Modern smartphones like the popular Xiaomi Redmi Note 8 Pro offer users advanced multimedia capabilities that cannot be imagined without a high-quality acoustic system. Wireless headphones have become an essential attribute of an active lifestyle, allowing you to enjoy music or talk without tangled wires. However, the process of primary synchronization of devices can sometimes cause difficulties for inexperienced users, especially given the features of the MIUI shell.
In this guide, we will take a detailed look at all the steps in pairing gadgets, from activating the communication module to fine-tuning audio codecs. You will learn how to properly put the headset into detection mode, which is often a key point that is overlooked. In addition, we will touch on the issues of connection stability and ways to eliminate common errors that can occur during operation.
The smart Bluetooth connection setup on the Redmi Note 8 Pro will not only ensure stable audio transmission, but also unlock the potential of the built-in DAC device. It is important to understand that every accessory manufacturer can use its own encryption and data protocols. So there is no universal algorithm, but there are basic principles for working with the MIUI interface that apply in most cases.
Preparing a wireless headset for pairing
Before looking for a device in your smartphone settings, you need to make sure your headphones are in the correct mode.Most models require a Pairing Mode switch, which is different from normal on.If you just turn on the headphones, they can try to automatically connect to a previously familiar phone, ignoring requests from your Xiaomi.
For models with a case (like AirPods or Galaxy Buds), it is often enough to open the charger case lid without removing the headphones themselves, and to pinch the function button on the back or inside of the case. The indicator should start flashing, usually in white or blue, signaling readiness for detection. In some cases, you need to hold the touch panels on the headphones themselves for 5-7 seconds.
⚠️ Warning: If the light flashes red or goes out quickly, it is possible that the battery is critically low.Put your headphones on charge before starting the procedure, as in search mode the power consumption of the Bluetooth module increases significantly.
Make sure the headphones are no more than 1-2 meters away from the Redmi Note 8 Pro. Obstacles in the form of walls or metal objects can weaken the signal during the initial handshake stage. It is also recommended to turn off Bluetooth on other nearby devices to avoid address conflicts.
Activation of Bluetooth interface in MIUI
The MIUI-enabled Android operating system provides quick access to wireless network settings. The easiest way to activate the communication module is to use the control panel. Swipe down the screen to open the notification curtain and find the Bluetooth logo icon. Click on it to illuminate it in blue, which means activate the module.
However, for a deeper setup and guaranteed search for all devices, you’d better go to the full settings menu. To do this, open the Settings app and select the Bluetooth section. Here you’ll see the switch at the top of the screen, and once activated, the system will automatically search for available devices within range.
Importantly, the Xiaomi Redmi Note 8 Pro uses Bluetooth 5.0, which provides high data rate and low power consumption. In the same menu, you can see a list of previously connected gadgets. If your headphones are on the list but not connected, try clicking on the gear icon next to the device name and select the option to Disable or Forget the device to start the process again.
💡
To speed up your search for new devices in the Bluetooth menu, click on the three dots in the top right corner and make sure the “Visibility for all devices” option is enabled.
The process of synchronizing devices
Once the communication module is activated and the headphones are switched to search mode, a list of available gadgets should appear on the smartphone screen. The device name usually corresponds to the headphone model or manufacturer's brand (for example, JBL Tune, Sony WH, etc.). Find the desired name in the list of "Available devices" and touch it with your finger.
The system can request confirmation to create a pair. In some cases, the confirmation code will appear on the screen, which must be matched with a voice message in the headphones or simply press “OK.” The connection process takes from 3 to 10 seconds. Successful connection is accompanied by a characteristic audible signal in the headphones and the appearance of the status “Connected” in the menu of the smartphone.
☑️ Checklist of successful connection
If the connection is successful, a small headphone symbol will appear in the status bar (near the battery icon), which means that the entire audio stream is now redirected to an external device. You can run any music track or video to check the system's performance. If there is no sound, check the volume level, since on Android, the media volume and the volume of the Bluetooth device can be adjusted separately.
Advanced audio codec settings
For users who value high audio quality, the Xiaomi Redmi Note 8 Pro offers access to the Bluetooth engineering menu. Here you can choose a audio transmission codec that directly affects signal detail and delay. The standard codec is SBC, which provides a basic quality that is compatible with all devices.
To change the settings, go to the menu of the connected device (clicking on the gear next to the headphone name).If your headphones support more advanced codecs such as aptX, aptX HD or LDAC, you can select them at the appropriate point, this is especially true for listening to Lossless music or when using a smartphone for games where minimal latency is important.
⚠️ Note: Use of high-resolution codecs (e.g, LDAC) It can increase the battery consumption of your smartphone and the headphones themselves. If you notice a quick discharge, go back to the standard codec. SBC or AAC.
The codec change is instantaneous, but it can require a short-term connection break. Not all tracks in streaming services support high bitrate, so the difference in quality may not always be noticeable. Experiment with settings to find a balance between sound quality and connection stability in your particular case.

Table of codecs and their characteristics
Understanding the differences between compression formats will help you to optimally customize the sound to a specific music genre or task. Below is a comparative table of the main codecs supported by the Android platform and your smartphone chipset.
| Codec | Bitrate (kbit/s) | Delay (MS) | Best application |
|---|---|---|---|
| SBC | 328 | 200-250 | Basic audition, podcasts |
| AAC | 256 | 150-200 | iOS devices, streaming music |
| aptX | 352 | 80-120 | Android, Balance of Quality and Speed |
| LDAC | 990 | 150-200 | Hi-Res audio, critical listening |
Choosing the right codec is especially important if you use headphones for gaming. High latency in SBC or LDAC codecs can lead to desynchronization of sound and image in games, in which cases, priority should be given to protocols with low latency, even at the expense of maximum bitrate.
Solving Common Connection Problems
Despite the standardization of technology, users often face situations where the Redmi Note 8 Pro does not see the headphones or the connection is constantly interrupted.One of the common reasons is a crowded Bluetooth cache. To clean up accumulated errors, you can use a network reset, but a milder method is to clean the cache of the Bluetooth system application through the application menu.
Problems can also arise from signal interference: If you are in a place with a large concentration of Wi-Fi routers or other radiation sources (such as a microwave), try to move. The 2.4 GHz frequency range used by Bluetooth is often overloaded in apartment buildings.
💡
If the headphones are visible but not connected, try removing them from the Forgotten Devices list on your phone and restarting your smartphone before trying again.
In some cases, resetting the headphones themselves to factory settings helps, usually by pressing the control buttons 10-15 seconds before the color changes, and then resetting the search and connection procedure, just like with a new device, eliminates software conflicts that have arisen in previous pairings.
Optimizing energy consumption and stability
The constant operation of the Bluetooth module can affect the autonomy of the Xiaomi Redmi Note 8 Pro. The MIUI system has aggressive energy saving algorithms that can forcibly turn off background processes, including connecting to headphones if the smartphone screen is turned off. To avoid this, find the “Activity Control” section in the battery settings and set the “No Limits” mode for application players (Spotify, YouTube, Yandex.Music).
Also, you should keep an eye out for firmware updates on the headphones themselves, with many manufacturers releasing updates that fix compatibility bugs with various smartphone models, and the update usually comes through the headphone manufacturer's proprietary app, which you need to install from Google Play.
⚠️ Warning: Do not let the headphone battery “to zero” during prolonged storage.This can lead to a deep discharge of the lithium-ion battery, after which the device will stop turning on and connecting via Bluetooth.
Regular cleaning of the charging contacts on the case and the headphones themselves also contributes to stable operation. Oxidation of the contacts can lead to the fact that one of the headphones (usually the right or left, depending on the design) will not charge and, accordingly, will not be able to maintain a stable connection with the main module.
