What are the hazards of soundproof earmuffs?

Acoustic earmuffs will have a little effect on the ears, mainly for these reasons:

(1) If the earmuffs are left in a humid environment for a long time, many bacteria will breed, which will cause otitis media.

(2) When using sound-proof earmuffs, it is best to clean the earwax in advance. If there is too much earwax, it may cause slight tinnitus, pain or bacterial infection when wearing it.

(3) In another case, we can look at the quality of sound-proof earmuffs. If you have some inferior earmuffs, it may have a bad effect on your ears. You can choose some high-quality sound-proof earmuffs, mainly depending on what materials they are made of.
