SENA SF4 CONNECT AND COMMUNICATE IN SMALL GROUPS
SF4 is the perfect device for traveling with your small group of friends and always staying connected. SF4 has a range of 1.2 Km in open field so you can stay in constant contact with everyone. SF4 also connects to your smartphone, supports group music sharing, you can make and receive calls, and follow GPS directions. Moreover, thanks to the Audio Overlay ™ function, you can talk via intercom and listen to your music at the same time and with the Quick Charge you are ready to get on the saddle in a few minutes.
SENA SF4 IS AVAILABLE WITH HD EARPHONES
Each SF4 comes with a pair of standard earphones and a pair of HD earphones. While HD speakers promise superior audio quality and louder, clearer sound, standard speakers retain a smaller size and may be a more comfortable choice for some riders. SF4 is available in a standard package with a pair of earphones and in a double earphone package.
SENA SF4 STAY CONNECTED WITH THE SMARTPHONE APP
