I don't think you can get that repaired. It is extremely hard; it is mainly replaced. We sales them what brand you are looking for?
It may be more feasible cost wise to replace your earbuds. If you have some name brand earbuds, such as Airpods, I would recommend that you check with the manufacturer to see if a repair/replace option is available. Thank you for your interest in All About Technology, Home of the $200 Computer!
