Instructions for use:

2, the other hand is going to plug the ear up and out of the lift (this is very important) and hold, and then rub the fine round ear plug towards the ear, insert it;

3. Hold the earplug with your hand until the earplug completely expands in the ear (about 20 or 30 seconds).

How to distinguish between good and bad earplugs

1. Slow rebound effect

The elasticity is too large, and the anti-noise earplugs compress the skin of the external ear canal when they expand, which can cause ear distension, ear pain and other discomfort; If the elasticity is too small, it can not be in close contact with the external ear canal, and the sound insulation effect is reduced. Therefore, it is necessary to observe the rebound speed of the earplug, and the longer the rebound time, the better the quality.

2. Softness

The softness directly affects the comfort of wearing earplugs

3. Surface texture

Some earplugs feel sticky and stick to the skin of the ear canal when worn in the ear, and should be avoided as much as possible. The way to identify them is to glue the two earplugs together tightly and then separate them, and see how soon they separate, the better.
