Mi True Wireless Earphones Aren't Synced? Solve the Problem in 5 Steps

Xiaomi Mi True Wireless Earphones have become one of the most popular accessories due to the combination of sound quality, convenience and affordable price. However, many users face a typical problem: one of the headphones stops working, does not connect to the phone or simply “silent” while the second one correctly reproduces sound. 90% of the time, the reason lies in the loss of synchronization between the left and right headphones – they stop “seeing” each other as a pair.

In this article, you will find step-by-step synchronization instructions for all popular Mi True Wireless models: from budget Basic to budget. 2/Basic 2S before the flagship Air 2/Air 2S/Air 3. We'll look at both the standard reset method and the alternative methods if the headphones are stubbornly reluctant to connect, and you'll also learn why the problem comes back and how to avoid it.

Before you start setting up, make sure that:

• 🔋 Both headphones are charged (indicators burn or flash when removed from the case).
• 📱 Your smartphone supports Bluetooth. 4.2 or newer (for Air) 2S/Air 3 Bluetooth is needed 5.0+).
• 🔄 Headphones are not connected to other devices (for example, to a laptop or tablet).

Why are Xiaomi headphones out of sync?

Mi True Wireless Earphones synchronization failures due to Bluetooth Low Energy protocol (BLE), And that's the reason why you're connected to the headphones:

Hardware failures:

• 🔌 Sharp removal of headphones from the case during charging (may interrupt the process of updating the firmware).
• 📶 Interference from other wireless devices (Wi-Fi routers, microwaves, other headphones).
• 🔋 Discharge of one of the headphones up to 0% (critical discharge knocks the pair settings down).

Programmatic errors:

• 🤖 Firmware failure after automatic update (relevant to Air) 2S/Air 3 supportive MIUI Pop-up).
• 📱 Bluetooth cache conflict on your smartphone (especially after the update) Android/iOS).
• 🔄 Incorrectly disconnecting the headphones from the device (for example, through “Forget device” for only one headphone).

💡

If the headphones are out of sync after a fall or impact, the problem may be mechanical (the contact in the case or the earpiece itself is damaged), in which case synchronization with software methods will not help - repair is required.

Standard method of synchronization: reset via case

This is a universal method that works for all Mi True Wireless Earphones models except the Air 3 Pro (which require a separate algorithm).

• 🎧 One headphone connects to the phone, the other does not.
• 🔊 The sound is only in one headphone.
• 🔄 Headphones are not defined as a pair in Bluetooth settings.

Step-by-step algorithm:

1. Put both headphones in the case and close the lid for 10 seconds.
2. Open the case cover and hold the sync button (located on the back of the case) for 15-20 seconds until the indicator starts flashing red and white alternately.
3. Close the case cover for 5 seconds, then open it again.
4. Get both headphones out – they should automatically sync (the indicators will light up white and start flashing synchronously).
5. Connect your headphones to your phone via Bluetooth as a new device.

Alternative synchronization methods

If a standard reset didn't work, try one of these. They vary depending on the headphone model and the firmware version.

Method 1: Forced reboot of headphones

It is a good idea to use Mi True Wireless Earphones Air. 2/Air 2S:

1. Get both earphones out of the case.
2. Press and hold the touchpads on both headphones simultaneously for 10 seconds until you hear the beep.
3. Put the headphones back in the case, close the lid for 10 seconds.
4. Take out and check the synchronization (the indicators should flash synchronously).

Method 2: Reset via Mi Earphones

Relevant to Air 2S/Air 3 proprietary:

1. Install the Mi Earphones app (available for Android and iOS).
2. Connect at least one headphone to your phone via Bluetooth.
3. Open the application, go to Settings → Resetting headphones.
4. Confirm the reset and wait for the reboot (earphones themselves synchronized).

💡

For Air 3 Pro models, resetting through the Xiaomi Wear application is mandatory - the hardware button on the case may not work due to the features of the firmware.

Method 3: Manual Bluetooth connection (for power users)

If the headphones are defined as two separate devices (Mi True). Wireless_L and Mi True. Wireless_R), do the following:

1. On the phone, open Settings → Bluetooth.
2. Remove both headphone records (“Forget the device”).
3. Turn on the search mode on the phone.
4. Take both headphones out of the case and wait until one Mi True Wireless Earphones device appears on the list.
5. Connect to it – the headphones sync automatically.

⚠️ Note: If two separate devices are displayed in the Bluetooth list even after reset, it is a sign of hardware malfunction of one of the headphones. Try connecting each headphone separately - if one of them does not make sound when connected, repair is required.

Frequent Mistakes and How to Avoid Them

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

• 🚫 Resetting only one earpiece, which results in a complete pair of earphones being out of sync. Always reset both earphones at the same time.
• 🚫 Use a non-original case, cheap analogs may not provide the right contact for charging and synchronization.
• 🚫 Interrupt the reset process. If you release the button on the case before the time, the headphones can "hang" in the update mode.
• 🚫 Connecting your headphones to multiple devices at the same time leads to a conflict of Bluetooth profiles.

How to prevent future desynchronization:

• 🔋 Watch the charge of the case and headphones (do not allow a discharge below 10%).
• 📱 Clean Bluetooth cache on your smartphone regularly (in Settings) → Annexes → Bluetooth → Memory. → Clear the cache).
• 🔄 Always turn off your headphones via Bluetooth menus, rather than just putting them in a case.
• 📦 Keep your headphones in your case when not in use – this protects against accidental pressing and interference.

Synchronization Features for Different Models

Each Mi True Wireless Earphone has its own synchronization nuances, and the key differences below are the key ones.

Mi True Wireless Earphones Basic 2/Basic 2S

The easiest to set up, but sensitive to the Bluetooth version on your smartphone:

• 📱 Android 8 and below may not connect to both headphones at the same time (requires a phone software update).
• 🔋 If the indicator on the case flashes red when reset, the headphones are discharged. Charge the case to 100% and try again.
• 🎵 For mono-connection (for example, only the left earpiece), hold the touch panel on the desired earpiece for 3 seconds after extraction from the case.

Mi True Wireless Earphones Air 2/Air 2S

Support Bluetooth 5.0 and have improved communication stability, but are sensitive to interference:

• 📶 In places with strong Wi-Fi signals (such as offices) they may become out of sync.
• 🔊 To reset audio settings (for example, if the bass is missing), hold the touch panels on both headphones for 5 seconds until the double signal.
• 📱 iPhone may need to allow access to microphone in Bluetooth settings.

Mi True Wireless Earphones Air 3/Air 3 Pro

The most advanced, but also the most capricious in the setting:

• 🤖 Require Xiaomi Wear apps to work properly (including resetting).
• 🔄 Supports fast switching between devices, but this can cause conflicts. disable the feature in the app settings if the headphones often dissynchronize.
• 🎛️ Have a low latency mode (Low Latency Mode), which can interfere with synchronization.

💡

For the Air 3 Pro, disable the Dual Device Connection feature in the Xiaomi Wear app before reset.This eliminates 80% of sync issues.

What do you do if nothing helps?

If you've tried all the methods and the headphones are still out of sync, the problem could be hardware.

If the headphones are warranty:

• Contact the official Xiaomi service with a check and a box.
• Please indicate that the problem occurred without mechanical damage (this is important for the warranty case).
• If the service refuses to accept headphones, demand a written refusal with a reason.

⚠️ Warning: Don't try to disassemble your headphones or case yourself - this voids the warranty. 95% of the time, Mi True Wireless Earphones hardware malfunctions are fixed by replacing the module, not repairing it.
