EARMUFF PELTOR H520P3GS/E HELMET ATTACH

Experience reliable, high-level hearing protection with 3M™ PELTOR™ Optime™ II Earmuffs, engineered for demanding noise-hazard environments such as construction, mining, heavy industry, and aviation. Designed to attach directly to most 25mm and 30mm slot hard hats, these earmuffs deliver professional-grade noise reduction with an SLC₈₀ rating of 29 dB (Class 5) — effectively muffling even low-frequency industrial noise.

The dual-moulded ABS earcups and soft, wide cushions provide a comfortable, secure fit, while the large internal cup space helps minimise heat and moisture build-up, making them ideal for long shifts in hot or high-noise environments. Easy-to-replace hygiene kits extend product life and maintain comfort and performance over time.

With their proven design and superior acoustic sealing, the Optime™ II Earmuffs are the go-to choice for workers who rely on consistent hearing protection day after day.
