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. , SNR 35db<\/p>\n","protected":false},"excerpt":{"rendered":"
