H540B PELTOR OPTIME III NECKBAND BLACK

• Optime III is a super-muff, and has been developed for use in extremely noisy environments. • The protection is based on a technology with a double casing that minimises resonance in the holder casing. This results in maximum high-frequency muffling, while at the same time its still easy to understand speech and signals. • An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling. • The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. • Effective protection and best comfort are the hallmarks of Optime III
