When Xiaomi wireless headphones stop working in pairs, it's one of the most common problems for users of the ecosystem. Often you take out a case, put on a headset, and the sound is only in one ear, or one of the devices simply does not turn on and does not respond to touch. This is annoying, since the full stereo disappears and the mono mode does not allow you to enjoy music or movies in the proper quality. However, in most cases this does not mean a breakdown, but only indicates a software failure or dissynchronization between the right and left modules.
The causes of this malfunction can be very different: from the banal discharge of one of the elements to the complex conflict of Bluetooth protocols. Desynchronization often occurs if the headphones were removed from the case at different times or if they previously connected to other smartphones. Also, the work is affected by contamination of contacts, which causes one of the modules to not charge and goes into deep sleep. Understanding the nature of the problem is the first step to its successful solution without going to the service center.
In this article, we will go into detail the algorithms that will help restore normal operation of your headset. We will look at methods of forced reset, cleaning the pairing list and the correct sequence of on. The critical point is the simultaneous removal of both headphones from the charge case during the initial setup. If you follow the instructions clearly, the probability of a successful recovery will be more than 90%, which will save you time and money.
The main reasons for the desynchronization of headphones Xiaomi
Before proceeding with active repair actions, it is necessary to understand why the failure occurred. TWS-In the case of the headset, it suggests that one ear is a master device that transmits a signal to the other, and if communication between the two is disrupted, the second module stops receiving audio streams. This can happen after the update of the operating system of the smartphone, when the old connection profiles cease to be properly processed by the new software.
Another common cause is different battery levels. If one earbud wasn't fully inserted in the case, it might have gone to zero while the other was charging, and in this state, the power controller locks the device to protect the battery, and it doesn't go out of storage. It's also worth considering the impact of third-party devices: if your AirDots or Redmi Buds had previously connected to a friend's laptop or tablet, they could automatically dock with it when turned on, ignoring your phone.
⚠️ Attention: If one of the headphones is silently intermittent or flashes the indicator differently from the other, the problem may be oxidation of the charging contacts inside the case.
Physical interference can also be jammed by powerful nearby sources or metal structures. However, if the problem is persistent and in different places, it is the logical connection of devices. The frequency interference of Wi-Fi routers can also affect the stability of the connection, especially in the 2.4 GHz range that most budget headphone models use.
Preparing for setting up and cleaning the pairing list
The most important step that users often ignore is cleaning up your connection history completely. While your smartphone remembers an old, possibly damaged configuration, the new setup may not be successful. You need to go to your mobile device's Bluetooth settings, find the name of your headset (for example, Mi True Wireless Earbuds Basic) in your list of devices, and select the "Forget Device" or "Delete" option.
Once removed, you need to turn off Bluetooth completely on your smartphone, which will break all background search processes. If you have the option, you better also restart the phone itself to reset the Bluetooth module cache. Now your headphones are in "invisibility" for the phone, which is the perfect condition for starting a clean setup.
Make sure both headphones are sufficiently charged.Put them in a case and plug it into the charger for 15-20 minutes, even if the indicators show full charge.This is necessary to align the voltage on the battery banks, which often helps synchronize their operation.
- 🔋 Make sure the case is at least 50% charged for stable operation.
- 📱 Remove the device from the Bluetooth list on all gadgets they’ve connected to before.
- 🔄 Reboot your smartphone to reset the Bluetooth stack.
- 🧹 Wipe metal contacts on headphones and inside the case.
☑️ Preparation for reconnection
Algorithm of full reset (Hard Reset) headphones
If a simple cleaning of the pairing list didn't help, you need to perform Hard Reset.This process returns the headphones to factory settings, erasing all temporary files and resetting the master device.The reset technique may vary slightly depending on the model, but the general principle remains the same for most Xiaomi and Redmi products.
Place both earbuds in the charge case. Make sure they are securely secured with magnets and the charge indicators are on. If there is a physical reset button on the case (usually a small hole or button on the end), press and hold it for 10-15 seconds until the indicator flashes white or red. If the button is not, touch control is used.
For models without a physical button, while the headphones are in the case, press and hold the touch zones on both headphones simultaneously. Hold for about 20-30 seconds. The indicators should blink several times, then go out and light up again, signaling the completion of the reset. After that, remove them from the case - they should start blinking quickly, entering the pairing mode.
What if the reset doesn’t work the first time?
It's important to take your time. If you take your headphones out too early, the reset process will stop. The reset cycle must complete, as usually indicated by a change in color of the LEDs or a beep, and after a successful reset, the headphones will look for each other again, creating a new internal network.
Proper pairing with Android and iOS devices
Once you do the reset, the key is the primary pairing. Take both of the headphones out of the case at the same time. Don't hold one in your hand and the other in the case. They have to lie next to each other for 3-5 seconds to find each other and sync. Only after one of the indicators (usually the right one) flashes slowly, and the other goes out or flashes less often can you open Bluetooth on the phone.
Turn on Bluetooth on your smartphone and start looking for new devices. Your model name should appear on the list. Click on it to connect. If the system requests a pairing confirmation, agree. In some cases, you may need to enter a pin code, the standard value is 0000 or 1234, although modern Xiaomi models do not.
If the headphones are not there, try to approach the phone or, conversely, step away 2-3 meters to prevent overloading of the signal. Make sure that other Bluetooth devices within a radius of 5 meters are turned off so that they do not intercept the search signal.
| Model headphones | Indication of discharge | Retention time | Feature |
|---|---|---|---|
| Mi AirDots / Redmi Airdots | 5 times flashes red | 20-25 seconds | Sensory management |
| Mi True Wireless Earbuds | White flashing | 10-15 sec. | The button on the case |
| Xiaomi FlipBuds | Orange indicator | Holding the button | Automatic entry into mode |
| Redmi Buds 3/4 | Fast blinking. | 10 seconds (button) | Support for Fast Pair |
Use of Mi Wear and Xiaomi Earbuds
For deeper customization and diagnosis, it is recommended to use official applications from the manufacturer. Mi Wear (formerly Mi True Wireless) is suitable for global versions of devices, and Xiaomi Earbuds is suitable for Chinese versions or some models. These utilities allow not only to connect headphones, but also to update their firmware, which often solves software bugs.
Install an app from Google Play or the App Store. Run a device scan. If the headphones are in pairing mode, the app will detect them and suggest that they be connected. Inside the app, you can see the charge of each headphone individually, which helps to identify imbalances, and it also has the ability to search for headphones and adjust the touch controls.
The firmware update is a powerful bug fixing tool. If a manufacturer has released a new firmware, be sure to install it. The process takes a few minutes, and at that time the headphones should be near the phone, and the smartphone screen should not go out. After the update, the structure of Bluetooth packets can change, which will eliminate compatibility conflicts.
💡
The Mi Wear app may not see the headphones if the phone is power-saving. Turn it off while you set up and update.
You can also program-reset the app if the physical buttons don't respond. Find the Settings or About section and select Reset or Unlink, which will force you to break the link and prepare the gadget for a new one.
Diagnostics of hardware faults and contacts
If the software methods didn't work, you should look at the physical condition of the devices. Look at the charging connectors on the headphones themselves. There may be earwax, dust or pile from the clothes. This plaque isolates the contacts, and the earphone, lying in the case, does not charge, thinking that it is turned off.
Use a dry toothbrush or cotton swab lightly soaked in alcohol (not in water!) to gently clear the contact areas. Let the alcohol evaporate completely before putting the headphones in the case. Also check the charging pins inside the case itself - they may be pressed or contaminated.
⚠️ Warning: Never use sharp metal objects (needles, scissors) to clean contacts inside the case.You may damage the insulation or close contacts, which will short-circuit and the case will fail.
Another test is to test each headphone individually, plug the left one in, listen to the sound, then the right one, and if one of them wheezes, cracks, or doesn't play bass, even in mono mode, the problem could be the speaker or the membrane, and then the software reset won't help, and you'll need to change the speaker or the entire module.
Frequent questions and problems when connecting
Users often experience a situation where the headphones seem to be connected, but the sound only goes to one channel (left or right), even if both are playing. This is a sign that there has not been a stereo pairing. In the Bluetooth settings of the phone, sometimes (rarely) there is an option "Mono-audio". Check in the "Special features" -> "Hearing" section to turn this option off.
It also happens that one earphone discharges faster than the other. This is normal for a master device that broadcasts a signal. However, the difference should not be critical (for example, 10% versus 90%). If the difference is large, try using only one earphone for several charge cycles to level the battery life, or leave them in a case on overnight charging.
💡
If none of the software methods helped and cleaning contacts did not give results, the probability of failure of the battery of one of the modules is high.
In some cases, flashing a Bluetooth phone helps, but it's a tricky procedure. It's easier to try connecting your headphones to another device (a different phone or tablet), if they work in pairs perfectly, then the problem is that your main smartphone and a particular version of Android/iOS are compatible.
