BPHS1 is a rugged stereo headset that offers natural, highly intelligible and focused vocal reproduction, closed-back circumaural (around-the-ear) ear cups to seal out background noise. The headsets microphone has a cardioid polar pattern tailored for pickup of speech with maximum voice intelligibility over a wide range of frequencies. It is more sensitive to sound originating directly in front of the element, making it useful in reducing pickup of unwanted sounds. The flexible gooseneck boom swivels for easy positioning on either the right or left side.
