The 3M™ PELTOR™ Optime™ III Earmuffs are premium high-attenuation hearing protectors designed for use in extremely noisy industrial environments where maximum hearing protection is required. Featuring advanced double-shell cup technology, the earmuffs help minimise resonance and deliver excellent low-frequency noise attenuation while maintaining wearer comfort during prolonged use. The large ear cup design includes soft wide sealing cushions and generous internal depth to reduce pressure and heat build-up around the ears. The stainless steel headband provides consistent pressure and durability, while the ergonomic design improves compatibility with additional PPE such as safety helmets and eyewear. Suitable for airports, heavy engineering, mining, power generation, manufacturing, and high-noise industrial applications, the Optime™ III earmuffs provide reliable premium hearing protection for demanding workplace conditions.
