Have you pulled Xiaomiβs new wireless headphones out of the box (or your proven Redmi AirDots suddenly stopped connecting), but your smartphone stubbornly βcanβt seeβ them? Or the connection breaks after a few seconds? This problem is familiar to many owners of the brandβs gadgets β from the budget Mi True Wireless Earphones 2 to the flagship Xiaomi FlipBuds Pro. The reasons can lie in software failures and hardware malfunctions.
In this article, we will analyze all possible scenarios, from basic checks (battery charge, enabled Bluetooth) to deep settings (reset to factory settings, flashing). MIUI, For example, did you know that some headphones have a forced pairing mode that is activated by holding the button to 10?+ Or that Xiaomi is blocking the connection to devices with an outdated version of Bluetooth?
Don't rush your headphones to the service center, because you can solve the problem yourself in about 90 percent of the time in 5 to 15 minutes, and let's start with the simplest and gradually move on to the most complex methods.
1.Basic checks: 5 steps before a deep diagnosis
Before digging into your phone's settings or disassembling your headphones, make sure the problem isn't on the surface.These actions take less than a minute, but often save hours to find a solution.
- π Headphone charge level: even if the indicator is on, the battery could be discharged to a critical level (below 5%). Connect the case to charge for 10-15 minutes and try to pair again. In AirDots 3 Pro and later, at a discharge below 3%, the headphones automatically turn off the Bluetooth module.
- π± Bluetooth on your phone: check that the module is enabled not only in the notification curtain, but also in the settings (Settings) β Connections β Bluetooth. On some firmware MIUI After the update, the permissions for Bluetooth are reset.
- π Reboot devices: Turn off and turn on the headphones (remove from the case and hold the button for 5 seconds), then restart the smartphone.
- π¦ Device compatibility: Xiaomi headphones with Qualcomm chip QCC3040 (FlipBuds Pro will not work properly with Bluetooth 4.0 phones (released before 2016.
- π§ Connecting to another device: try pairing your headphones with another phone, tablet, or laptop. If they connect, it's a problem in your smartphone, if not in the headphones themselves.
β οΈ Note: In headphones Xiaomi Mi True Wireless Earphones 2 Basic and Redmi AirDots 2 after the battery is completely discharged, the pairing settings are reset. To restore the connection, you will have to perform a forced reset (about this in section 3).
2. Bluetooth problems on the smartphone: settings MIUI
If the headphones are not defined by any device, the problem is likely in themselves, but if other gadgets (columns, fitness bracelets) connect normally and Xiaomi does not, the smartphone is to blame. MIUI There are several βpitfallsβ that are not written in official manuals.
The first thing to do is clear the Bluetooth cache and reset the network settings:
- Go to Settings β Applications β Application Management.
- Click on the three dots in the upper right corner and select Show System Processes.
- Find Bluetooth in the list, open it and click Clear Cache and Reset Settings.
- Reboot the phone.

If your smartphone is on MIUI 12.5+ And Xiaomi headphones are connected, but the sound is interrupted -- disable the dual Bluetooth function in the developer settings. AAC, which is used by most of the brand's headphone models.
3.Reset Xiaomi headphones to factory settings
If the basic methods don't work, the next step is to hard-reset the headphones, which removes all the connections that you've saved and returns the device to a boxy state, and the way you reset it depends on the model.
| Model headphones | Resetting method | Notes |
|---|---|---|
| Redmi AirDots (1β3), Mi True Wireless Earphones 2 | Place both headphones in the case, then hold the button on the case for 15-20 seconds until the indicator starts flashing red and white. | After resetting, the headphones will automatically go into pairing mode. |
| Xiaomi FlipBuds Pro, Buddy Buds | Hold the touchpad on both headphones at the same time for 10 seconds until you hear the beep. | The firmware is not lower than 1.4.0.3. |
| Mi Air 2 SE, Air 2 Pro | Remove the headphones from the case, then hold the button on the case for 10 seconds (the indicator flashes orange). | After resetting, the case may require recharging. |
| Xiaomi Air 3 Pro | Place the headphones in the case, then press the button on the case 5 times in a row at an interval of 1 second. | Mi Earphones application is required to confirm the reset. |

Updating the firmware is the only way to fix hardware pairing errors caused by Bluetooth stack incompatibility. For example, Redmi AirDots 2 headphones before version 1.2.0.7 had a bug that prevented them from connecting to phones with a Snapdragon 865 chip (such as Xiaomi Mi 10).
5. Hardware malfunctions: when without repairs can not do
If none of the software methods worked, the problem could be a physical breakdown of the headphones or smartphone, and here are the most common hardware reasons:
- π Damaged contacts in the case: over time, the spring contacts become oxidized or deformed, which prevents the headphones from charging or turning on.
- π‘ Faulty Bluetooth module: If other devices are not connected to the phone, the problem is the antenna or Bluetooth chip.
- π Bloated battery in headphones: if the headphones suddenly stopped holding the charge and turned off after a few minutes, the battery could fail.
- ποΈ Damaged Control Board: If the headphones don't respond to button presses and don't turn on, it's likely that the controller has burned.
How to diagnose a hardware malfunction:
- Check the case, plug it into the charger, see if the indicator is on, and if it's not, there's a problem with the battery or the case board.
- Call the contacts: with the multimeter, check the resistance between the charging contacts on the headphones and the case. Normally, it should be 0.5-1.5 Ohms.
- Test on another device: try connecting your headphones to a friend's phone or tablet, and if they're not detected anywhere, the problem is with them.
β οΈ Attention: Xiaomi headphones often fail the Bluetooth antenna, which is located in the earphone loop. If you notice that the connection disappears when you turn the head, most likely, the antenna is damaged. In this case, repair is possible only in the service center (replacing the loop will cost 1500-2500). β½).

- π‘ Repair of Bluetooth module: 1500-2500 β½.
- π Replacement of contacts in the case: 500-900 β½.
What if the headphones are connected, but the sound is only in one?
6. Alternative methods of connection (if nothing helps)
If standard methods do not work, you can try non-obvious solutions that sometimes save in desperate situations.
Method 1: Connecting through a third party application
Some applications (such as Bluetooth Auto Connect or Btool) allow you to force a connection to a device even if it does not appear in the standard Bluetooth menu.
- Install Bluetooth Auto Connect from Google Play.
- Open the app and click Search devices.
- In the list, find your headphones (they can be displayed under a technical name, for example, BES2300YM For Redmi AirDots 3).
- Press Connect and confirm the pairing.
Method 2: Change Bluetooth Regional Settings
In some firmware MIUI There are restrictions on connecting devices from other regions:
- Activate Developer Mode (as described in Section 2).
- Go to Settings. β Additionally. β For developers β Bluetooth Region.
- Set the value of United States or Europe (depending on the headphone model).
- Restart your phone and try to connect again.
Method 3: Use ADB-Teams (for advanced users)
If the headphones are defined but not connected, you can manually clean their recording in the system through ADB:
adb shell settings delete global bluetooth_device_address
adb shell settings delete global bluetooth_device_nameAfter completing the commands, restart the phone and try to connect again.
π‘
Apps like Bluetooth Auto Connect often help connect headphones that arenβt visible on the standard menu, which is because they use low-level Bluetooth protocols to bypass the restrictions. MIUI.
7. Prevention of connection problems
To avoid problems with pairing in the future, follow these recommendations:
- π Don't discharge your headphones to zero: try to recharge them when the charge drops below 20%.Full discharge can damage the Bluetooth controller.
- πΏ Avoid moisture: even if the headphones have protection IPX4, ingress of water into case contacts often leads to corrosion.
- π± Update your firmware: Check for updates in the Mi Earphones app every 1-2 months.
- π Reset the settings: if the headphones began to glitch (self-disconnect, distort the sound), reset once every six months.
- π¦ Store in a case: do not leave headphones outdoors - this leads to oxidation of contacts.
If you often connect headphones to different devices (for example, to your phone and laptop), use multi-point connection (if the model supports).
- Connect the headphones to the first device.
- Open Mi Earphones and activate the option of dual connection.
- Connect the headphones to the second device via Bluetooth.
Note: In multi-point connection mode, the sound quality may deteriorate due to switching between devices.
