3M Earmuff Optime III With Poultry Band Size 35

The 3M PELTOR OPTIME III H540A earmuffs are designed for use in extremely noisy working environments where maximum hearing protection is required. The double-shell technology reduces cup resonance and provides excellent attenuation of high-frequency noise, while the specially designed acoustic chamber enhances low-frequency noise reduction.

The spacious ear cups help reduce heat and moisture build-up, ensuring long-lasting comfort during extended use. Wide sealing cushions filled with soft foam provide a secure fit while minimizing pressure around the ears. The adjustable padded headband allows for a comfortable fit for different users.

Recommended for environments with noise levels between 95–110 dB, including airports, power plants, engine rooms, printing facilities, heavy industry, and other high-noise workplaces.
