The situation when your favorite wireless headphones suddenly refuse to connect to your smartphone is familiar to many users of the Xiaomi ecosystem. Instead of the usual notification sound and automatic connection, you see an endless search for devices or an error message. This can occur for various reasons, from the banal discharge of the battery to software conflicts in the Android or iOS operating system.
Before you panic and carry your device to the service center, you need to do a number of diagnostic actions. Often the problem lies in the failure of the Bluetooth protocol, overflowing pairing memory or the need to force resetting. In this article, we will discuss the algorithms for the AirDots, Redmi Buds and Mi True Wireless models, which will help restore the functionality of the gadget.
It is important to understand that wireless headphones are complex electronic devices that depend on the stability of the radio channel. Interference from Wi-Fi routers, microwave ovens or other Bluetooth gadgets can temporarily disrupt communication, but if the problem is persistent, a systematic approach to fix it is required.
Basic diagnostics and charge check
The first step should always be to check for basic things that are often overlooked, make sure that both headphones and the charge case have sufficient energy levels, and if the indicators do not light up when extracted from the case, the contacts may have oxidized or the built-in battery has completely died.
Try to wipe the metal contacts on the headphones themselves and inside the case with dry soft cloth. Sometimes a layer of fat or dust blocks charging, which causes the device to not turn on and therefore does not go into pairing mode. After cleaning, leave the headphones in the case for 15-20 minutes.
⚠️ Warning: Do not use wet wipes or alcohol to clean contacts unless recommended by the manufacturer, as liquid can get inside the case and damage electronics.
Also worth checking is that the connection is locked at the smartphone system level. Make sure the Bluetooth module is activated and visible to other devices. Try to find headphones from another phone or tablet to localize the problem: whether it is in the headphones or in the main device.
Resetting of Xiaomi headphones (Hard Reset)
The most effective method of solving software errors is to completely reset the settings to factory settings, which clears the internal memory of the headphones from old pairing profiles that may have conflicted with the new connection.
For most models, such as the Redmi AirDots or Mi True Wireless Earbuds Basic, you need to place both headphones in the charging case. Then, without closing the lid, find the function button on the case case case (if any) and press it for 10-15 seconds before changing the color of the indicator. If the button on the case is not, the procedure is performed through the touch panels of the headphones themselves.
☑️ Reset algorithm without a button on the case
In models without a button on the case, you often need to touch the touch areas of both headphones simultaneously and hold them for about 20 seconds. The indicators should light up red several times, which signals a successful reset. After that, the headphones should be placed again in the case, close it and open after 10 seconds to re-activate the mode.
Once you reset, be sure to remove the old device from the Bluetooth list on your phone. Find the name of your Xiaomi Earbuds in the list of previously connected devices and click "Forget" or "Disable." Only then you can start the search again.
Profile removal and re-pairing
Often the reason for the inability to connect is the "stick" of the old connection profile. The smartphone tries to connect using stored encryption keys, which are no longer relevant for headphones after reset.
Go to your smartphone's Bluetooth settings. Find your headphones (e.g. Mi True Wireless EB Basic) in your device list. Click on the gear icon or device information and select the option to "Unpair" or "Delete device" and repeat this action if there are multiple entries on the list with the same name.
Now put the headphones in visibility mode. Usually when you open the case lid, they automatically start searching if you've reset them before. If you don't have automatic search, press the touchpads or the button on the case so that the indicators start flashing white quickly, which means Pairing Mode.
💡
If the phone finds the headphones but says “I couldn’t connect,” try temporarily switching the phone to flight mode for 5 seconds, and then turning on Bluetooth again.
The table below contains the model names and indicators of their condition, which will help you understand what mode the device is in:
| Model | Interconnection indicator | Error indicator | Resetting action |
|---|---|---|---|
| Redmi AirDots | Fast flashing white | Red (5 times) | Hold the sensors down for 20 seconds. |
| Mi True Wireless 2 | Blinking white | Absent. | Case button 10 seconds. |
| Xiaomi Buds 3 | Pulsation white | Orange | Case button 10 seconds. |
| Redmi Buds 3 Pro | Blinking white | Red. | Case button 10 seconds. |
Problems with the Xiaomi Earbuds app
Many Xiaomi headphones require a proprietary app to be customized for advanced customization, but sometimes it is the source of problems if it has an outdated version or conflicts with system resolutions.
In some cases, updating the firmware of the headphones through the application can get stuck in the boot phase. If this happens, do not immediately try to reboot the phone. Check the stability of the Internet connection and the availability of free space in the memory of the smartphone. Sometimes it helps to clear the cache of the Xiaomi Earbuds application itself through the Android settings.
⚠️ Note: During the update of the firmware headphones do not open the case cover and do not move the smartphone from the case by more than 1 meter, otherwise the process will interrupt, and the device may stop working correctly.
If the app crashes when you try to connect, try removing it, restarting your smartphone and installing it again from the official Google Play or App Store, and checking if the phone has a modified firmware that can block Bluetooth system services.
Hidden functions of the application
Bluetooth Conflicts and System Settings
Sometimes the problem is not the headphones, but the overcrowded list of paired devices on the smartphone itself. 10-15 Devices, new connections can be initiated with errors or delays. Make room by removing old, unused gadgets.
You should also look at the codec versions. If you're trying to connect your aptX Adaptive or LDAC headphones to your old smartphone, you might have coding conflicts. Try changing your Android developer's Bluetooth priority codec to SBC or AAC.
In rare cases, a complete reset of a smartphone’s network settings helps.This action will delete all stored Wi-Fi passwords and Bluetooth pairings, but often resolves deep network system errors. The path to the feature usually looks like this: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
💡
Resetting your smartphone’s network settings is a radical, but often the only way to resolve a Bluetooth protocol conflict without flashing your phone.
Hardware malfunctions and diagnostics
If the software didn't work, there might be a hardware breakdown, check if the sensors on the headphones are reacting, and if one earphone doesn't show signs of life even after a long charge and cleaning of the contacts, its battery or power controller may have failed.
Notice the behavior of the indicators. If the indicator lights up red when placed in a case, but goes out after a couple of seconds, this can indicate battery bloating or critical wear, in which case further operation can be dangerous.
If the case is not charging itself or charging the headphones, the problem may be a Type-C connector or an internal case board. Try using a different cable and power supply, as some cases are sensitive to current.
Specificity of connecting to iOS and other OS
iPhone owners may have difficulty connecting due to Apple's stricter security protocols.Make sure the device has the latest version of iOS installed.Occasionally, disabling Find iPhone during initial pairing helps, although it reduces security.
On devices with the HarmonyOS operating system or pure Android from other vendors (Samsung, Realme), the process may be characterized by the absence of quick-configuration pop-ups, in which case the connection is made exclusively through the standard Bluetooth menu without the use of proprietary animations.
If none of the methods worked, and the headphones can't see any device within a 5-meter radius, the Bluetooth module inside the headphones is likely to malfunction, requiring an authorized service center to diagnose and replace components.
