How to connect 2 headphones Xiaomi AirDots to one phone: the complete guide

Xiaomi AirDots wireless headphones (including Redmi AirDots, Mi True Wireless Earphones and their modifications) have become popular due to the combination of price and quality. However, many users face the problem: after buying a second pair of headphones or using separate headphones from different sets, the question arises: can you connect two headphones to one smartphone?

The answer is yes, but with nuance. Depending on the headphone model and the firmware version, the synchronization process may differ. In this article, we will discuss all possible ways to connect two AirDots simultaneously, including official methods for supported models and workarounds for others, and learn how to avoid typical errors and what to do if the headphones refuse to work together.

What Xiaomi AirDots models support connecting two headphones at the same time

Not all Xiaomi wireless headphones can work in tandem with “foreign” headphones, here is the official list of models that support the Dual Mode function (simultaneously connecting two independent headphones to the same source):

• 🔹 Xiaomi AirDots Pro 2 / Pro 2s — with firmware version 1.4.0 and higher
• 🔹 Redmi AirDots 3 / 3 Pro – Requires an update via Mi Home
• 🔹 Mi True Wireless Earphones 2 / 2s — plant-support
• 🔹 Xiaomi Air 2 / Air 2s / Air 2 Pro – only after manual update

If your model is not on this list, it doesn’t mean that you can’t connect two headphones, but there are alternative methods, but they may require additional manipulation of the settings of the smartphone or even third-party software, which we will discuss in the corresponding section.

Important: Even if your model supports Dual Mode, both headphones must be from the same series. For example, you can not sync AirDots Pro 2 with Redmi AirDots S - these are different lines with incompatible protocols.

Preparation of headphones before connection

Before trying to sync two headphones, you need to follow several mandatory steps, and skipping any of them can lead to malfunctions or complete inability to connect.

⚠️ Warning: If at least one of the headphones has been paired with another device, it must be reset beforehand, otherwise it can automatically connect to the old source, ignoring new commands.

Here's what we need to do:

1. Charge the headphones. Make sure both earphones are at least 50 percent charged. Low charge can interrupt the synchronization process.
2. Reset: For most AirDots models, the reset is done by holding the touch button for 10-15 seconds until the red and white light flashes.
3. Firmware check. Update your headphones through the Mi Home app (if available).Odd firmware can block the Dual Mode feature.

For models with Dual Mode support, it is also recommended to turn on sync mode, for example, in Redmi AirDots 3 this is done by triple touching the touchpad on one of the headphones (usually on the right), after which the indicator should start flashing blue and red alternately.

Charge both headphones up to 50%+

Reset settings (hold the button 10-15 seconds)

Update the firmware via Mi Home (if available)

Enable synchronization mode (triple touch for supported models)-->

Official method: Dual Mode connection (for supported models)

If your headphones are on the list of compatible models, use the official instructions. This method is the most reliable and does not require third-party applications.

Step-by-step:

1. Open Bluetooth settings on your smartphone (Android or iOS).
2. Turn on Bluetooth and wait until the first headphone appears on the list (e.g. Redmi AirDots). 3_R).
3. Connect to it. After successful connection, turn off the headphone via the Bluetooth menu (don't turn off the earphone itself!).
4. Go back to the device list and find a second headphone (e.g. Redmi AirDots) 3_L). Get him on the hook.
5. Now hold the touch buttons on both headphones for 3-5 seconds at the same time until you hear the connection beep.
6. In the Bluetooth menu of the smartphone should appear one device called the type Redmi AirDots 3 Stereo.

Critical: Some Android firmware (especially MIUI 12-14) may need to disable the Auto Connect function for each headphone separately before syncing them together, otherwise the system will try to connect to only one device.

💡

If the headphones don’t sync, try connecting them to another smartphone (for example, on pure Android without a shell). MIUI.

Alternative methods for unaccompanied models

If your model doesn't support Dual Mode, you can try workarounds. They're less stable, but they work in some cases.

Method 1: Using a Bluetooth splitter

There are special Bluetooth transmitters (for example, Avantek BTA-200 or Mpow BH129) that allow you to connect two output devices to a single source.

1. Connect the splitter to the smartphone via Bluetooth.
2. Connect the first headphone to the splitter.
3. Connect the second headphone to the second channel of the splitter.

The disadvantage of the method is the sound delay (~50-100 ms) and possible interference.

Method 2: Applications for duplication of audio stream

On Android, you can use apps like SoundAssistant or Bluetooth Auto Connect that emulate audio output to two devices at once.

• 🚫 This method does not work on iOS due to system limitations.
• 🚫 Possible lags and reduced sound quality.
• 🚫 Not all headphone models are supported.

Method 3: Manually create a stereo pair via ADB (for advanced users only)

On some Android firmware, you can force audio output to two Bluetooth devices via ADB commands.

adb shell settings put global bluetooth_dual_app true


adb shell settings put global bluetooth_hfp_for_call false

After completing the commands, restart your smartphone and try connecting both earbuds. Note that this method can lead to unstable Bluetooth operation.

⚠️ Attention: use ADB-commands on bootloader-locked devices can cause warranty resets. On iPhones, this method is not possible.

Typical problems and their solutions

Even if you follow instructions correctly, you can have failures, and here are the most common problems and ways to fix them:

• 🔊 One earphone is not connected: check if it is in mono mode (Mono Mode). To switch to stereo, hold the touch button for 8 seconds until the double beep.
• 🔊 The sound goes only to one headphone: in the Bluetooth settings of the smartphone, find the connected device and turn on the “Use for Media” option for both headphones.
• 🔊 Headphones are constantly turned off: turn off energy-saving mode for Bluetooth in the battery settings (Settings) → Battery → Energy saving for applications).
• 🔊 Impossible to connect to iPhone: on iOS, some AirDots models require pre-reset via Mi Home on Android device.

If none of these methods worked, try updating the headphone firmware manually.

1. Download the latest firmware version for your model from the official Xiaomi website (support section).
2. Connect the headphones to the PC via Bluetooth.
3. Use the Mi Flash Tool or QFil for firmware (instructions are attached to the firmware file).

Compatibility with different operating systems

Dual Mode can work differently depending on the smartphone’s operating system, and here are the key features:

Android (MIUI, pure Android, Samsung One UI, etc.):

• 📱 Nana MIUI 12-14 may need to disable the Quick Connection feature in Bluetooth settings.
• 📱 On Samsung with One UI Sometimes you need to manually select a profile. A2DP earpiece.
• 📱 On pure Android 10+ There is usually no problem, but you may need to enable "Dual Audio" in the developer.

iOS (iPhone/iPad):

• 🍎 Dual Mode support is limited. only works with Mi True Wireless Earphones 2/2s and AirDots Pro 2s.
• 🍎 On iOS 15+ You may need to disable Automatic Switching in Bluetooth settings.
• 🍎 Sound can be delayed up to 200 ms due to the protocol. AAC.

Windows/macOS:

On a PC, connecting two AirDots at the same time is only possible through a Bluetooth brancher or specialized software (for example, Voicemeeter for Windows).

💡

The most stable models on the iPhone are models with a Qualcomm QCC3040 chip (for example, AirDots Pro 2s).

How to check that both earphones are working correctly

Once you've successfully connected, you need to make sure that the sound is synchronized and non-distorted.

1. Stereobalance test: Turn on a track with clear channel separation (e.g., left/right voice test files) and the sound should go to both earphones simultaneously.
2. If the headphones support Hands-Free Profile (HFP), call the other phone and check if the microphone is working on both headphones.
3. Distance test. Step 5 to 10 meters away from your smartphone. If the sound starts to break, it may indicate a weak Bluetooth signal.

If you notice that:

• 🎧 The sound in one headphone is quieter – check the balance settings in the player or smartphone availability settings.
• 🎧 Echoes or interferences – try changing the Bluetooth codec to SBC (developer-setting).
• 🎧 Headphones are periodically turned off – disable other Bluetooth devices nearby (they may interfere with the device).

For accurate diagnosis, you can use applications like Bluetooth Auto Connect (Android) or nRF Connect (iOS/Android), which show signal strength and connection stability.
