The Sonis® 1 Adjustable Ear Defenders provide dependable hearing protection with a 27dB SNR rating, making them ideal for moderate noise environments. Part of the Sonis® range developed by the JSP R&D team alongside leading UK acoustic engineers, they combine effective noise reduction with long-lasting comfort and durability.

The adjustable steel headband allows each ear cup to be tilted and positioned for an optimal, personalised fit, while maintaining performance across a wide temperature range. Overmoulded in flexible TPE with built-in ventilation, the headband works with carefully selected cushion materials to deliver consistent pressure and comfort during extended use.

Constructed with impact-resistant ABS ear cups and robust acetal pivot arms, the Sonis® 1 is built to withstand heavy wear in demanding environments. 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.
