3M H10A Optime 105 Hearing Protection

The 3M™ PELTOR™ Optime™ 105 Earmuffs (H10P3E) provide reliable hearing protection in high-noise industrial environments. With an NRR of 27 dB and an over the head design, these earmuffs are ideal for workers using hard hats in construction, manufacturing, oil & gas, and other heavy-duty settings.

Built with 3M’s double-shell technology and a proprietary dual-cup design, these earmuffs reduce both high- and low-frequency sounds while maintaining exceptional comfort. Foam-filled cushions offer a secure seal for long-term wear, and the integrated design allows for easy use with most standard hard hats.
