Modern wireless headphones from Xiaomi and its sub-brands such as Redmi and QCY have become the standard of quality in the budget and mid-range segment, but owners often face a situation where the device stops working as a single system, and the sound is played only on one side, this is due to the dissynchronization of channels, when the right and left modules “forget” that they should work in pairs.
Reconnecting them requires a sequence of actions, which in the technical documentation is called steaming or resetting to factory settings. It is critical to understand that the process is not always the same for different generations of devices, as firmware and pairing algorithms vary from model to model. In this article, we will discuss in detail the universal methods and specific nuances for different versions of headsets.
Before you start complex manipulations, you need to make sure that the problem is the software sync failure, not a dead battery or mechanical damage. Often users start resetting when it was enough to just clean the charging contacts. We will look at all the stages of diagnosis and recovery, so you can get your Mi True Wireless back to full operation.
Diagnostics of the problem of desynchronization
The first sign that the headphones have lost touch with each other is that the smartphone is independently displayed in the Bluetooth list. Instead of a single device, like the Mi True Wireless Earbuds Basic 2, you see two separate connections, or only one of them plays sound, which means that the TWS (True Wireless Stereo) mode is deactivated, and there is no stereo effect.
Sometimes the problem is silent or no sound in one channel, even if both modules are connected to the phone. In such cases, the mobile device’s operating system may perceive them as two different mono-devices. Android and iOS do not always correctly handle such a failure, requiring manual user intervention to restart the connection protocol.
⚠️ Warning: If one of the headphones emits intermittent squeak or flashes red faster than usual, this may indicate a deep battery discharge, not a software glitch.Be sure to place both modules in the case for at least 30 minutes before resetting.
It's also worth checking if the device is connected to another gadget nearby. Connection priority is often given to the last active device. If your headphones are stuck on a tablet or laptop, the phone can see them, but it can't transmit an audio stream, which creates the illusion of a malfunction.
Preparation for the remating procedure
To successfully perform the reconnection procedure, you need to create clean conditions for connection, which means completely removing old pairing profiles from your smartphone memory. Go to Bluetooth settings, find your Xiaomi Earbuds in the list, and click “Forget device” or “Disable”.
Make sure the modules are sufficiently charged. The remaping process requires active radio modules, and if the battery sits in the middle of the procedure, the headset can enter debugging mode or lock down. The optimal charge level for starting work is at least 50%.
☑️ Ready to dump
It is important to turn off Bluetooth on all devices that have previously been associated with this headset.This will prevent automatic reconnection during the setup process.If you have a Xiaomi smart home or other gadgets of this brand, they may try to intercept the signal, which will knock the synchronization algorithm.
💡
Before starting the procedure, wipe the gold contacts on headphones and inside the case with a dry lilaless napkin. Contact oxidation is a common reason that headphones do not charge in the case and do not reset.
Universal method of resetting through touch panels
The most common way to restore connection is relevant for most models, including Redmi AirDots and Mi True Wireless Earbuds Basic. The essence of the method is to force the headset into pairing mode using touch buttons, which works when the standard connection is broken.
Remove both earbuds from the charge case. Wait until they turn off (usually 5-10 seconds after retracting if no connection is in place). Then press and hold the touchpads on both headphones simultaneously. Retention time is about 20 seconds. The indicators should flash red several times, after which they will flash white quickly.
- 🔴 Red flashing means entering reset mode.
- ⚪ White flashing signals switch to pairing mode (Pairing Mode).
- 🔵 Blue blinking (on some models) indicates a successful connection between each other.
- 🔊 Voice message "Pairing" confirms readiness to connect to the phone.
Once the lights are white, turn on Bluetooth on your smartphone and search for the devices. One device should appear on the list. If you see two, then the synchronization between the left and right channels has not yet passed, and the procedure should be repeated, holding the buttons longer.
⚠️ Warning: When holding the touchpads, don't let them go when you blink first. Many users mistakenly stop acting too early. You have to wait for a series of quick blinks, which takes about a few minutes to make. 20-25 seconds.
Specificity of reset for models with buttons on the case
More advanced models, such as the Mi True Wireless Earphones 2, 2 Basic or 2S, have a physical button on the charging case itself, which makes it much easier to do so, as it doesn’t require precise touch zones on the headphones themselves, which is especially useful when working with gloves or wet hands.
Place both earbuds in the case and leave the lid open. Find a circular button on the case (usually located on the end or between the ear compartments). Press and hold this button for 10-15 seconds. The indicator on the case will flash white, indicating readiness for pairing.
Unlike the previous method, it's important that the headphones are inside the case, and it's the case that acts as the Master that initiates the reconnection of the satellites, and if the case indicator doesn't respond, check if the headphones fit tightly into the contacts.
What to do if the button on the case does not work?
Once you activate the case search mode, open Bluetooth on your phone. The device should be defined as a single device. If the connection is successful, but the sound is only on one side, try playing the audio and pressing the touchpad of the working earphone — sometimes this forcefully transmits a signal to the second channel.
Use of Mi Wear and Xiaomi Earbuds
For owners of the Xiaomi ecosystem, the official Mi Wear app (formerly Mi True Wireless) is an excellent tool for diagnosing and configuring, which allows not only to manage functions, but also to perform a software reset if physical buttons do not respond or work incorrectly.
Download the app from Google Play or the App Store and connect your headphones to your smartphone. In the main menu, select your device. In the settings menu (usually a gear icon or three dots), find "Reset your headphones" or "Factory Reset" and this action will delete all equalizer settings and reconnect the channels.
| Model headphones | Type of management | Reset indicator | Retention time |
|---|---|---|---|
| Redmi AirDots 1/2 | Sensory (on the ears) | Red -> White | 20-25 seconds |
| Mi True 2/2S | The button on the case | White flashing | 10-15 sec. |
| Mi True 2 Pro | Touch + Case | Orange/White | 10 seconds. |
| FlipBuds Pro | Annex/Case | White flashing | 10 seconds. |
The app also allows you to update the firmware of the headphones. Often the problem of desynchronization lies in the bugs of the old version of the software. Updating Firmware through the application can automatically correct communication errors between modules without the need for manual reset.
Frequent Problem Solving and FAQ
Even after all the instructions are followed, there may be nuances that depend on the Bluetooth version of the module in the phone or the operating system, for example, some Samsung or Huawei smartphones require additional permission to access the microphone for the second channel manually in Bluetooth settings.
If nothing works, try the hard method: completely discharge the headphones, leaving them on outside the case, and then put them on charge for several hours. Sometimes a full recharge cycle resets the power controller, which could block one of the channels.
💡
The main reason for failure is rush. Synchronization algorithms take time to exchange handshake packets. Give the device 10-15 seconds after turning on before trying to connect to the phone.
In rare cases, the problem is hardware in nature, and if one of the headphones fell from a height or came into contact with moisture, its radio module could get damaged, and in this situation, software methods will not help, and you will need to replace the faulty module.
