Modern wireless headsets have become an essential accessory for smartphone owners, offering freedom of movement and high-quality sound without unnecessary wires. Especially popular among users of the Xiaomi ecosystem, the Redmi AirDots series, which combines compactness, affordable price and stable connection. However, the process of initial configuration or re-connection of devices can sometimes cause difficulties for inexperienced users, especially if it comes to specific MIUI functions.
In this guide, we will discuss in detail all the steps of connecting headphones to a smartphone, paying attention to the nuances of the Android operating system in the shell of MIUI. You will learn how to properly activate the pairing mode, what to do if the phone does not see the device, and how to adjust the sound for maximum comfort.
The correct operation of the Bluetooth module depends not only on the serviceability, but also on the correctness of the software settings. We will consider both standard procedures and methods of deep cleaning of the list of devices that help in difficult cases. Understanding the principles of the data protocol will help you respond faster to any malfunctions in the periphery.
Preparation for the first connection and activation
Before you try to connect devices, you need to make sure that the headset is ready to go. If you just unpacked Redmi AirDots, they are usually in standby or off mode. To activate, you need to remove both headphones from the charging case. Indicators on the cases should start flashing white, indicating that you are on and go into network search mode.
It is important to note that when the devices are first turned on, they often require automatic pairing (left and right earphone) before connecting to the phone, a process that takes a few seconds. If the indicators flash at different frequencies or colors, then the synchronization between the channels is not complete, and the phone can only see one of them or not see at all.
Make sure your smartphone has a wireless module on, so lower the notification curtain and find the appropriate icon. Some versions of MIUI require a long-term tap on the icon to go to advanced settings to check the visibility of the device for other gadgets, a critical step that makes finding new devices impossible.

Step-by-step instructions for pairing devices
The process of pairing Xiaomi smartphone and headphones Redmi standardized, but has its own features in the interface. Open the settings menu and go to the Bluetooth section. The system will automatically start scanning available space. In the list of "Available devices" should appear the name of your model, for example, Redmi AirDots or AirDots Basic.
Click on the device name in the list. On the screen of the smartphone, a request for confirmation of pairing with an indication may appear. PIN-The code (usually 0000), although in modern versions of Android this happens automatically. Once successfully connected, you will hear a characteristic beep in the headphones, and in the status bar of the phone will appear the icon of the battery charge of the headset.
If the connection is successful, the system may suggest installing a special application for advanced management, but for basic operation this is not required. The key point is that after the first successful pairing, the reconnection will occur automatically when the case is opened.

If two identical device names appear on the list, delete both of them and repeat the procedure of resetting the headphones so that they reunite into a stereo pair before connecting to the phone.
Sound tuning and control in MIUI
Once the connection is successful, it is recommended to perform a basic audio profile setting to achieve the best playback quality. In Xiaomi smartphones, the Sound and Vibration section in the settings is responsible for this. Here you can activate the visualizer, adjust the equalizer or select preset scenarios such as Pop, Rock or Jazz, which adapt the frequencies to a particular genre of music.
Playback is controlled through touch zones on headphone cases. Usually, a single touch is responsible for pause or playback, a double touch is responsible for switching the track, and a triple one is responsible for returning to the previous one. Long-term retention often activates the voice assistant or changes the volume, depending on the version of the firmware of the headset. The exact combination can be found in the instructions or checked experimentally.
For advanced users, a hidden developer settings section is available where you can change the Bluetooth codec. Go to Settings β About Phone β MIUI version (click 7 times) and then in the developer section, find the Bluetooth Audio Codec. Choosing an aptX or LDAC codec (if supported by both devices) can significantly improve the audio quality compared to a standard SBC.
- π§ Volume: Adjusted by buttons on the case or slider on the phone screen independently.
- π Calls: Double touch during a call will complete the call, and retention may reject the incoming call.
- π£ Assistant: activation of Mi AI Google Assistant is used (by long-term pressing) on the touch zone.
Solving Visibility and Connectivity Problems
It's not uncommon for users to have a smartphone that just doesn't detect the headphones, so first of all, you have to make sure that the headset is actually in pairing mode, if the lights don't flash fast or alternately, maybe the device is already connected to another gadget nearby, and automatic reconnection is a convenient feature, but it can interfere when you set up.
Another common cause is a crowded Bluetooth cache or software failure in the communication module, which is helped by a simple restart of the Bluetooth service or a full reboot of the smartphone, and it is also worth checking whether the phone is not on flight or energy saving mode, which can limit the operation of wireless interfaces to save charge.
β οΈ Note: If the headphones were previously paired with another phone, they may try to connect to it automatically.Stop Bluetooth temporarily on other devices within a 10-meter radius.
The table below shows the main symptoms of problems and how to eliminate them:
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| Phone can't see headphones | The pairing mode is not activated | Put it in the case, take it out and pinch the sensors. |
| Only one headphone works. | Lost synchronization between L and R | Complete reset (Hard Reset) |
| Low volume. | The volume of the OS is not synchronized | Enable "Absolute volume" in the settings |
| Frequent communication gaps | Interference or battery discharge | Charge the case and move away from Wi-Fi sources |
Resetting and re-synchronization
If standard methods don't work, you need to reset the headset completely.This procedure returns the device to factory settings and forcibly triggers the process of finding a pair between the left and right headphones. For Redmi AirDots, this is done by keeping the touch zones on both headphones for long periods of time while they are in the case or outside it (depending on the model).
The indicators should flash red several times and go out, which means clearing the memory, then you need to activate the pairing mode again, and it is important to do these actions away from other devices that the headphones may have been connected to earlier to avoid automatically capturing the connection.
Once reset, go to the Bluetooth settings on your phone, find your model in the list of previously saved devices, and click Forget Device or Unpair. Only after clearing the connection history on the smartphone side can you start searching again, which ensures that the old configuration files will not conflict with the new settings.
Secret combination for resetting
Optimizing energy consumption and stability
To ensure stable performance in the background, MIUI sometimes requires allowing player applications to run without restrictions, go to the battery settings, find the music service you are using, and select No Limits mode, which will prevent the application from being forced to stop by the system, which can lead to a stoppage of audio playback.
You should also pay attention to the Bluetooth version. Modern Xiaomi smartphones support standards of 5.0 and higher, which provides better energy efficiency and range compared to older versions. If you have an old phone, the radius of confident reception can be reduced, and the phone will lose communication when you move away from the signal source.

The stability of the connection depends on the version of the Bluetooth protocol and the absence of physical obstacles between the phone and the headphones in the pocket.
β οΈ Warning: Don't let the headphones go completely out of action until they stop responding to charging. Lithium polymer batteries can go deep and be difficult to repair.
- π Charging: Use the original cable or certified analogues with a current of no more than 1A.
- π§Ή Contacts: regularly wipe contacts in the case with dry cloth to ensure a reliable charge.
- π‘ Temperature: Avoid operating and storing headphones at extremely low or high temperatures.
