Sometimes wireless devices stop interacting correctly with the smartphone, and then it becomes necessary to return them to their original state. Complete reset is the most effective way to eliminate software errors when the headphones can not see each other or the phone. Owners of the Xiaomi Redmi AirDots 2 model often face channel desynchronization, which is solved by this procedure.
The recovery process does not require any special software or connection to the computer, all manipulations are done exclusively through the touch buttons on the headset body. It is important to understand that after reset, the headphones completely forget all previously paired devices, so you will have to re-do the search in the Bluetooth menu of the smartphone.
In this article, we will discuss in detail the algorithm of actions that will help to revive your gadgets. We will look at the nuances of the indication, possible problems in the procedure and how to solve them. TWS-headsets.
Signs of the need to reset the headset settings
Before you start taking drastic measures, make sure that the problem lies in the software failure. Often users try to reset when it is enough to simply clean the charging contacts.
The most common problem for the Redmi AirDots series is desynchronization, when the left and right earphones stop working in pairs, in which case the phone sees the device as one channel, and the second one either remains silent or is defined as a separate device with a similar name.
⚠️ Warning: If the indicator on one of the headphones does not light up even after a long charge, the problem may be hardware, in which case the software reset will not help, and you will need to replace the battery or repair.
Also a sign of the need to reset is the inability to pair with the new device, even if the old is out of range. There are situations when the headset “hangs” in search mode and does not respond to smartphone commands.
Sometimes, after you update your smartphone’s operating system, your old connection profiles may conflict with new security protocols. If you’ve updated your Android or iOS and the sound is gone, try resetting your headphones so they create a new, clean connection profile.
It is worth noting that periodic failures in wireless electronics are normal. Microcontrollers inside AirDots 2 can accumulate bugs in the buffer, which leads to unstable operation. Regular reboot or reset helps keep the device in good shape.
Preparation of the device for the recovery procedure
To perform the operation successfully, you need to ensure stable conditions, first of all, make sure that the battery in both headphones and in the case is sufficient. If the device runs out during the reset, it can go into deep discharge mode or lock.
Before you start manipulating, it is recommended to remove the device from the paired list on your smartphone. Go to the Bluetooth settings, find Redmi AirDots 2 and select the option "Forget device" or "Unpair pairing" This will prevent automatic connection during the process.
- 🔋 Make sure the case is at least 50% charged to ensure a stable meal during the procedure.
- 📱 Turn off Bluetooth on all nearby devices that were previously connected to this headset.
- 🧼 Wipe the metal contacts on the headphones and inside the case with dry cloth for better connection.
- 👐 Wash your hands or wipe them so that touch buttons respond to touch as accurately as possible.
It is important to place both earbuds in the charge case before starting. The indicators should light up, signaling the start of charging. If this does not happen, check the polarity of the installation: magnets should attract the headphones, and LEDs should glow red.
Some users mistakenly believe that a special application is needed to reset.In fact, Xiaomi Redmi AirDots 2 is controlled exclusively through physical (touch) buttons. No additional programs like Mi Fit or Xiaomi Wear are required for this particular model.

How to Reset Redmi AirDots 2
The process of restoring factory settings requires precision and a certain sequence of actions. The main difficulty is that the headphones must exit the case at the same time and sync with each other before you start (long press). If you break the timing, the procedure will not start.
Take both earbuds out of the charger at the same time, at which point they should start flashing red and white (or blue, depending on the revision), which means a pairing mode. Wait a few seconds until they find each other: one of the headphones should stop blinking or blinking less often, and the other should continue active display.
Sequence of action:
1. Get both earphones out.
2. wait for synchronization (blinking slows down).
3. Press and hold the sensors for 5-10 seconds.
4. Wait for the blinking 3-4 times.
5. Release the sensors.When you see that the headphones are connected together (usually seen by the change in the frequency of flashing indicators), you need to press the touch buttons on both headphones at the same time. You need to hold for about 5-10 seconds until the indicators flash red several times (usually 3 or 4 times) and do not go out or go into another mode.
Once the lights have blinked and gone, put the headphones back in the case, close the lid (if you have one), or just leave them in the case for 5-10 seconds, which will complete the reset cycle, and now, once you have them out again, you will see that they have gone into fast pairing mode, as if you just bought them from the store.
⚠️ Attention: Press the sensors confidently, but without undue effort. Too much pressure can damage the inner membrane of the speaker or the sensor module itself.
If you don't get it the first time, don't despair. Bluetooth Low Energy sometimes fails to sync. Try repeating the procedure by paying more attention to the time when the headphones are lying next to each other outside the case before pressing the buttons.
What to do if the timing does not match?
Table of indications and operating modes
Understanding the color signaling of LEDs is critical to diagnosing the condition of Redmi AirDots 2. Different blinking modes inform the user of the current status of the device, whether it is charging, pairing or error.
The table below shows the main indicators states you may encounter during operation and reset. Pay attention to color combinations, as they are key to understanding what is going on inside the device.
| Status of the indicator | Colour | Mode of work | User action |
|---|---|---|---|
| It's burning all the time. | Red. | Charging's coming. | Waiting for full charge |
| Gasnet | Red. | Charging complete. | We can use it. |
| Slow blinking | White/Blue | Interconnection mode | Searching in Bluetooth smartphone |
| Fast flashing (2 times) | Red. | Mistake/Dumping | Repeat the procedure or charge |
| Single flashing | White | Incoming challenge | Double press for a response |
It is worth considering that different batches of Xiaomi can use LED indication of slightly different shades. However, the logic of the work remains the same for the entire line of TWS devices of this manufacturer. Red almost always means charging or low energy, and white / blue – active work.
If you see chaotic flashing in different colors, this may indicate a deep discharge or a malfunction of the controller, in such cases, it is recommended to leave the device on charge for several hours before trying to perform Hard Reset.
Post-resetting and troubleshooting
After the successful reset procedure, the headphones go into active search for a new device. On the screen of your smartphone, the name Redmi AirDots 2 (or simply AirDots 2) should appear on the list of available Bluetooth devices.
Click on the name of the pairing device. In some cases, the system may request code confirmation, but for this model, it is usually enough to simply click "Connect." If the connection is successful, you will hear a voice message "Connected" or a characteristic beep.
- 📶 If the phone can’t see the headphones, make sure you’re less than 1 meter away from them.
- 🔄 Try turning off and on Bluetooth on your smartphone again.
- 🔋 Check if the headphones are discharged during the reset procedure.
- 📱 Make sure that the smartphone is not enabled mode "In the plane".
There are times when the headphones are connected, but the sound is only coming from one channel or not at all, in which case, in the Bluetooth settings on the smartphone (in the Device Information section or the gear next to the name), you need to check the sound balance, sometimes it helps to remove the device and re-pair.
⚠️ Warning: Do not connect your headphones to public Wi-Fi networks or suspicious devices while pairing.While the risk of hacking is minimal, connection security should always be a priority.
If the channel desynchronization problem (where the sound is only on the left or right) recurs after the reset, it may be the firmware version. However, for Redmi AirDots 2, it is not possible to manually update the firmware by the user, since this is a simplified model without support for an update application.
💡
When pairing again, always delete the old Redmi AirDots 2 profile from your phone’s memory, even if it’s marked “Not connected.” MAC.
Frequent errors in the discharge
Despite the simplicity of the instructions, many users make common mistakes that reduce all efforts to zero, the most common of which is the late removal of headphones from the case, and if you pull them out within seconds of each other, they may not be able to sync with each other.
Another common mistake is not holding the touch buttons enough, where users let their fingers go immediately after the first blink, thinking that the process is complete, in fact, to activate the reset mode, you need to hold the buttons until a series of quick blinks (usually 3-4 times), which takes about 10-15 seconds.
It's also common to ignore the charging state, and if the case is discharged, it may not signal to the headphones that they're "at home," and as a result, the headphones think they're still in the work, and they don't reset when they're placed in the case.
Sometimes the problem is oxidation of the contacts, and moisture from sweat or water can create an oxide film on the contacts, which disrupts the electrical contact between the case and the earpiece, which can be visually imperceptible, but it functionally blocks the work.
💡
The key to success is synchronization. Both earbuds must be removed and clamped at the same time, otherwise the TWS protocol will not start reset mode.
Preventing and caring for Xiaomi Redmi AirDots 2
To avoid the need for frequent resets, you should use the device correctly. Avoid deep battery discharge. If you do not plan to use headphones for a long time, charge the case at least once a month.
Regularly clean the speaker mesh and charging contacts. Earwax and dust can clog holes, which leads not only to deterioration of sound, but also to overheating and malfunctioning of electronics. Use a soft dry brush or cotton swab lightly moistened with alcohol (without getting inside).
Keep your headphones dry, away from sources of strong electromagnetic radiation, such as microwave ovens or powerful routers. Although current Bluetooth standards have good interference protection, prolonged exposure to aggressive environments can affect the stability of the connection.
Don't drop the device and avoid impacts. Inside the Redmi AirDots 2 are miniature components that can be soldered without mechanical impact, and even if the body is intact, the antenna contact may have moved away inside.
Keeping these simple rules will prolong your headphones and ensure a stable sound quality. Remember, electronics like accuracy and regular maintenance. If problems persist after all the manipulations, it may be time to consider buying a new pair.
