The situation where your favorite wireless headphones suddenly stop connecting to your smartphone is familiar to many users of the Xiaomi ecosystem. Whether it is the popular Redmi Buds models, Mi True Wireless Earbuds or the more advanced FlipBuds, Bluetooth connection problems can occur at the most inopportune moment, most often after upgrading the phone's operating system, discharging batteries to a critical level, or a software failure in the communication module.
Restoring a stable headset usually does not require contacting a service center and can be done on your own in a few minutes. The key to solving a problem is the correct sequence of actions, since chaotic pressing of the buttons can only aggravate the situation, driving the device into uncertainty mode. In this article, we will discuss all the stages of diagnosis and repair of the software part of the headphones.
Before you get into the tricky stuff, you have to understand that Bluetooth wireless is extremely sensitive to interference and software status. If you notice that the sound is interrupted, the channels are out of sync (only one earpiece plays), or the phone doesn't see the device at all, don't panic, and most of these are solved by the standard reset and reconnect algorithm, which we'll describe in detail below.
Primary diagnostics and basic checks
The first step in fixing any electronics problems is to rule out the obvious reasons. Often the problem is not with the device itself, but with the elementary battery discharge or on flight mode. Make sure your smartphone has a Bluetooth module activated and is visible to other devices. Also check if the headphones are connected to another gadget nearby, as many Xiaomi models try to automatically reconnect with the last active device.
It is important to inspect the charging case and the headphones themselves for contact oxidation. Dirt or dust on the contact areas inside the case can prevent charging, which prevents the headphones from turning on and therefore do not enter the pairing mode. Wipe the contacts with a dry waxless napkin. If the headphones do not light up when removed from the case, try to leave them charging for 15-20 minutes.
⚠️ Warning: If the lights flash red constantly even while charging, it may indicate a deep battery drain or charging case malfunction.
Check the list of paired devices in your phone settings. If there are old notes on your headphones marked "not connected" or duplicates, they must be deleted. Sometimes the Android or iOS operating system stores cached connection profile data that conflicts with the current state of the headset. Deleting the old profile is a must before trying a new pairing.
Complete reset of headphones (Hard Reset)
If the basic checks didn't work, you need to reset your headphones to factory ones, which clears the internal memory of the Bluetooth module and removes all previous pairing settings. The process may vary slightly between Xiaomi and Redmi models, but the general principle remains the same. You need to put both headphones in the charging case and leave the lid open.
Most models, such as the Mi True Wireless Earphones 2 or Redmi Buds 3 Pro, have a button on the back or inside of the case. To perform the reset, press this button and hold it for 10-15 seconds. The status indicator will flash white or orange (depending on the model), which signals the start of the reset process.
☑️ Checklist for headphone reset
For models without a physical button on the case (such as some versions of Airdots), the reset is performed through the touch panels of the headphones themselves. Usually you need to remove them from the case and simultaneously touch the touch zones on both headphones, holding your fingers for about 5-7 seconds until the sound signal or color changes of the indicators.
| Model headphones | Resetting method | Indication of success | Retention time |
|---|---|---|---|
| Redmi Buds 3 Pro | The button on the case | Orange blinking | 10 seconds. |
| Mi True Wireless 2 | The button on the case | White flashing | 15 seconds. |
| Redmi AirDots | Headphone sensors | Red flashing | 5-7 seconds |
| Mi FlipBuds Pro | The button on the case | Sound signal | 10 seconds. |
Elimination of channel dissynchronization
One of the most annoying problems is when the headphones work independently: the left has music and the right has silence, or they connect to the phone as two different devices, which is called TWS (True Wireless Stereo) desynchronization. To fix this, you have to pair the left and right headphones together again, eliminating the phone from the equation.
Start by completely removing (forget) the Bluetooth headphones on your smartphone and turning off the Bluetooth itself on your phone. Put both headphones in the case, close the lid and wait 10 seconds. Then pull out both headphones at the same time. They should start blinking quickly, entering search mode for each other. If one of them keeps blinking slowly or doesn't blink at all, put it back in the case, and then pull it out again.
What to do if one earpiece is not paired?
When the indicators on both headphones start flashing synchronously (usually slowly), this means that the lights on both earphones will start to flash in sync. TWS-And then you can turn on the Bluetooth on your smartphone and search for the device, and it's important not to try to plug each earphone separately, but the phone needs to see them as one device. If the phone sees two devices with the same name, then the synchronization failed, and the reset procedure must be repeated.
Working with the Xiaomi Earbuds app
For deep tuning and diagnostics, it is recommended to use the official Xiaomi Earbuds app (or Mi Buds for older models), which allows you not only to control noise reduction and equalizer, but also to check the version of the headphone firmware. Often connection problems are caused by bugs in the old version of the firmware, which are fixed by developers in updates.
Connect your headphones to your phone and launch the app. If the connection is unstable, the app may suggest updating your firmware. During this process, keep the case with your headphones next to your phone and don't open the lid. Interrupting the update can cause the headphones to stop turning on at all. If the app doesn't see the headphones, try clearing the app's cache in your Android settings.
The app also has a headphone search and sensor calibration feature. If you have trouble recognizing touches or removing the earpiece (automatic pause), calibrating through the app can help restore the correct operation of the proximity sensors, which indirectly affects the stability of the connection, as it reduces the load on the headset processor.
Problems of compatibility and settings of the smartphone
Sometimes the reason lies not in the headphones, and in the settings of power saving smartphone Xiaomi (MIUI or HyperOS).
