How to sync headphones Xiaomi Earphones with each other: the complete guide

Xiaomi Earphones wireless headphones have become an integral part of everyday life due to the convenience, sound quality and affordable price. However, many users face the problem when one of the headphones stops working or does not sync with the pair one, which is especially unpleasant if you have just unpacked a new device or updated the firmware. Most of the time, the problem is solved in a few minutes, but you need to know the right sequence of actions.

In this article, we will discuss in detail how to synchronize headphones Xiaomi Earphones with each other for all popular models – from the budget Redmi AirDots to the flagship Xiaomi FlipBuds Pro. You will learn not only standard pairing methods, but also hidden features that will help restore communication between headphones if they are “detached”.

Why Xiaomi headphones lose synchronization?

Before we get to the instructions, it is important to understand why the headphones stop working synchronously, and there may be several reasons, and understanding them will help to avoid problems in the future:

• 🔋 Battery discharge - if one of the headphones is completely discharged, it can "fall off" from the steam one, and after charging, it will not automatically restore communication.
• 📱 Firmware failure – after updating the software through the Mi Home or Xiaomi Wear application, the pairing settings sometimes get lost.
• 🎧 Mechanical damage – falls or bumps can disrupt contacts inside the enclosure, especially in budget models.
• 🔄 Manual shutdown – if you manually disabled one earphone in Bluetooth settings, the system may perceive this as a command to break a pair.
• 📡 Interference from other devices – wireless headphones, routers at 2.4 GHz or microwave ovens working nearby can interfere with stable communication.

In 80% of cases, the problem is solved software-by resetting or re-synchronizing the headphones, but if one of the headphones does not respond to the pressing of the buttons and does not charge, this may indicate a hardware malfunction, and this will already require repair.

Preparing for synchronization: what to do in advance

Before you start pairing your headphones, follow a few simple steps that will save time and help you avoid typical mistakes:

1. Charge the case and headphones – make sure the indicators on the case are green or white (depending on the model). If the battery is discharged below 20%, the synchronization may not be correct.
2. Update your firmware – check the relevance of the software through the Xiaomi Wear app (for new models) or Mi Home (for old ones).Old firmware often causes failures.
3. Disable other Bluetooth devices – temporarily deactivate your smartwatch, speakers, or second pair of headphones to avoid conflict.
4. Check your physical condition, check the contacts on your headphones and in the case for oxidation or contamination, and clean them carefully with a cotton swab dipped in alcohol if necessary.

If you've tried to sync your headphones before and you've failed, reset to factory settings.

1. Put both headphones in the case and close the lid.
2. Press and hold the button on the case (if any) for 10-15 seconds until the indicator flashes red and white.
3. For models without a button (e.g. Xiaomi Air 2 Pro), the reset is done via the app: Device Settings → Reset.

Standard synchronization of headphones Xiaomi: step-by-step instructions

If the headphones are new or you just reset them, follow this instruction.It's suitable for most models, including the Redmi AirDots 2/3, Xiaomi Air 2/2S/2 Pro and FlipBuds Pro.

1. Remove the headphones from the case, they should automatically turn on. If this does not happen, press and hold the touchpad on each earphone for 3-5 seconds until the white indicator flashes.
2. Activate pairing mode: For models with a button on the case, press and hold it for 3 seconds until the indicator flashes quickly. For models without a button, touch and hold the touchpad on the right earbud for 10 seconds.

Put it on the phone.

• Open the settings → Bluetooth on your smartphone.
• In the list of available devices, find Mi True Wireless Earphones (or the name of your model) and select it.
• Confirm the pairing if necessary.
• Check the synchronization — after you connect, both earbuds must emit an audible signal (usually a short squeak). If only one sound comes from, repeat the process.

Important: For models Xiaomi Air 2 Pro and later after the first connection may require the installation of additional software through the application Xiaomi Wear. Without this, some functions (for example, noise reduction) will not work.

💡

If the headphones are not defined by the phone, try connecting them to another device (tablet or PC), which sometimes helps wake up the Bluetooth module.

What to do if the headphones are not synchronized?

If the standard procedure didn't work, don't panic. Here's a troubleshooting algorithm:

1. Check the charge: Put the headphones in the case and wait until the indicators turn green (full charge). If the indicator flashes red, the case is discharged, plug it into charging for 30 minutes.
2. Perform Forced Reset: For Redmi AirDots: press the button on the case 4 times in a row, then hold on for 10 seconds. For Xiaomi Air 2/FlipBuds: tap the sensor on the left earphone 5 times, then hold on for 15 seconds.

Update the firmware manually

• Download the latest version of the software for your model from the official Xiaomi website.
• Connect your headphones to your PC via Bluetooth and use the Mi Flash Tool (instructions in the archive with firmware).
• Check on another device -- try connecting the headphones to another smartphone or laptop. If the problem persists, it indicates a hardware defect.

⚠️ Note: if one of the headphones stopped turning on or does not charge after reset, do not try to disassemble it yourself. Budget models (for example, Redmi AirDots) often use adhesive joints, and if you open it neatly, you can damage the board.

If none of these things work, go to the service center. In Xiaomi headphones, the warranty covers hardware malfunctions, but not damage caused by falling or getting moisture.

Synchronization features for different models Xiaomi Earphones

Despite the general principle of operation, each model has its own nuances.

Redmi AirDots 1/2/3

The most budget-friendly headphones in the lineup, the main problem is a weak Bluetooth module that can lose communication at a distance of more than 5 meters.

• Always start with the right headphone (main).
• If the headphones don’t match, put them in a case, close the lid and wait 30 seconds.
• To reset, hold the button on the case for 20 seconds (until flashing in red and white).

Xiaomi Air 2 / Air 2S / Air 2 Pro

These models support advanced codec (AAC, aptX), but sometimes synchronization problems arise due to firmware conflict.

• Update the firmware through Xiaomi Wear (Firmware section).
• If the headphones are connected separately, in the Bluetooth settings of the phone, select "Forget the device" and repeat the pairing.
• To reset, tap the sensor on both headphones simultaneously for 15 seconds.

Xiaomi FlipBuds Pro / Buds 4 Pro

Flagship models with active noise cancellation, where most problems arise after a software update, to restore synchronization:

• Use only the original Xiaomi Wear app (not Mi Home!).
• After reset, wait until the headphones are automatically updated to the latest version.
• If the sound is interrupted, turn off the Dual Device Connection feature (connecting to two devices at the same time).

💡

For noise-cancelling models (FlipBuds Pro, Buds 4 Pro) after reset, you may need to recalibrate the microphones. To do this, select "Sound settings → Calibration" in the Xiaomi Wear app.

How to check if the headphones are synchronized correctly?

Even if the headphones are connected to the phone, it does not guarantee that they are correctly synchronized with each other.

1. Sound test: Turn on the music and turn on each earphone with your palm, the sound should disappear completely when you close any of them, and if the sound continues in one earphone, the sync is lost.
2. Check Bluetooth settings: On Android: open Settings → Bluetooth, click on the gear icon next to the headphones and see status. It should be "Stereo" (not "Mono"). On iOS: Settings → Bluetooth, next to the headphone name, the "i" icon in the mug should be on, and when you press it, the "Separate Device" option should be displayed.

Microphone test

• Record the voice message. The sound should be recorded equally clearly from both headphones.
• If the microphone only works in one, reset and repeat pairing.

If at least one of the tests fails, repeat the sync procedure or contact the service. Xiaomi headphones often have the problem of one headphone connecting as a mono (for example, only the right one), This is treated by resetting or updating the firmware.

⚠️ Attention: In models with support LC3-codec (e.g. Xiaomi Buds 4 Pro) may need to re-pair the phone after updating the firmware, even if the headphones have already been connected before.

Frequent User Mistakes and How to Avoid Them

Many synchronization problems are caused by users' incorrect actions, and here are the most common errors and ways to prevent them:

• 🚫 Use of a non-original charger – cheap cables or adapters may not provide enough current, causing the headphones to not fully charge. Always use an output charger. 5V/1A Or the original Xiaomi cable.
• 🚫 Interrupting the firmware update process - if you have started updating through the app, don't close it or turn off Bluetooth until a message of successful completion appears.
• 🚫 Storing headphones out of the case – if you leave the headphones outdoors for more than 24 hours, they will automatically discharge to zero and they will have to be reset.
• 🚫 Ignoring app updates - Xiaomi Wear and Mi Home regularly receive patches that fix pairing errors.The outdated version of the app may not see new headphone models.
• 🚫 Connecting to multiple devices at the same time – if you use the Dual Connection feature (for example, for your phone and laptop), sometimes the headphones “muttle” and lose sync.

Another common mistake is trying to synchronize headphones from different pairs, and even if they look the same, each earpiece is tied to its own case at the hardware level, and you can't connect the left earphone from one pair to the right from the other.
