These helmet-mounted ear defenders from the HV Extreme family are for work where high attenuation against harmful noise is needed. They clip onto Portwest Endurance and Height Endurance helmets, so your hearing and head protection work as one system.
With plastic arms and a fully metal-free build, they suit sites where non-conductive PPE is required. Colour coded cups make it quick to identify the correct attenuation level at a glance.
