Last night, I was watching a movie on my iPod, and I wanted to turn up the sound. So, I used the Remote and Mic. It didn't work, none of the buttons worked. So, I un-plugged then plugged it back in, and it still didn't work. I did a respring, and it still didn't work. So, I continued watching. Then I tried unplugging it, and plugging it. My iPod did recognise the headphones being unplugged, and kept playing the movie. It didn't pause, and go to the speakers like it usually does. The problem has stopped now, but this is the second time it has happened. What should I do?
