Modern Xiaomi smartphones running on the shell of MIUI or HyperOS provide users with ample opportunities to customize the multimedia experience. Connecting wireless peripherals has become standard, but the synchronization process can vary depending on the version of the operating system and the model of the headset. Proper Bluetooth connection configuration provides not only sound transmission, but also microphone operation, control buttons and energy saving.
Device owners often face the need to switch between multiple devices or restore communication after a failure. It is important to understand that the data protocol requires correct pairing for stable operation. In this article, we will discuss in detail all the stages of connection, from activating the search mode to fine-tuning the audio codecs for maximum sound quality.
Before you start setting up, make sure your headphones are charged and in good condition. Some models require resetting before you first connect to a new gadget. Let's look at how to prepare both devices for successful pairing without unnecessary complications.
Preparation of headphones and smartphone for pairing
The first step is always to activate the search mode on the headset. Most TWS (True Wireless Stereo) models switch to this mode automatically when removed from the case, if they were not previously paired. However, reconnection often requires a forced start, which is carried out by holding the touchpad or physical button for 3-5 seconds.
On the smartphone side, Xiaomi needs to make sure that the wireless module is active. Sometimes the system can block the search for new devices to save energy or because of flight modes. Check if the flight mode is on, which completely disables all radio modules.
- 🔋 Charge headphones and case to at least 30% for stable search mode.
- 📱 Unlock the smartphone screen as some versions MIUI limit sleep-based search.
- 🔄 Disconnect Bluetooth from other nearby devices to avoid addressing conflicts.
⚠️ Warning: If the headphone light flashes too fast or doesn't light up, it's possible the device is in deep sleep mode. Try putting them in the case, close the lid and open again in 10 seconds.
For initial pairing, it is recommended to keep the headphones and phone at a distance of no more than 30-50 centimeters. Obstacles in the form of walls or metal structures can significantly weaken the signal and make it difficult to detect the gadget.
Step-by-step connection instruction via Bluetooth settings
The basic method of connecting is standard for all Android devices, but the menu interface in the Xiaomi shell has its own features. Open the Settings app and find the Bluetooth partition. In newer versions of firmware, this item is often placed at the top of the main settings menu for quick access.
Once activation slider is enabled, the available devices will be automatically scanned. Your headset should appear in the Available Devices list, and it may be branded (e.g., JBL, Sony) or modeled (e.g., AirDots, WF-1000XM4).
☑️ Connection algorithm
When you click on the device name, the system may request a pairing confirmation. In rare cases, especially for older models or specific headsets, you may need to enter PIN-The standard combinations are usually 0000 or 1234, but modern technology often does not have this step.
⚠️ Warning: Do not press the connection button several times in a row.This can create duplicate devices in the paired list, which will lead to connection errors in the future.
After a successful connection, a connected gadget icon will appear next to the device name, and the notification curtain will display the battery level of the headphones (if the model supports the transfer of this parameter), you can now run music or video content to check the work.
Use of quick menus and MIUI widgets
Xiaomi smartphone owners can use the accelerated method of connecting through the control center. Swipe down from the upper right corner of the screen (or from the bottom up, depending on the navigation settings) opens the Quick Access Panel. Here is the Bluetooth icon, which is long pressed immediately transfers to the device management menu.
Some Xiaomi and Redmi branded headphones support Google Fast Pair fast pairing technology or the proprietary MIUI Pop-up protocol. When you open a case of such headphones next to your smartphone, an animated window automatically pops up on the screen with a suggestion to connect the device, which is the most convenient way, not requiring manual search.
💡
If the pop-up doesn't appear, check if Bluetooth and geolocation are enabled. Some models require location access to activate the Quick Detection feature.
The Bluetooth menu also includes a Device Search feature that triggers deep scanning, which is useful if the headset doesn't show up in the list of recently used ones, and the system may suggest connecting the device to the Mi Account, allowing you to synchronize settings between different gadgets of the brand.
- 🚀 Use the Control Center to quickly transition to communication settings.
- 🔍 Enable geolocation to work with the functions of fast search for new devices.
- ☁️ Sign in to Mi Account to synchronize the list of conjugated gadgets.
Importantly, desktop widgets can also contain Bluetooth switches, but they only serve to turn the module on/off, not to manage the list of devices, and you still need to go to the full settings menu for detailed configuration.
Customization of sound quality and audio codecs
Once successfully connected, users often want to improve the quality of playback. Xiaomi allows you to choose your preferred audio codec in a hidden developer menu or through standard audio settings, if such an option is available for a particular model. Codecs like aptX, aptX HD, LDAC or LHDC provide high-resolution audio transmission.
To access advanced settings, go to Settings → Bluetooth, click on the arrow next to the connected device. This can display codec and bitrate information. If the options are hidden, you can activate them in the Developer Menu by finding Bluetooth Audio Codec.
What is LHDC and why is it needed?
Consider that support for advanced codecs depends on both devices. If the headphones only support SBC, then choosing LDAC in the phone settings will not work, in which case the system will automatically switch to the best common codec available.
| Codec | Bitrate (kbit/s) | Delay (MS) | Compatibility |
|---|---|---|---|
| SBC | 328 | 200-300 | Basic (all devices) |
| aptX | 352 | 150 | Qualcomm chipsets |
| LDAC | 990 | 150-200 | Sony, Android flagships |
| LHDC | 900 | < 100 | Xiaomi, Huawei, OPPO |
Changing the codec can affect battery life. Better formats require more processing power and energy to encode and decode the signal in real time. If the smartphone battery is going down too quickly, try switching to standard SBC or aptX.
Solving Connection and Sound Problems
Despite the standardization of technology, users can encounter errors. A common problem is that the phone sees the headphones but doesn't connect, or the sound is interrupted. First, try "Forget the device" in the Bluetooth menu and pair again. This clears the cache of the security keys.
If the sound is missing or only works in one headphone, check the balance settings in Settings → Sound and Vibration → Mono audio. Also make sure that the Mi Sound or Equalizer app does not select a profile that is incompatible with the current headset.
- 🔌 Clear the charging contacts on the headphones if one of them does not turn on.
- 📶 Turn off 2.4GHz Wi-Fi as it can interfere with Bluetooth signal.
- 📱 Reboot your smartphone to reset Bluetooth services that may have got stuck.
In some cases, resetting network settings helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Note that this action will remove all stored Wi-Fi passwords and pairing history, so use it with caution.
Connecting to Xiaomi’s smart home and ecosystem
Xiaomi devices are often integrated into a single smart home ecosystem. Headphones can act not only as a sound output device, but also as a control panel. Through the Mi Home app or Xiaomi Earbuds (for some models), you can customize gestures, update firmware and search for lost headphones.
To make smart home features work, make sure the app has the necessary permissions, including location access and background work, which will allow the phone to automatically switch the audio stream when a notification from a smart speaker or a call is received via Mi Home.
⚠️ Note: When updating the firmware of the headphones through the application, do not interrupt the connection and keep the screen on. Interrupting the process can lead to complete inoperability of the headset.
Integration with Google Assistant or Yandex Alice is also customized in this section. You can call the assistant for a long press of the touch zone, which makes it more convenient to control the smartphone without having to take it out of your pocket.
💡
The stability of the ecosystem depends on the relevance of Mi Home applications and Google Play system services.
