Xiaomi's budget audio users often find themselves in a situation where, after extracting from a case, one of the headphones stops playing or the sound is only in one ear. This is a classic sign of desynchronization, where the left and right channels lose communication with each other and work independently. Instead of a stereo pair, you get two mono devices, which makes listening to music or watching movies extremely uncomfortable. Recovery requires a specific sequence of actions known as reconnection or resynchronization.
The process of reconnecting between modules does not require a connection to a phone or computer, since it occurs at the hardware level of the headphones themselves. You need to initiate the pairing mode manually, forcing the devices to βfindβ each other. In this article, we will discuss in detail the algorithm of actions for the models of Redmi AirDots, AirDots 2 and AirDots 3, and also consider the reasons why the Bluetooth protocol malfunctions.
Before you start complex manipulations, make sure that the problem lies in the software failure, not in a dead battery. Often users try to connect devices, forgetting that both modules require sufficient charge to work consistently. If the indicators flash dimly or do not light up at all, first place the gadgets in a charging case for 15-20 minutes.
Reasons for desynchronization of headphones Xiaomi
Understanding the causes of a failure helps prevent it from happening again in the future. The main reason is that the Bluetooth protocol works in budget chips, where one headphone acts as a master and the second as a slave device. If communication between them is interrupted, the system cannot always automatically restore the master mode without user intervention.
- π The battery discharge of one of the modules is below the critical level, which causes its spontaneous disconnection and a pair rupture.
- π± Failure of the Bluetooth adapter of the smartphone after updating the operating system or conflicting applications.
- π Flawed fit of contacts in the charging case, because of which one headphone was not charged and went into a deep sleep.
- π Signal interference in places where a large number of wireless devices (offices, public transport) are congested).
β οΈ Attention: If you haven't used your headphones for a long time, they might have gone into deep sleep, so just removing them from the case doesn't activate them -- you need to force them to go on with a long press.
Also, consider the physical wear of the contacts. Metal quilts can oxidize over time or accumulate earwax, which prevents normal charging and data transmission when in the case. Regular cleaning of contact areas with dry soft cloth helps to avoid problems with automatic mating.
Preparation for the interface procedure
Before you start the recovery process, clear the connection history on your mobile device. This is a critical step, as the phone may be trying to connect to an old, incorrect profile of the device. Go to your smartphone's Bluetooth settings, search the Redmi AirDots or Mi True Wireless EBs list, and select the "Forget Device" or "Delete" option.
Once you delete your profile, make sure you turn off Bluetooth on your phone completely, which will prevent you from automatically connecting while you set up your headphones. Now that the external ones are off, you can move on to manipulating the headsets themselves. Make sure you're in a confident reception zone, away from powerful sources of radiation, such as microwave ovens or routers.
It is important to distinguish between models, as the controls may differ: In the early versions of AirDots, manual buttons are used, while newer models such as AirDots 3 or Basic 2 use touch control. Mechanical buttons require physical pressing, sensors require touching or prolonged finger retention in the touch zone.
βοΈ Preparation for discharge and pairing
How to connect Redmi AirDots to each other
There is a universal method that is suitable for most models of the line of Redmi and Mi True Wireless. The essence of the method is to force both headphones to search for a pair at the same time. Take both headphones from the case and make sure that they are turned off (the indicators do not burn). If they are on, turn off their long press.
Now, hold the touchpads (or buttons) on both headphones at the same time. Hold them in this position for about 5-7 seconds until the indicators turn red. Don't let your fingers go right away! Keep holding on for another 10-15 seconds. You'll see the lights go out and then start flashing white. It's the white blink that signals that the devices have entered pairing mode with each other.
Sequence of action:
1. Remove both earbuds.
2. Press the buttons/sensors for 5 seconds (off).
3.Never let go, keep another 15-20s until double blinking.
4. wait until one earphone stops flashing (he became a master).When the lights start flashing white a lot, release the headphones and put them on the table next to each other. One of them (usually the right one) should stop blinking or blinking less often - which means that he has become the main one and is now looking for a second headphone. The second headphone will continue to blink quickly, waiting for the connection. After a few seconds, the blinking should stop or go into the mode of rare waiting for a connection to the phone.
Setting up the connection to the smartphone
After successfully synchronizing left and right, the headphones are ready to connect to the sound source. Turn on Bluetooth on your smartphone and start searching for new devices. One name should appear on the list of available devices that corresponds to your model, for example, Redmi AirDots or Mi True Wireless EBs Basic.
If the list shows two identical devices, it means that the pairing procedure between the headphones was not successful. In this case, you need to repeat the procedure described above, paying special attention to the synchronicity of the button presses. Sometimes it takes several attempts to match the timings perfectly.
| Indication | Meaning | Action. |
|---|---|---|
| Red is burning. | Charging. | Leave it in the case. |
| White flashing fast | Couple-searching mode | Wait for the connection |
| White rare flashing | Waiting for connection | Connect to Bluetooth |
| Blue flashing | Combination coming. | Process automatic |
Once you click "Plug" on the phone menu, the headphones can flash blue, which will confirm that you've made a successful connection. You can now turn on music and check the stereo effect. If only one ear has sound, check the channel balance in your Android or iOS device's special features settings.
Solving problems with Redmi AirDots 3 and Pro models
The third-generation models and the Pro version have some differences in the logic of touch control. These devices often use a more complex touch recognition algorithm, which can lead to false positives or, conversely, ignoring commands when trying to reset. For Redmi AirDots 3, the reset procedure can differ in the duration of retention.
If the standard 20-second method doesnβt work, try the alternative: turn on the headphones, then turn them off, and immediately after turning them off (while theyβre still in your hand) start counting down to reset mode. Some users have noted that itβs more effective for these models to keep the headphones in the case when performing the reset if the case design allows you to press sensors through the open lid, although this is not the manufacturerβs standard recommendation.
β οΈ Note: On models with active noise reduction (ANC) Resetting can also bring the noise maker back to factory settings. Make sure that once connected, you reset the noise reduction mode again via the Mi Home or Xiaomi Earbuds app.
In the event that one earphone does not see the other at all, even after multiple reset attempts, there may be a hardware malfunction of the Bluetooth module inside one of the cases, which may be due to moisture or impact, in which case the software methods are powerless, and diagnostics are required in the service center.
