This ingenious device provides Bluetooth® audio streaming on Hi-Fi and other audio playback devices without native Bluetooth®. The receiver recharges using the included USB recharge dock, then plugs into your 3.5mm audio socket. Then you simply pair your streaming device to the dongle and it’s as if you connected a 3.5mm audio cable (but there’s nothing to trip over!). The dongle itself includes playback controls, as well as a microphone, meaning you can use it as a full function hands-free device if you are paired with a smartphone. When it’s running low on battery, simply pop it back into the USB charger and connect to a USB port to charge.
