Xiaomiβs modern wireless headphones are famous for their sound quality and affordable price, but even reliable devices sometimes fail. Users often experience a situation where the left and right channels stop working in pairs, turning into two independent sound sources, a phenomenon known as desynchronization, can occur after one of the modules is discharged or a software failure.
Recovering the True Wireless Stereo (TWS) headset doesn't usually require a service center, and in most cases, the problem is solved by forcing devices to pair with each other, and then you have to run a certain algorithm that resets the memory of previous connections and makes the headphones find each other again.
Itβs important to understand that the process of reconnecting depends on the specific model of your device. Some versions of Mi True Wireless Earbuds require mechanical reset through the touch areas, while other models need to use a charging case. In this article, we will discuss all the details so that you can return your headphones to full operation.
Reasons for the desynchronization of the left and right channel
The main reason for the loss of communication between the headphones is the uneven discharge of the batteries. If you remove the right earphone from the case, and the left left left is lying inside or discharged during use, the communication between them is interrupted. TWS-Headsets are arranged so that one channel (master) broadcasts the sound to the second (slave), and when the master is lost, the slave goes into standby mode.
The second common cause is connectivity conflict, where the smartphone could remember the left earbud as a separate device and the right earbud as another, and as a result, when you try to play audio, the system tries to send a signal to only one of them, and malfunctions in the microcontroller inside the headset can be caused by static electricity or a sharp voltage drop.
β οΈ Warning: Do not try to charge your headphones while performing the reset procedure.This can lead to errors in the memory data recording and exacerbate the problem of desynchronization.
Sometimes the problem lies in the software of the smartphone itself. Updating the Android or iOS operating system can change the algorithms of the Bluetooth stack, which causes the old settings to stop being read correctly by the gadget, in which case not only the reconnection of the headphones helps, but also cleaning the list of conjugated devices in the phone.
Preparation for pairing: cleaning the memory of the smartphone
Before you force Xiaomi headphones to be connected, you have to completely remove them from your mobile deviceβs memory, which is a critical step that is often ignored, leading to repeated errors, and you have to go to the Bluetooth settings and find all the entries associated with your model in the list.
Select the device and click "Forget this device" or "Disable." If the list shows two identical names (e.g., "Mi AirDots" and "Mi AirDots L"), delete both. After that, it is recommended to turn off Bluetooth on the phone to exclude any background attempts to connect during settings.
βοΈ Pre-reset check
Make sure the charger case and the headphones themselves have enough energy. If the battery is zero, the procedure can be interrupted halfway. The optimal charge is about 50-70%. Place both earphones in the case and let them stand there for 5-10 seconds so that they go into charging mode and "wake up."
Universal method of discharge through sensory zones
The most common way to reconnect most Xiaomi models, including the Mi True Wireless Earbuds Basic and Redmi AirDots. It is based on prolonged pressing of touch panels. First, remove both headphones from the charging case. Make sure they are turned off (the indicators do not burn).
Press and hold the touch zones on both headphones simultaneously. Hold for about 5-7 seconds until the lights turn red. Then release your fingers. The headphones should turn off. Now repeat the procedure: press the sensors again for 10-15 seconds. This time wait until the lights flash white several times and go out.
- π΄ First long press (5-7 (s) switches off the device forcibly.
- βͺ Second long press (10-15 (s) initiates the resetting and reconnection mode.
- π After reset, the indicators should flash white often, which means a pair search mode.
After doing this, the headphones must automatically find each other, and usually one (most often the right one) will blink slowly, and the other will stop signaling or blink very rarely, which means that the stereo is restored, and now they are ready to connect to the phone.

If the headphones don't connect after reset, try putting them back in the case for 10 seconds and then pulling them out at the same time, which will help restart the communication module.
Specifics of setting models with a button on the case
More advanced models, such as the Mi True Wireless Earphones 2 or Xiaomi Buds 3, often feature a function button on the case of the charging case, which greatly simplifies the process of pairing and resetting, in such devices the basic logic of the operation is tied to the state of the case.
To reset, place the headphones inside the case and leave the lid open. Find a round button on the case (usually located at the bottom or on the end). Press and hold this button for 10 seconds. The indicator on the front of the case should light up in orange, which signals the transition to reset mode.
Once the light flashes white, release the button. The headphones inside the case are dropped. Close the lid and open it again, automatically reconnect the left and right channels. If your model has Fast Pair, the connection animation may appear on the smartphone screen.
β οΈ Note: When using the button on the case, make sure the headphones fit tightly to the contacts. If the contact is broken, the reset may not pass, as the system will not see the device inside.
In some cases, it takes a short press (2 seconds) to activate the pairing mode, and a long press to reset. Always pay attention to the color of the indicator: white usually means ready to connect, and orange or red - setup mode or error.
Features of pairing different Xiaomi series
Xiaomiβs wireless audio lineup is extensive, and different series can have unique algorithms. Understanding the differences between the AirDots, Redmi Buds and flagship Mi Buds series will help avoid errors. Below is a table that systematizes reset methods for popular models.
| Series of devices | Management method | Indication of discharge | Features |
|---|---|---|---|
| Mi True Wireless Basic | Sensor (5+10 sec) | Double flashing red | No support for the app |
| Redmi AirDots S | Sensor (20 sec) | Triple flashing. | Improved Bluetooth 5.0 |
| Mi Buds 3T | Case button (10 seconds) | Orange light | Support for ANC |
| Xiaomi Buds 4 | Annex/Case | White pulse | Spatial audio |
For active noise cancelling (ANC) models, the procedure can be a little more complicated due to the presence of additional microphones and processors. If a standard reset doesn't work, try using the official Xiaomi Earbuds or Mi Home app. In the device settings inside the app, there is often a "Reset headphones" button that performs the software Hard Reset.
FlipBuds owners should be aware of magnetic sensors. If the headphones can't see each other, maybe the problem is the foot sensor, which thinks the earpiece is in the ear and doesn't have pairing mode. Cleaning the sensors with a dry cotton swab can solve the problem.
Diagnostics and troubleshooting connection
If you don't get the results from all the attempts to connect the headphones, you need to do a deeper diagnostics. First, check if your device is visible to other smartphones. Try connecting to the headphones from a friend's phone or tablet. If it works, the problem is in the Bluetooth module of your main phone.
It's a common mistake to try to plug headphones in while they're in phone search mode instead of each other. Remember, they have to pair up first (TWS Link), and then they're visible to the smartphone. If you see two separate devices with the same name on the Bluetooth list, then TWS mode is not activated.
- π± Make sure your phone is not in the "Only one audio device" mode".
- π Check charging contacts in the case β oxidation can interfere with data transfer.
- πΆ Stay away from powerful Wi-Fi routers when pairing.
In rare cases, a full discharge is required. Leave the headphones on outside the case until the battery is completely depleted, then charge them to 100% when turned off.This helps calibrate the power controller and can eliminate software errors.
What to do if only one headphone is working?
Using the Xiaomi Earbuds app to customize
For owners of modern Xiaomi models, the official Xiaomi Earbuds app (or Mi Home for the ecosystem) will be a great assistant, which allows you not only to manage the settings of the equalizer, but also to perform Firmware diagnostics. Outdated firmware is a common cause of unstable communication.
Connect your headphones to your phone (even if you have one channel) and open the app. If the device is supported, you'll see its status and charge level. Go to settings and check the Software Update section. If a new version is available, be sure to install it. The update process often reflashes the communication module, eliminating sync bugs.
β οΈ Note: During the update of firmware through the application, you should not open the case cover (if the model implies this) or move away from the phone.
The app also offers headphone search and gesture settings. Sometimes reassigning gestures (such as turning off the triple tap) can reduce the number of false sensor positives that the system perceives as a command to turn off or reconnect.

Timely firmware updates through the official app solve 80% of software problems with communication between the channels of Xiaomi headphones.
