Abstract An integrally formed earmold is provided which supports a headset or stethoscope, for example, without requiring either a headband or arms extending into the ear canal. The earmold is formed from a soft, flexible elastic plastic and has an inwardly extending conical portion adapted to fit into the concha and outer portion of the auditory canal, terminating in a rectangular knob with a small flange thereon, the knob sealing off the meatus of the external ear canal without substantially penetrating the external ear canal. A hollow cylinder extends laterally from the knob a sufficient distance to form a support for a headset or the like. The earmold is sufficiently flexible that standard sizes will fit the general population, without requiring molds formed for particular users.
An integrally formed earmold having thin walls and having an inwardly extending conical portion adapted to fit into a concha and outer portion of an auditory canal, terminating in a rectangular knob with a small flange thereon, said knob sealing off a meatus of an external ear canal without substantially penetrating the external ear canal, said flange anchoring an earmold at the entrance of the external ear canal, and a hollow cylinder extending laterally from said knob a sufficient distance to form a support for a headset, said integrally formed earmold being made of a soft, flexible, elastic plastic.
