I had the old version of these and they were good
My friend had these and they are similar to the ones that came with my walkman phone and are also very good.
I heard the sennheiser ones were very good. I have two pairs of sennheiser headphones - one wireless and one wired, they're both good, with plenty of good feedback about both from other people [reviews on amazon is the reason i purchased them].
I could do with some better in-earphones, the ones that came with my sansa mp3 player pull apart so aren't suitable for work, and the philips ones i bought instead are very good but the rubber surround on the ear piece is getting lose.
I'd walk around with white headphones and a shitty mp3 player, just to piss them off....did you see that look of disappointment when they found out it wasn't an ipod! ha!
