My personal recommendation, depending on your needs, would be to go with one of the larger open Sennheisers (485 would be one model). A few dollars more, but some definite advantages over the 280s.
I have a pair of 280s that I got for use on planes and stuff where it's noisy, and that's about all I can use them for. Because they're sealed, you lose a bit of bass response, but the worst thing to me about the design is cord noise. Unless you're sitting perfectly still, anything touching the cord goes straight to your ear. And isn't the reason you want a good sealed phone to block out other noises and give good music? They could have put some sort of vibration-reducing coupling in the cord or something...
I also have a pair of HD600s which are worlds better in terms of comfort, bass reproduction, and because they're open no cord noise. Wonderful headphones, a bit more than you're looking for, but some similar ones are available in the ~$100 range. Can't speak about the other brands though.
