Tech-Protect Ultraboost AU02 Bluetooth 5.4 Audio Adapter - Black

The Tech-Protect Ultraboost AU02 is a dual-function Bluetooth 5.4 audio adapter with a 3.5mm AUX output that acts as both a receiver (RX) and a transmitter (TX) of the audio signal. 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.
