They sit pleasantly - the pressure is sufficient. Sonically, these headphones are for the price really very good and balanced. The tips are not so clearly transmitted, as in the half-open AKG K701, the bass and the means presence, however, is easily evaluated. A good all-rounder. Sonically, I find this better than the AKG K271 Studio (also closed), which I used before.
The 80Ohm version is in my opinion very good choice. Those who work with strong Amps, may then resort to 250Ohm version.
