3M PELTOR Optime III Ear Defender with Neckband, 34 dB Noise Reduction, Black H540B-412

3M PELTOR H540B-412 Optime III Ear Defender with Neckband is engineered for superior hearing protection with an SNR of 34 dB, ideal for environments with extreme noise levels such as power stations, airports, mining, and industrial printing.

Manufactured with durable plastic and stainless steel, the double-cup technology reduces resonance, delivering maximum high-frequency insulation. The generous internal space minimizes heat and moisture, enhancing user comfort during long-term use.

The adjustable neckband ensures compatibility with helmets and visors without compromising fit. Soft wide cushions reduce pressure around the ears for prolonged comfort in tough working conditions.

Replacement foam ear pads (part number 449-6607) should be fitted approximately every six months to retain effective protection and hygiene. These Ear Defenders meet CE and EN 352-1 standards, confirming compliance with safety regulations.

Common applications include quarrying, aerospace industry, printworks, power stations, and marine engine rooms. The light weight of 270 grams reduces fatigue and increases wearability.

Durable plastic and stainless steel materials provide robustness. Double casing technology minimizes resonance within ear cups. Large internal ear cup volume reduces heat and moisture build-up. Foam pads are replaceable to maintain hygiene and protection.

Adjustable neckband fits securely around the neck for convenience. Certified to CE and EN 352-1 safety standards for hearing protection. Ideal for use in loud industrial environments including mining and airports. Lightweight design ensures comfort during extended wear.
