Why Xiaomi Headphones Are Not Connected and How to Fix It

When your favorite wireless headphones stop syncing with your smartphone, it often takes you by surprise. Instead of the usual music or voice, you see only a flashing indicator or a pairing error message on the Xiaomi or Redmi screen, a common problem faced by owners of both low-end models like AirDots and flagship FlipBuds Pro.

The reasons can be very different, from the banal discharge of the battery to software failures in the Android operating system. Often it is a crowded memory of the Bluetooth module or a conflict of connection profiles. It is important not to panic and consistently check the basic settings to rule out simple errors before trying a complex repair.

In this guide, we’ll take a look at all the possible scenarios why a device can’t see the headset, and offer step-by-step recovery instructions, learn how to properly perform a full Hard Reset, clear the Bluetooth cache, and configure the developer’s settings for a stable connection.

Primary diagnostics and basic checks

Before you go into complex manipulations, you need to make sure that the problem is not caused by elementary factors, and often users forget that it takes time for the headphones to activate the power controller for the first synchronization or after full discharge. Make sure the battery is at least charged. 20-30%.

Check the physical condition of the contacts. If you use a charging case, make sure that the metal spots on the headphones and inside the case are clean. Oxidation or dust can prevent charging, which will prevent the device from turning on and entering pairing mode.

• 🔋 Make sure the indicators on the case and headphones are on fire when retrieved.
• 📱 Check if the Bluetooth module is on your smartphone and if it is visible to other devices.
• 🧹 Wipe the charging contacts with a dry soft cloth or cotton swab.

Also worth paying attention to the distance between devices. To successfully pair Xiaomi and the headset must be in close proximity - no more than 1-2 meters. The presence of powerful sources of interference, such as microwave ovens or routers operating at 2.4 GHz, can temporarily block the signal.

⚠️ Attention: If the headphones don't light up even after a long charge, the battery or power controller may have failed.

Complete reset of headphones (Hard Reset)

The most effective way to solve connectivity problems is to perform Hard Reset, a procedure that cleans the headset’s internal memory by removing old pairing profiles and resetting settings to factory settings, especially if the headphones have previously connected to other phones or tablets.

For most Xiaomi TWS (True Wireless Stereo) models, such as the Mi True Wireless Earbuds Basic or Redmi Buds, the process looks specific.You need to place both headphones in a charging case, leave the lid open and pinch the touch zones or physical buttons on the case.

Some models, such as the Mi Wireless Earphones 2, require you to press a button on the back of the case, the indicator should start flashing white, signaling the transition to mode (adjugate), after which the old profile in the phone will become inactive, and it must be deleted.

It is important to perform the reset correctly so as not to interfere with the calibration of microphones or noise cancellation. If after reset the sound became quiet or disappeared in one channel, repeat the procedure, strictly observing the time intervals of button retention.

Bluetooth setup and cache clearing in MIUI

The MIUI or HyperOS operating shell has its own wireless connection management features, and sometimes the Bluetooth system service accumulates errors that prevent new devices from connecting, in which case the cache and data of the system application should be cleared.

To do this, go to the phone's settings menu. You need to find the Apps section, then select All Apps and activate the system process display in the menu (three dots in the corner). MIDI Service».

Inside the app menu, click the Clean button and select Clear All or Clear Cache.This action won't delete your personal files, but will reset the list of previously paired devices in the phone's system memory, which often solves the search freeze problem.

After cleaning the cache, it is recommended to restart the smartphone, this will start the system services again with clean parameters. If the problem was a software conflict of Android services, the connection should be successful.

Use of the Xiaomi Earbuds app

For deep diagnosis and management of headset functions, Xiaomi has developed a special application Xiaomi Earbuds (formerly known as Mi Buds) that allows you not only to configure the equalizer, but also to check the status of the connection, update the firmware of the headphones and perform reset software.

If the standard Bluetooth menu doesn't see a device, try running a search inside that app. Sometimes it can detect the headset even when the system claims that the device hasn't been found. The app will also show the exact charge level of each headphone separately, which helps to identify the imbalance.

Updating the firmware through the app is another important step. Manufacturers often release patches that fix connection stability errors. If the software version is outdated, the headphones may not work properly with new versions of Android.

• 📲 Download the app from Google Play or GetApps.
• 🔄 Check for updates in the “Settings” section inside the app.
• ⚙️ Set connection priority for game mode if there is a delay in sound.

Developer and codec mode audio

For advanced users who have experienced connection problems due to codec incompatibility, there is a “Developers” menu, where you can force the settings of audio transmission, which sometimes helps to “friend” the phone and headset.

To activate this menu, you need to quickly click on the build number 7 times in the About Phone section. Then, in the advanced settings, look for the Developer section. We're interested in the Bluetooth settings unit.

Settings → Additional settings → For developers

In this section, you can try changing the Bluetooth version of AVRCP or turning off the absolute volume level, and you can also experiment with the choice of codec: switch from AAC or LDAC to the basic SBC. If the connection stabilizes after that, then the problem was incompatibility of high-resolution codecs.

⚠️ Attention: Changing the settings in developer mode may affect the sound quality or performance of other Bluetooth devices.

Pay special attention to the option “Disable absolute volume level.” Turning on or off this option often solves the problem when the headphones are connected, but the sound is not going or only works on one side.

Hardware malfunctions and compatibility

If the software methods have failed, you should consider a hardware breakdown: the internal Bluetooth module in the headphones is a delicate component, sensitive to shocks, moisture or temperature changes, and there may be problems with the antenna inside the case.

Check the compatibility of Bluetooth versions. Although the standard provides backward compatibility, older headphones (versions 4.0-4.2) can work unstable with smartphones with Bluetooth 5.2 or 5.3 modules, especially in noisy air conditions.

💡

Try connecting your headphones to another smartphone or laptop, and if they work perfectly there, the problem is exactly with your main phone settings, not the headset.

In rare cases, the cause is a magnetic field or static electricity. Try to discharge a static charge by touching a grounded metal object before connecting, and it is also worth checking whether the phone is wearing a too thick case that shields the antenna signal.

If none of the methods worked, and the headphones are not visible on any device within a radius of 10 meters, most likely, a replacement of the Bluetooth module or battery is required.

💡

If the headphones do not connect to any device after resetting and charging, this is a sign of a hardware malfunction requiring repair.
