i tried to search it on the web, all i can find is the price for it ( the whole kit with multiple speakers and head phones ). i want to know what exatly the speaker which you speak into is if anyone knows?
The kit you are looking into wont work for a mastercheif helmet. The MC helmet doesnt have airators at the bottom of the helmet. For MC, you're better off getting a cheap amp, or doing my idea and shoving the amp behind your chest piece.
