  • Utilizing AKM’s new efficient AK4462 VELVET SOUND DAC and XMOS XUF208 USB chip allowing it to easily support decoding up to 768kHz/32bit PCM and DSD512, the Q3 achieves excellent performance.
  • With THX’s patented feed-forward error correction topology, the AAA amps have 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.
  • Multiple interfaces headphone jacks. The Q3 is equipped with 4.4mm/2.5mm balanced and 3.5mm single-ended outputs, allowing you to connect all kinds of headphones.
  • Modern USB Type-C input interface.USB-IF USB C compatibility certified: meets standard transmission interface specifications to ensure the compatibility of its USB solution
  • Thesycon official USB Audio driver: compliant with USB Audio 1.0 & 2.0 device class specifications. The Q3 can operate as a USB DAC when paired over USB with a computer. It can decode audio formats up to 384 kHz / 32-bit (PCM). No driver is needed for use with a Mac computer, while Windows will require a driver easily available from FiiO's website.
