The problem of wireless headphones being out of sync is one of the most common among users of the Xiaomi ecosystem. Often owners are faced with a situation where one headphone is working and the second is silent, or both devices play sound independently from each other, making listening to music impossible. In such cases, you need to perform a procedure of forced pairing of the left and right channel to work again as a single stereo system. The process of restoring communication between the modules does not require deep technical knowledge, but requires accurate adherence to the sequence of actions.
There are several reasons why TWS-These headphones can lose communication with each other, which can be a software failure in the firmware, the discharge of one of the batteries to a critical level, or a conflict with previously connected Bluetooth devices. It is important to understand that before you try to reconnect them, you need to completely clear the connection history on your smartphone. Ignoring this step often leads to the fact that the synchronization procedure is unsuccessful, and the gadgets continue to behave chaoticly.
In this guide, we will go through all the steps to restore your Mi True Wireless Earbuds. We will look at the standard reconnection procedure, hard reset methods for different models and how to solve specific problems specific to Xiaomi devices. Following the instructions, you can return your headphones to full operation without going to the service center.
Preparation of devices for communication restoration
The first and most important step is to properly prepare the equipment. Before you start any manipulations, make sure that both the headphone and the charging case are sufficiently charged. If one of the modules is completely discharged, it will not be able to enter the pairing mode. Put both devices in the case and leave them on charge for at least 15-20 minutes, even if the indicators indicate the presence of power.
The next critical step is to remove the device from the smartphone memory. Without this step, all further action may be in vain, as the phone will try to connect to old configurations. Go to your Android or iOS device's Bluetooth settings, find your Mi True Wireless Earbuds in the list, and select the option "Forget the device" or "Unpair."
⚠️ Warning: Make sure that Bluetooth on your smartphone is completely off before starting the earphone reset procedure.If the phone is actively scanning the air, it may intercept the signal of one of the headphones as they try to sync with each other, which will lead to a repeat of the error.
After you turn off Bluetooth, you need to clear the Bluetooth cache on your phone if previous attempts to connect failed. This can be done through the application menu in the system settings. Find the Bluetooth app, go to the storage and click Clear the cache. This action will delete temporary files that may have caused the address conflict.
- 🔋 Charge the case and headphones to at least 50% for stable operation.
- 📱 Remove the headphone profile from the list of saved Bluetooth devices on your phone.
- ❌ Turn off the wireless module on your smartphone or tablet completely.
- 🧹 Clean the metal contacts on the headphones and inside the case with dry cloth.
Only after all the preparations are complete can you go directly to the connection procedure. Take your time, because the correct preparation guarantees success in 95% of cases. If you miss cleaning the contacts, the headphones may simply not charge in the case, which will lead to their turning off at the most inopportune moment.
Standard Reset (Soft Reset) Procedure
The easiest way to get the left and right headphones to see each other again is to perform a soft reset, a procedure that is suitable for most Mi True Wireless Earbuds Basic, Essential and AirDots models.
Remove both earbuds from the charge case. At that point, they should light up with indicators. If the indicators are not on, make sure the devices are properly positioned on the contacts. Now you need to simultaneously touch the touch areas (or physical buttons, depending on the model) on both earbuds. Hold your finger until the indicators start flashing red and white (or blue) colors.
When the lights flash, release the buttons. The headphones should start looking for each other. Usually the left channel (L) acts as a master, and the right channel (R) connects to it. In the process of searching, the indicators can flash at different speeds. In 5-10 seconds, one of the indicators should go out or start blinking slowly, which will mean successful connection of channels between each other.
☑️ Checking successful pairing
Once the indicators have shown successful synchronization, turn on Bluetooth on your phone and start looking for new devices. The list should only show one device with the name of your model, not two identical ones. If you see two devices with the same name, then the procedure failed, and the headphones did not connect.
- 👆 Simultaneously press the touch panels on both headphones.
- ⏳ Keep until the red and white flashing of indicators appears.
- 🔗 Wait until one indicator goes out and the second lights up slowly.
- 📲 Turn on Bluetooth on your phone and search.
It is important to note that in some models, such as the Mi True Wireless Earphones 2, the procedure may differ by having a physical button on the case, in which case, place the headphones in the case, open the cover and press the button on the case, holding it for a few seconds before the indicator on the front panel blinks.
Full reset to factory settings (Hard Reset)
If standard reconnecting doesn't work, you need to perform a hard reset, which brings the headphone firmware back to factory status by removing all internal settings and addressing conflicts, and it's the most effective way to solve desynchronization problems.
Place both earbuds in the charge case and make sure they charge (indicators are on). Without closing the case cover, find the function button. Depending on the model, it can be on the back wall of the case or inside between the headphone compartments. Press and hold this button for 10-15 seconds.
The following steps for Hard Reset:
1. Put the headphones in the case.
2.Push the button on the case and hold 15 seconds.
3. wait for the indicator to flash triple.
4. Remove the headphones and check the synchronization.The indicator on the case should flash three times white (or red, depending on the version), which signals a successful reset. After that, remove the headphones. They will automatically go into pairing mode. Now they can be reconnected to the phone as a new device.
What to do if there is no button on the case?
⚠️ Warning: During the reset, do not remove the headphones from the case prematurely. interruption of the process until the triple blinking is completed may damage the Bluetooth module software.
For models without a button on the case, such as some versions of the Mi AirDots, the "five-up" method is used. Remove the headphones, turn them off (holding 5 seconds), then turn on and immediately tap the touchpad 5 times quickly on each headphone.Indicators should blink, confirming entry into flashing or reset mode.
Synchronization Features for Different Xiaomi Models
Xiaomi’s ecosystem includes many headphone models, and the procedures for setting them can have their own nuances. Understanding the differences between the Mi True Wireless Earbuds, Redmi Buds and Mi AirDots series will help avoid errors.
The Mi True Wireless Earbuds Basic and Essential series models often require manual intervention through touchpads. whereas more advanced versions, such as the Mi True Wireless Earphones 2S or Pro, often support rapid pop-up pairing on Xiaomi and Redmi smartphones. However, when channel communication is lost, the algorithm for all of them is reduced to reset.
| Model headphones | Type of management | Indication of discharge | Features |
|---|---|---|---|
| Mi True Wireless Earbuds Basic | Touch-sensitive | red-and-white flashing | Requires accurate timing of the press |
| Mi True Wireless Earphones 2 | The button on the case | Triple white flashing | Resetting through the case is more convenient |
| Redmi Buds 3 Pro | Sensor + Annex | Case indicator | Resetting through Mi Home is recommended |
| Mi AirDots 3 | Touch-sensitive | Fast blinking. | Sensitive to Wi-Fi interference |
Owners of models that support Mi Home or Xiaomi Earbuds are advised to use them to check the firmware version. Sometimes the problem of desynchronization is solved by simply updating the software through official software, without the need for a manual reset.
💡
Use the official Xiaomi Earbuds app to automatically search for firmware updates. Often, channel sync bugs are fixed by the manufacturer in new versions of the software.
And you also have to consider that some models have different left-hand and right-handed logics, and in some cases, the left-hand earpiece is always the master, in others, the one that was first removed from the case, and experiment with the extraction order if the standard method doesn't work.
Solving problems with sound desynchronization
Even after a successful connection, you may experience a situation where sound comes from only one earphone or channels are desynchronized (echo), often due to the sound balance settings in the phone's operating system or the features of the codecs.
Check your smartphone's Accessibility settings. In the "Special Features" section -> "Hearing" (or similar), make sure that the left-right-channel balance sliders are centered. Shifting the balance towards one channel is a common reason users think the second headphone isn't working.
Another reason could be to activate the Mono-audio function. If this option is enabled, the stereo signal is summed up and fed to both channels equally, but sometimes Bluetooth drivers may interpret this incorrectly by disabling one of the channels.
- 🎚️ Check the channel balance in the settings of special features of the phone.
- 🔇 Turn off the Mono-Audio mode in the system sound settings.
- 📡 Switch the Bluetooth codec (for example, with the AAC on SBC) developer-menu.
- 🔄 Reboot your smartphone to reset audio drivers.
If the problem persists, try turning off the Absolute Volume Level feature in the Android developer menu. Sometimes, incorrect synchronization of volume levels between the phone and the headphones causes one channel to be blocked by the system.
⚠️ Attention: Changing the settings in the developer menu requires caution. Write down the initial values of the parameters before changing them so that you can return everything as it was if necessary.
Prevention and care TWS-headphone
To keep the problem of desynchronization from returning, it is important to use the device correctly. The main enemy of the electronics of headphones is moisture and dirt on the contacts. Regularly wipe the contacts with an alcohol napkin to ensure a reliable charge.
Don't let the batteries run too deep. If you don't plan on using the headphones for a long time, charge them to 60-70% and remove them from the case, leaving the case also charged. Storing in a fully discharged state is detrimental to lithium batteries, which ultimately leads to unstable operation of the Bluetooth module.
Try not to drop the case and headphones. Microcracks in the board can manifest itself in the form of periodic loss of communication between channels. Careful handling prolongs the life of the gadget and preserves the sound quality.
💡
Regular cleaning of contacts and avoiding full discharge are the main factors of stable operation. TWS-Xiaomi headphones in the long run.
