Tech-Protect Ultraboost AU02 is a dual-function Bluetooth 5.4 audio adapter with a 3.5mm AUX output that functions as both a receiver (RX) and transmitter (TX) of audio signals. Thanks to the mode switch on the casing, one device replaces two - you can wirelessly receive audio from your phone on your hands-free kit or car speaker, but also send audio from your TV, computer or projector to your wireless headphones.
In RX (receiver) mode, the adapter connected to a speaker, car kit or receiver receives the audio signal from a phone or other Bluetooth device and plays it through the connected equipment. The built-in microphone enables hands-free voice calls directly through the car kit. In TX (transmitter) mode, the adapter connected to a TV or computer via the AUX socket transmits audio wirelessly to Bluetooth headphones or speakers - ideal for watching films or listening to music without cables.
Bluetooth 5.4 provides a stable connection at a range of up to 15 metres. The 180 mAh 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 approximately 2.5 hours. The lightweight and compact casing (just 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 equipment without a built-in module - in the car, home or office.
