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.
Force the helmet adaptor applies and the cushion surface area work together to provide optimum cushion pressure and comfort
Adjustable steel arms facilitate even distribution of pressure the wearer can tilt and adjust the position of the earcup for optimum comfort and fit
Cushion materials have been carefully selected to generate a perfect seal
Sealing rings are easy to replace
Hygiene kits are available for each model
36dB SNR
Attenuation: H = 37, M = 35, L = 26
