3D Stereo Bluetooth 5.0 Adapter

Lightweight (42 g) and space-saving Bluetooth audio adapter (6.5 × 4.2 × 1.8 cm), built with robust ABS casing. Operates on external USB 5V/1A power only — no rechargeable battery. Equipped with Bluetooth 5.0 chipset for extended 10-metre range, rapid reconnection, and stable stereo transmission. Offers three physical audio outputs: 3.5mm aux jack, left RCA, and right RCA — all active simultaneously. Includes dedicated 3D audio toggle button and multi-function key (MFB) for track/volume control. Supports TF/SD card playback (card not supplied). Package includes receiver unit, 3.5mm cable, Type-C cable, RCA cable, and quick-start guide. Designed specifically to add Bluetooth functionality to legacy audio gear: connects to car stereos lacking Bluetooth, passive bookshelf speakers with aux input, home theatre pre-outs, or headphone distribution systems. The dual Bluetooth pairing feature supports true multi-tasking — e.g. stream Spotify from phone while receiving WhatsApp voice notes from tablet. Internal circuitry handles lossless-format decoding and real-time 3D upmixing without latency or compression artifacts. Common deployment scenarios include transforming a basic car audio system into a wireless-ready hub, enabling hands-free music sharing in small offices or studios, providing portable audio flexibility for DJs or educators using wired speaker arrays, and serving as a backup audio player during travel using locally stored TF card content.
