Optime III Ear Defenders

Optime III has been developed for use in extremely noisy environments
The protection is based on new technology with a double casing that minimises resonance in the holder casing. This results in maximum high-frequency muffling, whilst giving easy-to-understand speech and 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 soft plastic foam for the best fit and low contact pressure
SNR: 35dB

Headband

Stainless sprung steel headband with individually sprung wires
Low, two-point fasteners on the cup
Wide, softly padded cushion over the top of the head makes the headband comfortable to wear even for long periods of time
