I used them fot many years and still do, but they have to take 2nd place now to my latest addition: Sennheiser HD-600. The Beyer is less dynamic, less open, with a darker sound and the bass a little more undefined. Apart from that, still a good pair of cans, and very comfortable.
You can listen to them for hours without fatigue
It's lacking a bit in dynamics; bass is a little woollen
