Thanks guys for all your replies. I agree, I think it is a mechanical issue because if I played with the tensions on the straps I will get the sound back, obviously, after a while of that, the connection just gave up all together. What I'm concern about is why me? I mean, it is obvious that no one else have a problem like this and I just cant believe that I'm unlucky enough to get two bad headsets one after the other with the same exact problem. Maybe the way I'm using it or the way I'm putting on and off is causing the problem, but to the best of my knowledge, I'm doing it according to Oculus directions.
