Connecting two Xiaomi Mi True headphones to one device: the full guide

Trying to connect two pairs of Xiaomi Mi True wireless headphones to a single smartphone or computer is a challenge many users face. Według statistics, about 30% of owners of such headsets want to use them simultaneously to share music, games or watch movies. However, standard Android/iOS settings do not always allow you to do it out of the box.

In this article, we will discuss all the working ways to synchronize two pairs of Mi True Wireless Earphones (including the Basic 2, TWS 2 and Air 2 models) with a single sound source. You will learn what limitations the Bluetooth protocol imposes, how to circumvent them using Xiaomi proprietary features and third-party applications, and what nuances are important to consider for stable operation.

Why the standard connection is not working

The main problem lies in the architecture of the Bluetooth Classic protocol (before version 5.0), traditionally one source device (smartphone, PC) can only transmit audio stream to one headset at a time.

• 🔹 Profile A2DP — It is responsible for stereo sound transmission, but does not support multi-connection in older versions.
• 🔹 Channel bandwidth – dual channel data transfer requires a larger bandwidth, which is not provided for Bluetooth 4.2 and below.
• 🔹 Hardware limitations of the chipset – budget smartphones (for example, Redmi) 9A) They are not physically able to process two audio streams.

That changed with the introduction of Bluetooth 5.2 and Dual Audio (or Dual Pairing), which Xiaomi introduced into flagship models starting with the Mi 10 and Redmi K30 Pro. However, even here there is a nuance: not all Mi True headphones support this mode. For example, Mi True Wireless Earphones Basic (2019) is not compatible with Dual Audio, unlike Mi True Wireless Earphones 2.

⚠️ Note: If your smartphone Released before 2020, the probability of support for Dual Audio tends to zero.

Method 1: Dual Audio (Bluetooth 5.2+)

This is the most reliable method, but it only works if three conditions are met:

1. Your smartphone supports Bluetooth 5.2 (see the list of models below).
2. Both pairs of headphones are Xiaomi Mi True Wireless Earphones 2 or later (with support for LE Audio).
3. The firmware is updated to the latest version (for MIUI 13+).

Instructions for connection:

1. Open Settings → Bluetooth and connect the first pair of headphones.
2. Click on the gear icon next to the headset name and select Dual Audio.
3. Activate the search mode on the second pair of Mi True (press the button on the case for 5 seconds) and select it from the list of available devices.

If you don't have Dual Audio in your settings, your smartphone model doesn't support this feature, so go to alternatives.

Method 2: Applications for sharing audio stream

If you don't have Dual Audio hardware, you can use third-party apps, which are basically a virtual audio device that duplicates the sound into two headsets.

• 🎧 SoundAssistant (from Samsung, but runs on Xiaomi) – allows you to direct sound to two Bluetooth devices at the same time.
• 🎧 Bose Connect – Although designed for Bose headphones, some Mi True users note its performance.
• 🎧 Bluetooth Dual Audio – a dedicated stream sharing app (requires root rights on older versions of Android).

Instructions for SoundAssistant:

1. Install the app from Google Play.
2. Connect both pairs of Mi True headphones separately.
3. Open SoundAssistant and go to Settings → Double audio.
4. Select both headsets in the list and activate the mode.

⚠️ Note: When using third-party applications, audio delays up to 200 ms are possible. This is critical for watching videos - synchronize the sound manually in the player.

Update the headphone firmware through Mi Home

Disable power saving for Bluetooth in Android settings

Close background apps that use audio (Spotify, YouTube)

Check the battery charge of headphones (minimum 50%)

Method 3: Connecting via Windows 10/11

On a PC with Windows 10 (version 2004+) or Windows 11, you can connect two pairs of Mi True without additional software, but with restrictions:

• 🖥️ The sound will be duplicated, not divided into stereo channels.
• 🖥️ There may be interference with a weak Bluetooth adapter (external, such as TP-Link, is recommended). UB500).

Step-by-step:

1. Open Settings → Devices → Bluetooth and connect the first pair of headphones.
2. Return to the Sound Settings (Win + I → System → Sound) and select the connected Mi True as the default output device.
3. Connect the second pair of headphones and in the same menu select Additional settings of the device.
4. Set a tick to Allow applications to independently manage this device.
5. In the sound control panel (right click on the speaker icon → Open sound parameters → Properties), select 16-bit, 44100 Hz format for both headsets.

To synchronize the sound between two pairs, use the VLC player:

1. Open the video/audio file in VLC.
2. Go to Audio → Audio → Output device and select both Mi True pairs.
3. If necessary, adjust the delay in Tools → Effects and filters → Synchronization.

💡

If the sound is interrupted, reduce the Bluetooth bitrate in the adapter settings. Open Device Manager → Bluetooth Adapters → Properties → Additional and set the Bluetooth Audio Quality setting to Optimize for Quality (if available).

Method 4: Using a Bluetooth transmitter

If software methods don't work, you can use an external Bluetooth transmitter that supports multi-connection, such as the 1Mii B06 Plus or Avantek APTX models that allow you to connect up to two pairs of headphones at once.

• 🔊 No dependence on the smartphone or PC model.
• 🔊 Codecs are supported APTX and AAC, sound-enhancing.
• 🔊 Minimum latency (up to 40ms) which is important for gaming.

Instructions for setting:

1. Connect the transmitter to a sound source (e.g., TV or PC audio output via 3.5mm jack or USB-C).
2. Activate the pairing mode on the transmitter (usually a long press on the power button).
3. Alternately connect both Mi True pairs, following the instructions of the voice assistant transmitter.
4. In the transmitter settings (if there is a screen), select Dual Link mode.

The cost of such devices starts from 2,500 rubles, but they guarantee the stability of the connection even at a distance of up to 20 meters.

Common Problems and Their Solutions

When connecting two pairs of Xiaomi Mi True users often encounter common errors.

If the Mi True headphones are not defined by the device at all, reset the settings:

1. Place both headsets in the case and close the lid.
2. Press and hold the button on the case case case for 15 seconds (the indicator flashes red).
3. Remove the headphones and re-activate the mating mode.

Compatibility with other devices

Apple owners often wonder if two pairs of Xiaomi Mi True can be connected to an iPhone or MacBook. Unfortunately, iOS does not support multi-connection Bluetooth headphones at the software level.

• 🍎 Use Audio. MIDI Setup on Mac to create an aggregated device (MacOS 11 required)+).
• 🍎 Connect headphones via Bluetooth transmitter (as in Method 4).
• 🍎 Apply applications like Airfoil (paid, $29), which broadcasts sound to multiple devices.

For Android-TV (such as Mi Box S) and Smart-TV, the situation is similar:

• 📺 Xiaomi. TV s MIUI TV 3.0+ Dual Audio mode available in Bluetooth settings.
• 📺 On TVs of other brands (Samsung, LG) You will need an external transmitter.

Important: When connecting to game consoles (PlayStation, Xbox), two pairs of Mi True cannot be used - these devices support only one Bluetooth audio device.

💡

The most versatile way is a Bluetooth transmitter, which works with all devices (including iPhones and TVs), requires no root rights, and provides minimal audio latency.
