What can I do to fix quiet EarPods?

My Apple EarPods recently had the sound go quieter on them. The right side, main mesh part has the least amount of sound but the other places are loosing it too. I take good care of my EarPods, and the only thing that could have contributed to this problem was that they were dangling as I was walking but only for a few seconds. Instead of having my volume on my iPod touch and iPad around 2-3, I now have to have it at 5-6 to achieve the sound volume I need. I could be loosing hearing because I don't have very good ears, but I'm only 13.
