Mic not working how do I find out if it's the Mic boom
Have a pair of the turtle beach elite pro my Mic stopped working I can still hear everything fine. But the mic won't work on my Xbox or phone how do I find out the problem. I.e is it the Mic boom or faulty wire because I don't want to buy a new Mic boom if mine is fine
