Receive voice commands, get GPS directions, listen to tunes, and take or make phone calls with ease without having to succumb to unnecessary distractions. When riding in groups, a rider can drop out of range and still come back to the conversation without doing anything. After a five-minute period, a one-button operation can allow reconnection to the group—it’s that easy to stay connected out on the highway. The M1-S system can easily adapt to any type of helmet with hard or soft mic options which are included in the package. Swapping the unit between helmets is also easy, via a quick attach/detach metal clip design. Bluetooth 4.1 connectivity.
