I've got Sennheiser HD 200s, which I use. Quit like um although I haven't tried any other head phone to be honest with you so I can't compare.
Just thought that if I spent over a certain amount then they were sure to be good.
over the last month or so, while my monitors were off for repair i got the best part of a new track down using only HD25's - i got my monitors back last week, plugged em in & hey presto...the new track written using only headphones sounds Ace!!
personally i find headphones too tiring in the long run, but once you know your sounds you can just use the headphones to crack on with writing of the music & then mix it later.
