Selling points

 

Powerful performance

another step up

Inheriting the high-performance DNA of the KA17, the QX11 delivers further optimizations in sound quality, power efficiency, and user experience. As the newest member of the QX series, it represents both a continuation of proven excellence and a new starting point for portable HiFi.

 

Patented Desktop Mode Small size, Big power

Connect a power adapter or a portable power source such as the ESTICK to the dedicated power port to enable Desktop Mode, boosting output to up to 800mW + 800mW for effortless driving of your in-ear monitors and the vast majority of full-size headphones.

Patent number: ZL202321946664.8

 

Dual Type-C ports

Up to 45W PD charging

A dedicated power port supports up to 45W USB PD charging*, letting the QX11 charge your smartphone, portable player, tablet, or other compatible device while you enjoy your music—so you can listen longer without worrying about battery life. *Supports USB Power Delivery (PD) only. Actual charging power may vary depending on the connected device.

 

Dual flagship ESS ES9069Q DACs Silent background, Every nuance revealed

Powered by dual flagship ESS ES9069Q DACs based on the fourth-generation 32-bit HyperStream architecture, the QX11 delivers higher performance with greater power efficiency. Lower internal digital noise creates an exceptionally quiet background, allowing rich musicality and the finest details in every recording to emerge with clarity.

 

End-to-end TI audio architecture, Powerful and stable performance

The QX11 combines dual TI OPA1692 op-amps in the voltage gain stage with four parallel TI OPA1622 op-amps for headphone output, achieving ultra-low noise, ultra-low distortion, and outstanding driving power. The fully integrated Texas Instruments audio architecture brings out rich detail, expansive dynamics, and consistently stable performance.

 

Separate digital and analog boards

For crosstalk isolation

The QX11 features a design that separates the digital and analog boards and utilizes a shielding cover for isolation. This prevents mutual crosstalk and effectively ensures signal processing precision and dynamic range.

 

End-to-end independent powering, For clean, transparent sound

The QX11 employs a four-stage precision power supply design that filters out power ripple and noise stage by stage. Digital and analog circuits also use independently partitioned power supplies equipped with multiple high-precision, low-noise LDOs. The same power-supply layout used in professional headphone amplifiers delivers stable, abundant energy and provides a solid foundation for high sound quality.

 

AUTO EQ support Your ideal sound, One tap away

AUTO EQ is available on both the web platform and the FIIO app, automatically applying an EQ profile matched to your headphones for an optimized listening experience while maintaining accurate, uncompromised sound quality. The app includes multiple preset sound profiles, a 10-band adjustable PEQ, supporting up to PCM 384kHz/24bit. It is also optimized for FPS, ACT, MOBA, and MUG game scenarios, delivering vividly clear in-game sounds such as footsteps.

 

Dual-color aluminum alloy construction Premium looks, lightweight feel

The aluminum alloy body features a refined gradient finish with a distinctive pattern that highlights its premium appearance from every angle.

 

1.14-inch color display Landscape or portrait, Parameters at a glance

A larger display among dongles in its class, showing sample rate, gain, filter, and other professional parameters at a glance. Landscape and portrait UI themes are specially designed to match different usage habits.

 

Multifunction control knob

Every turn feels just right

The beautifully crafted volume knob features a double-sided 3D engraved design, making it an instant visual highlight. With smooth rotation, responsive press control, and outstanding tactile feedback, every interaction feels precise, intuitive, and satisfying.

 

A new shortcut button, Defined by you

The newly added physical multifunction shortcut button supports customizable single press, double press, and long press shortcut commands. You can customize it to match your usage habits, giving you one-touch access to your most frequently used functions.

 

Customizable options include: No action, EQ increase/decrease, mode switching, theme switching, screen rotation, and previous/next track.

​​​​​​​Default configuration: Single press→theme switching, double press→mode switching, and long press→next track.

 

Born for audio: Brand-new SPV5068 audio processor

The QX11 uses the high-performance RISC-V dual-core heterogeneous audio processor SPV5068, optimized for low-latency, high-compatibility, and energy-efficient USB audio transmission. With typical decoding power consumption as low as 150mW, it delivers a perfect balance of high performance and low power consumption.

 

Versatile features, For every scenario

 

Two modes, one seamless experience, HiFi & Gaming

 

Built-in microphone, with headset support Crystal-clear for calls and team voice chat

With a built-in microphone, support for 3.5mm in-line headsets, and AI ENC environmental noise cancellation, the QX11 keeps your voice clear whether you're on a call or coordinating with teammates in-game—so every conversation comes through loud and clear.

 

*When using the 4.4mm port, the QX11’s built-in microphone can be activated; desktop sound pickup is available in Gaming mode.
