The New B1 Twin system is an entry-level BlueTooth communication kit, which includes both the headset and the BlueTooth unit in one easy-to-install system for two helmets. 
It is optimized for one rider or for a couple riding on one motorcycle, as the distance for helmet to helmet communication is limited to 150ft.

• Rider to passenger communication via BlueTooth.
• Other devices can be connected to the B1: Music players and other devices using a standard headphone jack can be connected via a MultiMedia Wire (not included) and other BlueTooth-enabled devices such as a cell-phone and a GPS can be paired through the BlueTooth connection. 
• Firmware updates can be done by connecting the B1 to a computer via the USB cable (included) with the NCom Wizard program.

 Please note:

There is no cord currently to plug your B1 into a Harley Davidson or Honda Goldwing to utilize the bikes radio or CB.
