What you get

This pack contains 50 pairs of disposable foam earplugs in a safety-sealed jar. Each pair carries a Noise Reduction Rating of 33 decibels and a matching Single Number Rating. The beige polyurethane foam is made in the USA and expands slowly for a low-pressure fit.

Who these suit and who they don't

Sleepers, students, concert-goers, motorcyclists and anyone needing high attenuation for occasional use will find them effective. They are not for users who need reusable plugs, a corded design, electronic noise cancellation or a smaller quantity than 50 pairs.

Behaviour during extended wear

The slow-release foam maintains its seal over long periods without increasing pressure in the ear canal. Because the plugs are disposable, hygiene stays consistent across multiple sessions and there is no degradation from cleaning or storage.

Questions about this item

Do these earplugs need any power source or device to function?

No, they operate without batteries or external power — just compress the polyurethane foam and insert for immediate noise reduction.

Can I use them with my existing hearing protection headband or earmuffs?

Yes, the low-profile beige foam pairs fit under most over-the-ear muffs or headbands without breaking the seal of either device.

How do I confirm each pair is sealing correctly after insertion?

Hold the plug in place until the slow-release foam fully expands; a proper seal feels snug and reduces ambient sound by the rated 33 decibels.
