Sennheiser HD439's. Sound great, are comfortable to use and didn't cost the earth. What's not to like?
I have a set of these myself and they are great. I also agree that wired are better than wireless.Sennheiser HD 598 - good old fashioned wired for me!
It is, however, interesting to see how far wireless has come on, albeit I've yet to try any wireless headphones that come anywhere near the sound quality of a decent wired set.
