I own a pair actually. I got them on ebay a few months ago. I don't have them on hand right now as I have been out of town for a month and they are not with me, so I have to go off memory, this weekend Ill be able to listen to them again though. They are part of the HD 600 family of headphones and share interchangeable parts with other HD 6xx headphones. Except these are 150 ohms instead of 300 ohms. As for the sound, they are quite neutral and lack a bit of sub-bass extension, they have a warmth and richness to the midrange that is typical of headphones in the HD 600 family. With the stock cable I found the treble to actually be a bit rough but that roughness went away when I changed to a better cable. Soundstage is about average in size, it's not huge but does have good depth. It images quite well.  They are on the forgiving side, lesser quality tracks sound better on them than other high quality headphones I have owned.
 
Although something to note about the older HD 600 family is that there is a channel dropping issue that can happen, this happens because the springs that connect the cable to the driver become stretched out and start losing connection easier over time. To fix this the springs need to be replace, there is an video by Tyll from Innerfidelity showing how, going by how he accidentally damaged the driver in the video I would be cautious with this repair. I have this problem with my pair, it's not much of a problem but can happen time to time especially when moving around a lot. I may eventually replace the springs but not anytime soon.
