Modern wireless headphones, such as the popular Redmi AirDots, often encounter software errors during operation. Users may notice channel desynchronization when sound is played in only one ear, or problems with connecting to a smartphone. In such situations, standard Bluetooth reconnection rarely helps, and more radical intervention is required in the operation of the device.
Completely resetting the settings to factory settings allows you to clear the internal memory of the headset from accumulated errors and return it to its original state. This procedure is necessary if you are faced with permanent connection breaks or if the headphones no longer see each other. Properly performing all the steps ensures that the accessory is restored to work without contacting the service center.
Before you start taking action, it’s important to understand that the process requires accuracy and consistency. An incorrect press sequence can cause the device to remain in pairing mode but not perform configuration cleanup. Xiaomi has developed several firmware variations, so the algorithm of actions can vary slightly depending on the specific model and year of release.
Preparation of headphones and smartphone for the procedure
The first and most critical step is to get the equipment properly prepared. Make sure that there is enough power left in the Redmi AirDots charging case, as the devices must not turn off during the reset. If the charge is critically low, set the case on charging for at least 15-20 minutes, but it is better to remove the headphones from it before you start manipulating.
On the smartphone side, you need to perform a series of preparatory steps in the Bluetooth menu. Go to the wireless settings of your Android or iOS device. Find your headphones (they may be called Redmi AirDots, Mi True Wireless EBs or just AirDots) in the list of previously connected devices and select the option “Forget device” or “Unpair”.
After removing the connection profile, it is recommended to turn off Bluetooth completely on the phone, which will prevent attempts to automatically reconnect (reconnect) during the process when the headphones are in setup mode, and it is also worth closing all applications that can use audio output, such as music players or voice messaging messengers.
⚠️ Warning: Do not leave your headphones in the case while reseting. They should be outside the charging case so that the touch panels are accessible for touch and LED indicators are visible for status control.
☑️ Preparation for discharge
Full reset algorithm for different modifications
Hard reset may vary depending on the firmware version and model. Most Redmi AirDots 1 and 2 have long-term touch-zone retention. Remove both earbuds from the case and wait for them to catch fire. If they flash red and white, they're in pairing mode, if they only burn red, they're off.
To do the reset, you need to simultaneously touch the touchpads of both headphones and hold your finger for about 5-7 seconds. You will hear a voice message "Power off" but do not let go of your fingers. Continue to hold the sensors for another 15-20 seconds. At this point, the headphones should flash red several times, signaling the beginning of the memory cleanup process.
There is an alternative method for some revisions, where you need to turn off the headphones (hold 5 seconds before turning off), and then again pinch the sensors for 20 seconds until they flash red.
What to do if the voice message does not sound?
Correct re-channel synchronization
The most common mistake after reset is to try to connect the headphones to the phone right away, which causes the left and right channels to be out of sync, and the device works like a mono headset, and you first need to reconnect the earbuds themselves.
Put both headphones back in the charge case and close the lid (if any) or just tightly insert them into the contacts. Wait 5-10 seconds, then remove both headphones at the same time. They should automatically turn on and start flashing quickly in white, which means finding each other.
When the channels find each other, one of the indicators (usually the right earbud) should go out or start flashing slowly (once every 2 seconds), while the second will continue to blink quickly.This is the key point, meaning that TWS (True Wireless Stereo) communication is restored and now the device is ready to search for a smartphone.
The process of pairing with a mobile device
Only when the headphones are in pairing standby mode (slow flashing of a white light on one of the ears) can Bluetooth be turned on on the phone. The list of available devices should appear the name Redmi AirDots (sometimes with the prefix R or L, which is normal until the connection).
Click on the device name to connect, and successful synchronization will be confirmed by the voice message "Connected" and the characteristic audible signal, and then both earbuds must work in stereo mode, distributing the channels correctly.
If two identical devices are displayed in the Bluetooth list (e.g. two Redmis) AirDots_R), It means that the synchronization between the ears has not gone away, so you have to "forget" both devices again in the phone settings, turn off Bluetooth, put the headphones in the case, and repeat the reset and primary synchronization procedure again.
| Indication | Status of device | User action |
|---|---|---|
| Fast blinking (white) | Search/pair mode | Search in Bluetooth smartphone |
| Slow blinking (white) | Waiting for connection | Confirm the connection |
| Burning red. | Charging's coming. | Leave it in the case. |
| Blinks red. | Low charge or error | Charge or reset |
Diagnosing problems after resetting
Even after a successful reset, some problems can persist that are often confused with software failure, such as a quiet sound in one of the headphones can be caused by contamination of the speaker's mesh with earwax or dust, in which case the acoustic membrane is blocked, and the program reset will not help - neat cleaning is required.
If you see a sound desynchronization (echo or delay), check the developer's settings on Android. The "Absolute Volume Level" option sometimes conflicts with Xiaomi protocols. Try to change its state (on or off) and restart the phone.
Also, consider that older versions of Bluetooth on a smartphone may not work properly with new codecs. Make sure the phone's operating system is updated. In rare cases, cleaning the Bluetooth service cache in Android app settings helps.
⚠️ Note: If after multiple resets headphones behave identically, the problem may lie in the hardware, for example, in the degradation of the battery of one of the modules, which does not allow it to keep in touch.
💡
Use a cotton swab slightly soaked in alcohol to clean the charging contacts on the headphones themselves. Oxidation of the contacts often causes one earphone to fail to charge or turn on, simulating a software failure.
Failure prevention and operational recommendations
To avoid the need for frequent resetting, you should adhere to simple rules of operation. Do not allow the full discharge of batteries "to zero" during long-term storage. TWS-Headsets are sensitive to deep discharge, which can lead to unstable operation of the controller.
Clean the chargers on the case and headphones regularly. Dirt and oxides create resistance, which may cause the headphone to not charge up to 100%, which is perceived by the system as a power error. Also try not to keep the case with headphones near powerful sources of electromagnetic radiation (routers, microwaves) during operation.
Periodically update your headphone firmware through the Mi Wear or Xiaomi Earbuds app if your model supports this feature. Updates often contain patches that improve connection stability and fix known bugs of previous versions of the software.
💡
Regular cleaning of charging contacts and avoiding deep battery discharge prolong the life of headphones and reduce the risk of software failures by 80%.
