Connect two headphones Xiaomi Mi True Wireless to the same phone: the full guide

Xiaomi Mi True Wireless headphones have become a popular choice thanks to a combination of sound quality, convenience and affordable price. However, many users are faced with the question: can you connect two sets of headphones to one smartphone at once? The answer is yes, but with nuances. This feature is useful for sharing music, watching movies or playing games in the company.

In this article, we will discuss all the ways to synchronize two Mi True Wireless pairs, including official methods from Xiaomi and workaround solutions. You will learn which models support this feature out of the box and which will require additional software.

Before we start, it’s important to clarify that not all Mi True Wireless headphones work equally well in paired mode. For example, Mi True Wireless Earbuds Basic 2 and Mi True Wireless Earphones 2 have limitations, while Mi Air 2 Pro or Mi AirDots 3 support Dual Audio at the firmware level. If your model is not on the list of compatible, don’t worry: there are alternative ways to use third-party apps.

Also note that when you connect two pairs of headphones, you may experience latency or reduced communication quality, due to the limitations of Bluetooth 5.0/5.2, which is used in most Xiaomi models, and we will explain how to minimize these effects.

Xiaomi Mi True Wireless models support dual connectivity

Not all Xiaomi wireless headphones can work in tandem with another set, here is the official list of models that support Dual Audio (simultaneously connecting two devices to the same source):

  • 🎧 Xiaomi Mi Air 2 Pro – full support via MIUI or the Mi Earphones app.
  • 🎧 Xiaomi Mi AirDots 3 / Mi AirDots 3 Pro – requires a firmware update to version 1.4.0.3 or later.
  • 🎧 Xiaomi Mi True Wireless Earphones 3 – Support via Bluetooth Settings β†’ More
  • 🎧 Redmi AirDots 3 is limited support (only with MIUI 12.5+ devices).

Mi True Wireless Earbuds Basic 2, Mi AirDots 2 and older versions do not support dual connection at the firmware level.

To check the firmware version of your headphones, open the Mi Earphones app (available for Android and iOS) and go to About β†’ Firmware. If your version is outdated, update it through the same app.

Method 1: Connect via Bluetooth settings (official method)

If your headphone model supports Dual Audio, follow this instruction.The method works on Xiaomi, Redmi and POCO smartphones with MIUI 12 firmware and later, as well as on some devices from other brands (for example, Samsung with One UI).

Step-by-step:

  1. Turn on Bluetooth on your smartphone and connect the first pair of Mi True Wireless headphones.
  2. Open Settings β†’ Bluetooth.
  3. Click on the icon. βš™οΈ near the connected headphones.
  4. Select Double Audio (or Dual Audio in English).
  5. Turn on the second pair of headphones in pairing mode (press the button on the body for 3-5 seconds until the indicator starts flashing white / blue).
  6. In the list of available devices, select the second pair and confirm the connection.

Once successfully connected, the sound will be broadcast to both sets of headphones simultaneously, and note that this mode may have a slight delay (up to 100-150 ms), especially when watching videos.

Update your headphones to the latest version

Charge both sets of headphones to 100%

Make sure your smartphone supports Bluetooth 5.0+

Disable other Bluetooth devices (fitness bracelets, smart watches)

⚠️ Warning: Some Mi True Wireless models turn off the noise reduction function (ANC) when dual-connected.

Method 2: Use the SoundAssistant application (for unaccompanied models)

If your headphones don’t support Dual Audio at the firmware level, you can use a third-party SoundAssistant app (available for Android) that allows you to duplicate the sound across multiple Bluetooth devices, even if it’s not provided by the manufacturer.

How to set up:

  1. Download and install SoundAssistant from Google Play.
  2. Connect the first pair of Mi True Wireless headphones through standard Bluetooth settings.
  3. Open SoundAssistant and go to Additional Settings β†’ Double Audio.
  4. Enable the second pair of headphones in pairing mode and connect it through the application.
  5. Activate the audio synchronization option to minimize latency.

The app supports volume control for each device separately, which is convenient if your headphones have different sensitivity. However, note that SoundAssistant can consume an additional battery of the smartphone (up to 5-10% per hour of active use).

For iPhone owners, there is no similar solution - Apple limits the possibility of dual connection at the iOS level, in which case only the purchase of headphones with support for Audio Sharing (for example, AirPods) will help.

πŸ’‘

If the audio in the headphones is not synchronized, try SoundAssistant to disable the option "Hardware acceleration audio." This can reduce latency, but slightly increase the load on the processor.

Method 3: Connecting via Bluetooth transmitter (universal method)

If none of the previous methods worked, you can use an external Bluetooth transmitter with Dual Link support. This device connects to the sound source (smartphone, TV, PC) and broadcasts the signal to two sets of headphones at the same time.

Equipment required:

  • πŸ“± Bluetooth transmitter with Dual Link support (e.g. 1Mii B06 Plus or Avantek APT-X).

Instructions for setting:

  1. Connect the Bluetooth transmitter to a sound source (e.g., the 3.5mm audio output of a smartphone or TV).
  2. Turn the transmitter into pairing mode (usually the Power button is held until the indicator flashes).
  3. Connect the first pair of Mi True Wireless headphones to the transmitter.
  4. Activate Dual Link mode on the transmitter (instructions vary by model, usually double-pressing the button).
  5. Put the second pair of headphones on.

The advantage of this method is minimal sound latency (up to 40 ms), since the transmitter is optimized for synchronous transmission, and the disadvantage is the additional cost of equipment (from 1500 β‚½ for a quality transmitter).

Solving problems with dual connection

Even if you've done everything right, you can have difficulties, and here are the most common problems and ways to fix them:

1.One of the headphones is not connected

  • πŸ”„ Reboot both sets of headphones (put them in the case for 10 seconds, then pull them out).
  • πŸ“± Remove the headphones from the list of conjugated devices in Bluetooth Settings and reconnect.
  • πŸ”‹ Check battery power – if the level is below 20%, the headphones may not work consistently in pair mode.

2.The sound is interrupted or delayed

  • πŸ“Ά Make sure there are no obstacles between the smartphone and the headphones (walls, metal objects).
  • 🎡 In Bluetooth settings, turn off the Audio Codec AAC and select SBC (less high quality but stable).
  • πŸ”„ Reboot your smartphone β€” sometimes resetting your Bluetooth module helps.

3.The sound is only in one headphone (mono)

  • 🎧 Check if the Mono mode is activated in the headphone settings (via the Mi Earphones app).
  • πŸ”Š In the smartphone settings, turn off Absolute Volume.
  • πŸ”„ Reset your headphones to factory (in the Mi Earphones app β†’ Reset).

⚠️ Warning: If you are using Mi True Wireless with Windows or macOS devices, dual connectivity may not work due to the limitations of Bluetooth drivers.

Optimizing sound with dual connection

When you use two pairs of headphones at the same time, the sound quality can deteriorate.

1. Audio codec setup

By default, Xiaomi smartphones use the AAC codec to transmit audio over Bluetooth. However, with dual connection, it is better to switch to SBC:

  1. Open Settings β†’ Bluetooth.
  2. Click on the icon. βš™οΈ near the connected headphones.
  3. Select the Audio Codec β†’ SBC.

This will reduce the sound quality, but increase the stability of the connection.

2. Disabling additional functions

To reduce the load on Bluetooth, turn off:

  • 🎀 Noise reduction function (ANC) (if any).
  • πŸŽ™οΈ Transparency Mode.
  • πŸ”Š Sound effects in uniform (Settings β†’ Sound β†’ Equator).

3. Use of specialized applications

For fine tuning of sound with double connection suitable:

  • πŸŽ›οΈ Wavelet (setting the equalizer for each headphone separately).
  • 🎧 Equalizer FX (preset equalizer in MIUI).
  • πŸ”Š ViPER4Android (for power users, requires root)
Why do you hear echoes in the headphones when you are connected to a double connection?
The echo is caused by the difference in the time of the audio transmission to the two devices. The Bluetooth transmitter sends the signal in packets, and if the headphones receive them in a different synchronous manner, there is an "echo" effect. This is solved by turning off the hardware acceleration of audio in the developer settings or using an external Bluetooth transmitter with APT-X Low Latency support.

Alternative ways to listen together

If you can’t connect two Mi True Wireless sets, consider alternatives:

1. Headphone splitter

The simplest solution is to use a splitter for a 3.5mm jack (if your smartphone supports wired headphones). Connect it to the audio output and attach two sets of wired headphones. The disadvantage is the loss of wireless convenience.

2. Sound synchronization applications

Some apps allow you to synchronize the sound between two smartphones:

  • πŸ“± SoundSync – broadcasts sound from one device to another over Wi-Fi.
  • 🎡 AmpMe synchronizes music for shared listening (works through the cloud).

These solutions are suitable for listening to music, but not for games or videos due to the long delay.

3 Headphones with Audio Sharing support

If listening together is critical for you, consider buying headphones with Audio Sharing support:

  • 🎧 Apple AirPods (2-3 generation) is an Audio Sharing feature for two pairs.
  • 🎧 Samsung Galaxy Buds Pro supports Dual Audio with Samsung devices.
  • 🎧 JBL Live 660NC – You can connect up to 2 devices at a time.

πŸ’‘

If you need to use two sets of headphones at once often, the best solution is to buy a model with official Dual Audio support (such as the Mi Air 2 Pro) or an external Bluetooth transmitter.

FAQ: Frequent questions about Mi True Wireless dual connection

Can I connect two Mi True Wireless kits to an iPhone?
Apple is limiting dual Bluetooth connectivity on iOS, officially only working with AirPods (a feature of Audio Sharing). Mi True Wireless will require an external Bluetooth transmitter with Dual Link support.
Why is the sound interrupted when the dual connection?
This is due to the bandwidth limitations of Bluetooth 5.0. Two audio streams require more resources than a standard connection can provide. Solutions: Reduce the distance between your smartphone and headphones. Disable other Bluetooth devices (fitness bracelets, smart watches). Switch to an SBC audio codec instead of AAC.
How do I check if my model supports Dual Audio?
Open the Mi Earphones app and check the Features section. If there's a Double Audio or Dual Mode option, your model supports this feature, and you can also check the specifications on Xiaomi's official website or in the headphone manual.
Can you connect Mi True Wireless and another brand headphones at the same time?
Technically, yes, but the stability will be lower. Xiaomi optimizes the firmware of its headphones to work in tandem with other devices of the brand. When connecting headphones from different manufacturers, there can be delays in sound or connection breaks.
Does the sound quality decrease with dual connection?
Yes, since the Bluetooth channel is divided between two devices, you can experience: a decrease in bitrate (sound quality is approaching 128 kbit / s); loss of bass and high frequencies (due to compression of the audio stream); increased latency (latency) to 150-200 ms. To minimize losses, use the SBC audio codec and turn off additional effects (for example, equalizer).
