RevZilla carries a variety of motorcycle helmet intercoms and entertainment devices, most of which are using Bluetooth technology. Technology has moved very rapidly and today's bike-to-bike communication systems are affordably priced and work very well. Range and specific details vary between the units, but most of the available kits are universal, working with any full face, open face, and even half helmet through either clamp-on systems or adhesive. Some Motorcycle Helmets come with provisions for Bluetooth kits to reside completely inside the helmet. Many of these units will also offer the ability to play MP3, sync to GPS, via their bluetooth speakers and even sync to your phone. If you have any specific questions about the functionality or differences between the units, do not hesitate to give us a call or email.
