Sometimes owners of the popular Xiaomi Mi True Wireless Earbuds face a situation where the headset stops working as a single unit. Instead of stereo, only one headphone plays, or the devices do not see each other at all when trying to connect to a smartphone. This is a classic synchronization failure that can occur after a battery drain, a Bluetooth protocol update in the phone, or a software failure in the headset itself.
Reconnecting left-right modules is a procedure that can be done on its own without going to a service center. Synchronization allows devices to re-recognize each other and merge into a single audio system. Below, we will discuss in detail the algorithm for actions for various models, including Mi True Wireless Earbuds Basic, AirDots and newer versions.
Before you start complex manipulations, it is worth checking the obvious things: make sure that the charging case and the headphones themselves have a sufficient level of charge. Often the problem lies in oxidized contacts or a discharged battery of one of the modules, which prevents the normal start of the mating process.
Reasons for the desynchronization of wireless headphones
Understanding the nature of the problem helps to avoid recurrence in the future. The main factor that causes communication to be lost between modules is the desynchronization of Bluetooth profiles. When you connect the headset to a new phone, the old settings can conflict with the new ones, causing a connection error.
Another common reason is that one of the headphones is completely discharged, and if the left module is dead and the right one is still working, they may not be able to sync with each other when they are put in the case, and as a result, when they are removed, they do not recognize the partner and start working independently.
⚠️ Attention: Frequent connection of the headset to different devices without first breaking the connection can lead to the accumulation of errors in the memory of the Bluetooth module.
Also worth mentioning are firmware failures: In rare cases, Xiaomi Mi True Wireless Earbuds can freeze in standby mode. To fix the situation, a complete reset is often required, which will force the internal algorithms to restart.
Preparation for mating
Before you start any action, you need to get the equipment properly prepared, which is a critical step in the success of the whole operation. First, put both earbuds in the charge case and close the lid. Leave them there for 10-15 minutes to make sure they start charging.
Next, take your smartphone and open your Bluetooth settings. Find your model (e.g. Mi True Wireless Earbuds Basic) in the list of previously paired devices and select the option “Forget device” or “Delete” to clear the cache of old connections.
Now turn off Bluetooth on your phone completely. This is to ensure that the headset does not try to automatically connect during the setup process. Make sure the contacts on the headphones and inside the case are clean. If necessary, wipe them with dry soft cloth, removing dust and pile.
Basic synchronization method for Basic and AirDots models
The most common way to restore the Basic and AirDots headsets is to get both headphones out of the case at the same time, and they have to flash a white light, which means a pairing waiting mode.
It's important to wait until one of the lights goes out and the other keeps flashing, which means that the left and right channels found each other and merged, so you can turn on Bluetooth on your smartphone and search for the device on the list of available channels.
What to do if the indicators flash differently?
If the colors of the indicators are different or the flashing is chaotic, then the headphones are not synchronized with each other. In this case, you need to perform the reset procedure (Hard Reset), described in the next section.> If the automatic connection does not occur, try the following sequence: tap the touchpad on both headphones 5 times quickly. This action often forcibly initiates a search for a partner. After that, put them again in the case, close the lid for 5 seconds and retrieve. The process can take from 10 to 30 seconds. Do not rush to connect them to the phone until you see that the indicators work synchronously with the Reset method. For Xiaomi Mi True Wireless Earbuds, the algorithm may vary slightly depending on the firmware version. First option: remove the headphones from the case. Press and hold the touch panels on both modules for a period of time. 20 The indicators should blink red several times, then the headphones will turn off. Place them back in the case. Second option (for models with a button on the case): put the headphones in the case, but do not close the lid. Find the function button on the case case. Press and hold it during the course. 15-20 seconds until the indicator on the case lights up in orange. ⚠️ Warning: Do not remove the headphones from the case during the reset or open the lid (if the reset is done with the case button) so as not to interrupt the rewriting process. Delete the old headphone record in your phone and search again. Synchronize models with a button on the case (Pro, Basic 2) Newer models, such as Mi True Wireless Earbuds Basic 2 or AirDots Pro, often have a physical control button on the charging case. This greatly simplifies the process of controlling modes. To enter the pairing mode, press and hold the button on the case for about 2 seconds. The indicator should start flashing white longer. This signals that the headset is ready for the plug-in, if you need to throw the orange button before you turn on the plug-in. Action Duration Pressing Indicator Reaction Result Short press 1 sec Lights Charge Checking Long press 2-3 sec Mitches white pairing mode Holding 15+ sec Burns orange Resets Use this table as a cheat sheet when working with the case button. Different duration of pressing activates different modes of operation. Be careful not to accidentally reset the device when you just need to connect the device. Solving problems with connecting only one earphone Situation when only one is working on the phone, sometimes you don't use the second one on the device at the same time. First, let the headphones stand next to each other for 10-15 seconds outside the case. If the problem persists, check the sound balance in the phone settings. Perhaps the balance slider is shifted completely to one side, which makes it seem that the second headphone does not work. It is also worth cleaning the speaker grid, since sulfur can block the sound. Frequently asked questions (FAQ) Can you use Xiaomi headphones one at a time? Yes, most Xiaomi Mi True Wireless Earbuds models support mono mode. You can use only the left or only the right earphone independently. However, it is worthwhile to clean the speaker grid, if the indicator is synchronized in between the color, you usually have a light in between the color. If the headset does not charge at a red indicator, check the contacts in the case and on the headphones themselves for contamination. How to find out the version of the headphone firmware? To view the version of the software and update the firmware, it is recommended to use the official Mi Home or Xiaomi Earbuds application. Connect the headset to the app, and if an update is available, the system will prompt you to install it. Are the headphones compatible with the iPhone? Yes, Xiaomi's Bluetooth headsets are compatible with iOS. However, some advanced features, such as a connection pop-up or control through an app, may only be available on Android devices with shells. MIUI. Why do headphones run out quickly after synchronization? If after reset and synchronization, autonomy has dropped, perhaps one of the modules is constantly trying to find the second one, using energy. It can also be a sign of battery wear.
