The problem of one of Xiaomiβs 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.
In this article, weβll look at all the possible reasons why a single headphone doesnβt connect, make a sound, or display as a standalone device on the Bluetooth list. Youβll get step-by-step instructions for Android, iPhone, and Windows, and how to avoid similar problems in the future.
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.
β 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 β if one of them does not blink, its battery is completely discharged.
β 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.
β 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.
- π Charge the case and headphones. Connect the case to charge for 30 minutes, even if the indicator is on.
- π± Rebooting your smartphone: A simple but effective way to reset the time errors of a Bluetooth module.
- π Resetting the network on a smartphone. On Android: Settings β System system β Reset β Resetting Wi-Fi, Mobile Network and Bluetooth.
β οΈ Note: If Xiaomi headphones connect as two separate devices (e.g. Mi True) Wireless_L and Mi True. Wireless_R), Don't try to plug them in separately, it will cause the sync to break. You'll need to reset your headphones first (more on that below).
2.Resetting headphones Xiaomi: a universal way
If the basic checks didn't work, the next step is to reset the headphones hardware, which will bring them back to factory settings and make them sync again, and the instructions are suitable for all models, including the Redmi AirDots 3, Mi True Wireless 2 and Buds 4.
