Headphones are a very common electronic digital product in our lives, and they also bring us great convenience. The most commonly used function of migrant workers is the call function of the earphone. After the sound signal is collected from the earphone microphone hole, also called the MIC hole, it is converted into an electrical signal. MIC is a word abbreviated from Microphone, which is we often call microphone.



When we use earphones, most of them are outdoors or in non dry environments, so the air leakage treatment of earphone holes are very important. If it is not handled well, it will affect the user's experience.
