Edifier Tws NB2 User Manual: How to charge the Edifier Tws NB2? Charging the earbuds When being used, if a red light starts flashing instead of blue light, this means that the earbuds are low on battery power. To charge them, all you have to do is place them correctly in their charging case, as long as it has enough battery. While charging, they will have a red light on, and when fully charged, the light will turn off automatically. Charging the charging case Just as in the case of earbuds, if a light turns on and blinks in the charging case, it means that it has a low battery level, and the idea is to charge them as soon as possible by connecting them through its charging port to the charger specialized with which it comes. In case this is not possible and the charging case runs out of battery completely, the earbuds will not work. While charging, light indicators will turn on one by one indicating the battery level you have, and when fully charged, all the lights will stay on.
