How to connect two Xiaomi headphones to one smartphone: the complete guide

Can I connect two Xiaomi headphones at the same time?

Owners of Xiaomi wireless headphones often face the question: is it possible to use two devices to listen to music or watch movies from the same smartphone? The answer is yes, but with reservations. Dual Audio technology (or Dual Bluetooth) allows you to synchronize two audio devices, but not all Xiaomi models support this feature out of the box.

The main problem is the limitations of the Bluetooth protocol: the standard version 4.2 And the one below is physically unable to transmit sound to two devices at the same time. 5.0+ and update MIUI 12 And the new situation has changed. Now many smartphones. Xiaomi/Redmi/Poco can broadcast audio to two headphones, but with nuances: possible sound delays, reduced quality or restrictions on the models of headphones.

In this article, we’ll look at 5 proven ways to connect two Xiaomi headphones, from standard MIUI settings to third-party workarounds, and learn which headphones and smartphones are compatible, and how to avoid typical synchronization issues.

Method 1: Built-in Dual Audio in MIUI (for Bluetooth 5.0+)

Starting with MIUI 12, Xiaomi has added Dual Audio support for smartphones with Bluetooth 5.0 and later, which allows you to connect two audio devices at once, but does not work with all headphones. Here's how to activate it:

1. Open Settings → Connections and Sharing → Bluetooth.
2. Connect the first headphone (for example, Xiaomi AirDots 3 Pro).
3. Click on the three dots in the upper right corner and select Dual Audio.
4. Activate the slider and connect the second headphone.

Important: the feature may not be available on budget models (Redmi 9A, Poco M3) or smartphones older than 2019, and both headphones must support the A2DP protocol (most Xiaomi models support it).

⚠️ Note: Dual Audio can delay up to 200ms between headphones, which is critical for gaming or watching videos, but not noticeable when listening to music.

Method 2: SoundAssistant (for all versions of MIUI)

If your smartphone doesn’t have Dual Audio built-in, use Samsung’s official SoundAssistant app (yes, it works on Xiaomi!) which is suitable for Bluetooth 4.2+ devices and allows you to sync two headphones with minimal latency.

Instructions:

1. Download SoundAssistant from Google Play.
2. Connect both headphones to the smartphone separately.
3. Open the app and go to Additional Features → Double audio.
4. Select both headphones from the list and activate synchronization.

The advantage of this method is that it supports even older headphone models (Redmi AirDots S, Mi True Wireless Earphones Basic), but the sound will be mono, not stereo, if the headphones do not support dual mode.

Method 3: Use of Bluetooth splitter (for any model)

If the software methods don’t work, try a hardware solution called a Bluetooth splitter (like the Avantek BTA-200 or 1Mii B06 Plus) that connects to your smartphone like a regular headphone and then relays the signal to two other audio devices.

Pros of the method:

• 🔹 It works with all Xiaomi headphone models, including the old AirDots 1.
• 🔹 No sound delays (if the splitter supports aptX Low Latency).
• 🔹 You can connect headphones of different brands.

Cons:

• 💰 Additional costs (the splitter costs from 1,500) ₽).
• 🔋 Increased battery consumption of the smartphone.

⚠️ Attention: Cheap splitters (up to 1,000) ₽) often have problems with synchronizing sound. Before buying, check reviews on AliExpress or Yandex Market for "model name" + delay".

Method 4: Connect via computer (for gamers and streamers)

If you need to connect two Xiaomi headphones for gaming or streaming, use a PC/laptop as an intermediary.This method is suitable for owners of Xiaomi Buds 3 Pro or AirDots 3, as it allows you to adjust the audio delay manually.

Instructions for Windows 10/11:

1. Connect both headphones to the PC via Bluetooth.
2. Open the settings → System → Sound.
3. In the Output section, select both devices (hold Ctrl for multiple selection).
4. Install the VB-Cable app to synchronize audio streams.

For macOS:

• Use the Audio MIDI Setup (built into the system).
• Create a Multi-Exit Device and add both headphones.

💡

For PC games, use Steam Link or Moonlight to stream audio from PC to smartphone, and then connect the headphones to your phone. This will reduce latency to 30-50 ms.

Method 5: A workaround through the LocalCast application (for multimedia)

If you need to sync two headphones just to watch videos or listen to music, LocalCast will help you bypass the limitations of MIUI. It allows you to output sound to multiple Bluetooth devices at once.

How to set up:

1. Download LocalCast.
2. Open the video/audio file in the app.
3. Click on the Bluetooth icon and select both headphones.
4. Activate the option to sync audio.

Limitations:

• 🎵 It only works with local files (does not support streaming services).
• 🔊 Possible artifacts of sound at high bitrate.

Compatibility table: Which Xiaomi headphones support dual-audio?
