The Sonis® 1 Helmet Mounted Ear Defenders (26dB SNR) offer reliable hearing protection with outstanding comfort and compatibility across a wide range of industrial and environmental noise applications. Developed by JSP’s R&D team in collaboration with a leading UK acoustic engineering facility, the Sonis® range delivers precision acoustic performance backed by rigorous testing and innovation.
These helmet-mounted defenders are designed for easy attachment to JSP safety helmets, integrating seamlessly with the Surefit™ visor system for full head and face protection. The 26dB SNR rating makes them ideal for environments with moderate industrial noise, providing balanced attenuation without over-isolation.
Constructed with adjustable steel arms and soft, replaceable sealing rings, the Sonis® 1 ensures a secure and comfortable fit for extended wear. The traffic-light colour code system enables quick identification of protection levels — green indicating low to medium noise attenuation.
Lightweight, durable, and ergonomically balanced, the Sonis® 1 is a dependable choice for workshops, landscaping, printing works, and general industrial tasks.
