Description JSP Sonis Compact Adjustable Helmet Mounted Ear Defenders 31dB SNR Developed in conjunction with a leading acoustic engineering research facility, the JSP Sonis range of ear defenders is stylishly colour-coded to help you decide what level of protection you need. Green is for low attenuation, Orange is for mid, and red is for high attenuation. When worn correctly, these headphones will reduce the sound level the ears are exposed to by 31 dB. This Sonis Compact helmet-mounted option offers ear protection for areas of substantial industrial noise, is suitable for use with the JSP EVO range of safety helmets, and features a low-profile design to integrate with other PPE. The ear cups can be rotated out of the way when not in use, keeping them secure on top of the helmet and helping prevent dirt and grime from getting into the ear cups. Easy to replace ear cushions and sound-deadening foam can be purchased to refresh your ear defenders when needed. Significantly extended the lifespan of the ear defenders. The ear cups have a full range of angle and height adjustments available, so you can be sure to get a perfect fit, seal, and pressure distribution on the ear. The adjustability and quality sealing rings work together with the moulded headband to make these ear defenders exceptionally comfortable and suitable for all-day use. Surefit universal accessory slots allow you to use JSP’s range of ear defenders and visors without compromising the performance or comfort of the helmet.
