The package consists of headphones and a station that is connected to the music system. Here is the good old clinker cable not in, but a connection is, at least in our modern facility, with the supplied cables, no problem. And then the batteries must be inserted into both sides of the headphones and then you can start already. The sound of these headphones is just great, otherwise you can not say it. I'm not a gigantic music connoisseur who has worked with various music systems etc., but the sound that produce these headphones, something very particular that I hear also. The range of the headphone is absolutely fine with us she goes throughout the basement when the plant is located in the living room.
