How to connect two Xiaomi headphones to the same phone: all ways 2026

Want to share music with a friend or use two pairs of Xiaomi headphones at the same time? It is possible - modern smartphones of the brand support simultaneous connection of several audio devices via Bluetooth. But not everyone knows how to properly configure such a circuit without loss of sound quality or synchronization.

In this article, we will discuss three working methods for connecting two headphones to the same Xiaomi phone (including the Redmi Note 12, POCO X5, Mi 11 and others), consider both standard MIUI features and workarounds for devices without Dual Audio support, and also the model compatibility table and responses to frequent errors.

Spoiler: The most reliable way to do this is even on budget smartphones with MIUI 12 and later, but there are some nuances about latency and volume levels, and that's what we'll talk about.

1.The method via Dual Audio (official function of MIUI)

Starting with MIUI 12, Xiaomi has added support for Dual Audio, which allows you to stream audio to two Bluetooth devices at once.This is the easiest method, but it doesn’t work on all models.

To activate the mode:

1. Connect the first pair of headphones through Settings → Bluetooth.
2. Open Settings → Connections and Sharing → Dual Audio
3. Turn on the switch and select the second pair of headphones from the list of available devices.

If you don't have Dual Audio on the menu, your model doesn't support the firmware level function, so move on to the following.

An important nuance: when using Dual Audio, the sound on both devices will be mono (single channel), not stereo, and there is a delay of up to 0.5 seconds between the headphones.

2.Use of the SoundAssistant application (for all models)

If your Xiaomi doesn’t support Dual Audio, use Samsung’s official SoundAssistant app (yes, it works on Xiaomi!) which allows you to connect up to 5 Bluetooth devices at a time, but requires manual tuning.

Instructions:

1. Download SoundAssistant from Google Play.
2. Connect both pairs of headphones via the standard Bluetooth menu.
3. Open SoundAssistant, go to Multisound → Select devices.
4. Check both pairs of headphones and press Start.

Advantages of the method:

• 🎧 It works on all Xiaomi models with Android 9+, including the old Redmi 9 or POCO X3.
• 🔊 It supports stereo sound (unlike Dual Audio).
• 🔄 You can adjust the volume for each device separately.

Make sure your headphones are charged (>50%)\nDisable your headphones from other devices\nEnable visibility mode on both pairs\nClose background applications using Bluetooth (e.g. fitness trackers)

-->

⚠️ Warning: When you first connect through SoundAssistant, you may experience a "Device not supported" error. Solution: Restart your phone and try again. If the problem persists, upgrade the app to the latest version.

3. bypass method via Bluetooth splitter (for older models)

If the first two methods didn’t work (e.g., Xiaomi with custom firmware or a very old version of Android), use a Bluetooth transmitter with Dual Link support. This is an external device that connects to the phone via a 3.5 mm connector or USB-C and broadcasts the sound to two pairs of headphones.

Popular models of transmitters:

How to set up:

1. Connect the transmitter to the phone through the appropriate connector.
2. Activate the pairing mode on the transmitter (usually a long press on the power button).
3. Connect both pairs of headphones to the transmitter (not to the phone!).
4. In the phone sound settings, select the transmitter as the output device.

⚠️ Note: When using a 3.5mm transmitter on phones without audio output (e.g. Xiaomi 13), you will need an adapter. USB-C → 3.5mm This can add sound delay up to 100ms.

💡

If the sound is interrupted when using the transmitter, try turning off the aptX codec in the Bluetooth headphone settings and switch to SBC or AAC.

4. Sound synchronization setting (delay elimination)

One of the main problems when connecting two headphones is the difference in playback time (one earphone can “lag behind” the other), this is due to the peculiarities of processing Bluetooth codecs.

For Dual Audio (MIUI):

• 🔄 Reconnect both devices in order: first a newer headphone model, then an older one.
• 📱 Enable Game Turbo mode in Settings → Special features (reduces system delay).

For SoundAssistant:

• ⚙️ In the application settings, disable the option Automatic Synchronization.
• 🎵 Manually adjust the delay for each device in the Menu Sound Delay (step 10 ms).

For Bluetooth transmitters:

• 🔋 Use the aptX Low Latency codec (if supported by headphones).
• 📶 Reduce the distance between the phone and the transmitter (optimally, up to 1 meter).

💡

Minimal latency is achieved when using headphones with support for aptX Adaptive or LC3 (for example, Xiaomi Buds 4 Pro or Redmi Buds 5 Pro).

5. Frequent errors and their solutions

Even if you set it up properly, you can have problems, and here are the most common scenarios and ways to fix them:

Problem 1: The second device is connected, but there is no sound.

• 🔄 Reboot both headphones (on most Xiaomi models, this is done by holding the touch button for 10 seconds).
• 📱 In Bluetooth phone settings, forget both devices and connect again.
• 🔊 Check if Monopoly Sound is activated in the app settings (e.g. Spotify or YouTube).

Problem 2: The sound is interrupted or jammed.

• 📶 Make sure there are no interference sources nearby (Wi-Fi routers, microwaves).
• 🔋 The charge of headphones should be above 30% (at a low charge, energy saving can work).
• 📱 Enable High Performance Mode in Battery Settings for SoundAssistant App.

Problem 3: The microphone on the headphones is not working.

• 🎤 In Call Settings (Settings) → Annexes → Phone. → Calls) Select the main device for the microphone.
• 🔄 If you use SoundAssistant, turn off the Multi-Microphone option.

Headphone compatibility: which models work together

Not all Xiaomi headphones can be connected at the same time, but here are the key compatibility rules:

They work well together:

• 🎧 Xiaomi Buds 4 Pro + Redmi Buds 5 Pro (the same chip Qualcomm) QCC5151).
• 🎧 Mi True Wireless Earphones 3 + Mi AirDots 3 Pro (support) LC3).
• 🎧 Any headphones on a Qualcomm chip QCC3040 newer.

Problems are possible with:

• 🚫 Redmi AirDots (1st generation) – outdated chip Realtek RTL8763B.
• 🚫 Mi Basic Earphones (wired with Bluetooth adapter) – unstable connection.
• 🚫 Headphones of different brands (for example, Xiaomi) + Sony – Codec Conflicts Possible.

⚠️ Note: If you connect headphones Xiaomi and another brand in SoundAssistant forcibly select the codec SBC This will reduce the likelihood of a connection breaking.

7. Alternative solutions (if nothing has worked)

If none of these methods worked, consider these options:

Method 1: Using a Y-spunter for wired headphones

• 🎵 Suitable for models with 3.5 mm connector (for example, POCO X3 Pro).
• 🔌 We need an adapter. USB-C → 3.5 mm for telephones without audio output.
• ⚠️ Cons: the sound will be mono if the headphones do not support collaboration.

Method 2: Sound transmission over Wi-Fi (SoundWire application)

• 📶 Requires the connection of the phone and a second device (for example, a laptop) to the same network.
• 🎧 Second headphones are connected to the laptop via Bluetooth.
• ⏱️ The delay in sound can reach 1-2 seconds.

Method 3: Separate sound through Smart TV

• 📺 Connect your phone to a Xiaomi TV HDMI ARC Bluetooth.
• 🔊 On the TV, activate the audio output to two Bluetooth devices (if supported).
• 🎮 It is suitable for watching movies, but not for music (delay) ~200 ms).
