SONIS 3 HELMET MOUNTED EAR DEFENDER JSP SNR 36

PERFORMANCE
The Sonis® Mounted ear defender range peaks at an unbeaten 36 SNR. Our R&D team fine tune each component, using specialist design and test equipment to refine performance.

MULTI-DIRECTIONAL FIT
New side arms enable set and forget height adjustment for the perfect fit. The arms rotate independently 15° in each direction, maintaining a consistent seal around the ear.

ENHANCED COMFORT
Sonis cushions are made with frequency-optimised foam covered in a soft TPU skin. By rotating as the wearer moves, the side arms ensure even cushion pressure to enhance comfort.

ELECTRICALLY INSULATED
Non-conductive design with no exposed metal parts for safety in applications with electrical hazards. The mechanism’s steel spring is fully isolated to reduce conductivity risks.

HYGIENIC
The ear defenders are easy to wipe clean. 

CERTIFIED COMPATIBLE
Sonis® Mounted ear defenders are tested and certified with JSP helmets and EVOGuard® browguards, ensuring the correct level of hearing protection with each model. The side arms are designed to fit with a range of visor systems for combined protection.
