Owners of popular TWS-Xiaomi headphones often face a situation where devices stop working in pairs; instead of stereo, the user hears music only in one ear, or both channels play the sound independently of each other, creating a chaotic hum. This does not mean that the gadgets are broken or require expensive repairs in the service center.
In most cases, the problem lies in the failure of software responsible for synchronizing between the left and right buds, the system could lose information about which device is master and which is slave. Fortunately, the procedure for restoring communication between them is quite simple and does not require special technical skills.
In this guide, we will take a detailed look at the action algorithm for Mi True Wireless Earbuds models from different generations, learn how to reset and force pairing correctly, which will return your headphones to a full stereo sound. Follow the instructions carefully to avoid errors in settings.
Reasons for the desynchronization of wireless headphones
Before you start taking action, it's important to understand the nature of the problem, because out-of-synchronization is a condition where you lose communication between two components of a headset, most often because one device has run out before the other.
When you put your headphones in a case, but one of them doesn't have time to charge fully or loses contact with the pins, its software can "sleep" deeper than it should. The next time you remove the gadget, it does not have time to quickly find a "partner" and starts to work offline, and interference from other Bluetooth devices can also cause.
Another factor is a firmware update or a smartphone change. If you've connected your headphones to a new phone but haven't removed them from the list on the old one, there may be a conflict of MAC addresses, resulting in one ear connecting to the phone and the other remaining hanging waiting to connect to the first one.
⚠️ If after extraction from the case, the indicators flash with different frequency or color, this is a sure sign that the headphones do not see each other and require forced combination.
Understanding these mechanisms helps avoid future errors, such as always keeping the contacts clean in the charging case, and dirt or oxidation can prevent one channel from charging properly, leading to desynchronization.
Preparation for the reconnection procedure
To successfully perform the reconnection procedure, you need to properly prepare the equipment, do not try to connect devices on the go or in a place with a bad signal, find a quiet place where there are not many active Bluetooth signals nearby.
The first step should always be to completely clean the pairing list on your smartphone. Go to Bluetooth settings, find your Xiaomi Earbuds in the list, and select the option “Forget the device” or “Unpair the pairing.” This is a critical step that is often ignored.
After removing the device from the phone’s memory, you need to turn off Bluetooth on the smartphone itself, which will prevent an attempt to automatically connect during the setup process, which could interrupt the synchronization procedure between the headphones themselves.
- 📱 Remove the headphone profile from the smartphone memory via the Bluetooth menu.
- 📶 Turn off the wireless module on your phone completely.
- 🔋 Make sure the charger case and the headphones themselves are charged at least 50 times%.
- 🧹 Wipe the charging contacts on headphones and inside the case with dry cloth.
Only after doing this preparatory work can you move on to direct reset and connection, and ignoring the cleaning phase of the phone's memory is the most common mistake that makes it impossible for users to connect the two channels.
💡
Before starting the procedure, close all applications that use sound (YouTube, Spotify, voice recorder) so that they do not intercept the audio stream during the connection.
Algorithm reset and pairing headphones Xiaomi
There is a universal method that is suitable for most models of Mi True Wireless Earbuds, including versions Basic, 2S, Air and Pro. The essence of the method is to force the restart of communication modules inside the headphones themselves.
Put both earbuds in the charge case. Make sure they fit tightly to the contacts and the indicators inside the case (or on the headphones themselves, depending on the model) signal the start of charging. Close the case cover and wait about 10 seconds.
Take both of the earbuds out of the case at the same time. Don't touch the touch zones at this point. You have to wait for them to go into pairing mode. This is usually indicated by the flashing of the lights quickly. If only one flashes, then the second one hasn't activated.
☑️ Testing of preparedness for discharge
Now you have to do a reset action. Most Xiaomi models have to press and hold the touch zones on both headphones simultaneously for 5-10 seconds. Some versions, such as the Mi Air 2, have a physical button on the case case case.
If you use a button on the case: open the lid without removing the headphones, and press the button for 10 seconds. The indicator should flash white several times, which signals a successful reset to the factory settings, after which the headphones should automatically start searching for each other.
⚠️ Warning: While holding sensors, the headphones may issue audible signals or voice commands. Do not let your fingers go until the indicators change the pattern of blinking (usually flashing red or flashing white quickly).
Features of setting up different models Xiaomi
Xiaomi’s audio lineup is quite extensive, and procedures can vary slightly depending on the generation and series.Knowing the nuances of your particular headset model will help save time.
The Mi True Wireless Earbuds Basic series is characterized by the absence of a button on the case, which is done solely by pressing the touch panels of the headphones themselves when they are outside the case, and it is important to get into the timing: you need to hold for about 20 seconds until the red blink.
Air and Air 2 series models often feature pairing button cases, which prioritize mechanical action on the case, and the sensors on the headphones themselves can only control the music, not the system settings.
Flagship models such as the Mi True Wireless Earphones 2 Pro can support wireless charging, and when performing reset procedures, it is recommended to remove such cases from wireless charging panels to avoid interference with the indicator.
| Model headphones | Type of discharge | Success indicator | Retention time |
|---|---|---|---|
| Mi True Wireless Earbuds Basic | Headphone sensors | Red flashing | ~20 seconds |
| Mi Air 2 / 2S | The button on the case | White flashing | 10 seconds. |
| Mi True Wireless Earphones 2 Pro | The button on the case | Orange light | 10 seconds. |
| Redmi AirDots | Sensors (5 times) | Fast blinking. | 5 clicks |
Always pay attention to the color of the indicator. In the Xiaomi ecosystem, white usually means ready to pair, red means low charge or reset mode, and orange means the charging process or error.
What to do if the indicators do not light up?
Completion of synchronization and connection to the phone
Once you've done the reset, the headphones must go into search mode, which usually takes 5 to 15 seconds, at which point one of the headphones (left or right) will be in charge, and the other will connect to it.
Visually, this is determined by the change in the frequency of blinking, where both of them were blinking before, now only one (usually the left) should blink, and the second should either go out or blink very rarely, which means that the stereo is assembled.
Now you can turn on Bluetooth on your smartphone. Click "Search for New Devices." You should have one entry on your model's name. If you see two identical entries (like two "Mi True Wireless"), then the sync failed and you need to repeat the procedure.
Click on the name of the device to connect. After a successful couple, the status will say "Connected" (or "Connected"), and in the headphones you will hear a voice message or a characteristic beep.
- 🎧 Turn on Bluetooth on your smartphone and start searching.
- 🔍 Find one device in the list with the name of your model.
- 📲 Then, click on the slate and wait for confirmation.
- 🎵 Check the sound: music should be in both ears at the same time.
⚠️ Warning: If the phone sees two devices with the same name, don't try to connect them separately.This will lead to mono mode.
Diagnostics and troubleshooting
Even with strict follow-up, nuances can arise. If you can't connect two Xiaomi headphones, it's worth checking for less obvious reasons. Often the problem is not software failure, but the physical state of the contacts.
Oxidation of contacts - the scourge of all TWS-Sweat, moisture and skin fat create a film that doesn't conduct current. The earpiece thinks it's not in the case, and it's not charging, and then it's not synchronizing. Wipe the contacts with a cotton swab dipped in alcohol.
It’s also worth checking out the Bluetooth version on your smartphone. Older phones may not work properly with new audio protocols. Try connecting your headphones to another device (tablet, laptop) to prevent the smartphone itself from breaking.
If neither method works, there may be a problem with the hardware of one of the modules, in which case the software reset is powerless, but before you carry the device for repair, try to completely discharge the case and headphones to zero, and then charge them to 110% (leave on charging for a couple of hours after the light light lights go out).
💡
If after all the manipulations, the headphones work only in mono mode on different devices, a hardware malfunction of the Bluetooth module in one of the channels is likely.
Prevention of connection problems
In order to avoid the question of how to connect two Xiaomi headphones in the future, you should adhere to simple rules of operation. Regular maintenance prolongs the life of electronics.
Always put your headphones in your case immediately after use. Do not leave them on the table, as they may become discharged or accidentally connect to an outside device.
Once a month, a full charge-discharge cycle is recommended, which helps calibrate the power controller, and it is also useful to update the headphone firmware through the Mi Wear or Xiaomi Earbuds app, if the manufacturer provides this option.
Keep cool devices safe. Overheating in the sun or overcooling in the winter can cause the communication modules to temporarily fail. TWS-headphones throughout their lifetime.
