3M™ PELTOR™ Optime™ 105 Behind-the-Head Earmuffs – H10B

The 3M™ H10B Optime™ 105 is a high-performance hearing protector designed for extreme noise environments where head-mounted equipment is required. Featuring a unique behind-the-head (neckband) design, these earmuffs provide maximum attenuation for noise levels up to 105 dBA without interfering with face shields, welding helmets, or non-slotted hard hats.

Key Features & Benefits

• Versatile Behind-the-Head Style: The neckband design is perfect for workers who need to wear full-brim hard hats, head-mounted welding shields, or other headgear that prevents the use of a standard over-the-head band.

• Double-Shell Technology: Utilizes a "sandwich" cup construction to minimize resonance and significantly boost noise-blocking ability across all frequencies.

• Superior NRR Protection: Offers a robust Noise Reduction Rating (NRR) of 29 dB*, providing elite-level safety in the loudest industrial settings.

• Proprietary Dual-Cup Design: Two cups connected via a soft foam layer provide high attenuation and outstanding comfort for extended wear.

• Consistent Seal: Soft, foam-filled cushions ensure a low-pressure, consistent acoustic seal, maintaining protection even when the wearer is in motion.

*3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided in real-world workplace settings.

Ideal Applications

The 3M H10B is the ideal choice for specialized industrial roles, including:

• Welding & Grinding: Fits comfortably under welding helmets and grinding shields.

• Airports & Tarmacs: Protection for ground crews wearing specialized headgear.

• Oil & Gas: Critical for workers on rigs using full-brim safety hats.

• Heavy Construction: Ideal for environments requiring simultaneous use of various face and head protection.
