Modern smartphones like the Xiaomi Redmi 8 Note offer users not only powerful hardware, but also advanced multimedia capabilities that cannot be fully unlocked without high-quality sound. The switch to wireless headsets relieves wire confusion and gives freedom of movement, which is especially true during sports or public transport. However, the first experience of pairing devices can raise questions, especially if you have previously used models with a 3.5 mm connector.
The process of connecting Bluetooth headphones to the Android-based MIUI shell in the Redmi 8 Note is optimized for maximum simplicity, but requires adherence to a certain sequence of actions. The system automatically scans the airwaves and offers convenient interfaces to manage connected devices. In this article, we will take a detailed look at each step so that you can enjoy your favorite music without delays and interruptions.
It's worth noting that the stability of the connection is directly dependent on the battery charge of the headset and the absence of interference in range. For successful initial pairing, make sure that the headphones are in detection mode, not just on. Let's move on to the practical part of setting up your device.
Preparing a wireless headset for pairing
Before you look for a device in your smartphone settings, you need to put the headphones themselves in visibility mode. Most TWS (True Wireless Stereo) models and classic Bluetooth headsets have a special activation algorithm, and if the headphones are new, they often go into this mode automatically when they are first removed from the case or turned on.
If the device has been used before, manual activation may be required, usually by pressing the touchpad or physical button on the case for 5-7 seconds until the light flashes blue and red (or another color specified in the manual), which is when the Bluetooth module becomes visible to external scanners.
Remember that some models require both headphones to be removed from the charging case to activate the mode (pairing).If you pull out just one headphone, it may try to connect to the latest device rather than becoming visible to your Redmi 8 Note.
⚠️ Note: Do not keep your finger on the switch button too long after the indicator flashes, as some models have long retention (more than the previous one). 10-15 seconds) results in resetting or switching off the device rather than pairing mode.
Check the headset before starting the procedure. Low charge can cause the headphones to be unstable in detection mode or interrupt the connection immediately after connection. The optimal level to start work is at least 20-30%.
Setting up Bluetooth interface in MIUI
After preparing the headset, we move to the settings of the smartphone. On the Xiaomi Redmi 8 Note, wireless interface management is brought to the top menu, but full functionality is only available in deep system settings. Open the notification curtain with a swipe from top to bottom and make sure that the Bluetooth icon is activated (burns in blue).
To make it more precise, tap and hold your finger on the Bluetooth icon to go to the corresponding menu. Here you will see a list of available devices. If the list is empty, click the Device Search button or just update the page with a swipe. Android will start scanning the ether.
It’s important to make sure your phone isn’t in “In-Air” mode, which blocks all wireless data transfers, and check if “Invisible for Other Devices” is enabled if you want other gadgets to connect to your phone, although you don’t need to connect your headphones to your phone.
The MIUI interface may offer additional settings such as "Device Name." The default phone is called "Redmi 8 Note," but you can change that name to easily identify your phone in the list of connected headphone devices if you have multiple.
Process of connecting and pairing devices
When the name of your headset appears on the smartphone screen (for example, AirDots, JBL, Sony, click on it. The system will request a pairing confirmation. In some cases, you may need to enter PIN-The code is usually standard: 0000 or 1234. Modern devices often do without this step using secure pairing.
Once the connection is successful, the Connected status will appear in the list of devices, with the profile type (media-audio, phone calls) and the sound from the phone will be broadcast to the wireless headset, and you can check the work by running any track or video.
☑️ Checklist of successful connection
If the connection is successful, the notification curtain will display the appropriate icon, as well as a widget with the level of charge of the headphones (for original accessories Xiaomi and some other brands), which allows you to control the remaining time without having to open the application.
⚠️ Warning: If you try to connect, you see an error called “Unconnected” or “Pair Failure”, try to remove the device from the list (the “Forget Device” function) and repeat the search procedure again, pre-rebooting the Bluetooth module.
Managing audio profiles and codecs
Xiaomi Redmi 8 Note supports various audio codecs that affect sound quality and power consumption. In advanced Bluetooth settings (often hidden in the “Developers” menu or in a special app for headphones), you can choose the priority codec: SBC, AAC or aptX.
The SBC codec is basic and supported by all devices, delivering stable but medium-quality audio. AAC is better optimized for Apple devices and some Android smartphones, offering better lossless compression. If your headphones support aptX, you'll get high-resolution sound, but make sure the headset also supports this standard.
| Codec | Sound quality | Stability | Energy consumption |
|---|---|---|---|
| SBC | Basic | Tall. | Low. |
| AAC | Good. | Medium | Average. |
| aptX | High (HD) | Depends on the interference. | High. |
| LDAC | Premium | Low (long distance) | Maximum. |
For normal music listening in transport or podcasts, standard settings are enough, but audiophiles may want to experiment with the settings in the developer menu to find a balance between quality and range.

Solving Connection Problems
Despite the simplicity of the technology, users sometimes face difficulties. One of the common problems is that the phone sees the headphones, but does not connect, this may be due to the fact that the headset is already connected to another device (tablet, laptop) and automatically reconnects to it, in which case you need to turn off Bluetooth on all other gadgets in range.
Another reason could be a crowded list of paired devices: Bluetooth memory on the phone is not rubbery, and if you've previously connected dozens of devices, old records may conflict, and it's recommended that unused profiles be removed from the list.
- 📱 Make sure the distance between the phone and the headphones does not exceed 1-2 metre-long.
- 🔋 Check if the headphone battery is not discharged to zero (sometimes required) 10-15 charge-minute).
- 🔄 Reboot your smartphone as a temporary failure of Android system services can block the module.
If the sound is interrupted or there is a crack, you may be in a zone of severe radio interference (near a Wi-Fi router, microwave or crowded place). Try changing the position of the phone in your pocket or removing obstacles between you and the headset.
Customization of sound effects and equalizer
Once connected successfully, it makes sense to customize the output to your preferences. Xiaomi Redmi 8 Note has a powerful audio processor built in. Go to Settings → Sound and Vibration → Sound Effects. Here you can choose the equalizer: Rock, Pop, Jazz or adjust the frequencies manually.
Mi Sound Enhancer is also available, which adapts the sound to the type of headphones used. Select "Hearphones" or "Intra-Hearphones" in the list so that the system applies the appropriate frequency adjustment.
💡
For maximum sound quality, turn off the Absolute Volume feature in the developer menu if you notice that the volume on the headphones and phone is adjustable independently and in sync.
Remember that some apps (Spotify, YouTube Music, Yandex.Music) have their own built-in equalizers, and it is recommended to either use system settings or app settings to avoid double-processing of sound, which can lead to distortions.
Optimizing energy consumption and stability
Wireless connection consumes battery life of both the phone and the headset. To extend the life of the Redmi 8 Note, turn off Bluetooth when it is not in use, and you can also limit the background work of applications that constantly access audio services.
MIUI aggressively manages energy and can kill background music player processes. To keep the music from stopping on its own, go to Security → Permissions → Auto Start and allow your player to work. Also, select No Limits mode for a particular application in the battery settings.
⚠️ Warning: Avoid using your phone for navigation or heavy gaming with Bluetooth headphones connected if your phone’s battery is less than 15% drained, as the combined CPU and radio load can cause the device to suddenly shut down.
Regularly update the firmware of the headphones themselves through branded applications from manufacturers (e.g. Galaxy Wearable for Samsung, Sony Headphones Connect for Sony). Updates often contain pairing bug fixes and improve connection stability.
