Ive had these since back in the mid-80s but have seldom used them so they are still in very good condition. The adaptor box connects directly to your amplifiers speaker cable outlets and your speaker cables connect to the back of the adaptor box. A knob on the front of the adaptor box enables you to switch between earspeakers and loudspeakers. Enjoy the clear high-end definition of electret without disturbing the neighbours.
