How to connect both headphones Xiaomi Mi True Wireless Earbuds: the complete guide

Xiaomi Mi True Wireless Earbuds (including Basic 2, Air 2, AirDots Pro and others) have become a popular choice due to a combination of price, sound quality and convenience. However, many users face a typical problem: once removed from the case, only one earbud connects, and the second remains silent or not detected by the phone, a situation that arises from a synchronization failure between the headphones, battery discharge of one of them or software errors.

In this article, we’ll look at all the possible ways to connect both headphones, from basic synchronization to forced reset and firmware updates. You’ll learn how to check the battery status of each headphone, why they can “lose” each other after a MIUI update, and what to do if the indicators are not burning as they should.

Before you get into the tricky stuff, make sure that the problem isn't the trivial stuff: the case is charged, the contacts on the headphones are dirty, and the Bluetooth on your smartphone is on, and it's often these little things that cause a single ear connection.

1. Basic synchronization of headphones with each other

The first thing you need to do is force the headphones to sync with each other, a process called peering, and it usually happens automatically when you first connect, and if the sync is lost (for example, after one of the headphones is discharged or a firmware update), you can start it manually.

Here's the step-by-step instruction:

• 🔋 Put both earbuds in a case and close the lid for 10 to 15 seconds, which will reset their current state.
• 🔄 Open the case cover and get your headphones out. They should turn on automatically (the indicators will flash white or red).
• 🤝 Press and hold the touchpads on both headphones simultaneously for 10-15 seconds until the indicators start flashing red and white alternately (this is a sign of synchronization mode).
• 📱 Connect to your headphones via Bluetooth on your phone. One name should appear on the list of devices (for example, Mi True Wireless Earbuds Basic 2).

If you've done this, you've got both earbuds connected and you're working in sync, you've solved the problem. If you don't, move on to the next section.

2. Checking battery charge and indicators

A common cause of single ear connection is a dead battery in one of the headphones, and the case may show a charge, but the earphone itself does not turn on.

• 🔋 Look at the charge indicators: 🟢 Green: Charge above 60%. 🟡 Yellow/orange: 20% to 60 charge%. 🔴 Red – charge below 20% (urgent charging is required). ⚪ White flashing - headphone in pairing mode.
• ⚡ Connect the case to charge for 30 minutes, even if the indicator shows charge. Sometimes the headphone contacts do not fit tightly to the contacts of the case, and the charging goes only to one earphone.
• 🔄 Try to change headphones in places in the case - sometimes it helps to "wake up" the discharged headphone.

If one of the headphones does not respond to charging (the indicator does not light up), try to wipe the contacts on the headphone and in the case with an alcohol wipe. Oxidation or dirt can interfere with charging.

💡

If the headphone is not charging despite the clean contacts, try using another one. USB-cable or power supply. Sometimes a faulty cable does not provide enough current to charge.

3. Resetting headphones to factory settings

If the basic sync didn't work, the next step is to reset the headphones completely, which will bring the headphones back to the box-like state, and often solve connection problems, and notice that after the reset, you have to re-connect the headphones to the phone.

Resetting instructions:

1. Put both headphones in the case and close the lid.
2. Open the lid and take out the headphones - they should turn on automatically.
3. Press and hold the touchpads on both headphones simultaneously for 20 seconds until the indicators start flashing red 3 times in a row (this is a signal of a successful reset).
4. Close the case cover for 10 seconds, then open and pull out the headphones again.
5. Connect to your headphones via Bluetooth as a new device.

After reset, the headphones should sync automatically. If this does not happen, repeat the procedure again, holding the buttons longer (up to 30 seconds).

4. Problems after updating MIUI or firmware headphones

Sometimes connection problems arise after updating the firmware of the headphones or updating MIUI on the Xiaomi smartphone, this is due to changing the Bluetooth protocols or conflicting software versions.

• 📱 Related: Retreat of the update MIUI: If the problem has occurred after the phone update, try to roll back to the previous version. MIUI through settings → The phone. → Updating the system → Three dots (menu) → Select the service pack. Select the older version if it is stored in the device memory.
• 🎧 Headphone firmware update: Launch the Mi Home or Xiaomi Wear app, find your headphones in the device list and check for updates. Sometimes fresh firmware fixes sync errors.
• 🔄 Reset Bluetooth settings on your phone: Go to Settings → Connections → Bluetooth → Settings (cogs) → Reset the settings. Then reset the headphones.

If you’re not using a Xiaomi smartphone (like an iPhone or Samsung), the problem may be that Bluetooth protocols are not fully compatible, in which case you might want to connect your headphones to another device (like a tablet or a laptop) — if both headphones work, the problem is with the phone, not the headset.

5. Hardware malfunctions: when to contact the service

If all software methods have been tried, but one of the headphones still doesn't connect, there's a high probability of hardware failure.

• 🔴 The indicator on the headphone does not light up either when charging or when switching on.
• 🔊 There is no sound even after reset, although the indicator works.
• 💧 The earpiece has been exposed to moisture (even if it is "water resistant»).
• 🔋 The battery is discharged in a few minutes or does not hold the charge.
• 📶 The headphone is determined by the phone, but immediately switches off.

The cost of repairing headphones Xiaomi Mi True Wireless depends on the malfunction:

• 🔧 Battery replacement: ~1 000–1 500 ₽.
• 📡 Replacement of Bluetooth module: ~1 500–2 500 ₽.
• 💧 Cleaning after moisture is injected: ~800–1 200 ₽.
• 🔌 Repair of charging contacts: ~500–1 000 ₽.

If headphones are warranty, do not try to disassemble them yourself - this will void warranty obligations. Contact the official Xiaomi service center with a check and a warranty card.

💡

Before visiting the service, check if the warranty period has expired (usually 12 months from the date of purchase). If the headphones were bought in the official Xiaomi store, the warranty is valid without a check - by serial number.

6. Alternative ways of connecting (for experienced users)

If standard methods don’t work, you can try non-obvious solutions that sometimes help “resuscitate” headphones.

• 🔌 Connecting through a third-party app: Apps like Bluetooth Auto Connect or Earbuds Battery sometimes allow you to force headphones on, even if standard Bluetooth refuses to see them. Install such an app from Google Play, give it Bluetooth access and try to connect again.
• 📡 Changing Bluetooth regional settings: On some firmware MIUI Change the Bluetooth region to Europe or the United States helps. Use the engineering menu to do this (enter ##4636## in the phone number, select Phone Information). → Wi-Fi settings → Menu (three dots) → Bluetooth Region).
• 🔄 Reflashing headphones via PC: For models AirDots Pro and Air 2 there are informal firmware that can be installed through special utilities (for example, QCC30xx Tool.This method is risky and requires experience, but sometimes saves the "bricks" after a failed update.

⚠️ Warning: Using an engineering menu or unofficial firmware can lead to a complete loss of performance of the headphones.

If you're not sure about yourself, you should see a specialist. Wrong actions can turn headphones into useless plastic.

7. Prevention of connection problems

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

• 🔋 Charge your headphones regularly, keeping them from full discharge. It is optimal to put them in the case after each use.
• 🧼 Clean contacts on headphones and in a case once a month with a cotton swab soaked in alcohol.
• 📱 Update the headphone firmware and MIUI on your phone, but don’t install the beta versions – they often contain bugs.
• 🌡️ Avoid overheating and cold. Do not leave your headphones in the sun or near heat sources (e.g., on a car torpedo).
• 💧 Dry your headphones after moisture is injected, even if they have protection. IPX4. Use silica gel packs for storage.

If you use headphones with multiple devices (such as a phone and laptop), disconnect them from the previous one before connecting to the new device via the Bluetooth menu.
