Hi I just got this and he thing clamps my head real bad... I hear theres some kinda headband mod or something I could do? Anything else to help comfort? I like to use it for long periods or time at a time.. Also a question: does listening with the grados while you sleep hurt your ear?

Well after ordering the beyer 250 and waiting 3 weeks to not get them, I canceled and ordered teh senn 495 because I prefer the warmer sounds... and many have said it was more comfortable then grados.. Boy does my ear itch wearing these things.. does this get better? I thought it would go...
