Pros: Organic tonality. Tight, deep, powerful bass. Great all-rounder. Solid, attractive build.
Cons: Heavy. Lacks that last bit of openness and delicacy.
A large, hefty bit of planar magnetic goodness. Wood, metal and leather construction is very nice. A bit heavy for prolonged use though, can cause discomfort on top of your head.
It has already been said. Fantastic bass that should appeal to everyone, a very smooth and full-bodied midrange and a pleasant, nonobtrusive natural sounding treble. Very refined with low distortion and high detail, if not quite as spectacular in this regard as electrostatics. Some may find them a little to the dark side, lacking that airy openness.
I think this is the best choice below $1000. I prefer them to most.
