Now many students use earphones to listen to music and learn English. Because of your ear problems and poor memory, I'm afraid you spend too much time listening with headphones. In fact, listening to music while you are in class may distract your attention from your study.

Excessive use of headphones can damage your hearing. There are many ways to enjoy music and learn English. For example, a recorder or radio may be a good choice.

But if you really need to use headphones, you should rest your ears for at least 10 minutes every hour, but Don't exceed a few hours a day, I hope things will get better soon.
