Modern wireless headphones, such as the Xiaomi Mi AirDots Pro 2, offer functionality that was previously only available in premium audio devices. One of the key features of this headset is an active noise cancellation (ANC) system that allows you to enjoy music even in noisy urban environments or public transport. However, many users face difficulties in the initial setup, since the headphones themselves do not have a physical button to switch modes.
To control all functions, including turning on and off noise reduction, you need to use special software. Without connecting to the smartphore through the Mi True Wireless Earbuds Basic 2 or Xiaomi Earbuds app (depending on the region), the device operates in base mode without the possibility of fine-tuning. In this guide, we will detail the process of activating ANC, consider the available modes of operation and answer frequently asked questions.
The need to use a proprietary application
The main feature of the Xiaomi Mi AirDots Pro 2 is that there is no direct access to switching noise reduction modes through the touch panels on the headphones themselves. Touch zones are designed exclusively for controlling playback, voice assistant call and pairing. Therefore, installing a mobile application is a must for those who want to use the full potential of the device.
The software mediates between the user and the headphone microcontrollers, and it's through the application interface that commands the activation of the noise-cancellation algorithms, without this connection, the headphones operate in standard passive isolation mode, which depends only on the quality of fitting the earbuds.
💡
Make sure your Xiaomi Earbuds app is updated to the latest version via Google Play or the App Store, as older versions may not have some ANC modes.
The pairing process usually occurs automatically at the first connection, if the smartphone has the appropriate service framework MIUI. Otherwise, the system itself will offer to download the necessary plugin. The stability of the Bluetooth connection at this point is critical, since interruption of data transfer can lead to an error in installing the device profile.
Step-by-step instruction for activating noise reduction
After successfully connecting the headphones to the smartphone and opening the Xiaomi Earbuds app, the user is taken to the main control screen, which displays the charge of each headphone, the current mode of operation and connection status. To enable the function, you need to find the section responsible for noise management, which is usually indicated by the icon of the headphone with waves or the inscription “Noise Control”.
There are several options available inside the noise control menu: you need to select Active Noise Cancellation mode, and when you switch to this mode, the headphones start generating antiphase of external sounds, effectively suppressing low-frequency hum, and you can also choose the transparency mode if you need to hear the environment, or completely disable the processing of sound.
☑️ Verification of activation ANC
It's worth noting that it can take anywhere from one to three seconds to switch modes, at which point you may hear a characteristic beep or a voice notification in your headphones confirming the change of mode. If there's no reaction, check the status of the connection in the app - maybe communication with one of the channels has been lost.
Analysis of available microphone modes
The noise reduction system in the Mi AirDots Pro 2 is not a monolithic feature, it is a complex operation of several microphones and a sound processing processor. Understanding the differences between modes will help you choose the best option for a particular situation.
- 🎧 Active Noise Cancellation: Maximum noise reduction, perfect for subway, plane or noisy streets.
- 🔊 Transparency Mode: Transparency Mode that amplifies external sounds so you can hear ads or interlocutors without removing your headphones.
- 🔇 Off: Complete shutdown of electronic processing, only passive noise insulation works due to the construction of the housing.
Each mode consumes energy differently. Active noise cancellation is the most expensive battery life, because processors are constantly analyzing the sound environment. Transparency mode is also energy intensive, while Off mode allows you to significantly extend the battery life of the device.
Technical details of the ANC operation
Choosing the right mode affects not only comfort, but also the quality of voice transmission during calls. In noisy places, using transparency mode can lead to the interlocutor hearing background noise, whereas ANC helps isolate your voice.
Table of comparison of regime characteristics
To give you a better idea of how different settings work, we've developed a spreadsheet that will help you quickly navigate the functionality and understand which mode is best to use in a given situation.
| Parameter | ANC (Noise Canceling) | Transparency | Off. |
|---|---|---|---|
| Noise suppression | High (up to 30 dB) | Strengthening external sounds | Only passive. |
| Battery consumption | High-pitched | High-pitched | Low. |
| Quality of music | Clean, uninterrupted. | Mixed with environment | natural |
| Best application | Transportation, office | Walk, run. | Quiet room. |
As you can see from the table, Active Noise Cancellation provides the best insulation, but you have to pay for it with the speed of battery discharge. If you plan a long flight or trip, it makes sense to bring a charging case with you.
Using the “Switched Off” mode is advisable in quiet rooms where there is no need for additional insulation, which saves charge and reduces the load on the electronic components of the device, extending the overall life of the battery.
💡
The optimal balance between sound quality and autonomy is achieved when using ANC only in noisy environments, switching to Off mode in silence.
Advanced equalizer and sound settings
In addition to noise management, Xiaomi Earbuds provides access to equalizer settings, which can significantly affect music perception and noise reduction efficiency. In some cases, improper frequency settings can create the illusion of a bad ANC.
The audio effects menu includes presets like "Bass Boost," "Vocal" or "Treble Boost." Activating bass amplification can visually (by ear) compensate for low-frequency hums that are not completely suppressed by noise reduction. However, be careful: excessive amplification of low frequencies can lead to distortion of sound and rapid hearing fatigue.
Also in the settings, you can find the option "Wind Noise Reduction" -- a feature that's particularly useful when you use headphones outdoors during wind or when you're cycling fast -- and it uses algorithms to filter out the specific whistles that are generated by the air flow around the microphones.
Remember that all the changes in equaliser apply instantly. You can experiment with settings by listening to a familiar track to find the perfect mix for your hearing and genre preference. Sound personalization is a key step in customizing any audio device.
Possible problems and ways to solve them
Despite the high reliability of the technology, users may encounter situations where noise cancellation is not turned on or is not working correctly. One common reason is the loose fit of the earphone to the ear. If the tightness is impaired, the system cannot effectively analyze external noise and create antiphase.
⚠️ Attention: If you feel that ANC It's not working well, so try replacing silicone embroideries with bigger or smaller ones, and fitting them properly is critical to the noise reduction system.
Another cause may be contamination of microphone nets, and dust, earwax, or villi from clothing can block the holes through which sound is received for analysis, and regular cleaning of headphones with a soft dry cloth or a special brush will help avoid this problem.
In rare cases, you need to reset the headphones to the factory, you need to put both headphones in the case, open the lid and hold the function button on the back for 10-15 seconds before the indicator flashes, and then the pairing and setting of the ANC will have to be done again.
Impact of firmware on the functionality of the device
The manufacturer periodically releases software updates for Mi AirDots Pro 2. These updates may include noise reduction algorithm improvements, Bluetooth connection errors fixes, or new audio profiles. Ignoring updates may result in your device not working as efficiently as it could.
Check for updates is done directly in the application Xiaomi Earbuds. Usually when a new version is released on the home screen, the update process takes a few minutes and requires that the headphones are in the case and charged at least 30-40%.
⚠️ Warning: Do not open the case cover or remove the headphones during firmware updates. interruption of the process can lead to irreversible damage to the headphone software.
Newer firmware versions often optimize power consumption in ANC mode. If you notice that your headphones are running out faster than usual, checking and installing the latest version of the software may be the solution, and updates can improve connection stability in places with a lot of radio interference.
