Compact Bluetooth 5.0 3D Receiver

Ultra-compact Bluetooth 5.0 audio receiver measuring approx. 6.5 x 4.2 x 1.8 cm and weighing only 42 g. Delivers stereo audio through both 3.5mm aux and dual RCA (red/white) outputs. Requires continuous USB 5V/1A power supply — no internal battery. Features dedicated 3D audio mode activated by physical button, using proprietary chip-based upmixing for enhanced spatial imaging from standard stereo content. Supports TF/SD card playback (card not included). Housing made of impact-resistant ABS plastic. Includes 3.5mm audio cable, Type-C charging cable, RCA cable, and instruction manual. Engineered for compatibility with non-Bluetooth audio endpoints: connects seamlessly to car head units, desktop speakers, home amplifiers, powered headphones, and AV receivers. Bluetooth 5.0 ensures low-energy consumption, reduced dropouts, and stable performance within 10 m (33 ft) range. Dual-source support enables concurrent pairing — e.g. stream music from a phone while keeping a tablet ready for calls or voice assistant use. Typical use cases include retrofitting older vehicles with wireless audio, enabling wireless listening on studio monitors or Hi-Fi systems, supporting multi-user environments (e.g. shared office speaker), and providing standalone music playback via TF card in locations with limited smartphone access or signal coverage.
