How to connect two Xiaomi headphones to the same phone: 5 working ways

Connecting two pairs of Xiaomi wireless headphones to a single smartphone is a challenge that comes up in different situations, from listening to music together to using one headphone from each pair. However, standard Bluetooth settings on Android usually do not allow you to connect more than one audio device at a time. In this article, we will discuss 5 proven ways to synchronize two Xiaomi headphones (including the models of Redmi AirDots, Mi True Wireless, Buds 4 and others), and talk about the possible limitations and nuances.

It’s important to understand that not all models support simultaneous connection to a single source. For example, the budget Redmi AirDots 2 can only work separately, while the flagship Xiaomi Buds 4 Pro supports Dual Audio (but require special settings). We tested all methods on Xiaomi, Redmi, POCO smartphones with MIUI 12-14 firmware and HyperOS, so the instructions are relevant for 2026.

1. Method: Use of Dual Audio Function (MIUI/HyperOS)

The easiest method is to take advantage of the built-in Dual Audio feature available on Xiaomi smartphones with MIUI 12 and later (including HyperOS), which allows you to transmit sound to two Bluetooth devices simultaneously, but does not work with all models of headphones.

To activate the mode:

• 📱 Open the Settings. → Connections and sharing → Bluetooth.
• 🔗 Connect the first pair of headphones (e.g. Xiaomi Buds) 3T).
• 🎧 Click on the gear icon next to the connected headphones and select Dual Audio Out (or Dual Audio in English firmware).
• 🔄 Connect a second pair of headphones through the same Bluetooth section.

Limitations:

• ❌ It does not work with headphones that use different protocols (for example, AirDots S and Buds 4 Pro).
• ❌ Possible sound delays (up to 200 ms) due to codec differences (SBC, AAC, aptX).
• ❌ On some models (Redmi Note 10 and older) the function may not be available.

2. Method: SoundAssistant app (for Samsung, but it works on Xiaomi too)

If your firmware doesn’t have Dual Audio, you can use Samsung’s third-party SoundAssistant app.Although it’s designed for Galaxy devices, it’s successfully installed on Xiaomi via a new app. APK-file.

Instructions:

1. Download SoundAssistant APK (version 3.1.05 and later).
2. Install the file by allowing installation from unknown sources (Settings → Applications → Special Access → Install Unknown Applications).
3. Open the app and go to Dual Audio.
4. Connect both pairs of headphones via standard Bluetooth.
5. Turn on the Double Sound switch and select both devices.

Important: The application may not work properly on firmware below MIUI 13 due to Bluetooth API limitations.

3. Method: Use of Bluetooth splitter (hardware method)

If software solutions are not suitable, you can use a Bluetooth transmitter with support for two connections, for example, the Avantek BTA-200 or 1Mii B06 Plus adapters allow you to connect two pairs of headphones to a single source (smartphone, TV, PC).

How it works:

• 🔌 Connect the transmitter to the 3.5 mm connector or through USB-C (model-wise).
• 📶 Activate Dual Link on the transmitter (usually with a long push of a button).
• 🎧 Connect both pairs of Xiaomi headphones to the transmitter.

⚠️ Attention: Cheap Bluetooth transmitters (up to 1,000) ₽) They often have a high latency and do not support modern codecs (aptX, LDAC). Before buying, check compatibility with your Xiaomi headphones.

4. Method: Connection via computer (Windows/macOS)

If you need to connect two Xiaomi headphones to a PC or Mac, you can use built-in operating system features or third-party utilities. For example, Windows 11 has support for Stereo Mix, and macOS has support for Audio MIDI Setup.

For Windows:

1. Connect both pairs of headphones via Bluetooth.
2. Open the Control Panel → Sound → Recording.
3. Turn on Stereo Mix (if not, right-click → Show disabled devices).
4. In the Playback section, select both devices and install them as the Device by default.

For macOS:

1. Open the Audio MIDI Setup (via Spotlight).


2. Press "+" → "Create a device with multiple outputs".




3. Select both pairs of headphones in the list.




4. In the audio settings (Apple menu → System settings → Sound), select the device you created.

If you don’t see Stereo Mix on Windows, update your sound card drivers through Device Manager or the manufacturer’s website (Realtek, Creative, etc.).

5. Method: Using the AmpMe app (for music synchronization)

If you need to not just connect two headphones, but sync music playback on multiple devices (for example, for a party), use the AmpMe app. It allows you to combine several smartphones into one sound system.

How it works:

• 📱 Install AmpMe on both Xiaomi smartphones.
• 🎵 Select a song from Spotify, YouTube Music or your local library.
• 🔗 Create or join a “Party” in the application.
• 🎧 Connect to each smartphone your pair of headphones.

⚠️ Note: When using AmpMe, the sound will be played with a delay of up to 500 ms due to synchronization over the network.

Frequent problems and their solutions

When connecting two pairs of Xiaomi headphones, there can be errors. Let’s consider the most common and ways to eliminate them:

Additional advice:

• 🔋 Before connecting, charge both pairs of headphones to 100% - discharging one of the devices can interrupt the connection.
• 📲 Update the firmware of the headphones through the Mi Home app or Xiaomi Wear (relevant to Buds) 3/4 Pro).
• 🔄 If the sound is distorted, try changing the Bluetooth codec in the developer settings (Settings) → The phone. → Version. MIUI → 5 times to activate the developer mode).

💡

The most stable method for most Xiaomi models is the use of a Bluetooth transmitter with support for Dual Link. Software solutions (Dual Audio, SoundAssistant) can work incorrectly on budget smartphones.
