Many Xiaomi wireless headphone users are faced with a situation where one of the headphones stops working or the sound is played in only one channel. This is a common problem of desynchronization, which is often solved without going to the service center. Proper synchronization of devices allows you to restore full stereo sound and a stable connection to the smartphone.
In this article, we will discuss in detail the algorithms for forced pairing of headphones with each other, you will learn how to perform a full reset (Hard Reset) for various models, including the Mi True Wireless Earbuds series and Redmi Buds.
Before starting the procedure, it is important to understand that the recovery process depends on the specific modification of the device. Some models require the retention of touch zones, while others are equipped with physical buttons on the case.
Reasons for the desynchronization of wireless headphones
Understanding the root cause of the failure helps you choose the solution more quickly, most often desynchronization occurs due to a software failure in the firmware of the Bluetooth module of one of the headphones, in which case the devices stop “seeing” each other as a single pair.
The second common cause is the different battery levels in the left and right earbuds, so if one device is completely depleted, it may have shut down earlier and lost communication with the main channel, and external interference may also affect it.
Sometimes the problem lies in the Bluetooth cache on the smartphone itself, and the build-up of pairing errors causes the phone to try to connect to only one channel, in which case cleaning the list of devices helps.
- 🔋 Different level of charge in the left and right headphone.
- 📡 Interference signals from Wi-Fi routers or microwave ovens.
- 📱 Errors in the cache of the Bluetooth module of the smartphone.
- ⚙️ Failure of the firmware after a failed update.
It is worth noting that active noise cancellation (ANC) models are more sensitive to software errors, and complex electronics require both channels to work smoothly to process sound correctly.
Preparation for the recovery procedure
Before you start forced mating, you have to do a series of preparatory steps, which is a critical step that is often ignored, which leads to repeated failures. First, make sure that the headphones are sufficiently charged.
⚠️ Warning: Do not start the reset procedure if the charge of the case or headphones is below 20.
Next, clear the connection history on your smartphone. Go to Bluetooth settings, find your Xiaomi Earbuds, and select Forget Device or Unpair. This will remove the old encryption keys.
Then turn off Bluetooth on your phone. Put both earbuds in the charge case and close the lid. Wait 10-15 seconds for the devices to go into standby mode and complete the background processes.
☑️ Preparation for discharge
Now that the preparatory phase is complete, you can move on to direct synchronization, and it's important to do everything consistently and without haste.
Method 1: Synchronization through sensory control
This method is suitable for most Xiaomi and Redmi models that do not have a physical button on the case, the main task is to simultaneously activate pairing mode on both headphones.
Remove both earphones from the case. At the same time, touch the touch areas on both devices and hold your finger for 5-7 seconds. The indicators should blink to signal the transition to settings.
Then put both headphones back in the case without closing the lid. Wait about 5 seconds, then retrieve them. If the procedure is successful, the indicators should flash at different frequencies or colors, indicating that they are looking for each other.
Turn on Bluetooth on your smartphone and find the device on the list of available ones. When you connect, sound should appear in both channels. If this does not happen, repeat the procedure, increasing the retention time of the sensors.
What to do if sensors do not respond?
Some models require double or triple touch instead of prolonged retention. Experiment with the number of taps if the standard method fails.
Method 2: Reset through a button on the charging case
Flagship models like the Mi True Wireless Earbuds Pro or Xiaomi Buds 3 often feature a physical button on the case of the charging case.
Put both earphones in the case and leave the lid open. Find a circular button on the back or bottom of the case. Press and hold it for a period of time. 10-15 seconds.
Watch the LED light on the case, it should start flashing white or orange (depending on the model), and then go out or change the pattern of blinking, which is a signal that the factory settings have been restored.
| Model | Action. | Indication of success | Retention time |
|---|---|---|---|
| Mi True Wireless Earbuds Basic 2 | 5 touches of the sensor | Blink 3 times | ~5 sec. |
| Redmi Buds 3 Pro | The button on the case | Orange light | 10 seconds. |
| Xiaomi Buds 3 | The button on the case | White flashing | 10 seconds. |
| Mi True Wireless Earbuds Pro | The button on the case | Orange light | 10 seconds. |
After a successful reset, close the case cover for 10 seconds, then open it and press the button once briefly to enter pairing mode, and you can now connect the headphones to your phone as a new device.
💡
The button on the case resets the settings of both headphones at the same time, which ensures that they are synchronized with each other.
Solving problems with connecting one headphone
When only one earpiece is running (usually the right earpiece, as it is often a master device), a special approach is required, in which case the search for the second channel must be forced.
Remove the device from the Bluetooth list on your phone. Put the working earphone in the case, leave the non-working one outside. Press the pairing button on the case (if any) or tap the sensor on the working earphone.
Now try connecting your phone to a broken earphone directly if it appears in the list. If that's not possible, do the full reset described in the previous sections, paying special attention to charging the problem channel.
⚠️ Warning: If one earphone is not charging in the case, wipe the contacts with alcohol. Contact oxidation is a common reason that the device does not turn on and sync.
Sometimes, "re-steaming" helps. Connect the phone to one earphone, then in Bluetooth settings, select the "Plug" option for the second device if the system allows you to do it manually.
In rare cases, you need to flash through the official app, which is a complex process that we'll discuss in the next section.
Using the Xiaomi Earbuds app to customize
The official Xiaomi Earbuds app (or Mi Buds M8) is a powerful diagnostic tool that allows you not only to customize the equalizer, but also to update the firmware, which often solves the problems of desynchronization.
Download the app from Google Play or the App Store. Connect your headphones to your smartphone and start the program. If you see the devices, the app will prompt you to update the software.
The upgrade process requires a stable connection. Put the headphones in the case, plug the case into the charger, and leave it next to the phone. Do not open the lid until the process is complete.
Path in the application: Device profile → Update check → Download and install💡
During the firmware update, keep your phone as close to the headphones as possible (no further than 10 cm) to avoid data packet loss and recording errors.
Once the firmware update is in place, the headphones will automatically restart and perform internal synchronization, the most reliable way to fix software bugs.
