Its been a month since I first got my hands on these headphones. As always sennheiser have done a great work with this headphones, they have a great feel and they feel so soft on ears. And the sound is fantastic, the have a great bass. The blue rim over the ear cups looks magnificent.
They may look heavy but they are not, you can use them for hours but they yours still wont heart. In the price range of 4K they are the best headphones.
