Modern Xiaomi Redmi smartphones offer advanced multimedia capabilities, and wireless acoustics have become a standard of living. Lack of extra wires allows you to move freely, exercise or work without being distracted by confusing cables. However, the initial connection setup for beginners is sometimes questionable, especially given the features of the MIUI or HyperOS shell.
The process of pairing Bluetooth devices in the Android ecosystem from Xiaomi is as automated as possible and takes seconds, if you know the correct algorithm of actions. Unlike some other manufacturers, there are nuances of displaying battery power and connection priorities. It is important to understand that the stability of communication depends not only on the software settings, but also on the correct transfer of the headset itself to detection mode.
In this article, we will take a look at all the stages of connection, from activating the module in the system to fine-tuning audio codecs for Hi-Res sound. You will learn how to force switch devices, eliminate audio and video desynchronization, and what hidden features are available to owners of Redmi smartphones.
Preparing a Bluetooth headset for pairing
Before you look for a device in your smartphone settings, you need to make sure that the headset itself is ready for data transfer. TWS-The True Wireless Stereo headphones go into pairing mode automatically when they are first removed from the case, if they are new, in which case the indicators start flashing quickly, signaling readiness to connect.
If the headphones were previously used with another phone, they need to be switched to manual search mode, usually requiring the touch panels or physical buttons on the case case (or the headphones themselves) to be pressed for 5-7 seconds, and the indication will change to alternate flashing in red and blue, which is a universal signal of the visibility of the device for external gadgets.
⚠️ Warning: Make sure the headphones are not automatically connected to another nearby device (such as a tablet or laptop) that is within range. In this case, the Redmi phone may not see them because the headset is already busy.
For wired Bluetooth adapters or overhead models, the procedure is similar: long-term retention of the power button puts the device in the (pairing) mode. Only after the corresponding light signal appears, you can switch to working with the smartphone interface.
💡
If the light flashes only red, the headphone battery is critically low, so charge them before you try pairing, otherwise the connection may break during the setup process.
Activation of Bluetooth module in MIUI interface
To get started with the wireless peripherals, you need to activate the corresponding module in the operating system. In Xiaomi smartphones, this can be done in two ways: through the notification panel or through the main settings menu.
Swipe down the screen to open the Notification Curtain. Find a Bluetooth logo icon (usually a stylized "B") among the icons. If it's gray or crossed out, tap it once. The icon should light up in blue, which means the radio module is turned on and the environment is scanned.
A deeper setup is available through the system menu. Go to Settings → Bluetooth. Here you will see the switch at the top of the screen. Once activated, the phone will start searching for available devices. The same menu displays your smartphone name, which other gadgets see when trying to transfer files.
- 📱 Quick access: swipe from top to bottom and tap on the icon.
- ⚙️ Full menu: Settings → Connections → Bluetooth.
- 🔍 Visibility: Make sure the phone is visible to other devices if you need to transfer a file.
- 🔄 List Update: Pull the screen down in the Bluetooth menu for a re-search.
The process of searching and connecting the device
Once you activate a search in your smartphone menu, the name of your headset should appear in the "Available Devices" list. In MIUI, this list is updated in real time. Once you see the desired name (such as Redmi Buds, AirDots or the name of a third-party brand), click on it to initiate pairing.
The system can request confirmation of action. In some cases, especially when connected to devices without a screen or with a simple protocol, the pairing will pass automatically without input. PIN-Standard codes, if required, are usually 0000 or 1234, but modern codes are not. TWS-Models do without this stage.
Successful connectivity is accompanied by a distinctive beep in the headphones and a change in status in the phone menu, with the device name labeled "Connected" and a battery icon showing the left and right headphone charge levels separately, a signature feature of the Xiaomi ecosystem that allows you to control power without third-party apps.
☑️ Checklist of successful connection
If the connection is successful but no audio, check the media settings. Sometimes the phone only connects to the Headset profile (for calls), ignoring the Multimedia profile. To fix this, click on the gear icon or arrow next to the device name in the Bluetooth list and make sure that the Multimedia tick is active.
Advanced sound and codec settings
Owners of Redmi mid-to-high-end smartphones have access to advanced audio settings. The system allows you to select Bluetooth codecs that affect audio quality and latency. To activate these features, you often need to go to the Developer Menu, but basic settings are available in the regular interface.
Click on the gear icon next to the connected device in the Bluetooth menu, where you can configure button functionality (if supported by the headphone manufacturer) and priority use, for example, you can prohibit the use of headphones for calls, leaving them only for listening to music.
It’s important for audiophiles to know which codec is the default. Xiaomi supports modern audio compression standards. Switching between them can change the sound significantly, from saving battery power to maximum high-frequency transmission quality.
| Codec | Sound quality | Delay (MS) | Compatibility |
|---|---|---|---|
| SBC | Basic | 200-300 | All devices. |
| AAC | Good. | 150-200 | Android, iOS |
| aptX | High. | 100-150 | Flagships |
| LDAC | Hi-Res (max) | 100-200 | Top models |

Managing Multiple Devices and Priorities
The MIUI-based Android operating system allows you to store many paired devices in memory, but only one of them can be broadcasted at the same time (except in rare cases, multi-point connectivity, if supported by the headphones themselves). Priority management is carried out through the Bluetooth menu.
If you have a smartwatch and headphones connected, the phone may try to bring the notification sound to both devices. To avoid this chaos, go to the settings of each connected gadget, where you can separately turn off the media or call sound for a particular device, leaving, for example, only vibration on the watch.
When switching between devices (for example, you listened to music in your headphones, and now you want to turn it on the speaker), you don't have to turn off Bluetooth completely. It's enough to click on the play menu (in the curtain or player) to output the sound icon and select the desired active device from the list, this happens instantly and without breaking the connection.
⚠️ Warning: Simultaneously connecting to two different audio sources (multipoint) works only if this function is hardware implemented in the headphones themselves. The phone cannot broadcast sound to two different pairs of Bluetooth headphones at once without using special third-party mixer apps.
Diagnostics of problems and troubleshooting
Despite the stability of Xiaomi Redmi, sometimes there are situations when the headphones do not connect, the sound is interrupted or absent at all. The first and most effective step is to clean the list of associated devices. Find the problem device in the list, click on the gear icon or arrow and select "Cancel pairing" or "Forget device".
Then reboot your smartphone. This action clears the Bluetooth stack cache and resets the driver's temporary errors, repeat the search and connection process again, and 90% of the time, it solves the problem of protocol conflicts.
If the problem is quiet or no sound, check the absolute volume level. In some firmware versions, the volume level of the phone and headphones is adjusted separately. Make sure the volume slider is twisted to the maximum in both the system and the buttons on the headphone case.
- 🔄 Reset: Forget the device and create a pair again.
- 🔋 Charge: Check the charge level of the case and headphones.
- 📶 Interference: Get away from sources of powerful Wi-Fi signal or microwaves.
- 📱 Update: Check for system updates in the About Phone menu".
💡
The most common cause of connection problems is the accumulated cache of old pairing profiles. Completely removing the device from the phone's memory ("Forget the device") solves most software conflicts.
If there is a sound, but it is out of sync with the video (echo or lip lag effect), try to switch the codec from the developer menu (as described above) to SBC or aptX Low Latency, if your CPU and headphones support this, this will reduce the delay in audio stream transmission.
