Q11 Portable DAC and Headphone Amplifier

Listening to true HiFi on a phone
Not a problem

Are you feeling anxious under the condition that more and more phones lose the headphone jack, more and more streaming services offer lossless audio, and dongles are hungry for power supply? Every issue will be perfectly solved with the Q11. It offers no compromises thanks to its high performance and longer battery life (for itself and your phone), providing you with a HiFi music experience.

Truly-moving sound
Thanks to internal magic

The Q11 is truly "Born For Music" thanks to the carefully-selected components integrated into a well-thought-out design, all in a meticulously-tuned package.

With form and function
Superb sound and shape

The compact body of the Q11 is specifically designed so that the Q11 can be bundled together and used with the vast majority of phones. The straight and smooth edges of the Q11 make it a joy to use in the hands, while the elegant black finish combined with the gold label accents makes the Q11 an eye-catching device.

Powerful portable
Sound with personality

With a balanced power output of up to 650mW, as well as low and high gain levels, it is easy to listen to both low and high-impedance headphones on the Q11 anytime, anywhere.

Great parts and great sound
Have it all

Thanks to the high-performance CS43198 DAC, dual op-amps, high-precision crystals and low-noise power supply, the Q11 is highly resolving and dynamic for a more immersive listening experience.

PCM: 384kHz/32bit; DSD256

Long battery life
For a true piece of mind

Whether it's on the work commute or weekend travels, you can be sure that you will be able to listen to the Q11 all day thanks to its large battery.

Battery capacity: 2600mAh; Battery life＞13h

Ambient light window
Your ticket to the HiFi world

The ambient light window not only dazzles you with lights that indicate the current sampling rate or DSD format, but also allows you to elegantly peer at the internals currently giving you your music.

Light blue: PCM sampling rate 48kHz or below
Yellow: PCM sampling rate above 48kHz
Green: DSD

*The Q11 can be controlled by the FiiO Control app, with settings of ambient light on/off, filter selections, etc.

Common outputs
For the everyday listener

The 3.5mm SE and 4.4mm balanced outputs are clearly outlined by a golden ring, allowing for more versatility and better sound quality for music on the go.

*The 3.5mm headphone output also supports coaxial output.

Two-in-one knob
An elegant fusion

The silky and perfectly weighted feel of the volume knob allows you to precisely dial in your desired volume. It also conveniently acts as an on/off switch.
