Today’s Xiaomi ecosystem users often face the need to connect audio devices quickly and efficiently. Wireless headphones have become an indispensable accessory for sports, travel and work, but the process of their initial synchronization sometimes raises questions. Proper tuning ensures not only stable connection, but also the full potential of high-resolution codecs.
In this guide, we will discuss in detail the algorithms of actions for various operating systems. You will learn how to activate the pairing mode on various models, from budget Redmi Buds to flagship Xiaomi Buds 4 Pro.
We'll focus on troubleshooting, because even the most reliable gadgets sometimes require user intervention. Understanding how Bluetooth works will help you avoid common mistakes when you first start. Let's start by getting your smartphone ready.
Preparation of the smartphone and activation of Bluetooth
Before you try to link devices, make sure your smartphone is ready to go. First check the battery level, as low charge can cause the radio to work unstable. Turn Bluetooth on in Settings → Bluetooth or through the Quick Access Panel.
It is important that there are no active connection conflicts in the system. If another audio device is already connected to the phone, it can intercept the signal or prevent the detection of a new gadget, turn off unnecessary devices or temporarily turn off Bluetooth to reset the cache of connections.
💡
Before connecting new headphones, restart your smartphone – this will clear the Bluetooth system cache and eliminate 80% of potential detection errors.
For Miui or HyperOS users, it is recommended to update system services through the GetApps app. This will ensure that you have up-to-date drivers for fast synchronization. Also make sure that geolocation is enabled, as in modern versions of Android this is required to accurately identify the device.
Android Connection Algorithm (Miui and HyperOS)
Xiaomi and Redmi smartphone owners have a unique advantage: instant pairing, which requires the headphones to be in a case with an open lid next to the unlocked phone, and the system will offer a connection card on the screen.
If the automatic window doesn't appear, go manually. Press and hold the function button on the case (or touch zones on the headphones themselves, depending on the model) until the indicator flashes white. This means activation of Pairing Mode mode.
☑️ Pre-conjugation check
In the list of available devices, find the name of your model, for example, Xiaomi Buds 3T Pro. Click on it to initiate communication. After a successful connection, the system may suggest updating the firmware through the Bluetooth settings menu - agree, as this improves stability.
⚠️ Warning: Do not remove the headphones from the case until the indicator lights up or blinks. Early removal may interrupt the process of entering the pairing mode.
Connection with iPhone and other smartphones
iOS devices don't support Xiaomi's proprietary fast-connect protocols, so the process looks classic. Put the headphones in search mode, holding the button on the case for about 3-5 seconds. The indicator should flash often.
Open Bluetooth settings on your iPhone and wait for the device to appear in the list of “Other devices”. Click on the model name to connect. For full functionality (for example, displaying the battery charge of each headphone), it is recommended to install the Xiaomi Earbuds application from the App Store.
On smartphones from other manufacturers (Samsung, Realme, Honor), the algorithm is similar to the iPhone. However, for access to advanced equalizer settings and gesture control, the best way to use the universal application Xiaomi Earbuds. It is available on Google Play and allows you to customize the behavior of touch zones.
Sound tuning and gesture management
Once paired successfully, it is important to adjust usage scenarios. In the application or system settings (Settings → Bluetooth → Pressing a gear next to the device), you can change the actions when you touch. Playback control is often configured by default, but this can be changed.
- 🎵 Single touch: usually responsible for Play/Pause or call in a voice assistant.
- 📞 Double touch: often used to answer a call or switch tracks.
- 🔇 Triple touch: can activate noise reduction mode or cause a previous track.
- 🗣 Retention: switching between modes ANC (noise reduction) and transparency.
The equalizer is also worth adjusting, depending on the model, you may have Bass, Vocal, Jazz presets or manual frequency tuning, and the right low frequency settings (usually in the 60-250 Hz range) will greatly improve your perception of EDM and Hip-Hop music.

Comparison of methods of connecting different series
Different headphone lines may have slight differences in activation procedure, and below is a table that helps you quickly navigate the nuances of popular series.
| Headphone series | Method of activation | Search mode indicator | Annex |
|---|---|---|---|
| Redmi Buds | The button on the case (3 seconds) | Orange blinking | Xiaomi Earbuds |
| Xiaomi Buds 3/4 | Button on the case / Auto | White flashing | Systems/Earbuds |
| FlipBuds | Sensor on the case | Pulse. | Xiaomi Earbuds |
| AirDots (old) | Sensor retention (5 seconds) | Red and white. | Mi True Wireless |
Note that older AirDots models require resetting before new pairing if they were previously used with another phone. This requires clamping the sensors for 20 seconds before flashing red. Newer Xiaomi Buds models are smarter and often reset automatically when placed in the case of another device.
Solving Connection Problems and Resetting
If the headphones are not visible to the phone or the sound is interrupted, the first thing you do is complete a Hard Reset. Place the headphones in the case, open the lid and press the function button for 10-15 seconds until the indicator flashes orange three times. After that, remove the device from the Bluetooth list on the phone ("Forget the device") and try to connect again.
⚠️ Note: When you reset your headphone settings, all saved profiles and custom equalizer settings will be deleted. You will have to configure them again through the app.
A common problem is to desynchronize your left and right earbuds when only one is playing, in which case cleaning the list of paired devices on all the gadgets they've ever connected to will help. Then put the headphones in the case, close it for 10 seconds and open it again to restart.
💡
90% of connection problems are solved by completely removing the device from the phone’s memory (“Forget the device”) and then resetting the headphones themselves to factory settings.
Also check the Bluetooth version on your smartphone. AptX Adaptive or LHDC codecs require support from the transmitting device to work. If the phone is old, the headphones will work in baseline SBC mode, which may affect sound quality, but not the stability of the connection.
