How to connect two Xiaomi headphones together: all ways for different models

Using two Xiaomi wireless headphones at once is not only convenient for listening to music with a friend, but also useful in situations where one of the headphones has failed. However, not all models support this feature out of the box, and in some cases you need to perform hidden settings. In this article, we will discuss all the working ways of syncing Xiaomi headphones, from standard pair modes to workarounds for incompatible models.

It's important to understand that Dual Mode technology (connecting two devices to the same source at the same time) and pairing two headphones are different things. The first allows you to connect headphones to two gadgets (for example, a phone and a laptop), and the second allows you to use two headphones as one stereo pair, and we will focus on the second option, since it is in demand among users of Xiaomi AirDots, Buds and other lines.

What Xiaomi models support collaborative connectivity

Not all Xiaomi wireless headphones can work in pairs with each other, here is the official list of models with support for the function "Dual Earbuds" (using two headphones as stereo pairs):

• 🎧 Xiaomi AirDots Pro 2 (and newer versions)
• 🎧 Xiaomi Air 2 Pro (with firmware) MIUI 12.5+)
• 🎧 Xiaomi Buds 3/3 Pro/4 (modifications)
• 🎧 Redmi AirDots 3 Pro (Game Mode only")
• 🎧 Xiaomi FlipBuds Pro (with update to the new version) MIUI 13)

If your model is not on this list, it doesn’t mean that synchronization is impossible. For older versions (for example, AirDots Basic or AirDots Youth), there are workarounds, but they require additional devices or software, which we will discuss in the section “Basics for incompatible models”.

⚠️ Note: Xiaomi headphones can only be synced within one model. For example, AirDots Pro 2 will not work in tandem with Buds 3 Pro, even if both devices support Dual Mode.

Standard Connection Method (for Supported Models)

If your Xiaomi headphones officially support Dual Earbuds, follow these steps:

1. Update the firmware on your headphones through the Mi Home or Xiaomi Wear app. Without the latest version of the software, the feature may not work.
2. Reset the headphone settings: press the button on the case of the charging case for 10 seconds (until the red indicator flashes).
3. Activate the pairing mode: 🔄 Get both earphones out of the case. 🔄 Press the touch panels on both headphones for 3 seconds (before the beep). 🔄 Wait for the white light to flash on both devices.

Connect to the device.

• 📱 On Xiaomi phone go to Settings → Bluetooth.
• 📱 Select a device with your model name (e.g., "Mi True Wireless Earphones 2" from the list").
• 📱 Confirm the conjugation.

Once successfully connected, both earbuds will work as a stereo. To check synchronization, play an audio file with clear channel separation (e.g., a left/right voice test track). If the sound is only in one earbud, repeat the pairing procedure.

Update the firmware through Mi Home|Reset settings (10 seconds of button retention)|Activate the pairing mode (3 seconds on the sensor)|Connect via Bluetooth on your phone-->

⚠️ Note: Some models (e.g. Buds 3 Pro) require manually activating Dual Earbuds mode in the settings of the Xiaomi Wear app after you connect. → Headphone settings → Sound mode → stereo.

Bypass solutions for incompatible models

If your Xiaomi headphones don't support official synchronization, you can use one of the alternative methods: they require additional devices or programs, but they can achieve a similar result.

Method 1: Using a Bluetooth transmitter

The most reliable way for older models (AirDots Basic, Youth Edition) is to use an external Bluetooth transmitter with Dual Link support. For example, the Avantek BTA-200 or 1Mii B06 Plus adapters allow you to connect two devices at the same time.

• 🔌 Connect the transmitter to the sound source (phone, PC) through 3.5 mm or USB-C.
• 🔄 Transfer the transmitter to Dual Link mode (usually with a long push of a button).
• 🎧 Connect the first Xiaomi headphone to the transmitter.
• 🎧 Connect the second headphone (it will be defined as the second device).

The downside of this method is the latency of up to 100-150 milliseconds, which is noticeable when watching videos, and it is not critical for music or podcasts.

Method 2: Software Duplication of Sound (Android)

On Xiaomi phones with root rights or through ADB, you can enable the Bluetooth audio duplication function, which will allow you to send audio to two devices at the same time.

adb shell settings put global bluetooth_dual_app true


adb shell settings put global bluetooth_dual_ho true

After completing the commands, restart your phone and try connecting both earbuds. This method does not work on all firmware and can cause connection stability problems.

Customization of sound for synchronized headphones

After successfully connecting two headphones, Xiaomi may need to adjust the sound further to avoid imbalance or delays.

• 🔊 Channel balance: In Bluetooth settings on your phone (Settings) → Sound. → Bluetooth balance: check that both earphones play the sound equally loudly.
• 🎵 Bluetooth codecs: For models with aptX or LDAC (For example, Buds 3 Pro select the appropriate codec in the developer settings (Settings) → The phone. → Version. MIUI → 7 times to tap → Developer settings → Bluetooth codec).
• 🔋 Power Saving Mode: Turn it off for headphones in the Xiaomi Wear app to avoid connection breaks.

Critical feature for Xiaomi Buds 3 Pro models: when using a codec LDAC Sound delay can be as high as 200ms, making it unsuitable for games or video. AAC or SBC.

💡

If one of the headphones has a quieter sound, try cleaning the speaker grid with a soft brush or compressed air, and often the problem lies in the dust-filled grille, not the settings.

Frequent problems and their solutions

Even after successful synchronization, users face typical problems, and here are the most common ones and ways to fix them:

Problem 1: The sound is only in one headphone

Reasons:

• 🔹 The headphones are not synchronized with each other (re-pairing is required).
• 🔹 In the settings of the phone, Mono mode is selected instead of Stereo.
• 🔹 One of the headphones is discharged or incorrectly located in the ear (the proximity sensor blocks the sound).

Solution: Reset your headphone settings (10 seconds of holding the button on the case) and repeat the connection procedure. Make sure that Settings → Bluetooth → [Your headphones] → Sound is selected mode "Stereo".

Problem 2: Permanent connection breaks

Reasons:

• 📶 Bluetooth signal weakened due to obstacles (walls, furniture).
• 🔋 Power saving mode on the phone or headphones is enabled.
• 📱 The phone runs background optimization for the Xiaomi Wear app.

Decision:

1. Turn off power saving mode for Bluetooth in Settings → Battery → Battery Optimization → Select applications → Xiaomi Wear → No restrictions.
2. Reconnect the headphones at a distance of no more than 1 meter from the phone.
3. Disable other Bluetooth devices (fitness bracelets, smart watches) that may cause interference.

💡

If the headphones keep turning off, try changing the Bluetooth codec to SBC – it is less demanding for connection stability, although it is inferior in sound quality.

Problem 3: Different volumes in headphones

This is a typical problem for Redmi AirDots 3 and AirDots Pro models.

1. Open the Xiaomi Wear app.
2. Go to the device → Headphone settings → Sound balance.
3. Use a slider to manually adjust the volume of each earpiece.

How to use two Xiaomi headphones on iPhone

Xiaomi’s Dual Earbuds technology is optimized for Android devices, but there are ways to connect two headphones to an iPhone.

• ❌ Xiaomi headphones do not support the Audio Sharing function on the iPhone directly.
• ✅ You can use a Bluetooth transmitter with Dual Link support (e.g. Avantek). BTA-200).
• ✅ On the jailbreak iPhone, you can activate the hidden Dual Audio feature via the DualPair Tweak (requires experience).

Instructions for connection via transmitter:

1. Connect the transmitter to your iPhone via Lightning port or Bluetooth (depending on the model).
2. Activate the Dual Link mode on the transmitter.
3. Connect the first Xiaomi headphone.
4. Connect the second headphone (it will be defined as the second device).

On the iPhone without jailbreak and transmitter to synchronize two headphones Xiaomi impossible – this is a limitation of iOS firmware.

Comparison with headphones of other brands

Other manufacturers have a two-headphone sharing feature, but it's implemented differently. Here's a comparison table.

Xiaomi’s main advantage is the low price of Dual Mode headphones, but Apple and Samsung’s solutions are both a winner in terms of stability and versatility, allowing different headphone models to be used together.
