Headphonics 0/0 [1995, Ryoji Ikeda, 3:12]

+/- has a particular sonority whose quality is determined by one’s listening point in relation to the loudspeakers. Furthermore, the listener can experience a particular difference between speaker playback and headphone listening. The sound signals can be thought of in the same way as light is made spotlight. Lastly, a high frequency sound is used that the listener becomes aware of only upon its disappearance.
