What should I do if my boyfriend's earphone never leaves his ear?

Everyone will have their own likes and hobbies, but if this is a bad behavior, it will bring harm to the body.

Your boyfriend is an adult, not a child. So you can't force him to correct the bad habit of ear phones. But if you don't change it, it will bring serious consequences to your ears, such as hearing loss or deafness.

I suggest you communicate with him well, be emotional and rational. People are human beings, as long as they persuade each other in good faith, the average person can listen. If you don't listen to such kind words and repent, such a man will have no sense of responsibility and responsibility.

You can't give the life you want at all, so you need to reposition your relationship.
