FiiO QX11 Hi-Fi Headphone Preamp Gold

FiiO QX11 Gold — Dual-Mode HiFi and Gaming DAC Amplifier

The FiiO QX11 Gold is a portable USB DAC and headphone amplifier that bridges audiophile-grade listening and competitive gaming in one compact device. Two flagship ESS ES9069Q DAC chips sit at the heart of the signal path, paired with a fully TI analog stage and switchable HiFi and Game operating modes. The QX11 Gold is the right choice for listeners who want desktop-class power, mobile convenience, and gaming-grade features without carrying two separate devices.

What makes the FiiO QX11 Gold unique in its category

Most portable DAC/amps focus on music playback alone. The QX11 Gold adds a dedicated Game mode with FPS, action, MOBA, and rhythm-game profiles, plus a built-in microphone with AI ENC environmental noise cancellation and 3.5 mm in-line headset support. A Desktop Mode unlocks up to 800 mW + 800 mW balanced output when an external USB-C power source is connected, while a second USB-C port delivers 45 W PD reverse charging to keep a phone or portable player topped up during play.

DAC architecture and decoding — high-resolution signal chain

The DAC stage is the part of any portable audio chain that decides how faithfully digital music is converted into the analog signal your headphones receive. Two flagship ES9069Q chips running fourth-generation 32-bit HyperStream architecture handle decoding, while a fully TI analog stage — two OPA1692 op-amps for voltage gain and four OPA1622 op-amps in parallel for headphone drive — keeps the output clean and controlled.

• DAC Configuration: 2 x ESS ES9069Q — dual-mono flagship decoding for a quieter noise floor and improved channel separation
• PCM Decoding: 768 kHz / 32-bit — full support for studio-grade and high-resolution music files
• DSD Decoding: Native DSD512 — bit-perfect playback of DSD recordings without downsampling
• USB Chip: SPV5068 — driver-free USB input for plug-and-play use with phones, tablets, and computers

Amplification and outputs — desktop power in a pocket-sized body

Power output determines how well a DAC/amp can control a pair of headphones, especially planar-magnetic or high-impedance models that demand current. The QX11 Gold's Desktop Mode raises balanced output to up to 800 mW + 800 mW. Both 3.5 mm single-ended and 4.4 mm balanced headphone jacks are present, and the 3.5 mm port doubles as a coaxial S/PDIF output for feeding an external DAC.

• Headphone Outputs: 3.5 mm single-ended, 4.4 mm balanced — covers both common cable terminations
• Coaxial S/PDIF Output: Up to 384 kHz / 24-bit — turns the QX11 into a digital transport for an external DAC

Connectivity, controls, and gaming features — built for daily use

The QX11 Gold is designed to be the only audio device a listener carries between a desktop setup and a mobile gaming session. Dual USB-C ports separate data and power, a 1.14-inch color LCD shows sampling rate, gain, volume, and mode at a glance, and a customizable shortcut button plus a multifunction knob handle playback, EQ, and mode switching without reaching for the FiiO Control app.

• Inputs: USB-C (data and power) — driver-free plug-and-play with phones, tablets, laptops, and consoles
• USB Power Delivery: Up to 45 W reverse charging — keeps the source device powered during long listening or gaming sessions
• Built-in Microphone: AI ENC noise cancellation — clear voice pickup for calls and team chat, with 3.5 mm in-line headset support
• Display: 1.14-inch color LCD — shows sampling rate, gain, volume, mode, and EQ status
• Game Audio Profiles: FPS, action, MOBA, rhythm — tuned presets that surface footsteps, skill effects, and positional cues

Who the FiiO QX11 Gold is for

The FiiO QX11 Gold is the right choice for listeners who split their time between critical music sessions and competitive or casual gaming and want one device that handles both without compromise. Audiophiles driving full-size headphones benefit from Desktop Mode's 800 mW + 800 mW balanced output, while mobile users get a quiet, detailed signal for sensitive in-ear monitors. Competitive gamers gain a low-latency Game mode with genre-specific profiles and a built-in microphone with AI noise cancellation, and content creators or remote workers can rely on the same microphone for clear voice calls. The FiiO Control app adds parametric EQ, AUTO EQ headphone matching, and OTA firmware updates, making the QX11 Gold a flexible daily driver rather than a single-purpose dongle.

FiiO — bridging HiFi and gaming in one chassis

FiiO built the QX11 Gold to break past the conventional boundaries between portable DAC/amps and dedicated gaming sound cards. The brand name itself combines Fi (fidelity from HiFi) and iO (the digits 1 and 0), reflecting FiiO's focus on digital audio innovation at accessible prices. By combining dual flagship ES9069Q DACs, a fully TI analog stage, dual USB-C ports with 45 W PD support, and a Desktop Mode in a 36 g aluminum enclosure, FiiO delivers a single device that covers focused music listening, mobile gaming, and desktop headphone driving.
