The Invisio Bone Mic cell phone headset allows users to communicate via cell phone even in high-noise environments. The headset fits totally into one ear. Because the mic only receives vibrations from the user’s jaw bone, the mic signal is not adversely affected by high ambient noise. The headset works with cell phones that have “echo cancellation” and is supplied with a 2.5mm jack. Universal or custom earmolds are available.
