special comm system for helmets???

hey gang,
i while back i remember reading a post on here(i think) about a comm system that could be put into fett/tk helmets that only picked up voice waves, eliminating background noise so you acn even whipsper adn it will transmit crystal clear. Can anyone help me out with what that product is called? i know it has fox somewhere in the name. Any help in proving that i didnt dream about reading this would be great, thanks guys in advance:?:?

You thinking of the Firefox Throat Mic?
