How to connect Xiaomi wireless headphones to each other: full instructions for all models

Why Xiaomi Headphones Don’t Connect to Each Other and How to Fix It

Xiaomi’s wireless headphones (including the Redmi AirDots, Mi True Wireless, Buds, and FlipBuds lines) are powered by True Wireless Stereo (TWS), which involves synchronizing the left and right earphones with each other. However, users often face the problem of one headphone not connecting to the other, sounding only in one or the devices are not defined by the smartphone at all.

In this article, we’ll look at all the ways Xiaomi headphones can connect to each other, from standard procedure to forced reset and manual synchronization, and how to check model compatibility, what errors are most common when connected, and how to avoid them. If your headphones stop working in stereo or one of them “falls off” – follow our recommendations in order.

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 5.0 or later (for stable operation) TWS).
• 🔄 Headphones are not connected to other devices (for example, a laptop or tablet).

Standard way to connect: how to synchronize Xiaomi headphones with each other

In most cases, Xiaomi headphones connect automatically when you first remove them from the case, but if you don’t sync, follow these steps:

1. Remove both headphones from the case and wait for the indicators to flash white/blue (search mode).
2. Press the buttons on both headphones for 5-10 seconds until you hear an audible beep (usually a double squeak) that will force you to reset current connections.
3. Put the headphones back in the case, close it for 10 seconds, then pull it out again. They should sync automatically (the indicators will light up in red, then white).
4. Connect to your smartphone: in Bluetooth settings, select the name of your headphones (e.g., Redmi). AirDots_S).

If after these actions the sound is only in one headphone, try:

• 🔄 Reboot your smartphone (sometimes the problem lies in the Bluetooth drivers).
• 📴 Turn off and turn on Bluetooth on your phone again.
• 🔋 Check the charge of the case – if it is discharged, the headphones may not synchronize.

Manual synchronization: if the automatic connection is not working

If the standard method doesn't work, you'll have to force the earbuds to sync manually, which is different depending on the model, but the general algorithm is this:

1. Reset the headphone settings: For Redmi AirDots: press the buttons on both headphones for 15 seconds until the indicators start flashing red and white alternately. For Mi True Wireless 2/3: tap the touchpad of each headphone three times quickly, then hold on for 10 seconds.

Activate the pairing mode

• Put both earphones in the case, close it.
• Remove only the right earphone and hold its button for 5 seconds until blue blinks.
• Get the left earpiece – it should automatically connect to the right (the indicators will light up white).
• Connect to your phone: the name of your headphones will appear in the list of Bluetooth devices (for example, Mi True Wireless). 2_Stereo).

Important: Xiaomi Buds 3/4 Pro headphones sync only through the proprietary Mi Earphones app (available for Android).

Model compatibility table: what Xiaomi headphones can be connected to each other

Not all Xiaomi models support cross-synchronization (e.g., connecting Redmi AirDots to Mi True Wireless 2).

If your model is not in the table, check compatibility experimentally: try to reset both earphones and plug them in manually, but it is not recommended to use headphones from different lines - this can lead to loss of sound or quick discharge.

💡

If you lose one headphone, don’t rush to buy a new set. On AliExpress and in Xiaomi service centers, you can order a separate left/right headphone according to the model article (for example, BHR4255GL for Redmi AirDots 2).

Common Mistakes and How to Fix Them

Even after successful synchronization, users face problems, and here are the most common ones and ways to solve them:

• 🔊 The sound comes only in one headphone: Check the sound balance in the smartphone settings (on Android: Settings → Sound. → Balance stereo. Reset your headphone settings (see section above). Update your headphone firmware through the Mi Earphones app.
• 🔋 One earphone discharges faster: It's normal for TWS-headphones, but if the difference is significant, check the charging contacts in the case.
• 📵 Headphones are not defined by the phone: Remove them from the list of associated devices and reconnect them. Try connecting from another smartphone — if it doesn't work, the problem is the headphones.

⚠️ Warning: If the headphones are still out of sync after all the manipulations, the Bluetooth module in one of them may have failed, in which case only repair or replacement will help.

Firmware Update: Why It Matters for TWS to Work Sustainablely

Many connectivity issues are solved by firmware updates. Xiaomi regularly releases patches for its headphones that fix synchronization errors, improve sound and increase battery life.

1. Download the official Mi Earphones app (available for Android on Google Play).
2. Connect the headphones to your smartphone.
3. Open the application and go to the section Branded firmware (or Update).
4. If a new version is available, click Update and wait for the process to complete (don’t turn off the headphones!).

For iPhone, updating the firmware of Xiaomi headphones is impossible – use an Android device or contact the service center.

💡

Updating the firmware through Mi Earphones takes 5-10 minutes. You can not interrupt the process - this can lead to "bricking" of the headphones (complete inoperability).

Alternative ways to connect: if nothing helps

If the standard methods didn’t work, try these non-obvious solutions:

• 🔄 Connecting via another smartphone: Sometimes the headphones "remember" the wrong settings when you first connect. Try syncing them with another phone and then returning them to the main device.
• 🔌 Charging cable use: Connect the case to charging, then pull out the headphones and hold the buttons on both for 20 seconds.This sometimes resets the "stuck" settings.
• 📡 Changing Bluetooth Region: On some smartphones (such as Xiaomi or Redmi), developers can swap the Bluetooth region to Europe or the US, which sometimes solves connection problems.

If the headphones still don’t work, check them for hardware damage:

• 🔍 Check the charging contacts in the case and on headphones – they should not be bent or oxidized.
• 🎧 Check if the moisture has not got into the speakers (if the headphones are not waterproof).
• 🔋 Make sure that the case gives voltage (plug in to the charging – the indicator should light up).
