Owners of popular Xiaomi and Redmi wireless headsets often face a situation where devices stop working as a single stereo system.This happens when the right and left headphones lose communication with each other and start playing sound independently or only one of them. This problem is known as desynchronization, and it can occur after a discharge, smartphone update or software failure in the operating system.
To restore normal operation, you need to perform a re-pairing procedure that will force the gadgets to find each other and join together in a pair, which requires no special equipment and takes only a couple of minutes if you follow the algorithm clearly, and it is important to understand that in most cases the problem lies not in hardware failure, but in the software mismatch of Bluetooth modules.
In this tutorial, we will take a look at all the steps to restore connection, from cleaning the history of connections on the phone to hard resetting the settings of the headphones themselves, learn to recognize the status indicators and understand how to correctly interpret the flashing of LEDs. A competent approach will allow you to avoid a repeat of the situation in the future.
Reasons for the desynchronization of headsets
Understanding the cause of a failure helps you find a solution faster and prevent it from happening again. Most often, desynchronization occurs when one of the headphones discharges faster than the other, in which case the master module (usually the right one) may lose communication with the slave, and when placed in the case, they do not have time to restart the connection protocol correctly.
Another common reason is third-party interference: If your headphones have previously been connected to another phone or tablet, they may try to automatically connect to the latest known gadget when extracted from the case, creating a conflict in which the left and right channels search for different signal sources.
Programmatic reasons include:
- 📱 Update of the smartphone operating system that changed Bluetooth drivers.
- 🔄 Failure of the firmware of the headphones themselves after full discharge of the battery.
- 📡 Interference from other wireless devices operating at 2.4 GHz.
Sometimes the problem is the oxidation of the contacts in the charging case. If the headphones are not tightly attached to the contacts, they may not charge to the end or go into mating mode when the lid is closed. Always check the cleanliness of the contacts before starting the recovery procedure.
Preparation for the discharge procedure
Before you start the synchronization process, you need to perform a number of preparatory steps, ignoring this step can lead to the fact that the procedure will not work the first time, the main goal of preparation is to completely clear the memory of the smartphone from the old connection settings.
Take your smartphone and go to Bluetooth settings. Find your headphone model (e.g. Mi True Wireless Earbuds Basic 2 or Redmi AirDots) on your device list. Click on the gear icon or select Forget the device/Delete. If there are duplicates of the same name, delete them all.
⚠️ Warning: Do not turn off Bluetooth on your phone immediately after removing the device. Leave the module active, but make sure the phone does not attempt to automatically connect to the headphones while they are in the case.
Once removed from the list, you need to completely turn off Bluetooth on your smartphone.This is a critical step, as background search can prevent the headphones from entering pairing mode. It is also recommended to close all applications that can use audio, such as music players, YouTube or instant messengers.
☑️ Checklist for synchronization preparation
Make sure the headphones are at least 30-40% charged. If the battery is too low, the lights may flash incorrectly, or the devices will turn off during repiring. Put them in the case for 10-15 minutes if there is any doubt about the level of charge.
Hardware reset of Xiaomi headphones
The most effective way to get your headphones to forget old settings and find each other again is to perform a hardware reset. The technique may vary slightly depending on the model, but the basic principle remains the same for most Mi True Wireless devices.
Put both earbuds in the charge case. Make sure they're in their seats and the magnets are pulling them in. The headphones should light up red to signal the start of charging. If the lights aren't on, move the headphones to make contact.
Further, the algorithm of actions depends on the presence of a physical button on the case:
- 🔘 Case with button: Press and hold the functional button on the case case case case during 10-15 The indicator should start flashing white and then go out or change the frequency of blinking.
- 🖐 Case without a button: You have to use the touchpads of the headphones themselves. Remove them from the case, wait for them to turn off (if they burn), then press and hold the touch zones on both headphones simultaneously for a period of time. 5-7 seconds before the indication appears.
There is a universal method for models without a button on the case that is often overlooked: Put the headphones in the case, close the lid and wait 10 seconds. Then open the lid and quickly press the touchpads on both headphones at the same time 5 times. This action initiates reset mode on many Redmi AirDots models.
What do the color of the indicators mean?
Re-pairing (re-pairing)
Once the reset is done, the headphones go into standby mode, at which point they have to find each other before you try to connect them to the phone, which is a key point of the whole instruction manual.
Remove both earbuds from the case at the same time. Don't touch them for a few seconds. They're exchanging service signals. You'll notice that the lights on them will flash. At first, they can flash quickly and independently, but after 5-10 seconds, one of them (usually the right one) should stop blinking or blinking less often, and the other (left) should keep looking.
In an ideal scenario, the following will happen:
- The indicators on both headphones flash quickly white.
- After a few seconds, the blinking on one of the headphones stops or becomes very rare (once every few seconds).
- This means that the stereo is built and the device is now ready to search for the phone.
Just make sure your headphones are synchronized, turn on Bluetooth on your smartphone. Start searching for new devices. Only one name of your headset should appear on the list. If you see two identical names (for example, two "Mi True Wireless EB Basic R"), then the synchronization between the headphones has not gone through, and you need to repeat the reset procedure.
Diagnosing Connection Problems
Even if you follow all the instructions, there may be nuances. Different Xiaomi and Redmi models have their own characteristics of the behavior of indicators. Below is a table that will help decipher the state of your headphones.
| Status of the indicator | Probable cause | Action. |
|---|---|---|
| It burns red all the time. | Low battery charge | Put it in the case for charging. |
| Blinks white (both) | Couple search mode or dissynchron | Waiting for union or resetting |
| Blinks red and white | Connection error or discharge | Check the contacts in the case |
| It's not burning at all. | Deep discharge or breakdown | Leave in the case for 30+ minutes |
If the phone sees the headphones but writes “Unconnected” or “Pairing Error,” try clearing the Bluetooth cache on Android. Go to Settings → Apps → Show System Processes → Bluetooth. Select Storage and click “Clear Cache.” After that, restart the smartphone.
Sometimes forgetting the device, not just on your phone, but on other gadgets, helps. If your headphones were connected to a laptop or tablet and Bluetooth is on, they can intercept the connection. Turn off Bluetooth on all the surrounding devices except the one you use to set up.
⚠️ Warning: If one earbud is working and the other is silent even after synchronization, try putting a working earbud in the case and leaving the one that is not working outside.
The Mi True Wireless and AirDots models
Xiaomi’s lineup of wireless headphones is extensive, and each series has its own features. For example, Mi True Wireless Earphones 2 models often have a button on the case, which makes reseting easier. At the same time, budget Redmi AirDots require precise coordination of touch panel presses.
The Mi True Wireless Earbuds Basic 2 series is characterized by the problem of having headphones stuck in mono mode, which is treated by long-term (up to 30 seconds) sensor retention when in the case, and some users note that removing the headphones from the case helps not at the same time, but with an interval of 2-3 seconds after reset.
Active noise cancelling (ANC) models may require an additional step. After reset, they may not connect automatically, in which case you need to manually activate pairing mode on the earphone itself, quickly pressing the sensor 3 times when the indicators go out after reset.
💡
If a standard reset doesn't work, try discharging the headphones to zero. Leave them out of the case for hours or days until they completely stop responding. Then put them on charge and try the procedure again - this often resets the power controller.
If you have the option to connect them to Mi Wear or Xiaomi Earbuds (for supported models), check for updates. Sometimes the manufacturer releases patches that fix the connection stability.
Prevention and proper operation
To avoid the problem of desynchronization, you should follow certain rules of use. First of all, try to discharge the headphones evenly. If you use only one earphone for calls, periodically change them so that the charge balance is not disturbed critically.
Always put your headphones in your case immediately after use, even if you plan to put them on in 5 minutes, which ensures that they always start with a clean slate and undergo the initial handshake procedure inside the case. Chaotic storage in your pocket without a case leads to accidental taps and discharge.
Key recommendations for care:
- 🧹 Regularly wipe contacts with alcohol or dry wipe.
- 📦 Do not store a case with headphones near powerful sources of magnetic fields.
- 🔋 Do not allow a full deep discharge for a long time.
Observing these simple rules will prolong your life. TWS-And you can have a stable stereo sound, and remember, electronics love order, and the right sequence of things when you connect is the key to success.
💡
The main secret to success is to always reset and repire away from other well-known Bluetooth devices so that the headphones connect to each other, rather than to a phone or speaker.
