I bought thesehttp://www.amazon.com/Sennheiser-Momentu...ntum+headphones
They came in today.. I figured that i would give them a try for a bit, i listened to them a little bit today... i'll take them to the office on Thursday and spend some time with them....
Closed headphones was a must, due to the primary purpose is for the office.
If for some reason I'm not happy with the Sennheiser's i think the Denon AH-D5000's will be next.. However, my initial impression of the Sennheiser's is that they are pretty a pretty impressive pair of headphones..
