How to use PU foam earplugs
1)Many pu foram ear plug can not be cleaned, so keep your hand clean before use.
2) Take one ear plug and make it slim in your fingers.
3) Take your ear upwards and outwards (this is important), then insert the slim ear plug.
4) The slim ear plug will be relaxed in your ear tunnel (last 30 seconds), when you feel the ear plug is full of your ear tunnel. Then put down your hand.
How to identify the quality earplug
1) Low rebound effect
If it is too flexible, anti-noise earplug swelling suppression the canal skin, can cause ear swelling, earache and other discomfort. Flexibility can not be too small to close contact with the external ear canal, noise effect will be reduced. So we must observe ear plug and play back the return time, the better the quality.
2) Compliance
Flexibility directly affects the comfort level of wearing earplugs.
3) Surface texture
Some earplugs feel sticky, they will stick the ear canal skin when you worn on. We should avoid buying. The best way to identify is sticking two earplugs together closely then separating them. The separation time is the sooner the better.
