Modern smartphones line Redmi and Xiaomi have long ceased to be equipped with a standard 3.5-mm connector, which makes the transition to wireless headsets not just a trend, but a necessity for many users. The process of pairing devices in the Android ecosystem with the shell MIUI or HyperOS is usually intuitive, but often faces the non-obvious nuances of Bluetooth modules.
You don’t need to be a technician to successfully connect. TWS-headphones or a full-size headset with your device, but if the standard procedure doesn't work, it's important to understand what hidden settings might block the connection. In this article, we will examine not only the basic algorithm of actions, but also the specific features of Xiaomi that improve the sound quality.
The first step is always to get both devices ready to go, as chargeless gadgets can behave unpredictably while searching for networks.
Make sure your Xiaomi smartphone has a wireless module on, and the headphones themselves are in active search mode, which is usually signaled by a fast-blinking indicator.
Do not try to connect a device if it has previously been paired with another phone nearby – this can cause address conflicts and delays in audio streaming.
Bluetooth activation and device search on Redmi
Start the process by unlocking your smartphone’s screen and moving to the control center, which is called by a swipe down from the top right corner of the screen.
Click on the Bluetooth icon to activate the module, after which the system will automatically start scanning the available gadgets in range.
If automatic search does not give results, you need to go to the advanced settings menu, where you can start a forced update of the list of available devices.
- 🔍 Tap and hold the Bluetooth icon in the notification curtain for a quick transition to the menu.
- 📱 Make sure the phone is not in Do Not Disturb mode, which sometimes limits background search processes.
- 🔄 In the “Available Devices” list, find the name of your headset that usually matches the brand or model.
The MIUI shell has its own device prioritization system, so new gadgets can be displayed in a separate category “New devices”.
When you click on the headset name, the system will attempt to establish a secure connection by requesting confirmation or automatically pairing.
⚠️ Note: If you see multiple names in the list, select a device without additional characters or numbers at the end, as this often indicates the main communication channel.
Mode of pairing on headphones of different types
A critical step is to properly put the headset itself into visibility mode, as many models do not automatically enter it when turned on.
For TWS-True Wireless Stereo models often require both earbuds to be removed from the case and touch panels or hold physical buttons for a period of time. 3-5 seconds.
Full-size models may require holding the power button until the indicator flashes alternately in red and blue.
Some budget models go into pairing mode only when first enabled after purchase, requiring reset to be re-activated.
Owners of Xiaomi devices should pay attention to the speed of the indicator reaction: slow blinking usually means standby mode, and fast – readiness to connect.
If the headset has previously been used with an iPhone or other Android smartphone, it is recommended to reset the settings to the factory before a new attempt.
Step-by-step connection instructions in MIUI and HyperOS
Once both devices are ready, the algorithm becomes linear, but requires careful attention when system queries appear.
Open the Settings → Bluetooth menu and wait for your headset name to appear at the bottom of the screen in the Available Devices section.
Tap the name and a window may appear on the screen asking for a confirmation code – in 99% of cases, it is a standard combination of 0000 or 1234, or an automatic confirmation.
☑️ Checklist of successful connection
Xiaomi’s system can request permission to access contacts and call logs – this is necessary to display the caller’s name and manage calls from the headset.
After a successful connection, the status will change to “Connected”, and the headphone battery icon will appear in the notification curtain if the model supports charging level transfer.
In some cases, manual activation of A2DP (for music) and HFP (for calls) profiles is required in the optional settings menu of a particular device.
Customization of sound and codecs for Xiaomi
To get the maximum sound quality, it is not enough to simply connect devices, you need to configure the parameters of audio stream transmission in the engineering menu or through special applications.
Xiaomi supports various audio codecs such as SBC, AAC, aptX and LDAC, the choice of which directly affects bitrate and audio delay.
To check and change the codec, go to Settings → About Phone → The kernel version (7 times to log in to Developer Mode), then look for the “Bluetooth Audio Codec” section.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | High (200+ms) | All devices. |
| AAC | Good. | Medium (150 ms) | iOS, Android |
| aptX | High. | Low (40 ms) | Qualcomm chips |
| LDAC | Hi-Res | Variable | Android 8.0+ |
Using LDAC or aptX HD codec allows you to transmit sound with minimal loss, which is especially noticeable when listening to FLAC or WAV files.
However, activating high-quality codecs can increase the battery consumption of a smartphone and the headphones themselves by 10-15%.

Solving Connection and Sound Problems
Even if all instructions are followed, there may be situations where the phone sees the headphones but doesn’t connect, or the sound is interrupted and wheezing.
A common cause is a crowded Bluetooth cache on a smartphone that requires cleaning through the app menu or resetting network settings.
The problem may also lie in the interference of Wi-Fi signals, especially if the router is running at 2.4 GHz, which coincides with the Bluetooth range.
- 🗑️ Remove the device from the saved list and pair again, forgetting previous profiles.
- 📡 Turn off Wi-Fi during connection time to exclude radio interference on the air.
- 🔋 Check the charge level, as at low voltage, the Bluetooth module is unstable.
If the sound is played only in one headphone, check the balance of channels in the settings of special features or perform a complete reset of the headset.
Xiaomi owners sometimes help to disable the “Absolute Volume Level” feature in the developer menu, which solves problems with quiet sound.
⚠️ Note: If the problem persists after Network Reset, check if the antivirus or system optimizer is blocking Bluetooth services.
Additional functions and headset management
Xiaomi’s ecosystem offers enhanced management capabilities that go beyond just playing music.
When using Mi True Wireless or Redmi Buds headphones, the system automatically offers to install a proprietary application to configure the equalizer and update the firmware.
Through the Bluetooth menu, you can configure actions when you double or triple tap on the touch panel, assigning an assistant call or switching tracks.
💡
Use the Blueooth widget on the MIUI desktop for quick access to the headphone charge level and switching between devices without logging into the deep settings menus.
The “Mi Link” feature allows you to instantly connect compatible headphones simply by bringing them to an unlocked smartphone with the screen on.
Some models support simultaneous connection to two devices (Multipoint), which allows seamlessly switching between a call on the phone and a video on the tablet.
For gamers, the Game Mode feature is relevant, which minimizes sound latency by activating triple touch or through a companion app.
💡
Regular updates to the headphone firmware through the Xiaomi Earbuds app eliminates connection bugs and improves the stability of the microphone.
