Xiaomi wireless headphone users often face a situation where devices stop working in pairs or the phone sees only one of them. This is a common problem associated with desynchronizing Bluetooth modules inside the case. Unlike wired headsets, it requires a precise sequence of actions to restore communication between the left and right earphones.
The process of restoring the functionality of the gadget does not require deep technical knowledge, but ignoring certain nuances can lead to the fact that the procedure will have to be repeated several times. Modern models such as Mi True Wireless Earbuds Basic 2 or Redmi Buds 3, have their own reset features that distinguish them from the first generations of Airdots.
In this guide, we will go into detail all the steps of forced synchronization, from completely cleaning the phone’s memory to fine-tuning through hidden menus. It is critical to reset the Bluetooth settings on your smartphone before you start pairing, otherwise the phone will try to connect to the old profile of the device.
Preparation for forced synchronization of devices
Before you start to act, you need to make sure that both earbuds are sufficiently charged. If the battery is discharged, the indicators may not light up the desired color, which will confuse you during the diagnosis. Put both earbuds in the charging case and leave them there for at least 30 minutes.
The next step is to clear the list of paired devices on your smartphone. Go to Bluetooth settings, search for Xiaomi Earbuds or Airdots list, and select the option “Forget the device” or “Unpair the pairing” that will delete the stored encryption key that could have caused the conflict.
⚠️ Warning: After removing the device from the list, do not immediately try to search for it again. First, you need to perform a full reset of the headphones themselves, otherwise they will remain in the waiting mode of the old connection.
It's also recommended that you turn off the wireless module on your phone completely, and then turn it back on, and this action will restart the protocol stack and clear the temporary search errors, and you're now ready for the main step of restoring communication between the modules.
Method of resetting headphones Xiaomi
There are several ways to get the gadget back to factory status, and the choice of method depends on the specific model of your device. For most versions of Airdots and Redmi Airdots, the classic method works using touch panels. Remove both earphones from the case.
Make sure they're off.If they're on, press the touch areas on both devices simultaneously and hold for about 5-7 seconds until the lights go out.Now that they're off, tap and hold the touch panels on both headphones simultaneously for 20 seconds.
- 🔴 First-time 5-10 Seconds the indicators will flash red – this is the mode of off and preparation.
- 🔵 They can then flash white or blue, which means entering reset mode.
- 🔴 After a few seconds, the indicators should flash red twice and go out - the reset was successfully performed.
Some models, such as the Mi True Wireless Earphones 2, may have different procedures, often requiring you to put your headphones in a case without closing the lid, and press the buttons on the devices themselves or on the case. Always check the instructions for your particular version if the standard method fails.
☑️ Checklist before reset
The process of pairing left and right earphone
After a successful reset, the headphones go into automatic search mode, at which point one of them (usually the right one) becomes a master device, and the other becomes a slave device, and your task is to wait for them to find each other before turning on Bluetooth on the phone.
Remove both earbuds from the case at the same time. Don't touch them for a few seconds. The indicators will flash quickly white, signaling a pairing. When the connection between them is established, one of the indicators (most often the left one) will go out or start flashing very slowly, and the right one will continue to blink rapidly.
Now you can activate a search on your smartphone. Turn on Bluetooth and start the scan. The list should show one device, not two. If you see two identical names, then the synchronization between the headphones has not occurred, and the reset procedure should be repeated.
What to do if the lights flash different colors?
It's important not to press any buttons at this point. Let the TWS (True Wireless Stereo) protocol complete the handshake between the modules by itself, only after you've made sure that there's one device on the phone's list, you can click on it to connect.
Features of connection to different operating systems
The connection process may vary slightly depending on the version of your smartphone’s operating system. Android device owners have more access to codec settings and additional features through the Mi True Wireless app.
iOS users may find that the system does not display the charge level of each headphone separately without third-party applications. However, the basic functionality and sound quality remain identical.
| Parameter | Android (MIUI/OneUI) | iOS (iPhone/iPad) | Windows 10/11 |
|---|---|---|---|
| Application for setting | Mi True Wireless Earbuds | No (third-party only) | No. |
| Codecs. | SBC, AAC, aptX (depending on model) | SBC, AAC | SBC, AAC |
| Sound delay | Low (in games) | Medium | Tall. |
| Gesture management | Complete reconfiguration | Standard. | Standard. |
On Windows computers, there is sometimes a problem with sound quality when using a headset for calls. The system can switch the profile to Hands-Free AG Audio, which dramatically reduces bitrate. For music, always choose a Stereo profile in the audio settings.
💡
For Android owners, download the official Mi True Wireless Earbuds app from Google Play, which allows you to update the firmware of your headphones, which often solves problems with connection stability.
Diagnostics and elimination of connection errors
Even after proper synchronization, periodic communication breaks can occur, most often due to radio interference in the 2.4 GHz band. Wi-Fi routers, microwave ovens and other Bluetooth devices can create porridge on the air, interfering with stable data transmission.
If the sound is interrupted in only one headphone, check if the signal is blocked by your body. The antennas in Xiaomi budget models are not always optimally located, and the hand covering the body can shield the signal. Try changing the phone into the other hand or pocket.
- 📶 Check the distance: make sure the phone is no further than 10 meters and without physical obstacles.
- 🔋 Battery charge: At low charge, transmit power can be reduced to save energy.
- 📱 Phone Reboot: The banal OS restart often solves problems with Bluetooth drivers.
⚠️ Warning: If one headphone is permanently disabled, try connecting them to another phone. If the problem persists on another device, then the hardware malfunction, and the software reset will not help.
In some cases, disabling the Absolute Volume feature in the Android developer menu helps, which can eliminate the volume dissynchronization between the phone and the headphones, which is sometimes perceived as a connection error.
Use the Mi True Wireless Earbuds app
For deep customization and synchronization status check, it is highly recommended to use proprietary software.The Mi True Wireless Earbuds app is available on Google Play and allows you to see the charge of each headphone individually, which is impossible to do in the standard Bluetooth menu.
Once you have your headphones on, open the app, it automatically defines the model and prompts you to update the firmware if a new version is available. The firmware contains protocol bug fixes, so this step is critical to stable operation.
Inside the app, you can reassign the touch functions, for example, if you double tap to an assistant and you need to switch tracks, that's easy to change, and there's also a headphone search feature that makes them make a loud sound if you lose them at home.
💡
Regularly updating your firmware through the app is the best way to prevent future sync issues and improve the quality of your audio codec.
