Be sure to *search* this site for previous threads--lots has been written about phones, including all the models mentioned. After buying and trying 6 popular makes/models this year. I kept the Senn 280s: although all the phones were decent, the Senns were the clear winner in my AB tests that focused on price ($100 range), comfort, isolation, and especially sound. Everyone has different tastes, though, so be sure to run your own comparisons in a shop or at home.
Good luck,
