I have a pair of Z-Tactical Comtacs and I love them so far. Well, until this issue came up. I can still receive audio from other radios. I've even checked my PTT and tried using other headsets with it, and the PTT comes out OK. So this leaves the mic or some wiring issues inside the comtacs to blame. I was wondering if anyone has had this problem or knows what to do? I Don't know where to start on taking apart the headset, nor do I know if I need to since a replacement mic is fairly cheap. Any help would be GREATLY appretiated!!
