The situation when wireless headphones suddenly stop working in pairs is familiar to many owners of budget acoustics. Often users are faced with the fact that Xiaomi Redmi Airdots start playing sound on one side only, or the phone sees two separate devices instead of one headset, a common problem of desynchronization of the left and right channel, which is solved by a software reset.
Rebuilding the Right Work TWS-It doesn't require a service center or a special equipment, and in most cases, it's enough to do a sequence of simple things to force the modules to find each other. Below, we'll go through the algorithms for different crash scenarios in detail.
Before any manipulations, it is important to understand that the success of the operation depends on the battery charge. Make sure that the case and the headphones themselves are charged at least 30-40%. If the battery is completely discharged during the reset, the device may not have time to complete the initialization cycle, which will lead to a repeat of the error.
Diagnostics of the main problems of synchronization
Before we start taking drastic measures, we need to determine exactly what the malfunction is, and the behavior of the indicators on the Redmi Airdots body and the way they are displayed in the Bluetooth list of the smartphone provides the key to solving the problem, and most often, we see gadgets as "R" and "L" separately.
Sometimes the device is connected, but the audio is broadcast to only one channel, which indicates that the master mode is not activated correctly. In normal situations, one earpiece (usually the right one) is in charge and transmits the signal to the second one, and the phone is connected only to the master.
⚠️ Warning: If the headphone light flashes red and white (or blue) at high frequency, this may indicate a critically low charge or physical battery damage, rather than a software failure.
It's also worth checking if the device isn't connected to another gadget nearby. Xiaomi's Bluetooth modules have good memory and can automatically try to connect to the last active device by blocking the connection to your phone.
For an accurate status determination, look at the table below, where the indicators states are described:
| Status of the indicator | Meaning | Action. |
|---|---|---|
| Blinking white slowly | The mode of pairing (Pairing) | Search for the device in Bluetooth |
| Burning red. | Charging's coming. | Expect full charge |
| Blinks red. | Low battery charge | I need you to charge. |
| Burning white. | Headphone connected | We can use it. |
Preparation for the resetting procedure
Quality preparation eliminates most reconnection errors. The first step is to completely remove old connection profiles from your smartphone memory. Go to Bluetooth settings, search Redmi Airdots (or AirDots Basic) list, and select Forget Device or Unpair.
After that, it is recommended to turn off Bluetooth on the phone for 10-15 seconds, this will clear the cache of connections in the Android or iOS operating system. While the phone is resting, clean the contacts on the headphones themselves.
Use dry soft cloth or cotton swab to wipe the metal charging contacts on the headphones and inside the case.Oxidation or dust can prevent the correct charge, which will prevent the device from coming out of sleep mode correctly.
☑️ Checklist before reset
It’s important to make sure you’re holding the original device or a quality copy, as the reset algorithms may be slightly different. For Mi True Wireless Earbuds Basic and Airdots S models, the procedure is almost identical, but there are always nuances.
Classic Reset Method Through Touch Panels
The most common way to restore channel synchronization is to use touch panels, which works for most versions of Redmi Airdots, and you need to remove both headphones from the charger case.
Wait for them to turn on. Usually the lights should light up. Now press and hold the touch zones on both headphones simultaneously. Hold on for about 5-7 seconds until the lights go out. That means the device is off.
Do not release your fingers (or pressing again if they are already out), continue to hold the panels for more. 15-20 You'll see the lights flash red several times, then light up white, then go out again, or flash white quickly. reset_ done.
⚠️ Warning: While holding the sensor, the headphones may be emitting audible signals or voice cues in Chinese or English. Don't be alarmed or release buttons until the blinking cycle is complete.
After a successful reset, place the headphones back in the case for 5-10 seconds, then retrieve them. Now they have to go into search mode. Turn on Bluetooth on your phone and search. There should only be one device left on the list.
What to do if sensors do not respond?
Alternative method: Reset button on the case
Some modifications, such as the Redmi Airdots 2 or Airdots Pro, feature a physical button on the charging case itself, a method that is considered more reliable because it eliminates the problem of "dancing with a diamond" around the touch-sensitive headphone panels.
Put both earbuds in the charge case, but don't close the lid. Make sure they sit tight in the sockets and the lights on them are on (charging is underway). Find a circular button on the end or inside the case between the headphone seats.
Press this button and hold it for a while. 15-30 The headphones inside the case should start flashing red several times. Release the button when the blinking changes or stops. Now the device is reset to factory settings.
Remove the headphones from the case. They have to automatically try to connect to each other. If one of them flashes, and the other one is on or off, then the pair is created. If both flash, the connection is not established, repeat the procedure.
💡
For models with a button on the case (Airdots 2, Pro), it is recommended to reset when the case is connected to the charger to prevent interruption of the process due to a voltage surge.
Features of reset for Redmi Airdots 3 and Pro versions
Newer models, such as the Redmi Airdots 3 or the Pro and S versions, may have a modified logic, and in particular, they often don’t have the ability to reset simply by keeping the sensor off for a long time.
These devices often require Mi Earbuds (or the built-in MIUI/HyperOS menu) to connect your headphones to your phone, open the app, and find "Settings Reset" or "Factory Reset." This is a software method that ensures that all profiles are cleaned.
If the app doesn't work, double-switch it. Turn on the headphones, then turn them off with the sensor holding for 5 seconds. Immediately after switching off, while they're in the case or in your hands, press the sensors for 20 seconds. The controller's logic here is about timed between states.
2), which requires a more stable signal during the initial pairing, hold the headphones as close to the phone as possible (at a distance of 10-15 cm) at the time of connection.
💡
For newer models (Airdots 3/Pro), the priority reset method is to use the official Mi Earbuds app, as the hardware buttons can be reassigned by the manufacturer.
Why do headphones only work on one side?
This is the most common user complaint, and there may be several reasons, and not all of them are solved by resetting. The first is the desynchronization we described above. The second option is a software bug of the phone that remembers the wrong profile.
The third, and most unfortunate, reason is that the battery in one of the headphones fails, and if one channel is discharged faster than the other, it will shut down, ripping the stereo pair, and you can check this by leaving the headphones in the case on charge for 2-3 hours, and then measuring the time of operation.
The problem can also be the contamination of the speaker's grid, earwax can completely block the sound, giving the illusion of electronics breaking, visual inspection and careful cleaning with a soft brush often return sound without any settings.
⚠️ Warning: Don't use sharp objects (needles, toothpicks) to clean the speaker mesh. You can pierce the membrane, and then the earphone will really fail permanently.
