How to connect 2 Bluetooth headphones to 1 phone at a time: Xiaomi

Xiaomi’s modern smartphones offer the widest range of media functionality, allowing users to not only listen to music but also share it in real time. The ability to stream audio to two different devices simultaneously opens new horizons for sharing movies, listening to podcasts or organizing mini-party on the go. However, many device owners still don’t know that this feature is built into the shell of MIUI and the latest HyperOS by default.

Unlike standard Android smartphones, which require searching for third-party applications, the Xiaomi ecosystem offers a native solution through the Bluetooth menu. This ensures a stable connection without delay and desynchronization of sound. You do not need to be a technician to set up dual audio output, just follow a clear algorithm of actions.

It's worth noting that the quality of playback depends on the version of the Bluetooth protocol and the headphones themselves. TWS-Headsets from different manufacturers at the same time, there may be nuances in volume or channel balance, but the system is effective at encoding the signal for two receivers.

Verification of system compatibility and requirements

Before you start setting up, you need to make sure that your device is technically capable of supporting the Dual Audio function.Most modern Redmi, POCO and Xiaomi models released after 2019 are equipped with Bluetooth 5.0 modules and higher, which is a basic requirement for stable operation. Older versions of the protocol may not cope with the transfer of two data streams without significant quality losses.

Also critical is the operating system version. Device owners should check for updates in Settings → About Phone. The audio distribution function was optimized in MIUI 12 and further developed in MIUI 13, 14 and HyperOS. On very old interface builds, this option may not be available or may not work properly.

Pay attention to the type of accessories you connect. The system works best when both devices use the same codec, such as SBC or AAC. If one earphone supports only the basic profile and the second one supports advanced aptX, the smartphone can force you to switch to the lowest common denominator to ensure synchrony.

⚠️ Attention: Connecting more than two devices at the same time MIUI The system limits the number of active audio outputs to two to prevent congestion and lags.

Check the battery power of both headsets. The process of pairing and maintaining two connections consumes the energy of the phone's Bluetooth module more actively than usual. Low charge can lead to a sudden break in communication with one of the devices at the most inopportune time.

Standard method of connecting via Bluetooth settings

The main way to activate the mode is to use a standard system interface, so you first need to turn on Bluetooth on your smartphone and put the first pair of headphones into pairing mode, usually by pressing the button on the case or the device itself before the indicator flashes.

Once you successfully connect the first headset, repeat the procedure for the second pair, a new gadget will appear in the list of available devices, and it is important to pair it through the settings menu, not through the widget in the curtain, to make sure that the profile is correctly registered.

When both devices are listed as "Connected," the system automatically redirects the audio stream to both channels. You can control the volume of each device separately or jointly through a volume slider. In some versions of the firmware, a separate icon of two triangles appears, indicating an active handout mode.

If the sound is only in one pair, check the playback settings. Sometimes the player app or video service may have its own mixer, where only one output device is selected, switch between tracks or restart the media file to activate the second channel.

Use of the dual audio function in MIUI and HyperOS

In current Xiaomi shells, the feature is often put on a separate menu or activated automatically when you connect a second device. For manual control, go to Settings → Bluetooth → Additional settings (or click on the gear next to the connected device).

HyperOS offers even more flexible management. In the control center (curtain) when the Bluetooth menu is opened, sometimes you will see a list of all active connections. By clicking on the deployment icon, you will see which devices are receiving the signal, and you can eliminate one of them without breaking the connection completely.

The thing about HyperOS is that it's an improved synchronization algorithm, which analyzes the latency of each channel and makes micro-adjustments to make the left and right earphone sound at the same time, which is especially important when watching movies.

💡

If you use dual audio mode frequently, add a Bluetooth widget to your desktop for quick access to the list of devices without logging into the deep settings menu.

Consider that activating this feature can slightly increase the power consumption of a smartphone. While modern Qualcomm and MediaTek processors are effective at coding, the background work of the two threads requires resources.

Connecting Headphones of Different Brands at the Same Time

One of the most common questions is about compatibility between devices from different manufacturers. Fortunately, Bluetooth is the universal standard. You can easily connect Xiaomi Buds with the Samsung Galaxy Buds or any other wireless headsets to the same phone.

But there are technical nuances. Different brands use different implementations of codecs. If one pair supports aptX Adaptive and the other pair only runs SBC, the phone will choose SBC for both to avoid out-of-synchrony, which can cause the sound to become less quality than it could be.

There may also be differences in maximum volume, with one pair of headphones sounding quieter or louder than the other when the slider is in the same position on the smartphone, and it is recommended to use volume control on the headphones themselves (if designed) or third-party equalizer apps.

When mixing brands, the system may require a second device to be trusted again, which is standard Android security procedure to prevent unauthorized access to the audio output. Just confirm the request on the smartphone screen.

Solving problems with desynchronization and sound

The most common problem is desynchronization, where one pair of headphones has a split second behind the other, often treated by resetting Bluetooth settings. Go to Settings → Bluetooth, find the problem device, press the gear and select Forget the device, then pair again.

If the problem persists, try clearing the Bluetooth cache. Go to Settings → Apps → All apps, search in the “Bluetooth” list, click “Clean” and select “Clear Cache.” Don’t worry, your saved pairs won’t be deleted, but temporary error files will be erased.

⚠️ Note: Do not try to connect devices that are more distant 5-7 To work in Dual Audio mode, both receivers must be in close proximity to the source smartphone.

Sometimes a conflict causes a particular application. For example, YouTube or Netflix can cache the playback buffer differently for different channels. Try restarting the application or clearing its data. Also, switching the codec to the developer menu, if you have enough skills, helps.

Third-party apps and developer menus

In the rare cases where regular funds don't work (like very old versions of MIUI), you can use the developer menu. Activate it by quickly clicking on the MIUI Version seven times in the About Phone section. Then, in the developer menu, look for the Bluetooth Audio Codec and try changing it to the SBC that is most compatible.

There are also third-party apps from Google Play, such as Dual Audio or Bluetooth Connect, that are pushing the second channel, but their effectiveness on modern Xiaomi smartphones is questionable, as they cannot bypass the system limitations of Android and the built-in MIUI functionality is more stable.

Using third-party software can lead to increased battery discharge and unstable system operation. Rely on native shell tools. If the function does not work out of the box, most likely, the hardware of the Bluetooth module does not support simultaneous transmission of two streams.

Remember, experimenting with Bluetooth system settings should be done with caution. A return to factory settings is always possible through a network reset, but it is best to avoid drastic changes unnecessarily.

Frequently Asked Questions (FAQ)

💡

Main conclusion: For stable operation of two pairs of headphones use devices with Bluetooth 5.0+ and upgrade MIUI to the latest version; mixing different brands is possible, but can reduce the quality of the codec.
