High-End Components in a Tiny Package

Hats off to AudioQuest for not compromising and putting audiophile level components in the tiny DragonFly Cobalt package. A remarkable achievement!

Beautiful Sound from Any Mobile Device or Computer

Being able to enjoy music and videos on smartphones, tablets, and computers is now delightfully universal.

Unfortunately, the Digital-to-Analog Converters (DAC) inside these devices offer minimal performance, even when the sample-rate numbers (24/192, etc.) look impressive. Built-in DACs do the job but don’t give you nearly the clarity, dynamics, and sensuality that’s hiding in the digital file.

Whether using a free streaming service, premium HighResolution or MQA-encoded streaming (such as Tidal Masters) or playing your own MP3 files or videos — whatever you listen to or watch — all DragonFlys make the experience much more compelling and immersive.

And now DragonFly Cobalt, with its best-ever processor, headphone amp, and microcontroller, provides even greater clarity, dynamics, and finesse than previously possible.

Whether plugged into an Apple® or Windows® computer, or connected to an iOS® or Android® mobile device, DragonFly delivers beautiful sound to earbuds, headphones, desktop speakers, or complete audio systems, letting you hear all the emotional expression and nuance that makes your favorite music and movies so enjoyable.

Hint: For even more natural sound, put an AudioQuest JitterBug between your music and your DragonFly.
