FiiO QX11 Compact Headphone Amplifier

The FiiO QX11 is a compact USB DAC and headphone amplifier designed for both high-resolution music listening and immersive gaming audio. Built to go beyond the limits of a traditional portable “dongle” DAC, the QX11 combines serious Hi-Fi hardware with dedicated gaming features, giving you one device for music, calls, voice chat and competitive play.

In Hi-Fi mode, the QX11 supports high-resolution playback up to 768kHz / 32-bit PCM and native DSD256, powered by dual ESS ES9069Q DAC chips. This gives the QX11 a clean, detailed and dynamic sound with a low-noise background, whether you are listening from a phone, tablet, computer or portable player.

For gaming, the QX11 includes a dedicated game mode with specially tuned sound effects for different game types, including FPS, action, MOBA and music games. These sound modes are designed to help improve immersion and make key audio cues such as footsteps, effects and directional sounds easier to pick out.

The QX11 also includes built-in microphone support, making it practical for voice calls, online chat and gaming communication. It has an internal microphone and also supports compatible 3.5mm inline microphones, helped by dual-channel audio return and environmental noise reduction.

With both 3.5mm single-ended and 4.4mm balanced headphone outputs, the QX11 works with a wide range of earphones and headphones. In desktop mode, using the independent power input, it can deliver up to 780mW + 780mW of balanced output power, giving this compact amplifier enough drive for many demanding headphones.

The dual Type-C design also supports independent power input and up to 45W PD charging, allowing you to listen while powering connected devices such as phones, players or tablets. A 1.14-inch IPS colour screen, physical shortcut button and finely machined volume wheel make everyday control simple and responsive.

Finished in aluminium alloy or forged carbon fibre body options, the FiiO QX11 is a powerful compact audio upgrade for listeners who want serious Hi-Fi sound, gaming audio features and flexible headphone support in one portable device.
