Why is one headphone Xiaomi silent and how to turn both on: all ways to solve it

The problem of one of Xiaomi’s wireless headphones refusing to work is familiar to many owners of Redmi AirDots, Mi True Wireless, Buds or FlipBuds models, most often after updating the firmware of the smartphone, discharging the headphone battery or accidentally resetting the settings. In 90% of cases, the malfunction is software-based - and it can be fixed without contacting the service center.

If your headphones don't sync after falling or getting moisture, check them for physical damage first, in which case repairs may be needed.

1. Checking basic settings: what to do first

Before you start to do complex manipulations, make sure that the problem is not the basic settings.

βœ… Charge level. One of the headphones could have been more severe than the other. Place both earphones in a case for 10 to 15 minutes, then remove them and try to reconnect them. 3T Pro and newer indicator on the case shows the charge of each headphone separately – if one of them does not blink, its battery is completely discharged.

βœ… Bluetooth on your device. Make sure Bluetooth is on on your smartphone/PC and the headphones are within range (no more than 10 meters without obstacles). On Android, check if the charge saving mode is activated - it can turn off background connections.

βœ… Connect to another device. Sometimes the headphones stick on the previous gadget (for example, a laptop or tablet), go to the Bluetooth settings on all devices that the headphones have previously connected to, and remove them from the list of associated devices.
