Overview
A low profile cup on a wire headband, sized to sit under a safety helmet without the helmet riding up. Slim cups trade some attenuation for that fit, which is the honest trade.
Construction
- Low profile cups
- Wire headband
- Replaceable cushions
- Adjustable height
Where it fits
Sites where a helmet is worn at the same time, and confined areas where a full size cup catches on structure. State the noise level and whether a helmet is worn at order stage.
Lower profile, and lower attenuation is the price
Slim cups are specified for two situations: under a helmet, where a full-size cup fouls the harness, and in firing or working positions where the cup has to clear a stock or a shoulder. The trade is direct and worth stating, because less internal volume and thinner cushioning mean less attenuation, so a slim defender is chosen for compatibility rather than for maximum protection. Where the noise assessment calls for high attenuation, the bulky cup is the correct answer and the slim one is not.
What to confirm before ordering
- The attenuation your noise assessment requires: Use the figure your assessor worked from, not the highest number available.
- Whether it is worn with a helmet: That limits cup profile, and a fouled harness means the helmet sits wrong.
- Whether communication or level-dependent function is needed: It changes the product class entirely.
- Cushion replacement interval: Cushions are the wearable part; a hardened cushion leaks sound.
- Whether the wearer also wears spectacles: Temple arms break the seal, and that is not visible in a rating.
Compliance note
Ear defenders are rated by attenuation, and attenuation is measured on a test fixture with the cushions properly seated - which is not how they are worn at the end of a shift. The rated figure is therefore a ceiling: fit, hair, spectacle arms and a hard hat all reduce what reaches the ear. The construction and the attenuation the build is designed to are stated here; the test data for the article you order is supplied on request, and the noise assessment decides the level the task needs.

Samples and lead time
Sample pieces are supplied before a bulk order so your team can check fit, finish and marking on the actual article. Standard lead time is 2–4 weeks from order confirmation.
