1. When the charging case battery is at 1%, the case will shut down, causing the button to become unresponsive. This is not an earbud malfunction. If you experience a low battery shutdown, please connect the charging case to a power source with the lid closed to recharge it.
2. In areas with significant environmental interference (such as numerous signal transmitters/receivers or other interference factors caused by weather), the earbuds and charging case may occasionally disconnect. Please check for environmental interference factors. You can open and close the charging case lid to reconnect the earbuds.
*Reconnection takes approximately 3-4 seconds.
3. double tap & hold function:
To reduce accidental touches in certain scenarios, the product design includes a double tap & hold function to temporarily disable the charging case button. If you accidentally disable the button, use the Smart Dial on the charging case to perform double tap & hold, or place both earbuds back in the charging case, close and reopen the lid to restart the charging case Smart Dial function.
*This feature can only be used if the charging case Smart Dial function is set in the app.
