Portwest HV Extreme Ear Defenders High Clip-On Metal Free

Maximum helmet-mounted hearing protection for high-noise environments — with no metal components in sight. The Portwest PW05 HV Extreme High Clip-On Ear Defenders deliver superior noise attenuation at SNR 28dB alongside 100% metal free construction, making them the highest-performing option in the HV Extreme clip-on range for applications demanding both strong hearing protection and non-conductive PPE.

Built with fully plastic arms throughout, the PW05 is engineered for safe use in electrical trades, utilities, high-voltage environments, and any worksite where metal components in PPE present an unacceptable risk. Designed specifically for Portwest Endurance and Height Endurance helmets, they clip on quickly and securely, forming part of a complete, integrated head protection system without the need for tools or additional hardware. The adjustable dual pin system offers multiple positioning options to achieve a stable, personalised fit across different head shapes and helmet sizes, and the repositionable ear cups can be swung aside between noise hazard areas — keeping the defenders in place on the helmet without interrupting workflow.

At SNR 28dB and certified to EN 352-3, the PW05 is the right choice for consistently loud working environments — heavy industry, demolition, power generation, heavy construction, and high-output manufacturing — where robust, reliable attenuation is non-negotiable. Colour-coded cups provide instant visual identification of the attenuation level, supporting safe selection and compliance across the full team.

Supplied in a retail presentation box and individually packed for vending machine compatibility.

Which helmets are the Portwest PW05 ear defenders compatible with? The PW05 is designed exclusively for use with Portwest Endurance and Height Endurance helmets. They are a clip-on product and require a compatible helmet — they are not designed for standalone headband use.

How does the PW05 differ from the PW03 and PW04? All three products are 100% metal free clip-on ear defenders from the HV Extreme range, compatible with the same Portwest helmets. The distinction is attenuation level. The PW03 offers low attenuation at SNR 23dB for environments where over-protection is a concern. The PW04 provides medium attenuation at SNR 26dB for moderately harmful noise. The PW05 delivers high attenuation at SNR 28dB, making it the appropriate choice for the loudest and most hazardous noise environments in the range.

What noise environments require SNR 28dB high attenuation hearing protection? SNR 28dB high attenuation is suited to heavy industry, demolition, power generation, large-scale manufacturing, and other consistently loud working environments where prolonged exposure to harmful noise levels is a significant risk. It provides superior noise reduction while remaining part of a fully integrated helmet-based PPE system.

Why is metal free hearing protection important on certain worksites? On sites involving electrical installations, high-voltage systems, live conductors, or other conductive hazards, metal components in PPE carry a genuine risk of electrical conductivity. The PW05 is constructed entirely without metal, meeting the requirements of risk assessments that specify non-conductive or metal free PPE for head protection systems.

Can the PW05 ear defenders be repositioned when not in use? Yes. The ear cups can be swung away from the ears when hearing protection is not immediately required, without detaching the defenders from the helmet. This is particularly useful for workers who move frequently between noisy and quieter areas throughout the working day.

Are the PW05 ear defenders compatible with vending machines and retail display? Yes. The PW05 is individually packed for full vending machine compatibility and is also supplied in a retail presentation box suitable for trade counter and point-of-sale display.
