Xiaomi’s wireless headphones (Redmi Buds, Mi True Wireless, FlipBuds, and others) support a paired connection that allows two separate headphones to be used as a single stereo system, which is convenient when you want to share music with a friend, create surround sound, or just use both devices at the same time. However, not all users know how to properly connect Xiaomi headphones with each other — the process may vary depending on the model and firmware version.
In this article, we’ll look at all the current synchronization methods, including manual Bluetooth connectivity, automatic pairing, and solving common problems (e.g., when one earbud doesn’t find the other), and what models support this function, and what to do if standard methods don’t work, starting with the basics, without which the next steps may not work.
Important: Make sure that both headphones are fully charged (at least 50%) and are within range of Bluetooth (up to 10 meters without obstacles) before starting. If the battery is discharged, the pairing process can be interrupted, and the devices can “forget” each other.
Not all Xiaomi models support a paired headphone-to-earphone connection. For example, the budget Redmi Buds 3 Lite or the old Mi Basic Earphones do not have this feature. To check compatibility, refer to the specifications of your model on the official website or in the Mi Home app.
What Xiaomi models support connection between headphones
The dual headphone sync feature is not available in all Xiaomi devices, and here is the current list of supported models (as of 2026):
- 🎧 Xiaomi FlipBuds Pro (all generations) – supports Dual Device Connection mode to connect to two sound sources simultaneously.
If your model isn't listed, it doesn't mean it's definitely not there. Some devices (like Redmi Buds 3 Pro) require a firmware update to activate the mode.
- Open the Mi Earphones app (download from Google Play or the App Store if not already installed).
- Connect the headphones to the phone via Bluetooth.
- Go to the Settings section → Update the firmware.
Critical detail: Xiaomi headphones can only be connected within one model. For example, Redmi Buds 4 Pro do not sync with Xiaomi Buds 3T — Even if both models support the function.
Preparing headphones for synchronization: what to do before connecting
Before you start connecting, follow a few mandatory steps, and ignoring them is the main reason why Xiaomi headphones can’t see each other.
1. Reset the headphone settings (if they have already been connected to other devices).
- Put both earphones in the case.
Press and hold the button on the case (usually located behind) for 10-15 seconds until the indicator flashes red and white.
- Get the headphones out - they should automatically go into pairing mode.
2. Disable headphones from all devices manually:
- On Android: Go to Settings → Bluetooth, find the headphones in the list and click "Forget the device".
- On iOS: Settings → Bluetooth → smack-in-the-ear button → "Forget this device".
3. Check the firmware version through the Mi Earphones app. If an update is available, install it. Older versions of the software may not support pairing.

⚠️ Warning: If one of the headphones has previously been connected to another smartphone or tablet, it may automatically try to connect to it, ignoring the second headphone.
Method 1: Automatic connection via case (for new models)
Modern Xiaomi headphones (such as FlipBuds Pro or Redmi Buds 5 Pro) support automatic synchronization when placed in a case.
- Put both headphones in the case and close the lid.
- Open the lid and wait until the headphones start flashing white (pairing mode).
- Take both earbuds out of the case. They should automatically connect with each other (the indicators will light up blue or stop flashing).
- Now connect them to your phone as a single device via Bluetooth.
If the indicators flash red, it means an error. Try repeating the process or resetting (see Preparation section).
Some models (such as Xiaomi Buds 4) require additional confirmation in the Mi Earphones app:
Open the application after automatic connection.
- Go to Settings. → Dual Audio Mode (or similar item).
Activate the option to connect the second headphone.
💡
If the headphones don't sync automatically, try putting them in a case for 30 seconds, then pull them out and wait 10 seconds. Sometimes this works better than repeatedly opening/closing the lid.
Method 2: Manual synchronization via Bluetooth (universal method)
If the automatic connection didn’t work, use the manual method.It’s suitable for most models, including the Redmi Buds 4 and Mi True Wireless 2.
1. Activate the pairing mode on both headphones:
- Get both earphones out of the case.
Press the touchpad (or button) on the right earphone for 5 seconds until you hear the beep and see a flashing white light.
- Repeat the same for the left earpiece.
2. Connect the first headphone to the phone:
- Turn on Bluetooth on your smartphone.
In the list of available devices, select the name of your right earphone (e.g. Redmi Buds 4 Pro-R).
3. Add a second earpiece:
After connecting the first headphone, go back to the Bluetooth menu.
Find a second headphone (like the Redmi Buds 4 Pro-L) and plug it in.
On some models (FlipBuds Pro) after connecting the second headphone, they will automatically merge into one device.
If the headphones don't come together:
- Open the Mi Earphones app.
- Go to Settings. → Stereo Mode (or Dual Mode).
- Press "Put the second headphone on."
| Model headphones | Does it support automatic synchronization? | Is the Mi Earphones app required? |
|---|---|---|
| Xiaomi FlipBuds Pro | Yes. | No (but recommended for customization) |
| Redmi Buds 5 Pro | Yes. | Yes (for activation) TWS+) |
| Mi True Wireless Earphones 3 | No. | Yes (required) |
| Redmi Buds 4 | Partially (only after update) | Yes. |
⚠️ Note: On iPhone, the process may be different. Some Xiaomi models do not support pairing with Apple devices due to iOS restrictions.In this case, use an Android smartphone for initial synchronization, and then connect the headphones to the iPhone as a single device.
Method 3: Sync through the Mi Earphones app (for older models)
If your headphones don’t support automatic or manual Bluetooth connectivity, try using the official Mi Earphones app.This method works for Mi True Wireless Earphones 2, Redmi AirDots 2 and other models without the feature. TWS+.

3. Open the app and wait until it determines the headphone model.
4. Go to the Settings section → Stereo Mode (or Dual Mode).
5. Click "Connect the second headphone" and follow the instructions on the screen.
The app will prompt you to activate pairing mode on the second headphone (usually you need to hold the touchpad for 3-5 seconds). Once successfully connected, both earphones will work as a stereoopara.

💡
If neither method worked, check if your model supports paired connectivity.Some Xiaomi budget headphones (like the Redmi Buds 3 Lite) are physically unable to work in stereo pair mode with another headphone.
Additional functions with a pair connection
Synchronizing two Xiaomi headphones gives you access to advanced features that are not available when using a single device.
- 🎶 Volumetric sound: In the Mi Earphones app, activate the mode 3D Audio or Surround Sound (Available for FlipBuds Pro and Buds 4 Pro).
- 🔀 Switching between devices: Headphones can be connected to two smartphones at the same time (for example, to a phone and a laptop).
- 🎤 Separate use of microphones: When calling, you can choose which headphone to use for conversation (useful in noisy places).
- 🔋 Optimized consumption: In paired mode, the headphones automatically distribute the load, increasing the running time to 30%.
To activate these functions:
- Open Mi Earphones and go to Settings → Additionally.
- Select the option you want (e.g., Dual Device Connection to connect to two devices).
