Abstract (en)
[origin: EP0033769A2] The invention relates to a headphone demonstration system in which a set of headphones is mounted suspended from a connecting piece which is lockable to a current rail under a corresponding lead pick-off and can be separated from this again. The current rail can be mounted on a ceiling or side wall of a room, stand or such like, and is connected to a demonstration system associated with the set of headphones. The system is space-saving and, in particular, allows a simple variation of the number and position of headphones. <IMAGE>
