Query: Uncomfortable, hurts my ears

after 2 hours of wearing these bad boys, my ears are tender and erythematous. The sound quality is fabulous, but the physical discomfort is a pain.Perhaps I just need to get used to them, or "break 'em in" or something like that.Correction 1/1/07: now that I have gotten used to them, they are great. no longer hurts my ears even one bit. great cans; highly recommended. The nice frequency response range is great for hearing the ever-so-tough systolic click murmur of mitral valve prolapse.
