Today's users are rarely confined to a single gadget: a smartphone is in their pocket, a laptop is on their desk, and a tablet is next to them. In this ecosystem, there is a constant need to switch audio output between devices, which creates inconveniences when incoming calls or changing the source of content. Many owners of Xiaomi equipment wonder whether it is possible to automate this process and make the headset serve multiple audio sources at once without manual reconnection.
Fortunately, Bluetooth technology has advanced so far that it is becoming standard even for budget models, but it has its own nuances on Xiaomi devices, depending on the version of the MIUI or HyperOS shell, as well as the model of the headphones themselves. In this article, we will discuss the technical aspects of the Multipoint protocol, ways to bypass system constraints and proven methods for setting up stable connections.
Before we get into complex manipulations, it is worth clarifying that “simultaneous operation” is often understood as two different scenarios: the first is broadcasting the same sound to two different headsets (evening movie mode); the second, more popular scenario is connecting one pair of headphones to two signal sources (smartphone and PC), and our article focuses on the second option, which requires competent configuration of communication profiles.
Bluetooth Multipoint Technology and Xiaomi Support
The fundamental basis for connecting to multiple devices is Bluetooth Multipoint, which allows the headset to maintain an active connection to two audio sources at the same time. It is important to understand that support for this feature depends not only on the smartphone, but also on the chip installed inside the headphones themselves. If your Redmi Buds or Mi True Wireless device does not have hardware support for multipoint, it will be impossible to software activate it.
Xiaomi’s ecosystem is twofold: On the one hand, the company is actively implementing new communication standards, but on the other hand, there are often software restrictions in the MIUI shell that block automatic switching between active devices. The system can forcefully break the connection to the tablet when a phone call arrives, even if both devices “see” the headset, this is due to the priority of HFP (hands-free) profiles over A2DP (stereo sound).
⚠️ Note: Not all Xiaomi headphones support full-fledged Multipoint. Budget versions often only know how to quickly switch between devices, but not work with them in parallel.
To check the compatibility of your equipment, you need to consult the model specifications. Usually flagship lines such as Xiaomi Buds 3 Pro or Buds 4 Pro are equipped with the necessary modules. Owners of older or simple models such as AirDots will have to face restrictions that can be partially circumvented, but full synchronization will not be achieved.

Preparation of headphones and resetting of settings
Before trying to configure a complex connection scheme, it is critical to ensure that the pairing profiles are clean. If your headphones were previously connected to a dozen different devices, they could accumulate “junk” in their memory, preventing the correct operation of communication protocols, starting with a complete reset of accessories to factory settings.
The reset procedure depends on the form factor of the device. TWS-True wireless stereo models usually need to place headphones in a case, open the lid and pinch the touchpad or physical button on the case on the case. 10-15 For overhead models such as Mi Headphones Comfort, the key combination may differ, but the principle remains the same - a long clamp of the on button or a special reset button.
☑️ Preparation for Multipoint setup
Once reset, remove the device from the Bluetooth list on all devices where it was previously listed, a mandatory step, as encryption key conflict is a common reason for refusing to repair, and only after the Bluetooth cache is completely cleared can a new pair be created.
Instructions: Connect to two devices at the same time
The process of setting up simultaneous operation requires consistency. You can't just turn on Bluetooth on both devices and hope for a miracle. The algorithm of actions must be strict: first, a connection is created with the main device (usually a smartphone), and only after successfully establishing a connection and turning off the audio transmission can you move to the second gadget.
Turn on Bluetooth on your Xiaomi smartphone and pair with your headphones as usual. Make sure the sound plays. Then, without turning off the headphones, go to the Bluetooth settings on your smartphone and click "Disable" (not "Forget the device", namely, break the connection). Now activate the search on the second device (tablet or laptop) and perform pairing. After successfully connecting the second device, return to the first and connect the headphones again.
| Phase | Action on Device 1 (Smartphone) | Action on Device 2 (Planchet/PC) |
|---|---|---|
| 1. Preparation | Turn on Bluetooth, find headphones | Bluetooth is off. |
| 2. The pairing | Perform pairing and sound check | Waiting. |
| 3. Switching | Break the connection (Disconnect) | Turn on Bluetooth, find headphones |
| 4. Finals. | Reconnect the connection | Confirm the conjugation |
If it's successful, the system should display Connected status on both devices, and when you play music on the tablet, the sound will go into the headphones, and if you call your smartphone at that point, the headphones should automatically switch to the ringtone, which is the sign that Multipoint is working.
Use of the Xiaomi Earbuds app
For owners of original accessories Xiaomi is an indispensable tool is the proprietary application Xiaomi Earbuds (or Mi Wear for older models). It is through this software that you can often activate hidden functions or update the firmware of the headset, which adds support for new protocols.
Inside the app, you need to go to the device settings and find the partition associated with the connection or Bluetooth. Some versions of the software include the option “Dual connection” or “Smart Connect.” If you have this option, you need to activate it. You can also check the firmware version here. Often problems with simultaneous operation are solved by updating the headphone firmware.
⚠️ Attention: Updating the firmware of the headphones through the application requires that the smartphone is next to the case, and the charge was at least 30».
The app also allows you to set priorities, for example, you can set a scenario where the sound from a video on a tablet will automatically pause when you call your phone. Without using Xiaomi Earbuds, such fine-tunings often remain unavailable to the user.
MIUI and HyperOS settings for stable operation
MIUI shells and the new HyperOS are known for aggressive power optimization, which sometimes harms the background processes of Bluetooth. To prevent the headphones from spontaneously turning off or losing communication with the second device, you need to make changes to the system settings of the smartphone.
First of all, you should prevent the system from killing processes related to Bluetooth and Xiaomi services. Go to Settings → Apps → All applications, find Bluetooth and Xiaomi Earbuds (if installed). From the Battery or Energy Saving menu, select No Limits mode, which allows communication services to work in the background without restrictions.
💡
If the sound is interrupted when switching, try the developer settings (the MIUI version is 7 times) to find the option “Bluetooth MAP” or “Absolute Volume” and experiment with their on/off.
It is also worth checking the privacy settings. in newer versions of Android and MIUI Bluetooth access may be restricted. Make sure system services have permission to use geolocation, as scanning of Bluetooth devices is often tied to the Internet. GPS-module.
Problem Solving: Headphones can't see the second device
The most common problem is that the second device simply can't see the headphones, even though they're busy with the first gadget, which is a classic symptom of the headphones not going into detection mode. In Multipoint mode, the headset must be visible to pair, even if it's already connected. The solution is often manually pairing the headphones.
To do this, while the headphones are connected to the phone, you need to pinch the touch zones on both headphones (or the button on the case) for 5-7 seconds, until the indicator starts flashing quickly white, this will force the port to open for a second connection. If this does not help, perhaps the limit of connections in the memory of the headphones is exhausted.
The table below shows common errors and methods of their elimination:
| Problem. | Possible cause | Decision |
|---|---|---|
| The second device does not find headphones | Detection mode is off. | Press the headphone buttons for mode (Pairing) |
| There is only sound on one device. | No support for Multipoint | Check model specifications, use manual switching |
| Persistent communication breaks | Wi-Fi interference or low charge | Remove the router, charge the case, reset the network settings |
💡
If software methods don't work, the problem is probably the hardware limitations of the headphone chip, in which case no firmware will add Multipoint support.
Alternative ways to switch sound
If your headphone model doesn't technically support two-source connectivity, it's too early to despair. There are workarounds to minimize inconvenience. The easiest way is to use the Quick Switch feature in the Xiaomi ecosystem, as long as both devices are authorized under the same Mi Account.
In this case, when you pause the video on your tablet and play music on your phone, the system will suggest switching the audio output. It's not a real Multipoint, but the switching speed is fractions of a second. You can also use third-party Bluetooth management apps that hang in the background and automatically reconnect the headset when the media player changes state.
Another option for advanced users is to use a PC as a gateway, so if you connect your headphones to your computer and you connect your smartphone to your computer through a Windows Connection app or something like that, the sound from your smartphone will be streamed through your PC into your headphones, and that creates a single audio environment, albeit with a slight delay.
