The present invention includes a compact and economical construction of a microphone wherein the housing is preferably constructed of two identical halves that form a chamber in which the microphone is retained. The housing also includes first and second acoustic passages in an acoustic relationship with the first and second ports of the microphone and extending to an exterior surface of the housing. A switching mechanism is preferably rotatably secured to the housing such that when the switching mechanism is in a first position, the first and second passages are in an acoustic receptive state and when rotated to a second position only one of the acoustic passages is in an acoustic receptive state.
