I owned the KRK for a short while.
I thought ergonomically it was a very nice headphone. It was closer to neutral than a lot of other closed headphones in the price range and isolated at an acceptable level.
If you've read my notes on the KRK... there's no need to repeat myself haha. I did like that headphone... much more than the 940, probably not quite as much as the (twice as expensive) Z1000
