The situation when the loved ones TWS-The headphones suddenly stop plugging in or playing the sound that many owners of the Xiaomi ecosystem know, and users often find that the device simply doesn't turn on, doesn't see the phone, or only one side is working, and this can happen for a variety of reasons: From the banal discharge of the battery to complex software conflicts of the Android or iOS operating system.
In most cases, the problem is software-based and solved in minutes without going to the service center. It's important to not panic and consistently rule out all possible factors that affect the stability of a wireless connection.
In this article, we will take a closer look at diagnostic algorithms for popular models such as Xiaomi Mi True Wireless Earbuds, Redmi AirDots and Haylou. You will learn how to force resets, update firmware through the app and what to do if components fail.
The main reasons for the failure of the Bluetooth connection
The first thing to do is to understand why the Bluetooth module stopped transmitting the audio stream correctly. Often the culprit is not the headset itself, but the pairing cache in the smartphone. The system can remember old configurations that conflict with the current communication session, in which case the phone sees the device but cannot establish a connection.
💡
Before a deep diagnosis, make sure that the smartphone is turned on GPS-module, as in Android it is necessary for Bluetooth scanning.
Another common cause is interference on the air, and if you're in a place with a lot of Wi-Fi routers or active Bluetooth equipment, the signal may be silenced, and it's also worth checking if the phone's settings are power-saving, which force the background processes to shut down.
- 🔋 Complete depletion of charge in one of the headphones or charging case.
- 📱 Overflowing list of stored devices in smartphone memory.
- 📶 Physical obstructions or radio interference in line of sight.
And don't ignore the physical state of the contacts, because if you use your gadget in the gym or outdoors, the charging contacts could oxidize the metal or get sweat, which leads to the fact that the device does not charge, even if it is in a case.
Problems with charging and indicators
People often wonder why the shaomi bluetuz headphones don't work even though the lights are on, because the LED can signal a voltage in the battery, but its capacity may not be enough to start the Bluetooth protocol. Lithium-ion batteries tend to degrade, especially if the device has been lying unused for a long time.
⚠️ Warning: If the indicator flashes red or doesn't light up at all, try cleaning the contacts with a dry cotton cotton disc soaked in alcohol.
Check the charging cable and adapter. Using cheap power supplies with unstable current can damage the charge controller inside the case. In this case, Mi True Wireless Earphones may stop responding to the network connection.
☑️ Diagnostics of nutrition
It's important to pay attention to the color of the indicator. If it's white or red, but it doesn't blink in pairing mode, maybe the problem is that the power controller is software-based, and in such a situation, simply charging it won't be enough, you'll need a full reboot procedure.
How to reset the headphone settings Xiaomi and Redmi
If a software failure interferes with normal operation, the solution is to reset to factory settings, which removes all stored pairs and returns the firmware to its original state. The procedure may differ from model to model, but the general principle remains the same.
For most models, including the Redmi AirDots and Mi Air 2, you need to remove both headphones from the case. Then press the touchpads or physical buttons on both devices simultaneously. Hold them for 10-15 seconds until the indicators flash red several times.
Once the display goes out, put the gadgets back in the case and close the lid. In 10 seconds, open the case again. Now the device is ready for a new pairing. Remember to delete the old headset entry in your phone's Bluetooth menu before reconnecting.
Specificity of reset for different models
Working with Xiaomi Earbuds and MIUI
Owners of smartphones based on MIUI or HyperOS have access to advanced features through the application Xiaomi Earbuds. Here you can check the relevance of the version of the software. If headphones shaomi bluetuz do not work correctly, the firmware update often solves the problem of desynchronization of the left and right channels.
Go to Bluetooth settings, find your device, and click on the gear icon. If you have an update, the system will suggest you install it, and it's important to keep the case open and the headphones off to ensure a stable communication channel.
Also in MIUI settings, there is a Battery Optimization feature, so you can find "Bluetooth" and "Xiaomi Earbuds" in the list of applications, set "No Limits" mode, and this will prevent the background sound transmission from being killed by the energy saving system.
| Model | Type of discharge | Indication | Retention time |
|---|---|---|---|
| Redmi AirDots | 15 seconds buttons | Red flashing | 15-20 seconds |
| Mi Air 2 / 2S | Double touch. | White flashing | 2 times 5sec. |
| Haylou GT1 | Triple touch. | Red/Blue | 3 times fast |
| Mi Noise Cancelling | Power button | Orange | 10 seconds. |
Hardware malfunctions and physical wear
When software methods are powerless, consider a physical breakdown: a dynamic head can be damaged by moisture or impact; if the sound becomes quiet, hoarse, or disappears completely on only one side, the plume is likely to break or the speaker will fail.
Moisture is the main enemy of electronics. Even if IPX4 is claimed to be protected, it's only spray protection, not immersion protection. Sweat entering the enclosure causes contact corrosion, and in such cases, professional cleaning is required in the service.
Also, look at the condition of the case, if it stopped charging the headphones, it may have failed its internal battery or the voltage converter board, and you can check this by connecting the headphones to charge directly (if the design allows) or replacing the cable.
What to do if one earphone does not work
The situation when only one headphone works is a classic one. TWS-It's called desynchronization, and the left and right channels have lost communication with each other and are independent, and to fix that, you have to pair them back together.
Remove the device from the Bluetooth list on your phone. Put both earbuds in the case, close the lid. Open the lid and, without removing them, press and hold the buttons (or sensors) until the indicators light up with a certain color indicating the pairing mode between them, usually a quick flashing of white.
💡
The main condition for successful recovery of the pair – both headphones must simultaneously enter the reconnection mode, so press timing is critical.
Then you can search the devices on your phone again. If you have persistents, try connecting the headset to another smartphone. If there's only one channel, it's the hardware.
