OP, sorry to hear that you find a Beyer uncomfortable--they certainly are a safe choice for many where comfort is concerned, myself included. That said, I'd like to second the suggestion to try the HD800; if the T1 doesn't fit you, it doesn't fit you. I've gotten rid of cans that sounded good to me but were too loose (AD300) or too tight (Shure 440), and I don't believe you ought to force yourself to fit the product. The product ought to be a fit for you.
Out of curiosity, why did you decide to go from a 555 to a T1 instead of an 800?
