Basic synchronization of headphones Xiaomi: the first launch
If you’ve just bought a Xiaomi headphone or dropped it to factory settings, the first thing you need to do is to do the initial synchronization, which automatically links the headphones to each other and to the source device (smartphone, tablet, PC).
- Remove both headphones from the case - they should turn on automatically (the indicator will light up).
- Wait for the white/red light to flash, which means the headphones are ready to pair.
- Activate Bluetooth on your smartphone and find the device in the list of available. The name will contain a model (for example, Mi TrueWireless 2 or Redmi Buds 3 Lite).
- Connect to headphones – after a successful connection, the indicators on both headphones should light up in blue or purple (depending on the model).
If the headphones are synchronized correctly, you'll hear the connection sound in both speakers, and if you only have one, go to the troubleshooting section.
💡
On some models (for example, Xiaomi Buds 4 Pro) to activate the pairing mode, you need to hold the touch panel on the case for 5 seconds until the indicator starts flashing white and red.
Manual synchronization if the headphones do not connect automatically
If the headphones don't sync with each other after being removed from the case (for example, one of them is not detected or only sounds in one), try forced pairing. This method works for most models. Xiaomi/Redmi:
- 🔋 Completely discharge both headphones (wait until they turn off), then charge them in a case to 100%.
- 📱 Remove headphones from the list of Bluetooth devices on your smartphone (forget the device).
- 🔄 Reset your headphones: Place both earbuds in the case and close the lid. Press and hold the button on the case (or touchpad) for 10-15 seconds until the indicator flashes red and white. Remove the headphones - they should automatically sync.
Connect again.
If the headphones don’t sync after reset, check if another device is blocking the connection (for example, a second smartphone or laptop that the headphones used to connect to), turn off Bluetooth on all other gadgets and try again.

Tips for stable work of headphones Xiaomi
To avoid synchronization problems in the future, follow these guidelines:
- 🔄 Regularly update your firmware through the official app. New versions fix connection errors.

- 🔋 Charge the case to 100% at least once a week – this prevents synchronization failures.
- 🎵 Turn off your headphones correctly: first put them in the case, then turn off Bluetooth on your smartphone.
If you use Windows or Mac headphones, install the latest Bluetooth drivers. On PC, sync problems are often solved by reinstalling the Bluetooth adapter through Device Manager.
💡
The most common reason for earphones to disconnect is the low charge of the case, and even if the headphones themselves are charged, a case below 20% can interrupt synchronization.
