Looking for over-ear headphones, which ones?

Hi guys,

I suppose this is Nate's field - I’m looking for some over-ear headphones; what should I buy? I’m willing to splash out up to £150 (pitiful, I know, in the audiophile world) but I’m willing to be flexible.

Thanks

Do you want open or closed cans?

Sennheiser make these HD595s which get good reviews.

i think closed, because i would mostly use them at work when they probably won't all want to hear my music. they look nice though!
