Tech-Protect Ultraboost AU02 Bluetooth 5.4 Audio Adapter - Black

With a mode switch on the case, one device replaces two - you can wirelessly receive audio from your phone on a hands-free system or car speaker, but also stream audio from your tv, computer or projector to wireless headphones.In rx (receiver) mode, an adapter connected to a speaker, car kit, or receiver receives an audio signal from a phone or other Bluetooth device and plays it back through the connected hardware. The built-in microphone allows you to make hands-free voice calls directly through the car kit.

In tx (transmitter) mode, an adapter connected to a tv or computer via the aux jack transmits audio wirelessly to Bluetooth headphones or speakers - ideal for watching movies or listening to music without cables.Bluetooth 5.4 provides a stable connection within a range of up to 15 meters.

The 180mAh battery lasts for 5 hours of music playback or calls, and the standby mode lasts for 100 hours. Charging via the usb-c port takes about 2.5 hours.

The lightweight and compact housing (only 12 g) does not interfere with everyday use.The Tech-protect Ultraboost au02 is a simple and effective solution for anyone who wants to add Bluetooth connectivity to their equipment without a built-in module - in the car, home or office.
