Problems solved by technology

[0002] Earmuffs are usually used to isolate harsh sounds. Traditional earmuffs are usually shells with simple structures, and the noise isolation effect is also poor.
Some earmuffs are also equipped with an in-hood speaker in the earmuff shell, through which the audio signal of an external audio device can be played, but only the earmuff shell is responsible for noise isolation, and the noise isolation effect is poor, which will affect the listening sound quality
