The situation when the beloved Xiaomi Airdots suddenly stop responding to commands or disappear from the list of available devices, familiar to many owners of budget acoustics. Often users are faced with the fact that one earphone is working and the second is silent, or the phone simply does not see the headset, despite full charging, this can be caused by a software glitch in the Bluetooth protocol, and the battery discharge of one of the cases.
Before you panic and carry the device to the service, you need to conduct a basic diagnosis. In most cases, the problem lies in the desynchronization of the left and right channels or crowded memory pairing smartphone. TWS-Headphones are complex microcomputers, and they also need periodic reboots to work properly.
We'll look at all the possible causes, from simple discharge to complex firmware failures, and you'll learn how to force resets to factory settings and reconnect modules, and the key is to act consistently without missing a single step of instruction.
Basic diagnostics and charge check
The first thing to do is to eliminate the banal lack of power. Sometimes the indicators on the case can misleadingly show the presence of charge, when in fact the voltage has dropped below the critical level for the Bluetooth module to work. Put the headphones in the charging case and leave them for at least 30-40 minutes, even if the indicators say otherwise.
Note the contacts. In Redmi Airdots and Mi True Wireless Earbuds, the contact areas are often oxidized or contaminated with earwax, which prevents normal charging. Wipe the golden contacts on the headphones themselves and inside the case with a dry cotton swab or cloth soaked in alcohol.
⚠️ Attention: If the headphones still don't light up when you put them in a case after cleaning the contacts, try pressing your fingers slightly to ensure close contact. In cheap models, spring mechanisms can fall into the air.
It is also worth checking the charging cable itself and the power supply. Using too powerful fast-charging adapters (for example, from a laptop) sometimes causes a protocol conflict, and the case simply refuses to take current. USB-computer port or power supply unit 1A.

Problems with the Bluetooth module of the smartphone
Often the culprit is not the headset, but the smartphone itself. Android and iOS operating systems periodically accumulate errors in the Bluetooth connection stack. If a phone has many old devices stored in memory, the new search may not be correct.
You need to reset the entire list of paired devices. Go to Bluetooth settings, find your Xiaomi Airdots (they can be displayed as Redmi AirDots, Mi True Wireless EBs Basic or just TWS) and click "Forget device" or "Unpair pairing." After that, you want to restart the phone itself.
In some cases, network resets help.This action will delete all stored Wi-Fi passwords and Bluetooth pairs, but often solves problems with an unstable connection.The path to the function is usually in the Settings menu → System → Settings Reset → Wi-Fi, mobile networks and Bluetooth reset.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Phone can't see headphones | The pairing mode is not activated | Press the buttons for 20 seconds. |
| Only one connects. | Rassynchronization of stereo pair | Reset to factory settings |
| Frequent cliffs of sound | Interference or low charge | Recharging and relocation |
| No sound in the game/video | Not selected A2DP profile | Switch to Bluetooth settings |
💡
When searching for a device, keep your smartphone at a distance of no more than 10-15 cm from the case. The antennas in Xiaomi budget models are very weak and sensitive to obstacles.
Complete Reset (Hard Reset)
If simple methods don't work, you'll need to do a hard reset of the headset settings. TWS-Factory-grade headphones, erasing all previous connections, a procedure that is mandatory if the headphones are no longer synchronized with each other (only the left or only the right is working).
First, put both earbuds in the charge case. Make sure they're magnetized and the lights are red (charging) Now you need to remove both earbuds at the same time. At that point, they should start flashing white, waiting for the connection.
There are two main reset methods, depending on the firmware version of your Xiaomi Airdots:
- 📱 Touch button method: Press the touch zones on both headphones simultaneously and hold near 20 The indicators should flash red. 3-4 It's a signal of a successful reset.
- 🔘 Physical Knock Method (for older versions): Some models (such as the first Airdots) need to press the buttons on the out-of-ear headphones 5 seconds before turning off, and then clamp again for 20 seconds until triple blinking.
⚠️ Warning: During reset, do not put the headphones back in the case and do not bring them close to the phone, which automatically tries to connect them.
After a successful reset, remove the device from the Bluetooth list on your phone again and start the search. Now the headphones must be identified as a new device.
What if the reset didn’t help the first time?
Dissynchronization of the left and right channel
One of the most common problems TWS-The headset is a loss of communication between the two, in which case the phone sees two devices with the same name or only one, and the sound is only in one ear, which means that the master earpiece (usually the right one) does not transmit a signal to the salve earpiece (left earpiece).
To restore the stereo pair, you need to re-introduce the headphones to each other. Take both devices out of the case. Quickly press 5 times on the touchpad of each headphone (or pinch, depending on the model) so that they turn off. Then activate them again.
Wait until one of the headphones (usually the right one) blinks slowly, and the other (left one) blinks quickly or stops blinking altogether, which means they found each other, and then you can connect to the phone.
It's important to understand that Bluetooth doesn't always handle reconnections correctly, so if you connect to your phone and the headphones go to sleep, the next time you turn on, they might try to connect to the phone, forgetting about each other, and in such cases, turning off Bluetooth on your phone before removing the headphones from the case helps.
Specificity of connection to different devices
Xiaomi and Redmi devices can behave differently with phones of different brands. Mi and POCO smartphones often pop up branded connection window with animation and the level of charge of each headphone. Other Android smartphones and iPhones will not have this window, which can confuse the user.
On iOS, devices often appear simply as "Headphones" or "TWS," without detailing the model. If the iPhone doesn't connect, try going to Settings → Bluetooth, clicking on the "i" icon next to the device (if it's on the list) and selecting "Forget this device."
On Windows computers, the problem may be in the Bluetooth adapter drivers. Make sure there are no errors in the Device Manager. Also, Windows sometimes doesn't see the headset in pairing mode if it's already connected to a phone with active Bluetooth.
💡
Cross-platform compatibility of Xiaomi Airdots is high, but for initial setup and reset it is better to use an Android smartphone, as it gives more control over the pairing process.
Program conflicts and applications
Sometimes the problem is not with the system, but with the application, for example, messengers or navigators can intercept the audio channel without giving it back, check if you have a Spotify, YouTube or voice recorder running in the background.
There is a Mi Earbuds app (for Android) to manage advanced features (equalizer, firmware update, tap settings). If the headphones don't connect, try installing this app. It can find the device even when the system Bluetooth doesn't notice it and suggest updating Firmware.
Updating the firmware is a powerful problem-solving tool, and the control controller is reprogrammed during the upgrade process, which often eliminates software bugs. However, never interrupt the upgrade process if the case or headphone charge level is below 50%.
