Experience superior hearing protection and all-day comfort with the 3M™ PELTOR™ Optime™ 105 Earmuffs (H10A). Designed for demanding industrial and military environments, these earmuffs deliver a Noise Reduction Rating (NRR) of 30 dB and are CSA Class AL certified, making them ideal for high-noise applications up to 105 dBA.
