How to connect two headphones to a Xiaomi phone: all ways (2026)

If you want to listen to music or watch a movie with a friend, but you only have one Xiaomi smartphone? Connecting two pairs of headphones to the same phone is a real task, although not always obvious. In this article, we will discuss all the current ways to synchronize two Bluetooth headphones or a combination of wired / wireless devices to Redmi, POCO, Mi and other models of the brand.

The standard Bluetooth in Xiaomi smartphones (even flagships like Xiaomi 13 Ultra or Redmi Note 12 Pro+) out of the box supports connecting only one audio device at a time. However, there are workarounds: from hidden MIUI features to third-party applications and hardware adapters. We tested all methods on current firmware (including MIUI 14/15 based on Android 13/14) and selected only working solutions.

Importantly, not all methods are equally convenient. Somewhere you will need to buy additional equipment (for example, a Bluetooth transmitter), and somewhere you will have to put up with the delay of sound. To save your time, we have arranged the methods from the simplest to the most complex - choose the right one!

Built-in Dual Audio function in MIUI (selected models only)

Some Xiaomi smartphones based on MIUI 12.5+ have a hidden option Dual Audio, allowing you to broadcast audio to two Bluetooth devices at the same time. The problem is that the feature is not officially available on all models – even within the same line (for example, the Redmi Note 11 Pro supports, and the Redmi Note 11S does not).

To check for the presence of the function:

1. Open Settings → Connections and Sharing → Bluetooth.
2. Put the first pair of headphones on.
3. Click on the gear icon next to the headphones' name.
4. Try to find the Dual Audio item or Double Audio.

If you don't have an option, don't despair. On some firmware, you can activate it through a hidden developer menu:

##83781##

Type this code in the Phone app, then search for the Bluetooth Audio HAL partition and turn on the Dual Audio Mode. On models with a Snapdragon 8 Gen 1/2 chipset (such as the Xiaomi 12S Ultra), this method works more stable than on devices with MediaTek processors.

2.Use of Bluetooth transmitter (universal method)

If the built-in features don’t work, the most reliable way is to buy a Bluetooth transmitter with Dual Link support (such as the Avantek APTX-LL or 1Mii B06 Pro), which connects to the phone via a 3.5mm audio jack or USB-C and relays the sound to two pairs of headphones at the same time.

Pros of the method:

• 🎧 It works with all Xiaomi models (including the old Redmis). 4X or Mi A1).
• 🔊 Minimum sound delay (important for watching video).
• 🔋 Does not run out of battery (transmitter is powered by its own battery).

How to connect:

1. Insert the transmitter into the audio or USB-C port of the phone.
2. Turn on the TX (Transmitter) mode on the transmitter.
3. Activate device search on both pairs of headphones.
4. Connect the headphones to the transmitter (not the phone!).

⚠️ Note: Cheap transmitters (up to 1000) ₽) Often have a noticeable audio delay when watching videos. For synchronous playback, choose models with support for aptX Low Latency or AAC.

3. applications for sound duplication (SoundAssistant, Bluetooth Dual Audio)

If you don't want to spend money on a transmitter, try specialized applications. They don't always work on MIUI (due to manufacturer restrictions), but in some cases they do.

Top.-3 tested applications:

Instructions for SoundAssistant (the most reliable option):

1. Download the app from Google Play.
2. Connect the first pair of headphones via standard Bluetooth.
3. Open SoundAssistant and select Dual App Sound.
4. Enable the Multi-Output Audio option.
5. Connect the second pair of headphones via Bluetooth in the app menu.

⚠️ Note: Xiaomi with MediaTek processors (e.g. Redmi) 10C or POCO M4 Pro) SoundAssistant can cause overheating with prolonged use!

💡

If the sound in the headphones begins to "break", try in SoundAssistant to reduce the bitrate to 192 kbit / s in the codec settings.

4. Connecting wired + Bluetooth headphones at the same time

If you have a wired headphone (with a 3.5mm or USB-C connector) and one pair of Bluetooth, you can combine them without additional devices, which works on all Xiaomi where the audio jack is stored (for example, the Redmi Note 10 Pro or the POCO X3 Pro).

How to set up:

1. Connect the wired headphones to the phone.
2. Activate Bluetooth and connect the wireless pair.
3. Open a music playback app (such as Mi Music or Spotify).
4. In the notification panel, select Output of sound → Both devices.

Limitations of the method:

• 🔌 Does not work on models without a 3.5 mm connector (for example, Xiaomi) 12T or Redmi K50).
• 🎵 Sound delay between wired and Bluetooth headphones can reach 100-150 miss.
• 🔋 Quickly drains the battery (simultaneous operation of Bluetooth and audio chip).

5.Using a USB-C hub with two audio outputs

For Xiaomi owners without a 3.5 mm connector (for example, Xiaomi 13 Lite or Redmi K60), there is a solution - a USB-C hub with two audio outputs (for example, UGREEN CM521 or Baseus 7-in-1).

Advantages:

• 🎧 Zero sound delay (both headphones connected via wire).
• 🔊 Maintains high quality sound (up to) 24 bit/96 keto).
• 🔋 Does not load the Bluetooth module of the phone.

How to choose a hub:

⚠️ Note: Some hubs (especially cheap Chinese ones) may not work properly with the Internet. MIUI Before buying, check the reviews for your Xiaomi model!

6. Alternative solutions: splitters and Wi-Fi headphones

If none of the above methods work, consider the less obvious options:

A. Headphone splitter (Y-cable)

Suitable only for wired headphones with a 3.5 mm connector. Buy a splitter (for example, Belkin RockStar) and connect two pairs of headphones to one output. Cons: the sound will be mono (if the headphones have a microphone), and the volume will be distributed between the two pairs.

B. Wi-Fi headphones (e.g. Bose QuietComfort Ultra)

Some premium headphones support connection to the same Wi-Fi network and synchronization with each other, minus the high price and limited choice of models.

Synchronization applications (e.g. Rave or Teleparty)

If the goal is to watch a movie together, you can use synchronized viewing services, which stream video in the browser, and everyone listens to the sound through their headphones, suitable for Xiaomi of any model.

💡

The most versatile method for Xiaomi is a Bluetooth transmitter, which works on 100% of devices, does not require root rights and gives minimal audio latency.

Comparison of all methods: which one to choose?

To facilitate the selection, we have compiled a comparative table on the key criteria:

For most Xiaomi users, the best solution is:

• 📱 For flagships (Xiaomi) 12/13, POCO F4 GT) — Try out the built-in Dual Audio.
• 🎧 For budget models (Redmi) 10/11, POCO M4) — Buy a Bluetooth transmitter.
• 🎵 To listen to music (without video) - use SoundAssistant.
• 🎬 For movie viewing, only a transmitter with aptX Low Latency or USB-C hub.
