Modern wireless headsets from Xiaomi and sub-brands like Redmi or Poco have become the benchmark for affordable sound, but users often find that one of the headphones stops working in pairs, playing only one side of the sound or not connecting to the smartphone at all, due to desynchronization, when left and right channels “forget” that they have to work together.
Reconnecting modules is not a complex process, but requires precise sequences, and unlike normal Bluetooth speakers, you have to force reset your pairing settings and reconnect the devices to each other, not just your phone.
In this article, we will discuss the universal methods suitable for most models. TWS-You will learn how to perform a complete reset, clear the connection history on your smartphone and properly initialize the reconnection for stable stereo sound performance.
Preparation for the procedure of resetting and cleaning the Bluetooth cache
Before you start manipulating the headphones themselves, it is critical to prepare the smartphone to which you plan to connect them. Often the cause of problems is not a hardware failure of the headset, but a “stuck” profile in the phone’s memory, which contains erroneous data about previous sessions.
Go to your mobile device's Bluetooth settings. Find your model from the list of available devices, such as Mi True Wireless Earphones 2 or Redmi Buds 3. Click on the gear icon or information next to the name and select "Forget Device" or "Delete".
Once the profile is removed, it is recommended to turn off Bluetooth completely on the phone, which breaks all background search processes that may interfere with the initial pairing procedure, and leave the wireless module off until we reset the headphones themselves.
⚠️ Warning: Make sure both headphones are in the case and have a charge of at least 20%.If the battery is discharged to zero, the reset procedure may be interrupted halfway, which will lead to incorrect operation of the controller.
It's also worth checking if your headphones are connected to other gadgets nearby. If a tablet or laptop nearby tries to automatically restore the connection, this can block the synchronization process.
Universal Reset Method through Touch buttons
The most common way to restore the headset is to use touch panels or physical buttons on headphone cases, a method that is suitable for most AirDots, Basic and Youth models. The algorithm here is based on simulating prolonged pressing, which puts the device in flashing mode.
Remove both earbuds from the charge case. If they turn on and start flashing, you need to manually turn them off. To do this, press and hold the touch areas on both devices simultaneously for 5-7 seconds until the indicators go out.
When the headphones are off, start the basic reset process. Press and hold the touchpads on both headphones simultaneously. Hold on for a long time, about 20 seconds. First you see the lights flashing (usually in red), then they can blink white or blue, and only then you start to blink fast, signaling the reset mode.
☑️ Checklist of correct reset
When the lights start flashing frequently (usually 3-4 times per second), release the buttons. Now put both headphones back in the case, close the lid and wait 10 seconds. After that, retrieve them - they should automatically enter pairing mode with each other.
Now you can turn on Bluetooth on your smartphone and start searching. You should have one device on the list. If you see two identical names, like two "Mi True Wireless EBs Basic," then the sync between them has not happened, and you need to repeat the procedure.
Specificity of reset for models with a mechanical button on the case
More advanced models, such as the Mi True Wireless Earphones 2 Pro, FlipBuds or Redmi Buds 3 Pro, often feature a physical button on the charging case itself, which simplifies the process, as it does not require jewelry accuracy when pressing the sensors on the ears themselves.
Place both earbuds inside the case. Leave the lid open. Find a round button on the case (usually on the end or inside between the ear compartments) and press it and hold it for 10 seconds.
The indicator on the case will start flashing white, which signals the transition to pairing mode, at which point the internal memory of the headset is cleared, release the button when the blink becomes intermittent or changes color.
| Model headphones | Type of management | Retention time | Indication of discharge |
|---|---|---|---|
| Redmi AirDots | Sensory | 20 seconds. | Triple flashing. |
| Mi True Wireless 2 | The button on the case | 10 seconds. | White flashing |
| Xiaomi Buds 3T | Touch (in case) | 10 seconds. | Orange light |
| FlipBuds Pro | The button on the case | 10 seconds. | Pulse. |
Always check the instructions for your specific modification.
What to do if the button on the case does not respond?
Use the Mi Earbuds app to customize
For Android smartphone owners, the official Mi Earbuds app (formerly known as Xiaomi Earbuds) is an excellent diagnostic and setup tool, which allows not only to track the charge, but also to force the reconnection of components.
Download the app from Google Play or Mi GetApps. Run a device scan. If the app sees your headphones but it's "Connection Error" or "One Ear Only," try using the firmware update feature inside the app.
Often, firmware updates automatically fix sync errors between channels, a process that takes a few minutes, but you can't open the case or pull the phone away.
⚠️ Warning: Do not interrupt the firmware update process. If the battery sits down while writing new data to the controller's memory, the headphones may turn into a brick and stop responding to any commands.
The app also features a "Reset Settings" feature that software-cleanses the connection profile, an alternative to mechanical button clamping and often works more reliably for complex models with active noise cancellation.
💡
Use the Mi Earbuds app to calibrate your sensors. Sometimes the problem isn't Bluetooth, but that the ear-removal sensors aren't working properly, and the earphone thinks it's in the ear, even though it's in the case.
Diagnostics of charging and contact problems
A common cause of desynchronization is the banal lack of charge on one of the headphones. The user puts the devices in the case, but due to contamination of contacts or misalignment of magnets, one of the headphones does not charge, so when you open the case, one earphone is turned on and the second remains dead weight.
Carefully inspect the contact areas on the headphones themselves and inside the case, often accumulating earwax, dust or oxides, and wipe the contacts with a dry lilaless napkin or cotton swab lightly soaked in alcohol.
Check if the headphone lights up when you put it in the case. If the light doesn't light up, try moving the headphone inside the socket. If you get a contact, it means it's a bad fit.
It's also worth checking the charging cable and the power supply. Using too powerful fast-charging adapters from smartphones can sometimes cause charge controller conflicts in cheap headphone models. USB-port of the computer or block of 1A.
Synchronization Features for Game Modes and Codecs
Some Xiaomi models support low latency game modes, which increases the need for stable left-right connection when activated, and if synchronization is disrupted, the games may lose sound or echo.
To activate the game mode, you usually need to triple tap the sensor. Make sure this feature does not conflict with the basic Bluetooth settings. In rare cases, switching the audio codec in the Android developer settings (for example, from AAC to SBC) helps.
If you use headphones from a PC, make sure that the Bluetooth adapter drivers are updated. Windows sometimes mishandles the stereo mode of Xiaomi headsets, dividing them into two audio output devices: "Stereo" and "Hands-Free AG Audio".
💡
Key point: For stable gaming and video experience, always choose a Stereo profile in Windows audio settings, rather than Hands-Free, which is monophonic and low quality.
Solving problems if headphones can't see each other
There are times when all methods have been tried, but the headphones still work independently, which may indicate that one of the modules is stuck in standby mode. Try discharging both earphones completely, leaving them on outside the case, and then charging to 100% when off.
Another method is hard rebooting through discharge. Leave the headphones out of the case for 24 hours. Then insert into the case for 2 hours. Then perform the reset procedure (20 seconds of retention) again. Often, cyclical rebooting helps to reset software errors.
If nothing helps, the problem may be the hardware, the Bluetooth module in one of the headphones has failed, in which case only maintenance or replacement of the faulty component will help.
⚠️ Warning: If after all the reset attempts, one earphone flashes red and blue and the other is silent, this is a sign that they can't find each other. Try to move away from interference sources (Wi-Fi routers, microwaves) and repeat the procedure.
