points to the corner of your mouth. The boom can be shaped to follow the curvature of your
face.
NOTE The headset is designed for the boom to be worn on the left side of your face. To wear the
headset so the boom is on the right side, rotate the microphone boom upwards until it aligns with
the right corner of your mouth. Left and right audio channels will be switched.
