Anyone who follows this thread knows it won't be too long before this changes.
As kind of a sidebar in regards to comfort, it is certainly an important thing, but everyone is going to have different experiences as far as that goes. The Annie disappears on my head. I don't even notice I'm wearing them half the time. I have a pair of CALs that never caused any problems. My FA-003 clones can get a bit hot at times, but only on the hottest days. I also have a FA-004 clone (can get uncomfortable after long sessions, 3+ hours), G930, and Sennheiser PC150 that haven't caused any problems and are generally very comfortable.
The most offensive headphone I have is the Monoprice 8323. That headband is just torture. The earpads are also uncomfortable after a short amount of time.
