Modern smartphones Xiaomi Redmi line offer excellent sound quality, but to fully use the capabilities of multimedia often requires a wireless headset. the process of connecting the device to the accessory may seem difficult only at first glance, but the system MIUI or HyperOS greatly simplify this procedure.
In this article, we will discuss in detail the algorithm of actions that will help you establish a stable connection between the gadget and the headphones. You will learn about the intricacies of the data protocol, the features of codecs and how to eliminate typical errors. The right sequence of actions will save your time and nerves.
Before you go into action, make sure your device is running a wireless module. This is a basic requirement without which further manipulations do not make sense. Also check the battery level of the headset, as the discharged device may not appear in the list of available.
Preparation of devices for pairing
The first step is to put the headphones in detection mode. Most models require a power button or a special pairing button to be pressed 5-7 seconds before the indicator flashes. This process may differ from manufacturer to manufacturer: Sony often uses a separate button, and JBL may require you to turn on when the volume key is pressed. Carefully read the instructions for your accessory.
On the side of the Xiaomi Redmi smartphone, visibility needs to be activated. Android's default hides the device from prying eyes for security reasons, but when you open the settings menu, it becomes searchable. Make sure the phone's screen is unlocked, as some versions of the MIUI shell restrict the search for new devices on a locked screen.
⚠️ Warning: If the headphone indicator flashes red and blue (or flashes white quickly), it is a regular search mode. If only red is on, the device is discharged or simply on, but not ready for (conjugation).
It is important to keep the devices close to each other during the first attempt of connection, the distance should not exceed one meter to avoid loss of data packets when shaking hands, the presence of metal barriers or working microwave ovens can create interference in the 2.4 GHz range.
💡
If the headphones have previously been connected to another phone, they may automatically try to connect to it.Switch off Bluetooth on the old device before you start setting up the new one.
Step-by-step connection instruction through settings
The main method of activating communication is in the system menu. You need to open Settings and select Bluetooth. In some versions of the firmware, this section is in the Connect and Sharing group. Switch the slider to the active position if it is not already lit blue.
Once turned on, automatic scanning of the airwaves will begin. The list of available devices will be updated in real time. Find in the list the name of your model, which usually corresponds to the brand or series, for example, AirDots or Galaxy Buds. Click on the line with the name to initiate the process.
☑️ Connection algorithm
The system can request confirmation of the access code. Most often the code is universal (0000 or 1234), but modern Bluetooth LE protocols often do not do this step, requiring only the consent of the user.
| Action. | Expected system response | Waiting time |
|---|---|---|
| Incorporation of the module | The appearance of the Bluetooth logo in the curtain | 1-2 seconds |
| Searching for devices | Rotating search indicator | 5-10 seconds |
| Request for pairing | A pop-up with a code | Instantly. |
| Communications installation | "Connected" status | 2-5 seconds |
Use of the Mi Connect widget and quick menu
The MIUI shell provides accelerated access to Bluetooth functions through the Control Center. Swipe down from the top right corner of the screen (or up from the bottom, depending on the navigation settings) to open the curtain. Long-term tapping on the Bluetooth icon will open an extended menu where you can quickly select a previously used device.
Xiaomi ecosystem users can access Mi Connect (formerly known as MIUI Pop-up) and when you open a headphone case next to your phone, you automatically display animations with battery life and a connection button, which only works with certified Redmi and Mi devices.
If the automatic window does not appear, check for updates for the Mi Connect plugin in the GetApps app store. The function can also be disabled in Bluetooth settings. TWS headsets owners will appreciate the ease of displaying the charge of each headphone separately right on the desktop.
Customization of sound and codecs in the engineering menu
For advanced users, you can set the audio transmission settings. By default, the system chooses the optimal codec, but sometimes manual intervention is required to improve quality or stability. Go to Settings → Bluetooth, click on the gear next to the connected device.
You can choose the priority codec: SBC (basic), AAC (standard for Apple and many Android), aptX or LDAC (high resolution). The choice depends on the support of a particular headphone model. Using the LDAC codec requires high data transfer speeds and can consume the battery faster.
⚠️ Warning: Forced activation of a codec that is not supported by the headset will result in no sound or strong wheezing. Change settings only if you are sure of compatibility.
Also available in this menu is the "Absolute Volume" setting. If the volume of the phone and headphones is out of sync (for example, at the maximum of the phone is quiet, and at the minimum loud), try to switch this setting. This synchronizes the software and hardware volume levels.
Solution: if the headphones are not
It's not uncommon for a Xiaomi phone to not see the headset. Often the problem lies in the Bluetooth service cache. Go to Settings → Apps → All apps, click three dots in the corner and select Show System Processes. Find the Bluetooth process and click Clear → Clear Everything.
Another reason could be profile conflicts: If the headphones were previously connected to this phone but are not working properly, click Remove or Forget the device in the list of conjugated gadgets.
Check if flight mode or power saving is on, which may limit the operation of communication modules. In some cases, resetting network settings helps, but it will also delete stored Wi-Fi passwords. Use this method only if other methods did not help.

Features of connection TWS-headset
True Wireless Stereo headphones are synchronized with each other. Make sure that both earbuds can see each other before connecting to your phone. Usually, you have to take them out of the case at the same time and wait for one of them (the host) to find the other (the follower).
The problem of channel desynchronization (when the sound is only in one ear) is solved by completely resetting the headset, which often requires clamping the touch panels of both headphones for 10-20 seconds before changing the color of the indicator, after resetting the phone, you need to remove the device from the list and perform the pairing again.
Xiaomi Redmi owners can use the Mi Buds app (or built-in settings for their models) to update the headphone firmware.This is critical to fix connection bugs.The update is via Bluetooth, so keep the case charged at least 50% during the process.
💡
Stability of work TWS-Headsets 90% depends on the relevance of their internal firmware and the purity of charging contacts in the case.
