Transmitter and Receiver Audio Adapter

This 2-in-1 Bluetooth 5.0 adapter adds wireless audio to devices with a 3.5mm aux port. It operates as a transmitter to send sound from a TV or PC to headphones, or as a receiver to stream music from a phone to wired speakers. Power comes from a USB 2.0 connection. The compact black unit suits home and portable setups.

Who It Suits and Who It Does Not

Buyers who want a single device to both send and receive Bluetooth audio will find this useful. It is not for users who need aptX low-latency codec support or multipoint pairing with two headphones at once. It also does not suit installations that require an optical digital audio input or output.

Bluetooth 5.0 Wireless Standard

The adapter uses Bluetooth 5.0 for a stable wireless link with compatible headphones, speakers or car stereos. Range and connection quality depend on the environment and the paired device. Version 5.0 offers improved speed and range over older standards. Check that your source or sink device supports Bluetooth 5.0 or earlier for correct operation.
