Modern M30 active ear protectors, manufactured by Earmor. The reliable noise cancellation mechanism helps protect ears in noisy environments, and in particular protects against the intense sound of gunshots during shooting training. At the same time, they amplify low-frequency sounds for easier communication and safety. Robustly made headphones with foldable, adjustable arms that make them fit easily into backpacks or shooting equipment bags. The low-profile housing is made of 3mm-thick polycarbonate, which makes it impact-resistant and won't interfere when used with long guns.
