At the top of the hearing protection product list are the electronic ear muffs. Powered by two AA batteries, these noise canceling ear muffs provide 30dB of protection (in neutral position) while amplifying surrounding voices, signals, and warnings.
This combination makes these electronic ear muffs excellent for lumberjacks (especially those using chain saws), on construction sites, noisy factory floors, while snowmobiling and at the shooting range.
