Modern wireless headsets offer incredible freedom of movement, but sometimes users face technical difficulties in the initial setup. The question of how to connect two Xiaomi Airdots headphones at the same time often arises for owners who are trying to activate the device for the first time or after resetting. Proper synchronization between themselves and the smartphone is a key step on which the stability of the connection and sound quality depends.
Many beginners make the mistake of trying to pair each earbud separately through a Bluetooth menu, which leads to channel desynchronization, resulting in sound coming from only one speaker, or devices can't see each other. TWS-The True Wireless Stereo system will help you avoid unnecessary manipulation and save you time. In this article, we will discuss in detail the algorithms of actions for all current versions of headsets.
The principle of operation of TWS-headsets Xiaomi
True Wireless Stereo technology means that the left and right headphones connect to form a single network and then broadcast the sound to an external device, usually led by the right-hand module, which takes on the role of a bridge to transmit data, and if you try to connect them separately, the system will perceive this as two different mono-devices, which will disrupt the stereo effect.
To work properly, Xiaomi Airdots headphones must first “find” each other inside or outside the case, which occurs automatically when they are removed from the charging case unless they have previously been tightly tied to another source. Synchronization between modules is a priority process that must be completed before pairing with the smartphone.
Sometimes users confuse standby mode with pairing mode: in the normal state, the headset just waits for the signal, and to combine the two parts into a stereo pair, the required sequence of actions is required.
Why are the headphones unsynchronized?
Preparation for pairing: cleaning the list of devices
Before trying to combine two Xiaomi Airdots headphones into a single system, you need to do preparatory work on the side of the smartphone. If your headphone profile is already stored in the phone’s memory, but they are not working correctly, the old profile should be removed, which will eliminate MAC address conflicts and force the system to recreate the connection from scratch.
Go to your mobile device’s Bluetooth settings and find a Xiaomi AirDots record (or a specific model, such as Redmi Buds) in the list of available or saved gadgets. Click on the gear icon or hold your finger on the name, then select the “Forget” or “Disable” option.
The next step is to completely discharge or programmatically reset the headphones themselves, and place them in a charge case and leave them there for a while so that they go into deep sleep, which helps clear the temporary error buffer inside the headset microcontrollers.
💡
Before starting the procedure, make sure that the contacts on the headphones themselves and inside the case are clean. Oxidation or dust can prevent full charge, which will prevent one of the modules from turning on in time.

Algorithm for connecting two headphones at the same time
There is a proven method to force the left and right channels to synchronize before connecting to the phone. First, remove both earphones from the charger case at the same time. They must automatically turn on, as the light indication will tell you. If this does not happen, press and hold the touch zones on both modules for 5 seconds.
Now you need to start pairing. Most Xiaomi Airdots models require (long pressing) touch panels on both headphones at the same time. Keep them pressed for about 5-7 seconds until the indicators start flashing white at a certain frequency. This is a signal that the modules are looking for each other to create a stereo pair.
Once the lights on both devices catch on fire or blink, put them back in the case for a few seconds, and then pull them out again, at which point one of the headphones (usually the right one) should blink quickly, and the other should stop blinking or blinking less often, which means they are connected together. You can now turn on Bluetooth on the phone.
| Model | Search indication | Indication of connection | Retention time |
|---|---|---|---|
| Xiaomi Airdots 1 | White flashing | The indicator is gone | 5-7 seconds |
| Redmi Airdots S | Red and white. | Only one flashes. | 7 seconds |
| Xiaomi Airdots 2 | White flashing | Indicators off | 5 seconds |
| Redmi Buds 3 | White fast. | Slow blinking | 3-4 seconds |
⚠️ Note: If one earphone flashes after extraction from the case and the other is silent, then the stereo is not created.
Solving the problem of desynchronization (Hard Reset)
In situations where standard methods don’t help and the phone sees two devices with the same name (e.g. Mi True Wireless EBs). Basic_R And L, requires a hard reset, and this procedure brings the headphones back to the factory settings, removing all previous ones, and you need to do it carefully, and you need to do it with the timings.
Place both earbuds in the charge case, but don't close the lid at once. Make sure they charge (red lights burn). Then press and hold the touch zones on both earbuds simultaneously for 20 seconds. The indicators should flash red several times, confirming a successful reset.
After a red flash, remove the headset from the case. Now they're in factory testing mode and ready for initial pairing. Turn on Bluetooth on your smartphone and find the device. Now the list should only show one gadget, which indicates a successful channel integration.
💡
Hard Reset is a universal solution for 90% of the problems with the desynchronization of the left and right channel in Xiaomi Airdots.
Features of connecting different versions of Airdots
Different generations of Xiaomi headsets have their own nuances in management, for example, the first version of Airdots often required manually initiate a search, while newer models such as the Airdots 2 or Redmi Buds 3 Lite do this automatically when opening a case (if the Fast Pair function is implemented).
For touch-controlled models, it is important not to confuse short presses (pause/playback) and long presses (assistant call or reset). When trying to synchronize two Xiaomi Airdots headphones at the same time, it is critical to hold your fingers until the color of the indicator changes. Early vacation can interrupt the process of entering pairing mode.
Some advanced models support the Xiaomi Earbuds or Mi Home app, which allows you to check the charge of each module separately and update the firmware. If one of the headphones is discharged more than the other, the system can block the creation of a stereo pair to save energy, so it is better to charge the case to 100% before connecting.
Can I use the headphones one at a time?
Frequent errors and ways to fix them
One of the common mistakes is to try to plug the headphones in when they're in power saving mode, and if the lights don't light up when they're removed, maybe the protection worked, and then you put them in the case for 10 seconds, then you pull them out and you start pairing them right away without waiting for them to shut down.
Users also often ignore the distance between the devices. When you first synchronize two Xiaomi Airdots headphones with each other, they should be in close proximity (no further than 10-15 cm from each other). If you hold them in different hands with a wide spread, the signal may not “grab” the first time.
Another problem is interference from other Bluetooth devices or Wi-Fi routers, and if there is a lot of active electronics in the room, the search process may take longer or be interrupted, and it is recommended that you set up indoors with a minimum number of wireless signal sources.
⚠️ Warning: Do not try to connect your headphones to your phone while the lights on them flash quickly. First, wait until they stop blinking or go into slow blinking mode, which means that the left and right modules are successfully connected.
