ABSTRACT:
A baffle, which supports a driver for converting an input electrical signal into an acoustical output signal, is mounted to a headphone cup via a first cushion which sufficiently spaces the baffle from an outer ear to avoid contact. The baffle defines a front cavity and a rear cavity. A second cushion which forms an oval opening large enough to encompass the outer ear is mounted on the headphone cup for establishing an air seal between the front cavity and a region outside the headphone cup.
