Xiaomi smartphone owners and Redmi sub-brands often face the need to use wireless peripherals to listen to music or communicate. Connecting headphones via Bluetooth is a basic feature, but in the shell of MIUI or HyperOS, this process has its nuances. Modern models such as the Redmi Note 13 or Xiaomi 14 support advanced audio transmission protocols, but require the correct initial setup.
Proper pairing of devices ensures stable connection and high audio quality. Errors at this stage can lead to interruptions of sound or inability to control volume. In this guide, we will discuss in detail the algorithm of actions that is relevant for most current models released in 2026-2026, and also consider ways to solve common problems.
To get started, make sure that both devices are charged and in close proximity to each other, the distance should not exceed one meter for initial acquaintance of gadgets, only after successful synchronization, the range can be increased to standard values.
Preparation of headphones for pairing
The first and most important step is to put the headset into detection mode, and many users mistakenly believe that simply turning the device on is enough to make it appear on the list of available smartphone networks. In fact, most TWS (True Wireless Stereo) models and overhead headphones require a forced entry into Pairing Mode.
If you use devices from Xiaomi itself, such as Mi True Wireless Earbuds, when you open a case next to an unlocked phone, an automatic pop-up often appears. However, for third-party brands such as Sony, JBL or Samsung, the procedure may be different. Usually you need to pinch the touchpad or physical button on the case for 5-7 seconds until the indicator starts flashing blue and red or flashing white quickly.
⚠️ Warning: If the light is flat or flashing slowly, the device is in normal operation and not searchable".
To work properly, it is recommended to pre-clean the list of previously connected devices on the headphones themselves, if they were previously used with another phone, which will prevent automatic connection to the old sound source and speed up the search process with the new smartphone.
How to Reset Headphones of Different Brands
Bluetooth setup in MIUI and HyperOS
Xiaomi’s operating system interface offers flexible wireless settings. To start a search, you need to open the swipe control panel down from the top right corner of the screen and activate the Bluetooth module. To access advanced settings, you need to pinch your finger on the Bluetooth icon or go to the Settings → Bluetooth menu.
This section shows all the devices available for connection within range. The system automatically scans the airwaves and sorts the gadgets found. If your device doesn't appear in the "Available Devices" list, try pressing the update button or switching the phone's visibility slider, although it's rare to connect headphones.
Importantly, newer versions of HyperOS have changed the scanner’s logic to save energy, so if the search takes too long, it makes sense to reboot the Bluetooth module itself by turning it off and turning it on in the settings menu, which resets the cache of detected devices and triggers a fresh search.
Connection and authorization process
When you find a device on the list, click on the name of the device. The system initiates a pairing request. In most cases, the confirmation is automatic, without entering the codes. PIN-The standard combinations are usually 0000 or 1234.
When you connect, the system asks for permission to access contacts and call logs, so that the names of the callers are displayed in the headphones and the history of calls is accessible through the headset, and refusing these permissions will limit the functionality to only media playback.
☑️ Checklist of successful connection
Once successfully paired, the status bar will have a special headphone battery icon (if supported) and a connection icon. The sound signal in the headset will confirm the connection. You can now run test audio to check the channels.
Advanced sound and codec settings
Smartphones Redmi and Xiaomi mid-to-high price segment support various audio compression codecs, such as SBC, AAC, aptX and LDAC. By default, the system chooses the optimal codec, but the user can force it to change the developer menu or in advanced Bluetooth settings.
To access hidden settings, you need to activate the developer mode, this is done by seven times pressing the build number in the About Phone section. Once the Developer Menu appears in the basic settings, look for the Bluetooth Audio Codec section, where you can select the priority codec.
Using an LDAC or aptX HD codec significantly improves the audio quality, making it closer to Lossless, but can increase power consumption.The standard AAC is the most stable option for iOS and Android-based devices, providing a balance between quality and autonomy.
💡
For maximum sound quality, activate the LDAC codec in the developer menu, but remember that this can reduce headphone life by up to 30%.
Solving Connection Problems
Despite standardizing protocols, users often face situations where the phone can't see the headphones or the connection is constantly breaking.One common reason is the crowded list of paired devices in the Bluetooth module's memory.The system may simply ignore new requests if the limit is reached.
Problems can also arise from software failures in Google Play Services or the Bluetooth system process, in which case it helps to clear the cache of the relevant services through the application menu or completely reset the network settings.
| Problem. | Possible cause | Decision-making |
|---|---|---|
| Headphones not found. | Pairing mode not activated | Press the button for 7+ seconds |
| Low volume. | Different volume levels | Insert "Absolute volume" in the settings |
| Persistent breaks | Wi-Fi interference 2.4 GHz | Switch router to 5 GHz |
| No sound in games. | Codec delay | Use the game mode or aptX Low Latency |
⚠️ Warning: If the problem persists after resetting Bluetooth settings, check if the antivirus or power-saving app blocks the wireless module from working.
Management and additional functions
Once successfully connected, the user has access to playback and call management. MIUI includes support for Google Assistant or Xiao AI. Double or triple touching the touch zone of the headphones is usually customized through a separate manufacturer's app, but the basic features work natively.
For gamers, sound delay is a critical parameter. In Game Turbo, the game mode built into Xiaomi smartphones, priority is given to data transfer speeds, which minimizes audio and video desynchronization. This mode is activated automatically when you start games from the list or manually through the sidebar.
💡
Using game mode in MIUI/HyperOS reduces Bluetooth audio latency, which is critical for shooters and rhythm games.
Also worth mentioning is the Mi Link feature, or similar ecosystem services that allow you to instantly switch audio streams between your phone, tablet and laptop without re-pairing, which requires you to sign in to the same Mi Account on all devices.
