The use of a wireless headset has become a standard for owners of modern smartphones, but the initial pairing process often causes difficulties for users of the ecosystem MIUI. Unlike other manufacturers, the Xiaomi shell has its own characteristics in working with Bluetooth protocols and managing peripheral devices. Understanding these nuances will allow you to avoid typical mistakes when you first start.
In this article we will analyze in detail the algorithm of actions required to activate Bluetooth connections between your phone and a headset of any type. We will look at both standard TWS models and full-size devices with active noise cancellation. We will pay special attention to troubleshooting, since problems with device visibility are a common scenario.
Before moving on to the software settings, you need to make sure that the accessory is physically ready for work. Many users forget that new devices often come with protective insulators on the contacts or require initial charging. Without first activating the battery, some models may not be detected by the smartphone even after long pairing attempts. This is a critical step, ignoring which negates all further manipulations.
Preparing equipment and activating pairing mode
The first step is always to put the headset into discovery mode. The standard procedure for most models involves holding the power button or a dedicated pairing button for a long time. On TWS (True Wireless Stereo) models, this process is often hidden inside the charging case. You will need to remove both headphones and possibly press the touch zone or physical button on the case body.
LED indication plays a key role in diagnosing the status of the device. Typically, a flashing blue or red-blue indicator indicates that it is mode (Pairing) active. If the indicator lights up steadily or does not light up at all, it means that the device is either already paired with another gadget or is discharged. In the case of Xiaomi Redmi Buds or AirDots, you often need to double-tap the sensor to force entry into the search mode.
⚠️ Attention: If your headphones were previously connected to another phone, they may automatically try to connect with it, becoming invisible to Xiaomi. Be sure to turn off Bluetooth on all previously used devices before starting setup.
The length of time you hold the button varies depending on the accessory manufacturer. For some models, 3-5 seconds are enough, others require holding for up to 10-15 seconds until a characteristic sound signal or rapid blinking appears. Owners of models JBL, Sony or Sennheiser should refer to the manual, since the operating logic of their proprietary software may differ from the standard.
If the indicator does not light up after removal from the case, wipe the metal contacts on the headphones and inside the case with a dry cotton swab - oxidation or dust may block charging and turning on.
Setting up Bluetooth in the MIUI interface
After preparing the accessory, we proceed to the smartphone settings. In the shell MIUI or HyperOS Management of wireless modules is placed in the top notification shade or in the main settings menu. For quick access, swipe down from the top right corner of the screen to open the control center. Find the Bluetooth icon and make sure the switch is activated (lit blue).
If there is no shortcut, follow the path Settings → Bluetooth. Here the system will begin automatically searching for available devices within range. It is important that the smartphone screen is unlocked, since in sleep mode, some versions of Android limit scanning of peripherals to save energy. The name of your headset should appear in the “Available devices” list.
The pairing process on Xiaomi usually takes place automatically, but sometimes confirmation of the passcode is required. If the system asks for a PIN code, the standard values are most often 0000 or 1234. However, modern protocols Bluetooth Low Energy often do without entering a code, using a secure connection SSP (Secure Simple Pairing).
It is worth noting that new versions of Xiaomi firmware have introduced the “Quick Connect” function for devices of its own brand. If you are using original Xiaomi Earbuds, the setup window may appear automatically immediately after opening the case cover next to the phone being turned on. This works similarly to Google's Fast Pair technology.
Solving problems with visibility and connection
The situation when a smartphone does not see the headset is one of the most common. The cause may be a software glitch in the Bluetooth module of the phone itself. In this case, a complete reboot of the Bluetooth stack helps. To do this, it is not necessary to reboot the entire phone, just turn off and turn on the module in the settings.
If a simple reboot does not help, you need to clear the Bluetooth service cache. This is a deeper procedure that resets temporary connection files. Go to Settings → Applications → All applications, find “Bluetooth” in the list (may be called “Bluetooth Services” or “Bluetooth MIDI”) and select “Clear data” or “Reset settings”. After this, the phone will require a reboot.
- 🔄 Restart the smartphone and headset at the same time to synchronize the search time.
- 📡 Make sure that the distance between the devices does not exceed 1 meter during pairing.
- 🔋 Check the charge level - when the charge is low, some models go into energy-saving mode and hide from searches.
⚠️ Attention: The Applications menu interface in MIUI may hide system services. To access them, turn on the display of system processes in the All Apps screen settings (usually a switch in the form of three dots or a slider in the corner).
It is also worth considering the influence of third-party applications. Various memory cleaners or antivirus apps can block the operation of the Bluetooth module, considering its activity suspicious. Try disabling such apps temporarily. If the problem persists, check to see if your phone is in airplane mode, which sometimes gets stuck in software.
☑️ Bluetooth diagnostics
Advanced sound and codec settings
After a successful connection, users often encounter low sound quality or delays in games. The Xiaomi shell allows you to control audio codecs, although access to these settings is sometimes hidden. To access the engineering menu or advanced sound settings, you can use special codes or applications, but the standard path is through the developer menu.
To activate the developer menu, go to Settings → About phone and quickly click 7 times on the “MIUI Version” item. After the message “You have become a developer” appears, return to the main settings menu, select “Advanced” → “For Developers”. Here, find the section related to Bluetooth and pay attention to the settings LDAC, aptX or AAC.
The choice of codec affects the bitrate of the transmitted audio stream. If your headset supports high resolution but the sound remains mediocre, try manually switching the codec in the developer menu. However, be aware that using high-resolution codecs (such as LDAC) increases power consumption and can lead to unstable connections in areas with a lot of radio interference.
What are aptX and LDAC?
These are audio encoding technologies that allow you to transmit audio with less quality loss compared to standard SBC. For them to work, support must be available both in the smartphone and in the headphones.
Owners of gaming smartphones of the series Black Shark or flagships Xiaomi Mi should pay attention to the game mode. It often has a function to reduce audio latency (Low Latency Mode), which forcibly changes the priorities of the Bluetooth connection in favor of data transfer speed, sacrificing the stability of the radio signal over long distances.
Comparison of popular models and compatibility
Not all wireless headphones work equally well with Android. There is a compatibility table that is based on the chipsets and Bluetooth versions used. Below is data on the typical behavior of various devices when connected to Xiaomi smartphones.
| Headphone model | Bluetooth version | Features on Xiaomi | Stability |
|---|---|---|---|
| Xiaomi Redmi Buds 3 | 5.2 | Instant pop-up window, setup via Mi Home | High |
| Apple AirPods 2/3 | 5.0 | Work like normal ones, there is no settings menu, tearing is possible | Medium |
| Sony WH-1000XM4 | 4.2 | Requires Sony Headphones application for full functionality | High |
| QCY T13 | 5.1 | Good compatibility, but requires a reset to reconnect | Medium |
As can be seen from the table, native Xiaomi devices have advantage in integration with the system. Third-party brands, such as Apple or Samsung, may work in basic mode, depriving the user of some functions, such as automatic wear detection or equalizer adjustment.
When choosing a new headset for a Xiaomi phone, it is recommended to pay attention to support for the AAC codec, since it is the de facto standard for Android and provides the best balance between quality and compatibility. The SBC codec, although supported by all devices, often produces a noticeable delay and a “metallic” sound.
Power management and background work
MIUI's aggressive power saving system often becomes the enemy of wireless accessories. The system can force close the application that controls the headphones or turn off the Bluetooth module to save battery. This leads to the headphones turning off spontaneously or stopping responding to commands.
To prevent this, you need to configure autorun and no restrictions for the relevant applications. Go to Settings → Applications → All applications, find the application for controlling the headphones (or the Bluetooth system service) and select “Battery”. Set the mode to "No restrictions". Also turn on the “Autostart” toggle switch.
- 🔋 Disable energy saving for Bluetooth services in the battery menu.
- 🚫 Do not use “Memory Cleaner” immediately after connection headset.
- 📲 Pin the headphone control application in the list of recent tasks (lock with a lock).
⚠️ Attention: Energy saving settings may vary depending on the version of MIUI (Global, China, Russia). If the described items are missing, try finding them by searching in the settings for “Battery” or “Energy Consumption.”
In addition, some users note that enabling the “Memory Expansion” (Virtual RAM) function on budget Xiaomi models may negatively affect the stability of the Bluetooth connection due to the increased load on the controller. If you experience constant disconnections, try temporarily disabling this feature in the “Advanced” settings.
Correctly setting access rights and power saving is critical for the stable operation of wireless peripherals on Android Xiaomi, since the system limits background processes by default.
Frequently asked questions (FAQ)
Why The headphones connect, but there is no sound?
Most often the problem lies in the connection profile. Once paired, click on the gear next to the device name in the Bluetooth list and make sure the Audio and Media switches are activated. Also check if the phone speaker or another device is selected as the audio output device.
How to reset the TWS settings of Xiaomi headphones?
Put both headphones in the case. Press and hold the button on the case (or the touch zones on both headphones at the same time) for 10-15 seconds until the indicator flashes orange or white three times. After that, remove the device from the Bluetooth list on your phone and pair again.
Is it possible to connect two Bluetooth devices at the same time?
The standard MIUI shell supports connecting only one pair of headphones to output sound at the same time. However, there are Dual Audio modes available on some models that allow you to broadcast audio to two different headsets, but this depends on the Bluetooth version and hardware support.
The headphones wheeze when talking, what's wrong?
When you switch to talk mode, the headset profile (HFP) is activated, which reduces the sound quality for voice transmission. If the wheezing is severe, there may be low battery or radio interference. Try to move away from radiation sources (Wi-Fi routers, microwave ovens).
How to update headphone firmware via phone?
Official Xiaomi headphones are updated via the app Mi Home or Xiaomi Earbuds. Third-party brands may require installation of their branded apps from Google Play. It is usually impossible to update the headset firmware through the standard Bluetooth menu.
