Modern wireless headphones Xiaomi Airdots (also known as Redmi Airdots) have become a popular choice due to the affordable price and quality sound. However, users often face a situation when the devices stop working in pairs: sound comes from only one earphone, or the phone sees two different devices instead of one. This phenomenon is called desynchronization, and it is solved by forced merge of channels.
The process of reconnecting two Xiaomi Airdots headphones requires a precise sequence of actions. A mistake at any stage can lead to the procedure not being successful the first time. In this article, we will discuss in detail the algorithm of actions for models of different generations, including the S, 2S, Pro and newer versions, so you can quickly restore the headset.
Before you start to do complex manipulations, it's important to understand how these devices work, because the left earpiece is usually the wizard that connects to the smartphone, and the right earpiece connects to the left, and this master-slave bundle has to be restored before you connect to the phone, and if you try to connect them to the phone separately, the stereo effect won't work.
Why the headphones stop working in pairs
The main reason for this is a malfunction in the microcontroller software inside the headphones, which can happen after the battery drains one of the channels, the loss of the Bluetooth signal or the update of the smartphone firmware, sometimes devices simply forget each other and go into a waiting mode to connect to a new source.
Another common problem is contamination of charging contacts. If dust or oxides accumulate on metal areas inside the case or on the headphones themselves, the device may not charge until the end. Low battery charge often provokes unstable operation of the Bluetooth module, which leads to a break in communication between channels.
- 🔋 Low charge: One of the headphones discharged and left the pairing mode.
- 📡 Interference: Severe interference in the air interrupted the connection between devices.
- 📱 Bluetooth cache failure: Phone saved erroneous device profile data.
Also, you should consider the physical impact, drops or moisture can disrupt the antenna or internal contacts, in which case a software reset may not help, and you will need to diagnose the hardware part, but in 90% of cases the problem is solved by software reconnection.
⚠️ Warning: Before starting the procedure, make sure that both earbuds are at least 50% charged.If the battery sits down during the reset, the headset may go into deep recovery mode or stop responding to commands.
Preparation for the merger procedure
To do this successfully, you need to create clean connectivity conditions. The first step is to completely remove old profiles. Go to your smartphone's Bluetooth settings, search the Redmi Airdots or Xiaomi Airdots device list, and select "Forget Device" or "Disable."
After that, it is recommended to turn off Bluetooth on the phone completely, which will prevent an automatic attempt to reconnect during the setup, which can interfere with the synchronization process between the headphones themselves.
☑️ Preparation for synchronization
It is important to check that the charging case also has a sufficient charge. If you use older models where the indicators are only on headphones, make sure that the LEDs burn when removed. The lack of reaction may indicate the need to clean the contacts with alcohol or dry cloth.
Instructions: how to connect two headphones Xiaomi Airdots
There is a universal method that is suitable for most models of the Airdots and Redmi lineup. The essence of the method is to force both headphones to enter the search mode for each other without the participation of a smartphone. First place both headphones in the charging case and close the lid for 5-10 seconds to reset their state.
Take out both earbuds at the same time. They should start flashing the white light to signal the pairing mode. If the lights aren't burning or are burning red, put them back in the case and check the charge. Now you need to quickly press and hold the touchpads (or physical buttons) on both headphones at the same time.
Sequence of action:
1. Remove both earbuds.
2 Press and hold 5-10 seconds before switching off (red indicator).
3.Push again and hold 15-20 seconds until a series of blinks.When you hold the lights, they'll first turn red (switch off), then they'll flash white and red (mode), and they'll end up in a rare white flash mode, which means that the left and right channels have found each other, and you can turn on Bluetooth on your phone and search.
💡
If two devices are displayed in the Bluetooth list after the combination (for example, Redmi Airdots L and Redmi Airdots R), only one of them (usually L) will be connected automatically.
Features for different models (S, 2S, Pro, 3)
Different headphone modifications can have nuances in control. For example, in the Xiaomi Airdots S model, touch zones are less sensitive and the pressing should be more clear. Redmi Airdots 2S version often requires longer sensor retention to enter reset mode.
The Pro and 3 series models often feature quick pairing via a MIUI pop-up, but when desynchronized, this mechanism does not work. It is critical for them to perform a double reset: first turn off, then turn on and off again before starting the final pairing.
| Model | Type of management | Retention time | Indication of success |
|---|---|---|---|
| Airdots Basic | Sensor | 5-7 seconds | Fast blinking. |
| Airdots S | Sensor | 10-12 seconds | Double blinking. |
| Airdots 2 / 2S | Sensor | 15-20 seconds | Triple flashing. |
| Airdots 3 | Sensor/leg | 10 seconds. | Pulse. |
For models with a leg (like Airdots 3), the principle remains the same, but the touch zone is shifted to the bottom of the leg or the top edge. Be careful not to block the microphone holes with your fingers during prolonged pressing, although this is rarely affected.
What to do if the headphones do not connect
If the standard procedure failed and the phone still sees two devices or doesn't see them at all, try the "deep reset" method. Put the headphones in the case, close the lid and plug the case into the charger on the case. 10-15 Sometimes it helps to reset the residual charge of the capacitors.
Try connecting your headphones to another smartphone. If they work correctly on another device, the problem lies in your main phone's Bluetooth cache, in which case you need to clear the Bluetooth cache in the developer menu or perform a full reset of the network settings on the smartphone.
⚠️ Warning: Do not try to connect the headphones if one is flashing fast and the other is flashing slowly. This is a sign that they are in different modes. Repeat the procedure of turning off and on again, achieving synchronous blinking.
It is also worth checking whether the case has "remembered" the error state. Some users recommend leaving the headphones in a closed case without charging for 2-3 hours, which allows the power controller to completely zero out the temporary errors of logic.
The Secret Reboot Method
Customization and sound quality check
When you successfully combine the two channels, it's important to check the sound quality. Turn on the music with a wide stereo effect. Take the left and right earphones out of your ear, and the sound should remain monophonic, but when you return to the place, it will become stereo again. If the sound is completely lost when you remove one channel, then the synchronization is not complete.
Use the Xiaomi Earbuds app (or built-in MIUI settings) to check the charge level of each channel separately. If one earphone discharges much faster than another after reset, it may be that the battery has degraded, or it is constantly in active network search mode, which indicates a poor connection to the paired device.
💡
The quality of the channel combination is characterized by no delays, the same volume in both ears and the display of one device in the Bluetooth list.
