Protos Integral ear defenders are exceptionally comfortable to wear and slot simply and quickly into position inside the Protos helmet shell, providing noise reduction of SNR 26dB. The contact pressure and ear position are adjustable so as to obtain the perfect fit for each individual wearer. The contact pressure can be adjusted by increasing or decreasing the pressure via the red dial positioned on the inner side of the ear defender whilst the ear cups slide up and down on the bracket arm to obtain the perfect fit over the ear. Protos Integral ear defenders are positioned on the inside of the helmet shell, thereby preventing any snagging on the outside and when the ear defenders are not required for use, they simply park up inside the shell. This keeps the ear defenders dry and allows air to circulate when they are not in use. Supplied as a complete set, one left and one right, with hearing protection absorption and support pads, ready for use. Replacement hygiene kits are available and are simply installed. Certified to standard EN352-3 Recommendation to maintain the noise absorption values: Absorption Inserts should be replaced every 2-3 years and the outer Support Pads should be replaced every six months for daily use.
