10 Pairs Foam Earplugs 32 dB
Ten pairs of disposable foam earplugs provide a Noise Reduction Rating of 32 decibels. The uncorded design suits sleep, study or noisy work environments where hearing protection is needed. Bright colours make each pair easy to locate in a bag or drawer.
Thermals noise and power
Foam earplugs have no electrical components so they generate no heat, draw no power and produce no operating noise. The soft polyurethane material remains passive during use.
Pre-shaped foam and poly bags
Each pair is pre-shaped for quicker insertion and individually wrapped in a poly bag to keep the foam clean until use. The bell-shaped contour reduces pressure inside the ear canal during long wear. No software or additional accessories are included.

Questions about this item
How do I insert the polyurethane foam earplugs correctly?
Roll each earplug into a narrow crease-free cylinder with clean hands, pull your ear up and back, insert the plug and hold it until the foam expands to seal the canal.
When should I replace the disposable foam earplugs?
Discard each pair after a single use because the polyurethane foam degrades with moisture and earwax, reducing the 32 dB noise reduction and hygiene.
What limits the noise reduction during extended wear?
The 32 dB rating only holds while the slow-rebound foam maintains a complete seal; jaw movement or foam fatigue can break the seal and lower attenuation.
