And honestly, I tend to like open cans a bit more. I was hell bent on going for closed, but I've tried both now, and I love open. My house is generally pretty quiet, and even if you have a little outside noise, it doesn't effect what you're listening to. There's just a little better clarity you get with opens.
That's me telling you to not get 280s.

HEADPHONES THEY ARE CALLED HEADPHONES GOD DAMNIT PEOPLE
555's are good, but they're not the end-all of headphones. SR60-80's are said to be more up front and center of the music which works out well for metal and rock music, same with MS-1's. SR60's are real easy to drive at 32ohms, but so are the 555's at 50hms. Given all that, everyone who has grados say they are less comfy to wear for longer periods of time then 555's.
I own a pair of 555's and they're nice headphones. I don't see the point in getting a pair to drive them with an ipod though, if that's gonna be your sole source.
