The Sonis® 3 Adjustable Ear Defenders deliver exceptional hearing protection with an industry-leading attenuation rating of 37dB SNR, making them ideal for extremely noisy environments. Developed by the JSP R&D team in collaboration with leading UK acoustic engineering specialists, the Sonis® range is engineered to maximise high-frequency noise reduction through optimised cup size, weight, and foam technology.
Designed for comfort during prolonged use, the adjustable steel headband allows each ear cup to be tilted and positioned for a precise, personalised fit while maintaining consistent performance across a wide temperature range. The headband is overmoulded with flexible TPE and includes built-in ventilation to help manage heat and pressure.
Constructed with impact-resistant ABS ear cups and robust acetal pivot arms, the Sonis® 3 is built to withstand harsh industrial conditions. Easy to wipe clean and compatible with optional hygiene kits, these ear defenders are suitable for demanding applications such as aircraft operations, quarrying, paper mills, heavy engineering, and other extreme industrial noise environments.
