Provide extreme anti-noise efficiency. The protection is based on the technical approach connected with a double casing that minimizes resonance in the holder casing and provides maximum high-frequency muffling, while at the same time it's still easy to understand speech and warning signals. An acoustic connection between the inner volume and the volume between the casings provides maximum low-frequency muffling. 
The sealing rings are broad and filled with liquid and foam which results in increased comfort and lowered contact pressure. 

Recommended industries: military airfields, civil airports, engine-rooms of major vessels, mining and construction.
