The Sena SPH10 is a versatile, portable outdoor Bluetooth headset and intercom. It is extremely easy to operate using the multifunctional dial and offers a range of up to 900 meters for up to 4 participants. The outdoor Bluetooth headset and intercom from Sena stands out particularly due to its unique operation with the jog dial. This hemispherical push-and-turn knob makes it easy to use even with thick gloves.

Both hands remain free while communication is ensured.
