Invisio caters to police officers, first responders, security teams, and military personnel who use 2-way radios in noisy conditions. Ear piece lets user maintain clear conversation, even when whispering, plus receives incoming radio messages. Unlike traditional microphones worn in front of ones mouth or on a lapel, the device picks up vibration of jaw bone, rather than ambient speech and noise. Comes in 2 styles: standard model fits right ear of any user; custom model is made from imprint of users left or right ear to ensure comfortable wearing for up to 20 hrs. Each model links with interfaces for connection to any 2-way radio.
