When one of Xiaomi’s headphones stops working or they don’t connect to each other, many wireless headset owners are familiar with. Instead of the expected stereo sound, the user hears silence or monophone crackling, which completely disrupts the process of listening to music. Most often the problem lies not in the hardware failure, but in the software dissynchronization of the right and left modules, which should work as a unit.
Reinstatement of operational capacity TWS-A True Wireless Stereo usually requires a series of sequential actions, which can be a complete cleanup of the connection history in a smartphone, a forced reset of the device itself, or a reboot of the Bluetooth module. It is important to understand that the algorithms of different models, whether it is Redmi Buds or Mi True Wireless, may have their nuances, but the basic principles of communication recovery remain similar.
In this article, we will discuss all possible causes of failure in detail and offer proven methods for eliminating them: you will learn how to correctly reset, update the firmware through the Mi Wear application and diagnose the state of the battery, which often becomes the culprit of unstable work.
The main reasons for dissynchronization TWS-headset
Before we start to actively restore, we need to understand the nature of the conflict that has arisen, and when the left and right earbuds stop seeing each other, they go into independent mode, which means that each device tries to connect to the sound source separately, ignoring its "partner," a behavior that is often observed after the headset has been connected to another smartphone or tablet.
Another common reason is the different charge levels in the case and the modules themselves. If one of the headphones was discharged to zero and was in this state for a long time, its power controller could go into deep sleep, in which case, even after installing in the charging case, the device may not show signs of life or not be switched on simultaneously with the other module.
⚠️ Attention: A common mistake is to try to plug headphones in without removing them from the case or activating the pairing mode.Make sure that protective films are removed from the contact areas if the headset is new.
Software failures in the smartphone operating system also play a role: Updating Android or iOS can change Bluetooth security protocols, which causes old cache entries to stop being processed correctly, in which case the system sees the device, but can not transmit an audio stream to it or connect channels with each other.
Preparing for Recovery: Cleaning Connection History
The first and most important step in solving this problem is to completely clean up the pairing history, so as long as the smartphone remembers the old settings, it will try to connect using a previously stored but now incorrect protocol, you need to go to the Bluetooth settings of your mobile device.
Find your model in the list of available devices, such as Redmi AirDots or Mi True Wireless Earbuds. Click on the gear icon or the "i" icon next to the name and select the option "Forget the device" or "Cancel pairing." This procedure should be repeated if there are several entries with the same name in the list.
Once the devices are removed, it is recommended to turn off Bluetooth completely on the smartphone and turn it on again, which initiates a search for new devices and clears the temporary cache of the radio module, only then you can proceed to manipulate the headphones themselves.
☑️ Checklist of preparations
Methods of complete reset (Hard Reset) headphones
If a simple reconnection didn't work, you need to reset completely, and it will return the headset to factory status, erasing all temporary files and synchronization errors, and the reset method depends on the specific model and the physical button on the charging case.
For models with a button on the case (e.g. Mi True Wireless Earphones 2): place both headphones in the case, leave the lid open. Press and hold the function button on the case case case case for 15-20 seconds. The indicator should flash a certain color (often white or red), signaling a reset.
For models without a button (e.g. Redmi AirDots, Earbuds Basic): This uses touch control. Remove the headphones from the case. Quickly press 5 times on the touchpad of each earphone. The indicators should blink, then the devices will turn off. Then place them back in the case and re-extract them for automatic pairing.
⚠️ Warning: During reset, do not remove the headphones from the case before the time if the instruction requires them to be inside.
After reset, the headphones must go into pairing mode (the indicators flash). At this point, it is important not to connect them directly to the phone. Give them 10-15 seconds to find each other. Usually the right earphone (main) finds the left one, and the blinking of one of them stops or changes frequency.
What if the reset doesn’t help the first time?
Diagnostics through Mi Wear app and software update
Modern Xiaomi ecosystem devices require the use of proprietary software to work correctly. Mi Wear (or Xiaomi Earbuds for older models) allows you not only to track the charge, but also to update the internal firmware of headphones. Often synchronization bugs are fixed in patches.
Connect the headset to your smartphone and open the app. If the devices see each other but only sound from one, check the Software Update section. If a new version is available, be sure to install it by putting the headphones in your case and plugging in the charger.
You can also calibrate the touchpads and check the microphones in the app. Sometimes the software failure is that the erroneously system considers one channel inactive. Resetting the settings within the application can help redistribute roles between channels.
| Model headphones | Type of discharge | Indication of success | Annex |
|---|---|---|---|
| Redmi AirDots | 5 touches of sensor | Red flashing | Mi Wear |
| Mi True Wireless 2 | Case button (15 seconds) | White flashing | Mi Wear |
| Xiaomi Buds 3T | Case button (10 seconds) | Orange light | Xiaomi Earbuds |
| Haylou GT1 | 4 touches of the sensor | Red and blue. | Haylou |
💡
Using an official application is the only way to update the firmware of the Bluetooth module, which often solves compatibility problems.
Problems with charging and contact
One of the most common, but often ignored, causes of out-of-synchronization is poor contact, so if one of the headphones doesn't charge in the case, it discharges faster and shuts down while the other one is still running, which creates the illusion of losing communication.
Carefully inspect the contact areas on the headphones themselves and inside the case, often accumulating earwax, dust or oxides that prevent current from passing, wipe the contacts with a dry lilaless napkin or cotton swab lightly soaked in alcohol.
Also check if the magnets fit tightly, and if the case is deformed from a fall, the earpiece may not be fully immersed in the socket, in which case you can gently press the contacts (if the design permits) or use a small piece of insulation at the bottom of the socket to lift the earpiece.
💡
To clean the contacts, use isopropyl alcohol, it quickly evaporates and does not leave moisture that could damage the electronics.
Radical methods and reconnection
If standard methods fail, you can try a blank slate method that turns off all wireless interfaces: turn off Bluetooth, Wi-Fi and NFC on your smartphone; delete the headphone profile; turn off the phone itself.
Do a full Hard Reset, as described above. Don't turn your phone on, put your headphones in your case, close the lid, and wait. 1-2 Then pull them out. They should start blinking, looking for each other.
Only after you’ve made sure both lights behave the same way (or one stops blinking to become a master device), turn on Bluetooth on your phone and search.
⚠️ Attention: If none of the methods worked and the headphones are still out of sync, the Bluetooth module in one of the headphones probably failed.
