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. Designed with a beveled taper, the HD speakers fit easily into helmet pockets and give riders a more comfortable experience. Sena’s HD speakers offer a marked increase in volume, bass boost, and clarity.
