How to get two Xiaomi wireless headphones to play together: the complete guide

Have you bought a second pair of Xiaomi headphones and want to use them with the first to create surround sound or share music? Or just want to share audio with a friend without using splitters? In this article, we will discuss all the ways to synchronize two Xiaomi wireless headphones, from official features to workarounds for models where this option is not provided by the manufacturer.

It’s important to understand that not all models support simultaneous connection to a single sound source. For example, Xiaomi AirDots Pro 2 or Redmi Buds 4 have built-in Dual Mode (or TWS Pairing), but the budget Redmi Buds 3 Lite does not. We will look at options for different scenarios, from simple connection via a smartphone to the use of additional adapters.

If you've tried to connect headphones before, but you've run into problems -- there's a section at the end of this article that addresses common bugs, and for those who are just planning to buy, we've prepared a table on compatibility of popular Xiaomi models with dual connectivity.

Which Xiaomi models support two headphones simultaneously?

Before you try to sync your headphones, check if your model supports Dual Audio or TWS Pairing, which is usually indicated in the specifications on the official website or in the instructions.

  • 🎧 Xiaomi AirDots Pro 2 – supports connecting two headphones to one smartphone via Bluetooth Settings β†’ Dual Audio.
  • 🎧 Redmi Buds 4 (Pro) – has a built-in Dual Device Connection mode that allows you to connect to two devices at the same time.
  • 🎧 Xiaomi Buds 3T Pro - supports TWS+, This allows you to synchronize two sets of headphones through the Mi Audio app.
  • 🎧 Xiaomi FlipBuds Pro – works with Dual Pairing function, but requires firmware updates to the latest version.

If your model is not on this list, it doesn’t mean that synchronization is impossible. For example, for Redmi Buds 3 Lite or Xiaomi Air 2 SE, you can use workarounds – through Bluetooth transmitters or special applications.

Method 1: Official Dual Audio (for supported models)

If your Xiaomi headphones officially support Dual Audio, it’s easiest to sync them through your Bluetooth settings on your smartphone, which works on most devices running MIUI 12+, Android 10+ or iOS 13+.

Here is a step-by-step guide for Xiaomi/Redmi/Poco smartphones:

  1. Open Settings β†’ Bluetooth and connect the first set of headphones.
  2. Click on the gear icon next to the headphones' name.
  3. Select Dual Audio or Connect the second device.
  4. Include the second set of headphones in pairing mode (usually you need to hold the button on the case for 3-5 seconds until the indicator starts flashing quickly).
  5. Select the second headphones from the list of available devices.

On iPhones or other Android smartphones, the process may be slightly different:

  • πŸ“± On iOS: Settings β†’ Bluetooth β†’ (i) next to the headphones β†’ Connect the second device.
  • πŸ€– On Android (not Xiaomi): You may need an app from a manufacturer, such as Mi Audio or HeyMelody.

Update your headphone firmware to the latest version|

Charge both sets of headphones at least 50% |

Make sure your smartphone supports Bluetooth 5.0+|

Disconnect your headphones from other devices (laptop, tablet) |

If you don’t have Dual Audio in your Bluetooth settings, try connecting both sets of headphones separately first, and then restarting your smartphone. Sometimes this helps activate the hidden feature.

Method 2: Using a Bluetooth transmitter for incompatible models

If your Xiaomi headphones don’t support Dual Audio, but you still want to use them at the same time, you can use a Bluetooth transmitter with Dual Link function. This is a small device that connects to a sound source (smartphone, TV, PC) and transmits a signal to two sets of headphones at the same time.

The most popular models of transmitters:

  • πŸ“‘ 1Mii B06 Plus – supports up to 2 headphones, low sound latency (aptX) LL).
  • πŸ“‘ Avantek APT-X β€” Compatible with most Xiaomi headphones, there is a Dual Stream mode.
  • πŸ“‘ Taotronics TT-BA09 β€” budget option, but without aptX support (the delay may be noticeable).

How to connect:

  1. Connect the transmitter to the sound source (for example, to the audio output of the smartphone through 3.5 mm β†’ Bluetooth).
  2. Include both sets of Xiaomi headphones in pairing mode.
  3. On the transmitter, activate the Dual Link mode (usually by long pressing the power button).
  4. Connect the first set of headphones, then the second.

Cons of this method:

  • ⚠️ Possible delay of sound (especially noticeable when watching video).
  • ⚠️ The sound quality may deteriorate due to double compression (source) β†’ transmitter β†’ headphones).
  • ⚠️ Additional expenses for the purchase of a transmitter (from 1,500 to 5,000 rubles).
How to reduce the latency of sound when using a Bluetooth transmitter?
1. Use a transmitter with low latency aptX support or AAC. 2. Connect the transmitter directly to the sound source (not through the USB-splitter). 3. Make sure the headphones support the same codec as the transmitter (e.g. Xiaomi AirDots Pro). 2 work AAC and SBC). 4. Turn off the microphones on the headphones – this reduces the delay on the headphones. 20-30 miss.

This method is versatile and works even with the most budget models, such as Redmi Buds 3 Lite or Xiaomi Air 2 SE. However, if you are interested in sound quality, it is better to consider buying headphones with official support for Dual Audio.

Method 3: Synchronization Applications (Android)

If you're using an Android smartphone, you can try special apps that emulate the Dual Audio feature at the software level.

  • πŸ“± SoundAssistant (from Samsung, but it works on Xiaomi) – allows you to direct sound to two Bluetooth devices at the same time.
  • πŸ“± Bose Connect – Although designed for Bose headphones, it sometimes works with Xiaomi (you need to test it).
  • πŸ“± Dual Audio Bluetooth Router – plugins for Tasker that create a virtual audio route.

Instructions for SoundAssistant:

  1. Download the app from Google Play.
  2. Connect both sets of Xiaomi headphones to your smartphone.
  3. Open SoundAssistant and go to Multiaudio.
  4. Select both devices from the list.
  5. Activate the Double Audio mode.

Important: these apps don’t always work consistently with Xiaomi headphones, especially with models on Qualcomm QCC3040 chips (such as Redmi Buds 4 Pro).

⚠️ Note: When using third-party applications for Dual Audio, the smartphone battery can be significantly drained.This is due to the fact that Android is not optimized for simultaneous transmission of sound to two Bluetooth devices.

If the applications don’t help, you can either use a Bluetooth transmitter or consider alternative methods, such as an audio splitter (but this is no longer a wireless option).

Method 4: Synchronize via smartphone + smart speaker (bypass)

If you just need to share a sound with a friend, but the headphones don't support Dual Audio, you can use a smart speaker (like the Xiaomi Mi Smart Speaker) as an intermediate device.

  1. Connect the first set of headphones directly to the smartphone.
  2. Connect the smart speaker to the same smartphone.
  3. Enable Group Play in the Mi Home app (for Xiaomi speakers).
  4. The second person connects his headphones to the speaker via Bluetooth.

The advantages of this method:

  • βœ… No need to purchase additional devices (if the column is already available).
  • βœ… You can use it with any headphones, even not from Xiaomi.

Cons:

  • ⚠️ The delay in sound can reach 0.5-1 seconds.
  • ⚠️ Sound quality is deteriorating due to dual transmission (smartphone) β†’ column β†’ headphones).

This method is suitable for listening to music or podcasts, but not for watching videos or games where synchronization of sound and image is important.

Problem Solving: Why Are Headphones Not Synced?

If you followed the instructions, but the two sets of Xiaomi headphones still don’t work together, check out the following points:

Problem.Possible causeDecision
No Dual Audio option in the settingsOutdated firmware headphones or smartphonesUpdate the software via Mi Audio or Settings β†’ About the phone
The headphones are connected, but the sound is only one.Dual Mode mode is not activated in the applicationOpen Mi Audio, find the Dual Device Connection section
The sound is interrupted or stutteredWeak Bluetooth signal or interferenceMake sure there are no obstacles between devices, restart the headphones
Cannot connect the second set.Maximum number of connected devices exceededDisable unnecessary Bluetooth devices (fitness bracelet, smart watch)

If nothing helps, try resetting the headphones to factory:

  1. Put both earbuds in the case.
  2. Hold the button on the case for 10-15 seconds until the indicator flashes red and white.
  3. Remove the headphones from the list of Bluetooth devices on your smartphone.
  4. Reconnect them.

⚠️ Attention: After resetting the settings headphones Xiaomi Buds 3T Pro and FlipBuds Pro may lose their Mi Account binding. To restore functionality, you will need to re-authenticate in the Mi Audio app.

If your Redmi Buds 4 Pro headphones stopped supporting Dual Audio after the firmware update, roll back to the previous version of the software through the HeyMelody app (the β€œRun the firmware” section).

FAQ: Frequent questions about synchronizing Xiaomi headphones

Can you use two different Xiaomi headphone sets together (like the AirDots Pro 2 and Redmi Buds 4)?
Technically, yes, but only if both sets support Dual Audio and use the same Bluetooth codecs (e.g. AAC or SBC). However, the synchronization of sound between different models can be unstable - delays or out of sync are possible.
Why is it that when you connect two headphones, the sound becomes quieter?
This is normal behavior, as the smartphone distributes the audio stream between the two devices, and the signal power is divided. To increase the volume: Turn on the audio amplifier mode in the headphone settings (if any). Use a uniform distribution of sound (in Mi Audio, choose Balanced instead of Left/Right Priority). Check if Safe Volume is activated in the smartphone settings.
Can two sets of Xiaomi headphones be connected to one TV?
Yes, but with reservations: If the TV supports Bluetooth 5.0+ and has Dual Audio (for example, Xiaomi Mi TV Q2 or Redmi Smart TV X), you can connect two sets of headphones directly. If this is not the function, you will need a Bluetooth transmitter with Dual Link (for example, 1Mii B06 Plus). On TVs with Android TV you can also use the SoundAssistant app (installed via APK).
How to check if my model supports Xiaomi Dual Audio?
There are three ways: See the specifications on Xiaomi's official website (see Dual Device Connection or TWS+). Check in the Mi Audio or HeyMelody app β€” if there's a Dual Mode partition, it's supported. Try connecting your headphones to your smartphone and looking for Dual Audio in your Bluetooth settings. If none of these things work, your model probably doesn't support this feature.
Can you use this method to watch movies without delay?
Unfortunately, even with official support from Dual Audio, audio delays of up to 100-200 ms are possible. This is due to the peculiarities of audio transmission over Bluetooth. To minimize lag: Use headphones and a smartphone with support for aptX Low Latency. Turn off the microphones on headphones (if you do not use them). Close all background applications on your smartphone. For watching videos, it is better to use wired headphones or one set of Bluetooth headphones.
