The Chatterbox Open Face Helmet Headset includes boom mike with foam sock, ear phones and attachment hardware. We offer only the open face style headset because it can be used in either open or closed face helmets. It offers superior performance to the full face helmet kit that ChatterBox offers on a wider range of motorcycles. If you use a full face helmet like most of do just pull your helmet on and move the mike up inside it so its right in front of your lips. The system is less suseptible to wind noise this way.
