Well, I compared to the HD600 as well... HD600 are perfectly fine, versatile and balanced sounding (little slow and not airy and expansive in terms of soundstage but fine), HD650 are not. HD650 are specific, love it or hate it type of headphone.
I am not saying that HD650 are bad... Well, they are bad subjectively for me... But that's not important. What IS important is NOT to deny that HD650 are slowish and veiled sounding headphones in comparison to the majority of audiophile offerings. I have heard a lot of mid-fi or high end headphones and HD650 were really the slowest I've heard so far. There is always some sort of a veil regardless of what you are listening... It's not what I would call transparent and reference type of sound for critical listening.
