Wireless speakers often face a situation where the right and left channels stop working in pairs, playing sound independently of each other. This is a common problem for TWS (True Wireless Stereo) technology, which underlies most modern models from Xiaomi and Redmi.
It usually takes only a couple of minutes to reconnect between devices, if you know the correct algorithm, and you don't need any software or service center, because the procedure is done with hardware buttons, and it's critical to understand that the process requires a complete break of old connections before you start a new setup.
In this article, we will go into detail all the steps to restore your headphones, we will look at standard reconnection methods, how to force resets for different models, and how to solve specific Bluetooth errors. Following the instructions will allow you to enjoy stereo sound again without delay and desynchronization.
Reasons for the desynchronization of wireless headphones
Understanding the cause of a failure helps prevent it from happening again in the future, and most often, the problem is that one of the Bluetooth modules loses touch with the master device (usually the right earpiece) and starts looking for a connection on its own, which causes the phone to see two separate devices with the same name.
Another common cause is residual charge in a case during long-term storage. If the Redmi Buds or AirDots headphones were lying unused for several months, their internal memory could retain pairing errors, and third-party applications that intercept control of the audio stream also influence.
And don't forget about the physical factors, because the mud on the charging contacts inside the case can cause one earphone to charge worse than the other, and it causes a voltage imbalance, and the device with a lower charge can behave unstable, losing touch with its "brother".
⚠️ Warning: If one of the headphones is discharged more than the other, synchronization is not possible.Be sure that both modules are charged at least 50% and are in the case for at least 10 minutes before starting any action.
Preparation for the synchronization procedure
Before you start the action, you have to do a number of preparatory steps, and ignoring this step 80 percent of the time, it doesn't work the first time, and you have to clear the list of conjugated devices on your smartphone.
Go to your phone’s Bluetooth settings, find your headphones (like Redmi Buds 3 or AirDots) in the list, and click “Forget Device” or “Delete.” After that, be sure to turn off Bluetooth on your phone so it stops looking for the device in the background.
☑️ Preparing headphones for reset
Now you have to remove both headphones from the charge case at the same time, and if you take them out in turn, they may not be paired with each other, and the lights should be lit up by LEDs, signaling readiness to work.
Standard Reset Method for Redmi and Xiaomi Models
Most modern models, including the Redmi Buds 3 Pro, 4 and Xiaomi Buds, use a single reset logic through touch panels, which is the most secure method and does not require complex manipulation of the buttons on the case.
Remove both earbuds from the case. At the same time, touch the touch areas on both earbuds and hold your finger for 5-7 seconds. The indicators should flash red or change the pattern of blinking, which signals a successful reset.
Then put the devices back in the case and close the lid. Wait about 10 seconds, then open the case again. The headphones should automatically find each other, and one of the indicators (usually on the right) should go out or flash less often, indicating master-slave connection.
Status indication
Turn on Bluetooth on your phone and search for new devices. Only one name of your headphones should appear on the list. If you see two identical names, repeat the procedure, paying more attention to touching the sensors simultaneously.
Hardware reset via a button on the case
Some models, such as the Xiaomi Mi True Wireless Earbuds Basic 2 or Redmi AirDots S, have a physical reset mechanism.
Place the headphones inside the case, leaving the lid open. Find a function button (sometimes paired with a charge indicator). Press and hold it for 15-20 seconds. The indicator on the case should light up in orange or white, after which a quick blink will begin.
💡
For models without a visible button, try pinching the touch zones on the headphones themselves without removing them from the case if the design allows access to the sensor.
This method forcibly clears the internal memory of the modules, and once the indicators stop flashing, close the case, and now the devices are in a factory state and ready to pair as new.
Specificity of connecting different TWS models
The lineup of audio devices from Xiaomi and Redmi is huge, and the nuances may differ. For example, in the Redmi Buds 3 Lite model, a reset occurs when extracted from the case if they were pre-discharged to zero. whereas Xiaomi FlipBuds Pro requires the use of the Xiaomi Earbuds app for deep tuning.
Below is a table with features for popular series:
| Model | Resetting method | Indication of success |
|---|---|---|
| Redmi AirDots | 5 sec sensor + case button | Fast blinking. |
| Redmi Buds 3 | 7 seconds sensors simultaneously | Red flashing |
| Xiaomi Buds 3T | 10 seconds sensors | Sound signal |
| Redmi Buds 4 Pro | Through an app or 10 seconds | Voice menu |
If your model isn't listed in the chart, try a universal method: pinch the sensors for 20 seconds. This works for 95% of the brand's devices. It's important to keep your fingers on the table, even if the headphones are starting to make sounds.
Solving problems with sound desynchronization
Sometimes the headphones are connected, but the sound comes from only one channel, or the stereo effect is missing. This may be due to the developer's settings in Android or the features of the codecs. Check if the mono-audio mode is activated in the special features of the phone.
Go to Settings → Special Features → Hearing Improvement and make sure the Monoaudio switch is off. If it's on, both channels mix into one and you hear the same sound, but that's not a problem synchronizing the headphones themselves.
You should also try clearing the Bluetooth cache on your phone, and to do so, find the Bluetooth system app in the app menu (you may need to turn on system processes) and click Clear cache, which will delete temporary files that may have caused the conflict.
⚠️ Note: Do not use third-party Bluetooth “enhancement” apps from Play Market stores. They often violate standard data protocols, leading to desynchronization. TWS headset.
Use of the Xiaomi Earbuds app
For owners of modern smartphones Xiaomi and Redmi with a shell MIUI or HyperOS available native app for headphone management, it allows not only to synchronize devices, but also to update their firmware.
Often, the problem of desynchronization is solved by updating firmware. Go to the application, plug in your headphones and check the "Update" section. If a new version is available, install it by putting your headphones in your case and connecting your phone to charge.
💡
Updating the firmware through the official application is the most reliable way to eliminate software bugs that cause channel desynchronization.
The app also has a headphone search and audio delay calibration feature for games, which helps to level the audio stream if you notice the sound lagging behind the video. Use automatic calibration for the result.
