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.
Sena 20S EVO Audio Multitasking™ technology allows you to have motorcycle helmet intercom conversation while simultaneously listening to music or GPS navigation. Forget the frustrations of interruption-based audio functions of past Bluetooth communication devices, the 20S EVO's audio features won’t interrupt each other, but simply overlay for a smooth listening experience.
The 20S EVO delivers HD-quality audio allowing riders to listen to music, GPS and make or take calls. Sena’s Advanced Noise Control™ helps so wind noise doesn’t interfere with incoming or outgoing audio, while the innovative Bluetooth® intercom for motorcycles allows you to talk with up to 7 other riders at distances up to 2 km (1.2 miles) away.
