Modern smartphone users Xiaomi and Redmi are increasingly abandoning wires in favor of wireless solutions that give freedom of movement and eliminate the confusion of cables. The process of pairing Android devices, particularly the shells MIUI and HyperOS, is usually as automated as possible and understandable even for beginners. However, despite the simplicity, sometimes there are nuances that require knowledge of the exact algorithm of actions for successful synchronization of gadgets.
In this article, we will discuss in detail how to properly put your headphones in detection mode, find them in the smartphone menu and adjust them for comfortable listening to music or calls. We will also touch on important technical aspects, such as codec selection and power management, which is especially important for owners of Xiaomi devices. Follow our recommendations to enjoy quality sound without delays and connection breaks.
To begin with, we'll prepare both devices for interaction, because successful connectivity depends on the right sequence of actions. It's important to understand that standard Bluetooth headphones and active noise cancelling models can have their own peculiarities in activating mating mode.
Preparation of wireless headphones for pairing
The first and most important step is to put your headphones in visibility mode for external devices. Many users make the mistake of simply turning on the device, not realizing that the first connection requires a special Pairing Mode. Without this, the Xiaomi smartphone will simply not see the headset in the list of available devices, and the search will continue indefinitely.
For classic overhead or intrachannel models with a single control button, it is usually required to press the on button for 5-7 seconds until the indicator starts flashing alternating colors (most often blue and red). In the case of fully wireless models of TWS (True Wireless Stereo), the algorithm may differ: it is often necessary to remove both headphones from the case and pinch the touch zones or mechanical buttons on the headphones themselves.
⚠️ Warning: If the headphone indicator flashes slowly in one color (usually blue), this means reconnecting to the last device, not search mode.
Make sure the headphones have enough charge, as they consume more power in active search mode. If the device is new, you may need to remove the protective film from the charging contacts inside the case to activate the battery before starting use.
Bluetooth enabled and device search on Xiaomi Redmi
Once the headset has gone into detection mode, you need to activate the corresponding module on the smartphone. Xiaomi owners have quick access through the control panel: just swipe the notification curtain from top to bottom and click on the Bluetooth icon. However, for the initial setup, you better go to the full system menu.
Open the Settings app and find the Bluetooth partition. Make sure the switch is activated. The system will automatically start scanning the surrounding space. The "Available Devices" list should show the name of your headset. If you see a device but it's not connecting, it may already be connected to another gadget.
- 📱 Check that the smartphone screen displays the exact name of the headphone model.
- 🔍 Make sure the distance between the Redmi phone and the headset is not more than 1-2 meters.
- 🔄 If the device is not found, try turning off and back on Bluetooth on your smartphone.
In some cases, especially with budget headphone models, input may be required. PIN-The standard combinations are usually 0000 or 1234. MIUI Usually requests confirmation automatically, and you just need to click OK or Connect in the pop-up window.
Connection process and communication confirmation
When you click on the device name in the list, the process of establishing a secure communication channel begins. On the smartphone screen, a pairing request will appear, where the profile of the device (audio, headset, media) can be displayed. Press the Connect button and wait for the audible signal in the headphones to confirm success.
After a successful connection, the status in the menu will change to "Connected", and next to the battery icon, the headphone charge indicator can appear (if the model supports the transfer of this setting), now sound from all applications, including YouTube, Spotify and system notifications, will be transmitted to the external headset.
It is important to note that some advanced headphone models support multipoint (simultaneous connection to two devices).If you plan to use a headset with a Xiaomi phone and, for example, a laptop at the same time, check the support for this feature in the instruction, as it is activated often by a specific combination of buttons.
☑️ Checking a successful connection
Customization of sound and additional functions in MIUI
MIUI and HyperOS offer advanced audio customization options. Going to the Bluetooth menu, click the arrow next to the name of the connected headphones. Here you can manage permissions: enable access to contacts and call logs to see the caller's name and be able to drop calls with buttons on the headset.
Xiaomi smartphones support various audio compression formats, such as SBC, AAC, aptX or LDAC. Choosing a better codec (if supported by both headphones and a phone) will significantly improve the detail of music.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | Tall. | All devices. |
| AAC | Good. | Medium | iOS, Android |
| aptX | High. | Low. | Android (Qualcomm) |
| LDAC | Hi-Res | Different. | Flagships Sony, Xiaomi |
Also available on this menu is often auto-response settings and voice assistant control. If you want to automatically translate the sound to your headphones when you call, without having to press the receive button, make sure that the appropriate switch is activated.
💡
To minimize the delay of sound in games, turn on the Game mode in the Security app -> Accelerate Games and select your headphones there as a priority device.
Solution: Headphones don't connect or lose touch
Despite the stability of Bluetooth 5.0 and higher used in modern Redmi, there are occasional crashes. If the phone sees the device but says "failed to connect," try resetting the network settings. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
⚠️ Note: Resetting your network settings will delete all stored Wi-Fi passwords and Bluetooth pairs. Use this method only if other methods have not helped.
A common problem is profile conflict. In the menu of the connected device (arrow to the right of the name), try to disable the Multimedia profile and then turn it on again. This will restart the audio stream. Also check if the Power Saving mode for Bluetooth is activated, which can limit the background operation of the headset.
If the sound is interrupted or there is a crack, make sure there are no powerful sources of interference, such as a running microwave or a router running at 2.4 GHz. In rare cases, cleaning the cache of the Bluetooth service through the developer menu helps.
- 🗑️ Remove the device from the list of coupled and connect again.
- 📶 Reboot Xiaomi smartphone to reset communication module errors.
- 🔋 Check the charge of the headphones - at a low energy level, the signal power drops.
Use of engineering menus and hidden settings
For advanced users who want to make the most of Xiaomi + Bluetooth headset, there is an engineering menu available. To get there, open the Phone app and type ##6484## (to log in to CIT) or use the MIUI Debugger app. However, beware: changing the wrong settings can lead to unstable work.
In the standard developer settings (to activate, you need to 7 times click on the build number in About Phone), you can find the Bluetooth Audio Codec. Here you can force the codec to choose if you do not like the automatic selection of the system, and there you can adjust the bitrate and sampling frequency.
How to reset TWS headphones to factory settings?
Remember that updating the firmware of the headphones themselves (if the manufacturer provides such an application, for example, Xiaomi Earbuds or Galaxy Wearable) can fix connection bugs. Check regularly for updates in the relevant apps from Google Play.
Optimizing energy consumption and stability
MIUI is known for aggressive battery optimization, which sometimes kills background Bluetooth headset processes. To keep the headphones running smoothly, find the Bluetooth app (often called simply "Bluetooth" or "System Processes") in the battery settings and set "No Limits" mode.
This will prevent audio from being turned off when you lock your screen or switch to other heavy apps, and it’s also worth turning off the “Run in the background” option for rarely used audio services so that they don’t conflict with the main stream of music.
💡
The stability of Bluetooth on Xiaomi depends on the power saving settings. Disabling the restrictions for Bluetooth system services is the key to avoiding breaks.
Following these guidelines, you can ensure a high-quality and seamless connection between your Redmi smartphone and any wireless headphones. Proper codec configuration and permission management will make using the gadget as comfortable as possible.
