How to connect two Xiaomi headphones to the same phone: the complete guide

Can I connect two Xiaomi headphones at the same time?

Owners of Xiaomi wireless headphones often face the question: how to use two devices at the same time with the same smartphone? This is relevant for couples when you want to listen to music together, or for users who have headphones of different models. Fortunately, modern Bluetooth chips in Xiaomi smartphones (especially on Snapdragon 8xx and Dimensity processors) support Dual Audio or Multipoint technology, which allows you to broadcast audio to two devices at the same time.

However, not all headphones and smartphones work equally well in this mode. For example, Xiaomi AirDots 2 and Redmi Buds 3 Pro support synchronous connection, but the budget Redmi Buds 3 Lite can refuse to work in tandem with another device. In this article, we will discuss all the working ways to connect two Xiaomi headphones to the same phone, including hidden MIUI settings and third-party applications.

It’s important to understand that connection stability depends on the Bluetooth version (5.0 or higher), the distance between devices, and even the firmware of your smartphone. If you’re using custom firmware or an outdated version of MIUI, some features may not be available.

Method 1: Use the Dual Audio function in MIUI

Since MIUI 12, Xiaomi has built-in Dual Audio, which allows audio to be transmitted to two Bluetooth devices simultaneously, a method that works on most flagships and mid-budget models, such as the Xiaomi 11/12/13 series, Redmi Note 10/11 Pro and later.

To activate Dual Audio, follow the following steps:

• 📱 Open the Settings. → Connections and sharing → Bluetooth.
• 🔗 Connect the first headphone (for example, Xiaomi Buds 4 Pro).
• 🎧 Click on the gear icon next to the headphone name and select Additional settings.
• 🔊 Enable the option of Dual Audio (could be called dual audio or multimedia on two devices).
• 🔄 Connect the second headphone through standard pairing.

If the Dual Audio option is missing, your smartphone model or MIUI version doesn’t support it, in which case try updating your firmware or using alternative methods in the following sections.

⚠️ Note: Dual Audio may cause a slight delay in sound (up to the end of the day). 100-200 This is due to the specifics of data transmission over Bluetooth.

Method 2: SoundAssistant application (for older versions of MIUI)

If your smartphone is running MIUI 11 or older, there may not be a built-in Dual Audio feature, which Samsung’s third-party SoundAssistant app, which works amazingly on Xiaomi devices, will help, allowing you to direct sound to two Bluetooth devices at the same time, even if the smartphone doesn’t officially support this feature.

Instructions for setting:

1. Download SoundAssistant from Google Play.
2. Connect both headphones to your phone via Bluetooth.
3. Open the app and go to the Dual Audio section.
4. Select both connected devices and activate synchronization.

The app supports most Xiaomi headphone models, including AirDots, Buds and FlipBuds. However, some firmware may require permission to change system settings (via ADB).

Method 3: Using a Bluetooth splitter

If software methods are not working or causing delays, you can use a hardware solution called a Bluetooth splitter. This small device (such as the Avantek BTA-200 or 1Mii B06 Plus) connects to the phone via Bluetooth and then relays the signal to two pairs of headphones at the same time.

Advantages of this method:

• 🎵 No sound delays between headphones.
• 🔋 Low power consumption (the splitter runs on its own battery).
• 📱 Compatible with any headphone models, including wired ones with Bluetooth adapter.

Disadvantages:

• 💰 Additional costs (from 1500 to 4000 rubles).
• 🎒 You need to carry another device with you.

⚠️ Attention: Cheap Bluetooth splitters (up to 1000) ₽) They often have problems with sound synchronization and poor transmission quality. AAC minimum delay.

Method 4: Connect via AmpMe (for music)

If you only need to sync the sound to listen to music, you can use the AmpMe app, which allows you to create "audio parties" where multiple devices play the same track at the same time, and each participant can adjust the volume on their headphones.

How it works:

1. Install AmpMe on both smartphones (if the second headphone is connected to another phone).
2. Create or join an existing party.
3. Select the source of the music (Spotify, YouTube, local files).
4. Press Play – the sound will be synced across all devices.

This method is suitable for joint playlist listening, but is not suitable for games or videos due to possible out-of-synchronizations. Also consider that both smartphones must be connected to the same Wi-Fi network or mobile Internet.

💡

For better sync in AmpMe, turn off the energy-saving mode on both smartphones and use headphones with AAC or aptX support.

Method 5: Manual connection through developer settings

For power users, there is a way to activate the hidden feature of multithreaded audio through the developer settings, a method that doesn’t work on all devices, but can help if other methods don’t work.

Instructions:

1. Activate Developer Mode by tapping 7 times on the MIUI Version in Settings → About Phone.
2. Go to Settings → Additional → For developers.
3. Find the option Disable Absolute Volume (Bluetooth) and turn it off.
4. Then find Max. the number of connected audio devices and set the value of 2.
5. Reboot your smartphone and try connecting both headphones.

If Max connected audio devices are not available, your smartphone model does not support this feature at the software level, in which case you only need to use hardware solutions (forklift) or third-party applications.

💡

Changing the developer settings can cause Bluetooth to work unstable. If the headphones stop connecting after experiments, reset the network settings (Settings → Connections → Reset the settings of Wi-Fi, mobile network and Bluetooth).

Frequent problems and their solutions

When connecting two Xiaomi headphones to the same phone, users often encounter common errors, and here are the most common ones and ways to fix them:

• 🔌 One earbud doesn't connect: Make sure both devices are at least 20% discharged (some models refuse to connect when low charge).
• 🎵 The sound goes only to one headphone: In Bluetooth settings, click on the gear icon next to the headphone and select Stereo (not Mono or Phone).
• 🔊 Latency between headphones: Try turning off the absolute Bluetooth volume in the developer settings or use headphones with support for aptX Low Latency.
• 📱 Smartphone 'forgets' second headphone: This could be due to energy savings. add Bluetooth app to battery optimization exception list (Settings) → Battery → Optimizing the battery).

If neither of these methods worked, check your headphones are compatible with Multipoint. For example, Xiaomi Buds 3T Pro and FlipBuds Pro officially support connecting to two devices at once, but do not always work correctly in the “two headphones, one phone” mode.
