Modern wireless headphones, such as the Xiaomi Redmi AirDots, are often delivered to the user already configured to work in stereo mode. However, during operation, you may experience a situation when the right and left headphones stop “hearing” each other or connect to the phone as two separate devices, this is not a breakdown, but a synchronization failure that is easy to fix.
To restore the device to full operation, you need to force the left and right modules to pair each other before connecting to the smartphone. Resynchronization takes only a couple of minutes, but requires strict adherence to the sequence of actions, ignoring this stage leads to the fact that music plays in only one ear.
In this article, we will discuss the algorithm of actions for models AirDots, AirDots S and AirDots 2. You will learn how to reset the settings to factory, correctly initiate the search for a pair and avoid common errors during the initial activation.
Preparing for synchronization and resetting settings
Before starting the procedure, it is important to completely clear the connection history on your smartphone. If the phone has a profile "Mi True Wireless EBs Basic R" or "Redmi AirDots", it must be deleted, otherwise the device will try to connect to old, possibly damaged parameters.
⚠️ Warning: Don't just turn off Bluetooth, but follow the command "Forget the device" or "Delete" in the list of associated gadgets. After that, turn off the Bluetooth on the phone completely so that it does not interfere with the setup process.
The next step is to physically reset the headphones themselves, so put both modules in a charging case, make sure the contacts fit tightly into the magnets, and the lights turn red to signal the start of charging. If the lights don't burn, wipe the contacts dry.
Now you have to remove both headphones from the case at the same time, and they have to light up the indicators (usually red or white, depending on the model), press the touchpads on both devices and hold them for about 20 seconds, the indicators have to flash red several times and go out, which means that the reset to the factory settings is successful.
☑️ Checklist before pairing
Algorithm of pairing left and right earphone
Once you've successfully reset, the most important step is to put both of these headphones back in the charger case and get them out again, and they're now in standby mode, and unlike normal activation, you have to wait until they find each other.
Usually one of the indicators (most often the right one) flashes white slowly, and the other (left one) flashes quickly, which means that you're looking for a pair. In 5-10 seconds, the blinking should synchronize: both indicators will flash white slowly and equally, and this is a signal that the stereopara is created.
What to do if the indicators flash differently?
Only by making sure that both earbuds flash slowly and synchronously can you turn on Bluetooth on your smartphone. If you start searching for devices earlier, the phone can see two different signals and connect to only one, leaving the second behind.
Turn on Bluetooth on your phone and click "Search for New Devices." One device should appear on the list: Redmi AirDots or Mi True Wireless EBs Basic R. Click on it to connect. After successful docking, the voice assistant will report status (usually by "Connected" or "Channel Right/Left").
Features of AirDots S and Redmi AirDots 2
While the whole Xiaomi TWS lineup is similar, the AirDots S and AirDots 2 series have some nuances with the display. These versions have different LEDs and colors, for example, waiting for pairing, the indicator can burn red, and when successfully connected to the phone, it can go out or change color to green.
It's important to understand that in these models, the master device is most often the right earpiece, which sends the signal to the left, so when you reset, it's sometimes recommended that you activate the right module first and then the left one first, although the method of simultaneous extraction from the case also works in 90% of cases.
- 🎧 AirDots S: The indicator flashes red and white alternately when paired.
- 🎧 AirDots 2: May require longer sensor retention (up to 30 seconds) to reset completely.
- 🎧 Common models: Use standard Bluetooth 5.0 protocol, which provides stable communication.
If you have an AirDots 2, check out Mi True Wireless Earbuds Basic 2 (or similar for your firmware version) and check each headphone separately and update their software, which often solves the problem of desynchronization.
Problem Solving: Phone Sees Two Devices
One of the most common problems is that the smartphone sees two devices with the same name, like two Redmi AirDots, which is a classic sign that the headphones are not paired with each other, but work independently in mono mode.
To solve this problem, you need to reset again, as described in the first section, but with one important addition: After extracting from the case and before pressing the buttons, make sure that the headphones are not connected to any other devices in range. Sometimes they can "cling" to the tablet or laptop, interfering with pairing.
⚠️ Warning: If your phone sees two devices, never try to connect them in turn, this will fix the error in the memory of the phone's Bluetooth module. First, make sure that only ONE device is displayed in the search.
It’s also worth checking if Multi-Point or similar settings are enabled in the phone itself, which can prioritize multiple connections. In rare cases, clearing the Bluetooth cache in Android settings helps: Settings → Apps → Show System → Bluetooth → Memory → Clear the cache.
Table of indicators and their significance
Understanding color is key to successful customization, with different colors and blinking frequencies informing the user of the current status of the device, and the summary table for most models of the lineup below.
| Status of the indicator | Colour | Meaning |
|---|---|---|
| Constant burning. | Red. | Headphone in case, charging. |
| Slow blinking | White | The mode of pairing (Pairing Mode) |
| Fast blinking. | White/Red | Finding a device or resetting settings |
| Short blinking | Green. | Successful connection to the sound source |
Note that some Xiaomi revisions may have different colors, such as using blue instead of white to indicate an active Bluetooth connection. Always focus on the instructions that come with the specific version.
💡
Expert advice: If the indicators are behaving strangely (e.g., flashing purple or yellow), try to completely discharge the case and headphones, and then charge them to 100% without interruption.
Connection and sound problems
Even after successful pairing, there may be artifacts of sound, such as stuttering, interrupting, or a quiet sound in one of the headphones, often not due to a breakdown, but to interference in the air or low battery power. Make sure that both earphones are evenly charged.
Another reason is the speaker's mesh contamination, and earwax can clog the hole, giving the illusion of a quiet sound or no sound at all, and gently clean the mesh with a dry toothbrush or cotton swab, without using alcohol that can damage the membrane.
- 📶 Wi-Fi interference: Routers run at 2.4GHz, just like Bluetooth.Stand away from router when setting up.
- 📱 Android Version: Older versions of Android (below 7.0) may have codec stability issues.
- 🔋 Low charge: With less than 20% charge, the transmitter power decreases, which impairs communication between headphones.
If you only have sound in one headphone after all the manipulations, check the channel balance in your smartphone's special features settings. The path usually looks like this: Settings → Special features → Hearing → Sound balance. The slider should be strictly in the center.
💡
The main conclusion: 95% of problems with headphones Xiaomi solved by a complete reset (20 seconds of clamping) and re-pairing without connecting to the phone at the time of reset.
