FiiO QX13 Portable DAC &b Headphone Amplifier

The FiiO QX13 Portable DAC/AMP Combo is a compact yet high-performance audio device designed for audiophiles who seek hi-resolution sound, versatility, and portability. Built with a robust internal architecture and flagship-grade components, the QX13 delivers professional-level audio decoding that rivals desktop amplifiers — all in a pocket-sized form factor.

At its core, the QX13 features dual ES9027SPRO DAC chips combined with the XMOS XU316 USB controller, ensuring ultra-accurate decoding of audio formats up to 768kHz/32bit and DSD512. It also supports full MQA decoding, making it ideal for lossless streaming and critical listening.

The QX13 includes both 3.5mm single-ended and 4.4mm balanced outputs, powered by four TI INA1620 headphone amplifiers and two OPA1692 op-amps. This configuration provides ultra-low distortion, excellent dynamics, and crystal-clear sound — whether you’re using high-impedance headphones or sensitive IEMs. The device delivers powerful output suitable for both desktop and portable use.

Designed with user convenience in mind, the QX13 features a 1.99-inch IPS display, touch controls, and an intuitive interface. It supports the FiiO Control App (via Android and Web), allowing users to fine-tune parameters through parametric EQ and customize sound profiles. Thanks to UAC1.0 and UAC2.0 support, it’s fully compatible with PS5, Nintendo Switch, smartphones, and computers.

Encased in carbon fiber or aluminum alloy housing, with magnetic case accessories and broad cross-platform compatibility, the FiiO QX13 is the ultimate solution for achieving portable hi-fi performance anywhere.
