Sena SF4 Bluetooth Communication System Double Pack

When you purchase your SF4, you will now receive two sets of speakers! 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.

For those who ride in small groups, the SF4 is equipped with 4-way intercom over 1.2 kilometers (0.8 miles). This model lets riders enjoy smartphone connectivity. Riders can listen to music and use the intercom simultaneously using the Audio Overlay feature. Please note that Audio Overlay works best with Android devices, while iOS offers limited functionality.
