FiiO QX11 Hi-Fi Slúchadlový zosilňovač Dark Green

Portable USB DAC and Headphone Amplifier with Gaming Sound Card

The FiiO QX11 is a compact, USB-powered DAC and headphone amplifier that doubles as a dedicated gaming sound card, bridging high-resolution music playback with competitive gaming audio. Two flagship ESS ES9069Q DAC chips handle decoding up to 768 kHz / 32-bit PCM and native DSD512, while a fully TI analog stage delivers low-noise, high-current drive. This dongle is the right choice for listeners who want desktop-grade amplification and a real gaming sound card in one portable device.

Dual DAC Architecture with TI Analog Stage and Patented Desktop Mode

Inside the dark green aluminum-alloy housing sits a SPV5068 USB controller feeding dual ES9069Q DACs based on ESS's fourth-generation 32-bit HyperStream architecture. 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 supports 45 W PD pass-through charging to the host device. The 1.14-inch IPS color display, single-button rotary control, and customizable multifunction shortcut button complete the user-facing hardware.

High-Resolution Decoding and DAC Architecture

The DAC stage pairs dual flagship chips with a high-resolution USB pipeline, and a separate digital output path lets the device act as a transport for an external decoder.

• DAC Chips: 2 × ESS ES9069Q — fourth-generation 32-bit HyperStream architecture for low-noise, high-dynamic-range conversion
• USB Decoding: 768 kHz / 32-bit PCM, native DSD512 — full high-resolution pipeline for studio-master and DSD music libraries
• USB Controller: SPV5068 — asynchronous transfer for low-jitter data delivery to the DACs
• Digital Output: S/PDIF via 3.5 mm jack, up to 384 kHz / 24-bit — turns the unit into a digital transport for an external DAC or active speakers

Headphone Amplification and Output Power

Output power determines which headphones a portable DAC can drive, and the QX11 scales from sensitive IEMs to full-size headphones via Desktop Mode. Both single-ended and balanced jacks are provided.

• Headphone Outputs: 3.5 mm single-ended + 4.4 mm balanced — covers both common portable cabling standards
• Op-Amp Stage: 2 × TI OPA1692 + 4 × TI OPA1622 in parallel — low-noise voltage gain feeding a high-current parallel headphone output

Connectivity, Power Delivery, and On-Device Control

Two USB-C ports separate data and power so the host device charges while audio plays. A 1.14-inch color screen and rotary control give tactile access to mode, gain, and EQ.

• Inputs: USB-C (data) + USB-C (power, up to 45 W PD) — listen and charge simultaneously
• Microphone: Built-in mic + 3.5 mm in-line headset support with AI ENC noise cancellation — clear voice for calls and team chat
• Signal-to-Noise Ratio: ≥126 dB (A-weighted) — quiet background for sensitive IEMs
• Display: 1.14-inch IPS, 135 × 240 — separate Hi-Fi and Gaming UI layouts with screen rotation

For Audiophiles, Mobile Gamers, and Hybrid Users

The QX11 is the right choice for listeners who want one device for both serious music listening and competitive gaming. Audiophiles benefit from dual flagship DACs, a fully TI analog stage, and 768 kHz / 32-bit plus native DSD512 decoding, with AUTO EQ via the FiiO Control app. Gamers get a dedicated Gaming Mode with FPS, ACT, MOBA, and rhythm-game profiles, a built-in microphone with AI ENC, and 3.5 mm headset support. Travelers appreciate the 36 g chassis, dual USB-C ports with 45 W PD pass-through, and Desktop Mode output when external power is connected.
