Really really good monitoring headphone. I tried the Premium Edition first, which is more loose on the head so the clamping force is lesser than the Pro edition. One of the difference is coiled cable, which is really important if you are working in the studio and there are many devices-cables around. One problem I have is the right ear sometimes distort, and I can't understand is it because of the drive or because the clamp force is not enough there. But still it's a really good headphone, especially for these price range. Would recommend to anyone who are looking for a nice monitoring cans.
