Solution

1. Make sure the battery is fully charged.

   The indicator lights up in orange when charging starts, and after charging is complete, the indicator will turn off.

   • If the headphones can't start charging, refer to the following depending on the situation:

   The indicator repeatedly flashes twice in orange with an interval of about 1 second while charging the headphones or charging case

   
   The abnormal temperature may prevent the charging. Leave the charging case in a place with an ambient temperature between the values listed below, and try charging again. Efficient charging may not be possible beyond the range.

   • LinkBuds Clip: 5 °C to 35 °C (41 °F to 95 °F)
