Modern smartphones of the brand Xiaomi, running on the operating system Android, offer users ample opportunities for multimedia. However, the process of pairing peripheral devices can sometimes be difficult for beginners or when changing headset models. Incorrect setting can lead to desynchronization of sound and image or an unstable connection.
In this detailed guide, we will walk through all the steps of connecting wireless speakers to your gadget. You will learn not only about basic menu actions, but also about hidden developer settings that allow you to unlock the potential of high-quality codecs. We will also touch on safety and energy consumption issues.
Follow the instructions carefully to avoid common mistakes. The correct configuration of the communication interface guarantees stable operation of the device throughout the day without unnecessary connection interruptions.
Preparing devices for pairing
Before starting the procedure, you must make sure that both devices are ready for interaction. Charge your smartphone to a level of at least 50% so that the process is not interrupted due to battery drain. This is a critical step that is often overlooked. wireless headphones and smartphone to a level of at least 50%, so that the process is not interrupted due to battery drain. This is a critical step that is often overlooked.
Activate discovery mode on your headset. For most models, this is done by holding the power button or dedicated pairing button for a long time until the indicator starts flashing blue or red-blue. In the case of completely wireless models (TWS), it is often necessary to remove both headphones from the case and hold the touch zones.
⚠️ Attention: Some headphone models automatically exit pairing mode after 2-3 minutes of inactivity. If the phone does not find the device right away, repeat the procedure for activating the search mode again.
On the smartphone Xiaomi make sure that the module Bluetooth is turned on. Swipe down from the top of the screen to open the Quick Access Toolbar and tap the corresponding icon. Hold your finger on the icon to go to the advanced settings menu. Here you will see a list of available devices.
If the indicator on the headphones blinks quickly, but the phone does not see them, try turning off Wi-Fi on your smartphone. In rare cases, 2.4 GHz frequencies interfere with each other.
Step-by-step guide for connecting to MIUI
The shell interface MIUI or HyperOS may differ slightly in different versions, but the logic of operation remains the same. Go to section Settings → Bluetooth. The system will automatically begin scanning the airwaves in search of compatible gadgets.
As soon as the name of your headset appears in the “Available devices” list, click on it. A request to confirm pairing or enter PIN codemay appear on the smartphone screen. The standard code is usually 0000 or 1234, however, modern devices often bypass this step by using a secure protocol SSP.
- 📱 Make sure the smartphone screen is unlocked during the search.
- 🎧 Keep the headphones no more than 1 meter away from the phone.
- 🔄 If the device has already been paired before, click on the gear next to the name and select “Cancel pairing.”
- 🔋 Check if the power saving mode is activated, which may limit the operation of the radio modules.
After a successful connection, the status will change to “Connected”, and the headset icon will appear in the status bar. The audio stream will now be redirected to the external device. If sound continues to come through the phone's speaker, check the audio output settings in a specific application.
☑️ Connection checklist
Setting sound quality and codecs
For true audio connoisseurs, standard settings may not be enough. Smartphones Xiaomi support various audio codecs that affect bitrate and signal delay. By default, the system chooses a balance between quality and stability, often using a codec SBC.
To change the parameters, you must activate the developer menu. Go to Settings → About phone and quickly click 7 times on the “MIUI Version” or “OS Version” item. After this, a new section will appear in the advanced settings "For developers".
Inside this menu, find the subsection "Audio" or "Bluetooth Audio Codec". Here you can manually select the protocol supported by your headset:
| Codec | Sound quality | Latency (ms) | Compatibility |
|---|---|---|---|
| SBC | Basic | 220+ | All devices |
| AAC | Good | 150-200 | iOS, Android |
| aptX | High | 100-150 | Qualcomm |
| LDAC | Hi-Res | 200+ | Sony, flagships |
Codec selection LDAC or aptX HD will allow you to convey the maximum amount of detail in your music, but this may increase battery consumption and sensitivity to interference. Experiment with the settings to find the perfect balance for your use case.
What is absolute volume?
This feature synchronizes the volume control of your phone and headphones. If you notice that the sound is too quiet even at maximum, try disabling this option in the developer menu.
Fixing problems with audio latency (Latency)
One of the common complaints from users when watching a video or playing a game is the desynchronization of the picture and sound. This phenomenon is called latency. Under normal conditions, a delay of 150-200 ms is unnoticeable for music, but in games it is critical.
Many modern models Xiaomi are equipped with a special gaming mode for Bluetooth devices. To activate it, go to the application Settings → Bluetooth, click on the settings icon next to the connected headphones and find the “Low latency mode” or “Game mode” switch.
⚠️ Attention: Enabling low latency mode may automatically switch the codec to a lower quality one (for example, from aptX HD to basic SBC) for the sake of data transfer speed.
If the software settings are not enough, the problem may lie in overload of the communication channel. Try to remove sources of interference, such as a running microwave or router, that are in the immediate vicinity. Also close background applications that actively use the network.
Minimum latency is critical for gaming, so sacrifice bitrate for responsiveness. For music, high quality data transmission should remain a priority.
Power consumption and auto-shutdown management
Wireless connection is one of the main consumers of energy. To extend the battery life of your smartphone, the system Android can automatically disable unused modules. However, sometimes this feature is too aggressive, cutting off the connection to the headphones when the music is paused.
Check your battery optimization settings. Go to Settings → Applications → Application management, find the Bluetooth system process (or Bluetooth services) and in the "Energy Saving" section, select the "No restrictions" mode. This will prevent the system from “putting to sleep” the communication module.
It is also worth paying attention to the settings of the headphones themselves. Many manufacturers provide automatic shutdown after 5-10 minutes of inactivity. This function is regulated either through the headset’s proprietary application or by a combination of buttons on the body. Disabling this feature is useful if you take frequent breaks from listening.
- 🔋 Use desktop widgets to quickly monitor the charge level of accessories.
- ⚡ Avoid using cheap cables to charge the case, they may not correctly determine the charge level.
- 📶 Update the headphone firmware through the manufacturer's application to correct energy management errors.
Advanced settings and configuration reset
Sometimes it happens that the device connects, but there is no sound or does not work correctly even after all the settings. In such situations, a complete reset of network settings helps. This action will delete all saved Bluetooth pairings, Wi-Fi settings and mobile networks, returning them to factory settings.
To perform a reset, go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action and restart your phone. After turning it on, you will need to re-enter passwords for Wi-Fi networks and reconnect the headset.
If the problem persists, there may be a conflict at the driver or hardware level. In this case, it is worth checking for system updates in the About the phone → MIUI versionsection. Manufacturers regularly release patches that correct the stability of wireless interfaces.
⚠️ Attention: Resetting network settings will not delete your personal files, photos or applications. However, it will forget all saved Wi-Fi passwords, so make sure you remember them before starting the procedure.
In extreme cases, when all else fails, you may need to reset the headphones themselves to factory settings. This is usually done by holding the Volume and Power buttons for 10-15 seconds until the indicator color changes. It is better to look for exact instructions for your model in the official user manual.
Before performing a full network reset, take a screenshot of important Bluetooth settings, such as device names or special configurations, in order to quickly restore them later.
Why does the phone not see the headphones, although they are turned on?
Most likely, the headphones are not entered pairing mode. The indicator should flash in a specific way (often quickly or in two colors). Also check if they are currently connected to another device, for example, a tablet or laptop, since many models do not allow you to connect to two sources simultaneously without Multipoint support.
How to improve the quality of calls via Bluetooth on Xiaomi?
The quality of calls depends on the microphone and profile HFP. Try turning off noise reduction in your phone settings if it doesn't work correctly. Make sure the microphone on the headphones is not covered by clothing or hair. In some cases, switching the codec to SBChelps, since it is the most stable for voice communication.
Is it possible to connect two pairs of headphones to one Xiaomi phone?
Yes, many modern models support the Dual Audio function. To do this, connect the first headset, then select the second one in the Bluetooth menu and click “Connect”. The sound will be broadcast to both devices simultaneously. This feature is available in the notification shade or in the advanced Bluetooth settings.
What should you do if the sound is interrupted when you walk?
Interruptions are often caused by obstacles between the phone and the headphones. The human body does not transmit Bluetooth radio signals well. Try placing your phone in your chest pocket or in your hand on the headphone side. Also check if there are cases with metal inserts that shield the signal.
How to disable voice prompts when connected?
Voice notifications (“Bluetooth connected”, “Power on”) are part of the firmware of the headphones themselves and are usually not disabled through the phone settings. However, in some proprietary applications (for example Mi Buds or third-party applications) there is an option to disable the voice assistant or system sounds.
