Abstract
An ear mounted earphone includes a speaker housing for positioning a speaker at the entrance to the auditory canal of an ear of a user. An elongate boom extends from the speaker housing and through a sleeve at one end of an earpiece so that the boom may be moved longitudinally and rotationally within the sleeve for adjustment purposes and will be frictionally held in adjusted position by the sleeve during use. A microphone arm with microphone may be rotatably mounted on the speaker housing to provide a microphone when the earphones are used with a communication system. The rotatability of the microphone arm allowing the same earphone and microphone arm to be adjusted for use with either the right or left ear of a user. An earpiece may be conveniently integrally molded as a single piece with a slit formed therein intermediate its length so the wire to the speaker and microphone can be positioned within the earpiece. The speaker may be waterproofed by a thin waterproof material such as mylar.
