How to synchronize headphones Xiaomi True Wireless with each other: instructions and tips

Xiaomi True Wireless is a popular solution for music lovers and active users, but sometimes they stop syncing with each other. One headphone can be silent, disconnected or play back with a delay, and the second one can work normally. The causes of this problem lie in the failure of pairing between the right and left modules, battery discharge or software errors. In this article, we will discuss how to return synchronization to Mi True Wireless, Redmi AirDots and other models of the brand – from simple ways to complete resetting.

It's important to understand that synchronization is different from connecting your headphones to your smartphone, and it's about connecting the headphones themselves (right and left), which ensures stereo and stable performance. If you're faced with one headphone not making a sound or flashing like the other, this will help restore their interaction, and we'll also look at common user errors and give you tips on how to avoid problems in the future.

Why Xiaomi True Wireless Headphones Lose Sync

Before you start setting up, you should understand the causes of the problem, most often synchronization is lost due to:

• 🔋 Battery discharge – if one earphone is discharged stronger than another, it can automatically disconnect from the pair.
• 📱 Incorrect connection to the device – for example, if you manually selected Bluetooth only one headphone.
• 🔄 Software failure - after updating the firmware or abrupt power outage.
• 🎧 Mechanical damage – ingress of moisture, impacts or wear of contacts in the case.
• 📦 Resetting settings – after returning to factory parameters, headphones “forget” each other.

In most cases, the problem is solved by rebooting or forced synchronization. However, if the headphones are physically damaged (for example, after a fall), one of the modules may need repair or replacement. Note: if both earphones are not turned on or detected by the device, the problem is most likely in the case or battery - this is a separate topic for diagnosis.

Preparing for synchronization: what to do in advance

Before you start setting up, follow a few simple steps to avoid typical errors:

1. Charge your headphones and case – make sure the lights on the case are green or white (depending on the model). If the battery is discharged below 20%, sync may not start.
2. Remove the headphones from the case and wait until they automatically turn on (the indicator blinks).
3. Remove the headphones from the list of Bluetooth devices on your smartphone or PC, which will help avoid conflicts when reconnecting.
4. Check the physical condition – there is no visible damage, moisture or dirt on the contacts.

If the headphones don’t turn on after being removed from the case, try forcefully rebooting them: press the touchpad (or mechanical button) on both headphones for 10-15 seconds until the indicators go out and flash again.

Make sure the cover is charged (green/white indicator)

Method 1: Automatic synchronization (for most models)

In most cases, Xiaomi True Wireless headphones sync automatically when properly removed from the case.

1. Put both headphones in the case and close the lid.
2. Connect the case to charge for 5-10 minutes (even if it is charged).
3. Take out both headphones at the same time and wait 10-15 seconds.
4. The headphones should flash synchronously (usually in white or blue).
5. Connect to headphones via Bluetooth on your smartphone – they should be defined as one device (for example, Mi True Wireless Earbuds Basic 2).

If the lights are flashing separately or one of the headphones is not showing signs of life, then proceed to the following method.

💡

If the headphones don't sync after the automatic method, try putting them back in the case, closing the lid for 30 seconds, then re-extracting them. Sometimes this helps to reset temporary connection errors.

Method 2: Forced synchronization through the reset button

If the automatic method didn’t work, try force-syncing your headphones manually, a method that works for most models, including the Redmi AirDots, Mi True Wireless Earbuds 2 and Xiaomi Buds 3.

1. Get both earphones out of the case.
2. Press and hold the touchpad (or button) on both headphones simultaneously for 10-15 seconds.
3. The indicators will first go out, and then start flashing red and white (or red and blue - depending on the model).
4. Release buttons – the headphones should automatically sync (the indicators will start flashing synchronously).
5. Connect to them via Bluetooth on your smartphone.

If after these actions one of the headphones still does not work, check:

• 🔌 Headphone charge – perhaps one of them is discharged more strongly and can not establish a connection.
• 📶 Distance to smartphone – sometimes headphones lose communication if the device is too far away (more than 10 meters).
• 🔄 Bluetooth Settings – Make sure your smartphone doesn’t activate the power saving mode that may limit the connection.

Method 3: Completely reset (if nothing helps)

If previous methods fail, reset the headphones completely, and it will bring them back to factory settings and make them sync again. Attention: once reset, the headphones will be removed from the memory of all connected devices, and they will have to be paired again.

Instructions for most Xiaomi True Wireless models:

1. Put both headphones in the case and close the lid.
2. Open the cover and hold the button on the case (if any) for 10-15 seconds. For models without a button on the case, use the touch panels on the headphones themselves (hold on both at the same time).
3. The indicators on the headphones will start flashing red and white - this is a signal of a reset.
4. Get the headphones out of the case – they should automatically synchronize (the indicators will flash synchronously).
5. Connect to them via Bluetooth as a new device.

For some models (such as Xiaomi Buds 4 or Redmi AirDots 3 Pro), the reset process may be different. If your headphones have their own app (such as Mi Earphones or Xiaomi Wear), try resetting through it:

1. Open the app and find the headphone settings section.
2. Select Reset to factory or Forget the device.
3. Confirm the action and wait for the process to be completed.
4. Remove the headphones from the case and connect again.

💡

Complete reset is a last resort, only use it if other methods have not helped, as after resetting the headphones will lose all saved settings (for example, customization of gestures or equalizer).

Frequent Mistakes and How to Avoid Them

Many users make the same mistakes when syncing Xiaomi headphones, which leads to repeated crashes.

• 📵 Connect only one headphone manually via Bluetooth. Always choose the full name of the headphones from the list of devices (for example, Mi True Wireless Earbuds Basic). 2, not LE_Mi True Wireless).
• 🔋 Ignoring low charge. If the battery is under 30%, the headphones may not sync. Always charge them before setting up.
• 📱 Use outdated firmware. Check for updates in the Mi Earphones or Xiaomi Wear app.
• 🔄 Interrupt the synchronization process. Do not put the headphones back in the case until they have completed pairing (indicators should flash synchronously).

Another common problem is device incompatibility, such as some Xiaomi True Wireless models that may not work properly with iPhones or older versions of Android, in which case you might try connecting your headphones to another smartphone or tablet to check if they work.

⚠️ Warning: If one of the headphones is still out of order after all the manipulations, check for physical damage. Often the problem lies in oxidized contacts (the earphone does not charge in the case) or damaged speakers (the sound is missing, but the indicator is on). In this case, repairs may be required.

Additional Tips for Stable Work

To avoid synchronization problems in the future, follow these guidelines:

• 🔄 Update your firmware regularly through the official Xiaomi Wear or Mi Earphones app. Updates often fix connection errors.
• 📦 Keep your headphones in your case when you’re not using them, and this prevents battery drain and accidental connections to other devices.
• 🔋 Keep the case charged when the indicator shows less than 20% charge.
• 🎵 Use uniform volume. Sharp volume surges can cause Bluetooth modules to malfunction.

If you often experience sync problems, try changing the Bluetooth codec in your smartphone settings. For example, on Android, go to Settings → Bluetooth → Headphone settings → Audio codec and choose AAC or SBC over aptX. This can improve connection stability, especially on budget headphone models.

💡

For models that support Xiaomi HyperSync (such as Xiaomi Buds 4 Pro), enable this feature in the app.It reduces sound delays and improves synchronization between headphones.

What to do if nothing helps

If all methods have been tried, but the headphones still don’t sync, perhaps the problem lies in:

• 🛠️ Hardware malfunction – damaged Bluetooth module in one of the headphones.
• 🔌 Faulty cover - it does not charge one of the headphones, because of which it does not turn on.
• 📲 Software conflict – for example, if the headphones were previously connected to another device with an outdated version of Bluetooth.

In these cases:

1. Contact the Xiaomi service center (if the headphones are guaranteed).
2. Try connecting your headphones to another device (like a PC or tablet) to rule out a smartphone problem.
3. Check the contacts in the case for dirt or oxidation. Clean them with a cotton swab soaked in alcohol.

⚠️ Warning: Do not disassemble the headphones yourself, this will lead to loss of warranty. If you are not sure about the cause of the malfunction, you should consult a specialist.
