I have the headphones now about 1 month and absolutely love it. The build quality is outstanding and the sound in this price range absolutely unbeatable. Especially pleasantly I feel the full decoupling of external influences such. As street noise or beside me telefonierende family members. And, equally, I disturb anyone when I hear "my" music. You have to go with the ear to the outer side of the headphones in order to hear what the one who aufhat the headphones, just listen to quite near. Would I buy again at any time. Compared to eg Sennheiser Momentum and shoulders.
