V5.3 TX RX Stereo Bluetooth Adapter

A precision-engineered Bluetooth 5.3 adapter combining transmitter and receiver functions in one palm-sized unit. Size: ~6.5 × 4.2 × 1.8 cm; weight: 42 g. Powered exclusively via USB-C (5V DC). Offers 3.5mm AUX input (for receiving audio), 3.5mm AUX output (for transmitting), and USB-C (power + Bluetooth handshake). Supports SBC, AAC, LDAC, and aptX LL codecs. Tested range: up to 30 m in open space. Enclosure: matte black ABS with tactile port identification. Package contains 1x USB-C cable (1 m), 1x 3.5mm stereo cable (1.2 m), and quick-start guide. As a transmitter, enables lossless-grade stereo streaming from non-Bluetooth sources to two Bluetooth endpoints — e.g., share laptop audio with partner’s headphones while keeping yours connected. As a receiver, accepts audio from two phones — useful for monitoring personal and business lines, or switching between music libraries without disconnecting/reconnecting. Prioritises audio authenticity: low-jitter clocking, shielded internal traces, and direct DAC-path routing ensure minimal colouration. Firmware tuned for rapid connection recovery and adaptive packet scheduling — maintains continuity during brief obstructions (e.g., walking past router or microwave) without audible glitches or rebuffering.
