The FiiO QX11 is a pocket USB DAC and headphone amp with dual ES9069Q DACs, a 3.5mm output and a 4.4mm balanced output rated up to 800mW + 800mW into 32Ω in Desktop Mode. It suits listeners who game and take calls on a phone or PC and also want a hi-res music DAC with a built-in mic.
Who the FiiO QX11 is for
Gamers and voice chat: Gaming Mode adds FPS, ACT, MOBA and MUG presets, and the built-in mic with AI noise reduction handles calls and team chat.
Headset users: The 3.5mm jack supports CTIA in-line mic headsets, and with the 4.4mm port the built-in mic can be used instead.
Hi-res music: HiFi Mode decodes PCM up to 32-bit/768kHz and native DSD512, with AUTO EQ and 10-band PEQ in the FiiO Control app or web interface.
Bigger headphones: Connecting power to the orange POWER IN port enables Desktop Mode, raising output to 800mW + 800mW balanced or 295mW + 295mW single-ended at 32Ω.
Long phone sessions: The POWER IN port passes up to 45W USB PD charging through to your phone or tablet while you listen.
Skip it if: you need Bluetooth or a built-in battery; the QX11 is a wired USB-C DAC/amp powered by the host or an external supply.
