What to do if the wireless headphones Xiaomi Airdots are unwinded

When the left and right headphones Xiaomi Airdots stop seeing each other, is one of the most common problems owners of this model. users often face the fact that when removed from the case, the device connects to the smartphone as two separate gadgets or only one side works, a phenomenon known as channel desynchronization, causes panic, but is actually solved by fairly simple manipulations.

The most common cause of failure is a software glitch of the Bluetooth protocol or accidental tapping of touch panels when extracted. In rare cases, the culprit is a discharged battery in one of the modules, which prevents it from waking up and finding a pair. It is important to understand that hardware failure is extremely rare, and in 95% of cases, a software reset helps.

In this article, we will discuss in detail the algorithm for reconnecting between modules. Reconnection requires strict adherence to the sequence of actions, since press timings are critical. Don't rush to bring the device to the service, try to perform the calibration instructions yourself.

Diagnosis of the problem: why does desynchronization occur

Before you start to act, you need to understand the nature of the conflict. Redmi Airdots wireless headphones and their counterparts use TWS (True Wireless Stereo), where one channel is the master and the other is the plume. If the communication between them is broken, the smartphone sees two devices with the same name or only one of them.

A common cause is one of the headphones getting stuck in standby or mating mode, which could happen if you took them out of the case at the same time or held your finger on the sensor for too long, and it also affects the presence of old connection records in the smartphone's Bluetooth list that conflict with the new communication session.

⚠️ Warning: If one of the headphones is discharged to zero, it will not be able to sync with the other. Make sure that both modules are charged before starting the reset procedure.

For a good diagnosis, look at the indicators, and if you extract one lights red and the other flashes white quickly, there's no connection. Normally, they have to blink quickly and leave one light flashing slowly, waiting to be connected to the phone.

Full reset (Hard Reset) headphones

The most effective way to restore work is to completely reset to factory settings, which clears the modules' internal memory of old pairing profiles and forces them to re-search each other, and it doesn't require additional tools, just your fingers and a little patience.

First, put both earbuds in the charge case and close the lid. Let them lie there for 5-10 seconds so they go into charging mode and forget the current state. Then remove both devices at the same time. Both modules should light up the indicators.

Now you need to do a series of taps. Press the touchpads on both headphones simultaneously and hold for about 20 seconds. The indicators should flash red several times before going out. This means that the reset was successful. If the indicators are not responding, maybe the sensor was not activated, try again, making sure that the touch is tight.

After a successful reset, the indicators should start flashing white quickly, signaling a pairing mode. Don't try to connect them to the phone right now. First wait until they find each other: one of the indicators should stop flashing or flashing less often while the second continues an active search.

Removing old profiles and re-pairing

A critical step is to clean the list of paired devices on your smartphone. If the phone has an old Xiaomi Airdots profile in its memory, it can automatically connect to one module, ignoring the second, which leads to desynchronization.

Go to your smartphone’s Bluetooth settings. Find your headphones (they may be called Airdots) in the list of devices, Airdots_R or MI True Wireless EBs. Click on the gear icon or information icon and select "Forget device" or "Disable." Repeat this for all records related to these headphones.

⚠️ Warning: After removing the device, be sure to turn off Bluetooth on your smartphone 10-15 This will reset the cache of the phone's radio module.

Now you can start pairing. Turn on Bluetooth on your phone and start looking for new devices. Headphones should be in standby mode (fast blinking). When one device with the right name appears on the list, click on it to connect. If it's successful, the phone will only see one gadget and the sound will be stereo.

Specific models: Airdots, Redmi Buds and Pro versions

Different versions of the lineup can have nuances in control, such as the Airdots 2 or Redmi Buds 3 Lite, which can be more sensitive, and some versions, such as the Airdots Pro or Air 2, use physical legs instead of touch control that you need to press.

For models with physical buttons, the reset procedure is similar: hold the buttons on both headphones until the color of the indicator changes. However, retention time can vary from 5 to 10 seconds depending on the firmware. The table below shows the main differences in the indication for different versions.

Pro and Air owners should be more careful with timings, as these devices have more complex logic and respond faster to commands. A sequence error can lead to pairing with a new phone instead of resetting.

Use of Mi Home App and Software Update

For advanced users and owners of the Xiaomi ecosystem, there is the ability to control headphones through the Mi Home app or Xiaomi Earbuds. Connecting through the app allows you not only to check the charge, but also, more importantly, to update the software.

Often, the problem of desynchronization is solved by updating the firmware. Developers regularly released patches that correct connection errors. Go to the application, find your headphones in the list of devices and check for updates. If the version of the software is relevant but the problem persists, try to find the item “Reset Settings” in the application menu (if available for your model).

Sometimes, flashing through reset and re-registration in the app helps. Once you remove your device from Bluetooth and reset your headphones, don't connect them through the phone's standard menu. Launch the Mi Home app, click Add Device, and follow the on-screen instructions. This method ensures that the master channel is properly configured.

💡

Use the official Xiaomi Earbuds app to check the firmware version. Third-party apps from the Play Market often show wrong battery power and don't have access to update features.

Cleaning contacts and case maintenance

The physical side of the matter is not to be forgotten: Contacts on headphones and inside the charging case tend to oxidize or become contaminated with earwax and dust. If the contact is poor, the earphone in the case may not charge or go into reset mode when the cover is closed.

Take a cotton swab lightly soaked in alcohol or a special electronics cleaner, and gently wipe the golden contacts on the lower ends of the headphones. Also blow or wipe the indentations in the case itself. Make sure that when you install the headphones in the case, the indicators light up, signaling the start of charging.

Check if the magnets fit tightly. If one of the headphones is walking in the socket and not being magnetized, it won't receive a signal to turn off or reset when the lid is closed, which is a common reason why one channel stays active and the other goes off, upsetting the balance.

Possible hardware malfunctions

If none of the software methods worked, and the headphones still work only separately or do not see each other, there is a high probability of hardware failure, most often the Bluetooth module inside one of the headphones or its antenna fails.

Symptoms of hardware failure can be: no response to charging, no glow of the indicator even after a long stay in the case, or heating one of the modules, in such cases, the program reset is powerless, because the problem lies in the "hardware".

⚠️ Attention: It is not recommended to open the headphones yourself, they are monolithic and glued together, and any attempt to open the headphones will lead to irreversible damage to the body and battery.

In case of suspected battery or module breakdown, the only reasonable solution is to contact an authorized service center or replace the device if the warranty period has expired.

💡

If after a complete reset, clear contacts and reconnect the headphones do not sync for 3 attempts, most likely, one of the modules is defective.
