Modern smartphones line Xiaomi Redmi equipped with advanced wireless communication modules that allow you to instantly create an audio system with any Bluetooth gadget. the process of pairing the device with the headset usually takes no more than a minute, but owners often face nuances associated with versions of the operating system MIUI or the features of specific models of headphones.
Understanding the basics of how a radio channel works will help avoid common mistakes when a phone doesn’t see an accessory or the connection is constantly interrupted. In this article, we will discuss the entire algorithm of actions, from putting the accessory into search mode to fine-tuning the codecs for maximum sound quality.
The correct initial setup ensures stable operation in the future, allowing the device to automatically restore communication when leaving range or disconnecting the connection, which is especially important for those who use the smartphone while moving or while playing sports.
Preparing a Bluetooth headset for pairing
Before trying to find a device in a smartphone menu, you need to make sure the headset itself is in the right condition.Most models require a forced transfer to detection mode, especially if they are connecting to a new gadget for the first time.
For fully wireless models (TWS), it is usually enough to remove both earphones from the charging case. If the indicators do not start flashing blue or white-blue, it may be necessary to keep the touch zones or mechanical buttons on the cases for a long time.
- 🎧 Remove both headphones from the case and remove protective films from charging contacts.
- 🔋 Make sure the battery level is at least 20% for a stable signal.
- 🔘 Press the function button on the case or hold the sensors. 5-7 seconds before the color change of the indicator.
- 📱 Make sure the headset is not actively connected to another phone or tablet nearby.
If the device has previously been used with another phone, it is best to reset settings to clear the list of paired gadgets.
💡
If the indicator on the headphones flashes red, then the charge level is critically low - put them in the case for 10-15 minutes before trying to connect.
Search and activate Bluetooth on Xiaomi Redmi
The MIUI shell interface offers two main ways to activate the wireless module, and the fastest method is to use the control panel, which is called by a swipe down from the top of the screen.
In the extended curtain menu, you need to find the Bluetooth icon and click on it, but to fully search for devices, this is not enough: you need to pinch your finger on this icon or go to the full settings of the system.
An alternative route is through the main settings menu, where you get access to advanced functionality, including visibility for other gadgets and managing connection history.
☑️ Activation algorithm
In the settings section, make sure the switch is in the active position. The system can request confirmation of geolocation, since in modern versions of Android this resolution is necessary for correct scanning of peripherals.
⚠️ Note: Do not leave Bluetooth on permanently in public areas with the device’s name open, as this can become a vector for Bluejacking attacks, although the risk for ordinary users is minimal.
Process of connecting and pairing devices
Once you activate the search, the smartphone will start scanning the airwaves, and the name of your headset should appear on the list of available devices, and it can match the model, the brand, or be standard, for example, TWS_i12 or Redmi Buds.
Click on the device name in the list, and you can see a request to confirm the pairing of the code, or just a notification of the connection, at which point the encryption keys are exchanged between the gadgets.
If the connection is successful, the status bar will display a headphone battery icon or connection symbol, and the voice assistant can confirm the sound from the media player will automatically switch to the external accessory.
| Status of indicator | Significance of state | User action |
|---|---|---|
| Slow blinking (blue) | Standby/search mode | You can connect from the phone. |
| Fast flashing (red/blue) | Interconnection mode | Search on the Bluetooth list |
| It's burning all the time. | Active compound | We can use it. |
| Blinks red. | Low charge. | Requires charging |
In some cases, the system may request permission to access contacts and call logs, which is necessary so that you can see the name of the caller and control through the headset buttons.
Sound setting and additional MIUI functions
Xiaomi’s ecosystem offers advanced audio management capabilities. For native models like Mi True Wireless Earbuds or Redmi Buds, the system often offers automatic plug-in installation or pop-up with animations and the charge level of each headphone separately.
For third-party devices, settings are available in the Bluetooth menu. By clicking on the gear next to the name of the connected device, you can change the usage profile. Music, Games (to reduce latency) and Conversation modes are available.
Special attention should be paid to the configuration of codecs. In the "Developer" menu (if included) or in advanced audio settings, you can choose the priority codec: SBC, AAC, aptX or LDAC. The choice depends on the standards supported by the headset.
How to Enable Developer Menu to Access Codecs
The Mi Sound function or equalizer in the Music app can also affect the final sound, and it is recommended that you calibrate the sound profile to a specific headphone model for the best bass response.
Solving problems with detection and connection
The situation when Xiaomi smartphone does not see the headphones is one of the most common, and often the problem lies not in the breakdown, but in a software failure or busy communication channel.
First, try "forget" the device. Go to the list of conjugated gadgets, click on the name of your headset and select "Delete" or "Forget." After that, repeat the search procedure from the beginning.
- 🔄 Reboot your smartphone to reset temporary network errors.
- 📡 Turn off Wi-Fi (2.4GHz band) as it can interfere with Bluetooth signal.
- 🔌 Clear the Bluetooth app cache through application settings (show system processes).
- 🔌 Check if the headset is connected to another device that is within a radius of 10 meters.
If nothing works, a complete network reset may be required, which will delete all stored Wi-Fi passwords and Bluetooth pairings, but often resolves complex driver conflicts.
⚠️ Note: When you reset your network settings, you will lose all saved passwords from Wi-Fi networks, so make sure you remember the data to access your home Internet.
Optimization of work and energy saving
The aggressive MIUI energy saving system can sometimes limit the background operation of Bluetooth services, which leads to connection breaks when the screen is off, and to avoid this, you need to configure autostart and battery.
Go to the battery settings, find the Bluetooth process or a specific application (like a player), and set the background activity limit to "No Limits" mode, which will allow the system to not "kill" the audio transmission process.
It is also worth checking whether Do Not Disturb or Sleep mode is enabled, which can block notifications and sound transmission, and for stable gaming performance, it is recommended to activate Game Mode via the Security or Game Turbo app.
💡
Connection stability depends on your energy saving settings – let Bluetooth work in the background without restrictions for your headphone model.
Regular firmware updates of the headphones themselves (via manufacturers’ proprietary apps, if any) also improve connection stability and fix known compatibility bugs with Qualcomm or MediaTek chipsets used in Redmi.
