So basically, expensive = overrated? Anything in the high end you don't think it is?
When they release an expensive headphone I prefer to the HD600 I'll get back to you. A modded HD800 is the closest so far. Maybe the 007/009 might be worth it but I can't say.
It's not the price it's the fact that at the price you can't have glaring faults that many less expensive headphones don't have.
