Our HV extreme premium colour coded ear defenders offer helmet-mounted hearing protection that ensures superior noise attenuation. The ear defenders are specially designed to be used with Portwest Endurance and Height Endurance helmets, and can be easily attached to the helmets for a secure and comfortable fit. With medium attenuation performance, our ear defenders are perfect for environments where noise levels can be harmful. The colour-coded cups make it easy to identify the correct attenuation level, ensuring maximum protection.
