How to connect two Xiaomi headphones to each other via Bluetooth: full instructions with solutions to problems

Xiaomi wireless headphones have long since ceased to be a luxury — they have become an integral part of everyday life. But what if you want to use two headphones simultaneously to listen to music from the same device or share sound with another? In this article, we will discuss how to properly connect Xiaomi headphones with each other over Bluetooth, which models support the TWS function, and what to do if synchronization does not work.

Many users mistakenly think that it is enough to simply turn on both headphones and they will automatically connect. In practice, the process requires knowledge of nuances, from support for Bluetooth 5.0+ protocol to the correct sequence of actions in the settings. We will look at the official methods for models of Redmi AirDots, Mi True Wireless Earphones and others, as well as alternative methods for devices without native support for dual connection.

Importantly, not all Xiaomi headphones can work in tandem with each other. For example, Redmi Buds 3 Lite do not sync with Mi Air 2 SE – this requires the same model or universal protocol support. At the end of the article you will find a table of compatibility of popular models.

What Xiaomi Headphones Support Connection to Each Other

The dual-earhead synchronization feature is called TWS (True Wireless Stereo), or Dual Connection, and it's not available on all models, but only on those where the manufacturer has provided hardware support.

• 🔹 Redmi AirDots Series: Starting with Redmi AirDots 2 (2020) and later. Lite versions (e.g. Redmi Buds 3 Lite) often lack this feature.
• 🔹 Mi True Wireless range: all models except the most budget (for example, Mi Basic). 2/2S/2 Pro.
• 🔹 Flagship models: Xiaomi FlipBuds Pro, Buds 4/4 Pro supports advanced protocols, including synchronization with other devices of the brand.
• 🔹 Bluetooth protocol: Bluetooth 5.0 or later is required.Older versions (4.2) do not support dual connection.

To find out exactly if your model supports the feature, check the specifications on the official Xiaomi website or in the Mi Home app. If the specifications indicate “Dual connection” or “TWS” – then the headphones can be synchronized.

Note that even if your headphones support TWS, they may not sync with models from another line. For example, the Redmi AirDots 3 Pro will not work in tandem with the Mi Air 2, despite similar specs.

Preparing headphones for synchronization

Before you connect the headphones, you need to follow several mandatory steps, skipping any of them can cause failures or inability to connect.

Charge both headphones to 100% (the indicator should burn green)

Turn off the headphones (press the power button for 5 seconds before flashing red light)

Remove headphones from the list of conjugated devices on your phone/PC

Update the headphone firmware through the Mi Home app (if available)-->

Pay special attention to resetting, if the headphones have previously connected to other devices, their cache may conflict with the new synchronization.

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the case (if any) or touchpad on the headphones for 10-15 seconds until the indicator starts flashing red and white.
3. Wait for the automatic reboot (the indicator will light up in blue).

If your model supports firmware updates, be sure to check the relevance of the software. Outdated versions often contain bugs that interfere with dual connection. The update is available through the Mi Home app (Device Profile → Software Update).

💡

If the headphones are not identified by the phone after reset, try connecting them one by one, sometimes it helps to pair each headphone sequentially and then remove it from the list of devices.

Step-by-step: how to connect two headphones Xiaomi with each other

The synchronization process depends on the headphone model, but the general scheme looks like this:

1. Turn on both earphones: Take them out of the case (they should automatically turn on). If not, press the touchpad or power button for 3 seconds until the white indicator flashes.
2. Activate pairing mode: On the main (right) headphone, press the touchpad for 5-7 seconds until the indicator flashes red and white. On the second headphone, repeat the action - it should flash blue (ready to connect).
3. Connect the first headphone to the phone: Open Settings → Bluetooth on your smartphone. Select your headphone from the list of available devices (model name will show, for example, Redmi). AirDots_XXX).
4. Wait for automatic synchronization: After 5-10 seconds, the second earphone should connect automatically. Some models (Mi Air 2 Pro) require you to confirm the connection of the second device in the Mi Home application.

If the headphones are not synchronized automatically, try an alternative method:

1. Connect the first headphone to the phone.
2. Turn on the second headphone and press the touch panel on it for 10 seconds until you hear the beep (beep).
3. In the Mi Home app, go to the headphone settings and select Add a second device (if the option is available).

Compatibility table of Xiaomi models for dual connection

Not all Xiaomi headphones can work in pairs with each other, and here is a table of compatibility of popular models (data is up to 2026):

Important: headphones from different lines (for example, Redmi and Mi) almost never synchronize with each other, even if they support TWS. The exception is the flagship models with a universal protocol (for example, Buds 4 Pro).

Common problems and their solution

Even if instructions are executed correctly, users often encounter errors, and consider typical scenarios and ways to fix them:

⚠️ Note: If after synchronization the sound goes only to one headphone, check the audio balance in the settings of the smartphone (Settings) → Sound. → Stereo balance. Sometimes system settings get lost when you connect. TWS-device.

• 🔌 Headphones can't find each other: Make sure both headphones are at least 20% discharged (at low charge, they may not turn on sync mode). Check that the phone is power-saving off - it can block a stable Bluetooth connection. Reboot your smartphone and try again.
• 🔊 The sound is interrupted or delayed: Reduce the distance between the headphones (maximum 1 meter). Disable other Bluetooth devices within range (they cause interference). In the Bluetooth settings of the phone, select Priority Sound Quality (if you have any).
• 🔄 Headphones connect alternately, not simultaneously: Reset your headphone settings (see Preparation section). Update your firmware through Mi Home. Try connecting your headphones to another device (like a laptop).

If the problem persists, check if your model is fake.Counterfeit headphones often mimic Xiaomi's design but don't support key features.The original devices have:

• Serial number on the case and in the application Mi Home.
• Branded packaging with a hologram.
• Support for official updates.

Alternative ways to connect two headphones

If your headphones don’t support TWS, but you want to use them at the same time, there are workarounds:

• 📱 Use Bluetooth Transmitter: Purchase a Bluetooth adapter with Dual Link support (e.g. Avantek) BTD-020). Connect both earphones to the adapter, and it will broadcast the sound synchronously.
• 🎧 Dual audio apps: On Android (version 8.0)+) Use dual audio in Bluetooth settings. On iOS, install the AudioRouter or SoundSeeder app. Limitation: it doesn't work with all headphone models.
• 💻 Connection via PC: On Windows 10/11 Use a Stereo mixer to duplicate the sound on two devices. MIDI multi-output.

For owners of Xiaomi smartphones, there is another way to use the proprietary Mi Dual Audio feature (available on MIUI 12+):

1. Connect the first headphone via Bluetooth.
2. Open Settings → Connections → Bluetooth.
3. Click on the icon. ⚙️ near-ear-ear.
4. Select the Dual Audio and connect the second headphone.

⚠️ Note: Mi Dual Audio may not work smoothly with third-party headphones. Use two Xiaomi devices of the same model for maximum compatibility.

How to check the quality of synchronization

Once you've successfully connected, it's important to make sure that the headphones are working properly.

• 🎵 Synchronicity of sound: Turn on a track with a clear beat (for example, electronic music). Put headphones to your ears - the sound should be simultaneous, without echoing.
• 📶 Connection stability: Step 5-10 meters away from your phone (no obstruction). If the sound starts to break, check for interference (Wi-Fi routers, microwaves).
• 🔋 Battery consumption: Dual-connected headphones discharge 15-20% faster. Check the charge level in the Mi Home app.

If you notice a lag, try:

1. Switch Bluetooth codecs in the developer settings (Settings → About Phone → Build Number (7 taps) → Developer settings → Bluetooth Codec).
2. Select SBC over AAC or aptX – it is less demanding on connection stability.
3. Turn off the absolute volume in the same settings.

💡

If the delay persists after all the manipulations, the problem may be in the headphone hardware, in which case, contact the Xiaomi service center.
