The SF4 is the perfect device for riding with friends by providing connectivity for small groups. The SF4's 4-way intercom has a range over 1.2 kilometers so you can easily stay connected with your group in open terrain. The SF4 also uses smartphone connectivity, allowing for music streaming, taking and making phone calls, and hearing.

Each SF4 comes with one standard and one HD speaker set. The HD speakers will take your ride to the next level with louder, clearer quality audio. The standard speakers are a bit smaller in size and may be a more comfortable choice for some riders. The SF4 is available in a standard package with 1 headset and a dual package with 2 headsets.
Link the Sena SF4 Bluetooth device to the Sena SF Utility App (available for iPhone and Android) to easily configure device settings and quickly access guides. The SF4 Bluetooth device also connects to the Sena RideConnected App, which allows for communication with a virtually limitless amount of riders over an infinite range, so long as you are connected to a mobile network.
