A good DAC should disappear into the setup, not demanding any attention or taking over a desk. The high-resolution amplifier should be better at doing just one task – simply making your headphones or earphones sound better. FiiO’s new QX11 takes that idea in a more ambitious direction, packing the kind of amplification and audio processing normally associated with larger desktop equipment into a compact USB-C device that can travel with your modern-day gadgets.

The Chi-Fi brand’s latest offering is designed for listeners who want more than a basic headphone dongle. Beneath its compact aluminium alloy and forged carbon-fiber body are two flagship ESS ES9069Q DAC chips, paired with four Texas Instruments operational amplifiers. The configuration supports PCM playback up to 32-bit/768kHz and native DSD512, giving it plenty of capability for high-resolution music without turning the device into an unnecessarily bulky piece of hardware.

The biggest upgrade from FiiO KA17 is arguably the amount of power available to headphones. In Desktop Mode, the QX11 can deliver up to 800mW + 800mW, exceeding the 650mW + 650mW output of the predecessor. That extra headroom is particularly useful for demanding headphones and high-impedance models that can benefit from stronger amplification and better control. FiiO also wants the QX11 to work beyond traditional music listening. A dedicated Gaming Mode introduces audio profiles for FPS, ACT, and MOBA games, allowing the same device to shift from a high-resolution music DAC to a more gaming-focused audio interface.

Voice communication is also built in, as QX11 features a microphone and AI environmental noise cancellation intended to suppress surrounding sounds during voice chats. For someone using wired headphones, that means fewer accessories are needed to create a more complete gaming setup. The audio gadget also brings a more accessible approach to equalization with FiiO’s software ecosystem, as users can select supported headphone models and apply automatic correction profiles instead of manually adjusting individual frequency bands. Genre-specific EQ presets further allow the sound to be tailored to different types of music.

There is also a thoughtful solution to one of the less glamorous problems with powerful portable DACs: battery drain. The QX11 incorporates dual USB-C ports with 45W USB Power Delivery passthrough, allowing a connected phone or laptop to receive power while the DAC is being used. This makes it more practical for longer listening sessions or gaming away from a conventional desktop setup.

With green and gold finishes, Fiio QX11 has enough visual character to stand out without looking like conventional gaming hardware. At $170, the DAC is tailored for buyers who care as much about versatility as raw specifications. Rather than being another dongle focused solely on decoding high-resolution files, QX11 is a compact audio hub capable of moving between serious music listening, gaming, and everyday portable use without changing the rest of the setup. Indeed, something for a starter audiophile like me who likes things less complicated.
