Only one speaker works? Sometimes?

Question

I have two speakers and a little sub, they came in a pack. The have a cord so i can plug in my iPod. They work fine sometimes, but one speaker doesn't work all the time. When it stops working, if i move the plug around in the iPod, it starts to work again for a little bit. Can you help me?

Answer 1

Replace or repair the cord.  After a while, the copper strand inside of the cord will (since it is probably hair thin) break apart, and when you move it around, the wire will touch and make a connection, which is why it works for a while.  But of course it just pulls apart again.
