Good earbud headphones

As the title implies, I need some good earbud headphones. Actually, I want some good ones, but close enough. Any suggestions? I’ll be using them connected to my iPod (I lost the stock 'phones and figure as long as I’m getting new ones, I may as well get good new ones) if that makes any difference.

The [http://www.shure.com/earphones/eseries_why.asp]Shure E2C is supposed to be a very good mid-priced ear bud. These actually sit in your ear canal, giving you better noise isolation and better sound.

Or, you can go all the way up to the dual-speaker E5C models, which cost hundreds of dollars.
