LS2's 4X Intercom is a great way to keep in touch with riding buddies or the world in general, listening to music or keeping on track with satnav. Developed in collaboration with Cardo, it is a rugged unit, simple to operate and gives excellent sound.
Most of the current LS2 range of helmets will accommodate the 4X unit or you can choose one of the models that comes with it built in from the factory. All that you have to do is connect to your device and you are up and running.
