Why is my headphone jack acting weird?

[AC Question]

For some reason after attending cheer competition, my headphone jack will not work the same. I have thried two different types of headphones and they both do the same thing. I can hear, but it plays more of the background music than the lyrics. It is as if it has water damage but it doesn't. It has never done this before.

Welcome to Android Central! Make sure there isn't any debris in the jack, like lint. Use a damp toothpick to root around, or a can of compressed air to blow it out.
