| 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 |
| Attenuation rating SNR 35dB, High Frequency = 40dB, Medium Frequency = 32dB, Low Frequency = 23dB |
| Effective protection and best comfort are the hallmarks of Optime III. SNR = 35dB |

| Soft wide cushions helps reduce pressure around the ears and improves comfort and wearablity |
| The protection is based on a technology with a double casing that minimises resonance in the holder casing |
| 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 |
| This results in maximum high-frequency muffling while at the same time its still easy to understand speech and signals |
