If Your Pro Hear™ Whistles
Whistling/squealing may sometimes occur as you cup your hand over your
ear and adjust the volume control. This action directs sound leaking from
the ear plug into the microphone, resulting in a whistle. This should
disappear when you take your hand away. If not, check to make sure the ear
plug is inserted properly.
