The K3 is a full-face motorcycle helmet with a Bluetooth 5.0 headset built into the shell. It pairs with a phone for music, automatic call answering and FM radio, so there is no separate communicator to mount or charge. It also has a quick-release buckle meant to work with gloves and a double lens with a drop-down sun visor. Riders who want one integrated unit instead of a helmet plus an add-on headset are the target; the trade-off is that the electronics are fixed to the helmet and cannot move to another one.
