If you are coming from many a lesser can to the HD 650, I suppose that might be (relatively) true. However, if you are coming from a can like the HD 800, T1, HE 500, Sony MDR-SA5000 or even the Q701, various Grados & Alessandros or the HD 600, you can hear the difference. In this context the HD 650 lacks air & upper harmonics and it is a tad on the slow side. It sounds that way with the Asgard 2 or a Burson. Yes it's a great can, but it has its relative weaknesses.
