Modern smartphones like the Xiaomi Redmi Note 8 Pro are equipped with advanced wireless modules that allow easy management of multimedia. However, the process of primary synchronization of accessories sometimes raises questions for users, especially when working with new models of headsets.
Owners of MIUI-based devices may encounter nuances that distinguish their experience from that of pure Android.The system has its own characteristics of managing power consumption and connection priorities.Understanding these mechanisms will avoid common mistakes and quickly enjoy your favorite music without delay.
In this guide, we will take a detailed look at each step of pairing, from activating the module to fine-tuning the codecs, how to eliminate interference and what to do if the device can’t see the headphones, and following the algorithm ensures that the task is successfully completed even for inexperienced users.
Preparation of smartphones and accessories for work
Before the pairing procedure begins, you need to make sure that both devices are ready to interact. Battery charge plays a critical role: at low charge, the system can limit the power of the transmitter to save energy. This often leads to unstable connection or inability to detect the gadget.
Turn on your Redmi Note 8 Pro and unlock the screen. Make sure the headphones also have a charge, especially if they are completely discharged during storage. Some wireless headsets go into deep sleep and require a long network connection to activate.
⚠️ Attention: If the headphones have previously been paired with another phone, they may automatically try to connect to it by ignoring your smartphone.
It is important to check the physical condition of the devices, the absence of visible damage to the antenna modules and the purity of contacts (in case of a case) contribute to stable operation, and it is also worth removing old, unused profiles from the phone's memory to make room for a new connection.
Activation of Bluetooth module in MIUI system
To get started, you need to activate the radio module through the system menu, and the fastest way is to swipe the notification curtain down from the top, find the Bluetooth icon and press it to light up in blue, and that will trigger the detection service.
The deeper settings are available through the main settings menu. Go to Settings → Bluetooth. Here you will see the switch at the top of the screen. Once activated, the phone will start scanning the surrounding space for available devices.
This menu also shows the name of your smartphone that other gadgets see, and can be changed if necessary by clicking on the appropriate line, which is useful if you often connect to public audio systems or want to personalize your device.
MIUI also offers a feature called "All Device Visibility" that should be active at the time of search, which is automatically enabled by default when you open a menu, but sometimes requires manual verification, especially after firmware updates.
Transfer of headphones to pairing mode
The key is to properly switch the headset to search mode. Most modern models, including the TWS (True Wireless Stereo), switch to this mode automatically when first removed from the charging case, the indicators begin to flash, signaling readiness for the device.
If automatic connection does not occur, you need to use a mechanical method. On full-size models or neck headsets, you usually need to press the on button or a special pairing button for 5-7 seconds.
- 🎧 For TWS Headphones: remove both headphones from the case at the same time and wait for the flashing of indicators.
- 🔘 For overhead models: press the power button before the voice "Pairing" or flashing lamps appear.
- 📱 For gaming headsets: a mode switch to the "Mobile" position may be required or"BT" before activating the search.
Some specific models require reset before you first connect. Device-specific instructions are always a priority source of information. If standard methods don't work, try looking for a Reset button on the case or inside the case.
⚠️ Warning: Don't keep your headphones too far from your phone while pairing. 30-50 centimeters for stable protocol.
The process of connecting and authorizing the device
Once both devices are in search mode, they should find each other. On the Redmi Note 8 Pro screen, the name of your headset will appear on the list of available devices. Click on it to begin the pairing procedure.
The system can request confirmation of the access code. In most modern cases, the code is not required and the connection is established automatically, however, for older models or specific profiles, you may need to enter a combination, usually 0000 or 1234.
When you connect, you may be asked to allow access to contacts and call logs, which is necessary for the headset to function as a hands-free device, and the denial of access will limit the functionality to media playback.
☑️ Checking a successful connection
Once the procedure is completed, the status bar will have an icon and the Bluetooth menu will have the device "Connected" status, and the audio stream will now be switched from the phone speaker to external acoustics.
Customization of sound quality and codecs
Xiaomi Redmi Note 8 Pro supports various audio codecs that affect the quality of signal transmission. Standard is SBC, but for high quality it is worth activating AAC or aptX if your headset supports them.
To access hidden audio settings, activate the developer menu. Go to Settings → About Phone and quickly click on MIUI Version seven times. Once the developer mode activation message appears, go back to the main settings menu.
In the section Additional → For developers, scroll down to the "Network" block. Here are the Bluetooth settings. Find the "Bluetooth Audio Codec" item and select the most suitable option from the list of available ones.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | Tall. | Universal. |
| AAC | Good. | Medium | iOS, Android |
| aptX | High. | Low. | Qualcomm chips |
| LDAC | Hi-Res | Variable | Sony, flagships |
What if the selected codec is not on the list?
Experiment with settings to find a balance between sound quality and connection stability. In a noisy space (metro, office) simpler codecs can work more stable.
Profile and priorities management
Once connected, you can customize the behavior of the device in detail. Click on the gear icon or the arrow next to the name of the connected headphones in the Bluetooth menu. Here you can access additional profile management options.
You can prioritize different types of media, like allowing audio transmission for music and video, but turning off audio call transmission, leaving conversations on the phone speaker, which is convenient if the headset microphone is worse than the one built in.
- 📞 Phone Sound: Transmitting audio during incoming and outgoing calls.
- 🎵 Multimedia: Playing music, videos and sounds of games.
- 📢 System sounds: notifications, keyboard clicks and system allerts.
The Auto Connection feature is also available on this menu, and if it's active, the phone will try to connect to the headset when it comes within reach, and turning it off is useful for battery saving if you don't want to keep looking for the device.
💡
Rename your headphones in the Bluetooth menu (like “My Buds Pro”) to easily distinguish them from friends or colleagues on public transport.
Solving Connection Problems
Despite the simplicity of the procedure, there are occasional crashes. If the Redmi Note 8 Pro can't see the headphones, try rebooting the Bluetooth module: turn it off and turn it on again. Often this clears the scan cache and eliminates software freezes.
If the problem persists, perform Forget Device in the Bluetooth menu, which will delete all the stored encryption and profile settings, and then the pairing procedure will need to be re-conducted as with a new device.
⚠️ Note: Before resetting your network settings, make sure you know the passwords from Wi-Fi networks, as this operation can delete their saved configurations.
In rare cases, a complete network reset is required. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This is a radical method that helps with deep system errors of communication drivers.
💡
90% of connection problems are solved by simply restarting both devices or removing the old pairing profile.
Optimization of work and energy saving
To extend battery life, you should pay attention to the energy saving settings. MIUI aggressively manages the background processes. Make sure that the application through which you listen to music is not limited to the system in the background.
Go to Settings → Battery and Performance and find your music player. Set Unlimited mode. This will prevent playback from breaking when the phone screen is off.
It’s also worth turning off Bluetooth when it’s not in use for a long time, not only saving battery power, but also reducing the risk of unauthorized access or location tracking via Bluetooth beacons.
Regularly update the firmware of the headphones through the branded applications of manufacturers (for example, Xiaomi Earbuds, Galaxy Wearable, etc.). Updates often contain fixes for connection stability and microphone improvements.
