Bluetooth 4.1 and Universal Intercom™ The Sena 10S Motorcycle Bluetooth® Communication System is an updated version of the original SMH10 model, which has proven itself as one of the best price/feature and quality ratio communication systems. The updated system has a lower profile and maximizes the enjoyment you get from communicating with crystal clear HD audio, with up to four fellow riders and a range of up to 1.6 km through the One Touch Group Intercom™ solution. The 10S also uses the Universal Intercom™ protocol, which means it can connect to both Sena and other Bluetooth communication devices on the market.
