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 of 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.
3: The earphone is already full of charge.
When the earphone is fully charged, LED light does not turn on red.
4: The charging pin may not touch the charging pin.
The earphones sometimes do not sit properly on the charging electrodes due to the softness of the softshell. The softshell may conform to your ear and slightly change the shape during the use. Please find the location to charge properly by putting the convex of the earphone into the hole on the charging case. By pushing the earphone onto the spot, it should start charging (LED: Red) as well as putting back to the normal shape.
