ear cups over both ears.
⚫ Slide the ear cups up or down to find the position where the ear cups
completely cover your ears. When properly installed and adjusted, the cups
should not touch the headgear shell or visor surround.

are talking in a barrel. The noises around you should not sound as loud as
