Abstract
Abstract A self-supporting headset is disclosed with a housing adapted to accommodate a receiver and microphone. The headset housing comfortably supports itself on the upper portion of an ear of the user. A flexible acoustic tube together with an adjustable voice tube are mounted on an upper portion of the housing forward of the user''s ear. The acoustic tube curves backwardly to provide communication between the auditory canal of the user''s ear and the receiver through a tube along the inner periphery of the housing. The voice tube provides communication between the user''s mouth and the microphone. Electrical signals are carried to and from the microphone and receiver through a pin and socket connection together with a strain relief collar device mounting a lead wire cable to the housing.
