Buying TWS (True Wireless Stereo) wireless headphones often starts with the euphoria of a lack of wires and a compact case, but can be overshadowed by a technical problem when devices stop working in pairs. Users of the popular Xiaomi Redmi AirDots model often face a situation where the phone sees only one headphone, or the sound is played exclusively from one side. This does not mean that the gadget is broken, most often requires the correct reconfiguration of synchronization between the left and right module.
In this article, we will look at all the nuances of how to get your Redmi AirDots to work again in stereo mode. We will look at the procedure for a complete reset, the initial pairing algorithm and methods for solving common connection problems. It is important to understand that the setup process requires precise adherence to the sequence of actions, since the timing of the taps on the touch panels plays a crucial role here.
Before you start complex manipulations, you should make sure that the problem lies in the software failure of pairing, and not in a discharged battery. Make sure that the case and the headphones themselves have sufficient charge, because at low battery voltage, the device can behave unpredictable and refuse to go into search mode. If the charge is all right, but the sound is still coming from only one channel, you need to perform the procedure of resetting to the factory.
Preparing for setting up and cleaning the Bluetooth list
The first and most important step before any manipulation to restore communication between the headphones is to completely clear the connection history on your smartphone. If the phone has stored the old Xiaomi Redmi AirDots connection profile, the device will try to connect using old, possibly erroneous parameters. First, open the Bluetooth settings on your mobile device and find your gadget in the list of available devices.
Click on the gear icon or hold your finger on the model name to open the context menu, and select the option “Forget device” or “Unpair.” After that, it is recommended to completely turn off the Bluetooth module on the phone, wait a few seconds and turn it on again. This action will clear the cache of connection errors and prepare the smartphone to find a new device.
Now you need to put both earbuds in the charging case and close the lid for a few seconds so that they go into standby mode. Make sure that the contacts on the headphones and inside the case are clean, as oxidation or dust can interfere with charging and proper operation. Only after these preparatory steps you can proceed to directly reset the settings of the headphones themselves.

Before starting the reset, make sure that the smartphone is turned off Bluetooth to avoid search conflicts during the procedure.
The procedure for complete reset (Hard Reset) headphones
The key to solving the desynchronization problem is to perform Hard Reset, which brings the electronic components of the headphones back to factory settings, deleting all temporary files and resetting the pairing parameters between the left and right modules. First, remove both headphones from the case simultaneously, and you should see that the indicators on them will start flashing red, indicating that they are switched on.
Then you press and hold the touchpads on both headphones simultaneously. You need to hold your fingers for a long time, about 20-25 seconds, not letting them go even after the headphones turn off (the indicators go out). Continue to hold the sensors until the indicators flash red several times in a row, usually 2 or 3 times, after which they can light up white or go out again.
Once you release the sensors, put the headphones back in the case and close the lid. Wait about 10 seconds for the devices to completely shut down and save the new settings. Now take both headphones out of the case again, at which point they should start automatically looking for each other to create a stereo pair, as evidenced by the slow blinking of the indicators.
☑️ Checklist for discharge
⚠️ Warning: While holding the sensors, the headphones may issue beeps or voice commands in Chinese or English. Don't be alarmed or release buttons until the flashing cycle is complete, otherwise the reset will not occur.
Synchronization of left and right channel
Once the reset is successfully completed, the most important step is to create a stereo pair. Xiaomi Redmi AirDots headphones use technology where one channel (usually the right one) acts as a master transmitter to the second channel, and if this process is interrupted, the phone will see two separate devices or only one of them.
When you've got your headphones out of your case after you reset, don't rush to turn on Bluetooth on your phone. 10-15 So visually, you can see this by the change in the frequency of the flashing lights, if they blink fast, or if they blink constantly, then the pair is looking for a match. When the pair is created, one of the headphones (or both) will blink slowly, waiting to connect to the smartphone.
Now you can activate Bluetooth on your phone and start looking for new devices. Only one device called Redmi AirDots (or similar, without L or R consoles) should appear on the list. If you see two identical names, then the synchronization between the headphones has not occurred, and the reset procedure should be repeated, paying more attention to simultaneously pressing the sensors.
Why is the master channel important?
Diagnostics and troubleshooting connection
Even after the correct reset, there can be situations where the settings of both Xiaomi Redmi AirDots headphones are not perfect. Often users complain of a quiet sound in one of the channels or periodic connection breaks. First of all, check if the sound mesh is not contaminated. Earwax can significantly silence the sound, creating the illusion of a malfunction of the electronics.
Another common problem is the desynchronization of sound, when the audio in the left and right ears sounds with different latency, this can be due to interference in the radio channel or low battery charge of one of the modules. Try to discharge the case and headphones completely, and then charge them to 100% from another power source, for example, from a computer. USB-port, not from fast charging.
If the phone still sees two devices or doesn't see them at all, try resetting the network on the smartphone itself. Sometimes the operating system's Bluetooth stack cache may conflict with the protocols for connecting older versions of the headphones, and it's also worth checking if the phone is activated in the special features settings, as it can distort the stereo signal.
| Problem | Probable cause | Method of solution |
| :--- | :--- | :--- |
| Sees only one headphone | Couple synced not | Repeat Hard Reset, wait 15 seconds before phone search |
| Quiet sound in one ear | Grid pollution or low charge | Clean the net, completely discharge and charge |
| Intermittent sound | Interference or distance | Closer to the sound source, remove obstacles |
| Two devices in Bluetooth | Reset failure | Delete both profiles, turn off BT, repeat reset |
💡
The main indicator of success is the appearance of only one device in the Bluetooth list instead of two after the reset procedure.
Features of working with different operating systems
Setting up wireless headphones can have its own nuances depending on the operating system of your smartphone. Android and iOS users can experience different behaviors when connecting. Apple iOS devices sometimes require you to manually select the output device in the Control Point if the automatic switching does not work.
Android smartphones, especially those with MIUI shells, may have a pop-up with an animation of the connection and the charge level of each headphone separately. If that window is not available, there may be no dedicated application installed or plug-in enabled in the Bluetooth settings. However, the basic audio playback functionality should work without additional interfaces.
It’s worth noting that there’s a limit on how many devices are saved on some versions of Android, and old profiles can interfere with new connections.If you’ve changed your phone, be sure to remove Redmi AirDots from your old device before trying to connect them to a new one, as headphones can automatically try to connect to the last known gadget.
⚠️ Warning: Do not try to connect headphones to two phones at once in multipoint mode unless your Xiaomi Redmi AirDots model officially supports this feature.
Management and additional functions after setting up
Once you have managed to set up both headphones and restore the stereo mode, it is worth familiarizing yourself with the basic commands of control. Touch control in Xiaomi Redmi AirDots is implemented through single, double and triple presses, as well as retention. Usually, a single press is responsible for playing or answering a call, and a double press is responsible for switching the track or activating the voice assistant.
The pressing should be confident, but not too strong to move the earpiece in the ear. If the commands are not executed the first time, try changing the touchpoint on the earpiece by moving your finger slightly above or below the center of the touch area.
To extend the battery life, it is recommended to put the headphones in the case immediately after use. Even when they are off, they consume minimal energy, but in a closed case with magnetic fixation, they are guaranteed to go into deep sleep and start charging. Regular charging also helps calibrate the power controller.
💡
Use the original cable to charge the case, as cheap analogues may not supply enough current for the proper operation of the headphone charge controller.
