Peltor Optime III - H540A

3M™ Peltor™ Optime™ III passive hearing protector H540A. Featuring a headband. Designed for use in extremely noisy environments, especially those dominated by low-frequency sounds. Protection is based on a double-shell technology that minimizes resonance in the outer shell, resulting in maximum high-frequency attenuation. An acoustic connection between the inner cavity and the cavity between the shells provides maximum low-frequency attenuation.

• The sealing rings are wide and filled with soft plastic foam to provide the best possible fit and low contact pressure.
• Optime™ hearing protectors guarantee effective protection and maximum comfort for the user.
• Soft, wide sealing rings help reduce pressure around the ears and improve comfort and durability.
• A hygiene kit is available as an accessory.
