The 3M™ PELTOR™ Optime™ 105 Earmuffs H10A are engineered for high-performance hearing protection in environments with extreme noise levels, such as airports, heavy manufacturing, mining, and oil & gas operations. Featuring a proprietary dual-cup design and double-shell technology, these earmuffs offer superior attenuation with a Noise Reduction Rating (NRR) of up to 30 dB, depending on the attachment type.
The over-the-head configuration ensures a secure and comfortable fit, while the soft, foam-filled cushions minimize pressure and enhance wearability during long shifts. Built with stainless steel construction, the headband resists bending and warping, maintaining consistent performance over time.
These earmuffs are compatible with the 3M™ E-A-Rfit™ Dual-Ear Validation System, allowing for fit testing and compliance assurance. Whether used in demolition, welding, grinding, or machine operation, the Optime™ 105 earmuffs provide reliable protection without compromising comfort.
