I just purchased these headphones to replace my old Sony MDR-V150 pair and I have yet to find fault with them. I'm doing the burn in now. They seem to sound better and better. I'm planning on using them for personal recording and some live mixing. I'll come back in about a month and edit this. 

I bought these headphones a while back and I enjoy them somewhat. They have good sound if you need a set of studio monitors on the cheap. I don't think I would recommend them to anyone.
