ABSTRACT:
A spacing device which holds earphones away from the ears to create a sense of live music when the earphones are used in conjunction with loudspeakers. The spacers allow sound from loudspeakers set away from the user to reach the ear from all directions. A volume control connected between the earphones and amplifier provides sound level adjustment for creating an optimal condition of presence as sensed by the listener.
