Sonis® 3 Helmet-Mounted Ear Defenders—engineered for maximum noise protection and designed with user comfort in mind. Boasting an industry-leading 36dB SNR, these ear defenders are your go-to solution for extreme noise environments, such as aircraft, quarrying, paper mills, and heavy engineering.
The Sonis® range, developed by JSP’s R&D team in collaboration with a top UK acoustic engineering facility, features a stylish traffic light colour-coding system for easy identification. The high-attenuation large cups, marked in red, are specifically designed to protect against noise levels ranging from 111-116 dB, ensuring unmatched protection.
Comfort is paramount with the Sonis® 3, thanks to the optimal cushion pressure provided by the carefully balanced force of the helmet adaptor and the generously sized cushion surface area. The adjustable steel arms allow users to tilt and position the cups for a perfect fit, ensuring even pressure distribution and long-lasting comfort.
With universal compatibility, these ear defenders easily integrate with JSP helmets and the Surefit™ visor system for comprehensive protection.
