The unit comes complete with 240v Mains USB adapter plug and charging lead. A clamp type helmet fixings included for your convenience.
Which Devices does it “Pair” with?
The unit will pair to 4 other headsets of the same model and many other makes as a single pairing, as well as most modern mobile & smart phones. Garmin & TomTom sat-navs. It can play from music devices by Bluetooth. It even has a built-in fm radio receiver!
