I had that problem once, then looked at my headphones, and saw a little (L) and (R) on the edge of the headphone, seriously not making fun of you,. I have done it. what headphones do you have ? and when you think its happening did you go to "playback devices (right click on sound icon in taskbar) and tested it right there and then ?
I checked playback, no reverse audio. And if I wear them the other way, the mic faces the back of my head, which would be a major design flaw
