Owners of Xiaomi Air 2 wireless headphones often face the need to improve the device’s performance, whether it’s eliminating channel desynchronization or adding new controls. Software updates are not just a formality, but an important process that allows you to fix Bluetooth connection errors and optimize the performance of microphones. Many users ignore notifications of new versions, not knowing that they can solve problems with sound or autonomy.
The process of updating the firmware Xiaomi Air 2 (model TWSEJ06LS) and its advanced versions, such as Air 2 Pro or Air 2s, requires a certain sequence of actions. Unlike smartphones, there is no button "Check Updates" in the phone settings. All management is carried out through a specialized application that communicates with the headphone chip directly. It is important to understand that interrupting this process can lead to incorrect operation of the device.
In this article, we will discuss in detail how to prepare gadgets, which application to use and what to do if the update hinges on a certain percentage. You will learn about the nuances of working with Mi Wear and Xiaomi Earbuds, as well as how to distinguish the original device from a fake that does not support software updates.
Why You Need to Update Your Headphone Software
Electronics manufacturers are constantly working to improve the algorithms of their devices. For Xiaomi Air 2 updates often contain patches that improve connection stability. If you notice that the sound is interrupted or the headphones spontaneously turn off, installing a new firmware can solve this problem, this is especially true for users who use the device in places with large concentrations of wireless networks.
In addition to bug fixes, updates can introduce new features or change the logic of touch control, for example, the sensitivity of touches can be adjusted or support for new codecs for audio transmission, sound quality can also be improved by software by changing the equalizer or noise cancellation during conversation.
💡
Before you start the upgrade, make sure that the headphone charge is at least 60% so that the process does not interrupt at a critical stage.
Sometimes users are faced with a situation where one headphone is quieter than another. This is a classic example of desynchronization, which Xiaomi engineers often fix in new versions of software. Regular check for updates allows you to keep the device up to date and extend its life comfortably.
- 🔊 Improved volume balance between left and right channel.
- 📡 Optimization of the antenna module for a stable signal.
- 🔋 Adjusting energy consumption algorithms to increase operating time.
- 🎙️ Improvement of noise reduction system during calls.
Preparation for the update: necessary conditions
Before proceeding with the immediate procedure, you need to make sure that all the conditions are met.The first and most important requirement is the presence of a compatible smartphone. Android devices are best for Xiaomi Air 2, although iOS is also supported with some functionality limitations.
The second critical point is the Internet connection: the smartphone must be connected to a stable Wi-Fi network or have a good cellular signal, since a firmware file can weigh several megabytes. The data is downloaded to the phone and then transmitted to the headphones. Interrupting the boot at this stage will require a fresh start.
⚠️ Warning: Don't try to update your headphones if they're in a case. Remove them and make sure they're paired with each other and your phone.
It is also worth clearing the cache of the application through which the update will be made, which will help to avoid errors in reading old configuration data. If you have previously used other applications to manage your headphones, close them completely so that they do not conflict with the update process.
Check for free space in your smartphone's memory. Although the firmware file itself weighs a bit, the system may need space for temporary files. Make sure your phone isn't in power-saving mode, which can limit background Bluetooth activity.
Choosing the Right Application for Management
One of the most common problems is software confusion. Different regions and versions of Xiaomi Air 2 may require different apps.The global headphone version usually works with the Mi Wear app, while the Chinese version (CN) often requires Xiaomi Earbuds or even Mi True Wireless Earbuds.
If you download an app and it can't see your headphones, you're probably using the wrong version of the app. Try removing the current app and installing an alternative from the official list. Sometimes setting up a region in the app settings, changing a country from Russia to China, or vice versa, can open up access to the desired features.
| Annex | Region of headphone version | Available functions | Interface language |
|---|---|---|---|
| Mi Wear | Global (Global) | Basic settings, update | Russian, English |
| Xiaomi Earbuds | China (Chinese) | Full access, equalizer settings | Chinese, English |
| Mi True Wireless | Old versions | Limited functionality | Depends on the version. |
It is important to download apps only from official Google Play or App Stores. APK-files may contain malicious code or be incompatible with the current version of your phone's operating system. Once installed, give the app all the permissions you request, especially location and Bluetooth access.
Why can't the app see the headphones?
Step-by-step instructions for updating the firmware
The upgrade process is simple enough if you follow the algorithm. First, open the installed app and wait until it detects the connected Xiaomi Air 2. The home screen should display the current firmware version and, if an update is available, the corresponding notification or button.
Press the update button. The system will ask you to confirm the action. Once confirmed, the file will start uploading to the smartphone, and then transferring the data to the headphones. At this point, the LED can often flash on the headphone indicators, signaling the process of writing data.
☑️ Checklist before update
Don't put your phone away from your headphones or open other heavy apps. While the current versions of Android and iOS are good at managing resources, it's best not to take any risks. The process can take anywhere from 5 to 15 minutes depending on the upgrade size and connection speed.
Once installed, the headphones can automatically restart, you will hear a distinctive beep or a voice message (depending on the version) confirming successful completion, check the version of the software in the application - it should change to the current one.
⚠️ Warning: If the progress bar is 99 percent frozen for more than 10 minutes, don't panic. Sometimes the final data integrity check takes a long time.
Solving problems during the update
Even if you follow all the rules, you can get errors, and one of the most common is "Update failed," or an endless download cycle, in which case the first thing you need to do is put the headphones in the case, close the lid, and wait a minute, and then remove them and try to start the process again.
If the problem persists, try uninstalling the app, restarting your smartphone, and installing the program again. Sometimes, a conflict of Bluetooth drivers in your phone's operating system interferes with the correct data transfer, and it's worth checking if flight or power saving mode is activated.
In rare cases, the problem lies in the Bluetooth module of the phone itself. Try to update from another smartphone. If the other device is successful, then it is the settings of your main phone.
- 🔄 Reset your headphones to factory settings before trying again.
- 📱 Make sure the version Android/iOS not too old on the phone.
- 🌐 Switch from Wi-Fi to mobile internet or vice versa.
- 🗑️ Clear the cache and data of the management applications.
💡
If none of the methods helps, perhaps the battery in the case is discharged - charge the case with the headphones for 30 minutes.
How to Reset Headphone Settings Before Updating
If the update causes errors or you want to start with a clean slate, it is recommended to perform a reset. For Xiaomi Air 2, the procedure is standard: place both headphones in the charging case and leave the lid open. Find the functional button on the case case case case case case case case.
Press and hold the button for 10-15 seconds. The indicator on the case should start flashing white (sometimes orange), which signals a reset, and then the headphones should be re-cooked with the phone, removing the old record from the Bluetooth list.
This procedure clears the internal memory of the headphones of temporary files and configuration errors that may have accumulated. Often this is the action that allows you to successfully install firmware that has not been installed before. After resetting and repairing, check for updates in the application again.
