The Sonis® range has been stylishly designed with a traffic light colour code for easy identification - from the green Sonis® 1 for low level noise moving through to the red Sonis® 3 for use in more extreme environments. Materials have been chosen for both performance and comfort for extended periods of use. Designed by the JSP R&D team. Working with a leading UK acoustic engineering research facility they have developed an ear defender range that peaks at an unbeaten 37dB SNR. Cup size and weight, along with frequency optimised foam sections, ensure performance is guaranteed, no matter what your hearing protection requirements are.
