Modern smartphones Xiaomi Redmi series almost completely devoid of 3.5-mm audio jack, which makes the transition to wireless sound not just a trend, but a necessity. The process of pairing a headset with a device based on the shell MIUI or the new HyperOS usually takes seconds, but users often have difficulties with finding a device in the list or the stability of the connection. Understanding the nuances of Bluetooth protocol will help avoid common errors in the first setup.
In this article, we will discuss in detail the algorithm of actions for successful synchronization of accessories of various brands with your gadget. You will learn about the hidden features of the system that improve the quality of audio transmission, and how to troubleshoot if the standard connection does not work.
Before starting the procedure, make sure that both devices are on the wireless module. It is also important to check the battery power, as the discharged headset may not enter search mode or quickly turn off during the setup process. If you use new headphones, remember to remove special insulation films from the charging contacts, if any are in the case design.
Preparation of devices for the first pairing
The first step is to activate the detection mode on the headset itself, which most modern models automatically switch to when they first pull out of the case or when they first turn on, but if the device has been used with another phone before, you must force the search to be run so that Xiaomi Redmi can see it.
This usually requires you to pinch the touchpads or physical buttons on both headphones simultaneously for 5-10 seconds, until the indicators start flashing alternating colors (often white or blue).In some models, such as the AirPods or Galaxy Buds, you need to pinch the pairing button on the back of the charging case. Ignoring this stage is the most common reason why the phone does not see the accessory.
⚠️ Warning: Do not bring your headphones too close to a running microwave or a powerful Wi-Fi router while pairing, as radio interference can interrupt the encryption key exchange process.
On the smartphone side, it's also worth making sure that Bluetooth settings don't include "Visible only for paired devices" if you're trying to connect the gadget for the first time. The standard way to check is Settings → Bluetooth. Make sure the slider is activated and the phone scans the surrounding space. MIUI often offers accelerated pairing for ecosystem devices, but for third-party brands will require manual selection.
Step-by-step connection instruction via MIUI settings
Once the accessory is ready, we go directly to the smartphone interface. Open the settings menu and find the Bluetooth section. At the top of the screen, a list of available devices will be displayed. If your headset is in pairing mode, it should appear in the "Available Devices" list with the corresponding model name.
Tap the name of the device in the list. You can see a request to confirm the pairing of the code or just a notification about the connection, at which point you exchange profiles: A2DP for music, HFP for calls and AVRCP for playback control. The process takes from 3 to 10 seconds.
☑️ Checklist of successful connection
If the connection is successful, the headphone battery icon (for some models) or the standard headset icon will appear in the status bar. The system notifications sound should switch to the external device. In case of failure, the system will give an error message, and you will need to repeat the procedure, previously removing the device from the list of saved ones, if it is left there.
💡
To speed up the search, you can use the Bluetooth widget in the notification curtain: a long click on the icon immediately opens the full list of settings, bypassing the main menu.
Use of fast connection and widgets
Xiaomi smartphone owners can use the quick connection feature, which is built into the shell of MIUI. When you open the case cover of compatible headphones (especially brands Xiaomi, Redmi, Poco) next to the phone, an animated window automatically pops up on the smartphone screen with a suggestion to connect the device. This eliminates the need to climb into the deep settings menu.
But it doesn't work for all brands. You can set up a Bluetooth widget on your desktop for universal fast access. You can tap a blank area of the screen for a long time, select "Widgets" and drag and drop the Bluetooth control, and you can turn the module on/off and go to the list of devices with a single touch, which is especially handy if you change the audio output between the speaker and the headset often.
Newer versions of HyperOS have a device control center where you can not only connect, but also check the charge level of each headphone separately, if the data protocol supports it. To activate the extended widget, update system components through the Security application or MIUI Services.
| Type of device | Method of activating search | Indication | Waiting time |
|---|---|---|---|
| TWS (case) | Press the button on the case. | Blinking white | 5-7 seconds |
| Invoices | Long press of the power button | Blinking red and blue | 3-5 seconds |
| Necks. | Retention of the switch | Voice signal | 4-6 seconds |
| Mono | Triple press. | Fast blinking. | 2-3 seconds |
Customization of sound quality and codecs
After successful pairing, it is recommended to check the audio codec settings for the best sound quality. Xiaomi Redmi supports various compression protocols such as SBC, AAC, aptX and LDAC. The choice of codec affects bitrate and sound latency, which is critical for music and games respectively.
To change settings, go to Settings → Bluetooth, click on the arrow next to the name of the connected device. This may show the current codec. To access the developer's extended menu (if hidden), click on the build number in the About Phone section several times, and then in the Developer menu, find the Bluetooth Audio Codec and select your preferred option.
⚠️ Note: Use of high resolution codecs (LDAC, aptX HD) It consumes the battery of both headphones and smartphones much faster. SBC.
You can also configure audio sharing (if two devices are connected) or call priority. Some Redmi models allow you to configure the equalizer specifically for Bluetooth devices via the MI Sound or Dolby Atmos app, which allows you to compensate for the shortcomings of the dynamics of budget models.

Managing Multiple Devices and Profiles
Modern versions of Xiaomi-based Android allow you to hold up to 7-10 paired devices at a time, although you can actively transfer sound to only one (or two in dual audio mode).
To manage the list, go to the Bluetooth menu, click on the gear or arrow next to the device, and select "Disable" or "Forget the device." Forget completely removes the encryption keys, which is useful when selling headphones or resetting. If you use the Mi Home smart home, the headphones can automatically pause playback when a smartwatch calls.
It's important to keep priorities in mind: if you have a watch and headphones on, you can call the clock and play music with your headphones. You can set your behavior in Settings → Sound and Vibration → Advanced Sound Settings. You can also adjust the absolute volume level that synchronizes the phone and headset sliders.
💡
Automatic switching between devices works more stable if all gadgets have the same Mi Cloud account enabled and Bluetooth synchronization is activated.
Solution: Headphones are not connected or are not working stable
If Xiaomi Redmi doesn’t see headphones or communication is constantly interrupted, try resetting network settings. Go to Settings → Connection and Sharing → Reset Wi-Fi, cellular networks and Bluetooth. This action will delete all saved passwords and pairs, but often resolves software driver conflicts.
Another reason could be a crowded cache of the Bluetooth app. Go to Settings → Apps → All apps, find the “Bluetooth” list (may need to enable system processes display) and click “Clear Data.” Fear not, it won’t delete your files, only temporary connection logs.
In rare cases, the problem is energy saving. MIUI aggressively unloads the background. Go to the battery settings, find an app you're listening to music through (like Spotify or Yandex.Music), and set the energy saving mode to "No Limits," which will prevent music from crashing when the screen is off.
