Ear protection
Description
The 3M PELTOR Optime III H540P3E-413-SV is a high-performance, helmet-mounted passive earmuff designed for extremely noisy industrial environments, particularly where noise is dominated by low frequencies. It features a double-casing (double-shell) cup design that minimizes resonance in the outer casing, delivering very high attenuation across the frequency range.
