The earwax in the ears has nothing to do with the sound quality of the headphones, but it will affect your own hearing. Sometimes if there is too much earwax, you will feel that the sound quality of the headphones has changed and it is no longer as good as before. It feels like the headphones The sound became a little softer. This happened to me once. Later I found out that there was something wrong with my ears, so I went to the hospital for a checkup. The doctor said that I had too much earwax and helped me clean my ears. At that time, I suddenly felt like the whole outside world Everything is clear and transparent. It is not very good to listen to the stereo at this time. If there is too much earwax, you can go to the hospital to clean it. I have only had it cleaned once, and it has been many years.
