This is a problem with headphones, and the solutions are as follows:

1. This problem is actually just a defect in the design of Huawei headphones. The original Huawei headphones are like this.

2. Pay attention to the control buttons. We can gently open them with our nails, and it looks like this.

3. Take out the small circuit board inside and turn it over, and you will find that there are four contacts on the back. The different wire control functions of the earphone are realized by combining and connecting these four contacts.

after the cover is fastened, the contacts are next to the metal wire on the back. After a period of use, the metal wire protective layer will be worn, and the contacts will be randomly combined and connected. At this time, we only need to cut a small piece of transparent tape with scissors and stick it on the circuit board to protect the contacts, and there will be no such situation.

whether the earphone has a fever or the speaker has a fever, the correct answer is the same: the volume closest to the actual listening is the most appropriate volume.

that is to say, when you listen to a symphony CD, what is the most appropriate volume? Imagine yourself sitting in a concert hall listening to a band performing this symphony, and imagine that you are not listening to a CD. Then, if you have enough live experience in the concert hall, you will know what the volume will be when you sit in the middle row of the concert hall. It is most appropriate to adjust the volume of HI-FI to such a large volume, which is closest to the real loudness of the scene. When listening at this volume, the distortion is the smallest, the reproduced music is the most realistic, and it is the easiest to produce good results.

by the same token, if you are listening to 1 JAZZ, imagine yourself sitting in a JAZZCLUB and the musicians on the stage are performing. Once, if you are familiar with the atmosphere and environment, you will know the real volume of the scene. It is most appropriate for you to adjust the volume of the system to the closest degree to reality.

the recording of a CD should contain the AMBIENCE (spatial reverberation) of the recording scene, so it is not difficult to tell whether it is a short-range recording, a medium-range recording or a long-range recording. So when you estimate the volume, you should take this "recording distance" into account. That is, if it is a close recording, imagine that you are sitting close to the performer; If it is a long-distance recording, imagine that you are sitting at a distance from the performer, and then estimate how much volume is needed.

so, to make your earphone system work at its best, remember to adjust the VOLUME to the most appropriate level, and don't twist the volume clockwise easily! If you are not familiar with the real volume of the scene, then find more opportunities to listen to the scene!
