Have you ever tried to listen to music or watch a movie with a pair of headphones that only work on one side? It's pretty miserable, isn't it? (Every parent who has ever made the mistake of sharing his headphones with his kids is nodding sadly right now.) Obviously it's time for you to order a new, higher quality pair of headphones and hide them from your destructive offspring. In the meantime, you can enjoy the full audio experience by switching your iPhone or iPad's audio settings to mono.
