Hi All I use my Nano in my runs. It's a 5 week old nano. It suddenly start to pause or move to the next song why I'm running. I realize that it has something to do with my earphone, not Apple's original (they fall out of my ear when I run), it is a Phillips or an AKG 316K. Apparently when the lines moves it short circuit the contact and Nano understand it as some command and pauses or move the next song. Is someone else suffering with it ? How can I solve this issue ? It's really annoying.
