Headphones, what kind do you use? Options

[jennyjenny]

So what kind of headphones do you use for your md/mp3/cd/etc. player?

I have these Sony earbud ones that I bought a couple years back. And I currently use these Sennheiser ones that came with my iRiver.

But I've been using my mp3 player a lot lately, and my right ear hurts now probably from using those earbud headphones.

And the quality from earbud headphones aren't that great :-\
So what do you use and are they good?
Are you planning on getting new ones?
What headphones do you suggest that aren't too bulky so I can carry around, but have good quality?

Thanks.

I use the white ones that come with my iPod. But I'm thinking about getting another better pair. The Shure ones look way too expensive, though. I'll try the Sony ones.
