudioQuest recommends using the Lightning-to-USB 3 Camera Adapter. We also offer a DragonTail micro USB adapter and a DragonTail USB extender separately. All of these flexible adapters offer a little slack, so it doesn't put much strain on your device's port.

Almost like wearing a headphone in my helmet

Crutchfield customer from Jasper, IN on 8/11/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a fantastic piece of kit. It was purchased as one of the component piece to drive a pair of Tesla speakers for my motorcycle helmet. I can say that the Cobalt really brought those speakers to life and I am now able to enjoy a musical concert feeling in my helmet on the highway at 70 mph

Pros: Aside from musicality the small light weight design makes it effortless to carry

Cons: I've not noticed any negative as of yet

Review of the new AudioQuest DragonFly Cobalt USB DAC.

Crutchfield customer from Jackson, KY on 8/8/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I use the new AudioQuest DragonFly Cobalt USB DAC in my 2014 Dodge Challenger SXT+. I connect the Cobalt's 3.5mm audio output port to the 3.5mm input port of my Pioneer Supertuner 3D+ using a high quality 6ft long 3.5mm unbalanced coaxial cable with 2 male stereo 3.5mm plugs on each end. I use the included DragonTail USB-A to USB-C adapter to connect my 1 TB iPad Pro 3rd generation to the input USB-A plug on the Cobalt DAC. I use Tidal Hi Fi on my iPad Pro and play MQA Master Files that I have pre-downloaded to the 1TB solid state hard drive of the iPad Pro. The cobalt has multi colored LED that shows the sample rate of the audio track being played. The Cobalt is the cheap way out to play great sounding MQA Master music files through your vehicles head unit. I highly recommend the Cobalt! It sounds excellent in the vehicle and will power all headphones too!

Pros: Cheap way to add MQA capability to your vehicle's head unit. Also plays Apple Music downloads. It's small. Great to play MQA through your headphones too.

Cons: None

Disappointing

Alex from East Tawas on 8/4/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Man am I sorry to be writing this, but I jumped the gun and ordered the Cobalt as soon as it became available... largely because I like the Red version so much. BUT, my unit may be defective as it emits a constant, very high pitched noise when in use. AudioQuest worked with me for too long trying to troubleshoot the issue, but have stopped short of calling it defective. I immediately decided to swap back to the Red model (I had given away my original Red). Crutchfield chat was great about setting up the swap. I wish it had been the product that it has been hyped to be, and MAYBE a firmware update will eventually help, but for now I'll be fine going back to the excellent Red model. YMMV!

Pros: Sounded good, perhaps only a wee bit better than the Red; something rattles slightly inside the unit.

Cons: Constant audible noise in the background (approx. 2kHz).

Small but significant upgrade

Crutchfield customer from Santa Barbara, CA on 8/2/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Have had the DragonFly Red for a while. Use it with iPhone X and Flacbox and on MacBook Pro with PureMusic. For headphones on the go, I use in-ear monitor Etymotics ER4XR. Compared the Red and the Cobalt and notice the more open sound of the Cobalt with somewhat tighter/cleaner bass. Both set to 88.2 kHz. in PureMusic I always have to select 88.2 kHz when switching to Red, while with Cobalt it automatically uses the higher sampling frequency, which is nice. Tracks listened to are dark/cold wave by PublicMemory, Zanias, Boy Harsher and Austra. Then also with alternative singer songwriter (Cat Power: Cross Bones Style), which gives a slightly more nuanced voice. Also tried some baroque strings and voice (Ariosti: Pur al Fin Viola Thomas Georgi and Emma Kirkby). For on the go, a great solution for very good audio. Will be interesting to see whether the Cobalt is a little bit gentler on iPhone battery (no data yet). The difference between Red and Cobalt are not as profound as between iPhone/MacBook built-in DAC and either of the Dragonflies. If improvement from built-in to Red = 100 then then Red to Cobalt is around 25. For home use, my Woo WA6SE tube headphone amp with Grado Reference 2 open headphones still has the edge on natural sound.

Pros: Audioquality,

Cons: none.

Major Problems - buggy. Avoid

Crutchfield customer from Norfolk, VA on 7/29/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was REALLY excited about this new version of the Dragonfly. I originally started with the Black and then upgraded to the Red several years ago. The Red was amazing and worked on everything all the time. The Cobalt apparently has a bug in it's volume control (among other bugs). The sound (when it works) is not noticeably better than the Red. I'm returning mine and going back to the Red - at least I will have a $100 back in my pocket. Avoid this product until Audioquest does something major to fix it.

Pros: It's pretty

Cons: Pretty much everything: buggy, marginal improvement over Red (when it works), and expensive.

Crutchfield response on 8/1/2019
We appreciate the review. Our headphone writer Jeff says: "I've been using the DragonFly Cobalt for a few weeks, and haven't run into problems with the volume control. We'll contact the customer to get some specifics about his setup and the problems he's having, then run those by AudioQuest to see what we can find out."

Cobalt FTW

Crutchfield customer from Lubbock, TX on 7/28/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Great sounding little DAC. It really improves the quality of the music when listening on my phone. The difference is night and day. The build quality though is just mediocre. The USB/board/headphone jack all move around inside the little plastic case and makes a rattle noise when moved around. As far as I can tell it doesn't effect how the little device works. Only time will tell how it holds up. I'd still recommend this device to anyone who wants to enjoy great sounding music while on the go.

Pros: Music quality Sounds great

Cons:

Sounds amazing. Another step above the red in a compact dac to use with your phone, computer, or car. Was hoping for an update like this with a sabre 9038 dac, and here we have it. Others charge thousands for their devices with this chip. What a deal. Audioquest has hit it out of the park again.

AudioQuest DragonFly Cobalt

Crutchfield customer from Long Beach, CA on 7/22/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

As with my DragonFly Red, the new Cobalt adds huge improvements to my IEMs. I did have the usb "wiggle" issue with my unit, but the amazing customer service at Crutchfield will be taking them back and replacing them with a perfect non-wiggling unit. My past fantastic experience with AudioQuest products and now with Crutchfield's flawless customer service, add up to my 5-star review.

Pros: Tiny, beautiful design/color, amazing performance. A little pocket rocket!

Cons: The "wiggling" issue of the usb piece.

Cobalt > Red + Jitterbug

I had been using a Red with a Jitterbug in series. Sound improvement with the Cobalt is palpable (I am not using the Jitterbug any longer). Crisper, more vibrant. Not to mention in a smaller, sleeker package. Highly recommended.

More details on the AudioQuest DragonFly® Cobalt

Mark G.

Product Research

Features

Overview: The AudioQuest DragonFly Cobalt is the new flagship model in the DragonFly series of compact USB DACs. The DragonFly is the size of a typical USB flash drive, and has an advanced digital-to-analog chip, and a high quality headphone amplifier. Its USB Type A input simply plugs into your desktop or laptop computer (Windows or Mac), or, with an adapter, into your Apple or Android smartphone or tablet. On the other end is a 3.5mm minijack output for your headphones, powered speakers, or your home's stereo system. The DragonFly Cobalt bypasses the inferior quality sound card in your device to deliver beautiful, clean audio to your ears. The package includes a 6" DragonTail, a female USB-A to male USB-C adapter, and a stitched leatherette storage pouch.

Digital-to-Analog Converter: The DragonFly Cobalt has a new, more advanced 32-bit ESS Sabre 9038 DAC chip (ES9038Q2M). Natively, the DragonFly Cobalt is capable of decoding 24-bit/96kHz data. Files with higher sample rates will need to be resampled to a compatible resolution. The DAC has a minimum-phase slow roll-off filter which delivers a natural, warm sound with great detail. DragonFly Cobalt is designed to play any file type, no matter the resolution, from your smartphone, tablet, or computer. This includes CD audio, MP3 and AAC compressed music files, CDs ripped as Apple Lossless or FLAC files, plus streaming audio from free or premium services such as Tidal, Qobuz, or Spotify.

Note: DragonFly is an MQA renderer only, and must be used with the appropriate software to unfold the MQA files.

Headphone Amplifier: Like the DragonFly Red, the DragonFly Cobalt uses the ESS Sabre 9601 headphone amplifier with a high-level output of 2.1V @ 10k ohms or higher. It will drive a wide range of headphones, including inefficient, power-hungry models. Its 64-bit, bit-perfect digital volume control provides excellent signal-to-noise ratio, a wide dynamic range, and high fidelity. When DragonFly Cobalt is connected to your computer or mobile device, the source unit's volume control will perfectly adjust the DragonFly's volume.

Microcontroller: DragonFly Cobalt uses an efficient Microchip PIC32MX274 USB microcontroller that draws less current, and increases processing speed by 33%. Wavelength Audio's monoClock technology, with a single ultra-low-jitter clock to run the headphone amplifier and all of the microcontroller functions. StreamLength (also from Wavelength Audio) asynchronous USB code improves the delivery of the audio samples to the DAC chip to give you reliable connectivity between the DAC and the host device for uncompromised audio playback.

Noise Filtering: The DragonFly Cobalt utilizes improved power-supply filtering to eliminate the effects of noise from cellular, Bluetooth, and Wi-Fi signals in the air.

Compatibility: The AudioQuest DragonFly Cobalt is compatible with a wide range of devices, from desktops and laptops, to smartphone, tablets, and digital music players:

  • Apple iOS: DragonFly Cobalt is compatible with Lightning Connector-equipped Apple iOS devices. (It is not compatible with 30-pin Apple devices). In order to connect the DragonFly to your iOS device is to use Apple's Lightning to USB 3 camera adapter (sold separately). You should use the included DragonTail USB-C to USB-A adapter, if connecting the DragonFly Cobalt to the latest iPad Pro.
  • Android: It is compatible with most Android devices running Jelly Bean OS (4.1 or newer). To connect the Android device, you'll need to use the included DragonTail (with USB-C) or the optional DragonTail with microUSB (sold separately). If the DragonFly Cobalt seems to have too little output, you will need to purchase and download the USB Audio Player PRO app (currently $7.99 US), which includes its own USB audio driver. This application is compatible with various audio formats and will manage music on both the Android's internal memory and inserted microSD cards. Additionally, with your Android phone connected to a WiFi network, this app can find and connect to DLNA servers/libraries. USB Audio Player Pro Version 5 supports audio from Google Music, Tidal (including Tidal Masters), Qobuz, and Shoutcast, and includes an MQA Core Decoder.
  • Windows: DragonFly Cobalt is compatible with Windows PC (Windows 7 through 10). No additional drivers are required for DragonFly Cobalt to operate with Windows PC.
  • Apple OS X: It is compatible with Mac computers (OS X 10.6.8 or later). No additional drivers are required to operate with Mac OS X. To connect to Macbook or Macbook Pro, which are equipped with USB-C ports, you should use the enclosed DragonTail Adapter (with USB-C).

LED Indicator: The LED indicator behind the DragonFly icon shows the resolution of the incoming signal - 44.1kHz (green), 48kHz (blue), 88.2kHz (yellow), 96kHz (light blue), and MQA (purple). Red indicates standby mode.

Software Upgradable: The DragonFly Cobalt is upgradeable through a free Desktop Device Manager application. As new developments arise in music player applications, streaming protocols, or other associated software, you can upgrade your DragonFly Cobalt to incorporate those updates to your device.

Q
Can I still use the jitterbug with the cobalt or do I not need to now?
[ Ed  Jul 20, 2019 ]
3 answers
A
From what I understand, you don't need to use a jitterbug because the Cobalt already has electronic filters built in.
[ Reza  Jul 20, 2019 ]
A
AQ recommends only using the Jitterbug in parallel with the Cobalt, not in series.
[ George  Jul 20, 2019 ]
A
If I understand correctly, the Cobalt has a Jitterbug-like front end built-in to clean up power/noise. Seems like the Jitterbug would still be useful for the Dragonfly Black and Red but perhaps not as beneficial for the Cobalt. That said, can you use it? Sure. In the end, it's up to you to determine whether it's actually sounds better with or without the Jitterbug.
