Sena 20S EVO-11D Motorcycle Bluetooth Headset Communication System with HD Speakers, Dual Pack

The 20S EVO was designed with a fixed type, shark fin antenna as opposed to the flip up antenna of the original 20S. This sleek antenna design improved group Bluetooth intercom stability and distance, while updates to the hardware allow for a more robust general performance. In addition to its original updated design, the latest upgrade for the 20S EVO are Sena's premium HD speakers.
