What would be the most comfortable while still good sounding headphones I could get to use while trying to sleep? Right now I have a pair of Sennheiser PX200's, and although they have a decent amount of padding they're still not at all comfortable. I'm thinking ear buds might be the way to go, such as the Etymotic ER-6's possibly, but I've never had anything like those before and I'd rather not spend that kind of money on something that will be even worse to sleep with on then the ones I have now. Are earbuds the way to go? Any other suggestions about what kind, or a better alternative all together?
