What to do if the headphones Xiaomi Mi True Wireless do not mate with each other

Did you pull out of a Xiaomi Mi True Wireless case and one headphone doesn't connect to the other? Or do both devices flash white/red but don't sync? This problem is familiar to many owners TWS-Xiaomi headphones, especially after long downtime, firmware updates or mechanical damage, 80% of the time, the malfunction is solved software-based, without going to the service center.

In this article, we will look at all possible causes, from a simple battery discharge to a firmware failure, and give step-by-step instructions with photos and videos on how to return the headphones to work. Special attention will be paid to the models of Mi True Wireless Earphones 2, Mi AirDots and Redmi AirDots, because their pairing algorithms are different. If you have tried to reset, but nothing has worked, do not rush to throw out the headphones: at the end of the article there is a section with hidden methods that are not even written in the official documentation.

Why Xiaomi Headphones Don’t Mix: 5 Main Reasons

Before you start repairing, it is important to understand what went wrong, and here are the most common reasons for Mi True Wireless not being synchronized:

• 🔋 A discharged battery - one of the headphones is discharged to 0% and can not turn on for pairing.
• 🔄 Firmware failure – after updating the software through Mi Home or Xiaomi Wear, a version conflict could occur.
• 📱 Phone conflict – headphones “hang” in the memory of the smartphone as separate devices (for example, after connecting to another gadget).
• 🛠️ Mechanical damage – ingress of moisture, falling or wearing of contacts in the case disrupt synchronization.
• 🔌 Case problems – if charging contacts are contaminated or damaged, headphones can’t “share” data for a couple.

Interesting fact: Xiaomi Mi True Wireless Earphones 2 Basic uses a separate synchronization chip (BES2300) that can freeze when the power is cut abruptly. In newer models (for example, Redmi Buds 4 Pro), this problem is solved at the firmware level.

Method 1: Complete resetting of headphones to factory settings

This is the first thing to do if the headphones don't sync. The reset procedure differs depending on the model, but the general principle is the same: return to a "clean" state, as after buying.

Xiaomi Mi True Wireless Earphones 2 and Redmi AirDots

1. Put both headphones in the case and close the lid.
2. Wait until the indicator on the case does not go out (this means that the headphones are charged).
3. Press and hold the button on the case (usually located behind) for 15-20 seconds until the indicator flashes red and white.
4. Open the lid – the headphones should automatically go into pairing mode (blinking white light).

For Mi AirDots Pro and Redmi Buds 3/4:

1. Get the headphones out of the case.
2. Press the touch panels on both headphones simultaneously for 10 seconds until you hear the beep.
3. Put the headphones back in the case and try again to connect.

Make sure the cover is at least 30 times charged%|

Check that the headphones are clean (no dirt on the contacts)|

Turn off headphones from all devices in Bluetooth | settings

Use the original cable to charge the case-->

Important! After reset, Xiaomi headphones may not appear in the list of Bluetooth devices until you take them out of the case and wait for the flashing white indicator. If the indicator is on red, then the reset did not pass, repeat the procedure.

Method 2: Manual synchronization through forced pairing

If the reset didn't work, try to force the headphones to be paired manually, a method that works when one of the headphones (usually the right one) is defined as a separate device and the other isn't.

Instructions:

1. Get both earphones out of the case.
2. On your smartphone, turn on Bluetooth and remove all previously saved devices called Mi True Wireless, Redmi AirDots, etc.
3. Press the touchpad on the right earphone for 5 seconds until you hear the voice message “Conjugation” (or see a flashing white light).
4. Repeat the same for the left earpiece.
5. Wait 30–60 seconds – the headphones should automatically connect with each other (the indicators will start flashing synchronously).
6. Now connect to them from your smartphone as a new device.

If after these actions, the headphones still do not sync, check:

• 🔋 Charge level of the cover (must be at least 20%).
• 📶 Distance between headphones (not further than 10 cm from each other).
• 🛡️ No interference from other Bluetooth devices (Wi-Fi routers, microwaves).

💡

If the headphones squeak but don't connect, try putting them in a case for 10 minutes and then repeat the procedure. Sometimes it helps to "reboot" the Bluetooth controller.

Method 3: Checking and cleaning the contacts of the cover

One of the most underappreciated causes of malfunction is contaminated or oxidized contacts in the case. Xiaomi Mi True Wireless headphones are synchronized not through the air, but through metal contacts at the bottom of the case, if they are covered with dust or corrosion, the signal does not pass.

How to clean contacts:

1. Take the headphones out of the case and inspect the gold/copper dots on the bottom of the case and on the headphones themselves.
2. Take a cotton swab soaked in isopropyl alcohol (or regular vodka) and gently wipe the contacts.
3. To remove oxidation, you can use an eraser (carefully, without pressing!).
4. Allow the contacts to dry for 5-10 minutes.
5. Put the headphones in the case and wait until the indicator lights up green (meaning charging and data exchange).

Critical error: if after cleaning the contacts, the indicator on the case still does not burn, and the headphones do not charge, this is a sign of a malfunction of the power controller, in which case repair will be required at the service center.

Method 4: Update the firmware through Mi Home or Xiaomi Wear

Firmware failures are a common reason why Xiaomi Mi True Wireless stops conjugating. The manufacturer regularly releases updates that fix synchronization bugs. OTA-updates (over air).

How to update firmware:

1. Install the Xiaomi Wear app (for new models) or Mi Home (for older models).
2. Connect the headphones to your smartphone (if they are defined as separate devices, reset first).
3. Open the app, find your headphones in the list of devices.
4. Go to Settings → Update firmware.
5. If a new version is available, click Update and wait until it is completed (don’t turn off Bluetooth!).

⚠️ Attention! Do not interrupt the upgrade process - this can lead to a complete loss of performance of the headphones. If the firmware "hangs" during the boot phase, put the headphones in the case, close the lid and wait 10 minutes, then try again.

Method 5: Checking for hardware damage

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

• 🔊 One of the headphones does not make sounds (even after resetting).
• 🔋 The headphone does not charge in the case, although the contacts are clean.
• 💧 On the body or inside the connector, traces of corrosion / oxidation are visible.
• 🔌 The indicator on the case does not respond to the press of the reset button.

The most vulnerable elements in Xiaomi Mi True Wireless:

1. Charging contacts – over time, oxidize or move away from the board.
2. Battery - swells and presses on the board, breaking the connection.
3. Bluetooth module – fails when overheating or falling.
4. Microphone – clogged with dust, because of which the headphone can not “respond” to commands.

⚠️ If you notice one of the headphones getting hot when charging or using, stop using immediately! This is a sign of a faulty battery that could ignite.

Method 6: Alternative methods (if nothing helps)

If the standard methods didn’t work, try the non-obvious solutions that sometimes save even the “dead” headphones:

• 🔄 «Flashing through another smartphone: connect the headphones to another phone (preferably on Android 10)+), Do the reset and try to update the firmware.
• ❄️ Freeze: Put the headphones in the case in the freezer for 1-2 hours (sometimes this “resuscitates” the oxidized contacts.
• 🔌 PC Connection: Some models (e.g. Redmi AirDots 2) can be reset via your computer's Bluetooth adapter (use Bluetooth Command Line Tools utility).
• 🔋 Artificial discharge: discharge the case to 0%, then charge to 100% - sometimes this resets controller errors.

💡

If Xiaomi Mi True Wireless headphones are still out of sync after all the manipulations, but each of them works separately (connects to the phone), the problem is most likely in the master chip (usually in the right earphone), in this case, only replacing the board in the service will help.
