Update firmware Xiaomi Buds 3 Pro: the full guide

Owners of the Chinese giant’s premium wireless headphones often face the need to update software. For the Xiaomi Buds 3 Pro, this process is critical, as the company’s engineers regularly release patches that fix bugs and improve the operation of the active noise cancellation system. Many users do not know that without fresh software, the device will not reach its full potential.

The upgrade process does not require complex equipment or special skills. You only need a smartphone with a companion application installed and a stable Internet connection. The firmware is transmitted over a Bluetooth channel, so interruption of communication can lead to errors. In this guide, we will discuss all the nuances of the procedure to make your headphones work perfectly.

It's worth noting that newer versions of software often add support for new codecs or optimize microphones during calls. Ignoring update notifications can deprive you of improvements in sound quality. Let's look at how to properly prepare the gadget and perform the installation.

Why you need to update the headphone software

Modern. TWS-Headphones are complex computers encased in a miniature case, and developers are constantly working on sound processing algorithms, and each update brings with it important changes. Xiaomi Buds 3 Pro is characterized by the presence of hybrid noise reduction, the setting of which is often adjusted by engineers after the release of the device.

The main reasons why you should follow the software versions:

• 🎧 Improved sound quality and frequency balancing for drivers.
• 🔋 Optimizing energy consumption and increasing battery life.
• 📡 Stabilizing Bluetooth connections and eliminating channel dissynchronization.
• 🎤 Adjustment of the noise reduction system in windy weather.

⚠️ Warning: Installing old or modified firmware can permanently disable your headphones. Use only official refresh channels.

Often users notice that after the upgrade, the headphones start to hold the charge better, this is the result of optimizing the controller's background processes, and small bugs can also be corrected, such as spontaneously turning off when the charge level is low or problems with the wear sensor.

Preparation for the installation of a new version

Before you start, you need to make sure that all the conditions are met, which minimizes the risk of errors, first check the charge level in the case and the headphones themselves, if the battery is discharged, the process can be interrupted in the middle, which will lead to unpleasant consequences.

The second important aspect is the app. To work with Xiaomi Buds 3 Pro in the global version, the best use is the Xiaomi Earbuds or Mi Wear app. In China, the Xiaomi Buds app is used, but it can require the Chinese region in the phone settings. Make sure the app has all the necessary permissions, especially access to geolocation and Bluetooth.

It is also recommended to close the background apps on your smartphone so that the system does not try to save energy and break the connection at a critical moment.Put the phone next to the case, but do not put it on working microwave ovens or routers that cause interference.

Method 1: Update via Mi Buds

This is the basic and most reliable method for most users. The interface of the app is intuitive, and the system will tell you if a new version is available. First, open the app and make sure the headphones are connected. The connection status should be displayed on the home screen.

Follow the algorithm further:

1. Click on the image of your Xiaomi Buds 3 Pro in the list of devices.
2. In the menu that opens, find the “Settings” item or the gear icon.
3. Select the "Firmware Update" section.
4. If the system finds a new version, the “Update” button will appear.

Once you press the button, the data packet will start loading, which can take 1 to 5 minutes depending on the speed of the Internet, then the firmware process will start, at which time the case indicator can flash an LED, and the application will display the progress bar.

Method 2: Use of the Mi Wear app

Mi Wear is often used as a universal control center for the Xiaomi ecosystem, and the principle of operation is similar, but the interface may differ.

You need to go to the device profile. This is usually done by a long tap on the headphone card or through the control menu. The device information section often contains an update check button. Click on the firmware version several times or find the appropriate item in the About Device menu.

It is important not to lock the smartphone screen during the process. Android or iOS system can limit the background activity of the application, which will lead to a connection timeout. Keep the screen on and monitor the installation progress.

Possible mistakes and ways to solve them

Even if all the rules are followed, there may be failures, most often users encounter an error “Disconnected” or “Download interrupted”, this may be due to unstable Bluetooth signal or conflicting versions of the application.

If the process is held at a certain percentage:

• 🔄 Don’t panic or open the case immediately.
• 📱 Check if the phone is power saving.
• 🔌 Try to put the case on charge (sometimes this stabilizes the power supply).
• 🗑️ In extreme cases, wait for time out and try again.

💡

If the update is 99% down, try turning off the internet on your phone after you have finished downloading the file, but before you start installing it, which sometimes helps to avoid problems with the verification server.

A common problem is to de-synchronize your left and right earphones after upgrading, in which case a factory reset will help, and press the touch pads on both earphones simultaneously for 10-15 seconds until the indicator lights up in orange.

Impact of firmware on sound quality

Many audiophiles argue about whether the firmware changes sound. In the case of Xiaomi Buds 3 Pro, the changes are really noticeable. Updates often affect the equalizer and spatial audio algorithms. Once a new version is installed, the sound can become more detailed or, conversely, softer.

In some cases, users notice that the transparent mode is changing, and it can become more natural, with less digital noise, as a result of fine-tuning the microphones in the environment.

Remember, audio codecs can also get patches, and support for LDAC or AAC codecs can be more stable after upgrading the headphone system software, especially for Android smartphone owners who value high-quality data transfer.

Resetting settings after update

Sometimes, after a successful new version is installed, a complete reset is recommended, which helps clear the cache of old settings that may have conflicted with the new software.

Put the headphones in the case and open the lid. Find the function button on the case case. Hold it for 20 seconds until the indicator flashes white three times.

⚠️ Warning: After resetting, all your personalized equalizer and gesture settings will be deleted.

This procedure often solves problems with a “floating” connection, where the headphones themselves turn off or switch between devices without a user command.
