Xiaomi’s wireless headphones are starting to work independently, a familiar experience for many ecosystem users. Instead of the usual stereo sound and automatic synchronization, the smartphone sees two different devices, such as the “Mi True Wireless EBs Basic” and “Mi True Wireless EBs”. Basic_R". That means that TWS-The mode (True Wireless Stereo) was broken, and the gadgets lost communication with each other.
The most common problem is software failure or unsynchronization of connection profiles. The right earpiece is usually a master device that transmits a signal to the left, and if this chain breaks, the user is faced with monophonic sound or complete absence of sound in one of the channels. You can restore normal operation yourself without contacting the service center.
In this article, we’ll look at all the effective ways to solve the problem, from simply resetting your settings to deep cleaning your Bluetooth profiles in the Android operating system. It’s critical to follow all the steps consistently, as skipping the cleaning phase of your phone’s memory can cause the error to repeat.
Reasons for desynchronization TWS-headset
Before you start taking action, it’s worth understanding the nature of the bug. The Bluetooth protocol in Xiaomi’s budget and mid-range models is designed so that one headphone (master) connects to the phone, and the second (slave) connects to the wizard. If communication between them is interrupted, they start looking for the device again and can connect to the phone as two independent sound sources.
One common cause is that batteries run out at different times, and if you only used one earbud while the other was in the case, their charge levels and connection statuses could be out of sync, and interference on the air or being in range of other active Bluetooth devices can knock off pairing settings.
⚠️ Warning: Frequently changing connection devices (e.g. switching between laptop, tablet, and phone) without first breaking communication increases the risk of out-of-synchronization.
In addition, software errors of the smartphone operating system itself sometimes incorrectly preserve device profiles. Android can "remember" headphones as two different gadgets after updating the system or resetting network settings. In rare cases, the fault is the contamination of charging contacts in the case, which causes one of the headphones does not charge fully and goes into sleep mode, breaking the connection.
Preparations for re-establishment of communications
To successfully perform the reconnection procedure, a number of preparatory steps must be performed, which will eliminate the influence of external factors and ensure the purity of the experiment, first of all, make sure that both earphones are sufficiently charged, otherwise one of them may turn off during the setup process.
Put both earbuds in the charger case and close the lid. Wait about 5-10 seconds, then open it. The indicators should light up, signaling the start of charging and activation. If the indicator on one of the headphones is not burning, wipe the contacts with a wet wipe and dry cloth, then repeat the procedure.
☑️ Checking the readiness of headphones
Then you go to the Bluetooth settings on your smartphone. Find your headphones in the list of paired devices. If it shows two identical names or the same name with a " R" or " L" name, click on the gear or information icon next to each of them and choose Forget the device or Break the connection. This is a critical step that is often ignored.
The method of complete soldering (Hard Reset)
The most effective way to get the headphones to see each other again is to perform a full reset (Hard Reset), which clears the internal memory of the Bluetooth modules and returns them to the factory settings. For different Xiaomi models, the algorithm may differ slightly, but the basic principle is the same.
Remove both earbuds from the case. Make sure they're not connected to the phone (Bluetooth on your smartphone is better off temporarily). Press and hold the touchpads on both headphones simultaneously. Retention time varies from 5 to 20 seconds depending on the model.
- 🔴 For Mi True Wireless Earbuds Basic: Hold on 15-20 seconds before flashing the indicator 3 once.
- 🔵 For Redmi AirDots: Hold 5 seconds before turning off, then another 15 seconds before turning on and blinking.
- 🟢 For Mi True Wireless EBs Basic 2: hold 5 seconds to shut down, then quickly press 2 times and hold 3rd time (5 seconds).
- 🟡 For Xiaomi Buds 3/3 Pro: Place in the case, open the lid and hold the functional button on the case 10 seconds.
After the lights have flashed a certain number of times (usually red or white), put the headphones back in the case. Close the lid for 10 seconds. Now open the case - the headphones should automatically try to connect with each other. If everything goes well, only one indicator will flash (or they will blink less often), which means creating a pair.
What if the reset didn’t work the first time?
Cleaning Bluetooth profiles on a smartphone
Even after a successful headphone reset, the phone can continue to "remember" old, incorrect settings. To avoid conflicts, you need to completely clear your connection history. Turn on Bluetooth on your smartphone and start looking for new devices.
In the list of available devices, you should only see one name of your headphones, and if you see two identical names, it means that the synchronization between the headphones themselves has not yet occurred, in which case, do not try to connect, but go back to the reset step.
When you have one device left on the list, click on it to pair, if the system asks for confirmation or code, you'll agree. Once you've connected, check the sound. If there's sound in both channels, the problem is solved.
| Model headphones | Indication of discharge | Retention time | Post-discharge action |
|---|---|---|---|
| Mi True Wireless Basic | 3 red flashes | 15-20 seconds | Put it in the case. |
| Redmi AirDots S | Blink 2 times | 5 sec (off) + 15 sec | Close the case. |
| Mi True Wireless 2 | White flashing | 10 seconds (case button) | Open the case. |
| Redmi Buds 3 Lite | Orange blinking | 5 sec (sensors) | Reconnect. |
It is important to note that some models, such as the Xiaomi FlipBuds Pro, require the use of the branded Xiaomi Earbuds app for full functionality, but the basic reset works without it.If after connecting through the standard Bluetooth menu, the sound is unstable, try uninstalling the device again and plugging in through the app.
Use of the Xiaomi Earbuds app
For owners of modern models Xiaomi and Redmi, the official Xiaomi Earbuds app (formerly Mi True Wireless) will be an excellent assistant, available on Google Play and the App Store, which allows you not only to track the charge, but also to reset the settings by software, which is sometimes more effective than mechanical.
Launch the app and press "Add Device." Follow the instructions on the screen. If the headphones are unsynchronized, the app may suggest a firmware update. The software update often fixes Bluetooth protocol bugs that cause channel disconnection.
Inside the app, you can also check the volume balance of the left and right channel. Sometimes users feel like the headphones are working separately, when in fact the balance is knocked off or mono-audio mode is turned on in the phone settings. Check the "Sound settings" section of the app and make sure that the sliders are in the center.
⚠️ Warning: During the firmware update through the application, do not open the case cover and keep the phone next to the headphones. Interrupting the process can lead to complete inoperability of the device.
Problems with charging and contact
And you can't discount the physical reasons, either. If one of the headphones doesn't charge in the case, it won't turn on and it won't sync with the pair. Visually, it can look like a job on its own: you take out both, one is running (because it was charged), and the other is silent or looking for the device.
Check the contacts on the legs of the headphones and inside the case, they often accumulate earwax or oxidize metal. Use a cotton swab, slightly soaked in alcohol, for a careful cleaning. After cleaning, let the contacts dry for 2-3 minutes.
Also check if the case cover fits tightly. If the latch mechanism is loose, the headphones may not be in contact with the charging magnets, in which case either replacing the case or using third-party chargers with contacts (if the model supports).
💡
Use a toothpick with a microfiber wrapped on the tip to clean hard-to-reach speaker grids and contacts so as not to damage small details.
Specific settings for Android and iOS
Sometimes the problem is not the headphones, but the operating system settings. There's a Monoaudio option on Android that brings the stereo to one channel. If it's on, the second headphone may be silent or not working correctly. Go to Settings → Special features → Improve hearing and make sure the Monoaudio switch is off.
For iOS users, balance check is relevant. Path: Settings → Universal Access → Audiovisualization → Balance. The slider should be strictly in the center. iOS also has an Auto Switch feature that can conflict with Xiaomi’s budget models, trying to transfer the sound to another Apple device.
Another possible reason is the overcrowded cache of the system's Bluetooth services. On Android, you can try resetting the network settings (this will remove all stored Wi-Fi and Bluetooth pairs). Way: Settings → System → Settings Reset → Reset Wi-Fi, mobile network and Bluetooth.
💡
Resetting network settings on the phone is a radical, but often the only working method when software failures of the OS block correct pairing. TWS-device.
