Not really, no. I have a friend in Japan who will be returning shortly and she agreed to bring some stuff along. The S500 are currently 3500Yen on amazon.co.jp which corresponds roughly to 35€. Directly ordering from amazon.co.jp is rather costly though, since they add 3000Yen for shipping to europe.
I'm a big s500 fanboy, and Doc will be putting them back to #1 spot again some day lol! So you know that my answer to your question is "yes". If you get them though, get the ath pleather pads as well which really balances out the sound and also are more comfortable than the stock pads (although I'm sure not as comfy as the uptown's pads).
The comfort is the thing that's making me think about getting the S500 or not. Also I'm not so sure about the folding stuff because it's seems liable to breaking. Especially since I plan to use the headphones more stationary then mobile, I wouldn't need the folding.
On the other hand I hear only the highest praises around the forum for these and this is a unique opportunity to get them this cheap... *argh* head-fi.org, why do you tease me so much
