Throat Mic Picks Up Sounds Directly From Your Vocal Cords

Simply put, the Throat Mic "hugs your neck and picks up sound directly from your vocal cords; you can whisper and still be heard clearly on the other end and the person you're speaking to hears no outside sound."

Therefore a throat mic based headset is perfect to use in any noisy environment... like while laying down mortar rounds, or cruising in your convertible.
