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

NRR 30dB. Twin-Cup™ Technology. Engineered for Extreme Noise up to 105 dBA.

The 3M™ PELTOR™ Optime™ 105 is the professional standard for hearing protection in environments where noise levels reach critical peaks. Designed for those working around jet engines, heavy rock drills, and industrial grinding, the H10A utilizes a proprietary double-shell technology to minimize resonance and maximize high-frequency attenuation. This "twin-cup" design provides a level of protection that single-shell muffs simply cannot match.

Despite its heavy-duty performance, the Optime 105 is built for all-day wear. The stainless steel headband maintains consistent pressure, while the liquid-filled cushions ensure a soft, low-pressure seal that stays comfortable from the start of the shift to the end.

Key Features & Professional Benefits:

• Extreme NRR 30dB Protection: Specifically developed for effective hearing protection in the most demanding noise environments up to 105 dBA.
• Patented Twin-Cup™ Design: Features two cups connected by a foam inner layer to effectively reduce both high and low-frequency noise.
• Stainless Steel Construction: The durable headband resists bending and warping, ensuring the earmuffs maintain a consistent, reliable seal over years of use.
• Liquid/Foam-Filled Cushions: Large, soft cushions distribute pressure evenly, providing a comfortable seal even for users who wear safety glasses.
• Four-Point Suspension: The headband design distributes weight effectively, preventing "hot spots" and making these muffs feel lighter during long-term wear.
• Professional Durability: Built to withstand the harsh conditions of industrial jobsites, including exposure to moisture, dust, and temperature extremes.
• Over-the-Head Design: The adjustable headband offers a customizable fit for various head sizes, ensuring a secure seal for every member of the crew.
