Got a used pair of the black version at 450 USD. Very good sound, but the black paint is fading and these are uncomfortable. They weigh less than LCD-2, but feels heavier. It's weird that even LCD-2 are much more comfortable, comparing with Vali.
However, I'd love to keep these - every aspect matches my impression of Russia. Now I have a collection of headphones from 12 countries. Cheers!
