1, personal earphone plug is not pressed to the bottom;
2. The earphone plug or mobile phone jack is caused by virtual welding or poor contact;
3. Headphones are not compatible with personal mobile phones. Try a new headset or try to use it on other mobile phones.

Wrong idea
One of the misunderstandings: use a large volume for cooking headphones.
Some people think that the new headphones need to use a loud earphone pot, which can make the headphones enter the normal working state quickly and well, saving time.
This practice is actually a taboo in the use of headphones, because under normal circumstances, the diaphragm of new headphones is too rigid and the burning volume is too loud, which will make the vibration frequency exceed the bearing capacity of the new diaphragm and cause the diaphragm to be damaged. Use a moderate volume when cooking, which can be adjusted freely after a period of use.
Myth 2: The volume is too high when listening to headphones.
Listening to music at high volume for a long time has a very adverse effect on people's hearing, which will gradually lead to a serious decline in hearing and bring long-term damage to the ears. Long-term high volume will also make people's spirit excessively excited, resulting in physical and mental fatigue and mental fatigue.
And high volume has a great influence on the earphone diaphragm. Using high volume for a long time will cause sound distortion and even damage the diaphragm. Therefore, when listening to music, you should choose a moderate volume, neither too small, which will affect the aesthetic feeling of music, nor too big, which will hurt your ears. Moderate volume will also prolong the service life of headphones, which is one of the best maintenance methods.
