Bluetooth 5.0 3D Audio Adapter

Precision-engineered Bluetooth 5.0 stereo receiver, sized 6.5 × 4.2 × 1.8 cm and weighing just 42 g. Made from durable ABS plastic for long-term reliability. Powered exclusively via USB 5V/1A — no internal battery. Features native 3D audio mode activated via front-panel button, leveraging custom audio IC for real-time surround expansion. Supports TF/SD card playback (card not included). Includes full accessory set: 3.5mm aux cable, Type-C power cable, RCA stereo cable, and printed manual. Delivers lossless-quality stereo streaming to non-Bluetooth endpoints: car radios, powered monitors, Hi-Fi amplifiers, wired headphones, and home theatre receivers. Bluetooth 5.0 ensures faster initial pairing, lower power draw, and improved resistance to interference from Wi-Fi or other 2.4 GHz devices. Dual-device pairing allows persistent links to two Bluetooth transmitters — e.g. smartphone for music, smartwatch for notifications — with zero lag during source switching. Used widely in automotive retrofits, home audio modernisation, education settings (e.g. classroom speaker systems), and mobile DJ setups. Its compact footprint fits discreetly behind dashboards or inside entertainment cabinets, while its multi-port design avoids daisy-chaining or signal loss from third-party adapters.
