I've heard pretty much every headphone released by Sennheiser prior to the HD800 with all sorts of equipment both at my home and at meets, and while I love the HE90 and HE60, most of the others are not my cup of tea. That said, they are very comfortable, and as such I've recommended their headphones to friends in the past who are looking for TV/computer headphones for movies and video games. I'm definately not a fan of their new styling, but I'll give the HD700 and HD800 an honest listen when I get the opportunity.
Didn't have access to the forums at work for a while and have been crazy busy for the last two years. How have you been? Where are you living now? I'm still using the K340 as my main headphone, but picked up a pair of K271's for the subway and recently got a pair of Symphones Magnums that I'm slowly falling in love with.
EDIT: AKG is making $1300 canalphones now? Oh, the humanity!
