I bought these on clearance back in 06. No regrets whatsoever. They are so comfortable, you'll swear they aren't even there. They sound great even with a relatively high impedance coming straight from an iPod. Most recently, I drive them with a custom kernel enabled Nexus S 4G. I have a FiiO e17 in the mail though, so I'll have to re-evaluate. 
 
They are also very visible and if someone sees you with those on your head, they wont come strike up a conversation. 
 
The only downside for me is leakage and how fragile they feel. I guess I put too much stress on the cord because one of the internal connectors actually broke off the driver on the right side. It was easy enough to re-solder, but still, thats a concern. The leakage is only a concern becuase I primarily use them at work and like to crank it up. 

Theres not a ton to say. They work pretty good, isolate ~30 dB if i recall and if you have the proper tips to fit your ears, youll be able to wear them for hours, which is good if youre using them like I was, running a floor grinding machine for 16 hours a day. Just clean them once in a while, or they'll start to look like candles.
