TWO MAIN FUNCTIONS: The Bluetooth receiver has the conventional Bluetooth receiver function and the Bluetooth Broadcast function (Broadcast TX), supports Bluetooth one to many, and can transmit the sound of one device to multiple different devices via Bluetooth (the receiving end needs to support the Broadcast receive function or LE sound).

2. REGULAR RECEIVING FUNCTION: With this Bluetooth sound adapter, you can easily wirelessly transfer sound from any Bluetoose enabled device, including smartphones, tablets, computers, and laptops, to any stereo system or speaker. The Bluetooth receiver provides Bluetooth functionality for existing stereo, active speakers, car stereo, home stereo, or 3.5mm wired headphone
