7.8 USB DAC Mode
You can connect BP50 to your PC to work as an external USB stereo sound system using a USB

Some charging cable is only for battery charging and does not contain data link to transfer data.
You will need to select BP50 as the sound output device in your PC for it work. Look for the device name
call “Up2Stream USB Audio” and connect to it. Same as other input modes, you can stream your PC
audio to other connected Bluetooth device.
