FiiO QX11 – Desktop Power in Your Pocket

The FiiO QX11 is a pocket USB DAC and headphone amplifier built around two ESS ES9069Q chips and an all Texas Instruments output stage. Plug a power source into its second USB-C port and Desktop Mode lifts output to 800 mW per channel, enough for most full-size headphones. At Soundium it sits between dongle and desktop stack, for listeners who want one device for music and games.

Key Features

• Dual ES9069Q DACs: a very quiet background that lets low-level detail and decay come through cleanly.
• 800 mW + 800 mW Desktop Mode: add a charger or power bank and drive demanding full-size headphones with ease.
• Dual USB-C with 45 W PD: the dedicated power port can charge your phone or tablet while you listen.
• HiFi and Gaming Modes: FPS, ACT, MOBA and MUG presets bring footsteps and spatial cues forward.
• Built-in AI Noise-Reducing Mic: take voice chat and calls without a separate headset microphone.
• 1.14-Inch Colour Display: sample rate, volume, gain and EQ readable at a glance, in landscape or portrait.

Customer Benefits

Most dongles force a choice between small and powerful. The QX11 keeps the footprint of a pocket device (36 g, 64 × 28.8 × 13 mm) yet scales up when you are at a desk: one cable for the source, one for power, and suddenly planar and high-impedance headphones get real headroom. Separate digital and analogue boards and a four-stage power supply keep noise down, while the FIIO Control app adds a 10-band PEQ, AUTO EQ matched to your headphones and gaming presets. One box covers commuting, the desk and the gaming rig.
