I recently bought a new pair of headphones which have iPhone controls (for playing music/skipping forward back, and for answering calls, etc...) but when I plugged them in to try and use them the control doesnt work. I can't pause music/skip tracks etc. Haven't tried it with calls though. I dug up my old headphones that came with the phone that apple makes, and same thing, no response to the remote. So for some reason the phone is not responding to the button controls. Anyone else have this problem? Could it be a bad headphone jack on the phone?
