Only the right earbud can't be charged. The earphones can be used if they can be charged (the left one can be charged, so it works normally). Since the right one can't be charged, would anyone who has a charger be interested? Consider the charging case as a bonus. I tried to disassemble it at the end, hoping to fix it, so it has many scratches.
