The Sonis® 1 Adjustable Ear Defenders provide reliable hearing protection with a 27dB SNR rating, making them ideal for moderate noise environments. Designed by the JSP R&D team in collaboration with leading UK acoustic engineers, the Sonis® range combines proven noise attenuation with long-lasting comfort and durability.

Featuring an adjustable steel headband, each ear cup can be tilted and positioned to achieve an optimal, personalised fit. The headband is overmoulded with flexible TPE and incorporates built-in ventilation to improve comfort during extended periods of use. Carefully selected cushion materials create an effective seal while evenly distributing pressure.

Constructed with impact-resistant ABS ear cups and robust acetal pivot arms, the Sonis® 1 is built to withstand demanding working conditions. Easy to wipe clean and compatible with optional hygiene kits, these ear defenders are suitable for workshops, printing works, landscaping, leisure activities, and other moderate industrial noise applications.
