How to combine two headphones Xiaomi in one set: 5 proven ways

Xiaomi wireless headphones have long been the standard for millions of users, thanks to a combination of price, quality and functionality. But what if you lost one headphone from a set or bought two identical headphones separately? The question of pairing them into a single pair becomes critical — without proper synchronization, you can not use stereo or microphone.

In this article, we will discuss all the current ways to connect two Xiaomi headphones, from standard methods through a mobile application to manual manipulation of buttons. We will focus on AirDots, Buds and FlipBuds models, but the principles will work for other lines. Importantly, the procedure may differ depending on the firmware version and model, so we will give universal solutions and unique combinations of buttons for resetting that are not documented in the official instructions.

Why aren’t two Xiaomi headphones connected?

Before you try to hide your headphones, you need to understand the cause of the problem, and most often, a couple breaks up because of:

• 🔋 Battery discharge of one of the headphones (even if the indicator is on, the charge can be critically low for synchronization).
• 📱 Firmware failure after incorrect update via Mi Home or Xiaomi Wear app.
• 🔄 Manual resetting of settings on one of the headphones (for example, after a long hold of the button).
• 🛠️ Hardware damage – oxidation of contacts in a case or damage to a Bluetooth antenna.

If the headphones have previously worked together but suddenly stopped syncing, start by rebooting the case: remove both earphones, close the lid, wait 10 seconds and try again. In 30% of cases, this solves the problem without additional manipulation.

⚠️ Note: If one of the headphones connects to the phone as a monopod (for example, only Mi True Wireless Earphones (L) is displayed), this means that the pair is torn at the firmware level.

Method 1: Sync with Mi Home/Xiaomi Wear

The official method from Xiaomi involves the use of proprietary software. This method is suitable for most models released after 2020 (AirDots 2/3 Pro, Buds 3/4, FlipBuds Pro, etc.).

Step-by-step:

1. Install the Xiaomi Wear app (for new models) or Mi Home (for older ones) from Google Play or the App Store.
2. Place both headphones in the case and close the lid for 5 seconds, then remove them.
3. In the app, go to Devices → Add Devices → Headphones.
4. Choose your model from the list. If you don't have one, choose Other Xiaomi headphones.
5. Follow the instructions on the screen. During the synchronization phase, hold the button on both headphones for 10-15 seconds (until the white and red lights flash).

If the app doesn't see headphones, try:

• 📵 Disable Bluetooth on your phone, restart it and try again.
• 🔄 Reset network settings on your phone (Settings) → System system → Reset → Reset Wi-Fi, mobile network and Bluetooth).
• 🔋 Charge the case to 100% - some models block synchronization with a low battery charge case.

Method 2: Manual button pairing (for models without an application)

If your model is not supported by Mi Home (such as AirDots Youth or Mi Basic), you can use the hardware method.

Algorithm of action:

1. Remove both earphones from the case.
2. Press and hold the touch button on the right earphone for 20 seconds until the indicator starts flashing red and white alternately.
3. Repeat step 2 for the left earpiece.
4. Place both headphones back in the case and close the lid for 10 seconds.
5. Get your headphones out – they should automatically sync (the indicators will light up white and start to pulsate slowly).

If the lights keep flashing randomly, it means the earbuds don't recognize each other.

⚠️ Note: On AirDots 3 Pro and later, after a reset, you may need to re-assign to your Xiaomi account via the app. Without this, the headphones will not save the settings after being removed from the case.

Method 3: Resetting through AT-Teams (for advanced users)

If standard methods do not work, you can try low-level reset through AT-This method requires an Android smartphone with Bluetooth support. HCI Snooper and root rights (or ADB-access).

Instructions:

1. Install the nRF Connect or Bluetooth Commander app on your phone.
2. Connect to the headphones in Developer Mode (this may require you to enter the command adb shell am start -n com.android.bluetooth/.opp.BluetoothOppLauncherActivity).
3. Send sequentially commands: AT+RESET AT+DEFAULT AT+PAIR=1
4. Reset the headphones (hold the 10 seconds button).

This method works on AirDots 2 and Buds 3, but can cause firmware failure on new models. Use it only if other methods have not worked.

💡

Before shipment AT-commands make a backup of headphone settings through the Xiaomi Wear app (section "Settings" → Backup").

Method 4: Update firmware via PC

If the headphones don't sync because of outdated firmware, you can update it manually through your computer.

• 💻 Windows/Mac Bluetooth 4.0+
• 🔌 Cable USB-C (case-supported wired update)
• 📁 Firmware for your model (download at xiaomifirmware.com)

Step-by-step process:

1. Connect the case to the PC via USB (on some models you need to hold the button on the case for 5 seconds to activate the update mode).
2. Run the Mi Flash Tool or QFil utility (depending on the model).
3. Select the firmware file (.bin or.fw) and press Start.
4. Wait until the case is completed (don't turn it off!) The headphones will automatically reboot and sync.

After updating the firmware, it may be necessary to re-pair the phone unless the case is defined as USB-device, try it out:

• 🔌 Use a different cable (original from Xiaomi).
• 🖥️ Reinstall Qualcomm QDLoader drivers.
• 🔄 Reboot the PC and the case (hold the button on the case for 20 seconds).

Method 5: Hardware diagnostics (if nothing helps)

If the software methods did not give a result, the problem may lie in the hardware:

• 🔋 Case contacts - clean them with alcohol and cotton swab (oxidation prevents charge and synchronization).
• 📡 Bluetooth antenna -- AirDots headphones, it's under a rubber pad, and if the pad is damaged, the signal weakens.
• 🔧 Microphone -- on some models (Buds 3 Pro), the microphone is involved in the synchronization process. If it's clogged, the headphones don't recognize each other.

To check the hardware serviceability:

1. Try plugging each earphone individually into your phone, and if one of them isn't identified at all, it's the problem.
2. Light a flashlight in the case connector: if the contacts are blackened, they need to be cleaned.
3. Check if the headphone lights up when you press a button, and if it doesn't, you might break the circuit.

⚠️ Note: If the headphones still don’t sync after cleaning the contacts and the indicators are lit in a non-standard color (for example, green), this may indicate damage to the Bluetooth controller.

💡

Before contacting the service, check the headphones on another phone - sometimes the problem lies in the Bluetooth module of the smartphone, not in the headphones themselves.

Frequent Mistakes and How to Avoid Them

When trying to stitch up headphones, users often make common mistakes that lead to even bigger problems.

• ⏳ Insufficient button holding time – many release it after 5-7 seconds, although it takes 15-25 seconds to reset (see table above).
• 🔋 Different Charge Levels – If one earphone is 100% charged and the other is 20% charged, synchronization may not occur.
• 📱 Use of informal firmware – custom firmware often breaks the pairing algorithm.
• 🔄 Interrupting the process – if you interrupt the reset (for example, insert the headphones back into the case before the blinking is complete), they may stop turning on.

To minimize the risks:

• 📋 Keep an action log – record which buttons and in what sequence you pressed.
• 📹 Film the process on video – this will help you to repeat successful steps or show them in the service.
• 🔍 Check the firmware version in the Xiaomi Wear app before updating.
