I got a Bluetrek X2 bluetooth headset. I'm trying to play on-line for the first time. I'm Playing Resistance FOM. When I try to get into games most of the time I hea rnothing on the set. There were a few times were I could hear others talking, but when I tried to speak no one ever responded, I have no indication at all as to if my mic is working. Can someone help me out please?!
