A while back there was a thread on here discussing good, reasonably cheap headphones, but I can't find it anymore. I would like to get a decent set of headphones (probably of the "in ear" variety). Anybody have recommendations for something in the not too expensive (definitely less than $100 and preferably closer to $50) category or a link to the thread I am thinking of? They will be used primarily hooked up to a computer to evaluate mp3 quality before adding to my collection so snazzier features like noise canceling are not necessary.

Thanks,
