3M 247-H10A PELTOR Optime 105 Earmuffs, 30 dB, Black/Red, Over-the-Head - 1 Each

Key Features

• Dual-Cup Technology: Features a patented double-shell cup design (two cups connected by an inner foam layer) that effectively dampens and manages low, mid, and high-frequency noise.
• Maximum Attenuation: Offers an outstanding Noise Reduction Rating (NRR) of 30 dB—the highest level of protection available in the Optime™ series.
• Padded Twin-Headband: The stainless steel headband distributes weight evenly for low-pressure comfort, while the open, ventilated design reduces heat buildup over the top of the head.
• Liquid/Foam-Filled Cushions: Ultra-soft, spacious ear cushions distribute sealing pressure evenly around the ears, preventing uncomfortable "pinch points" while establishing a robust acoustic seal.
• Rugged Durability: The stainless steel wire headband resists bending and warping, ensuring consistent tension and reliable safety performance over years of use.
