[How to identify the quality of earplugs]]

1. Slow rebound effect: the elasticity is too large, and the skin of the external auditory canal is pressed when it expands ear plug, which can cause discomfort such as ear swelling and ear pain; If the elasticity is too small, it cannot be in close contact with the external auditory canal, and the sound insulation effect is reduced. Therefore, the rebound speed of earplugs must be observed. The longer the rebound time, the better the quality.

2. Softness: softness directly affects the comfort level of earplugs

3. Surface texture: some earplugs are sticky to the touch, and they will stick to meatus acusticus of the skin when worn in the ears. Avoid buying them as much as possible. The best way to identify is to stick the two earplugs tightly together and then separate them. The sooner they are separated, the better.

【 precautions]]

1. Due to the rapid recovery time of the earplugs, users should make sure that the earplugs are rubbed fine before they are inserted into the ears, otherwise the best effect cannot be achieved;

2. Remember to pull the ear up and outward before inserting it into the ear. Only after the earplug expands can it exert its effect;

3. Keep your hands clean during operation;

4. Take it out slightly, slowly, and rotate to pull it out. Don't push too hard, and don't just pull the rope.
