The Sony NX-1's are pretty good if you have a small mp3 player, you can attatch it to the bottom, i have a pair, they're pretty good, but sometimes you may find them a little underpowered, they dont feel as 'punchy' as the EX-71's although your looking at a big diff in price.

I reckon if you dont mind the price then go for the EX-81's. Mind that if you do go for the NX-1's be prepared for some wire tangles, there's a lot with the neckstrap and all that. And the white is gets dirty quickly, be prepared to clean them every month or so.
