3M™ Peltor™ Optime™ 101 cap-mounted earmuffs feature a stainless steel headband for consistent force and effective hearing protection. It’s imperative that workers in environments with the loudest noise have the correct level of protection as even minimal exposure can result in serious hearing damage. The Optime 101 is the right choice for these applications since it “muffl es” and attenuates noise to a safe level so individuals can function long term with less danger.
