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.

1. An ear mounted earphone for use by a user having an ear with an entrance to an auditory canal therein, comprising a speaker; a speaker housing mounting the speaker; an elongate boom extending from the speaker housing; ear mounting means having ends and a curved intermediate portion, the intermediate portion configured to fit behind the ear of a user between the user's head and ear with one end extending over an upper portion of the user's ear; sleeve means in the end of the ear mounting means extending over an upper portion of the user's ear for frictionally holding the boom therein and allowing forced sliding of the boom in the sleeve longitudinally to adjust positioning of the speaker housing with respect to the mounting means and forced rotation of the boom in the sleeve means to adjust orientation of the speaker housing with respect to the mounting means; a stop at the end remote from the housing to prevent the boom from sliding completely through the sleeve and separating from the ear mounting means, whereby the ear mounting means in combination with the speaker housing and boom will cooperate with a user's ear to position and hold the speaker at the entrance of the user's auditory canal; and wherein a wire extends from the ear mounting means, through the boom, and into the speaker housing to connect with the speaker.
