Your fingers will instantly know

Lots of connectors for lots of 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 having 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.

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.

No regrets for its powerful decoding abilities
