ABSTRACT:
Disclosed is an earset assembly that has a housing having a microphone port and a speaker port. A microphone is enclosed by the housing and has first and second input ports. The first input port is acoustically coupled to the microphone port to detect air pressure changes of the ear of a user. A speaker is enclosed by the housing and has an output port acoustically coupled to the speaker port to broadcast sounds to the user. The output port is acoustically coupled to the second input port of the microphone so that the microphone cancels at least a portion of feedback from the sounds broadcast by the speaker and detected at the first input port of the microphone.
