What You Need to Know

Beautiful Sound from the Devices You Already Own

The AudioQuest DragonFly Copper is a pocket-size USB DAC, preamplifier, and headphone amplifier that bypasses the compromised audio circuitry in phones, tablets, and computers. Plug in your wired headphones and you’ll hear cleaner textures, greater dynamic expression, and a more natural sense of musical flow.

If you want a simple, portable upgrade that makes everyday digital listening more engaging, DragonFly Copper was designed for you.

More Power Brings Greater Control

A highly efficient 32-bit ESS Sabre DAC with an integrated headphone amplifier delivers twice the output power of any previous DragonFly. That added capability helps demanding musical passages sound more composed while giving a wider range of headphones convincing weight, grip, and scale.

A Copper-Plated Case Drains Away Noise

The high-conductivity copper-plated enclosure is more than a striking finish—it helps drain radio-frequency noise generated by nearby phones and computers. With less interference reaching the audio circuitry, low-level detail emerges from a quieter, cleaner background.

Less Battery Drain, More Listening Time

A smaller, more efficient processor reduces current draw by about 25% compared with previous DragonFly models. You get AudioQuest’s most powerful DragonFly while placing less demand on the battery in your phone, tablet, or laptop.

Low-Jitter USB Keeps Music in Time

Gordon Rankin’s StreamLength asynchronous USB code lets DragonFly control audio-data timing instead of relying on the source device. Together with monoClock technology, it reduces jitter and preserves the timing cues that make instruments sound focused, stable, and musically connected.

Made in America for Music Everywhere

DragonFly Copper’s circuit boards, assembly, and packing are handled by Mirac in Lynchburg, Ohio. Its USB-stick form, included DragonTail USB-C adapter, protective pouch, and driver-free operation make high-quality listening easy at home, at work, or on the road.

Building Your System

Connect DragonFly Copper directly to a computer through USB-A, or use the included DragonTail adapter with a compatible USB-C phone, tablet, or computer. Its 3.5mm analog output can drive wired headphones or feed powered speakers, a preamplifier, an integrated amplifier, or a receiver.

Copper works with Apple and Windows computers plus compatible iOS and Android devices that support USB audio. Apple devices with a Lightning connector require an Apple Camera Adapter, sold separately.
