Modern smartphones from Xiaomi, Redmi and Poco are equipped with advanced Bluetooth modules that ensure stable audio streaming in high resolution. However, the first pairing process often raises questions among users, especially when working with new models of wireless headsets in the Mi True Wireless Earbuds series or Redmi Buds. The correct sequence of actions ensures not only instant connection, but also the correct operation of all functions, including noise cancellation and touch control.
In this article, we will go into detail about the connection algorithms for different types of devices, look at the features of the MIUI and HyperOS interface, and provide solutions for typical synchronization errors.
It’s worth noting that Xiaomi’s ecosystem offers advanced features for its accessories that only become available after proper initial pairing. Ignoring some nuances can lead to headphones only running in mono mode or not being able to update the firmware.
Preparation of wireless headphones for pairing
The first critical step is to put the headset into detection mode. Many users mistakenly believe that it is easy enough to open the case lid, but new devices often require active action. If you use a model with a touchpad on a case, such as Mi True Wireless Earbuds Basic 2, you need to hold the function button until the indicator starts flashing white.
For models that don't have a button on the case, the procedure should be different. You need to remove both headphones from the case at the same time. It is at this point that they go into Pairing Mode mode, which is signaled by the rapid flashing of LEDs. Keep the devices next to the smartphone, at a distance of no more than 10-15 centimeters to avoid interference.
⚠️ Attention: If the headphone lights flash different colors or don't blink at all, they may be discharged. Before trying to connect, make sure that the case and the headphones themselves have a charge, leaving them on charge at least on the back of the headphone. 15-20 minute.
There is also a nuance for devices previously connected to other smartphones: If the headset automatically connects to the previous gadget, the new device may not see it, in which case you must first turn off Bluetooth on the old phone or remove the device from the list of stored on it.

To reset Bluetooth settings on Xiaomi headphones, you often need to press the button on the case for 10-15 seconds until the indicator flashes red three times, which will return the device to factory settings.
Bluetooth configuration in the MIUI and HyperOS interface
Xiaomi's shell interface provides easy access to wireless network settings. First, unlock your smartphone screen and lower the notification curtain from top to bottom. Find the Bluetooth icon and make sure it's active (blue). If the icon isn't in quick access, go to the main settings menu.
Deeper tuning is available via the Settings → Bluetooth path. In this section, the system will automatically start scanning available devices in range. The list is updated in real time, so if you just put your headphones in pairing mode, they should appear in the Available Devices list within seconds.
Special attention should be paid to the Bluetooth version supported by your phone. Modern models Xiaomi 13, Xiaomi 14 and flagship Poco support Bluetooth 5.2 and higher, which allows you to transmit sound in LDAC or AptX Adaptive codecs. To activate high audio quality, you sometimes need to additionally go to the menu "Sound Quality" or "Bluetooth Codec", which appears only after connecting a compatible headset.
Owners of HyperOS shell devices should be aware of the fast connection feature. When you open a case next to an unlocked Xiaomi smartphone, an animated window may appear on the screen offering to connect the device, an analogue of Google’s Fast Pair technology, optimized for the manufacturer’s ecosystem.
Step-by-step connection instruction TWS-headset
The process of pairing true wireless stereo headsets (TWS) has its own specifics, different from conventional Bluetooth headphones. Here it is important to synchronize not only the phone and headphones, but also the left channel with the right. Below is a detailed instruction that should be followed sequentially.
☑️ Connection algorithm TWS
Once you click on the device name in the Bluetooth list on your smartphone screen, the system can request confirmation, and in some cases, the code will appear on the screen that you need to check, although in modern versions of Android this happens automatically, the process takes no more than 5-10 seconds.
If the connection is successful, you'll hear a distinctive beep in the headphones, and the phone's status bar will have a headset battery icon, which indicates that the data protocol is activated correctly, and you can now check the sound playback.
⚠️ Warning: When you first connect, be sure to allow access to contacts and call logs if the appropriate window pops up. Without this permission, you will not be able to see the name of the caller or use the voice assistant through headphones.
The important thing is to check the touch control, which can be different by default than you want, and often requires an Internet connection and a Mi Account profile, although the basic features work offline.
Connecting wired headphones and adapters
Modern Xiaomi smartphones rarely feature a classic 3.5mm connector, so users have to use wired headphones with USB Type-C interface or adapters. When connecting such devices, the system automatically switches the audio output, but sometimes this process requires user intervention.
If you use the original Mi Hybrid Earphones with a Type-C connector, they need to be instantly detected. If you use third-party accessories or cheap adapters, the phone may not recognize the device, which is because not all Type-C cables support analog audio or digital audio transmission via DAC.
You can use the engineering menu or third-party apps to diagnose wired connection problems, but you should check the sound settings first. → Sound and vibration and make sure that in the "Use" section USB-Accessories" (if such a item is in your version of the OS) the correct action is selected when connecting.
| Type of connection | Required adapter | Support for Hi-Res Audio | Probable problems |
|---|---|---|---|
| 3.5mm Jack | The original adapter | Depends on the DAC. | Background noise, quiet sound |
| USB Type-C (digit) | Not required | Yes (LDAC/aptX) | Incompatibility of the protocol |
| USB Type-C (analogue) | Not required | No. | Lack of sound on some models |
| Bluetooth 5.0+ | Not required | Yeah (with codecs) | Sound delay in games |
When using third-party adapters, there is often a situation where the sound is available but the microphone is not working, a technical limitation of many budget converters that implement only the A2DP profile (stereo) but do not support the headset profile (HSP/HFP).
Using the Xiaomi Earbuds app to customize
To unlock the full potential of Xiaomi and Redmi headphones, it is highly recommended to install the Xiaomi Earbuds app (formerly known as Mi True Wireless Earbuds) that is available in the Google Play Market and allows you to manage options not available in the standard Bluetooth menu.
Once installed and first launched, the app will automatically detect the connected headphones, and in the interface, you'll find the equalizer, noise reduction (ANC) settings, transparency mode, and gesture management, and from here, updates are made to the firmware of the headphones themselves and the charging case, which often fixes connection bugs.
Why update the headphone firmware?
You can also configure the headphone search feature, which makes the headset louder if you lose it in the apartment, and it displays the exact percentage of charge for the left and right earphone separately, which is much more informative than the standard indicator.
Some features, such as automatic switching between devices or low latency in game mode (Game Mode), are activated exclusively through this software. Without installing the application, you will be limited to the basic functionality of music playback.
Solution: Headphones are not connected or are not working stable
Even if all instructions are followed, technical difficulties can arise, and the most common problem is that the phone sees the device but does not connect, giving an error: "Failure to hide" in which case you need to perform a complete cleanup of the list of associated devices.
Go to Bluetooth settings, find your headphones in the list of "My devices", click on the gear or information icon next to the name and select "Unpair" or "Forget device". After that, repeat the procedure for entering pairing mode on the headphones and connect them again.
⚠️ Note: If the headphones are no longer synced with each other (only one channel works), you need to reset to the factory settings (Hard Reset), usually by clamping buttons on the headphones or a case on the case on the headphones. 20-30 For the exact combination for your model, look in the instructions.
Another cause of unstable communication can be interference from Wi-Fi routers or microwave ovens operating at 2.4 GHz. Try to move away from the source of interference or temporarily turn off Wi-Fi on your smartphone to check the stability of the Bluetooth connection.
💡
90% of connection problems are solved by completely removing the device from the phone’s memory and re-pairing the smartphone reboot.
If neither method works, check the smartphone system update list. Sometimes the problem lies in a bug of the Android operating system itself, or MIUI, which was patched in a more recent security patch.
