Xiaomi’s wireless headphones suddenly lose connection to a smartphone, a familiar experience for many ecosystem users, and can occur at the most inopportune moment: during an important call, in the midst of a gaming session, or at the peak of a favorite music track. Instability of Bluetooth connection does not always indicate a fatal device breakdown, often the problem lies in software conflicts or banal interference.
The first thing to do is to assess the scale of the problem: the sound is lost on only one ear or the disconnection occurs entirely on both channels, and the distance to the phone and the presence of physical barriers. The critical factor is often the battery level below 15% when the system forcibly reduces the transmitter power to save energy. In most cases, the situation can be corrected by software methods without resorting to the services of a service center.
Next, we’ll look at a detailed algorithm that will help restore the stable operation of your Mi True Wireless Earbuds or wired models with a Bluetooth adapter. You’ll learn how to correctly reset settings, update firmware through the Mi Wear or Xiaomi Earbuds app, and how to eliminate the influence of third-party factors on signal quality.
The main reasons for the break of Bluetooth connection
Understanding the nature of the malfunction is half the success of fixing it. Most often, users experience software failures in the operating system of Android or iOS smartphones that improperly process requests for peripheral connection. A crowded Bluetooth cache can cause addressing conflicts, causing the phone to "forget" the device or cannot maintain a stable communication channel.
Physical obstacles also play a huge role. The 2.4GHz signal that most headphones use doesn't get through walls, metal structures, even the human body. If you put your smartphone in the back pocket of your jeans, and you're in a crowded place with lots of Wi-Fi routers, the odds of out-synchronization increase many times over.
The firmware version of the headphones deserves special attention. Manufacturers regularly release updates that fix connection stability errors. If your AirDots or FlipBuds are running an older version of the software, they may not be compatible with the new security patches of the smartphone.
- 📶 Radio interference: Microwave ovens, routers and other Bluetooth gadgets working nearby create a "porridge" on the air.
- 🔋 Low charge: With a discharged battery, the communication module is unstable and can spontaneously shut down.
- 📱 Version conflict: Incompatibility of Bluetooth protocols (e.g. 5.0 and 4.2) when trying to connect old and new devices.
- 🧹 Contact contamination: Oxidation or dirt on charging contacts in the case prevents the headphones from charging to 100%, leading to a quick discharge.
⚠️ Note: If the headphones are only turned off when running apps (such as TikTok or Instagram), the problem may lie in the permissions to use the microphone or the energy saving of the application itself, rather than in the headset.
Basic Reboot and Reconnect Devices
The simplest and most often ignored method is the full cycle of rebooting the pair of "smartphone-earphones." You should not limit yourself to just turning off Bluetooth in the notification curtain, since the communication module may not reset its temporary errors. 10-15 seconds and turn it on again.
For headphones, the reset procedure is to put them in a charging case and close the lid for 10 seconds, and then you take them out and try to reconnect, and if that doesn't work, you'll need a deeper intervention, which is to remove the device from the paired list.
Go to your phone's Bluetooth settings, find your Xiaomi Earphones in the list, and select "Forget Device" or "Unpair" option, which will clear the encryption keys and saved profiles.
☑️ Checklist for reconnection
It is important to monitor the indicators on the case and the headphones themselves during the time. A flashing white or red light usually signals a pairing mode. If the indicators behave strangely (for example, flashing red constantly), this may indicate a deep discharge or a malfunction of the battery.
Full reset of headphone settings (Hard Reset)
If a conventional reconnection fails, you need to reset the headphones to factory settings, which returns the headset’s internal memory to its original state by removing all accumulated errors and profile conflicts. The reset method may vary depending on the model: Mi True Wireless Earbuds Basic 2, Air 2 Pro or Redmi Buds.
For most models without touch controls (such as the old AirDots), the procedure is this: remove the headphones from the case, make sure they are not connected to the phone. Then press and hold the touch zones on both headphones simultaneously for 20 seconds. The indicators should flash red several times, after which the headphones will turn off.
For models with a charging case that has a button (e.g. Mi True Wireless Earphones 2), the algorithm is different: Place both headphones in the case, leave the lid open. Press and hold the function button on the case for 10-15 seconds until the indicator on the case flashes white.
| Model headphones | Resetting method | Indication of success |
|---|---|---|
| AirDots / Redmi Buds 3 Lite | Hold the touch zones for 20 seconds. | Triple flashing red |
| Mi True Wireless 2 / 2S | Case button 10 seconds. | White flashing of indicator |
| FlipBuds Pro | Case button 10 seconds. | Orange blinking |
| Noise Cancelling Earbuds | Touch zones 5-10 seconds | Sound signal and switch off |
After resetting, the headphones will automatically go into pairing mode. You will need to find them again in the phone's Bluetooth menu. Note that after reset, the equalizer settings may be lost if they were stored in the headphone memory rather than in the application.
What if the reset didn't help?
Update the firmware through the Mi Wear app
Modern Xiaomi headphones are complex gadgets with their own operating system. Code bugs can lead to memory leaks and connection breaks. Mi Wear (for global versions) or Xiaomi Earbuds (for Chinese versions) are used to manage and update.
Install an app from Google Play or the App Store. Connect your headphones to your smartphone and open the program. If the update is available, you'll see a notification on the home screen. The update process is critical: it fixes known Bluetooth protocol bugs and improves noise reduction algorithms, which can also affect communication stability.
Keep your headphones close to your phone (no more than 10-15 cm) and do not open the case cover during the upgrade. Interrupting the process can "brick" the device, after which it will be extremely difficult to restore it. Make sure that the charge of the case and the headphones themselves is at least 50% before the procedure.
- 🔄 Automatic search: The app checks Xiaomi servers on its own every time you connect.
- 📲 Internet Stability: A stable Wi-Fi or service pack is required to download 4G linkage.
- 🔋 Power saving: Turn off the power saving mode on your phone so it doesn’t interrupt data transfer.
⚠️ Warning: Do not try to update the firmware if the phone battery is less than 30% dead.Suddenly turning off the smartphone while writing data to the memory of headphones can lead to irreversible consequences.
💡
Tip: If the app doesn’t see the headphones or doesn’t show an update, try clearing the cache of the Mi Wear app itself in Android settings (Settings → Apps → Mi Wear → Memory → Clear the cache).
Power saving settings and Android
One of the hidden causes of connection problems are aggressive power saving settings in the MIUI or HyperOS shell.The system can force the Bluetooth module to turn off or restrict the background operation of the application that controls the headphones, considering them inactive.
To rule this out, go to your phone's settings, look for Battery or Advanced Settings, see if Ultra-Energy Saving is enabled, and go to the settings of a particular Mi Wear or Bluetooth app and allow it to "Start" and run in the background without restrictions.
For advanced users, the Developer Options section is available. You can find settings that affect Bluetooth. For example, the Bluetooth Audio Codec option allows you to select a codec (SBC, AAC, aptX). Try switching the codec to a more basic one, such as an SBC, to see if the gap problem disappears. Sometimes complex codecs are unstable in a noisy air.
There is also a Bluetooth Wait Time option on the developer menu, which means make sure it is not set to Never or too short, although standard settings are usually optimal.
Hardware malfunctions and physical impact
If software is exhausted, you might want to consider the possibility of physical failure, because inside the headphones and the case, there are miniature antennas, and if you drop the device, get moisture, or even hit it hard, you can detach the antenna module from the board, and you can visually see that, you need to disassemble it.
Another common problem is contact oxidation. If you used headphones in the gym, sweat could get inside the case or onto charging contacts. This creates resistance, the headphones don't charge to the end and discharge quickly, which is perceived as a communication break. Wipe the contacts with a dry soft cloth or cotton swab slightly moistened in alcohol (carefully!).
Check battery integrity. Lithium polymer batteries degrade over time. If the headphones are 2-3 years old, they can hold a charge for 15-20 minutes, after which the voltage drops below the critical threshold of the Bluetooth module, and communication is cut off.
💡
If the headphones are turned off on only one ear or when moving the head, the most likely problem is the antenna or the plume rupture inside the body, which requires repair.
