How to connect Xiaomi headphones to each other: all ways and solutions to problems

Xiaomi wireless headphones have become an integral part of everyday life due to the convenience and high sound quality. When you buy or reset your headphone, one of the headphones stops syncing with the other, only works in mono mode, or doesn't connect at all, and this is especially true for Mi AirDots, Redmi Buds, Haylou, and other low-end models. TWS-headphone.

In this article, we’ll look at all the ways Xiaomi earbuds can connect to each other, from standard case sync to manual reset and use of specialized applications. You’ll learn why headphones can “unconnect”, how to return stereo sound and what to do if one of the headphones does not respond to the connection.

Important: synchronization procedure may vary depending on the firmware version and headphone model. If your model is not mentioned in the article, check compatibility in the official documentation or in the Mi Home/Xiaomi Wear app.

Why are Xiaomi headphones not connected to each other?

Before you start setting up, you should understand the causes of the problem. Most often, Xiaomi headphones stop syncing due to:

• 🔋 Discharged battery – if one of the headphones is discharged to 0%, it can “fall out” of the pair.
• 📱 Firmware failure – especially after an update through an app or an incorrect shutdown.
• 🔄 Manual resetting – if you dropped your headphones through a button on the case, they could “forget” each other.
• 🎧 Connections to different devices – for example, if the left earphone is connected to the phone, and the right – to the laptop.
• 🛠️ Mechanical damage - ingress of moisture, falls or wear of contacts in the case.

In 80% of cases, the problem is solved by rebooting the headphones or resetting to factory settings, but if the headphones are physically damaged (for example, after falling into water), repair or replacement may be necessary.

⚠️ Note: If Xiaomi headphones started to “glutch” after updating the firmware through the Mi Home app, try rolling back the software version. To do this, remove the headphones from the list of devices in the application, reset them to factory settings and connect again - the system will offer to install a stable version of the firmware.

Method 1: Standard synchronization through the case

The simplest and most versatile method is automatic synchronization via the charging case. It works for most Xiaomi models, including Mi AirDots, Redmi Buds and Haylou GT1/GT2.

1. Place both headphones in the charging case and close the lid.
2. Wait 10-15 seconds – during this time, the headphones should identify each other.
3. Open the case cover. The headphones should automatically turn on and sync (this is indicated by the flashing of the indicators on both headphones).
4. Connect your headphones to your phone via Bluetooth. If sync is successful, one device will appear in your Bluetooth settings (e.g., Mi True Wireless Earphones 2, not two separate headphones).

If the headphones flash alternately (left, then right), it means that the synchronization failed. In this case, move on to the next method.

Both earphones are charged (minimum 30%)

Case charged (indicator lit green or white)

Headphones clean (no dirt on contacts)

Method 2: Manual pairing through a button on the case

If automatic synchronization doesn’t work, try forcefully resetting the connection and manually pairing, a technique that works for most Xiaomi models, except the newest ones (like the Xiaomi Buds 4 Pro, where reset is done via an app).

Instructions:

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the back of the case (usually located under the charge indicator) for 10-15 seconds until the indicator flashes red and white (or only red, depending on the model).
3. Release the button. The headphones will drop to factory settings.
4. Get the headphones out of the case – they should automatically turn on and synchronize (the indicators will flash synchronously).
5. Connect your headphones to your phone via Bluetooth, and one name should appear on the list of devices (e.g. Redmi AirDots 3).

If the headphones are still out of sync after reset, check:

• 🔌 Contacts in the case -- maybe they're contaminated or oxidized.
• 📲 Firmware version - outdated software can cause malfunctions. Update your headphones through the Mi Home app.
• 🔋 Headphone charge – if one of them is discharged below 10%, synchronization may not work.

💡

If the button on the case does not respond to pressing, try using a paper clip or toothpick to press carefully - sometimes the contacts of the button "drown" due to mechanical wear.

Method 3: Synchronize with Mi Home/Xiaomi Wear

For some models (e.g. Xiaomi Buds 3 Pro, Redmi Buds 4), a standard case button reset may not work, in which case the synchronization should be run through the official application:

1. Install the Mi Home app (for older models) or Xiaomi Wear (for newer ones) from Google Play or the App Store.
2. Open the app and sign in to your Xiaomi account (or sign up).
3. Click Add Device (+) → Select Headphones category → Find your model in the list.
4. Follow the instructions on the screen. You usually need to:

Once you've successfully connected, the headphone control panel will appear in the app.

• Update the firmware (Section Update).
• Reset the settings (Reset or Recovery section).
• Check the synchronization status (Device Status section).

If the application shows an error Failed to connect headphones or the Device does not respond, try:

• 📱 Reboot phone – sometimes Bluetooth crashes are linked to the operating system.
• 🔄 Remove headphones from the list of conjugate devices in Bluetooth settings and connect again.
• 🌐 Change the region in the Mi Home app to China (sometimes new firmware first appears there).

Method 4: Manual synchronization via Bluetooth (for power users)

If Xiaomi headphones are defined in Bluetooth settings as two separate devices (e.g. Mi). AirDots_L mi AirDots_R), You can try to sync them manually, and this method is suitable for models that support dual connectivity (e.g. Redmi AirDots). 3 Pro).

Instructions:

1. Open Bluetooth settings on your phone and remove both headphones from the list of conjugated devices.
2. Take the headphones out of the case and wait until they start flashing (search mode).
3. In Bluetooth settings, click Device Search and wait until both headphones appear (... L and... R).
4. Connect the right earphone (... R) first. Once connected successfully, it should automatically start looking for the left one.
5. Wait 10 to 20 seconds — the left earphone should connect automatically, and if that doesn't happen, manually select it from the list of devices.

After successful synchronization, one device should remain in the Bluetooth list (without consoles _L/_R). If the headphones are still displayed separately, try it:

• 🔄 Reboot your phone – sometimes the Bluetooth system freezes".
• 📱 Update the firmware headphones through the Mi Home app.
• 🛠️ Reset the network settings on your phone (in extreme cases).

⚠️ Note: Some Xiaomi models (such as Mi True Wireless Earphones 2 Basic) do not support manually connecting individual headphones, in which case, trying to connect them separately can lead to a complete loss of sync, and you will need to reset through the case.

Frequent mistakes and their solutions

Even after successful synchronization, Xiaomi headphones may not work properly, and consider the most common problems and ways to fix them:

1.One earphone does not reproduce sound (mono mode)

If the sound comes from only one headphone, check:

• 🎵 The sound balance in the phone settings (sometimes it gets 100% one way).
• 🔋 Headphone charge – if one is discharged, it can automatically shut down.
• 📱 Bluetooth Settings – Some phones (such as Xiaomi or Redmi) have an Audio Duplex option to enable.

2.The headphones are constantly disconnecting

If the synchronization resets after a few minutes, try:

• 📵 Turn off power saving for Bluetooth in phone settings.
• 🔄 Update the headphone firmware through Mi Home.
• 🛠️ Reset the network settings on your phone (in extreme cases).

3.The headphones plug in, but the sound is interrupted

The problem may be related to:

• 📶 Bluetooth interference – move away from sources of interference (Wi-Fi routers, microwaves).
• 🎧 Bluetooth codecs – in the settings of the phone developer, select the codec SBC or AAC ptX.
• 🔋 Low case charge - some models begin to "glutch" when the case charge is below 20%.

💡

If Xiaomi headphones are still out of sync after all the manipulations, the problem may be in the hardware (damaged contacts, dead battery).
