A mate bought the Shures when he bought his first iPod. He went through three sets, each with the same problem. In the end I suggested the Denon AH-C525's, which had just come out. Two years on, still going fine, chuffed to bits with them. I had some cheap CX300's, which were ok, got some ER6i's with custom eartips, which are fine, but a phaff to put in and take out, which is an issue at work, 'cos I use them as ear protection when I'm running noisy machines, so I got some Ultimate Ears which lasted six months before a wire broke, now got a pair of Denon AH-C252's, which cost me £25, and I can't say enough good things about. Perhaps not quite as finely detailed as the more expensive phones, but still a nice clean sound, great bass, really comfortable when worn all day, and they're cheap. Can't recommend them highly enough.
