This might be subject to change from person to person since ears also differ, but I don't find them unconfortable in htat way. My ears fit inside the cups comfortably and I don't feel them clamped. Of course after too much time wearing I find them a bit uncofortable but I'd say the problem is more in the diameter and the pleather pads. The foam inside is thick and can be removed which might give you a bit more room (in this case I have read sound can get altered quite a bit). Overall they are not unconfortable headphones. It's just some small details like velour pads instead of pleather reveal to improve in confort.
EDIT: So recabling is an option better left to the pros. Then, are there any other tricks that should improve the overall quality of the headphones I should know?
