Modern users often face the desire to share music or audiobook with the interlocutor, without using external speakers. The question of how to link 2 headphones Xiaomi, becomes especially relevant for owners of smartphones of this brand, who want to use two pairs of wireless headsets at once. MIUI HyperOS and Reconnection Functions TWS-model.
This is a task that depends on your headphone model and the software version of your phone, and in some cases, it's about bringing sound to two different pairs of devices, in others, reconnecting the right and left earphones of the same headset, and our guide will help you understand the nuances.
There are several use cases: You might want to listen to music with a friend by connecting his Xiaomi Redmi Buds and his Mi True Wireless Earbuds to the same signal source, or you need to synchronize left and right channels if they're out of sync, both of which require different approaches to configuring the Bluetooth interface.
Dual Audio Technology in Xiaomi Ecosystem
The fundamental basis for multiple audio devices to work simultaneously is the Bluetooth protocol. Starting with certain versions of Android and the MIUI shells, the company has implemented support for transmitting audio streams to two independent receivers, which means that your smartphone can act as a transmitter for two different pairs of headphones.
However, not all models support this feature natively at the system level: Older devices or budget segments may require the use of third-party applications or special codecs. It is important to understand that latency can vary between two different models of headphones.
⚠️ Note: When connecting two different headphone models, the volume and balance of sound may differ due to differences in hardware implementation of the speakers.
To be successful, both devices must be paired with the phone in advance, the system must see them as separate, familiar gadgets, and then activate multithreaded audio.
- 🎧 Support for Bluetooth 5.0 and higher for stable communication.
- 📱 Presence of the shell MIUI 12 and newer for the native Dual Audio function.
- 🔋 Charge of both devices at least 20% to avoid connection breakage.
- 📶 No active heavy Wi-Fi network loads in the 2.4 GHz band.
Connecting two different pairs of headphones to the same phone
If your goal is to stream the sound to two independent headsets, such as the Xiaomi AirDots 3 and Mi Noise Cancelling Earbuds, the algorithm will be as follows: First, make sure that both pairs are in pairing mode and visible in the list of available devices.
Go to your smartphone's Bluetooth settings. Find the first device and connect. Wait for a successful connection to be confirmed and the headphone icon to appear in the status bar. Then, without turning off the first device, find the second pair in the list and also initiate the connection.
In some versions of MIUI, after connecting the second device, the system will automatically prompt you to select the output mode. If this does not happen, click on the gear next to the name of the active device in the Bluetooth menu, which may contain the option "Audio output" or the icon with multiple speakers, allowing you to select both devices.
☑️ Checking before connection
It is worth noting that with such a connection, playback control (pause, track switching) may not work correctly from one of the devices, usually the commands process the device that was connected first or has priority in the system.
Synchronization of left and right earphone (TWS Pairing)
Often, the question "how to connect" users mean a situation where one headphone TWS-The other headset is not seeing, like the left Redmi Buds 4 Lite, the right one is silent, or the phone defines them as two different devices, and this requires resetting and re-synchronization.
First, place both earbuds in the charging case. Make sure the contacts are clean and the devices start charging (indicators are on fire). Then you need to completely reset the headset settings. The way you reset depends on the model: this can be prolonged retention of touch areas or use a physical button on the case.
Dumping pattern (typical):
1. Remove the headphones from the case.
Press and hold the sensors for 15-20 seconds until the indicator flashes.
3. Put it in the case, close the lid for 10 seconds.
4. Open the lid and reconnect.After reset, remove the old pairing Xiaomi Earbuds from the Bluetooth list on your phone ("Forget the device"). Only then take the headphones out of the case at the same time. They must first find each other (usually one indicator flashes), and only then become visible to the smartphone.
⚠️ Note: If the headphones continue to be defined as two different devices after reset, try charging the case completely within 2 hours, as a low charge can disrupt the synchronization controller.
Use of Mi Share and Audio Share
In the Xiaomi ecosystem, there is an Audio Share feature that allows you to stream audio from a single compatible device (like the Xiaomi Sound Bar or smart speaker) to wireless headphones. While it’s not quite the same as connecting two headphones to a phone, it’s an alternative way to share sound.
But when you talk about audio transfer between two Xiaomi phones, Mi Share technology works here, and you can stream audio from one smartphone to another that already has headphones on it, which is convenient if one of the users has a dead phone, but there's a spare headset.
To activate, you need to open the control center on both devices and select the audio transmission option, and the quality of the transmission in this case depends on the distance between the smartphones and the version of the Bluetooth protocol.
| Model headphones | Dual Audio support | Synchronization method | Features |
|---|---|---|---|
| Mi True Wireless 2 | Yeah (via phone) | Automatic. | Low delay |
| Redmi Buds 3 Pro | Yes. | The button on the case | Noise suppression |
| Xiaomi FlipBuds Pro | Yes. | Sensory management | High quality sound |
| AirDots Basic 2 | Limitedly. | Manual reset (5 times) | Requires accurate timing |
What if the sound is only in one earpiece?
Setup through the Xiaomi Earbuds app
For advanced configuration and diagnosis of communication problems, it is recommended to use the official Xiaomi Earbuds app (or Mi Wear for global versions), which allows you not only to control noise cancellation, but also to update the firmware of headphones, which often solves problems of unstable connection.
Inside the app, you can see the charge of each headphone separately. If one of them discharges faster, it can indicate a battery problem or that it is constantly trying to reconnect to the master earpiece. Updating the firmware through the app often corrects logical errors of the controller.
The app also has a headphone search feature, so if you lose one of them in the room, the app will make it squeak, which helps make sure that the connection between the phone and the particular earphone is correctly established.
- 🔄 Automatic update of the firmware to correct bugs.
- 🎚️ Set up the equalizer to compensate for the differences in sound.
- 🔍 Diagnostics of battery charge of each module separately.
- ⚙️ Reassignment of Sensory Control Functions.
⚠️ Warning: During firmware updates, headphones should be in close proximity to the phone (not more than 30 cm) and should not be used to play back sound.
💡
If the app doesn't see the headphones, try connecting to them first via the standard Bluetooth menu, then running the Xiaomi Earbuds app. Sometimes initial pairing through the system menu is a must-have trigger for activating advanced features.
Solution: desynchronization and interference
Even after setting it up correctly, users may experience periodic out-of-synchronization, interruption or echoes, and interference from other wireless devices operating in the 2.4 GHz band, such as Wi-Fi routers or microwave ovens, is often the cause.
Try to move away from the radiation sources. If you're in a place with a large crowd and a lot of Bluetooth devices (metro, airport), the stability of the pairs of headphones can be compromised by the physical limitations of the protocol, in which case it's better to use a wired connection or reduce the quality of the codec in the developer's settings.
In the Android Developer menu, you can find Bluetooth Audio Codec. Switching from SBC to AAC or aptX (if supported by both devices) can improve transmission stability but increase power consumption.
💡
The stability of the connection of two headphones depends on the distance to the source of the signal and the absence of physical obstacles between the phone and the headset.
Conclusion and final recommendations
You can link 2 Xiaomi headphones in a variety of ways depending on your ultimate goals, whether it’s a movie night with a friend using Dual Audio or a recovery. TWS-Headsets, algorithms of actions are clearly defined by the manufacturer, the main thing is to follow the sequence of actions and monitor the relevance of firmware.
Remember, software failures are temporary, resetting and reconnecting regularly helps keep devices on track, and if none of the software methods worked, it may be the hardware of one of the modules that is the problem.
Use this knowledge to make music more comfortable. Xiaomi’s technology allows you to flexibly manage the audio stream, turning your smartphone into a full-fledged media center for the company.
