So the headphones came ordered in an action. Was well packed and easy to unpack. Easy to put into operation. Quickly built a connection to the mobile phone. Kopfer is large and comfortable to wear all my only glasses you should not wear because pressing the handset too strong and the temple do at Hor hurt. The handset has a good sound but via cable he plays even more dynamic. The bass is very strong and very dynamic. The shielding is good but not great, my old inEar Sennheiser handset screens better. The shield on the train is ready but OK, first I wanted to send them back, but I have a solution for the glasses found. Strap on the handset place because they must not lose weight, only when placing the handset you have to watch something. But the most important, after a certain settling time the listener sound even more dynamic, so I keep it yet.
