2-in-1 Bluetooth 5.0 adapter

This compact adapter adds Bluetooth 5.0 audio streaming to any device with a 3.5 mm jack. It works as both a transmitter and a receiver so you can send music from a phone to wired speakers or pull audio from a TV into wireless headphones.

Battery operation and low power draw

The unit runs from an internal rechargeable cell and draws minimal current during streaming. With no active cooling it stays silent, making it suitable for quiet rooms or overnight use in a car.

Hands-free calling and A2DP support

The bundled microphone enables clear hands-free calls when the adapter is in receiver mode. A2DP streaming ensures stereo music playback without extra drivers or software installation.
