Sena SF4 Intercom System

The SF4 is the ideal device when you are out with friends, as it offers connectivity for small groups. The four-way intercom system of the SF4 has a range of over 1.2 km (0.8 miles), allowing you to easily stay in touch with your group in open terrain. The SF4 can also be paired with a smartphone to stream music, receive and make calls, and hear navigation instructions. And the best part: with the Audio Overlay™ feature, you can listen to music and use the intercom simultaneously. Additionally, the SF4 has a fast charging function, so you can be ready to go in no time.
