Intercom SENA SF4 Dual Pack. The SF4 is the perfect device for riding with friends, providing connectivity for small groups. The SF4's 4-way intercom has a range of over 1.2 kilometers (0.80 miles), so you can easily stay connected with your group in open terrain.

The SF4 also connects to your smartphone and allows you to play music, receive and make calls, and hear turn-by-turn GPS directions. Most importantly, riders can listen to music and use the intercom at the same time with the Audio Overlay™ feature. Plus, the SF4 has a quick-charge feature, so you'll be ready to hit the road in no time.

Each SF4 comes with a pair of standard headphones and a pair of HD headphones. While the HD speakers promise superior sound quality and louder, clearer sound, the standard speakers are smaller and may be a more comfortable option for some riders.
