dual ES9069Q DAC HIFI and Gaming DAC

The FIIO QX11 combines a high-resolution HiFi DAC and headphone amplifier with a dedicated gaming sound card in one compact device. Dual ESS ES9069Q DACs, a fully TI analog stage, HiFi and Game modes, AI microphone noise reduction, dual USB-C ports, 45W USB PD support, and up to 800mW + 800mW of balanced output in Desktop Mode make it equally suited to focused music listening and desktop or mobile gaming.

Breaking the boundaries between HiFi and gaming

Dedicated HiFi and Game modes give the QX11 two distinct operating environments. HiFi Mode draws on FIIO’s audio tuning expertise to preserve detail, dynamics, and tonal accuracy, while Game Mode uses purpose-built sound profiles and communication tools designed around competitive and casual gaming.

HiFi Mode
High-resolution decoding supports PCM up to 768kHz/32-bit and native DSD512, giving compatible recordings the bandwidth needed for detailed, true-to-source playback.

Game Mode
Game Mode adds AI microphone noise reduction and a streamlined interface with audio profiles tuned for different game genres.

Built-in microphone with headset support

A built-in microphone, support for 3.5mm in-line headsets, and AI ENC environmental noise cancellation help keep voice communication clear during calls and team chat. The integrated communication features make the QX11 practical for gaming without requiring a separate USB sound card.

Dual-color aluminum alloy construction

The aluminum alloy enclosure combines low weight with a refined gradient finish and distinctive surface pattern. At about 1.27 oz (36 g), the QX11 remains easy to carry while maintaining a substantial, precisely finished feel.

Dual USB-C ports with 45W PD support

A dedicated USB-C power port supports up to 45W USB Power Delivery, allowing the QX11 to provide power to a compatible smartphone, portable player, tablet, or other device while audio playback continues. Actual charging power depends on the connected device, and USB Power Delivery is required.

Patented Desktop Mode

Connecting a compatible power adapter or portable power source such as the FIIO ESTICK activates Desktop Mode, raising balanced output to at least 800mW + 800mW into 32Ω. The additional power expands compatibility beyond sensitive in-ear monitors to a wide range of full-size headphones. FIIO Desktop Mode patent number: ZL202321946664.8.

Dual flagship ESS ES9069Q DACs

Two ESS ES9069Q DACs use fourth-generation 32-bit HyperStream architecture to provide high decoding performance with improved power efficiency. Reduced internal digital noise contributes to a quiet background, helping low-level detail and fine spatial information remain distinct.

End-to-end TI audio architecture

Two TI OPA1692 op-amps handle voltage gain, followed by four TI OPA1622 op-amps operating in a parallel headphone-drive configuration. This fully TI analog architecture is engineered for low noise, low distortion, strong current delivery, and stable performance across a broad range of headphones.

1.14-inch color display

HiFi Mode
The dedicated HiFi interface displays key playback information including sampling rate, gain, and digital filter settings.

Game Mode
The gaming interface provides quick access to game audio profiles and microphone controls without burying commonly used functions in menus.

Custom-tuned game audio

Dedicated profiles are tuned for FPS, action, MOBA, and rhythm games. Each profile adjusts relevant in-game cues such as footsteps, skill effects, and gunshot positioning to make directional and timing information easier to identify during play.

AUTO EQ support

AUTO EQ is available through the web platform and FIIO app, applying an EQ profile matched to supported headphones. Presets for styles including Pop, Jazz, and Classical are also available, alongside a fully adjustable 10-band EQ for manual tuning. When PEQ is enabled, PCM playback is supported up to 384kHz/24-bit.

Multifunction control knob

The volume knob combines smooth rotation with press control and a double-sided 3D engraved design. FIIO rates both the press mechanism and rotary mechanism for more than 100,000 operations under laboratory testing. Actual durability may vary with operating conditions and use.

A customizable shortcut button

A dedicated multifunction button supports separate commands for a single press, double press, and long press. Available assignments include no action, EQ increase or decrease, mode switching, theme switching, screen rotation, and previous or next track. By default, a single press changes the theme, a double press changes mode, and a long press skips to the next track.

Versatile connectivity and controls

The 3.5mm connection supports S/PDIF output, allowing the QX11 to serve as a digital transport for an external DAC or compatible active speaker system. Compatibility with the FIIO ESTICK enables a compact powered desktop stack, and the QX11 can recharge the ESTICK when charging is enabled.

Adjustable volume precision

Selectable 60-step and 120-step volume control lets you choose between faster level changes and finer adjustment. The higher-resolution option is useful with sensitive earphones where small level changes can be more noticeable.

Extended control through FIIO Control

The FIIO Control app provides access to additional functions, configuration options, and both OTA and local firmware updates. FIIO Control support for the QX11 is currently limited to the Android version of the app.
