3M PELTOR Optime III H540A-411-SV Professional Noise-Canceling Headphones, SNR 34 dB, Black/Red

The 3M™ PELTOR™ Optime™ III H540A-411-SV are high-performance professional ear muffs designed to provide superior hearing protection in extremely noisy work environments. With an SNR attenuation rating of 34 dB and compliance with the EN 352-1:2020 standard, they are an ideal solution for professionals working in construction, manufacturing, maintenance, transportation, mining, and around high-noise machinery.

The unique double-shell technology helps minimize resonance inside the ear cups, ensuring high attenuation even at high frequencies. The spacious ear cups help reduce heat and moisture buildup, while the wide, soft foam sealing rings distribute pressure evenly around the ears to provide greater comfort even during extended periods of use.

The headband ensures a stable and practical fit while working, and the foam cushions and inserts can be replaced using the 3M HY54 hygiene kit, helping to extend the ear muffs’ service life. The 3M PELTOR Optime III in black/red are particularly suitable for grinding, sanding, welding, demolition, assembly, and plant maintenance operations, as well as in airports, power plants, engine rooms, and other professional environments characterized by very high noise levels.
