Maximum Protection for the Noisiest Industrial Environments

The 3M Peltor Optime III H540B delivers serious hearing protection where you need it most. With an SNR 34dB rating, this is one of the highest-rated hearing defenders available. Designed for environments hitting 95-110dB – think construction sites, manufacturing floors, and aviation ground operations. The neckband design sits comfortably under hard hats and helmets, so you're not choosing between head protection and hearing protection.

Key Features:

• Double-Casing Technology: Advanced acoustic design minimises resonance for maximum high-frequency attenuation. You get serious noise reduction without losing the ability to hear speech and warning signals – critical for staying safe on busy sites.
  
• SNR 34dB Protection: One of the highest Single Number Ratings you'll find. Handles extreme noise levels from 95-110dB, making this the go-to choice for the toughest industrial environments.
  
• Exceptional Low-Frequency Attenuation: The acoustic connection between the inner volume and the space between casings provides outstanding low-frequency noise reduction. Tackles the deep rumble that other defenders miss.
  
• Extended Comfort Design: Broad sealing rings filled with soft plastic foam create an optimal seal with surprisingly low contact pressure. Comfortable enough for all-day wear without the headache.
  
• Neckband Configuration: Worn behind the neck, this design pairs perfectly with helmets, hard hats, and other head protection. No interference, no compromise.
  
• CE Certified: Manufactured by 3M Personal Safety Division in Wroclaw, Poland. Meets the latest European safety standards, so you know it's properly tested and certified.
