Considering Jude's review said that he'd comfortably recommend them at double the price, I'm very much expecting these to perform better than the HD 650. Although hype can be a powerful thing. In a perfect world these will be more fun (and much more comfortable) than my LCD 2. Worst case, they shouldn't be too hard to re-sell at minimal loss.
I've had my eyes on this set to use as a computer monitor. I wish there were more reviews but it was released just for doorbuster sales. From what I understand it's similar to the m-series but with cheaper materials to keep the costs down. Best Buy is also selling this one for $999 on BF.
As I said earlier in this thread I had the exact same problem. The HM5 pads took care of that problem completely and I love them. You can see above that they may or may not change the sound...I don't know. I can't tell any difference. You may. But they are comfy as hell now and still sound great, to me that's all that matters. EDIT- BTW here's how they look with HM5 pads in case you're wondering.
