3M™ PELTOR™ Optime™ 105 Earmuffs – H10A Over-the-Head

The 3M™ H10A Optime™ 105 is a premier, high-performance hearing protector engineered for extreme noise environments. Utilizing a proprietary dual-cup design, these earmuffs offer superior attenuation across a wide range of frequencies, making them one of the most effective solutions for noise levels up to 105 dBA.

Key Features & Benefits

• Double-Shell Technology: Features a "sandwich" cup design where two cups are connected via a soft foam layer. This innovation minimizes resonance and boosts the earmuff's noise-blocking capability.

• High NRR Protection: Provides a Noise Reduction Rating (NRR) of 30 dB*, providing elite-level safety for the loudest industrial settings.

• Outstanding Comfort: Equipped with soft, foam-filled cushions that provide a consistent acoustic seal and low-pressure fit for extended wear.

• Stainless Steel Headband: The robust over-the-head headband resists bending and warping while maintaining a consistent clamping force.

• Multi-Industry Utility: Designed for reliability in high-stakes sectors, including airports, oil and gas, and heavy manufacturing.

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

Ideal Applications

The 3M H10A is the industry standard for environments with severe noise exposure, such as:

• Aviation: Ground support, engine maintenance, and tarmac operations.

• Heavy Manufacturing: Metal stamping, forging, and foundry work.

• Energy & Mining: Oil rigs, gas processing, and rock drilling.

• Food & Beverage: High-speed bottling lines and large-scale processing plants.
