2-in-1 Transmitter ReceiverThis unit functions as both a Bluetooth Transmitter and Receiver. In Transmitter mode, it connects non-Bluetooth audio sources to Bluetooth-enabled speakers and headphones using a 3.5 mm (AUX/RCA) cable. In Receiver mode, it receives audio from smartphones or other Bluetooth source devices, then transmits it via a 3.5 mm AUX cable to non-Bluetooth wired speakers, car or home audio systems. Treble/Bass Adjustment and Dual Device ConnectionThis audio adapter features a DSP chip for independent treble and bass adjustment. You can discover your preferred music experience by fine-tuning the sound effects.

It supports connecting two mobile phones simultaneously, but only plays audio from one device at a time. The ambient light can be switched off. Aluminum Alloy Shell and Broad CompatibilityThe housing is constructed from premium aluminum alloy, offering strength and durability. The Bluetooth adapter supports direct playback from USB storage devices. It is equipped with 3.5 mm AUX and RCA input/output interfaces, optical fiber, and coaxial input/output interfaces, and is compatible with most audio devices. It also features a 6.5 mm microphone interface, with built-in anti-feedback and intelligent noise reduction, enabling plug-and-play singing.

Note: Optical and coaxial ports function in transmitter mode. Extended Operating RangeThe Bluetooth adapter utilizes a dual-antenna design, achieving a line-of-sight range of up to 160 feet (50m) outdoors and 80-110 feet (25m-35m) indoors.
Note: The effective range may be reduced by physical obstacles such as Wi-Fi routers, wireless TV adapters, walls, metal barriers, etc., and also depends on the receiving device's capabilities
