Next-gen Bluetooth 5.4 transmitter for high-resolution audio

A next-generation HD Bluetooth audio transmitter built for modern systems and legacy sources alike, the xDuoo MX-02 converts wired high-resolution audio into stable, low-latency wireless output. Powered by a Qualcomm Bluetooth 5.4 chip, it supports LE Audio, aptX Lossless, and a wide range of codecs for uncompromised sound quality. With USB, Optical, Coaxial, and Line inputs, it turns nearly any source—TV, CD player, or console—into a high-fidelity Bluetooth broadcaster.

From wired to wireless—without compromise

Many devices still lack high-quality Bluetooth transmission. Even when built-in, the Bluetooth stack often limits format support or introduces signal instability. The MX-02 bypasses these shortcomings. Its multiple input options—USB, Optical, Coaxial, and Line—feed into a robust digital conversion stage capable of up to 24-bit / 192kHz input. The result is a lossless wireless signal path that maintains the clarity and precision of a wired connection.

High-resolution conversion and codec flexibility

The MX-02’s digital inputs handle true high-resolution audio, accepting up to 24-bit / 192kHz PCM from coaxial or optical sources and 24-bit / 96kHz from USB. On the output side, it supports a full codec suite including aptX Lossless, aptX HD, aptX Adaptive, and LDAC. This ensures compatibility with everything from studio-grade headphones to portable Bluetooth receivers, letting users prioritize either low latency or absolute fidelity as needed.

Bluetooth 5.4 and LE Audio

At the heart of the MX-02 is Qualcomm’s Bluetooth 5.4 chip—engineered for stronger, cleaner, and more efficient wireless transmission. It extends range, lowers power consumption, and minimizes interference. Support for LE Audio and its LC3 codec brings latency down to as low as 20ms—ideal for real-time applications like gaming and video playback where synchronization is critical.

Designed for everyday systems

Plug-and-play functionality makes the MX-02 instantly compatible with computers, PlayStation 5, and Nintendo Switch via USB input. Automatic power-on, adjustable screen brightness, and auto screen-off functions streamline operation. The aluminum alloy enclosure adds both durability and electromagnetic shielding, maintaining stable signal integrity over long-term use.
