| An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling |
| and has been developed for use in extremely noisy environments |
| Approved to EN352-1 for overhead wear |
| Broad sealing rings filled with soft plastic foam |
| Colour: Red and Black |
| Comfortable fit and low contact pressure |
| Effective protection and best comfort are the hallmarks of Optime III |
| High performance ear defenders for extremely noisy environments |
| Optime III is a super-muff |
| SNR 35db |
| 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 |
| The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure |
| while at the same time its still easy to understand speech and signals |
