Has ambient noise canceling, wind blocking ability of the high-output AeroMike® III microphone, along with the superior audio performance offered by wide-fidelity helmet speakers. This headset can be connected to any factory installed motorcycle audio system, now and in the foreseeable future, just by interchanging the lower-section hook-up cord. Single.
