Sena SF4 Duo-Set Headset

The SF4 is the ideal device when you are out with friends, as it offers connectivity for small groups. The SF4's four-way intercom system has a range of over 1.2 km (0.8 miles), allowing you to stay in touch with your group easily 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’ll be ready to go in no time.
