Can the earphone be repaired?

I admit that upstairs is much richer than me. Headphones are not expensive There is a 20w joke, but you say it's not expensive. Even what I heard is cheaper, more than 300 yuan. Buy if you have money! If you have the money to buy a big Olympics, you can treat it as nonsense. If you don't have money and still think headphones are cheap, please ask Baidu to comment again.
