Description

How can it do hearing protection？In areas where sound is severe, such as airport range construction sites, even noise levels above 125 dB for a short period of time can cause permanent hearing loss. Our 34dB NRR earmuffs protect your hearing by reducing noise to a safe level.Why the ear muffs are too tight?This size fits 95% of people. If too much pressure is applied, it is recommended that the earmuffs be placed on a box (or other object) to stretch the headband. This will make it looser to wear and therefore more comfortable.
