JSP Sonis 3 Adjustable Overhead Ear Defenders - 37dB SNR

Descriptions

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.
