Sometimes even the most reliable gadgets start to behave unpredictably, and wireless headphones are no exception. If your Xiaomi Airdots 2 stop syncing with each other, the phone does not see the device or the sound is interrupted, most likely a complete reset is required. This procedure returns the headphones to factory settings, removing all temporary errors and old connection profiles.
In this article, we will take a look at how to perform a hard reset for your model, not only the standard algorithm of actions, but also the nuances that users often miss, which leads to repeated problems. Understanding the physical principles of sensors and buttons will help you avoid errors in the process.
Before we get into action, we need to make sure that the problem is really a software failure, not a battery that's run out. Setting reset is a powerful diagnostic tool that often solves 90 percent of communication problems. Let's go through all the steps in as much detail as possible so you can bring your gadgets back to life.
Preparation of the device for the discharge procedure
The first and most critical step is to properly prepare the case and the headphones themselves. Make sure there is enough charge in the charging case, as the reset process requires energy to write new parameters into the controller's memory. Put both earphones in the case and wait for the charging indicators to light up.
The next step is to clean the contacts, and on each earphone and inside the case are metal contacts that are often oxidized or contaminated by earwax, and take a dry cotton swab or soft tissue and gently wipe those areas, and poor contact can cause one of the earbuds to fail to wake up during the reset.
β οΈ Warning: Do not use wet wipes or alcohol immediately before the procedure unless you are sure of drying out completely.
It is also important to understand that before you start manipulating, you need to remove the device from the Bluetooth list on your smartphone. If you do not, the phone may automatically try to reconnect during the reset process, which will disrupt the settings.
- π Check the charge level of the case and the headphones themselves - it should be at least 30%.
- π§Ό Carefully wipe the charging contacts on the headphones and inside the case with a dry cloth.
- π± Remove the profile of My True Wireless EBs Basic A2DP" from Bluetooth settings on your phone.
- π« Close all applications that use microphone or audio (dictophone, Skype, games).

The classic method of resetting through the case button
The most common method that works for most firmware versions involves using a physical button on the charging case.This method is standard for the Xiaomi ecosystem and requires precise timing.
Once the headphones are in the case, find a round button on the front or back (depending on the revision of the case). You need to press and hold this button. The indicators on the headphones will flash, signaling the beginning of the process of flashing the internal modules.
The key here is the duration of the press. You need to hold the button about 20-30 At some point, the lights will blink red several times and then light up white, and that's a signal that the reset has been successful.
π‘
If the indicators donβt flash red, try moving the headphones slightly in the case to improve contact with the charging pinoles, and try again.
It's important to keep the button on the go, even if it doesn't seem like anything's happening, and the system can delay the response for a few seconds to prevent accidental resets, and patience in the process is key to success.
Alternative method without a button (touch reset)
In some rare cases or on specific hardware versions, the button on the case may be missing or malfunctioning, and touch reset comes to the rescue, requiring greater coordination of movements, as you need to simultaneously act on the touch areas of both headphones.
Remove both earbuds from the case. Wait for them to turn on (usually the indicators flash white).Now you need to press the touch areas of both earbuds at the same time and hold your finger for about 5-7 seconds until they turn off (the indicators go out or light up red).
Without letting your fingers go, wait a few more seconds until the headphones turn on again. Then press the sensors again for 20 seconds. This method is less reliable than the button on the case, but can save the situation if the physical button is broken.
- π Remove the headphones and wait for them to turn on.
- β Press the touch panels of both headphones simultaneously on 5-7 seconds before.
- β³ Without letting go, wait for re-energization and hold for another 20 seconds.
- π Watch the indicators: triple flashing red means success.
Why doesn't the sensory method work?
Table of indicators and their values
Understanding the Xiaomi Airdots 2 color indication is critical for diagnosis. Different blinking modes tell the user about the current status of the device. Below is a table that will help you interpret LED signals during and after the reset procedure.
| Color of indicator | Blinking mode | Meaning |
|---|---|---|
| White | Slow blinking | Interconnection mode (device search) |
| White | It's burning all the time. | The device is connected to the smartphone |
| Red. | It's burning all the time. | Charging is in progress. |
| Red. | Fast blinking (3 times) | Successful reset or critical error |
| Absent. | - | Headphone off or discharged |
Note that if the indicator continues to flash red and white quickly after reset, this may indicate a desynchronization of the left and right channel, in which case the procedure may need to be repeated, paying special attention to the simultaneity of button pressing.
Proper pairing after discharge
After successfully completing the Hard Reset command, the headphones go into pairing mode, now you need to reconnect them correctly to the phone, turn on Bluetooth on your smartphone and start looking for new devices.
The list of available devices should be called "Mi True Wireless EBs Basic A2DP." Click on it to connect. Importantly, you only need to connect to one name, even if there were two before, and after reset, they should work as a single stereo system.
β οΈ Note: If you see two identical devices on the Bluetooth list, don't connect to either. Repeat the reset procedure because the headphones didn't sync with each other.
Sometimes the phone may remember the old profile and try to use it. To avoid conflicts, make sure that there are no old entries with the same name left in the Bluetooth settings before connecting a new device. Clearing the Bluetooth cache on Android can also speed up the process.
π‘
The main sign of success is the appearance of only ONE device in the Bluetooth list instead of two separate channels.
Addressing common problems
Even with strict adherence to instructions, nuances can occur, such as one earbud can work and the other can be silent, a classic sign of TWS (True Wireless Stereo) desynchronization, in which case resetting often helps restore the connection between the master and the slave headphones.
Another problem is the quiet sound or lack of bass after reset, which may be due to the codec being reset to a standard SBC. Check with developer options (for Android) or in the audio settings which codec is selected, and try switching to AAC if the device supports.
If the case doesn't charge the headphones after the reset, check if the buttons or sensors are stuck. Sometimes the software reset doesn't help if the problem is physical, such as the oxidation of the board inside the case, in which cases hardware diagnostics may be necessary.
- π The sound is only in one headphone: put both in the case, close the lid, open and repeat the reset.
- π Low Volume: Check the absolute volume settings in Android Developer Mode.
- π Case not charging: brush contacts with a toothbrush (dry) or alcohol (with caution).
- π± Phone doesn't see headphones: reboot your smartphone and make sure the Bluetooth module is active.
