The Sonis® 3 Helmet Mounted Ear Defenders deliver outstanding hearing protection with an industry-leading attenuation rating of 36dB SNR, making them ideal for extremely noisy environments. Designed by JSP’s R&D team in collaboration with leading UK acoustic engineers, they offer exceptional high-frequency noise reduction through optimised cup size, weight, and foam technology.
Built for comfort during extended wear, the ear defenders feature carefully selected cushion materials that create an effective seal while evenly distributing pressure. Adjustable steel arms allow each ear cup to be tilted and positioned for a precise, personalised fit, maintaining consistent performance across a wide temperature range.
Manufactured with impact-resistant ABS ear cups and robust acetal pivot arms, the Sonis® 3 is designed to withstand heavy wear in harsh industrial environments. The ear defenders are easy to wipe clean, with optional hygiene kits available for replacing cushions and foam inserts. Certified for compatibility with JSP helmets and the EVOGuard® browguard, they are ideal for applications such as heavy engineering, quarrying, aircraft operations, paper mills, and other extreme noise settings.
