Modern wireless headphones are complex microcomputers that require regular maintenance to work. Owners of the popular Xiaomi Air 2 SE model often face the need to improve communication quality or eliminate software errors that can accumulate over time.
The firmware process may seem complicated for the untrained user, but Xiaomi has tried to simplify the process as much as possible. You do not need complex cables or special computer programs, since all the work is done through a smartphone.
In this article, we will take a look at all the stages of preparation and the update process, learn how to connect the device correctly, where to download the current version of the software and what to do if the process went wrong. Careful reading of the instructions will help avoid common errors that often lead to malfunctions in electronics.
Preparation for software updates
Before you start any manipulation with the system software, you need to make sure that the equipment is ready. Battery charge is a critical parameter: if the headphones or phone run out during the recording process, this can lead to irreversible damage to the firmware. Make sure that the case and the headphones themselves are charged at least 50-60%, and the smartphone has a sufficient supply of energy.
It is also important to check the stability of the Internet connection on your mobile device. Firmware files can weigh several megabytes, and when the connection is interrupted, it is best to use a reliable Wi-Fi network, as a mobile 4G/5G signal in the room can be unstable.
⚠️ Note: Do not try to update your headphones if you are in a low-reception zone or in moving vehicles where the connection to the base station can switch frequently.
Make sure your smartphone has the latest version of the Mi Wear app (formerly called Xiaomi Earbuds). Older versions of the software may not properly display the status of the device or simply not see the new firmware version. Update of the app itself often contains bug fixes that interfere with normal interaction with accessories.
It is not superfluous to clean the contacts on the headphones themselves and inside the case. Oxidation or dust can interfere with normal data transfer and charging during a long refresh process. Use a dry cotton swab to clean metal areas carefully.
Necessary tools and applications
To successfully install the new version of the software, you will need a minimum set of tools that you most likely already have at your fingertips, the main tool being a smartphone based on the Android or iOS operating system, which will be used to download and transfer data to headphones.
- 📱 Smartphone with Mi Wear or Xiaomi Earbuds app installed – the main control panel.
- 🎧 Headphones Xiaomi Air 2 SE and charging case - object of update.
- 🔌 Type-C charging cable – to provide power to the case in the process.
- 💡 Stable light source – to see status indicators on the case.
It’s important to note that for iPhone users, the app’s functionality may be somewhat limited compared to Android devices. However, the basic firmware update feature is available on both platforms. If you have Android, make sure the app has all the necessary permissions, especially for Bluetooth and geolocation, as without this, you can’t find the device.
In some cases, you may need Bluetooth Scanner or similar diagnostic software if you don't find it by standard methods, but this is rarely required and only if you have serious pairing problems. In normal operation, there is enough regular Mi Wear functionality.
Step-by-step instructions for updating with Mi Wear
The process of installing the new version of the software is automated and does not require the user to have deep technical knowledge. All you need to do is follow the instructions on the screen and not interrupt the process ahead of time. First, open the Mi Wear app on your smartphone and wait until it finds the connected headphones.
The home screen displays your current battery and connection status. If an update is available for your device, a notification will appear next to the headphone image or in the settings section, usually a red dot or button with the text "Update available." Click on it to get to the details.
☑️ Checklist before update
In the window that opens, you will see the version of the new firmware and the changelog. Read carefully what has been fixed or improved. If you are satisfied with the change list, click Download or Update.
Once downloaded, the installation process will begin, at which point the smartphone screen may go out or go into lock mode, but the application will continue to work. Do not force the application to close and try to keep the phone next to the headphones. The indicator on the case may start flashing white, signaling the recording process.
⚠️ Warning: It is strictly forbidden to open the case lid or remove the headphones while the indicator blinks, this will interrupt the flow of data and may lead to "bricking" of the device.
When the process is complete, you will hear audible confirmation in the headphones or see a message of success on the phone screen. The headphones can automatically restart, then it is recommended to reconnect them to the phone again to make sure that all functions work correctly.
Solving Connection and Installation Problems
Despite the simplicity of the procedure, there may be some crashes. If the update hangs at a certain percentage or the button is inactive, try a series of actions. First of all, check if the Bluetooth channels are mixed up. Sometimes the phone "thinks" that the headphones are connected, but the data channel is occupied by another application.
Try "forgetting" the device in your phone's Bluetooth settings, and then pairing again through the app. This resets the connection cache and often solves the "invisibility" problem of the new firmware. It also helps to completely reboot the smartphone, which clears temporary files of system services.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Update button gray | No internet or weak signal | Switch to Wi-Fi network |
| A mistake at 30-50% | Unstable Bluetooth signal | Bring the phone closer to the case |
| Headphones are not visible. | Failure to pair | Make reset to factory settings |
| The indicator is burning red. | Low battery charge | Put the case on the charger. |
If nothing works, do a full reset of the headphones. To do this, place them in the case, open the lid and press the functional button on the case case case on the case. 10-15 The indicator should flash white several times. Then try to connect them as a new device.

Customization of sound after firmware update
When you successfully install new software, you often change the sound processing algorithms. Codecs may work differently, so you should recheck the equalizer settings. Mi Wear has a basic equalizer that allows you to customize the sound to your taste.
Note the Game Mode feature, which can be optimized for lower latency in newer versions of the firmware. If you play mobile games, be sure to activate this switch in the app menu, which will reduce the latency between video and sound.
Also check the touch control. After the update, the sensitivity of the touch panels may change. Test single and double presses. If they work incorrectly, try reconfiguring them in the app menu or rubbing the surface of the headphones, as skin fat can interfere with the sensor.
💡
If the sound is quieter after the update, check the absolute volume settings in the “Developers” section on Android or simply turn up the volume on the phone and in the app.
