The earbuds will automatically shut down after 1 hour when they are outside the charging case and not connected to a device. When the connection range of the earbuds is exceeded, the earbuds automatically enter a waiting connection state. If no device is connected after 1 hour, they will automatically shut down.
Note:
Put the earbuds into the charging case, and the earbuds will automatically charge. After the earbuds are fully charged with the lid closed, they will enter a shutdown state.
