The situation when only one headphone Xiaomi Mi remains active after extraction from the case is quite common and can spoil the impression of listening to music. Users face this on models of Redmi AirDots, Mi True Wireless Earbuds and others. TWS-In headsets, when devices lose communication with each other or cannot properly mate with a smartphone, instead of stereo, you hear a mono track or silence in one of your ears, which requires immediate intervention.
The problem is often not hardware failure, but the desynchronization of the software inside the headphones themselves. Bluetooth protocol sometimes fails, causing gadgets to “forget” each other and connect to the phone as two independent devices. In this article, we will discuss in detail the algorithms of actions that will help restore the full work of the pair.
Before you jump to the drastic measures, it's worth checking the basic settings of your smartphone. make sure there are no old entries left on the list of available devices about your Xiaomi Mi True Wireless Earbuds that may conflict with the current connection.A clean start often solves half of the communication problems without the need for complex manipulation.
Reasons for desynchronization of headphones Xiaomi
Understanding the nature of the problem helps to avoid recurrence in the future. The main reason one of the channels stops working is because the synchronization protocol between the left and right modules is broken. TWS-systems one headphone (master) transmits a signal to the second (sleeve), and if this chain breaks, the sound disappears.
Another factor may be different battery levels: if one earphone is completely discharged and gone into deep sleep, and the second one remains active, when put into the case, they may not have time to synchronize before the next turn on.
⚠️ Note: If one of the headphones is constantly discharged faster than the other, the problem may not be in the software failure, but in the degradation of the battery or sticking contact pins in the charging case.
Also affected by external interference and features of the smartphone operating system: Some versions of Android or MIUI may not properly handle the A2DP profile when switching between applications, which leads to "hang" audio stream on one channel.
Basic reconnection preparation
Before starting the recovery procedure, you need to perform a number of preparatory steps that are often ignored by users.The first step is to completely clean the list of paired devices in your phone's Bluetooth settings.Look for your Xiaomi Mi True Wireless Earbuds or Redmi AirDots in the list and click on "Forget the device" or "Unpair the pairing."
Next, turn off Bluetooth on your smartphone completely. This action will break all background processes that may try to automatically reconnect gadgets in the background, interfering with the reset procedure. Make sure that both headphones are inside the charging case and the cover is open.
Check the charge of the case itself. The indicators on the case should burn or flash to confirm the presence of energy. If the case is discharged, the headphones will not be able to pass the reset and reset cycle, since the extraction from the case is a signal for them to turn on, not restart.
☑️ Preparation for resetting settings
Mechanical Reset (Hard Reset)
The most effective way to get both headphones to “see” each other again is to perform a full factory reset. For most Xiaomi models, including the Redmi AirDots 2 and Mi True Wireless Earphones Basic 2, the algorithm of actions is unified, but requires accuracy in timing.
Take both earbuds out of the case. If they have physical buttons on them, press and hold them simultaneously for a period of time. 20-30 The indicators should start flashing red several times, after which the headphones will turn off. If there are no buttons (touch control), press the touch areas on both earphones simultaneously.
Sequence of action:
1. Remove both earbuds.
2. Press the buttons/sensors for 20-30 seconds until red flashing.
3. Wait for the indicators to be turned off.
4. Put it in the case for 10 seconds.Once the lights are gone, put the devices back in the charging case. Wait about 10-15 seconds for them to record the charging state, and then retrieve them. At which point they should automatically try to find each other. Usually the right earbud flashes white (pairing mode), and the left one starts to burn or blink less often, which means successful creation of a stereo pair.
What if the reset didn’t help the first time?
Features of connecting different models Xiaomi
Xiaomi's audio lineup is extensive, and control methods can vary depending on the model. For example, the Redmi AirDots series often uses a circuit where the right earbud is the master. If you plug in only the left, there will be no sound until it receives a signal from the right.
More advanced models, such as the Mi True Wireless Earphones 2 Pro, use a chip that supports low latency and improved synchronization. It is important not only to reset the settings, but also to make sure that the firmware is up to date. These devices often require a Xiaomi Earbuds or Mi Wear app through which you can check the status of each headphone separately.
Below is a table that helps identify the behavior of indicators for different series of devices, which is critical for diagnosis:
| Model | Indication of discharge | Interconnection mode | Feature |
|---|---|---|---|
| Redmi AirDots | Red flashing 2 times | White flashing fast | Case charge discharge > 30% |
| Mi True Wireless 2 | Orange blinking | White flashing | An application is required to set up |
| AirDots Essential | Red + White | White flashing | No support for the app |
| Mi Noise Cancelling | Case indicator | Depends on the model. | Reset via case (button at the back) |
Pay attention to the status indicators. If after all the manipulations, one earphone continues to burn red or does not respond to touch, it may not physically turn on due to a deep discharge. Leave both devices in the case with the charger connected for at least one hour.
Configuring through the application and software update
For owners of flagship and mid-budget Xiaomi models, the issue of software remains relevant. Embedded headphone software (firmware) can also contain bugs that interfere with the correct operation of the stereo mode. Updating the firmware often solves problems with connection stability.
To check for updates, connect your working headphone to your smartphone and launch the official app. In the "About device" or "Settings" section, information about the software version will be available. If the system suggests updating, make sure that the headphone charge is at least 50%, and put them in the case during the process.
⚠️ Warning: During the firmware update, it is strictly forbidden to open the case cover or distance the smartphone from the headphones. Interrupting the process can lead to a complete failure of the device (brick).
The app also has a control setting feature available. Sometimes users accidentally turn off one of the channels or change mode (for example, turn on low latency game mode, which is unstable on older versions of Android).
💡
Use only the official Xiaomi Earbuds app or Mi Wear from Google Play/App Store. Third-party apps from unverified sources may misinterpret charge and connection status data.
Diagnostics of hardware faults
If software methods, including full reset and reconnect, have failed and one earphone is still silent, it is worth considering a hardware breakdown. A common cause is oxidation of contacts. Moisture from sweat or high humidity in the room can create an oxide film on the gold headphone contacts and pins in the case.
To clean, use a cotton swab slightly soaked in alcohol or a special contact cleaner. Gently wipe the contact pads on the lower end of the headphones and the response pins inside the case. Allow the alcohol to dry completely before you put the headphones back in.
Also worth checking is the dynamic mesh. Sulfur and earwax can tightly clog the speaker mesh, creating the illusion of a breakage or a quiet sound. Use a soft brush or a special sticky tape to clean, but do not pierce the mesh with sharp objects, as you can damage the speaker membrane.
In rare cases, the plume inside the body demagnetizes or detachs when it falls, and if the earphone falls from a height and then stops working, the probability of mechanical damage is high, in which case the software reset is powerless, and repairs are required at the service center.
💡
If after cleaning the contacts, a complete reset and checking the charge, one earphone does not show signs of life, most likely, the problem is hardware in nature and requires a replacement of the battery or speaker.
