Sena’s SF4 Connects Riders On The Road

Designed for riding with up to three friends, the SF4 from Sena is devised to easily integrate intercom and smartphone services into your helmet. The four-way intercom connects riders up to 0.8 mile away from each other, letting the whole group of four talk to each other while out on the road. Bluetooth connectivity lets you listen to your music or pick up calls, as well as getting turn-by-turn directions from your in-phone maps.

A new Audio Overlay feature lets riders talk on intercom without pausing their music, lowering the volume of the music whenever a connected rider starts to speak. The SF4 unit also pops off of your helmet, allowing easy charging and not requiring you to plug your whole helmet in like you have to on Sena’s other low-profile unit, the 10R. This SF unit it also equipped with quick charging capabilities, ensuring it’s ready to go when you are.

Compared to the SF1, SF2, or SFR, the SF4 is not too much more expensive and offers you the option to connect with more riders, so we would recommend making the price jump now, rather than regretting it when you can’t talk to your friends later.
