How to turn on two headphones Xiaomi at the same time: all the ways and nuances

Using two pairs of Xiaomi wireless headphones at once is not only convenient for sharing music or watching movies, but also a useful feature for gamers who want to sync the sound with a friend. However, not all users know that this option even exists, and those who have tried often face connection errors or unstable work. In this article, we will discuss all the available ways to connect two headphones to the same sound source, including official and alternative methods.

It is important to understand that the simultaneous connection function depends on the headphone model, the version of the MIUI firmware on the smartphone, and even the type of sound source (smartphone, tablet, PC). For example, Xiaomi AirDots Pro 2 and Redmi Buds 4 Pro support Dual Audio technology, but its implementation may differ. We tested all methods on current devices and collected step-by-step instructions for typical errors.

Which Xiaomi models support two headphones simultaneously?

Not all Xiaomi wireless headphones can work in tandem with another model, but here are the key compatibility criteria:

• 🔹 AirDots Pro Series (starting with AirDots Pro 2) – support Dual Audio through proprietary software.
• 🔹 Redmi Buds 3/4 Pro – have a built-in synchronization function with other headphones of the same model.
• 🔹 Xiaomi FlipBuds Pro – require firmware updates to MIUI 12.5+.
• 🔹 Budget models (e.g. Redmi Buds 2 Lite) – do not support simultaneous hardware connection.

If your model is not on this list, don’t be too upset: there are workarounds through third-party apps or operating system-level Bluetooth settings, but stability is not guaranteed.

Official method: Dual Audio function in MIUI

The most reliable method is to use the built-in Dual Audio feature (or Dual Audio in the Russian version of MIUI), which is available on Xiaomi, Redmi and POCO smartphones with MIUI 12 firmware and later.

1. Connect the first pair of headphones to your smartphone via Settings → Bluetooth.
2. Open the notification bar and hold the Bluetooth icon to go to advanced settings.
3. Slip on the connected headphones and select Dual Audio (or Dual Audio).
4. Turn on the second pair of headphones in pairing mode (usually hold the power button for 5-7 seconds).
5. Select the second pair in the list of available devices.

Once connected successfully, the sound will be duplicated on both devices, but there are nuances:

• 🎧 The delay of sound between headphones can reach 50-100 ms.
• 🔋 Fast battery discharge – both earbuds consume energy at the same time.
• 📱 In some models (for example, POCO X3 Pro) the function may not work smoothly.

Alternative methods for unaccompanied models

If your headphones don’t support Dual Audio, you can try the following workarounds:

1. Sound separation applications

There are third-party utilities that emulate the dual audio function at the OS level.

• 📱 SoundAssistant (for Samsung, but it works on Xiaomi with Android 10)+).
• 🎵 Bose Connect (supports some Xiaomi models via shared protocol).
• 🔊 AmpMe – synchronizes sound over a local network (suitable for watching video).

Example of settings through SoundAssistant:

1. Install the app from Google Play.


2. Go to Settings → Additional → Double audio.




3. Select both connected earphones.




4. Activate the option "Sync delay".

💡

If the sound in the headphones is not synchronized, try manually setting the delay in the application settings (usually 30-70 ms is enough).

2.Use of Bluetooth transmitter

For devices without Dual Audio support (e.g. Redmi Buds 2), you can use an external Bluetooth transmitter with multipoint function, for example:

• 📡 Avantek BTA-200 (Supports 2 devices simultaneously).
• 🎧 1Mii B06 Pro (low latency, aptX) LL).

Connection diagram:

1. Connect the transmitter to the sound source (TV, PC, smartphone) via 3.5 mm or USB-C.
2. Activate the multipoint mode on the transmitter (usually a long press on the power button).
3. Connect both pairs of headphones to the transmitter.

Synchronization of two headphones Xiaomi with a computer (Windows/macOS)

On a Windows 10/11 or macOS PC, you can also connect two wireless headphones at the same time, but you will need additional setup.

For Windows:

1. Open the settings → Devices → Bluetooth.
2. Put the first pair of headphones on.
3. Press Win + R, enter ms-settings:appsfeatures and press Enter.
4. Find Stereo Mix (if not, turn it on through Control Panel → Sound → Record).
5. In the audio settings, select both output devices.

For macOS:

On the Mac, the function is called the Audio MIDI Setup.

1. Open Applications → Utilities → Audio MIDI Setup
2. Click + → Create a device with multiple outputs.
3. Select both pairs of headphones in the list.
4. In the system sound settings, select the created device.

Note: Windows can have a noticeable delay between headphones (up to 200 ms), and macOS sound syncs better, but requires support for AAC or aptX codecs.

Common Problems and Their Solutions

When connecting two headphones, users often encounter common errors, and we have collected the most common ones and ways to fix them:

⚠️ Warning: If the first one turns off after connecting the second headphone, check Bluetooth power saving settings in Settings → Battery → Optimization: Some Xiaomi models aggressively disable "inactive" devices.

How to check the synchronization of sound between headphones?

To make sure that the sound in both headphones is played synchronously, follow the following steps:

1. Turn on a track with a clear bit (such as a metronome or a drum solo).
2. Listen to the sound alternately in each earpiece, closing the second.
3. If you notice a delay, try:

• 🔄 Reconnect the headphones.
• 📱 Reset the sound source.
• 🎛️ Change the Bluetooth codec in the developer settings (Settings) → The phone. → Version. MIUI → 7 times to tap).

For accurate verification, you can use applications like SoundAnalyser (Android) or AudioTools (iOS), which measure latency in milliseconds.

💡

If the delay exceeds 100 ms, synchronous viewing of the video will be impossible - the sound will "float" relative to the picture.
