Modern smartphones of the Redmi and Xiaomi line are created to work in a single ecosystem, where accessories like TWS-Headphones play a key role in the multimedia user experience, and the process of connecting devices usually takes place automatically and instantly, but sometimes users are faced with the need to manually adjust or eliminate pairing errors. Understanding the mechanics of Bluetooth in the shell MIUI HyperOS will help you avoid unnecessary actions.
In this article, we will take a look at all the steps of connection, from initial activation to fine-tuning audio codecs for maximum sound quality. You will learn how to correctly translate the headset into search mode, what to do if the phone does not see the device, and how to reset the headphones to factory. Information is relevant for all current models, including the AirDots series, Redmi Buds and Mi True Wireless.
Before you start, make sure your smartphone has a wireless module on and the battery is strong enough to run smoothly. Often the problem is that one of the devices is in power saving mode or has a critically low charge. Let's look at the standard algorithm, which works 95% of the time.
Preparation of devices for the first pairing
The first step should always be to check the battery status on both your smartphone and your headphone case. Devices with a discharged battery may not work properly in detection mode or interrupt the connection immediately after installation. Put the headphones in the charging case and make sure the indicators signal the charging process or full charge.
Next, you need to activate pairing mode on the headphones themselves. In most Xiaomi and Redmi models, it is enough to simply remove both headphones from the case at the same time. If this is the first turn on, they will automatically go into search mode, as the fast flashing indicator will tell you. Importantly, models with touch buttons sometimes require to hold the touch zone for 3-5 seconds before the search indication appears.
On the Redmi side of the smartphone, you need to open the swipe control panel from top to bottom and make sure the Bluetooth icon is blue. If the icon is grey, click on it to activate. The system will immediately start scanning available devices in range, which is usually up to 10 meters without obstacles.
☑️ Connection readiness
Step-by-step connection instruction through settings
Once you activate the accessory search mode, go to the main settings menu of your Redmi phone. Find Settings → Bluetooth or use the quick access via the notification bar. The Available Devices list should show the name of your model, for example, Redmi Buds 3 Pro or Mi True Wireless Earbuds Basic 2.
Click on the device name in the list. On the screen of the smartphone, you may see a request to confirm pairing or enter PIN-In modern versions. MIUI If the system requests the code, type in 0000 or 1234, although this is rarely required for original Xiaomi products.
Once you've successfully connected, the headphone battery icon will appear in the status bar, and the voice assistant can say "Connected." Now the audio stream will switch from the phone speaker to the headset, and you can check the work by running any music track or video.
💡
If two identical names appear on the list of devices (for example, L and R), remove them both, put the headphones in the case, close the lid and repeat the procedure again, removing both headphones at the same time.
Use the fast connection function of Xiaomi
Owners of Redmi and Xiaomi smartphones with MIUI 12 and higher can use the Quick Pop-Up feature, which allows you to connect headphones without going to the settings menu, similar to how it works with AirPods on iPhone.
Just open the charge case cover with the headphones inside and hold it close to the smartphone screen. The display should show an animated window with the case image and the percentage of charge of each earpiece. Press the plug-in button in this window, and pairing will go away automatically.
If the pop-up doesn't appear, check your Bluetooth settings. Go to Settings → Bluetooth → Settings (cog or three dots in the corner) and make sure the "Show pop-up for headphones" switch is active. Also, this feature may not work if the headphones were previously paired with another device and automatically connected to it.
Why isn't the pop-up window working?
Customization of sound and control through the application
To unlock the full potential of your wireless headphones, it is recommended to install the branded Xiaomi Earbuds app (or Mi Buds M8 for new models).This interface provides advanced settings that cannot be changed through the phone's standard menu.
The app has touch control settings, equalizers, and noise reduction mode choices, so you can set up actions to double, triple or long-term sensor retention, and you can also set up Game Mode, which reduces latency, which is critical for mobile shooter fans.
Special attention should be paid to setting up the equalizer, pre-installed profiles allow you to adapt the sound to different genres of music, and the application often provides a search function for headphones, which makes them emit a loud signal if you lost them at home.
| Model headphones | Application for setting | Support for ANC | Working hours (with case) |
|---|---|---|---|
| Redmi Buds 4 Pro | Xiaomi Earbuds | Yes (up to 43 dB) | 36 hours |
| Mi True Wireless 2 | Xiaomi Earbuds | Yeah (hybrid) | 28 hours |
| Redmi AirDots 3 | Xiaomi Earbuds | No. | 30 hours |
| Buds 3T Pro | Xiaomi Earbuds | Yes (up to 40 dB) | 30 hours |
Problem Solving: The phone can't see headphones
Redmi not detecting Xiaomi headphones is a common occurrence and often solved by simply resetting Bluetooth settings. Try Forgetting the device in the Bluetooth menu if it is there, and then restart the smartphone. This will clear the cache of wireless services.
If the problem persists, you need to perform a full reset (Hard Reset) of the headphones themselves. For different models, the procedure is different: usually you need to place the headphones in the case, open the lid and hold the function button on the case for 10-15 seconds until the indicator flashes in orange. In models without a button on the case, you need to simultaneously hold the sensors of both headphones for 5-7 seconds.
⚠️ Warning: After resetting, the headphones can automatically connect to another device (tablet or laptop) that was paired before.Switch off Bluetooth on all other gadgets within range before re-searching.
It’s also worth checking if the phone has Do Not Disturb mode or special audio profiles that can block audio output to external devices, sometimes switching the Bluetooth codec to the developer menu if you use advanced settings helps.
💡
90% of connection problems are solved by completely resetting headphones to factory settings and cleaning the list of conjugated devices in the phone’s memory.
Features of connecting to different versions of MIUI and HyperOS
Bluetooth interfaces and algorithms may vary depending on the operating system version. In older versions of MIUI (based on Android 10 and below), the pairing process is more conservative and requires manual confirmation. Newer versions of HyperOS and MIUI 14/15 offer more aggressive power saving, which sometimes leads to a connection break.
The new shells have a feature called "LDAC Audio Codec" or "LHDC" that needs to be activated manually in Bluetooth settings to get high-resolution sound, but it's worth remembering that this increases battery consumption. It's better to use a standard SBC or AAC codec for calls, as they provide better compatibility and stability of communication.
HyperOS users should pay attention to desktop widgets that allow you to control the charge level of the headphones without opening applications. If the widget does not display data, try to remove the device from Bluetooth and connect it again, allowing all requests for access to data that will appear on the screen.
⚠️ Note: When upgrading your phone firmware to a new version of Android or MIUI Old connection profiles may become incorrect, and it is recommended to delete old (pairing) before major system updates.
Stability also depends on background processes. If you have a lot of Bluetooth-monitoring apps installed (like fitness trackers or smart homes), try temporarily disabling them to avoid priority conflicts when connecting an audio device.
