How to connect two headphones Xiaomi at the same time: instructions for all models

Connecting two pairs of wireless headphones to one Xiaomi smartphone is a useful feature that allows you to share sound with another, use different devices for music and calls, or create a stereo effect with two speakers. However, not all users know that this feature is not available on all models and requires the right setup. In this article, we will discuss how to activate Dual Audio (or Dual Headphones) on Xiaomi, Redmi and POCO smartphones, what limitations exist and how to circumvent typical errors.

It's important to understand that the dual headphone function depends on the MIUI version, the phone model, and the type of headphones. For example, Xiaomi Buds 3 Pro and Redmi Buds 4 Active support this mode, but it will require you to turn on hidden settings or update the firmware. If you tried to connect the second pair of headphones through the standard Bluetooth menu, but it didn't work out, don't get upset. Most of the time, the problem is solved in 5 minutes.

What Xiaomi models support the connection of two headphones

Dual Audio is not available on all Xiaomi devices, but depends on the MIUI version (starting with MIUI 12) and the hardware platform.

• 📱 Smartphones: All models on MIUI 12/13/14 Snapdragon chipset 8xx or Dimensity 1xxx (for example, Xiaomi 12/13/14 series, Redmi K50/K60, POCO F4/F5). Budget models (e.g. Redmi Note) 11) may not support the function.
• 🎧 Headphones: only Xiaomi/Redmi Buds with Bluetooth support 5.0+ profile A2DP. Headphones from other brands (such as Sony) WH-1000XM5) It will be connected, but the sound will be duplicated on only one device.
• 🔄 Firmware: On custom firmware (e.g. Pixel Experience), the function may not work stable or be available.

If your Released smartphone is up to 2020 (like the Xiaomi Mi 9 or Redmi Note 8 Pro), it’s likely that Dual Audio mode is not available at the system level, and you can try the workarounds we’ll talk about below.

Step-by-step: how to turn on two headphones on Xiaomi

If your device supports the feature, follow this instruction, and we'll look at two ways: through standard MIUI settings and through a hidden developer menu.

Method 1: Through Bluetooth settings (for MIUI 13/14)

This is the easiest method that works on most modern Xiaomi smartphones:

1. Open Settings → Bluetooth and connect the first pair of headphones (for example, Xiaomi Buds 4).
2. Include the second pair of headphones in the pairing mode (usually you need to press the button on the case or open the case cover).
3. Return to the Bluetooth menu and tap three points (⋮) In the upper right corner, select Dual Audio).
4. Activate the switch and select the second pair of headphones from the list of available devices.

If you don't have dual audio, your model doesn't support the firmware level function.

Method 2: Developer menu (for MIUI 12-14)

This method is suitable for devices where the function is hidden but technically supported.

1. Go to Settings → About Phone and tap 7 times on the MIUI Version until the notification “You became a developer” appears.
2. Return to the main settings menu and open Additional settings → Developer settings.
3. Find the option to Enable Dual Headset (or Enable Dual Audio) and activate it.
4. Reboot your smartphone and try connecting two devices via Bluetooth.

If you don’t have an option, your device doesn’t support the feature at the software level, in which case you can try third-party apps (more on this below).

Check the MIUI version (should be 12 or later)

Make sure both pairs of headphones are charged

Enable pairing mode on both devices

Activate the developer menu (if required)-->

Compatibility table for Xiaomi headphones with Dual Audio mode

Not all Xiaomi wireless headphones can work in pairs, and the following is a table of compatibility of popular models:

If your model is not in the table, test it experimentally, and consider that when you connect two pairs of headphones, the sound quality can decrease due to Bluetooth bandwidth limitations.

What to do if two headphones are not connected

If you followed the instructions, but the Xiaomi smartphone refuses to connect the second pair of headphones, try the following solutions:

• 🔄 Reboot the Bluetooth module: Turn off Bluetooth for 30 seconds, then turn on again and repeat pairing.
• 📱 Reset your network settings: go to Settings → Connections → Resetting Wi-Fi, Mobile Network and Bluetooth.
• 🔧 Update the firmware: check for updates in Settings → The phone. → Updating the system.
• 🎧 Check the headphones: make sure both pairs support Bluetooth 5.0+ and are in a conjugation mode.

⚠️ Note: On some models (e.g, POCO X3 Pro Dual Audio only works with Xiaomi headphones. Headphones from other brands (e.g., Xiaomi, JBL Samsung or Samsung may be connected, but the sound will be duplicated on only one device.

If nothing helps, try using third-party apps like SoundAssistant or Dual Audio (available on Google Play).These emulate Dual Audio mode but can cause audio delays.

How to use two headphones for different purposes

Xiaomi's Dual Audio mode allows you to not only duplicate the sound, but also distribute it across different devices.

• 🎵 Music on one headphones, calls on others: in Bluetooth settings, you can assign a priority device for calls.
• 🎮 Gaming sound and voice chat: connect the headphones to the PC, and the second pair to the smartphone for Discord.
• 🔊 Stereo effect: place two pairs of headphones in different corners of the room to create surround sound.

To adjust the sound distribution:

1. Put both pairs of headphones on.
2. Open Settings → Sound → Additional settings.
3. Select the default output device for calls and media.

⚠️ Attention: When two Bluetooth devices are connected at the same time, audio latency can increase, especially in games or when watching videos. To reduce latency, turn off Absolute Volume in the developer settings.

Alternative ways to connect two headphones

If your Xiaomi smartphone does not support Dual Audio, you can use the workarounds:

1.Use of Bluetooth transmitter

Get a Bluetooth transmitter (like the Avantek APTX or 1Mii B06 Plus) that connects to a 3.5mm or USB-C audio output and streams audio to two devices simultaneously.This solution is suitable for older Xiaomi models (like the Mi A2 or Redmi 5 Plus).

Applications for sound duplication

Install one of the following applications:

• 🔊 SoundAssistant (from Samsung, but runs on Xiaomi) – allows you to choose multiple output devices.
• 🎧 Dual Audio – a specialized application for simultaneous connection of two headphones.
• 🔄 Bluetooth Auto Connect – Automating the Connection of Multiple Devices.

Please note that third-party applications may:

• 🛑 Slow down the system.
• 🔊 Increase the delay of sound.
• 🔋 Quickly discharge the battery.

3. Connection via AUX-split

If you have headphones with wire, use a 3.5mm splitter (like the Belkin RockStar) which doesn’t require Bluetooth and works on any device, but is only suitable for wired headphones.

💡

If you use two headphones to watch movies often, turn on Low Latency in your Bluetooth settings, which will reduce the desynchronization of audio and video.
