Modern users often face a situation where the wireless headphones Redmi AirDots or Xiaomi Mi True Wireless Earbuds stop working in pair. Instead of playing stereo, both devices can work independently, broadcasting only the left or right channel. This is not a failure, but a feature of the Bluetooth protocol, requiring proper synchronization between the master and the salvo.
You can restore a pair without going to a service center, and it takes a few minutes and requires a strict sequence of actions, and if you notice that the sound is only on one side, or the phone sees two identical devices instead of one, then the communication between the headphones is broken and you need to force the re-synchronization.
In this article, we will discuss all the steps of connection recovery for different versions of firmware. You will learn how to correctly reset, in what order to get the device from the case, and how to avoid common errors when pairing with a smartphone.
Reasons for the desynchronization of wireless headphones
Before we start to act, we need to understand why the problem is happening. Often users blame the hardware, even though it's a software glitch. Dissynchronization occurs when one earbud loses connection to the other, but continues to search for the playback device (smartphone), at which point both ears start to work as independent mono devices.
One of the common causes is that the right earphone sat down faster than the left earphone, it could shut down while the left one was still running, and once it was put in the case and then retrieved, the connection between the two might not automatically recover, and problems might arise after an Android or iOS update.
Affect the stability of the connection and external factors:
- π‘ Interference in the air: nearby Wi-Fi routers, microwave ovens or other radiation sources in the 2.4 GHz range can break the connection between the master and the plume.
- π Low battery power: At a critically low charge level, the Bluetooth module can run unstable, resulting in loss of synchronization data packets.
- π± Bluetooth cache on a smartphone: accumulated errors in the profile of the phone connection can prevent the correct handshake-process between gadgets.
Understanding the cause helps you choose the right strategy, so if the problem is caused by interference, you just need to change the location, and if the software failure is to blame, you need to completely reset the settings (Hard Reset) directly on the headphones themselves.
β οΈ Warning: Donβt try to pair your headphones with your phone until theyβre synchronized with each other, this will fix the error in the memory of your phoneβs Bluetooth module.
Preparation for reconnection
The success of the operation depends on the proper preparation. You can't just pull out your headphones and start poking them. First, you need to clear the connection history on your smartphone. Go to Bluetooth settings, find Mi True Wireless EBs on the list of devices. Basic_R or AirDots and select "Forget Device" or "Disable".
Then turn off Bluetooth on your phone completely. This is a critical step that is often ignored. While the phone is actively looking for devices, the headphones may try to connect to it in one-way mode instead of finding each other. Make sure that both earphones have enough charge - put them in a case for 10-15 minutes.
For the procedure you will need:
- π± Smartphone with Bluetooth module off.
- π§ Both Xiaomi AirDots headphones (left and right).
- β‘ Charging case with charged battery.
- ποΈ Free hands to manipulate touch panels.
βοΈ Preparation for synchronization
Only after these preparatory steps are completed can the immediate reset and reconnection procedure be proceeded, and ignoring the preparation minimizes the likelihood of success.
Step-by-step: how to connect two headphones
There's a universal algorithm that works for most AirDots, Redmi Earbuds, and Mi True Wireless models, and it's all about timing and consistency. First, remove both headphones from the charge case at the same time. If they start flashing red and white (or blue) colors, the process goes.
Leave them lying next to each other on the table for 10-15 seconds, at which point they are looking for each other. One of them (usually the right one) will become the main one, and the second will adjust to it. The indicator on the main device should start flashing slowly (about once per second), which means the standby mode of connection. The indicator of the second should go out or flash very rarely, signaling a successful bundle.
Now turn on Bluetooth on your smartphone and start looking for new devices. Only one device should appear on the list called Mi True Wireless EBs Basic (no L or R consoles). Press it to pair. If it goes well, sound will appear in both channels.

If the phone sees two devices with the same name, it means that the sync has not occurred. Delete both profiles and repeat the reset procedure.
In some cases, mechanical intervention is required to activate the mode (mating). To do this, after removing the headphones from the case, quickly press 5 times on the touch panel of each of them. This forcibly puts them in the pairing mode. Then put them again in the case, close the lid, wait 10 seconds and retrieve.
Hard Reset Method: Reset to factory settings
If the standard procedure doesn't work, you need to do a complete reset, which will return the headphone firmware to its original state by removing all temporary files and erroneous configurations. Hard Reset is the most effective solution for AirDots 1 and AirDots 2 models.
To perform the reset, remove the headphones from the case. Make sure the Bluetooth on the phone is off. Press and hold the touchpads on both headphones simultaneously for 20 seconds. You need to wait for the indicators to blink red several times in a row (usually 2-3 times) and then go out.
Once the lights are gone, put the headphones back in the case. Wait about 10 seconds for them to charge and fix the reset. Then pull them out again. Now they have to go into fast-blinking mode (phone search) after finding each other.
| Action. | Indication | The result |
|---|---|---|
| 5 sec retention | Voice Menu/Morgania | Entering the interface mode |
| 15-20 sec retention | Double blinking red | Reset settings (Reset) |
| Re-extraction | Fast flashing white | Connection readiness |
It's important not to let go too early. The reset timer doesn't start immediately, but after initial pairing or voice prompts. If you release the headphones at 18 seconds, the reset may not happen.
β οΈ Warning: While holding the sensors, the headphones can emit beeps or voice commands in Chinese or English.
Features of connecting different models Xiaomi
Xiaomiβs True Wireless lineup is extensive, and different models can have nuances in control. For example, in AirDots 3 or Redmi Buds 3, touch control can be replaced by mechanical tapping. In such cases, the reset algorithm changes: instead of holding the sensor, you need to quickly press the touch area 5 times.
For active noise cancellation (ANC) models, the procedure may require the use of the Xiaomi Earbuds or Mi Home app. The app often has a "Hearbud Reset" or "Hearbud Search" feature that automates the process. If you have an advanced model, check for firmware updates through the app.
Differences in indicators also play a role:
- π΄ Red glow: usually means low charge or charging process in a case.
- βͺ White Blinking: Device or pairing search mode.
- π΅ Blue blinking: characteristic of older firmware versions or specific regions (Global vs China version).
Differences between Chinese and Global Version
If you have a Pro or Premium edition, make sure you use the original case. Cases from different models may not correctly transmit the wake-up signal, which will prevent the headphones from syncing when retrieving.
Solution: if one headphone is not working
When you've had one earpiece running after all the manipulations, you need to pay attention, and that often means that one device is stuck in mono-op mode, so try putting a working earpiece in your case and leaving the one that's not working outside, and then pull out the one that's working and try to connect them again.
Sometimes cross-connecting helps, connect your headphones to another smartphone or tablet, and if the stereo is working on another device, then the problem is in your main phone's Bluetooth cache, so on Android, you can try clearing the Bluetooth cache through the developer menu or special applications.
Check the charging contacts. If one of the headphones is not charging in the case (the indicator on it does not light up red when placed in the socket), it could completely discharge and go into deep sleep. Wipe the contacts with alcohol and press the earphone in the case for a minute to "push" the charge.
If nothing works, one of the headphones' Bluetooth modules may have failed, in which case the software methods are powerless and a replacement device is required.
β οΈ Warning: Do not keep your headphones empty for a long time. the lithium polymer battery may swell or lose capacity, which will make it impossible to turn on.
Prevention and proper operation
To keep the desynchronization problem from returning, it's important to follow the rules of operation. Always put the headphones in the case after use. Don't just leave them on the table, which drains the battery and keeps the Bluetooth module in active search mode, which increases the risk of failure.
Regularly clean contacts in the case and on the headphones themselves. Oxidation of contacts leads to the fact that the headphone in the case does not charge or turn off, but continues to search for the network, consuming resources.
Basic rules of care:
- π§Ή Cleanliness: once a month wipe the speaker mesh and contacts with a soft dry cloth.
- π Charge: Do not let the headphones run completely for a long time. If you do not use the headphones for a month, charge them.
- πΆ Updates: follow the release of new versions of the software through the official application.
