Key specifications

• Form factor: ear-insert, single-use

How to use

Before use, inspect the earplug packaging to confirm the corded or uncorded configuration and to ensure the product is undamaged and within its intended storage life. To insert, roll the earplug between clean fingers to compress it, reach over the head with the opposite hand and gently pull the outer ear upward and backward to straighten the ear canal, then insert the compressed plug and hold it until it expands to form a seal. Remove the plug slowly and gently by twisting while pulling outward to avoid ear discomfort. Dispose of the earplug after a single use according to local waste guidelines.

Usage recommendations

Use this earplug where temporary or disposable hearing protection is appropriate. For continuous or high-noise exposures, consider higher-grade or reusable hearing protectors and consult workplace hearing protection guidelines. Ensure the earplug forms an effective seal in the ear canal for proper attenuation; if fit or comfort is inadequate, choose an alternative size or type of hearing protection.
