An infrared headphone with supplemental microphones to aid the hearing impaired allowing the user to hear the significant sounds from the ambient surroundings. In order to suppress the sound intensity of the user's own voice the invention provides for microphones arranged at a distance from each other on a supporting elbow in such a way that when they are mounted on the head of the user they are symmetrically arranged with respect to a median plane of the user's head and the signals emitted from the microphones are conducted in counter-phase with respect to each other.
