1. Choose the appropriate earplug size: You can try earplugs of different sizes to find the one that suits you best.

2, adjust the way of wearing: you can try to change the way of wearing, such as turning the earplug slightly, or gently pressing with your fingers to make it better fit the ear canal.

3, adapt to the ear canal: the ear canal is sensitive, you can try the smaller earplugs first, and then gradually adapt to the larger earplugs.

4, pay attention to cleaning: In-ear headphones are easy to breed bacteria, clean regularly to avoid dirt accumulation caused by falling headphones.
