Portwest PS47 Endurance HV Hi-Vis Clip-On Ear Defenders (Orange) - PS55 Helmet Attachment

Product Description

The Portwest PS47 Endurance HV Clip-On Ear Defenders are premium, high-visibility hearing protectors specifically engineered for seamless integration with safety helmets, including the popular Portwest PS55 Endurance Helmet series. Designed for professionals working in medium-to-high noise risk environments, these clip-on earmuffs deliver certified auditory defense without compromising on head protection, visibility, or comfort.

Featuring a universal 30mm slot connection, the PS47ORR instantly and securely clips into the side channels of your hard hat. The high-visibility orange design maximizes worker safety during daylight hours and low-light transitions, making them an essential addition for construction, rail, demolition, and roadside maintenance crews. Equipped with an adjustable dual-pin system, these ear defenders allow for tailored, multi-position adjustments to guarantee a perfect face-to-gasket seal.

When absolute quiet isn't required, the innovative "stand-off" design allows the ear cups to be clicked outward and parked away from the ears while remaining securely attached to the helmet—offering unparalleled convenience for intermittent noise protection throughout the working day.
