Ive had these headphones for 3 months now and from what i've seen they are pretty great. They have great audio quality, though not the best. But are very expensive for what you get. The build is all aluminum with very soft padding, so the build quality is great. But they are a bit heavy. A lot of people say they are uncomfortable because they are on-ear not over-ear like the studios. But I must disagree. Because I have very small ears, they fit over my ears and become a over-ear headphone for me, which makes them very comfortable, but a bit heavy...
