Portwest HV Extreme Ear Defenders Low Clip-On Metal Free

Certified helmet-mounted hearing protection built for environments where metal simply isn't an option. The Portwest PW03 HV Extreme Low Clip-On Ear Defenders bring the trusted performance of the premium HV Extreme family to applications requiring fully non-conductive PPE — making them the go-to choice for electrical work, utility maintenance, and any setting where metal-free equipment is a safety requirement.

Engineered with plastic arms in place of metal components, the PW03 is 100% metal free without compromising on protection or practicality. Designed to clip directly onto Portwest Endurance and Height Endurance helmets, they attach quickly and securely, integrating seamlessly into a complete head protection system. An adjustable dual pin system provides multiple positioning options to ensure a comfortable and stable fit across different head shapes and sizes, while the ear defenders can be easily repositioned away from the ears when not in active use — avoiding the need to remove them entirely in fluctuating noise environments.

With an SNR rating of 23dB certified to EN 352-3, the PW03 is specifically calibrated for lower attenuation performance, making it the right choice where over-protection is a concern — such as environments where workers must remain aware of verbal communication or audible warnings while still being shielded from harmful noise levels.

Colour-coded cups make it straightforward to identify the correct attenuation level at a glance, supporting compliance across teams and worksite safety systems. Supplied in a retail presentation box and individually packed for vending machine compatibility.

Which helmets are the Portwest PW03 ear defenders compatible with? The PW03 is designed to clip onto Portwest Endurance and Height Endurance helmets. It is not intended for use as a standalone headband ear defender and should always be used in combination with a compatible helmet.

Why are metal free ear defenders important? In environments involving electrical hazards, live systems, or work near conductive materials, metal components in PPE can pose a significant safety risk. The PW03 uses fully plastic arms and non-conductive materials throughout, making it safe for use in electrical installation, utility maintenance, and similar applications where non-conductive PPE is specified.

What does SNR 23dB mean and when is low attenuation the right choice? SNR 23dB is a lower attenuation rating, intentionally designed to reduce harmful noise while still allowing the wearer to hear speech, warnings, and environmental sounds clearly. Over-protection — where hearing protection blocks too much sound — can actually be dangerous in some work environments. The PW03 is the appropriate choice where workers need protection without being isolated from their surroundings.

How does the dual pin adjustment system work on the PW03? The adjustable dual pin system allows the ear defenders to be positioned at multiple points along the helmet attachment, enabling wearers to optimise the fit and seal for their individual head shape and helmet size, ensuring consistent and effective hearing protection throughout the working day.

Can the PW03 ear defenders be moved out of the way when not in use? Yes. The PW03 can be comfortably repositioned away from the ears when hearing protection is not required, without needing to remove them from the helmet entirely. This makes them a practical choice for workers who move in and out of noisy areas frequently.

Are the PW03 ear defenders suitable for vending machines? Yes. The PW03 is individually packed, making it fully compatible with PPE vending machines as well as retail display formats.
