How to connect two Bluetooth headphones to a Xiaomi phone at the same time: full instructions

Connecting two pairs of Bluetooth headphones to the same Xiaomi smartphone is a challenge faced by users who want to share audio with a friend or use different devices for music and calls. Unfortunately, standard MIUI settings do not always support this feature out of the box, especially on budget models. However, there are both official and alternative ways to get around the limitations, from the use of built-in features to third-party applications.

In this article, we will analyze all current methods for different versions. MIUI (including MIUI 14 and HyperOS), we will specify compatible Xiaomi models, and warn against typical errors that can lead to connection failures. We will pay special attention to the nuances of working with True Wireless headphones (for example, Redmi Buds or Xiaomi Earbuds) and classic overhead models from Sony, JBL Samsung.

Why Xiaomi limits the simultaneous connection of two headphones?

Smartphone manufacturers, including Xiaomi, often block the ability to connect multiple Bluetooth audio devices at once for three key reasons:

• 🔋 Energy savings: Simultaneous audio streaming to two devices increases the load on the processor and consumes battery power 15-25% faster.
• 🎛️ Bluetooth Protocol Limitations: Most Smartphones Support Profile A2DP (for streaming audio) only for one device at a time, except for the flagship models with Qualcomm Snapdragon 8 Gen 2 chips+ newer.
• 📱 Fragmentation MIUI: on budget devices (for example, Redmi Note 12 or POCO M6) The function can be disabled software even if the hardware supports it.

However, some Xiaomi models officially support Dual Audio (e.g. Xiaomi 13 Pro or Mix Fold 3).To check your device's compatibility, check the table below.

⚠️ Note: On devices with MediaTek Helio (e.g. Redmi) 10C) Even third-party applications may not work due to the chipset's hardware limitations. → The phone.

Dual Audio function in MIUI/HyperOS

If your Xiaomi smartphone supports Dual Audio, you can activate it through standard settings, which works on flagship models with HyperOS or MIUI 14:

1. Open Settings → Connections and Sharing → Bluetooth.
2. Connect the first set of headphones (for example, Xiaomi Buds 4 Pro).
3. Slap the icon. ⚙️ Next to the device name and select Additional settings.
4. Activate the dual audio switch.
5. Connect the second pair of headphones – they should appear in the list of available devices.

If there is no Double Audio, then your model does not support the function at the software level, in which case move on to alternative methods.

Reboot your phone before setting up-->

On some firmware (e.g. MIUI 13 for Xiaomi 12T), the function may be hidden. To unlock it, do the following:

adb shell settings put global bluetooth_dual_audio_enabled 1

This command must be entered through ADB (see the setup instructions at the end of the article). After the device is restarted, the Dual Audio item should appear in the Bluetooth menu.

Alternative methods: applications for audio sharing

If there is no official feature, third-party apps come to the rescue, and they work on the principle of creating a virtual Bluetooth transmitter that duplicates the audio stream across multiple devices.

1. SoundAssistant (from Samsung, but runs on Xiaomi)

Samsung’s app is originally designed for galaxy devices, but it also works well on Xiaomi’s Android 10+ smartphones. Download it from Google Play and follow the instructions:

• 🎧 Connect both sets of headphones via standard Bluetooth.
• 🔊 Open SoundAssistant and go to the Double Audio section.
• 🔄 Select both devices from the list and activate sync.

⚠️ Attention: MIUI 12 and below SoundAssistant can cause stuttering sound. Solution is to disable battery optimization for the application in Settings → Annexes → SoundAssistant → Battery.

2. Bose Connect (for Bose headphones)

If you have at least one pair of Bose headphones (like QuietComfort 45 or SoundLink II), use Bose Connect, which allows you to connect the second pair of headphones through Party Mode:

1. Connect the Bose headphones to your phone.
2. Open Bose Connect and select Party Mode.
3. Connect a second pair of headphones (of any brand) via standard Bluetooth.

The downside is that the sound will only come from the Bose headphones, and the second pair will become a passive receiver, and the sound delay can reach 200-300 ms.

3. Bluetooth Dual Audio (Universal Solution)

Cying's Bluetooth Dual Audio app emulates A2DP support for two devices, which is a fee (about 200 rubles), but offers a free trial period.

• 📥 Install the app from Google Play.
• 🔌 Connect both sets of headphones.
• 🎵 In the main menu of the application, select both devices and click Start.

Important: On Xiaomi with MediaTek processors (like the Redmi Note 11), the app may not work due to the limitations of Bluetooth drivers.

💡

If the sound is interrupted, try to reduce the bitrate of the audio in the application settings to 192 kbps. This will reduce the load on the Bluetooth module.

Connection via Bluetooth 5.2 and LE Audio (for new models)

Xiaomi smartphones on Snapdragon 8 Gen 2 and later (such as Xiaomi 14 or Redmi K60 Ultra) support Bluetooth 5.2 with LE Audio function. This allows you to connect up to several audio devices simultaneously without loss of quality.

1. Update your firmware to the latest version of HyperOS.
2. Go to Settings → Connections → Bluetooth → More
3. Enable the option of Low-Energy Audio (LE Audio).
4. Connect the headphones that support LC3-codecs (e.g. Xiaomi Buds 4 or Sony) WF-1000XM5).

The advantages of LE Audio:

• 🎶 Low latency (up to 20 ms vs. 100–200 ms in classical). A2DP).
• 🔋 Energy savings – the headphone battery lasts 30% longer.
• 🔊 The ability to connect up to 4 devices at a time (in theory).

⚠️ At the time of 2026, not all headphones support LE Audio. check the specifications of your model on the manufacturer's website.

Bypassing restrictions through ADB (for advanced users)

If your Xiaomi smartphone doesn’t support Dual Audio at the software level, but is hardware capable of it (e.g., models on the Snapdragon 7).+ Gen 2, you can force the function to activate ADB. This method requires unlocking. USB-Debugging and working with the command line.

Step 1: Preparation

• 📱 Enable Developer Mode: Go to Settings → About the phone and 7 times tap on the version MIUI.
• 🔧 Back to Settings → Additionally. → For developers and activate USB-debugging.
• 💻 Install Android SDK Platform Tools on PC.

Step 2: Execution of commands

Connect your phone to your PC via USB (select File Transfer Mode) and execute:

adb devices


adb shell settings put global bluetooth_dual_audio_enabled 1




adb shell settings put global bluetooth_multi_audio_enabled 1




adb reboot

After the reboot, the Double Audio should appear in the Bluetooth settings. If it is not, try the additional command:

adb shell am start -n com.android.settings/.Settings$BluetoothSettingsActivity

Step 3: Checking

Connect two sets of headphones and play audio. If you only hear it on one device, do this:

adb shell dumpsys bluetooth_manager

In the output, find the line MultiAudioEnabled – if the value is false, then your chipset does not support the function.

💡

The ADB method only works on smartphones with Qualcomm processors. On MediaTek, it can cause Bluetooth module failures.

Typical problems and their solutions

When you connect two headphones at the same time, Xiaomi users often encounter typical errors.

If none of the methods worked, check:

• 🔄 Headphone compatibility: Some models (e.g. AirPods) block simultaneous connection to multiple sources.
• 📡 Interference: Other Bluetooth devices (such as wireless mice or keyboards) can create conflicts.
• 🔋 Headphone Charge: When the charge level is below 20%, some devices automatically turn off.

💡

If you use headphones of different brands, try to connect a newer model first - this will reduce the risk of codec conflicts.
