Modern users rarely do without wireless speakers, and the Xiaomi ecosystem offers some of the most affordable and functional solutions on the market. The process of creating a pair between a headset and a smartphone usually takes less than a minute, but sometimes hides nuances that are not written about in short manuals. Understanding the principles of operation data transfer protocol will help you avoid typical mistakes during the first start.
Before you begin active actions, you need to make sure that both devices are ready for operation. This applies not only to battery charge, but also to the correct operation of communication modules in the operating system. In this article, we will analyze in detail the entire algorithm of actions, from removing headphones from the case to fine-tuning audio codecs for maximum sound quality. Owners of devices or wired models with a Bluetooth adapter often encounter situations when the phone does not see the accessory. Sometimes the reason is trivial, for example, a forgotten protective film insulator on the contacts of the case. In other cases, a more in-depth diagnosis of Android settings is required.
Device owners Mi True Wireless or wired models with a Bluetooth adapter often encounter situations where the phone does not see the accessory. Sometimes the reason is trivial, for example, a forgotten protective film insulator on the contacts of the case. In other cases, a more in-depth diagnosis of Android settings is required.
Primary preparation of equipment and checking the charge
The first step should always be a visual inspection and check of power consumption. If you have just unpacked new Xiaomi Earbuds, pay attention to the presence of transparent stickers on the charging contacts inside the case. They must be removed, otherwise the device will not be able to charge and enter pairing mode.
Make sure that the smartphone has the communication module turned on. To do this, lower the notification shade and find the corresponding icon. If it is gray, the function is deactivated and device search is not possible. Turn on geolocationas in modern versions of Android (starting from 6.0) this is a security requirement for the operation of the Bluetooth scanner.
⚠️ Attention: If the indicator on the case flashes red or does not light up at all when the cable is connected, check the cable and power supply. Using too powerful chargers for laptops sometimes causes a conflict between power controllers in cheap accessories.
Charge both devices to at least 30-40%. Low battery power can cause the headphones to enter power saving mode and stop broadcasting their presence signal. This is a common problem with models Redmi Buds early generations.
If the headphones have been lying idle for a long time, leave them in the charging case for 30-40 minutes before turning them on for the first time to “wake up” the lithium-polymer battery.
Activating pairing mode on Xiaomi headphones
The algorithm for switching the headset to detection mode depends on the specific model. Most truly wireless headphones (TWS) enter this mode automatically upon removal from the case the first time they are used. If you connect them to a new phone, a forced reset or manual start.
For models with a touch button on the case body (for example, Mi True Wireless Earphones 2), you need to open the cover and press the function button on the back or front panel. Hold it for 2-3 seconds until the indicator starts flashing white quickly. This is a signal that visibility mode is activated.
- 🎧 Standard procedure: remove both headphones from the case and wait for synchronization between them (usually one of the indicators blinks).
- 🔘 Manual start: press and hold the touch area on both headphones simultaneously for 5 seconds.
- 🔄 Reset settings: if the device does not respond, place them in the case, close the lid and hold the reset button for 10 seconds until the indicator color changes.
In wired ones Xiaomi Bluetooth headsets, such as Mi Sport Bluetooth, pairing mode is often activated automatically when turned on for the first time. If the device has previously been paired with another phone, you may need to hold the power button for a long time (about 7 seconds) until the “Pairing” voice notification appears.
☑️ Checking readiness for pairing
Search and connect through the Android settings
After the accessory has switched to visibility mode, pick up the smartphone. Go to the main menu and select Settings. Find the section responsible for wireless connections. In the MIUI or HyperOS shell, it is usually called Bluetooth and is located at the top of the list or in the "Connection and Sharing" group.
In the menu that opens, make sure that the activation slider is set to the "On" position. The system will begin automatically searching for available devices within range. This process may take from 5 to 15 seconds. The name of your model should appear in the "Available devices" list, for example, Mi True Wireless EBs Basic.
Click on the device name. At this point, a request to confirm pairing with the code or simply a “Connected” notification may appear on the screen. If the system requests a PIN code, the standard value for most Xiaomi devices is 0000 or 1234, although modern models do without this step.
| Headphone model | Mode indication | Connection feature |
|---|---|---|
| Mi True Wireless 2 / 2S | White flashing | Requires opening the case |
| Redmi Buds 3 / 4 | White flashing | Automatic entry when removed |
| Mi Sport Bluetooth | Blue-red flashing | Long hold of the button |
| Xiaomi Neckband | Blue flashing | Voice guidance |
If “Other devices” or a name with the postscript “LE” (Low Energy) appears in the list of available devices, try connecting to it if the main name does not respond. This is especially true for devices that support the protocol Bluetooth Low Energy.
Using the Xiaomi Earbuds application for setup
To expand the functionality and gain access to hidden sound settings, it is recommended to install a specialized application. The official application Xiaomi Earbuds (previously known as Mi True Wireless) allows you to control noise reduction, equalizer and update the firmware.
Download the application from the Google Play Store or by scanning the QR code from the instructions. Once launched, the application will automatically detect connected headphones. Click "Add Device" and follow the onscreen instructions. This will enable Adaptive Noise Cancellation and configure touch controls.
⚠️ Attention: Application functionality may vary in different regions. If your model is not detected in the application, try changing the region in the Mi Account profile settings to “China” or “India”, but remember that this may affect the operation of other services.
Inside the application you will find a section for updating the software. Check regularly for new versions firmware. Manufacturers often release patches that eliminate problems with channel desynchronization or improve connection stability.
Why update headphone firmware?
Updates often contain fixes for critical errors, improve microphone algorithms for calls, and optimize power consumption. Sometimes a new version adds support for new audio codecs, which improves sound quality.
Solving common connection problems
Even if you follow all the instructions, failures may occur. If your phone sees the device, but says “Connection error” or “Unable to pair,” try forgetting the device in the Bluetooth list and starting the process again. Often, completely clearing the list of paired devices on your smartphone helps.
Another common problem is desynchronization of the left and right headphones when the sound comes from only one channel. To solve this problem, perform a Hard Reset. This is usually done by placing the headphones in the case, opening the lid and pressing the reset button for 10-15 seconds until the indicator flashes three times.
- 📶 Interference: Make sure that there are no operating microwave ovens or powerful Wi-Fi routers nearby that can jam the signal in the 2.4 GHz range.
- 📱 Bluetooth cache: In rare cases, clearing the Bluetooth service cache in the "Applications" menu -> "Show system processes" -> "Bluetooth" -> "Memory" -> "Clear cache" helps.
- 🔋 Energy Saving: Check if your smartphone has an "Ultra-Energy Saving" mode, which may limit the operation of background services and communication modules.
If all else fails, check the compatibility of Bluetooth versions. Although the standard is backwards compatible, very old headphones (version 3.0 and lower) may not work correctly with the latest smartphones that require specific security profiles.
In 90% of cases, the problem is solved by completely resetting the headphones to factory settings and deleting the old pairing profile from the phone's memory.
Adjusting sound quality and audio codecs
After a successful connection, you should pay attention to the quality of audio transmission. In the Bluetooth settings (often hidden in the "For Developers" menu or in the headphone application), you can select priority audio codec. Xiaomi devices typically support SBC, AAC and aptX codecs.
The AAC codec provides better sound quality on iOS and Android devices, providing good compression without noticeable loss. If your headphones and smartphone support aptX Adaptive, be sure to activate this mode for minimal latency when playing games and watching videos.
In the "Settings for Developers" section (to activate, you need to click on the build number 7 times in "About phone") you can find the item "Bluetooth Audio Codec". Here you can forcefully select the desired data transfer format. However, remember that selecting an unsupported codec may result in no sound.
What to do if the sound is quiet or intermittent?
Check the absolute volume level. In some versions of Android, the volume levels of your phone and headphones are not in sync. Try turning on or off the "Absolute volume level" option in the "For Developers" menu. Also make sure that the equalizer with cut frequencies is not activated in the "Mi Music" application or other player.
Can Xiaomi headphones be connected to an iPhone?
Yes, Xiaomi fully wireless headphones work with iOS like regular Bluetooth headsets. However, the functionality of the Xiaomi Earbuds app for iOS is limited, and some functions, such as the pairing pop-up window or detailed equalizer settings, may be unavailable or unstable.
Why do headphones drain quickly after connecting?
This may be due to the use of high-definition codecs (LDAC, aptX HD), which consume more power. Active Noise Cancellation (ANC) may also be the cause. Try switching to "Normal" or "Eco" mode in the application to check.
