It has two profiles available, the Headset Profile and the Hands-free profile.

With advanced noise control and wide volume control, the SENA 20S EVO dual pack allows the rider to stay sharp as well as be in contact with all the fellow riders.

Headset Profile

The Headset Profile defines a simple audio connection between a Bluetooth audio gateway, like a cell phone, and a headset. The profile also supports a single button to start or end a call, and the use of a volume control.

Hands-Free Profile

The Hands-Free Profile is much more robust than the headset profile. You can switch between calls on your phone’s call waiting systems, dial numbers, access your phone’s address book and handle three-way calls.

Hands-free devices can even read off caller ID numbers, control your phone’s echo cancellation and noise reduction functions, and use voice control.
