How to combine headphones Xiaomi Earbuds: instructions for all models

Xiaomi Earbuds wireless headphones are a popular solution for music lovers and active users, but even they sometimes require manual intervention. The most common problem is that one earphone stops working, only the left/right sound is coming, or the devices do not sync at all, 90% of the time this is solved by simply resetting and re-merging, but many users do not know how to do it correctly.

In this article, we will provide step-by-step instructions for all models (from the Earbuds Basic to the Earbuds 4 Pro), including the rare cases when headphones refuse to connect. We will discuss both the standard procedure through the button and alternative methods using the Mi Home or Xiaomi Wear app, and also explain why headphones can disconnect during use and how to avoid this.

Why Xiaomi Earbuds headphones are disconnecting

Before you start to join, it is important to understand the cause of the problem, and most often, the disconnection occurs due to:

  • πŸ”‹ Battery discharge – if one headphone sits faster than the other, it can automatically disconnect from the pair.
  • πŸ“Ά Interference with Bluetooth connection – especially in places with a lot of wireless devices (metro, shopping malls).
  • πŸ”„ Firmware failure – after updating or abruptly turning off the headphones can β€œforget” each other.
  • 🎧 Mechanical damage - ingress of moisture, falls or wear of contacts in the case.

Forced reset synchronization helps in most cases, but if the problem recurs regularly, it’s worth checking the Settings β†’ Bluetooth on your phone: other connected devices (such as a smartwatch or speaker) sometimes conflict.

Standard method of combining: through a button on the case

This is a versatile method that works for all Xiaomi Earbuds models except the very first versions (such as AirDots Youth).

  1. Put both earbuds in the charge case and close the lid. Make sure the headphones don't burn (meaning they're off).
  2. Open the case cover and press the sync button (usually located on the back of the case) for 15-20 seconds until the headphone indicators start flashing red and white.
  3. Wait until the blinking turns plain white (meaning the headphones are connected) and you can plug them into your phone.

If the indicators keep flashing alternately (red-white for more than 30 seconds), then the synchronization failed.

⚠️ Warning: Don't interrupt the reset process even if it seems like nothing is happening.The Xiaomi Earbuds 3 Pro and later, the first synchronization can take up to 40 seconds due to firmware checks.

Make sure your headphones are charged (minimum 30%)

Remove the headphones from the ears and put them in the case

Close the case cover for 5 seconds before resetting

Press the synchronization button strictly for 20 seconds (at least)

Connecting with Mi Home/Xiaomi Wear

If the button on the case does not work or the headphones do not respond, you can try syncing them through the official application. This method is suitable for Earbuds models 3/4 series and later, where there is support for firmware updates.

Instructions:

  1. Install the Xiaomi Wear app (for new models) or Mi Home (for older models).
  2. Open the app and go to Devices β†’ Add Device β†’ Headphones.
  3. Choose your Earbuds model from the list. Headphones should be in a case with an open lid.
  4. Follow the hints on the screen. If the app offers to update the firmware, agree (this often solves synchronization problems).

In some cases, the app may show a "failed to connect" error, which means that the headphones are not recognized as a pair.

  • πŸ”„ Try restarting your phone and trying again.
  • πŸ“± Remove headphones from the list of conjugated devices in Bluetooth settings.
  • πŸ”‹ Check that the case is charged (the indicator on the case should burn green when connected to the charger).
What to do if the app does not see the headphones?
If the Mi Home or Xiaomi Wear doesn’t detect the headphones: 1. Make sure the phone is enabled with Bluetooth and geolocation (the app needs permissions). 2. Try connecting from another device (tablet or second phone). 3. Check if the connection is blocked by antivirus or power saving mode. 4. Earbuds 4 Pro may require an update to the latest version (the Play Market sometimes hangs an outdated build).

Solving Sound Problems After Combination

Even if the headphones are successfully synchronized, other problems may arise:

Problem.Possible causeDecision
The sound is only in one headphone.Failure to distribute audio streamIn Bluetooth settings on your phone, select Cog Settings β†’ Audio β†’ Mono / Stereo β†’ Stereo
The headphones are connected, but quickly disconnectedWeak Bluetooth signal or interferenceRestart your phone and headphones, try elsewhere
The microphone is not working.Incorrect connection as a "playback device"In Bluetooth settings, turn off your headphones and reconnect by selecting Use for calls.
Crackling or intermittent soundOutdated firmware or codecUpdate your firmware through Xiaomi Wear or change the codec to SBC in the developer settings

If after combining in the headphones you can hear an echo or a delay of sound, try:

  • 🎡 Turn off the sound effects in your phone settings (such as Dolby Atmos or Equalizer).
  • πŸ“± Switch the Bluetooth codec to AAC (developer-setting).
  • πŸ”„ Remove the headphones from the case and insert back (sometimes β€œreboot” the connection helps).

πŸ’‘

If Xiaomi Earbuds 4 Pro headphones give an error "Device is not supported" when connecting to an iPhone, try connecting them to an Android smartphone first and updating the firmware. After that, they should work normally with iOS.

What to do if the headphones do not combine at all

If none of these things worked, it might be a hardware problem.

  1. Contacts in the case β€” gently wipe them with a cotton swab with alcohol. Oxidation or dirt can interfere with charging and synchronization.
  2. Case firmware – some models (e.g. Earbuds 3T) require not only an update to the headphones, but also the case itself.
  3. Phone Compatibility – Older smartphones (like those on Android 8 and below) may not support the new LC3 codec used in the Earbuds 4 Pro.

If the headphones are not synchronized:

⚠️ Warning: Don't try to disassemble the headphones yourself - this will lead to loss of warranty. Xiaomi service centers have special equipment for flashing and diagnosing wireless headphones.

For the Earbuds Basic and Earbuds S models, there is another way to force reset:

1. Get both earphones out of the case.


2. Press the touch panels on both headphones for 10 seconds until the lights go out.




3. Put the headphones back in the case and close the lid for 30 seconds.




4. Open the lid - the headphones should automatically sync.

How to avoid splitting headphones in the future

To avoid the problem recurring, follow simple rules:

  • πŸ”‹ Charge your headphones regularly – don’t let the discharge be below 10.
  • πŸ“¦ Keep your headphones in a case – this not only protects them, but also supports the connection between them.
  • πŸ“² Update your firmware through Xiaomi Wear at least once every 2-3 months.
  • 🚫 Don’t connect your headphones to multiple devices at the same time – this can knock your sync settings down.

If you use headphones frequently for sports or outdoors, you should turn off Absolute Volume (on Android) in your Bluetooth settings, which can cause conflicts when adjusting the sound.

The most common reason Xiaomi Earbuds disconnect is not a firmware failure, but a banal discharge of one of the headphones. Always check the charge before using!

FAQ: Frequent questions about Xiaomi Earbuds

Can I combine headphones from different cases (for example, if I lost one)?
No, it's impossible. Each earpiece is tied to its own case at the firmware level, and even if the models are identical, they don't sync with each other, so you have to buy a new set.
Why do headphones connect to the phone as two separate devices?
This happens if the reset was incorrectly done: Remove both headphones from the list of Bluetooth devices, reset through the button on the case (press for 20 seconds), reconnect the headphones – they should appear as a single device (for example, Xiaomi Earbuds 4 Pro).
How do you check if the headphones are really together?
There are three signs of successful synchronization: The indicators on both headphones flash white at the same time; Bluetooth settings display one device (not two separate ones); when playing the sound, it goes to both earphones without delay.
What if after updating the firmware headphones stopped to merge?
This is a rare but possible problem. Try: roll back the firmware through Xiaomi Wear (if the previous version is available); make a full headphone reset (press the button on the case for 30 seconds); Call for Xiaomi support - sometimes "raw" updates come out, which thelater patches.
Can I use one headphone separately if the other is broken?
Yes, but with reservations: 🎧 In mono mode, only the left or right headphone will work (depending on the model). πŸ”Š The sound quality may deteriorate (for example, the bass range will be lost). πŸ“ž For calls, you'd better use a right earphone, which is usually better than a microphone. To activate mono mode, take one earphone out of the case and wait 5-10 seconds until it connects to the phone.
