Supports up to 768k/32Bit and native DSD512, easily decoding Hi-Res music.

3 mainstream headphone outputs

2.5mm/3.5mm/4.4mm jacks, covering all of your needs.

Analog potentiometer volume knob

Quickly adjust volume with great accuracy, not having to worry about channel imbalance.

RGB sampling rate indicator

Easily distinguish between sampling rates with yellow, green and blue lights.

Multiple certifications

Multiple certifications from USB-IF, THX, Thesycon, Hi-Res Audio.

Always brilliant

1800mAh battery means battery life of 10 hours or more under USB decoding.

Certified to be talented

The Q3 has obtained multiple certifications as a testament to its reliability and to its variety of talents.

*Apple certified, fully compatible with iOS devices

*USB-IF USB C compatibility certified: meets standard transmission interface specifications to ensure the compatibility of its USB solution.

*THX AAA™ amp: for a guaranteed natural and realistic listening experience.

THX AAA amplifier technology pure, natural sound

With THX’s patented feed-forward error correction topology, the AAA amps have a low distortion, high power and a pure, uncolored sound. You’ll experience subtle details and shocking swings in your music effortlessly with the AAA amp in the Q3.

Humbly powerful on the inside all-new DAC AK4462

Utilizing AKM’s new efficient AK4462 VELVET SOUND DAC with decoding support up to 768kHz/32Bit PCM and DSD512, the Q3 achieves excellent performance.

No regrets for its powerful decoding abilities

The Q3 comes with the same XMOS XUF208 USB chip as found on FiiO’s flagship DAC/amplifier, allowing it to easily support decoding up to 768khz/32Bit PCM and DSD512.

Classic design with a pleasing roundness

The Q3 is continuation of the design language of FiiO’s other amplifiers-its elegant curves, simple lines, smooth CNC and sandblasted all-aluminum body give it sturdy yet beautiful look while remaining practical to use.

Lots of connectors for lots fun

The Q3 is equipped with 4.4mm/2.5mm balanced and 3.5mm single-ended outputs, allowing you to connect all kinds of headphones. You don’t have to sacrifice compatibility with single-ended headphones while have fun with the balanced output!

*Output priority is: 4.4 balanced=2.5 balanced>3.5 SE. If 4.4 and 2.5 balanced are connected at the same time, there is no output.

Light up the moment

The RGB indicator on the volume knob allows you to easily distinguish between different sampling rates, and spices up your listening experience!

*≤48k Blue

*>48k Yellow

*DSD green

More lows with the same highs

A bass switch allows you instantly activate/deactivate the bass boost function. The purely hardware-based bass amplifier circuit can increase bass by up to 6dB without affecting the mids or treble.

Versatile multi-function

To make the Q3 more convenient to use, a multi-function button allows you to quickly switch between gain levels and filters. Change your sound with some simple taps!

*Short press the button to switch between low/high gain. Light on for high gain, light off for low gain.

*Double-tap to cycle between sharp and slow roll-off filters.

Your fingers will instantly know

Among professional audio products, nothing adjusts volume better than an analog potentiometer volume knob. When combined with DAC curve reconstruction, traditional problems with analog volume knobs like low-volume channel imbalance are effectively eliminated-so that you can quickly and accurately change to your desired volume.

Highly capable decoder, better component arrangement

Dual crystal oscillators

Independent LPF circuit

Low noise volume adjustment

Still ready even after a long day

Despite its high-performance components, the Q3 has long battery life. The 1800mAh battery means 10 hours or more music under USB decoding, definitely enough for a normal day of listening.

Interference shielding for purer sound quality

High-strength all-aluminum body + copper-nickel shield + highly efficient absorbers form a 360°radio frequency interference shield around the Q3. Even when using it right next to a smartphone, one would be hard-pressed to detect any interference.

Instantly connect with the symmetrical type-c connector

The type-c connector on the Q3 allows you to connect it to more devices, and allow for more convenient charging with support for USB PD and Lightning charging.

Always unfazed

The Q3 is a powerful decoder always available to unlock your music wherever you go.

Use with a Lightning to type-c converter for iOS devices.

Use a dual type-c head cable to connect to Android devices and control the Q3 with the FiiO music app.

Can be use with Sony Walkman players with an adapter cable.
