This lightweight in-helmet communications system mounts without tools to the helmet liner using a unique strap fastener system. The ear speaker provides ambient sound and allows the user to hear incoming radio communications without blocking their ability to hear what is going on around them. Voice transmissions are picked up by a noise-resistant microphone which sense sound vibrations and voice audio directly from vibrations in the user's skull, making it very resistant to picking up background noise.

Easily and quickly installs into most hardhats or helmets with plastic liners. Note that due to the nature of the bone conduction technology, transmit audio may have a different fidelity than a normal microphone which picks up sound that travels through the air. However, voice transmissions should be completely understandable.

Bone Conduction Microphone - The diaphragm of the microphone rests against the user’s skull when the microphone is installed and the helmet is worn. The microphone picks up voice audio directly from vibrations under the user’s skin. The SPM-1700 Series is the In-Helmet Skull Microphone to have.  This one mounts without tools to the helmet liner. Get your today and priced right.
