Engineered for high-noise environments, the 3M™ PELTOR™ Optime™ 105 Earmuffs – H10P3E deliver maximum hearing protection with a Noise Reduction Rating (NRR) of 27 dB. These hard hat attached earmuffs feature a double-shell cup design with an internal foam layer that enhances attenuation across a broad range of low and high frequencies. Designed for compatibility with most safety helmets, this cap-mount model integrates easily into a worker's PPE setup. Soft liquid/foam cushions, pivoting earcup points, and a lightweight stainless steel construction contribute to a secure yet comfortable fit, making these earmuffs ideal for extended wear in noisy industrial conditions.
