These are indeed great headphones (on par with HD650, K701, etc) and I bought them shortly after seeing this post. But anyone wishing to buy these needs to find out whether they're sensitive to loud treble volumes. I found out the hard way that I am quite sensitive to hot treble (others are not). With this warning out of the way, they are absolutely delightful. They even outperform HD650 with their clear, resonant bass. If only they had 650's smooth treble!
