Portwest HV Extreme Ear Defenders - Grey

Their main purpose is to protect the wearer's hearing from harmful noise levels in environments with high sound pollution.

The colour-coded cups indicate different attenuation levels. Refer to the product documentation or manufacturer's guide for specific details on which colour corresponds to the required noise reduction for your environment.

The ear defenders are designed to be compatible with most standard safety headgear, but fit may vary. Ensure there is enough clearance for a comfortable and secure fit without compromising the seal of either item.

With proper care and regular inspection, the ear defenders are designed for long-term use. However, components like the ear cushions may wear over time and should be replaced if damaged or degraded.

Yes, these ear defenders are CE certified and designed to provide excellent attenuation rates suitable for various industrial noise environments.

'HV' typically stands for High Visibility, referring to the reflective trim that enhances the wearer's visibility.

Gently wipe the reflective trim with a damp cloth. Avoid harsh chemicals or abrasive materials that could damage the reflective surface.

Adjust the dual pin system to a different position. Ensure the headband is correctly positioned on your head, not too high or too low.

Ensure the headband is adjusted to the correct tension – not too tight. Clean the padded headband as per care instructions. Allow for breaks from wearing the ear defenders if possible.

Refer to the product manual or Portwest website for a guide to colour-coded attenuation levels. Clean the cups gently if dirt is obscuring the colour.
