Yeah, Headphones not playing properly!

This is happening to me at the moment. Basically the headphones are plugged in and there are no lows in the sounds, it sounds like a crappy viral sound all digital and tinny. Then when you move the balance slider in the headphones menu in sound in system preferences, the sound seems to play all right? Im unsure if this can be fixed with some sort of driver reinstallation for the sound, because it plays find through the speakers?
