High visibility ear defenders with SNR 28dB protection, PU padded headband and reflective trim. Dual pin adjustable cups for all head sizes. CE certified to EN 352-1. Ideal for medium attenuation environments.
The Extreme Ear Defenders HV are a solid bit of kit for anyone who spends serious time around noisy machinery, power tools or busy construction sites. Rated SNR 28dB and certified to EN 352-1, these sit comfortably in the medium attenuation category — meaning they take the edge off harmful noise without making you completely deaf to what’s going on around you. That balance matters more than people give it credit for.
The headband is padded with PU foam, which makes a genuine difference over a long shift. Plenty of ear defenders are fine for the first hour and then slowly become something you’d rather leave in the van. These are built with extended wear in mind, and the soft padding keeps pressure off the skull without compromising the seal.
What Makes These Extreme Ear Defenders Stand Out
The dual pin adjustable cup system is worth mentioning. It gives you multiple positioning options so you can dial in the fit rather than just pulling the arms to roughly the right length and hoping for the best. Useful when you’re sharing a pair across a crew, or when you’ve got an unusually large or small head — no judgement either way.
The HV colour coding is a practical touch. On a busy site where multiple workers are wearing different levels of PPE, being able to identify protection levels at a glance saves time and avoids the awkward conversation about whether someone’s got the right gear on. The reflective trim on the headband adds genuine low-light visibility, which is more useful than it might sound if you’re working in warehouses, plant rooms, or during the shorter winter days.
These are CE certified to CAT III, which puts them in the highest category of PPE under EU and UK legislation — that’s the category reserved for serious risk, and it tells you something about how these have been tested. They come individually packed, making them compatible with vending machine dispensing systems and straightforward for site stores management.
Pro Tip: When fitting ear defenders, pull the top of the ear upward and outward before seating the cup — this helps the cushion form a proper acoustic seal around the ear, which directly affects how much of that 28dB attenuation you actually get in practice.
These ear defenders are used across construction, manufacturing, groundworks, demolition, and any environment where sustained noise exposure is a concern. Common applications include operating or working near generators, concrete breakers, angle grinders, circular saws, compressors and plant machinery. They are also widely used in warehousing and logistics environments where forklift traffic and loading equipment create consistent background noise.
The high visibility headband and reflective trim make these particularly well suited to outdoor work, roadside jobs, and any setting where worker visibility matters as much as hearing protection. They are a practical choice for site managers issuing PPE from stores or vending systems, given the individual packaging.

Key Specifications
Standard: EN 352-1
SNR: 28dB
Certification: CE CAT III
Materials: ABS, Mono PU, Polyoxymethylene, Foam
Headband: Reflective PU padded
Adjustment: Dual pin system
Not suitable for: Not suitable for environments requiring high attenuation protection above SNR 28dB, such as close proximity to jet engines, explosive operations or other extreme noise sources. For those applications, a higher SNR rated defender should be selected.
These ear defenders are an over-the-head fit. Extend the arms to the appropriate length using the dual pin adjustment, seat each cup firmly over the ear, and check the cushion is forming a full seal around the ear canal. Any gap in the seal reduces attenuation significantly, so take a moment to get the fit right rather than just plonking them on.
The reflective trim requires no maintenance, but keep the cushions clean and check them periodically for cracking or compression. Degraded cushions affect seal quality and should be replaced when worn.
Adjust the headband arms using the dual pin system to suit your head size before first use
Pull the top of the ear upward and outward, then seat the cup fully over the ear
Check both cups are sealing evenly against the head with no gaps at the cushion edge
Confirm the headband sits comfortably on the crown of the head without excessive pressure
Inspect the ear cushions regularly for signs of wear, cracking or permanent compression
Clean cushions with a damp cloth and mild detergent, avoiding solvents that can degrade the foam
What does SNR 28dB mean in practice?
SNR stands for Single Number Rating, and 28dB is the average noise reduction you can expect when the defenders are fitted correctly. In real terms, it means if you're working in an environment with 100dB of noise, your exposure drops to around 72dB. That puts you comfortably within safe exposure limits for a standard working day. Getting the seal right when fitting them is what makes the difference between getting that full 28dB or something considerably less.
Are these suitable for issuing through a PPE vending machine?
Yes, they are individually packed specifically with vending machine compatibility in mind. The retail box packaging also makes them straightforward for site stores and PPE dispensing systems. The colour coded cups help workers and supervisors quickly identify the protection level in use.
Constructed from ABS shell cups, Polyoxymethylene adjusters and Mono PU foam cushioning, these ear defenders are built to the EN 352-1 standard for passive hearing protectors. CE certified under Category III, the highest classification for PPE, reflecting their use in environments posing serious or irreversible hearing risk. The reflective material on the headband meets general visibility requirements for PPE used in low-light working conditions.
