Important: When charging the earbuds, charging indicators on the charging dock will flash every second. If LEDs are not flashing, please go to another section "Defective charging dock".
If your both earbuds cannot charge, please take the following troubleshooting steps:
1) clean the charging pins and contacts on the charging dock when it is turned OFF: take a clean slightly damp washcloth and wipe them down. (We recommend using clear water, or detergent for electronics).
2) try charging the case with another micro-USB cable, another power source/another adaptor (if any).
3) try changing the earbuds places in the dock to see if the earbuds will charge through the slot for the right earbud and vice versa.
4) clean the POWER buttons on both earbuds (according to 1st step).
Note 1: High humidity and extreme temperatures can cause the deformation of the device and affect the battery performance and the dock.
Note 2: The earbuds themselves have ipx4 (sweatproof) rating, the charging dock is not sweatproof/waterproof.
