Modern wireless headsets from Xiaomi and its sub-brands like Redmi and QCY have gained popularity due to their excellent value for money. However, like any electronics, they can experience software failures when one of the audio channels stops working or headphones stop seeing each other, a common problem faced by owners of AirDots, Earbuds Basic and newer versions.
When the left or right earphone is not connected, it is usually solved by a software reset or the correct sequence of actions when mating. In this guide, we will examine not only standard methods, but also nuances that are often missed in official instructions. Recovery of synchronization requires care, but it does not take long if you follow the algorithm.
Before you start complex manipulations, you should make sure that the problem is not the banal discharge of the battery of one of the modules. Often it happens that the main module works, and the auxiliary simply went into a deep sleep due to low charge, so the first step should always be a thorough check of contacts and a full charge of the case.
Preparing devices for synchronization
Before any reconnection action begins, the headset and smartphone must be prepared. The cleanliness of the contacts is critical in transferring power and data between the case and the modules themselves. If the charging contacts have oxidation or dust on them, the device may not charge, leading to a connection error.
- 🧹 Carefully wipe the golden contacts on the headphones themselves and inside the charging case with a dry soft cloth.
- 🔋 Make sure the charging case has a sufficient charge level to work.
- 📱 On your phone in the Bluetooth menu, find the old connection and select the option “Forget device” or “Delete».
It is important to completely disable Bluetooth on the smartphone before starting the reset procedure.This will prevent automatic reconnection to one of the modules during the setup process. Android and iOS can aggressively try to restore the connection, which will prevent the correct start of the mating procedure.
⚠️ Warning: Do not try to connect the headphones while they are inside the charging case. Removal should occur strictly after activation of the pairing or reset mode, depending on the model.
Standard procedure for connecting new devices
For new devices that have not been paired with any gadget before, the process is as simple as possible. Once removed from the package, both modules usually automatically go into search mode. However, if you buy a headset not for the first time, the logic may differ.
Remove both earbuds from the case at the same time. The indicators should light up to signal the start of work. If only one light flashes, then the synchronization between the left and right modules is not yet established, in which case you need to wait until they "find" each other, which usually takes 3 to 10 seconds.
Once the lights start flashing blue (or flashing red and blue, depending on the model), you can turn on Bluetooth on your phone. The name of your headset will appear on the list of available devices, such as the Mi True Wireless EBs Basic or Redmi Buds 3 Lite.
Instructions for resetting and reconnecting (Hard Reset)
If the standard connection is not working, or one earphone is silent, you need to perform a full reset (Hard Reset), which forcibly removes all previous settings and causes the modules to re-find each other.
Most AirDots and early Earbuds models use a mechanical method, so you need to pinch the touch areas on both headphones simultaneously, and hold them long enough, usually for about 20 seconds, until the lights flash red several times.
☑️ Checklist for headphone reset
More modern models, such as Xiaomi Buds 3 or Redmi Buds 4, can have a reset button on the case itself, in which case you need to place the headphones inside, open the lid and hold the functional button on the case case case for about 10 seconds.
| Model of the device | Resetting method | Indication of success | Retention time |
|---|---|---|---|
| AirDots / EBs Basic | Hold the sensors on both. | Triple red flashing | 20 seconds. |
| Mi True Wireless 2 | The button on the case | White flashing | 10 seconds. |
| Redmi Buds 3 Lite | Clutch sensors 5 times | Fast blinking. | Push series |
| Xiaomi Buds 3 Pro | The button on the case | Orange light | 10 seconds. |
After the reset, be sure to place the headphones back in the case and close it on the 10-15 It allows the system to restart and fix the new settings, and then you can retrieve them to reconnect to the phone.
Solving the problem of channel desynchronization
A common problem is when the phone sees the device, but the sound comes from only one channel, or the left and right headphones work independently (playing different music). TWS-The connection (True Wireless Stereo) between the modules themselves is broken, and the phone is connected to only one of them as a mono headset.
To correct this condition, you need to "sever" the phone's connection to the headphones. Remove the device from the Bluetooth list on the phone. Then perform the reset procedure described above. The key here is not to turn on Bluetooth on the phone immediately after the reset.
⚠️ Attention: The main mistake users make is to turn on Bluetooth before the headphones have time to sync with each other. The phone can "capture" one module before it finds a "partner».
The correct algorithm of actions: perform a reset, put the headphones in the case, close the lid, wait 10 seconds, remove both headphones, wait for them to blink each other (usually one flashes quickly, the other slowly, then both start blinking the same), and only then turn on the search on the phone.
Why is this happening?
Use of the Xiaomi Earbuds app
For Android smartphone owners (especially Xiaomi and Redmi), Xiaomi Earbuds (formerly Mi True Wireless) is a real salvation, allowing you not only to manage the settings, but also to diagnose the state of each module separately.
Download the app from Google Play or Mi GetApps. Once you connect the headset (even if only one channel is running), the app can show the charge of both modules. If the app sees both headphones but the sound goes to one, try finding the reset or flash function in the app settings.
The app also features headphone search and firmware updates, often fixing connection bugs that cannot be fixed by a simple reset, a process that takes several minutes and requires a stable Internet connection.
💡
Tip: If the app doesn’t see the headphones, try connecting them to another smartphone with the app installed, reset there, and then reconnect to your phone.
Common Errors and How to Resolve Them
Even if you follow all the instructions, there can be specific problems, such as a phone seeing a device but writing "Power error" or "Unable to hide," which can be due to overflowing memory of the phone's Bluetooth module.
In such cases, it is recommended to clear the list of all previously connected devices in the Bluetooth settings, leaving only the necessary ones, and it is also worth checking whether flight or power saving mode is turned on, which can limit the operation of wireless modules.
- 📶 Make sure you are close to the phone (up to 1 meter) while pairing.
- 🔄 Reboot your smartphone before trying to connect.
- 🔋 Check if the protective film is removed from the contacts on new headphones (a frequent error when first turned on).
If nothing helps, it may be a hardware problem, check if the "problem" headphone is charging, if the indicator does not light up when placed in the case, the contacts may be contaminated or the battery may have failed.
💡
If after all the procedures of resetting and cleaning contacts, one earphone still does not respond, a hardware malfunction is likely, requiring treatment in the service center.
