How to connect two headphones Xiaomi Earbuds with each other: the complete guide

Did you get your Xiaomi Earbuds out of your case and only sound in one headphone? Or did the devices stop syncing after the firmware update? This problem is familiar to many owners of Xiaomi wireless headphones, from the budget Redmi Airdots to the flagship Buds 4 Pro. Most often the fault is the pairing failure between the left and right modules, less often hardware malfunctions.

In this article, we will analyze all the working ways of connecting two Xiaomi Earbuds headphones with each other: from a standard reset to hidden functions in the Mi app. Fit/Xiaomi Wear. You'll learn how different procedures are for different models, what to do if the headphones aren't determined by the phone, and how to avoid repeated crashes. QCC3040 (Like Buds. 3 Pro where synchronization can be blocked due to firmware conflict.

Before you start the instructions, check the obvious: both earbuds are charged (the indicators on the case are white/green), and there are no restrictions on connecting new devices in your smartphone’s Bluetooth settings.

Why Xiaomi Earbuds Headphones Aren’t Connected

Xiaomi’s headphones are desynchronized into two groups: software and hardware. 80% of the time, the fault is a pairing protocol failure, when one of the headphones (usually the right-handed one) loses communication with the slave module.

• 🔋 A discharged battery of one of the headphones (even if the case shows a charge, the earphone itself can be discharged).
• 📱 Conflict with the firmware of the smartphone (especially on the MIUI 13+ Android 12+).
• 🔄 Unsuccessful update of headphone software (for example, after interrupted installation of the new version through Xiaomi Wear).
• 🎧 Mechanical damage to contacts in the case or antenna module (more often after falls).

A separate category is Xiaomi Earbuds clones, and fake headphones often use simplified chips that don’t support proper synchronization, if you bought the device at a suspiciously low price (below 1,500). ₽ For Redmi Buds 4, check it out for originality IMEI In the Mi Home appendix.

Warning: If the headphones have never worked together (for example, after buying separately), they may not be connected due to different versions of the firmware.

Method 1: Standard resetting and re-pairing

This is the basic method that works for all Xiaomi Earbuds models, including Redmi Airdots, Buds 3/4 and FlipBuds.The essence is to return the headphones to the factory settings and make them re-find each other.

1. Place both earphones in the case and close the lid. Wait 10 seconds.
2. Open the lid and hold the button on the case (or the touchpad on the headphones if the button is not) for 15-20 seconds until the indicator starts flashing red and white alternately.
3. On your smartphone, remove the headphones from the list of associated devices (Settings) → Bluetooth → ⚙️ → Delete).
4. Close the case, wait 5 seconds, then open it again. The headphones should automatically connect with each other (the indicator flashes white) and appear in the list of available Bluetooth devices.

Make sure both earbuds are in the case

Charge the case to at least 30%

Remove Bluetooth headphones from all devices

Prepare a smartphone for a new pairing-->

⚠️ Note: On Xiaomi Buds 3 Pro and newer models, the reset is performed differently - you need to quickly press the touch panel of each earpiece three times (not on the case!), until the sound of the beep.

If the headphones still don’t connect after reset, try connecting them to another smartphone (preferably on Android 10–11) to help eliminate a conflict with the firmware of your main device.

Method 2: Forced synchronization through the Xiaomi Wear app

For models that support proprietary software (Redmi Buds 4, Xiaomi Buds 3/4 Pro and later), you can use the Xiaomi Wear app (formerly Mi Fit), which allows you to manually initiate a search for a second headphone and update the firmware, which often solves the problem of desynchronization.

1. Install the Xiaomi Wear app from Google Play or the App Store.
2. Connect one headphone to your phone (the one that is defined). In the app, select it from the list of devices.
3. Go to Headphone Settings → Additional → Synchronization (or Connect a second headphone, depending on the model).
4. Follow the instructions on the screen. You usually need to put the second earpiece in the case, then pull it out and hold the pairing button.

⚠️ Note: If the Xiaomi Wear app does not have sync options, then your model does not support a software connection. In this case, use Method 1 (reset) or Method 3 (manual Bluetooth connection).

💡

Before syncing through Xiaomi Wear, turn off battery saving for the app in Android settings.This will prevent the connection from breaking during the process.

Method 3: Manually connect via Bluetooth menu (for power users)

This is a good method if one of the headphones is identified by the phone and the other is not, so we'll make the phone "see" both modules separately, and then pair them together.

1. Open Settings → Bluetooth on your phone and turn on search mode.
2. Take out the right earpiece (usually the lead earpiece) and wait until it appears on the list as Mi True Wireless... or Redmi Buds.
3. Connect to it. Then pull out the left earpiece -- it's supposed to automatically join the right one (you'll hear the beep).
4. If the left earpiece is not connected, return it to the case, then pull it out again and hold the touchpad for 5 seconds until the indicator blinks.

Some models (Xiaomi Buds 4 Pro) may need to manually select stereo mode in Bluetooth settings:

1. After connecting the right headphone, open its settings (icon) ⚙️ near-name).
2. Select Sound → Audio → Stereo Mode (if available).
3. Take out the left earpiece – it should connect automatically.

Method 4: Update firmware to restore communication

Outdated or damaged firmware is a common cause of desynchronization. Xiaomi regularly releases updates to fix pairing bugs to update the software:

1. Connect your headphones to your phone via Xiaomi Wear.
2. Go to the headphone settings → Update the firmware.
3. If a new version is available, click Update and wait until it is completed (don’t interrupt the process!).

For models without support OTA-Updates (e.g. Redmi Airdots 2) can be used manually via PC:

• 🖥️ Download the firmware for your model from the official Xiaomi website.
• 📁 Unpack the archive and follow the instructions in the readme.txt file.
• 🔌 Connect the case to the PC through USB-C and run the update script.

⚠️ Warning: Inept firmware can turn headphones into a brick. If you're not sure about your skills, go to a service center. BES2300 (Redmi Buds 3 Lite, where the upgrade process is different from the standard.

Method 5: Hardware inspections and repairs

If none of the software methods worked, the problem could be the hardware.

• 🔌 Contacts in the case: wipe them with alcohol and check if there is oxidation. - Xiaomi Buds 3T often leaves the right contact - it can be gently bent with a needle.
• 📶 Antenna module: if the headphones fell, the plume could be damaged.
• 🔋 Battery: If one earphone is discharged in 10 minutes, its battery needs to be replaced (especially for Redmi Airdots over 2 years old).

For the diagnosis of hardware malfunctions:

1. Try plugging each earpiece individually, and if one of them doesn't make sound, the problem is the speaker or the board.
2. Light a flashlight into the speaker's grille - if dust or moisture is visible, cleaning is required.
3. Check if the case is warming up when charging (this is a sign of a malfunction of the power controller).

If you find physical damage, but headphones are warranty, contact the service center Xiaomi.

💡

If Xiaomi Earbuds headphones do not connect after falling or getting moisture, do not try to disassemble them yourself - this can lead to a short circuit.

How to prevent repeated synchronization failures

To ensure that Xiaomi Earbuds headphones do not lose touch in the future, follow these recommendations:

• 🔄 Regularly update the firmware through Xiaomi Wear (every 2-3 months).
• 🔋 Do not allow full discharge of the case - charge it at a level below 20%.
• 📱 Use one smartphone for the main connection (frequent change of devices knocks the pairing settings).
• 🧹 Clean the contacts of the case and headphones once a month with a cotton swab soaked in isopropyl alcohol.
• 🚫 Avoid extreme temperatures (do not leave headphones in the sun or in the cold).

For models that support Dual Device Connection (Xiaomi Buds 4 Pro), disable this feature if you are not using it.

It is also useful to periodically reset the headphone settings (once every six months), even if there are no problems, this clears the pairing cache and prevents the accumulation of errors.

💡

Create a “priority connection” for Xiaomi headphones in your phone: in Bluetooth settings, select Priority Device or Auto Connection, which will reduce connection delays.
