The 3M™ PELTOR™ Optime™ 105 Earmuffs are engineered for reliable, high-performance hearing protection in environments with noise levels up to 105 dBA. Featuring a unique double-shell earcup design, these earmuffs deliver a Noise Reduction Rating (NRR) of 30 dB for superior attenuation across both low and high frequencies. The stainless-steel headband maintains consistent pressure for a secure fit, while the soft, liquid- and foam-filled cushions ensure long-lasting comfort throughout extended shifts. The bright hi-viz green color enhances visibility and safety on busy worksites, making them ideal for industrial applications where both protection and awareness matter.

Key Features

High-Performance Noise Attenuation: Double-shell earcup design provides up to 30 dB NRR, ideal for extremely loud environments.
Durable Construction: Stainless-steel headband resists bending, warping, and maintains consistent tension for long-term reliability.
All-Day Comfort: Liquid- and foam-filled cushions form a tight yet comfortable seal against the head, reducing pressure points.
Enhanced Visibility: Hi-viz green and black finish improves worker awareness and safety in high-traffic areas.
Adjustable Over-the-Head Fit: Pivoting earcups tilt for a secure, ergonomic fit across a wide range of head sizes.
Easy Maintenance: Replaceable cushions and liners compatible with the 3M™ PELTOR™ Hygiene Kit HY54.
Testable Fit: Compatible with the 3M™ E-A-Rfit™ Dual-Ear Validation System for objective protection level testing.
