AudioQuest DragonFly Copper USB Digital-to-Analog Converter
A USB DAC That Upgrades Sound From Nearly Any Device
The AudioQuest DragonFly Copper is a portable USB DAC, preamp, and headphone amplifier that plugs into a computer, phone, or tablet and takes over the job of converting digital audio to analog — bypassing the weak, noisy circuitry built into most devices. The result is cleaner textures, greater dynamic expression, and a more natural sense of musical flow, whether you're driving a pair of headphones directly or feeding a preamp, powered speakers, or a full audio system.
It plays everything from MP3s to hi-res streams from services like Tidal and Qobuz, with no drivers to install.
Built Around a 32-Bit ESS Sabre DAC
At the core of the DragonFly Copper is a 32-bit ESS Sabre ES9218 DAC with an integrated headphone amplifier, supporting native playback up to 24-bit/96kHz. AudioQuest's StreamLength asynchronous USB technology and monoClock circuitry work together to reduce jitter and preserve timing accuracy, so music arrives at the DAC with less digital noise to clean up.
More Power, Less Battery Drain
The DragonFly Copper outputs twice the power of earlier DragonFly models — up to 2.1V — giving it enough muscle to drive a wider range of headphones. At the same time, it draws 25% less current than previous versions, an important detail since it pulls power directly from whatever device it's plugged into.
A Copper Enclosure That Fights RF Noise
True to its name, the DragonFly Copper uses a high-conductivity copper-plated housing that helps drain away RF noise before it can interfere with the audio signal. A color-changing LED on the housing also doubles as a sample-rate indicator — red for standby, green for 44.1kHz, blue for 48kHz, yellow for 88.2kHz, and light blue for 96kHz.
Precise, Bit-Perfect Volume Control
Rather than relying on a device's own volume control, the DragonFly Copper handles volume in the digital domain with a 64-step, 64-bit bit-perfect control, preserving detail at any listening level. It supports both variable and fixed output modes, so it works equally well driving headphones directly or feeding a downstream preamp.
Plug-and-Play With Nearly Any Device
The DragonFly Copper connects over USB-A or USB-C, using the included DragonTail adapter, and works with Windows and Apple computers as well as iOS devices (with Apple's Lightning-to-USB Camera Adapter) and Android devices that support USB Host Mode. It's fully USB Audio Class compliant, so no additional drivers are ever needed.
Small Enough to Carry Everywhere
At just 12 x 19 x 57mm, the DragonFly Copper is barely larger than a USB flash drive, and it ships with a protective travel pouch so it can move between a laptop bag, a desk, and a pair of powered speakers without a second thought.
Is the DragonFly Copper Right for You?
- You want better sound from your laptop, phone, or tablet without replacing your whole setup.
- You listen mostly to standard and hi-res streaming or files up to 24-bit/96kHz.
- You want one small device that works with headphones directly or feeds a larger system.
- You want something compact enough to travel with and simple enough to need no drivers.
- You may want a dedicated headphone amp if you're driving high-impedance or planar headphones that need more power than a compact DAC can supply.
Frequently Asked Questions
What's the highest resolution it supports?
The DragonFly Copper natively plays up to 24-bit/96kHz. Higher-resolution files, such as 192kHz, should be downsampled to 96kHz for the best results.
Will it work with my phone?
Yes. iOS devices connect using Apple's Lightning-to-USB Camera Adapter, and Android devices work if they support USB Host Mode.
Can I use it with speakers instead of headphones?
Yes. Its 3.5mm analog output can drive headphones directly or feed a preamp, amplifier, or powered speakers.
Do I need to install drivers?
No. The DragonFly Copper is USB Audio Class compliant and works immediately on Windows, Apple, iOS, and supported Android devices.
What's included in the box?
Every DragonFly Copper ships with a DragonTail USB-C adapter, a protective travel pouch, a quick-start guide, and warranty documentation.
What warranty is included?
The DragonFly Copper carries a one-year parts-and-labor warranty from AudioQuest, plus Audio Advisor's 60-day money-back guarantee.
