Sometimes wireless headphones are unpredictable and standard control methods are not working correctly. Users often face a situation where one headphone stops syncing with the other or the device does not see the smartphone when searching, in such cases, a complete system reboot or factory reset helps, which allows you to eliminate software errors.
Xiaomi AirDots 2 (also known as Redmi AirDots) doesn’t have a separate power button or reset button on the body. The whole control logic is tied to touch panels and charging case automation, which is why the recovery procedure requires a strict sequence of actions, which we will discuss in detail in this article.
Recovery is not a complicated process, but it requires attention to detail. It is important to understand the difference between a simple shutdown and a full reset, because these actions solve different problems. Below we will discuss all the nuances of working with touch control and charging module.
Why the headphones stop working properly
A wireless headset can be disrupted by a variety of factors, from software conflicts to physical interference, and most often the problem is that the left and right channels are desynchronized when they start to work as two independent devices, in which case the sound can only come from one earbud, and the microphone stops transmitting the voice of the interlocutor.
Another common cause is an overflow of internal Bluetooth buffer memory, where the device has been running for a long time without reconnecting or was in the area of a bad signal, connection errors may have accumulated, and the presence of many stored profiles in the memory of the smartphone, which AirDots 2 previously paired with, also affects the presence of many stored profiles in the memory of the smartphone.
💡
If the sound is quieter or there is a crack, try first cleaning the speaker mesh with a soft dry toothbrush - often the problem is precisely the contamination, not the software failure.
And don't forget the trivial battery discharge, because when the battery is low, the power controller can be unstable, causing spontaneous shutdowns, and before you start complex manipulations, make sure that the case and the headphones are at least 30-40% charged.
- 📉 Stereochannels (left and right work separately).
- 📶 Accumulation of errors in the Bluetooth connection or interference from the Wi-Fi router.
- 🔋 Critically low battery charge or contact oxidation in case.
- 📱 Conflict of connection profiles in the memory of the smartphone.
Differences between reset and full reset
Many users confuse the concepts of “turn off”, “reset” and “reset.” In the context of Xiaomi TWS headphones, these actions have fundamentally different consequences for the device. The usual shutdown happens automatically when you put the headphones in the case, and they go into standby or charging mode.
Rebooting (or restarting) involves a short-term power outage followed by a no-deal switch, similar to restarting a computer: all temporary files are cleared, processes are restarted, but Bluetooth pair settings are saved, the first step in any malfunction.
⚠️ Warning: The Hard Reset completely erases the history of pairings. After this procedure, you will have to re-search the headphones in your phone's Bluetooth menu and create a new pair.
Resetting to factory settings is a radical measure, and it brings the headphone firmware back to where it was when it was purchased, and it's necessary if a normal reboot didn't work, or if you're planning to sell it to another person, and you do it through a special combination of touches.
💡
Use a regular reset (placed in a case) to solve small glitches, and a full reset (Hard Reset) – only if the headphones stopped seeing each other or the phone.
How to perform a normal reset (Soft Reset)
The easiest way to refresh your device is to force it to reboot through the charging case, which is safe and doesn't require you to delete profiles from your phone's memory, and it helps 80 percent of the time when you have a latency or an unstable connection.
First, remove both headphones from the case. If they're on or blinking, put them back down. Make sure the magnets are tightly pulling the devices in, and the charging lights are on. If the lights aren't on, wipe the contacts with dry cloth -- possibly dust is interfering.
Close the case cover (if you have one in your version) or just leave the headphones inside for 10-15 seconds. Then remove them again, at which point automatic synchronization between the left and right ears should occur, as signaled by the rapid flashing of indicators.
☑️ The soft reboot algorithm
If the lights flash in turn or turn on different colors after extraction, they're not synchronized. Try putting them back in the case again, but this time hold them there for 30-60 seconds. Sometimes the power controller takes longer to completely zero the state.
Instructions for complete reset (Hard Reset)
If the soft reboot fails, you need to reset completely, which causes AirDots 2 to forget all previous connections and re-start the search mode, especially if the headphones are seen by the phone as "R-BT" and "L-BT" separately.
The first step is to remove the device from the Bluetooth list on your smartphone. Find the listing of "Mi True Wireless EBs Basic 2" or "AirDots 2", click on the gear icon or "i" and select "Forget the device" or "Cancel pairing." This is a critical step without which the reset may not work.
Sequence of actions for discharge:
1. Place both headphones in the case.
2. Remove them at the same time.
3. Quickly press 5 times on the touch panels of both headphones.
4. Wait for 5 quick flashes of the indicator.An alternative method that often works more consistently on the second version is to hold the sensor. After extracting from the case, press and hold the touchpads on both headphones simultaneously for 20 seconds. The indicators should blink several times, then go out and light up again in red, signaling entry into reset mode.
What to do if 5 clicks do not work?
Once the procedure is successful, the indicators should start flashing white frequently, which means entering pairing mode, and you can reopen the Bluetooth settings on your phone and search for new devices.
Solving problems with synchronization of the left and right channel
The situation when only one headphone is working is the most common complaint of owners of Xiaomi AirDots 2. This is usually because the communication between the ears themselves, not between the headphones and the phone, is broken.
To restore stereo, you have to get the headphones to find each other before you connect to the phone. Put both earphones in the case, close it and wait a minute. Then pull them out, but don't plug them into the smartphone yet. 10-15 Stand next to each other on the table.
| Status of the indicator | Meaning | Action. |
|---|---|---|
| Blinks white (one) | Search mode (one earpiece) | Perform a full reset |
| Blinks white (both) | Phone interface mode | Connect to Bluetooth |
| Burning red. | Charging's coming. | Leave it in the case. |
| It's not burning. | Discharged or off | Check the contacts |
If one of the headphones flashes and the other doesn't, it means that the mono mode is activated by accident. Try turning off Bluetooth on your phone, put the headphones in your case, and then repeat the extraction procedure. It's important that both indicators behave the same way.
In some cases, re-pairing helps. After resetting, just plug in one earpiece (usually the one that flashes faster), play the music, then put it in the case. After that, pull out the second earpiece and plug it in as well. Then pull out both at the same time.
Diagnostics of hardware faults
It's not always the software that's the problem. If none of the reset methods work, you should pay attention to the physical condition of the device. Often, the contact pads on the headphones themselves or inside the case are oxidized, so the device doesn't see that it's been put on charge, and it doesn't turn off.
Take a cotton swab, moisten it lightly with alcohol (not abundantly!), and gently wipe the golden contacts on the bottom end of the headphones and pins deep in the case. Let the alcohol dry completely for 2-3 minutes before use. This restores normal charging current.
⚠️ Warning: Never use metal objects (needles, paper clips) to clean the contacts, this can short-circuit and cause the power controller to fail permanently.
Also check if the touchpad sticks. Dirt or fat can create a constant pressing effect, which causes the earphone to not respond to your commands or constantly reset the connection.
