EARMUFF PELTOR H520A

Get professional-grade hearing protection with 3M™ PELTOR™ Optime™ II Earmuffs, designed for use in demanding noise-hazard environments such as construction, mining, aviation, manufacturing, and agriculture. Delivering a Class 5 (SLC₈₀ 32 dB) noise reduction rating, these earmuffs effectively reduce exposure to both high and low-frequency industrial noise — providing reliable protection and long-term comfort.

Featuring soft, wide cushions and dual-moulded ABS earcups, the H520A provides a secure seal while distributing pressure evenly around the ears, reducing fatigue during long shifts. The large internal cup space helps minimise heat and moisture build-up, while replaceable hygiene kits (cushions and inserts) extend product life and maintain consistent comfort and performance.

Lightweight yet durable, these over-the-head earmuffs are built to withstand daily industrial use and are available in the signature green/black Optime II colourway. They’re ideal for operators working with machinery, grinders, construction tools, or heavy plant equipment in high-noise environments.
