Quick Overview

These NRR 33 disposable foam earplugs provide high-level hearing protection in hazardous noise environments like shooting ranges, construction sites, and industrial workshops. Their primary function is to prevent permanent Noise-Induced Hearing Loss (NIHL) during short or extended exposure to high-decibel sounds.

Field Application Steps

With clean hands, roll the earplug into a tight, crease-free cylinder.
With the opposite hand, reach over your head and pull the top of your ear up and back to straighten the ear canal.
Insert the compressed plug well into the ear canal until it is nearly flush with the outer ear.
Hold the plug in place with a fingertip for 30-60 seconds to allow it to fully expand.
Confirm a proper seal by observing a significant drop in ambient noise.
Discard the pair after a single use; do not attempt to clean or reuse.
