The situation when the favorite Redmi Buds or Mi True Wireless suddenly stop syncing with a smartphone, familiar to many owners of the Xiaomi ecosystem. Instead of the usual sound in the headphones, you see only a flashing indicator or a complete lack of reaction to pairing attempts. Often the problem lies not in the hardware breakdown, but in a software failure that is easy to fix.
Before you panic and bring your device to the service, it’s worth analyzing the latest steps: whether you’ve updated your Android or MIUI operating system, changed your Bluetooth settings, or maybe your headphones just went off to zero. In most cases, resetting or the right sequence of actions when pairing again solves the problem in minutes.
In this article, we will take a closer look at all possible causes, from elementary battery discharge to complex driver conflicts, and offer step-by-step instructions to restore the operability of your wireless accessories.
Main reasons for lack of connection
The first thing to do is to rule out trivial but often ignored factors. Battery discharge is the most common reason Xiaomi headphones don’t go into pairing mode. If the case or the headphones themselves were lying idle for several weeks, the lithium-ion battery could go into a deep discharge, requiring 15-20 minutes of charging before activation.
The second important aspect is the crowded list of devices in the memory of the Bluetooth module of the smartphone. If you have previously connected headphones to other gadgets and have not removed them from the list, there may be a conflict of addresses, and it is worth checking whether the phone settings are activated flight mode or energy saving, which forcibly disables wireless modules.
⚠️ Note: If the headphones have previously been paired with another device (tablet, laptop, or friend's phone), they may automatically try to connect to it when turned on, ignoring your smartphone.
Technical problems can also be caused by software errors of the HyperOS or MIUI operating system itself. After major firmware updates of the smartphone, Bluetooth stack services sometimes fail, which requires rebooting network settings or the device itself.
Diagnostics and primary inspection of devices
Start your diagnosis with visual inspection and indication check. When extracted from the case, Xiaomi headphones should give a light signal. If the indicators are silent, wipe the contact areas on the headphones and inside the case with a dry cotton swab. Oxidation or dust often blocks the transfer of energy.
Check the Bluetooth on your smartphone. Try connecting to another device: a speaker, a car stereo, or a friend's headphones, and that will help localize the problem: if the phone can't see anything, it's the smartphone; if the other devices work and the Redmi Buds don't, the problem is that.
💡
Use a third-party app like Bluetooth Scanner to see if your headphones are streaming. MAC-Addresses on the air, even if the phone does not display them in the standard menu.
It is important to make sure that the distance between the devices is minimal. For initial pairing, put the headphones and phone next to you, removing any metal objects or powerful sources of interference (wi-fi routers, microwaves) from the immediate vicinity.
Reset procedure for Xiaomi headphones (Hard Reset)
If a simple reboot doesn’t work, you need to perform a full Hard Reset, which brings the headphones back to factory status by removing all saved profiles and equalizer settings. The procedure may be slightly different for different Xiaomi models, but the general principle is the same.
For most models, such as the Redmi Buds 3/4 or Mi True Wireless Earbuds Basic, you need to place both headphones in the charging case and leave the lid open. Find the function button on the case case case case (usually hidden or small) and hold it for 10-15 seconds.
The indicator should start flashing white (or orange, depending on the model), which signals a successful reset and transition to pairing mode.In models without a physical button on the case (for example, some versions of Mi True Wireless Earphones 2), the reset is performed by touch control, you need to simultaneously touch the touch areas on both headphones and hold for about 5-7 seconds until the indicators blink.
☑️ Checklist for headphone reset
⚠️ Warning: After resetting, the headphones will forget all previous connections. You will have to re-search them in the Bluetooth list on your phone and reconfigure touch control through the app.
Setup via Mi Home and Xiaomi Earbuds
Xiaomi ecosystem is tied to the use of proprietary software. For full-fledged work and flashing headphones, be sure to use Mi Home applications or specialized Xiaomi Earbuds (for global versions). Sometimes the connection problem is solved by updating the internal firmware of accessories.
Go to the Bluetooth settings on your smartphone, tap the gear next to your headphones (if they show up) and select "Disable" or "Forget Device." Then open the Mi Home app, press "+" to add the device, and follow the instructions on the screen.
If the application detects an available firmware update, be sure to install it. Often, manufacturers release patches that fix problems with connection stability and audio delay. The upgrade process requires a stable Internet connection and a headphone battery charge of at least 50%.
What to do if the app does not see the headphones?
The app also checks the balance of charging between the left and right earphones, and if one of them is more discharged, the system can block the connection, waiting for the leveling of the charge levels.
Fix Bluetooth problems on Android and MIUI
The problem may lie in the cache of Bluetooth services of the Android operating system. Accumulated errors can prevent the module from working correctly. To clean, go to the phone settings, find the Applications section, select Show System Processes, and find Bluetooth.
From the menu of the selected app, click on Storage and select Clear Cache and Clear Data. This action will reset all Bluetooth network settings, but will not affect your personal files or contacts.
| Action. | The path to the menu (example for MIUI 14) | The result |
|---|---|---|
| Reset Bluetooth | Settings → Connection and Sharing → Bluetooth → Cogs → Reset | Removal of all pairs |
| Clearing the cache | Settings → Applications → All applications → Bluetooth → Storage | Deletion of temporary files |
| Resetting the network | Settings → Connection and Sharing → Reset Wi-Fi, Mobile Network and Bluetooth | Complete reset of network settings |
Also worth paying attention to is the power saving mode. If Ultra-energy saving or aggressive battery optimization is activated, the system can force the Bluetooth module to save charge. Add the Mi Home app to the battery optimization exceptions.
💡
Cleaning the Bluetooth cache and resetting network settings eliminates 80% of software conflicts that arise after updating the smartphone operating system.
Specificity of connection to different devices
Sometimes the headphones work perfectly with a Xiaomi smartphone, but refuse to connect to a Windows laptop or an Android TV. This is due to the peculiarities of codecs and audio profiles. Make sure that the receiving device has A2DP profile support.
When connecting to a PC via a USB-Bluetooth adapter, drivers may be required. Built-in laptop adapters sometimes conflict with third-party software. Try to disable other Bluetooth devices (mouse, keyboard) while pairing the headphones to avoid interruption conflict.
For Mi TVs, TV redmi TV It's a very late connection, and after selecting the headphones in the TV list, it can take up to 30 seconds to wait before you get "Connected." Don't try again. PIN-code (usually 0000 or 1234) too fast.
💡
When connecting to Windows 10/11, use only the standard Add Device menu, avoiding third-party utilities from the manufacturer of the Bluetooth adapter, which often work incorrectly.
