FiiO QX11 — Portable USB DAC & Headphone Amplifier
The FiiO QX11 is a compact high-performance USB DAC and headphone amplifier that combines flagship-level dual DAC architecture with a powerful all-Texas-Instruments amplification stage. Designed for both high-fidelity music playback and competitive gaming, the QX11 delivers desktop-class audio performance in a pocket-sized form factor.
Dual Flagship ES9069Q DACs
Built around two ESS ES9069Q flagship dual-channel DAC chips, the QX11 supports true high-resolution audio processing with 32-bit/768kHz PCM and native DSD512 decoding. The dual-DAC configuration ensures exceptional channel separation, ultra-low distortion, and rich detail retrieval across the entire frequency spectrum.
Powerful All-TI Amplification
The analog stage features an end-to-end Texas Instruments architecture: 2× OPA1692 for pre-amplification and 4× OPA1622 in parallel for headphone driving. Delivers up to 800mW + 800mW balanced output in Desktop Mode, with enough power to drive demanding full-size headphones. The 4.4mm balanced and 3.5mm single-ended outputs cover all headphone types.
Dual Mode: HiFi & Gaming
Switch between dedicated HiFi Mode for pure, uncolored music playback and Gaming Mode with genre-specific sound profiles optimized for FPS, ACT, MOBA, and rhythm games. The gaming mode enhances spatial awareness, footsteps, and directional cues for competitive play.
