Newegg has the Sennheisher HD 280 Pros at $80 today. Which is $20 lower than I have ever seen them at a reputable dealer.
They deliver more isolation than the Sony 7506's. I have a friend who is a sound mixer for film and tv and immediately after he tried the Sennheisher's he noticed how much more they isolate than the Sonys which uses daily. They are bigger and bulkier though and made of plastic where the 7506's are metal.

If you get them, these phones require a lot of break in time, so buy from a store with a good return policy. Immediately out of the box, the highs were very harsh, I hooked them to a CD player and played some bass-heavy music and left them in a drawer for four days. You can notice the difference in the bass and the highs.
