Sena Expand Boom Bluetooth Communication System

The waterproof headset is specially designed for outdoor activities - for a secure hold in any situation. With the Expand Boom you can talk headset-to-headset, make phone calls or listen to music at any time. No matter which circumstance - enjoy the crystal-clear sound of Sena.

Safe from water and sweat, you can always rely on your headset. The Expand Boom is the only Bluetooth headset of its kind with water resistance.

Bluetooth 3.0 technology enables four-way communication over a range of 900 meters. Advanced Noise Control™ ensures that loud environmental noise doesn't interfere, and each audio source has its own volume level that can be adjusted to your preference. Integrated voice announcements further assist with setup and operation.

Even if your friends don't use a Sena, you can still connect and communicate with Bluetooth devices via a Univesal Intercom™.
