How to properly link two headphones Xiaomi: 5 working ways + problem solving

Have you bought a second Xiaomi headset and want to use both headphones at the same time? Or has one headphone stopped syncing with the other after the upgrade? The problem of connecting two wireless headphones Redmi Airdots, Mi True Wireless or other Xiaomi models is common — especially after resetting or connecting to a new device. In this article, we will discuss all the current ways of syncing (including hidden MIUI functions), explain why the headphones can not communicate, and give step-by-step instructions for Android, iPhone and PC.

It's important to understand that the process of connecting two headphones to each other is different from connecting them to a smartphone. Even if both headphones are visible in the list of Bluetooth devices, this does not guarantee that they are synchronized with each other. We will show you how to check their connection, what to do if one headphone is working and the other is silent or making intermittent sound, and how to avoid typical errors when setting up.

1.Why aren't the two Xiaomi headphones communicating?

Before we get to the instructions, let’s take a look at the main reasons why Xiaomi headphones may not sync:

• 🔋 A discharged battery in one of the headphones (even at 10% charge, communication can be interrupted).
• 🔄 Resetting the settings of one headphone without a second (for example, after prolonged inactivity).
• 📱 Firmware conflict – if the headphones were updated separately through different devices.
• 🎧 Hardware malfunction of the microphone or Bluetooth module (more common after falls).
• 🔗 Connect to multiple devices at the same time (earheadphones forget each other).

The most common situation is when the user tries to connect the headphones to a new smartphone, but forgets to first sync them with each other, as a result, one headphone connects as a mono headset, and the second remains inactive, and the problem can occur after updating the MIUI firmware on the smartphone or the headphones themselves (for example, in the models of Redmi Buds 4 Pro or Xiaomi FlipBuds Pro).

⚠️ Note: If the headphones have never worked in a pair (for example, bought separately), their synchronization may not be possible due to different versions of the firmware.

Method 1: Standard button synchronization (for most models)

This method is suitable for most Xiaomi wireless headphones, including:

• 🎵 Redmi Airdots (all generations)
• 🎵 Mi True Wireless Earphones 2/2S
• 🎵 Xiaomi Air 2/2 SE
• 🎵 Redmi Buds 3/4 Lite/Pro

Instructions:

1. Place both headphones in a charged case and close the lid for 10 seconds.
2. Get them out at the same time – they should automatically turn on.
3. Press and hold the touchpad on both headphones for 5-7 seconds until the red and white light flashes (pairing mode).
4. Wait 15-30 seconds – the headphones should synchronize with each other (the indicators will start flashing synchronously).
5. Connect them to your smartphone via Bluetooth.

If the indicators are not flashing synchronously or one earphone does not respond to pressing, try resetting the settings (see method 3).

3. Method 2: Sync through the Xiaomi Wear or Mi Fit app

For models with firmware support through proprietary software (for example, Redmi Buds 4 Pro, Xiaomi FlipBuds Pro), you can use official applications. This is true if the standard method did not work or the headphones were updated separately.

Step-by-step:

1. Install the app: 📱 For Android: Xiaomi Wear (or Mi Fit for older models). 🍎 For iOS: Mi Fit.

Devices → Add the device

Select your headphone model and follow the instructions on the screen.

firmware update

reset

⚠️ Warning: If after updating the firmware headphones stopped working at all (do not turn on, do not blink), perform a full reset via hold the button for 20 seconds (up to triple blinking red).

Method 3: Hard resetting (if the headphones are "detached")

If the headphones were previously paired but stopped syncing after connecting to another device or upgrading, a full reset will help, which will return them to factory settings.

Instructions for different models:

• 🔴 Redmi Airdots (1/2/3 generation, Air 2: Put the headphones in the case, close the lid. Hold the button on the case (near the case). USB-port 10 So you take out the headphones, they'll automatically reset.
• 🔵 Mi True Wireless 2/2S, FlipBuds Pro: Hold the touchpads on both headphones at the same time 15 Repeat the pairing procedure until the red flashes. 1).
• 🟢 Redmi Buds 3/4 Pro: Three quick taps on the left earphone touchpad. Wait. 5 Seconds – the voice signal “Reset” should sound".

💡

If one headphone does not turn on after reset, try charging it separately in the case for 1 hour - sometimes the battery discharge blocks the start.

After reset, the headphones will not automatically connect - they need to be re-coupled (see method 1 or 2). If the reset does not help, the problem may be a hardware malfunction (for example, a damaged Bluetooth module).

5. Method 4: Synchronization via PC (Windows/macOS)

If the headphones don’t want to communicate via a smartphone, you can try using a computer, a method that is suitable for models that support dual connectivity (for example, Redmi Buds 4 Pro or Xiaomi Air 2S).

Step-by-step instructions for Windows 10/11:

1. Open Settings → Devices → Bluetooth and other devices.
2. Click Add Add the device → Bluetooth.
3. Hold the button on the headphones until pairing mode (see method 1).
4. When two devices appear on the list (e.g., "Mi True") Wireless_XXX_L" And "Mi True" Wireless_XXX_R"), Just connect the right one.
5. Wait for automatic synchronization (can take up to 1 minute).
6. Check the sound through Control Panel → Sound – both headphones should be displayed as one device.

For macOS:

1. Open System settings → Bluetooth.
2. Hold the button on the headphones until you blink white.
3. In the list of devices, select the right and wait for the left connection.

⚠️ Note: Windows sometimes requires manual stereo settings (A2DP) For headphones, for this: Go to Device Manager. → Sound, video and gaming devices. Find your headphones, right-click. → Properties → Driver. → Update.

Method 5: Manual connection via engineering menu (for advanced)

If all previous methods have failed, you can try forced synchronization via hidden Bluetooth settings, which is suitable for Android devices with MIUI or pure Android.

Instructions:

1. Activate Developer Mode on Smartphone: Settings → About Phone → MIUI Version (click 7 times)
2. Return to Settings → Additional → For developers and enable Bluetooth debugging.
3. Install the Bluetooth Auto Connect app.
4. Open the app, find your headphones in the list, and select Force Connect.
5. If the headphones are displayed as two separate devices, manually connect the right one, then the left one.

This method doesn’t work on all models, but it can help if the headphones are defined by the system as a mono headset. If you only have one headphone on after you’ve connected, check the sound settings in the Xiaomi Wear app (Song → Stereo Balance).

7.Typical errors and their solutions

Even after successful synchronization, problems can arise, and we will discuss the most common ways to eliminate them:

If none of these methods helped, check:

• 🔌 Case Charge – sometimes a discharged case battery blocks synchronization.
• 📲 Bluetooth version on your smartphone (Redmi Buds 4 Pro requires Bluetooth 5.0)+).
• 🔄 Conflict with other devices – disable all other Bluetooth headsets within a 10-meter radius.

💡

If your headphones are synced but only sounding in one, check the stereo balance in your device's audio settings. On Android, you can do this through Settings → Sound → Left/Right Channel Balance.
