Owners of Redmi and Xiaomi smartphones are often faced with the need to quickly and efficiently connect external audio devices. Wireless headsets offer freedom of movement and no tangled wires, but the initial setup process can be confusing for newbies. Modern devices based on MIUI or HyperOS offer advanced sound control capabilities that are hidden deep in the system menus.
The correct synchronization device with a phone is only the first step to high-quality listening to music or comfortable conversations. It is important not only to find a gadget in the list, but also to optimize data transfer parameters to minimize delays and maximize audio clarity. In this material, we will analyze in detail all the stages from enabling the search mode to fine-tuning codecs.
Regardless of whether you use proprietary Xiaomi Buds or third-party models from Sony or JBL, the basic principles of connection remain the same for the entire Android ecosystem. However, there are nuances specific to the Redmi shell that allow you to unleash the full potential of the acoustics. Let's get started with the step-by-step setup of your equipment.
Preparing the headphones and smartphone for pairing
Before starting the procedure, make sure that both devices have sufficient battery power. Low energy levels may result in an unstable connection or interruption of the search process. For a Redmi smartphone, it is recommended to have at least 20% charge, while the headphones must be fully ready for use.
The key point is to put the headset into mode visibility. Most models require you to hold down the power button or a dedicated pairing key for 5-7 seconds until the light starts flashing quickly (usually blue or white-blue). Without this action, the phone will not be able to detect the device on the air.
On the smartphone side, you must activate the communication module. Go to Settings and select section Bluetooth. Make sure the switch is in the active position. The system will automatically start scanning the area around you.
⚠️ Attention: If your headphones were previously connected to another phone, they may automatically try to connect to it, ignoring the new Redmi. In this case, temporarily disable Bluetooth on your old device or reset the headset.
MIUI sometimes hides advanced settings under additional menus. If the standard search does not immediately produce results, try updating the list of devices by clicking on the update icon or simply turning Bluetooth off and on again. This clears the cache of previous search queries.
☑️ Ready to connect
Search and initial connection process
As soon as the communication module is activated, a list of available devices will appear at the bottom of the screen. Find your model name in the list. It may match the brand or be a unique identifier specified in the instructions, for example, TWS Pro or Headset X.
Click on the device name to initiate the pairing procedure. A request to confirm pairing using a special code may appear on the smartphone screen. In most modern cases, this stage occurs automatically without user intervention, but sometimes you need to enter 0000 or 1234.
A successful connection is accompanied by a characteristic sound signal in the headphones and a status change in the phone menu to “Connected”. Now the device is ready to transfer media content and phone calls by default.
It is worth noting that some models support the function multipointthat allows you to simultaneously communicate with two sound sources. If your headset has this option, connecting to Redmi will not break the connection with your laptop or tablet if they have already been paired previously.
Setting the profile and sound settings in MIUI
After a successful connection, the system prompts you to configure the way you use the device. In the Bluetooth settings window, by clicking on the gear next to the name of the connected headset, you will see profile switches. Typically this is “Media Audio” for music and “Calls” for phone conversations.
It is important for Redmi users to know about the function Absolute volume level. If you notice that the volume on your phone and headphones are adjusted out of sync, try changing this setting in the developer menu or Accessibility. This will combine the adjustment sliders into a single system.
Owners of the Xiaomi ecosystem may encounter a pop-up animation window when connecting branded accessories. This is not just a beautiful picture, but an indicator of the charge level of each earbud individually. For third-party devices, this function is not available, and charge control is carried out only through the standard Bluetooth menu.
If the sound seems too quiet even at maximum volume, check if the “Hearing Safety” mode is activated in the sound settings, which artificially limits the maximum power of the speaker.
You can also rename the device in this section for convenience. This is especially useful if you have several similar gadgets. Simply click on the pencil icon or name to enter a new name, which will be displayed in the list.
Using the developer menu to improve quality
For advanced users who want to get the most out of their wireless connection, there is a hidden settings section. To access it, you need to activate developer mode. Go to Settings → About phone and quickly click on the item Version MIUI (or OS version) about 7-10 times until the activation notification appears.
Now a new item has appeared in the main settings Advanced → For developers. Scroll down to the Network or Bluetooth section. Here you will find the parameter Bluetooth audio codec. By default, the system selects SBC, which provides basic quality.
If your headphones and smartphone support more advanced standards, such as aptX, aptX HD or LDAC, you can force the selection them in this menu. This will significantly increase the bitrate of the transmitted sound, making it more detailed and rich.
| Codec | Bitrate (kbit/s) | Sound quality | Latency |
|---|---|---|---|
| SBC | 328 | Basic | Low |
| aptX | 352 | CD quality | Average |
| aptX HD | 576 | High (Hi-Res) | Average |
| LDAC | 990 | Premium | High |
⚠️ Attention: Choosing a codec with a high bitrate (for example, LDAC) can increase the battery consumption of the smartphone and the headphones themselves, as well as cause desynchronization of audio and video in some applications.
Available in the same menu “Disable absolute volume level” option. Experiment with this switch if you encounter problems with audio control. Sometimes disabling it resolves conflicts between the headset's hardware buttons and the Android software interface.
What to do if the required codec is not displayed?
If there is no aptX or LDAC codec in the developer's list, this means that either your Redmi smartphone does not support this technology in hardware, or the connected headphones are not compatible with it. In this case, the system automatically uses the best available option, usually AAC or SBC.
Solving problems with connection and signal stability
Wireless technology is sensitive to interference. If you experience audio interruptions or frequent connection dropouts, try removing sources of interference. Wi-Fi routers operating at a frequency of 2.4 GHz, microwave ovens and other Bluetooth devices can create “noise” on the air.
A frequent problem is the accumulation of errors in the pairing profile. If the headphones stop connecting or are not working correctly, remove the device. Go to the Bluetooth settings, click on the gear next to the name of the headset and select Cancel pairing or Forget device.
After this, you need to perform a full reset on the headphones themselves. This is usually done by holding the control buttons for 10-15 seconds while in or out of the case (depending on the model). Then repeat the search procedure from the very beginning.
In 90% of cases, unstable operation is solved by completely deleting the device profile from the phone's memory and re-pairing from scratch.
Also check if the power saving mode is turned on on your smartphone. Aggressive battery optimization on Redmi can limit the operation of background Bluetooth processes, which leads to the headset turning off when the screen is off.
Frequently asked questions and additional settings
Many users are interested in the ability to customize control gestures. On Redmi smartphones, this function is often integrated into the application Xiaomi Earbuds for branded models or available through third-party utilities such as Button Mapper for other brands. This allows you to reassign actions by double or triple tap.
The issue of sound delay (latency) is especially relevant for gamers. In the Bluetooth settings of some Redmi models, there is a separate switch for “Low Latency Mode” or “Game Mode”. Activating it prioritizes the transmission speed of data packets at the expense of sound quality, which is critical for shooters and rhythm games.
Do not forget to regularly update the firmware of the headphones themselves. Manufacturers release updates that fix connection bugs and improve noise reduction. You can check for updates in the manufacturer's application or in the system menu if the headset is part of the Xiaomi ecosystem.
Why do the headphones connect, but there is no sound?
Most often the problem lies in the choice of sound output profile. Make sure that the “Media Audio” switch is activated in the Bluetooth settings next to the device. Also check if a different audio output is selected in the player (for example, a phone speaker) and if the volume is set to minimum.
How to connect two pairs of headphones to one Redmi?
The Dual Audio function is not supported by all models. If your smartphone running Android 10 or higher has this option, you can connect a second device through the Bluetooth menu without disconnecting the first one. The sound will be broadcast to both headsets simultaneously.
The headphones quickly discharge after connection, what is the reason?
This may be due to the use of high-definition codecs (LDAC/aptX HD) or a malfunction of the battery of the accessory itself. Try switching the codec to SBC or AAC in the developer menu and check if the battery life changes.
Is it possible to use the headset for calls if the call profile is disabled?
No, if the “Calls” item is unchecked in the Bluetooth settings of the device, the sound of telephone conversations will go through the smartphone speaker, even if the music continues to play in the headphones. It is necessary to activate both profiles for full functionality.
How to reset network settings on Redmi if nothing helps?
As a last resort, you can reset Wi-Fi, mobile data and Bluetooth settings. This will delete all saved networks and devices. Path: Settings → Connection and sharing → Reset Wi-Fi, cellular networks and Bluetooth.
