Abstract
Abstract A miniaturized headset of the post-auricle type is disclosed. The headset microphone may be located in the capsule, or at the end of a swivelable boom near the wearer's mouth. In either case, the headset capsule is contoured to fit over the mastoid process of the skull, in order to provide better weight distribution, comfort and stability. The headset capsule is further contoured by providing a front-to-back concavity in the upper portions of the capsule's sides, so as to generally conform to the curvature of the wearer's head.
