How to set up Xiaomi headphones with two devices at once

Today's users are rarely confined to one gadget in their daily lives. Usually, a smartphone is in their pocket, a smartwatch is on their wrist, and a laptop or tablet is on their desk. In this ecosystem, there is a constant need to switch audio devices between sound sources. The standard procedure for breaking off communication with one device and connecting to another is time-consuming and annoying. Fortunately, Bluetooth 5.0 and higher technology, implemented in Xiaomi and Redmi products, allows you to solve this problem elegantly.

The simultaneous connectivity feature, often called Dual Device Connect, is becoming the standard for premium and mid-range wireless headsets. It allows Xiaomi headphones to maintain an active connection with two signal sources. You can watch videos on a tablet and instantly answer a call from your smartphone without touching your Bluetooth settings. However, implementation of this technology has its own nuances, which depend on the specific accessories model and operating system version.

In this guide, we will look at the technical aspects of multipoint in Chinese devices, how pairing algorithms can work, how audio streams can conflict, and how to fix typical synchronization errors, and understanding these processes will help you get the most out of your headset and forget about manual switching.

Technology Limitations and Dual Connect Support

Before trying to configure synchronization, you need to make sure that the hardware support of the feature. Not all Xiaomi or Redmi headphones are capable of multi-connection. This is usually available in models with active noise cancellation (ANC) or flagship series, such as the Xiaomi Buds 3 Pro or Redmi Buds 4 Pro. Budget versions are often deprived of this option due to the limitations of the chipset or battery savings.

Bluetooth Multipoint allows the receiver (earbuds) to log into the networks of two transmitters, but this does not mean that the audio stream is transmitted simultaneously from both sources. The system works on the principle of priority: if the second device starts playing or a call is received, the first source is paused or its sound is mixed, this is a critical point for understanding the logic of the gadget.

⚠️ Warning: Attempting to activate dual-connection mode on models without hardware support can lead to unstable operation of the Bluetooth module and rapid battery discharge.

To check the compatibility of your model, you should consult the official specification on the manufacturer’s website or instructions. Also, information about Dual Device support is often added in firmware updates, so even if the feature was missing at the time of purchase, it can appear after the update through the Xiaomi Earbuds app.

• 🎧 Check out the exact headphone model in the official Xiaomi catalog.
• 📱 Make sure that the current version is installed on smartphones MIUI or hyperos.
• 🔄 Update firmware headphones to the latest version through the app menu.
• 📶 Make sure that both devices use Bluetooth 5.0 or higher.

It's important to differentiate between modes of operation. Some models allow you to stream sound to two pairs of headphones from the same phone, but not vice versa. We're interested in a scenario where one headset listens to two phones. These are fundamentally different technologies, and we shouldn't confuse them.

Preparing devices for synchronization

Successful Dual Connect settings require proper pre-training of all participants. Chaotic switching on and off Bluetooth often causes devices to “remember” old configurations and refuse to work in the new mode.

The first step is to complete a complete reset of previous pairing settings, which ensures that Xiaomi headphones start connecting from scratch, without MAC address conflicts. If the headset has records of old devices in memory, they can automatically try to connect to them in the background, intercepting priority.

Once reset, you need to reconnect your headphones to the first device, which will be your main smartphone, which is the most common sound coming from, make sure the connection is stable, the music is playing and the microphone is working correctly, and only after a full check can you move to the second stage.

The second device should be in close proximity, preferably not more than one meter away, which will ensure maximum signal power when establishing a secondary channel, in some cases, distance plays a critical role, especially if one of the devices has a weak Bluetooth module.

Step-by-step instructions for connecting to two devices

The process of activating the dual connection mode in the Xiaomi ecosystem is as automated as possible, but requires compliance with the sequence of actions. IP-Addresses or complex developer commands, all of the control is centered in the mobile application interface.

Open the Xiaomi Earbuds app on your main smartphone. Go to the connected headset settings. Find the connection section that can be called Dual Device Connection or Dual Device Connection. Activate the switch. The interface will prompt you to find the second device.

On your second smartphone or tablet, turn on Bluetooth and start looking for new devices. Your headphones should appear on the list of available gadgets. Click on them to pair. At which point, a request to confirm the connection of the new device may appear on the screen of the main device — agree with it.

Once the procedure is completed successfully, the app will display two connected devices with their names, so you can switch between sound sources, for example, run a video on a tablet, and then take an incoming call on your phone, and the video must automatically mute or pause, giving way to the voice of the interlocutor.

Setting priorities and managing sound

When both devices are connected, the system starts to work on the algorithm of priorities. Usually, the phone call has the highest priority, then the system sound (notifications), and the background media playback (music, video) has the lowest priority, but the user can influence this behavior through settings.

The Xiaomi Earbuds app often has a choice of the type of second device available, you can specify that it is a tablet, a computer or another phone, which helps the system handle A2DP and HFP profiles correctly. For example, when connecting to a PC, priority can shift towards computer notifications, which is not always convenient.

⚠️ Note: When two sound sources are working simultaneously, micro-latency or audio compression artifacts may occur, as the channel bandwidth is shared between the two data streams.

Volume control also has its own peculiarities. Often the volume is adjusted independently on each device. If you turn down the sound on your phone and then switch to a tablet, you may need to adjust the level again. This is normal protocol behavior, because the amplification levels on different gadgets may differ.

• 🔊 Media volume and call volume are regulated separately.
• 📞 The incoming call interrupts any other sound playback.
• 🎬 Suspend video on one device does not automatically trigger audio on another device.
• ⌨️ Voice assistants are activated from the device on which they were called.

So for comfortable use, it's important to get used to the logic of switching, so if you're listening to music from your laptop and you pick up your phone, the music doesn't stop on its own until you run some audio on your phone or make a call, and that allows you to use your headphones as a versatile speaker for different tasks.

Solving Typical Connection Problems

Despite the technology's fine-tuning, users can run into difficulties, and the most common problem is that Xiaomi headphones see both devices, but only sound comes from one, or the switching happens with a long delay, often due to Bluetooth cache or outdated drivers.

If the connection is unstable, try to forget the device on both gadgets and repeat the pairing procedure again. Sometimes it helps to reboot the Bluetooth stack on smartphones. Turn on the flight mode for 10 seconds, then turn it off. This will force all communication modules to reconnect.

💡

If the sound is interrupted when two devices are running, try disabling high-resolution codecs (LDAC or aptX HD) in the Bluetooth developer settings, leaving the standard AAC or SBC for improved channel stability.

Another common situation is channel desynchronization, with the left earpiece playing from one device, the right earpiece playing from another, or the sound coming from only one ear, which is a sign of a failure in the synchronization between the earphones themselves (TWS link), solved by placing both earbuds in the case, closing the lid and waiting for 10-15 seconds, followed by reopening.

If one of the devices doesn't see the headphones in search mode at all, check if they are already connected to the third gadget. Xiaomi headphones can support memory of several devices, but only hold an active connection with two. If there are more connections in the list, new ones may not be initiated.

Compatible with Android and iOS operating systems

Xiaomi’s ecosystem is most fully realized in conjunction with Android smartphones, especially with the shells MIUI and HyperOS. It provides instant pop-up pairing, charge animation and full access to the settings of the equalizer. Dual Connect mode in the bundle of Android-Android works most stable.

When using iOS devices (iPhone, iPad), functionality may be limited. Apple strictly controls the operation of the Bluetooth peripheral. While the basic dual-connection feature will work, management through the Xiaomi Earbuds app on iOS may have limitations. Some advanced priority settings may not be available.

Mixed pairs, like iPhone + Android or Windows PC + Android, work but require manual prioritization. Windows computers sometimes mishandle the “busy” signal from headphones, trying to continue broadcasting sound even when an incoming call is on the phone.

It is important to note that for the feature to work on different OSes, both devices need to support the Bluetooth Multipoint standard. Older versions of iOS or Android (below version 10) may not support this technology at the system level, even if the headphone hardware allows.
