• The slim ear plug will expand in your ear canal (last 30 seconds). When you feel that the ear plug has swelled to the fullest in your ear canal, put down your hand.

Slow rebound
If the polyurethane earplug is too flexible, it will have swelling suppression on the canal skin, and can cause ear swelling, earache and other discomfort. But it also cannot be too inflexible to close contact with the external ear canal, otherwise noise reduction effect will be weakened. So we must observe ear plug and play back the return time, the better the quality.

Compliance
Flexibility directly affects the comfort level of wearing earplugs.

Surface texture
Some polyurethane earplugs feel sticky, and they will stick the ear canal skin when you wear them. We should avoid buying such earplugs. The best way to identify sticky earplugs is sticking two earplugs together closely and then separating them. The separation time is supposed to be the shorter the better.
