How to sync Xiaomi Mi True Wireless Earphones 2 headphones with each other: the complete guide

Xiaomi Mi True Wireless Earphones 2 is a popular model with high-quality sound and convenient ergonomics. However, many users face the problem of mismatched left and right earphones: one of them may not connect, lag behind in sound or not sync with the other, most often after resetting, updating the firmware or prolonged inactivity of the device.

In this article, you will find detailed instructions on how to synchronize headphones with each other, as well as solving typical problems — from basic checks to hidden functions that are not written about in the official documentation.

We'll focus on the reasons for desynchronization: why it happens and how to prevent the problem from happening again. If you've tried rebooting your headphones but nothing has worked, don't rush to bring them to the service: 90% of the time, you can solve the problem yourself in 5-10 minutes.

Why are Mi True Wireless Earphones 2 Headphones Not Synced?

Before you start setting up, it is important to understand the root of the problem.Mi True Wireless Earphones 2 headphones can lose communication with each other for several reasons:

• 🔋 A discharged battery of one of the headphones or case (even if the indicator is on, the voltage may not be enough to synchronize).
• 📱 Failure of firmware after updating or incorrect disconnection (for example, if you remove the headphones from the case during data transfer).
• 🔄 Manual resetting of settings on one of the headphones (for example, if you accidentally pinched a button on the case).
• 🎧 Connecting to different devices: if the left earbud was paired with the phone, and the right with the laptop, they “forget” each other.
• 🛠️ Mechanical damage to contacts in the case or the headphones themselves (oxidation, pollution).

The most common situation is when one earphone connects to the phone and the other is silent, which means that the connection between the headphones is lost, but the connection to the sound source (smartphone, PC) is preserved. Less often, the reverse problem occurs: both earphones are connected to the phone, but the sound is only in one (usually the right one).

Before you start taking action, check:

• ✅ Whether both earphones are charged (indicators on the case should burn white, not red).
• ✅ Are there physical obstacles between headphones (walls, metal objects).
• ✅ Are the headphones connected to the same device (sometimes they can automatically reconnect to the last used gadget).

Method 1: Synchronization via a button on the case (basic method)

The easiest and most official way to get back in touch between the headphones is to use a button on the back of the case, which works 80 percent of the time and doesn't require any additional devices.

1. Place both headphones in the case and close the lid.
2. Wait 10 seconds – during this time, the headphones should be determined by the case as connected.
3. Open the case cover and hold the button on the back for 15-20 seconds until the indicator starts flashing red and white alternately.
4. Release the button. The indicator should light up white, which means that the headphones are synchronized.
5. Get the headphones out of the case – they should automatically connect to each other and to the last device used.

If the headphones are still not working together after these actions, try repeating the procedure, but in step 3 hold the button for up to 30 seconds - this will lead to a complete reset.

⚠️ Warning: If your headphones stop connecting to your phone after reset, remove them from the list of associated devices in your Bluetooth settings and reconnect. Sometimes old data conflicts with new settings.

Method 2: Sync with Mi Home or Xiaomi Wear

If the button on the case did not help, try syncing the headphones through the official application. For Mi True Wireless Earphones 2, two options are suitable:

• 📱 Mi Home – universal application for all Xiaomi devices (available for Android and iOS).
• 🎧 Xiaomi Wear – a specialty app for wearables (recommended for more accurate customization).

Instructions for Xiaomi Wear (on the example of Android):

1. Install the app from Google Play or the App Store.
2. Open the app and allow access to location and Bluetooth.
3. Place the headphones in the case, open the lid and press Add Device → Headphones → Mi True Wireless Earphones 2.
4. Follow the instructions on the screen. The app will automatically check the connection between the headphones and prompt you to update the firmware if necessary.
5. After you connect, go to Headphone Settings → Reset and confirm the action. The headphones will reset and sync.

Mi Home has a similar process, but the interface may be different.

• 🔄 Reboot Bluetooth on your phone (Settings) → Bluetooth → Turn off/Enable).
• 📱 Make sure your phone has location enabled (required to search for Bluetooth Low Energy devices).
• 🔋 Check the headphones’ charge – if the level is below 20%, the app may not recognize them.

Method 3: Hard resetting of headphones (if nothing helps)

If standard methods don't work, you'll have to reset the setup completely to the factory, which will remove all the connections you've saved and bring the headphones back to their original state.

Hard-dumping instructions:

1. Place both headphones in the case and close the lid.
2. Open the lid and hold the button on the case for 40-50 seconds until the indicator flashes red (this is a reset signal).
3. Release the button. The indicator goes out, then lights up in white, the reset is complete.
4. Take the headphones out of the case. They should automatically sync and go into pairing mode (blinking white light).
5. Connect them to your phone as a new device.

If the headphones are still out of sync after reset, the problem may be a hardware malfunction.

• 🔌 Contacts in the case and on headphones for oxidation or contamination (clean with an alcohol napkin).
• 🔊 Does the microphone work in each earphone (try recording a voice message).
• 📦 Was there any mechanical shock or moisture (even if the headphones are waterproof, condensate can disrupt the work).

⚠️ Warning: After a hard reset, the headphones may require a firmware update. If a notification of an update appears in the Xiaomi Wear app, do not ignore it, as outdated firmware often causes desynchronization.

How to prevent re-synchronization?

To ensure that Mi True Wireless Earphones 2 headphones do not lose touch in the future, follow these recommendations:

• 🔋 Charge your case regularly – even if the headphones are not used, connect the case to charge for 10-15 minutes every 2-3 weeks.
• 📱 Don't connect your headphones to multiple devices at once. If you want to switch from phone to laptop, first disconnect them from the first device.
• 🔄 Update your firmware through Xiaomi Wear when notifications appear.New versions often fix sync bugs.
• 🧹 Clean contacts once a month with a cotton swab dipped in isopropyl alcohol. Contact oxidation is one of the main causes of hardware failures.
• 🛡️ Avoid extreme temperatures. Don't leave your headphones in the sun or in the cold - this can damage your battery and electronics.

Critical information: If you use headphones with iOS devices, periodically check your Bluetooth settings. iPhone system sometimes “forgets” the profile of the headphones, which leads to a break in the connection between the left and right module, in which case it will help to remove the device from the Bluetooth list and reconnect.

💡

If your headphones often disconnect during a conversation, turn off the Auto Sound Switch feature in your smartphone’s Bluetooth settings. This option may conflict with Xiaomi’s sync protocol.

Frequent Mistakes and How to Avoid Them

Many users make common mistakes when trying to sync their headphones, which only makes the problem worse.

• ❌ Pressing the button on the case too short (less than 15 seconds) will result in a simple shutdown, not a reset.
• ❌ Use non-original chargers. Unstable voltage can damage Bluetooth controller.
• ❌ Try to sync the headphones separately (for example, connect one first, then the other) They should always work in pairs.
• ❌ Ignore firmware updates. Outdated software causes 30% of synchronization problems.

Another common mistake is to use headphones at the highest volume, which not only harms your hearing, but can also cause Bluetooth overload, leading to communication disruption, and the optimal volume level is 70-80% or less.

If you connect your headphones to a PC or Mac, make sure you have the latest Bluetooth drivers installed. On Windows, you can check this through Device Manager → Bluetooth. On a Mac, upgrade macOS to the latest version.

💡

Before selling or transferring the headphones to another person, make sure to reset.This will delete your data and prevent connection problems from the new owner.
