Misunderstanding

One of the misunderstandings: Use a loud volume when cooking headphones

Some people think that new headphones need to use a loud volume cooker, which can make the headphones work well and quickly, and save time.

In fact, it is a big taboo to use headphones, because under normal circumstances, the diaphragm of new headphones is too rigid, and the high-volume pot will make the vibration frequency exceed the bearing capacity of the new diaphragm, causing the diaphragm to be damaged. You should use a moderate volume when cooking, and you can adjust it at will after using it for a while.

Myth 2: Loud volume when listening to headphones

Listening to a concert at a high volume for a long time will have a very adverse impact on people's hearing, which will gradually lead to a serious decline in hearing and long-term damage to their ears. Loud volume for a long time will also make people's spirits excessively high, which will cause physical and mental fatigue.

Moreover, loud volume has a great influence on the earphone diaphragm. Long-term use of loud volume will distort the sound effect and even damage the diaphragm. Therefore, when listening to music, you should choose a moderate volume, neither too small to affect the beauty of music, nor too big to hurt your ears. Moderate volume will also prolong the service life of headphones, which is one of the best maintenance methods.
