I have got quite a pickle here. I was using my headphones to watch some stuff, I set them down, and then decide to go render out a mix. But when I listen to it, the mix sounds completely different. When I check other songs, it sounds similar. It seems to be a bit muffled, and tinny. I have no idea what happened. When I plug them in to my laptop and mp3 player, it doesn't seem to sound like this, yet my other in-ear headphones don't sound like this when I plug them into my interface. I'm so confused. Do you all know what could have happened?

EDIT: After listening to my mp3 and laptop more, it seems like it does it when I use the headphones, but not quite as bad. So it's most likely the headphones. But I'm still confused. Does anyone have an idea of what happened?
