Sorry for another thread on this but these just came on line for 30% off - AKG K271 Studio Closed Headphones.
I need the following features:
1. Closed back (no leakage)
2. Flat response
3. hours of comfort
--will this set do the trick or is there something else right now better (I have been using the Seinh. HD pro 280's and aside from being amped on the bass end, worked well to date.)
