Xiaomi’s modern smartphones have long since ceased to be just callers, becoming multimedia centers where the quality of the sound played out is paramount. The transition to wireless technology relieves the confusion of cables, allowing you to enjoy music or podcasts while jogging, in the gym or just in public transport. However, the process of primary pairing can sometimes raise questions for users who are first encountering the Android ecosystem or the new version of the MIUI shell.
The connection procedure is almost universal for all models, whether it is a budget Redmi Note or flagship Xiaomi 14, but has its nuances depending on the version of the operating system. The key point is to put the headphones themselves in active detection mode, since simply turning on power often does not activate visibility for the smartphone. In this article, we will analyze each step in detail, look at hidden codec settings and help solve the typical problems that users face when syncing devices.
First, make sure your phone has a communication module activated. Without this basic step, any further manipulation will be meaningless. Often users forget that after a system update or reset, access to the Bluetooth module can be restricted or disabled for energy saving purposes.
Preparation of the device and activation of Bluetooth
Before you look for external devices, you need to make sure that your smartphone is ready for data transfer. In the shell of MIUI and the new HyperOS, the control of wireless interfaces is put in the top curtain of notifications, which makes the process as convenient as possible. Just swipe from top to bottom to open the control panel and find the icon in the form of a stylized letter "B".
If you prefer the classic path or the icon is hidden, go to the main settings menu. Find the Settings → Bluetooth section or search the settings by typing the word "Bluetooth." Make sure the activation slider is translated into "On." The system will automatically start scanning the available devices, but to save charge, it is better to start the search immediately before pairing.
⚠️ Note: Do not leave the Bluetooth module on permanently in crowded areas with large networks, as this can speed up battery drain and create a vulnerability to so-called "Bluetooth tracking" by ad networks.
It's also important to check the Android version and security updates.Older firmware versions may not support the latest encryption protocols or high-resolution codecs, such as LDAC or aptX Adaptive. Go to About Phone and check for updates to ensure connection stability.
💡
For quick activation of Bluetooth without unlocking the screen, set up the voice command "Enable Bluetooth" via Google Assistant or Xiao AI, if your region supports this feature.
Transfer of headphones to pairing mode
The most common mistake of beginners is to try to find headphones on the list when they are in normal operation. For a Xiaomi phone to see the headset, it must be in a special Pairing Mode. The method of activating this mode varies dramatically depending on the design and manufacturer of the accessory.
For fully wireless models (TWS) with a case, the algorithm is usually as follows:
- 🎧 Place both headphones in the charging case and leave the lid open.
- 🎧 Find a function button on the case case case (often hidden inside or behind).
- 🎧 Press the button on 3-5 seconds before the indicator flashes quickly (usually in white or blue).
- 🎧 If the button is not there, touch the touch zones on both headphones at the same time and hold the button. 5-7 seconds.
For full-size or neckband models, the procedure most often involves holding the power button. Press and hold the power button for about 7-10 seconds, even after the device sounds to turn on. The indicator should start flashing red and blue, which signals readiness to search.
What to do if the indicator does not flash?
Some models, such as Xiaomi or Haylou, support the quick pairing function through a pop-up, but for this they must be previously tied through the Mi Wear app or Xiaomi Earbuds. In standard mode, they still require manual translation to visibility mode.
Connection and Configuration Process in MIUI
Once the headphones are in active search mode, pick up your smartphone. The list of available devices, which is updated in real time, should show the name of your headset. On Android, device names often contain a model or brand, for example, Redmi Buds 3 Pro or JBL Tune 510BT.
Tap the name of the device in the list. You can see a request for confirmation of pairing with an access code on the screen. In 99% of cases, for modern devices, you do not need to enter the code, just click Connect or OK. The system automatically exchanges encryption keys and establishes a secure connection.
☑️ Checklist of successful connection
Once the connection is successful, the system will suggest setting up a usage profile, so you can allow access to contacts and call logs to see the caller's name, or you can deny it for privacy purposes, and it's also important to check which audio profile is active by default -- usually A2DP (for music) and HFP (for calls).
Xiaomi smartphone owners can take advantage of advanced audio settings. Go to Settings → Sound and vibration → Headphones (the path may vary depending on the version of MIUI). Here you can access the equalizer, spatial sound settings and choose whether to prioritize quality or stability of the connection.
| Parameter | Description | Recommendation |
|---|---|---|
| SBC codec | The basic codec is supported by all devices. | Use if maximum range and stability are important. |
| AAC codec | Standard for Apple devices, good quality on Android. | The best choice for most iPhone and Android users. |
| AptX codec | Qualcomm technology for high-resolution audio transmission. | Turn on Lossless music on compatible headphones. |
| LDAC codec | Sony technology provides the highest bitrate. | Only for audiophiles under ideal signal reception conditions. |
Mi Wear Application and Ecosystem
For owners of Xiaomi, Redmi and Haylou headphones, installing the branded Mi Wear app (formerly Mi True Wireless) is highly recommended.This software opens up access to hidden features that are not available through the standard Android menu.
The app can update the firmware of the headphones themselves. The manufacturer regularly releases updates that improve noise reduction (ANC) and fix connection errors. Update is done via a smartphone: the file is downloaded to the phone and then broadcast to the headset over Bluetooth.
⚠️ Warning: During the update of the firmware headphones categorically do not open the connection or carry the phone away from the case. interruption of the process may lead to the inability to turn on the headphones in the future.
The app also has a touchscreen setting, so you can reassign actions like double-touch for pause, triple-touch for assistant, long-term hold for noise reduction switching. Standard settings often don't match the user's habits, so personalization through Mi Wear greatly improves user experience.
Customization of sound quality and codecs
The quality of playback depends not only on the speakers of the headphones, but also on the selected compression codec. Android allows you to force the codec to choose, but this feature is hidden in the menu for developers. To activate this mode, go to About phone and quickly click on the build number 7 times (MIUI version).
Once the developer mode is activated, a new option will appear in the settings menu for Additional → For Developers. Find the Bluetooth Audio Codec section. Here you will see a list of codecs supported by your smartphone and connected headphones. Choosing a more advanced codec (for example, aptX HD) can greatly improve the detail of the sound.
However, trade-offs are worth remembering: High audio quality requires more channel bandwidth, which can lead to sound and video being desynchronized in games or movies. If you notice audio delay, go back to the settings and select the SBC or AAC codec that provides better synchronization.
💡
Choosing a codec is a balance between sound quality and connection stability; for calls and videos, it is better to use AAC/SBC, and for music in silence – aptX/LDAC.
Solution and resetting of connection
Even with the right setup, there can be technical failures: the sound is interrupted, only one earbud is running or the device is not being detected.The first step should always be to remove the device from the paired list.Tap the gear next to the headphone name in the Bluetooth menu and select Disable or Forget the device.
If simple reconnection doesn't work, reset your network on your smartphone. Go to Settings → Connection and Sharing → Reset Wi-Fi, cellular networks and Bluetooth. This action will return network settings to factory settings, but won't delete your personal data, photos or apps. After rebooting your phone, try pairing again.
Often, the problem is the overflowing memory of the Bluetooth cache, which can be cleaned through the application menu: find the system process "Bluetooth" in the list, go to the storage and click Clear cache. This is a secure operation that often solves the "hangover" connection problem.
