Owners of popular Xiaomi wireless headphones often face a situation where the device stops working correctly after a smartphone system update or a spontaneous communication break. If your Xiaomi Airdots 2 stopped syncing with each other, one earphone is silent, or the phone does not see the headset in the list of available devices, a standard power outage here will not help.
The only effective solution is 95% of the time, forced resetting to factory settings, which clears the internal memory of the Bluetooth module, erases all stored pairs, and returns the firmware to its original state. Below, we will discuss in detail the algorithm of actions that will allow you to resuscitate your headset without going to the service center.
Before starting the procedure, make sure that there is enough charge in the case and on the headphones themselves, since the indicators will flash more actively than usual during the reset process. It is also important to understand that after completing all the steps, you will have to re-pair the phone, as if you just took the device out of the box.
Diagnostics of synchronization problems TWS-headsets
Before we take any drastic measures, we need to make sure that the problem is a software failure, not a hardware breakdown. Often users confuse channel desynchronization with battery discharge or contact contamination. If the right-hand-held Xiaomi Airdots 2 headphone (which is a master device) does not transmit a signal to the left, or the sound is only on one side, this is a classic sign of loss of communication between modules.
It is important to note that TWS-The True Wireless Stereo headphones work in a pair where one device is the lead and the other is the follower, and when the firmware fails, this hierarchy is broken, and the gadgets stop recognizing each other. In some cases, the phone can see two devices with the same name, which also requires immediate intervention.
For accurate diagnosis, pay attention to the behavior of LED indicators. If they do not blink or flash at an uncharacteristic frequency when extracted from the case, this may indicate oxidation of contacts. In this situation, resetting may not help until you clean the contact areas with an alcohol napkin.
Preparation for the resetting procedure
Good preparation is key to a successful recovery of the gadget. Mistakes at this stage often lead to the procedure not being completed, and the headphones remain on standby. The first thing you need to do is completely remove old records about your headphones from the memory of your smartphone, a critical step that many people ignore.
Go to your phone's Bluetooth settings, search the Xiaomi Airdots 2 (or Airdots BASIC 2) list, and click "Forget Device" or "Disable." Make sure there are no more entries with similar names in the list of paired devices. If the phone keeps trying to connect automatically, temporarily turn off the Bluetooth module on the smartphone.
💡
Before reset, put the headphones in the case for 5-10 seconds so that they are guaranteed to go into charging mode and turn off.
Also check the case charge. If the indicator on the case doesn't light up when you open the lid, set it on charge for at least 15 minutes. Low charge can cause the headphones to simply turn off during the reset and have to repeat the procedure again. Make sure that the headphones themselves sit tightly in the sockets and the magnets pull them.
Step-by-step: how to reset Xiaomi Airdots 2
The reset process itself on the Airdots 2 is done mechanically through the touchpads. There's no physical Reset button like some other models, so accuracy and timing are important. Place both earbuds in the case, then remove them at the same time.
Wait for the lights to go on. Now you have to press and hold the touch zones on both headphones at the same time. This is the hardest part, because it requires synchronization. Keep your fingers on the sensors for about 5-7 seconds until the lights start flashing red, and then let go.
☑️ Airdots 2 reset algorithm
Once the lights flash red, put the headphones back in the case and close the lid. Wait 10 seconds. Now pull them out again. You should see that the lights have started flashing white (or white with red), which signals pairing mode. This means that the reset has been successful and the headset is ready for a new connection.
Table of indicators: decoding of signals
Understanding color display helps control the recovery process, different blinking modes tell the user about the current state of the device, and below is a table of main signals for the Xiaomi Airdots 2 model.
| Color of indicator | Mode of work | User action |
|---|---|---|
| Red (constantly) | Charging's coming. | Expect full charge. |
| Red (flashing) | Low charge/Dumping mode | Charge or release sensors |
| White (blinks) | Interconnection mode | Search for the device in Bluetooth |
| White (blinking fast) | Searching for a second headphone | Put it in the case and repeat the reset |
| Blue (blinks) | Connected to the phone. | We can use it. |
Note that if the indicator continues to flash white quickly after reset and does not go into the search mode for the second headphone, then the synchronization between the left and right channel has not recovered, in which case the procedure should be repeated, paying more attention to the simultanic pressing of the sensors.
💡
Successful reset is confirmed by the transition of indicators to fast white flashing mode 10 seconds after extraction from the case.
Solving common errors in resetting
Even with the right instructions, there can be nuances, like if one earbud flashes and the other doesn't, which often happens if one of them is more severe than the other, and then leave the headphones in a closed case for 30-40 minutes, even if the lights show full charge.
⚠️ Warning: Don't try to reset if the headphones are connected to the phone at this point.This will lead to a conflict of commands and no reset will occur.Always start the procedure with Bluetooth off on your smartphone.
Another common problem is phantom connections. The phone can remember old settings and try to connect to one of the headphones, ignoring reset mode. To avoid this, clear the Bluetooth cache on Android devices through the developer menu before you start manipulating it, or simply restart the smartphone after you delete the device.
If after three reset attempts, Xiaomi Airdots 2 headphones still don’t connect to a stereo pair, it may be the hardware part of one of the modules that is the problem: check if the microphone and touch control on each headphone work separately, connecting them to the phone as a mono device.
Proper pairing after discharge
After a successful reset, the initial setup phase begins: turn on Bluetooth on your smartphone and start searching for new devices. The list should include one device called Airdots 2 (or Mi True Wireless EBs Basic 2).
Click on the name to connect. At that point, the headphones should stop flashing and light up blue (or go out, depending on the firmware version). The sound signal in the headphones will confirm the successful connection. Now check the stereo mode by turning on the music.
What to do if your phone sees two Airdots 2 devices?
To improve sound quality and connection stability, it is recommended to step away from the phone at a distance of 1-2 meters after connecting and check if the signal is interrupted. It is also worth checking the sensors: a single touch usually puts the track on pause, and a double touch usually switches tracks or calls a voice assistant.
Failure prevention and headset care
To minimize the need for future resetting, you should follow simple rules of operation: Regularly wipe the contact areas on the headphones and inside the case with dry soft cloth. Dust and earwax can create insulation, which causes the headphones to not charge and go into a deep discharge.
Don’t let the battery run completely to zero for a long time. Lithium polymer batteries used in Xiaomi Airdots 2 degrade if stored long enough to run out. If you don’t plan on using the headphones for a month or more, charge them up to 60-70% and store them off.
⚠️ Warning: Avoid using headphones in extremely low or high temperatures. Overheating or hypothermia can cause a temporary Bluetooth controller failure that is eliminated only after returning to room temperature and resetting.
Update your smartphone software periodically. New versions of Android and iOS often include security patches and improvements in stability with Bluetooth protocols, which have a positive effect on the connection with peripherals.
