We will analyze the typical breakdowns of Xiaomi Mi AirDots, Mi True Wireless, Mi Earbuds and other models, as well as give step-by-step instructions with photos and videos (where this is critical). If your headphones are still warranty — don’t disassemble them, you better contact an authorized service. For other cases, read on.

1. Diagnostics problem: why Xiaomi Mi headphones don't work?

Before you fix it, you need to understand what exactly broke, the main symptoms and their possible causes:

• 🔌 Not included - battery discharged, damaged contacts of the charging case, firmware failure.
• 🎧 One earphone does not work - poor contact in the case, damage to the speaker, failure of synchronization.
• 🔊 No sound or distortion – speaker pollution, Bluetooth incorrect settings, hardware breakdown.
• 🔋 Not charged - battery wear, contact oxidation, cable damage.
• 📱 Do not connect to the phone – failure of the Bluetooth module, conflict with other devices, outdated firmware.

The easiest way to diagnose is to try headphones with another device (like a tablet or laptop). If the problem recurs, it's the headphones themselves. If not, look for the reason in your smartphone (see section 3).

Also pay attention to the indicators on the case and headphones:

• 🟢 Green flashing - charging is going normally.
• 🔴 Red flashing – discharge below 10% or error.
• 🟡 Yellow/orange – headphones in pairing mode.
• 💙 Blue – Active Bluetooth connection.

2. resetting the Xiaomi Mi headphones to factory

If the headphones are buggy, out of sync, or out of sync, the first thing you need to do is reset them to factory settings, which will remove all the saved connections and return the original settings.

The instructions are suitable for most models: Mi AirDots (Pro, Youth, SE), Mi True Wireless Earbuds (Basic, 2, 3), Mi Earbuds (Basic, Pro).

For Mi AirDots Pro 2 and newer models, the algorithm is slightly different:

1. Put the headphones in the case.
2. Open the lid.
3. Press and hold the touchpad on both headphones simultaneously for 10 seconds until the indicators start flashing red and white.
4. Wait for the reset (the indicators will go out and light up again).

Important! After reset, the headphones can automatically go into pairing mode (the indicator flashes white). If this does not happen, press and hold the button on the case for 3 seconds.

💡

Resetting solves 60% of software problems with Xiaomi Mi headphones, including connection errors and desynchronization of the stereo pair.

3. Xiaomi Mi headphones do not connect to the phone: what to do?

If the headphones are still not connected after reset, the problem may be in the smartphone's Bluetooth module or conflict with other devices.

• 📱 Update the firmware of the smartphone – outdated software can cause conflicts with Bluetooth 5.0+.
• 🔄 Restart your phone – sometimes the Bluetooth module freezes".
• 🚫 Remove all unnecessary Bluetooth devices from the list of connected devices (maximum 7-8 devices).
• 🔌 Turn off the charge saving – it can limit Bluetooth.

If the headphones are connected, but the sound goes only to one headphone, try:

1. Make sure both earbuds are fully charged (the indicators are green).
2. In Bluetooth settings, click on the headphone name and select Disable the stereo (if there is such a point), then connect again.
3. For Android: Go to Settings → System system → Reset → Reset network settings (this will remove all stored Wi-Fi and Bluetooth devices).

💡

On some Xiaomi smartphones (e.g. Redmi Note) 10/11) There's a Bluetooth bug. LE Audio. To get around it, turn off the feature Higher sound quality in the settings of the headphones.

If nothing helps, try connecting the headphones to another device (laptop, tablet) if they work normally – the problem is in the smartphone, if not – in the headphones themselves (see section 5).

4.One Xiaomi Mi headphone doesn't work: reasons and solutions

The most common problem is that one earphone does not make sound, although the indicator is on and the connection is there. The reasons can be both software and hardware.

Software solutions (try in order):

1. Reconnect the headphones: remove them from the list of Bluetooth devices and connect again.
2. Change the earbuds to the ears – sometimes the left/right ear is not assigned correctly.
3. Reset the settings (see Section 2).
4. Update the headphone firmware via the Mi Home or Xiaomi Wear app (if available for your model).

Hardware causes:

• 🔋 Battery discharged in one headphone - put both in the case for 30 minutes.
• 🔌 Bad contact in the case – clean the contacts with alcohol (see section 6).
• 🎛️ The speaker is damaged - if after all the manipulations there is no sound, perhaps the membrane is torn (repair is necessary).
• 📡 Bluetooth antenna failure – if the headphone connects but the sound is interrupted, the antenna may be damaged (often after falls).

A critical nuance: if one earphone flashes red and the other flashes white, it means that the stereo pair is desynchronized, solved only by a complete reset (section 2) or flashing (section 7).

💡

To check if the speaker is working, hold the earphone to your ear and turn on the music at maximum volume. If you hear a quiet crackle or hiss - the speaker is alive, the problem is in the settings or connection.

5. Xiaomi Mi headphones don't charge: what to do?

If the indicator on the case does not burn when connecting to charging or the headphones discharge in a few minutes, the problem may be:

• 🔌 Charging cable or power supply – try another cable (preferably the original USB-Type-C).
• 🔋 Case or headphone battery – if the case is charged, but does not give charge to the headphones, contacts may be worn out.
• 🧲 Oxidation of contacts - over time, plaque appears on metal contacts, preventing charging.
• 🔥 Battery bloating – if the case is swelled or deformed, do not use it – it is dangerous!

Step-by-step instructions for diagnosis:

1. Connect the case to the charger and check if the indicator is on (should be red or orange).
2. If the indicator is not on, try another cable and socket.
3. If the case is charging but the headphones are not, clear the contacts (see next section).
4. If the case is not charged at all, check it for bloating or mechanical damage.

Attention! If the case swells or deforms, don't try to disassemble it, because lithium-ion batteries can ignite if damaged.

6.Cleaning contacts and disassembling the Xiaomi Mi case

If the headphones don't charge or are intermittently connected, the cause may be contamination or oxidation of the contacts.

• 🧴 Cotton swabs.
• 💧 Isopropyl alcohol (70% and higher) or contact cleaning fluid.
• 🔍 Lupa (optional, for accuracy).
• 🧲 Magnetic screwdriver (if you need to analyze the case).

How to clean contacts:

1. Wet the cotton swab in alcohol and gently wipe the metal contacts on the headphones and inside the case.
2. Let it dry for 5-10 minutes (do not use a hair dryer!).
3. Check if the plaque has disappeared - if not, repeat the procedure.

If cleaning didn't work, you might need to disassemble the case. It's a risky procedure -- you could damage the plumes or the battery. Do this only if you have experience in electronics repair!

7. Reflashing headphones Xiaomi Mi (for advanced)

If the headphones are buggy after the upgrade or not at all, flashing can help. This is an extreme measure - the wrong actions can permanently put the device out of action. We strongly recommend you do this only if you are confident in your skills!

You'll need firmware.

• 💻 Windows computer 10/11.
• 🔌 USB-Type-C Cable (to connect the case).
• 📁 Firmware for your model (download only from official sources, for example, Xiaomi Firmware).
• 🛠️ Mi Flash Tool or Fastboot.

Step-by-step (for Mi AirDots Pro 2):

1. Download the firmware for your model (for example, MSD08LM_pro_global_2.7.1.0).
2. Connect the case to the computer with the lid open (earphones must be inside).
3. Press the button on the case for 10 seconds until the computer identifies the device as Qualcomm. HS-USB QDLoader 9008.
4. Launch the Mi Flash Tool, select the downloaded firmware and press Flash.
5. Wait for the process to finish (5-10 minutes).

Warning! Flashing deletes all data and can lead to loss of warranty. If the headphones don't turn on after firmware, try repeating the process with another version of the software.

💡

Flashing helps in 30% of cases of "bricking" of headphones after a failed update, but if the problem is hardware (for example, a burnt controller), firmware will not help.
