User Tips
1) This is a USB audio transmitter used to Bluetooth-enable your PC/PS4/Nintendo Switch. It cannot be used for
TVs or car stereo systems to stream music from your mobile phone/tablet.
2) This will not work for transferring data from/to your mobile phone from your PC. Peripherals which also work
by transferring data will not work - products such as Bluetooth keyboard / mouse, game controllers, printers,
projectors and other BLE (Bluetooth Low Energy) devices.
3) To get better operational range, please don’t hang leaf behind the computer. We suggest using Avantree
headphones to get the best Bluetooth stability and range. An unclean USB port can result in a crackly/static-like
sound. Carefully clean the port, either using a nylon anti-static ESD brushes, or changing to another cleaner
port should x the problem.
