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
