I've got some Sennheiser HD 25-SP, and they're awesome. To be honest they're a lot more atmospheric than my Logitech Z-680 speakers, although I think that I paid about £65 for the headphones when I picked them up a couple of years ago, which might be a tad expensive (if you don't think so then I'd advise going for the £100+ HD25 which have a better headband and only a single lead over the 25-SPs twin).
