The situation when TWS-Xiaomi headphones stop working in pairs and one of them is silent or plays the sound separately, familiar to many owners. This is a common problem caused by desynchronization of Bluetooth modules, a software failure or the discharge of one of the batteries. Users often think that the device is out of order, but in most cases, the gadget can be returned to full operation without visiting the service center.
Reestablishing the connection between the left and right earphone requires a certain sequence of actions that depends on the specific model and type of operating system of your smartphone. It is important to understand that desynchronization is a software conflict that is solved by forcing devices to pair with each other before connecting to the phone. Ignoring the right steps can lead to the problem returning after a few days of use.
In this article, we will discuss in detail the algorithms for different headphone series, methods of complete reset and methods of troubleshooting. You will learn how to correctly use touch controls and physical buttons to reinitialize Bluetooth connection. Following the instructions will save you time and budget by returning your favorite accessory functionality.
Reasons for desynchronization of TWS-headphones Xiaomi
Before you start to act, you need to understand the nature of the problem, and most often, headphones work separately because they have forgotten each other and try to connect to the sound source as two independent devices, which often happens after upgrading the firmware of the smartphone or the battery of one of the headphones to a critical level.
Another reason could be a Bluetooth profile conflict, and if you've previously connected a headset to another phone or tablet, the data might have mixed up, and it's also worth checking the charging case: if contacts get contaminated or oxidized, one of the headphones might not have charged, and you're taking the discharge for a breakdown.
Why is this happening with Xiaomi?
True Wireless Stereo's algorithms are implemented differently from one manufacturer to another. Xiaomi often uses a Master-Slave scheme, where one headphone receives a signal from the phone and transmits it to the second. If the communication between them is broken, the second channel is silent. In newer models with Mirroring technology, the role of the wizard can switch, which sometimes causes software failures when switching sources.> Do not rule out the influence of third-party applications. Some sound management programs or bass "improvers" can intercept control of the communication channel, disrupting the stability of the work of the second channel. In newer models, the role of the master can switch, the switch can be switch on the smartphone, you need to immediately remove the switch from the memory before you start. Go to your device’s wireless network settings and find the name of your headphones in the list of previously connected devices. Click on the gear icon or the “i” icon next to the model name and select Forget the device or Disable it. This is a critical step, as as long as the phone remembers the old connection settings, the new synchronization between the headphones may not go through correctly. ☑️ Preparation for recovery Put headphones in the caseClose the case cover on 10 Seconds Turn Bluetooth on your phone Remove the device from the list of "Forgotten devices" Completed: 0 / 4 After removing the device, make sure both earbuds have a sufficient charge. Put them in the case and connect it to charging at least on the back of the headphone. 15-20 Low charge is often the hidden cause of unstable operation of communication modules that simply cannot reach full capacity to search for a “partner». Many popular models, such as the Redmi AirDots 2, Mi True Wireless Earbuds Basic 2 or AirDots 3 Pro, have a functional button on the case charger case. This button is designed specifically to reset the settings and transfer the headphones to pairing mode. First, place both headphones in the case and leave the lid open. Press and hold the functional button on the case for 10-15 seconds. The Pair flashes on the new color mode, and start to search for a full color of the device. Wait until the indicators on the headphones themselves (if any) or on the case start flashing in the rhythm characteristic of the standby mode of connection. Now open the Bluetooth list on your smartphone and find a new device. If it goes well, there will only be one headset name on the list, not two of the same. Click on it to connect. Setting up models without a button (Redmi AirDots, Mi Twins) In budget models like Redmi AirDots or early Mi Twins, there is no physical button on the case. This uses the method of resetting the earbuds through the touchpads, which requires more precision and patience. Remove both earbuds from the case. Press and hold the touch zones on both earbuds simultaneously for a period of time. 5-7 Then press the sensors again and hold them, but now wait around. 20 seconds. The lights should light up red and then start flashing white quickly. Once both lights blink, put the headphones back in the case, close it and wait. 5-10 Then pull them out again, and they have to automatically find each other, and usually one of the headphones blinks slowly (standby mode), and the other one stops blinking or changes rhythm, which means pairing up, and then you can search for the device in the phone's Bluetooth menu. If you see two devices with the same name, then the synchronization did not go, and you need to repeat the reset procedure. 3 Pro, 4 Pro and Xiaomi Buds 4 have more complex logic and often require the use of the proprietary application Xiaomi Earbuds (or Mi Home) for full customization. If a standard reset doesn't work, use the software method. Connect your headphones to your phone (even if the sound is only on one side). Open the Xiaomi Earbuds app and find your headphones in the list. In the device menu, find the Settings or Systems section and select the Resettings option. The app will automatically execute all the necessary commands to flash the communication configuration. Once the process is complete, the headphones will reboot. This method is most reliable, since the app controls the firmware version and can update it if bugs are detected.

Also check the sound balance in the phone settings. Go to Settings → Sound and vibration → Channel balance L/R. Sometimes, after updating the system, the slider may shift towards one channel, making it seem that the second headphone is not working. Try connecting the headphones to another device (another smartphone, tablet or laptop). If another device still has a problem, it means it's a malfunction inside the headset. If it works, look for the reason in your main phone's Bluetooth settings. In rare cases, "deep discharge" helps. Leave the headphones off the case on until the battery is completely depleted until they turn off. Then charge them completely in a closed case. This can restart the power controller. Frequent questions and problems (FAQ) Why does a phone see two devices with the same name? This means that the headphones are not synchronized with each other and work in mono mode. You need to perform a full reset (Hard Reset) according to the instructions for your model, so that they again “find” each other and combine into a stereo pair before connecting to the phone. Can you use Xiaomi headphones with an iPhone? Yes, they work on the standard Bluetooth protocol. However, the functionality of the Xiaomi Earbuds application on iOS is limited or not available, so reset and adjust the balance sometimes only through standard buttons and sensors, without the help of software. What to do if only one indicator burns? Most likely enter the second one after a long connection, you do not even get into the battery after you clean the battery. This is usually done by pressing the touchpad or the case function button for a long time (about 5-7 seconds) until the color or rhythm of the indicator blinks changes.
