Wide spread of attenuation
07 February 2017
JSP’s R&D team has designed a new range of Sonis Ear Defenders which are said to peak at an unbeaten SNR of 37.

Kitemarked and meeting EN352-1, Sonis Ear Defenders offer a wide spread of attenuation with SNR values between 27 and 37 meaning that selecting the right model to match the wearers requirements is straightforward.
The stylish range has been designed with a traffic light colour code for easy identification and selection. The range moves from the green Sonis 1 for low level noise to the yellow Sonis 2 and the orange Sonis Compact for substantial Industrial noise through to the market leading SNR of 37 for the red Sonis 3 to protect against extreme industrial noise.
The over moulded headband has a built in comfort area with ventilation to help reduce heat build- up. The headband force and the sealing ring surface area work together to provide optimum cushion pressure and therefore comfort.
