In this article, we will discuss all the nuances of activation. ANC In AirDots Pro 2, we compare noise reduction modes in terms of efficiency, and give practical tips for optimizing sound, and we will focus on the typical errors that interfere with the correct operation of the function, and how to fix them. If you just purchased these headphones or have been using them for a long time, but could not deal with noise cancellation - this instruction is for you.

What is it? ANC Xiaomi AirDots Pro 2 and how it works

Active noise reduction technology (ANC — Active Noise Cancelling in Xiaomi AirDots Pro 2 is based on the principle of destructive interference of sound waves. Simply put, embedded microphones pick up external noises (such as traffic hums or office conversations), and then the headphones generate opposite sound waves that quell those noises, resulting in only pure sound from the source — music, podcast or voice of the interlocutor.

Unlike passive sound insulation (which depends on the density of the adjoining embushures), ANC It's a very active fight against low-frequency noise, which is what's most common in transport or airplanes:

🔊 Constant noises (train engine, air conditioning) are most effectively suppressed than sharp sounds (screams, clapping).
🔋 ANC Increases battery consumption by 10-15% compared to the off mode.
🎧 The quality of noise reduction depends on the proper fit of headphones in the ears – if the earbuds fit loosely, the effectiveness falls.

Xiaomi AirDots Pro 2 offers three modes of operation ANC:

ANC Actively suppressing external noise.
Transparent mode – skips surrounding sounds (useful for safety on the street).
ANC switched off – standard mode without noise processing.

📊 How often do you use noise reduction in your headphones?

Constantly.

Only in transport.

Rarely.

Never.

Step-by-step instruction: how to turn on ANC In AirDots Pro 2

Activate noise cancellation in Xiaomi AirDots Pro 2 You can do this in two ways: through touch control on the headphones themselves or using the Mi mobile app. Home/Xiaomi Wear, let's look at both.

Comparison of noise reduction modes: which to choose

Choice of regime ANC It depends on the situation you're using your headphones. Below is a comparison table with recommendations.

Regime.	Noise suppression level	Battery consumption	When to use
ANC on.	⭐⭐⭐⭐ (85–90%)	High-pitched (+15% to the expense)	In transport, aircraft, office with air conditioning
Transparent mode	⭐ (snooze)	Low (+5%)	Outside, running, in public places
ANC switched off	⭐⭐ (passive isolation)	Minimum	At home, in a quiet environment

In practice. ANC AirDots Pro 2 is best at handling low-frequency noise (up to 1 kHz), such as:

🚆 The hum of a train or subway.
✈️ Noise of aircraft engines.
🌬️ Operation of the air conditioner or fan.

But for high-frequency sounds (baby crying, machine signals), the efficiency is lower. ANC tight-planted.

Why? ANC do not suppress the voices of the people?

Active noise cancellation in budget headphones is optimized for constant low-frequency noise. Human speech contains a wide range of frequencies (from 80 Hz to 8 kHz), and completely suppress it without distorting the music is technically difficult. WH-1000XM5) It uses multiple microphones and adaptive algorithms, which AirDots Pro 2 doesn’t.

Typical problems with ANC And how to solve them.

Even when you turn on the noise reduction system correctly, it can be incorrect, and let's look at some of the most common problems and how to fix them.

1. ANC It is switched on, but no noise is suppressed.

If you do not notice a difference after activating the mode, check:

🔋 Battery charge: at a level below 20% ANC Automatically shut down to save energy.
🎧 Density of fitting: try changing the embushures to a larger / smaller size.
🔄 Firmware: Update your headphones through the Mi Home app.

2. there is a hissing or whistling in the headphones

This defect is related to the microphones. ANC. To eliminate him:

🧹 Clean the microphone holes on the headphone case (use a soft brush).
🔇 Reduce the volume of playback – sometimes the whistle is amplified at maximum volume.
🔄 Reboot the headphones: Put them in the case for 10 seconds, then pull out.

3. ANC spontaneously shut down

If the noise reduction is turned off without your involvement, the reasons may be as follows:

📱 Conflict with other Bluetooth devices: disable unnecessary gadgets in Bluetooth settings.
🔋 Critical Charge Level: Charge your headphones to 50% or higher.
📲 Firmware failure: perform a reset (clutch the touch panels on both headphones for 15 seconds).

💡

If the problem is ANC It is saved after all manipulations, check the headphones on another device (smartphone, tablet). If the defect is repeated, contact the service center: hardware failure of microphones is possible.

How to improve the quality of noise reduction: life hacks

Even with the limitations of AirDots Pro 2, you can achieve more efficient work. ANC, follow these advices:

Pick the right earbuds: Complete with headphones go 3 legging (S/M/L). Dense fit improves passive insulation and helps ANC. It's easy to check for tightness: put on earphones without music and cover your ears with your palms. If the sound of the outside is noticeably muffled, the earbuds are suitable.
Use uniform pressure: Don't insert the headphones too deeply - this can create discomfort and worsen the sound. Optimal position: the ear canal should be tightly wrapped around the ear canal, but not pressing it.
Update the firmware: Xiaomi regularly releases updates that improve algorithms ANC. To check the relevance of the software, go to the Mi Home application → Device profile → Update of the PO.
Experiment with the source of sound: Some music tracks (especially those with a plentiful bass sound) may be in conflict with the sound source. ANC, Try to turn on the mode on a quiet song or podcast.

Combine for maximum effect ANC externally:

🧢 In transport, wear a hood or scarf - this additionally muffles noise.
🎵 Use music with noise masks (e.g., white noise) or ASMR) boost.

💡

If you use it often ANC In the subway, create a playlist with a special folder with tracks where bass is not predominant, which will reduce the load on the microphones and prolong the running time.

ANC Transparent mode: when to use what

Many users mistakenly believe that transparent mode is just “off”. ANC". It's actually a separate feature that amplifies the surrounding sounds through the headphone microphones, and it's useful in situations where you need to stay informed about what's going on around you without taking your headphones off.

Criteria	ANC (Noise Canceling)	Transparent mode
Purpose	Insulate from external noise	Hearing the environment
Battery consumption	High-pitched	Medium.
Examples of use	Flying in an airplane, working in an office	Running down the street, riding a bike
Impact on sound	Can slightly mute high frequencies	Adds an "echo" to surrounding sounds

Fun fact: AirDots Pro 2 can use transparent mode as a sound amplifier for people with mild hearing impairments, for example, if you can't hear in a noisy room, turn on this mode to help you better understand the speaker's speech.

Can I use it at the same time? ANC and transparent?

No, these modes are mutually exclusive, but in some scenarios (e.g., in an airplane) you can switch between them quickly: ANC to suppress engine noise and transparent mode for communication with the flight attendant.
