Xiaomi Air 2 Pro wireless headphones have become one of the most popular gadgets of the brand thanks to the combination of high-quality sound, convenient ergonomics and advanced active noise reduction (ANC). However, many users face difficulties when first turning on this feature – especially if they have not previously dealt with premium headphones. In this article, we will discuss all possible ways to activate the ANC, including hidden settings, as well as how to properly test the effectiveness of noise reduction and fix typical problems.
It’s important to understand that the Xiaomi Air 2 Pro supports two noise reduction modes: Active (ANC) to block external sounds and transparent mode to amplify ambient noise. Switching between them can be done through the Mi Home/Xiaomi Wear app, and using physical buttons on the headphone case. But there are nuances: for example, some features become available only after updating the firmware. We will discuss each method in detail so you can choose the most convenient one.
1. Ways to enable noise reduction on Xiaomi Air 2 Pro
Headphones Xiaomi Air 2 Pro offer three main ways to control ANC: through the mobile application, button combinations and voice commands (when paired with Xiaomi AI Assistant).
The most reliable method is to use the official Xiaomi Wear app (formerly Mi Home), which not only allows you to turn on/off noise cancellation, but also adjust its intensity, as well as update the firmware of the headphones. However, if the application is not available for some reason (for example, on iOS), you can do without it – using mechanical buttons.
- 📱 Through the application: the most flexible way with the ability to fine-tune.
- 🔘 Through buttons: fast switching without a smartphone (works even if the headphones are not connected to the phone).
- 🎧 Automatically: Some firmware supports activation ANC headphone-wearing.
2. Step-by-step: Enabling ANC through the Xiaomi Wear app
The official Xiaomi Wear app (available for Android and iOS) gives you full control over the Air 2 Pro settings, including noise cancellation.
- Install the Xiaomi Wear app from Google Play or the App Store.
- Connect your headphones to your smartphone via Bluetooth (they should be defined as Mi True Wireless Earphones 2 Pro).
- Open the app and select your headphones from the list of devices. If they don't show up, click Add Device → Headphones → Xiaomi Air 2 Pro.
- Go to Noise Reduction Settings (or ANC Settings in English).
- Activate the Active Noise Canceling (ANC) switch, and you can select the intensity level (weak, medium, strong options are usually available).
Note: Some versions of the headphone firmware may call the ANC section Sound Modes or Effects. If you don't see the noise reduction option, update the headphone firmware through the same app (Update section).
☑️ Preparation for setup ANC via
Noise reduction control without application (via buttons)
If you don’t have access to the Xiaomi Wear app (like on devices without Google Play Services support), you can turn on the ANC using physical buttons on your headphones.This method works on all firmware but provides fewer options to customize.
Algorithm of action:
- Put on your headphones and make sure they are on (the indicator should flash white or burn blue).
- Press and hold the touchpad on the right earphone for 2 seconds until you hear the beep.
- After the signal release the panel - the headphones will switch to ANC mode. Re-hold switch to transparent mode, and the third - turn off noise cancellation.
Important: Some firmware requires triple tapping (not retention) to activate the ANC. If double taping involves voice assistant, update the headphone firmware.
| Action. | The result | Sound signal |
|---|---|---|
| Hold 2 seconds (right panel) | Inclusion of ANC | Double high signal |
| Hold 2 seconds (right panel) | Transparent mode | Double low signal |
| Hold 2 seconds (right panel) | Shutting down the ANC | Single signal |
| Double touch (left panel) | Voice assistant | Connection sound |
⚠️ Warning: If the headphones don't respond to touch, check if the Game mode (low latency) is activated. In this mode, the touchpads can be turned off to prevent accidental taps.
4.Noise reduction check: how to make sure the ANC is working
Many users include ANC but are not sure if it actually works. Here are a few ways to test the noise reduction efficiency on the Xiaomi Air 2 Pro:
- 🔊 Low frequency noise test: Turn on ANC And you can put your headphones up to a dryer or air conditioner that's working, and effective noise reduction should reduce the volume of the hum significantly.
- 🎵 Music Test: Turn on a track with minimal sound (e.g. classical music without percussion) and compare the level of external noise with the one off and on ANC.
- 🗣️ Voice test: Ask someone to speak next to you. ANC The voice should sound muffled, and in transparent mode - amplify.
If noise reduction is not working well, try:
- Change the ANC intensity level in the app (select Strong over Medium).
- Check the density of the adhesive of the earpieces - they should completely close the ear canal.
- Update the firmware headphones (in the application Xiaomi Wear).
💡
For maximum efficiency, use the right sized ANC earpieces. The Air 2 Pro comes with 3 pairs (S/M/L) to pick the ones that fit tighter to the ears.
5. Common problems with ANCs and their solutions
Even when switched on correctly, noise cancellation may not work properly, and here are the typical faults and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| ANC does not turn on via buttons | Outdated firmware | Update the software through Xiaomi Wear |
| Noise suppression weak | The loose fit of the ambushures | Replace the slacks with a larger/smaller size |
| Extraneous sounds (hisping, crackling) | Bluetooth interference | Reconnect your headphones, avoid interference sources |
| ANC spontaneously shuts down | Low battery charge | Charge your headphones to 50% or more |
If none of the methods helped, reset the headphone settings:
- Put the headphones in the case.
- Hold the button on the case for 10 seconds until the indicator starts flashing red.
- Take out the headphones and reconnect them.
⚠️ Warning: Resetting will return the headphones to factory settings, including settings ANC. After the procedure, a re-update of the firmware may be required.
What happens if the ANC stops working?
6. Comparison of noise reduction modes: ANC vs Transparent mode vs Off
Headphones Xiaomi Air 2 Pro offer three main modes of working with sound:
- 🔇 ANC (Active noise cancellation: Blocks outdoor noise, ideal for traveling or working in noisy places.
- 👂 Transparent mode: Enhances surrounding sounds, is useful for conversations or orientation in space.
- 🎧 Turned off: Natural sound without processing, suitable for listening to music in a quiet environment.
Which regime to choose?
It depends on the situation.
- In transport/aircraft: ANC at maximum power.
- Outdoors: Transparent security (to hear cars)
- Home/office: ANC is medium or off.
💡
Transparent mode consumes more battery than ANC, because it requires constant sound processing from the microphones, and if you don't want increased audibility, you'd better turn it off.
7 How to extend the service life ANC-microphone
Active noise cancellation is based on miniature microphones that analyze external sounds to make them last longer.
- 🧼 Clean microphone holes regularly (use a soft brush or compressed air).
- 💧 Avoid moisture: Do not use headphones in the rain or in the bathroom (despite protection) IP54, Microphones are sensitive to condensation).
- 🔋 Don't discharge completely: ANC It requires a lot of energy, so keep an eye on the charge level (it is best to keep it above 20%).
- 📦 Store in a case: This protects microphones from dust and mechanical damage.
If you notice that the noise reduction quality has deteriorated (there is hissing, ANC has become less efficient), this may indicate a clogging of the microphones. In most cases, the problem is solved by cleaning, but if the sound has not recovered, contact the service.
