摘要： The present invention relates to a headphone apparatus which is adapted to be connected, for headphone listening, to a reproduction apparatus for reproducing a program source such as a record, a magnetic tape or an acoustic apparatus such as a radio receiving set. In accordance with the present invention, there is provided a headphone apparatus in which a direct audio frequency signal as an output signal from the electroacoustic apparatus is applied to reverberation circuits to generate indirect audio frequency signals and these direct and indirect audio frequency signals are mixed and applied to both the left and right electroacoustic transducers of the headphone apparatus, whereby an acoustic image can be established outside the listener's head just as in the case of listening to speakers.
