The housing has a first portion sized to contain the speaker and a second portion sized to contain the directional microphone. The second portion defines a front port positioned adjacent the front surface of the directional microphone and a rear port positioned adjacent the rear surface of the directional microphone. The housing is configured to minimize the distance that sound waves travel within the housing before impacting on the sound receiving surfaces of the microphone.
