Recently my phone has been acting weird when my call/play/pause button equipped headphones (Nuforce Ne-7m's) are in...without me actively doing anything it starts to play and pause and part shuffle on its own, and I hear scratchy noises whenever the plug is moved. Is my headphone jack loose or is there something else going on? I don't think its the headphones, they didn't seem to do anything like that to an ipod touch.
