Sena SF4 – Product Overview & Specifications

Overview

Each SF4 comes with one standard and one HD speaker set. The HD speakers deliver louder, clearer audio for an enhanced riding experience. The standard speakers are slightly smaller and may be more comfortable for some riders. The SF4 is available as a single headset package or as a dual package with two headsets.

Link the Sena SF4 Bluetooth device to the Sena SF Utility App (available for iPhone and Android) to easily configure device settings and access guides. The SF4 also connects to the Sena RideConnected App, enabling communication with a virtually limitless number of riders over an infinite range, as long as a mobile network is available.
