## Long description

The 3M™ PELTOR™ Optime™ II Ear muffs (model H520A) are designed for demanding noisy environments with noise levels dominated by low to medium frequencies. These ear defenders feature liquid-and-foam filled sealing rings that provide an effective acoustic seal with low contact pressure, delivering comfort during extended use. The H520A version includes a hi‑visibility green headband and offers a high Single Number Rating (SNR) of 31 dB, making it suitable where both hearing protection and visibility are required; a dielectric (electrically insulated) headband option is also available.
Advantages

The liquid-and-foam sealing rings ensure a reliable acoustic seal at low contact pressure, reducing discomfort during long shifts. The hi‑vis green colour increases wearer visibility in high-risk environments. A dielectric headband variant is offered for electrically sensitive workplaces.

How to use
Place the ear muffs over the ears so the sealing rings fully enclose the ear and adjust the headband for an even, comfortable fit. Ensure hair, glasses or other obstructions do not break the seal. Position the muffs before entering noisy zones and check fit regularly during use. Replace cushions or sealing rings if they become worn or damaged to maintain protection.
Usage recommendations
Use the Optime II H520A in environments where noise is primarily low to medium frequency. For electrical work where dielectric properties are required, choose the electrically insulated headband version. Inspect the ear muffs before each use and follow local hearing protection regulations and employer safety procedures.
