Envelope to: zusammengekrunkelte headphones in plastic wrap, that's it. Ok, are so low. So unpack. Immediately noticeable is the clatter of the operating unit. The rattles correctly with every movement. So these parts are not original! OK, try. The sound is absolutely poor, the sound spectrum unacceptable, the seating comfort as such not designatable.
This product is just bad all around and an impertinence.
"Whoever buys cheap, buys expensive," proves true once again when you then consider, what the costs of the transport, is irresponsible then basically this purchase!
Stay away from this garbage !!!
