How to connect wireless headphones Xiaomi: instructions for all models

Xiaomi wireless headphones are some of the most popular TWS-The headsets are on the market due to the combination of price, sound quality and functionality, but many users face a problem: after buying or resetting the headphones stop working in stereo mode, only one of them connects, or synchronization errors occur. This article will help you understand how to properly connect Xiaomi wireless headphones, regardless of the model – whether it is a budget Redmi AirDots or flagship Xiaomi Buds 4 Pro.

Synchronization process TWS-Xiaomi’s True Wireless Stereo is usually automated, but sometimes requires manual intervention, and we’ll look at standard connection methods, features of different models, and common bugs and solutions. Particular attention will be paid to the nuances that the manufacturer often does not keep in official instructions - for example, how to reset the headphones to the factory, if they "disconnected", or what to do if one headphone is not determined by the system.

It's important to understand that the binding algorithm can vary depending on the generation of the chipset, the firmware version, and even the operating system of your smartphone, so we structured the material so that you can quickly find a solution for your particular situation, from basic synchronization to the recovery of a dead earpiece.

Why Xiaomi headphones do not communicate with each other: the main reasons

Before you start setting up, it’s worth figuring out why Xiaomi headphones might lose touch with each other.

• 🔋 Battery discharge – if one of the headphones is completely discharged, it may not turn on or sync with the paired device.
• 📱 Failure of firmware - after updating or incorrectly disconnecting the headphones can "forget" each other.
• 🔄 Manual shutdown of stereo mode – some models (for example, Xiaomi Buds 3 Pro) allow you to use headphones separately, which can knock down the settings.
• 📡 Interference from other devices – if several Bluetooth devices are running nearby at 2.4 GHz, this can interfere with synchronization.
• 🛠️ Mechanical damage – falls or moisture sometimes disrupt contacts inside the body.

Interestingly, 80 percent of the time, the problem is solved by simply resetting your settings or rebooting your headphones, but if you encounter a bug regularly, it could indicate a hardware defect, like a Bluetooth module malfunctioning in one of your headphones, and you should contact your service center, especially if the warranty is still in place.

⚠️ Note: If Xiaomi headphones previously worked in pairs, but after connecting to a new device stopped synchronizing, the problem may lie in the conflict of Bluetooth profiles. Try to remove the headphones from the list of conjugated devices on all gadgets they previously connected to.

The standard way to bind headphones Xiaomi: step-by-step instructions

Most Xiaomi models (including Redmi AirDots 2/3, Mi True Wireless Earphones 2 and Xiaomi Buds 3/4) sync automatically when first turned on. However, if the headphones have already been used or have been reset, manual tuning will be required.

1. Put both earbuds in a charged case and close the lid for 10 to 15 seconds, which will reset the current connection settings.
2. Take both earbuds out of the case at the same time, and they should flash white or red (depending on the model) — this is a signal to find a connection.
3. On your smartphone, turn on Bluetooth and find headphones in the list of devices (usually they are displayed as Mi True Wireless, Redmi AirDots or the like).
4. Connect to the headphones. If synchronization is successful, you will hear an audible beep in both headphones, and in the Bluetooth settings, the status of Connected to media audio will be displayed.

If the headphones are connected, but the sound comes from only one, try the following:

Make sure both earphones are charged (indicators are green)

Reboot Bluetooth on your smartphone (turn off/on)

Check the sound balance in your phone settings (sometimes 100% down in one channel)

Update the firmware of headphones through the Mi Home app or Xiaomi Wear-->

Models with single-mode support (such as the Xiaomi Buds 4 Pro) may require an additional action: once connected, press the touchpad on the right earphone for 3 seconds to activate the stereo mode.

💡

If Xiaomi headphones are not defined by your phone, try connecting them to another device (tablet or laptop) to help you understand if the problem is in the headphones or in your smartphone.

Synchronization Features for Different Xiaomi Models

Although the general principle of binding TWS-The headphones are the same, the different Xiaomi lines have nuances. We put them together in a table for convenience:

For example, Xiaomi Buds 4 Pro is critical to use the branded application Xiaomi Wear, as it not only controls synchronization, but also updates the firmware of the headphones. Without it, some functions (such as transparent mode or customization of gestures) can work incorrectly.

Redmi AirDots 3 Pro, on the other hand, often suffers from the monosound effect of connecting to an iPhone, which is due to the Bluetooth implementation of iOS, and the solution is simple: first connect your headphones to your Android device, wait for synchronization, and then connect to your iPhone.

⚠️ Attention: Xiaomi headphones with support LDAC (For example, Xiaomi Buds 4 may not sync with Android devices below version 8.0!

How to reset the settings of headphones Xiaomi to factory

If standard methods don't work, you'll have to do a hard reset, which removes all the connections you've saved and returns the headphones to their original settings, and it depends on the model.

Redmi AirDots (all generations) and Mi True Wireless 2:

1. Put both headphones in the case and close the lid.
2. Press and hold the button on the back of the case for 15-20 seconds until the indicator flashes red and white.
3. Get your headphones out – they should automatically go into pairing mode (blinking white light).

For Xiaomi Buds 3/4 Pro and Redmi Buds 4:

1. Make sure that the headphones are at least 30% charged.
2. Press the touch panels on both headphones simultaneously for 10 seconds until you hear the reset beep.
3. Place the headphones back in the case, then remove - they should sync again.

Once reset, Xiaomi headphones will appear in the list of Bluetooth devices as a new device (e.g., LE-Mi True Wireless).

Synchronization problems after firmware update

One of the most common complications is the loss of communication between the headphones after a firmware update, which is due to the fact that newer versions of firmware sometimes change the connection protocols, for example, after upgrading to version 1.4.0.7, many users of Xiaomi Buds 3 Pro complained about constant connection breaks.

Here's how to solve the problem:

• 📲 Firmware rollback – if the update caused a crash, you can return the previous version through the Xiaomi Wear app (Update section) → Back to the factory version).
• 🔄 Manual Resynchronization – Remove the headphones from the list of Bluetooth devices and connect them again.
• 🛠️ Reset via Engineering Menu – for advanced users: connect headphones to PC via ADB The command is: adb shell am start. -a android.bluetooth.device.action.PAIRING_REQUEST -e android.bluetooth.device.extra.DEVICE"MAC-headphone" (MAC-The address can be found in Bluetooth settings).

Critical nuance: if after updating the firmware headphones Xiaomi Buds 4 Pro ceased to support the codec AAC, It's not a bug, it's a feature of the new version of firmware. LC3 improve energy efficiency.

If none of these methods worked, check to see if new firmware versions have appeared. Sometimes Xiaomi releases patches to fix sync bugs within 1-2 weeks of the main update.

💡

Before updating your headphone firmware, always check other users' reviews on forums (such as 4PDA or Mi Community). If you complain about problems, you better wait with the update.

How to check if the headphones are synchronized correctly

It's not always obvious that Xiaomi headphones are in stereo mode. Here's how to check it out:

1. Turn on the music and turn your finger over each earpiece, and if the sound is only lost in the closed ear, the synchronization works.
2. In Bluetooth settings, click on the headphone name and check the status: Stereo or A2DP should be indicated (not Mono or HFP).
3. Use the sound test in the Xiaomi Wear app (headphone settings → Sound check).

If one of the headphones has a quieter or no sound at all, try:

• 🔊 Check the sound balance in the smartphone settings (on Android: Settings) → Sound. → Stereo balance).
• 🧹 Clean the speaker mesh of earwax (use a soft brush or vacuum cleaner).
• 🔋 Make sure both earbuds are charged the same (difference in charge level can affect volume).

⚠️ Attention: Xiaomi Buds 3 Pro and newer headphones use dual speaker technology (low and high frequency). If one of the speakers does not work, the sound will appear "empty." This is not a synchronization problem, but a hardware defect.

Frequent Errors and Their Solutions: Checklist for Users

We have collected typical synchronization problem scenarios and ways to fix them:

If your problem doesn’t make it to the table, try an alternative connection method:
