How to synchronize Xiaomi Redmi headphones with each other: from basic settings to problem solving

Xiaomi Redmi wireless headphones are among the most popular accessories due to the combination of price, sound quality and functionality. However, many users face difficulties when first syncing headphones with each other or after resetting. Unlike wired models, where it is enough to simply insert a plug, wireless TWS-Headphones require the right sequence of actions for stable pairwork.

In this article, we’ll not only look at the standard process of connecting Redmi AirDots, Redmi Buds or Redmi Earbuds headphones to each other, but also look at common errors that interfere with synchronization. You’ll learn how to check the model’s compatibility with your smartphone, what to do if one headphone doesn’t connect, and how to update the firmware to improve communication stability.

If you just bought headphones or faced a problem after upgrading your phone, this guide will help you get them back to normal without going to the service center.

1. Preparation of Xiaomi Redmi headphones for synchronization

Before you start connecting the headphones, make sure they are ready for the process. Many problems arise from basic omissions: a discharged battery, mechanical damage or incompatibility with the device.

Here are the prerequisites for successful synchronization:

  • πŸ”‹ Headphones charge level – at least 30% (at low charge, they may not turn on or off during the process).
  • πŸ“± Compatible device: smartphone on Android 6.0+ iOS 10+ Bluetooth 4.2 or later.
  • πŸ”„ Headphones are not connected to other devices (such as a laptop or tablet) – this can block synchronization.
  • πŸ› οΈ No physical damage: make sure that the charging case contacts are free of oxidation or dirt.

If you've got your headphones out of the case, but they don't respond to the press, try a forced restart: put them back in the case, close the lid for 10 seconds, then remove them. This will reset the current state and prepare them for the new synchronization.

⚠️ Note: If Xiaomi Redmi Buds 3 Lite or Redmi AirDots 3 headphones have previously connected to another smartphone, they may automatically try to connect to it. To avoid this, remove them from the list of conjugated devices on the old phone or reset (instructions in the next section).

2. Standard procedure for synchronizing headphones with each other

In most cases, Xiaomi Redmi headphones sync automatically when you first remove them from the case, but if you don’t, follow the manual instructions:

  1. Remove both headphones from the case and wait until they start flashing white/red lights (Device Search Indicator).
  2. Press the touchpad on both headphones simultaneously for 5-7 seconds until you hear the beep (or see a flashing red-blue in models with a flashing headphone). RGB-indicator).
  3. Place the headphones back in the case, close the lid and wait 10 seconds - they should sync inside the case.
  4. Get the headphones out again – they now have to work as a stereo (left and right channels).

For Redmi Buds 3 Pro and later, the process is simplified: just remove the headphones from the case, they automatically connect to each other and go to search mode to connect to the phone. If this does not happen, check whether the smartphone activates the "Energy Saving" mode, which can block Bluetooth connections.

Done: 0 / 5

If after these actions, the headphones are still not synchronized, move to the next section - you may need to reset the settings.

3.Reset Xiaomi Redmi headphone settings for re-synchronization

Reset (or hard reset) returns the headphones to factory settings and often solves connection problems.

Model headphonesReset combinationSign of successful discharge
Redmi AirDots (1/2 gen)Hold both touch panels for 15 seconds (in or out of the case)Double flashing in red, then white
Redmi Buds 3 / 3 LitePress the left earphone touch panel three times for 2 secondsSound signal + purple flashing
Redmi Earbuds SPress the touch panel of the right earphone for 10 seconds (in the case)Voice Alert "Reset Successful"
Redmi Buds 3 ProPress and hold both panels for 10 seconds before the beepFlashes orange, then white

Once reset, the headphones automatically erase information about previous connections and return to the "out of the box" state, and can now be synchronized again using the instructions in the second section.

⚠️ Note: Redmi AirDots 2 and older models may require a firmware update via the Mi Home or Xiaomi Earbuds app after a reset.

What to do if the reset does not work?
If the headphones don’t respond to the standard combination, try: 1. Put them in a case and connect the case to charge for 30 minutes (sometimes a discharged battery blocks the reset). 2. Use another charger – some models require a current of at least 1A to activate service functions. 3. Check the contacts in the case for contamination (wipe with alcohol). If nothing helps, the control board may be damaged (repair is required).

4. Solving typical synchronization problems

Even after a reset, Xiaomi Redmi headphones can behave incorrectly. Let’s consider the most common scenarios and ways to eliminate them:

Problem 1: One earphone is not connected

If the left or right earphone is not synchronized:

  • πŸ”‹ Check the battery power - the often silent earphone is just dead. Place both in the case for 15 minutes.
  • πŸ”„ Reset only for a problem earphone (for most models, pinch its touchpad for 10 seconds).
  • πŸ“² Remove the headphones from the list of Bluetooth devices on your phone and connect again.
  • πŸ› οΈ Check the physical condition: sometimes the plume of the speaker (crackling when pressing the body) leaves).

Problem 2: Headphones are connected separately, but not together

This is typical of Redmi Buds 3 Lite models after a firmware update.

  1. Remove both headphones from the phone’s Bluetooth settings.
  2. Put them in the case, close the lid.
  3. Remove only the main headphone (usually the right one) and connect it to the phone.
  4. Get the second headphone – it should automatically connect to the first.

Issue 3: Persistent communication breakdowns

If the headphones are synchronized, but the sound is interrupted:

  • πŸ“Ά Check the distance to the phone – the maximum stable distance for Xiaomi Redmi is 10 meters without obstacles.
  • πŸ”„ Reboot the phone’s Bluetooth module (turn it off/on in settings).
  • πŸ“± Update the headphone firmware through Mi Home (instructions in the next section).
  • 🎧 Check the sound settings: turn off "Absolute Volume" in Settings β†’ Bluetooth β†’ Headphone settings.

πŸ’‘

If Redmi AirDots 3 headphones start to "glutch" after connecting to a PC, reset and connect them first to a smartphone. Some models conflict with Windows Bluetooth stacks.

5. Update firmware for stable synchronization

The manufacturer regularly releases firmware updates for Xiaomi Redmi headphones, which fix synchronization errors, improve sound and add new features.

  1. Install the official app: For Android: Mi Home or Xiaomi Earbuds (from Google Play). For iOS: Mi Home (from the App Store).

Bluetooth

Open the app, find your model in the list of devices.

"Firmware update"

"Firmware Update"

"Update"

For Redmi Buds 3 Pro and later, the update can take up to 5 minutes.

  • πŸ”‹ The case must be connected to the charge (case battery level is at least 50%).
  • πŸ“Ά The phone must be connected to Wi-Fi (update downloaded via the Internet).
  • 🚫 Do not use headphones during the upgrade – this may cause a crash.

After the update, the headphones will automatically restart. If the sync is not restored, reset and reconnect.

πŸ’‘

Updating the firmware through Mi Home is the only official way to fix software synchronization errors. Handheld firmware from the Internet can turn headphones into a brick.

Checking after synchronization

After successfully connecting headphones, check their work on the following checklist:

  1. Stereo sound: Play a track with clear channel separation (e.g., a test file with left and right sound) and both earphones must play their own channel.
  2. Microphone: Record a voice message – sound should be transmitted without noise (for models with ENC-noise reduction, check in a noisy room).
  3. Gesture control: Single touch - playback / pause. Double touch - next track (on Redmi Buds 3 Pro - voice assistant call). Retention - turn off noise reduction (if supported).

Automatic shutdown:

If any of these items fail, go back to the problem-solving section or reset again. For models with ANC (active noise reduction), check the settings in the Mi Home app β€” sometimes the feature is disabled by default.

7. Alternative synchronization methods (for experienced users)

If standard methods do not help, you can try non-obvious techniques that are rarely mentioned in official instructions:

Method 1: Forced synchronization through the case

For Redmi AirDots 2 and Redmi Buds 3 Lite:

  1. Place both headphones in the case and close the lid.
  2. Connect the case to the charger.
  3. Press and hold the button on the case (if any) for 10 seconds.
  4. Open the lid – the headphones should sync automatically.

Method 2: Using the second phone

Sometimes the headphones forget the main device and refuse to sync.

  1. Connect the headphones to another smartphone (or tablet).
  2. Wait for the synchronization to work (both channels must work).
  3. Remove them from the list of devices on the second phone.
  4. Go back to the main phone and connect again.

Method 3: Activate the service menu (Redmi Buds 3 Pro only)

On some firmware, a hidden menu for diagnosis is available:

  1. Put the headphones on the phone.
  2. Open the Mi Home app and go to the headphone settings.
  3. Click 5 times on the firmware version and the service menu will open.
  4. Select "Reset Pairing Data" (reset pairing data).

If the headphones connect to the PC only in "Headset" mode, remove them from the list of devices and connect again by selecting the "Stereo" option.

Why did the headphones stop syncing after the firmware update?
This is a typical problem for Redmi Buds 3 Lite models when upgrading to 1.4.0.6+. Solutions: Reset your headphones (see section 3). Roll back the firmware via Mi Home if the previous version is available (not always possible). Connect your headphones to another device (like a tablet), then return to your phone. If the problem persists, contact Xiaomi support - it may be necessary to change the firmware at the service center.
How do you determine which headphone is the main (master) and which is the auxiliary (slave)?
In most Xiaomi Redmi models, the right earbud is the master, which connects directly to the phone, and the left earbud connects to it. The left earbud is the slave, which cannot work separately from the right one. Except: Redmi AirDots 3 Pro supports independent connection of each earbud (Mono mode).
What if the headphones are synchronized, but the sound is only in one?
Causes and solutions: πŸ”Š Incorrect phone settings: check the sound balance in Settings β†’ Sound. β†’ Stereo balance (should be) 50/50). πŸ”‹ One headphone discharge: place both in the case on 15 minute. πŸ”„ Synchronization failure: perform reset and connect again. πŸ› οΈ Hardware malfunction: if the problem persists - a wire break in the dynamics is possible (repair is required).
Can I use Xiaomi Redmi headphones with an iPhone?
Yes, but with limitations: βœ… Supported basic functions: sound reproduction, call reception. ❌ Not working: Gesture control (on some models); display battery level; firmware update (requires Android device). πŸ“± For connection: Settings β†’ Bluetooth β†’ Select headphones. On iOS 14+ possible problems with automatic synchronization after extraction from the case - in this case, manual connection will help.
