Sena 20S Evo interphone bluetooth double

20S EVO is a state-of-the-art Bluetooth communication system for motorcycles and powersports. The unit offers an elegant and aerodynamic design, which offers a versatile jog dial that maximizes the ease of use for pilots.
An absolute novelty is the introduction of Bluetooth 4.1 technology with dual communication module, to create one of the most advanced Bluetooth headsets on the market. The new Bluetooth technology increases the performance and reliability of the headset while also allowing more high-definition audio quality. Advanced Multitasking audio allows a perfect combination of incoming and outgoing audio.
With the 20S, users can call hands-free with their Bluetooth cell phones, listen to music or voice instructions of Bluetooth GPS navigation wirelessly, and have full-duplex intercom conversations with a passenger or other drivers.
The Sena Smartphone App is available for iPhone and Android to allow users to adjust their 20s settings.
The 20s has an updated softwer, and a more robust antenna that is less prone to breakage than the previous model.
