When you are not able to charge the earphones, please try the followings.
1: Take off the protection sheet from the earphones
When VIE FIT is coming out the factory, we put the protection sheet on to the earphones charging pin in order to avoid the battery damage in the warehouse. Please take off the sheet to start charging.
2: Check if the charging case still has the battery left
If the earphones are not charging in the case, the charging case's battery may be empty. Please check the battery counter LED by pushing the button beside.
