Ear Defenders
Ear defenders have been designed and developed for use in extremely noisy environments, airports, mines and marine engine rooms. The protection is based on new technology with a double casing that minimizes resonance in the holder casing. This results in maximum high frequency muffling while at the same time it's easy to understand speech and signals. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. Good inner space for ear.
