How to turn on noise cancellation on Xiaomi AirDots 3 Pro: a complete guide with secrets

Xiaomi AirDots 3 Pro wireless headphones have become one of the most popular accessories of the brand due to the combination of high-quality sound, convenience and active noise reduction (ANC). However, many users face difficulties when first turning on this feature - some do not find the right settings in the application, and others simply do not know that noise reduction needs to be activated manually. In this article, we will analyze all the ways to turn on ANC, the nuances of settings and typical errors that prevent the function from working correctly.

It’s important to understand that AirDots 3 Pro supports two noise reduction modes: Active (ANC) to block external sounds and transparent mode to amplify ambient noise (useful on the street or in transport). You can switch between them both through the branded Mi Home app and using touch buttons on the headphones themselves. But there’s one caveat: if you’ve never set up your headphones through the app, some of the features may not be available. Next, detailed instructions for all cases.

1. Preparation of headphones for noise reduction setting

Before you turn on the ANC, make sure your Xiaomi AirDots 3 Pro is ready to go.

• 🔋 Charging headphones and case: the charge level should be at least 30%. At low charge, noise cancellation may work unstable or turn off.
• 📱 Phone pairing: Headphones must be connected to the smartphone via Bluetooth (instructions below if not connected).
• 📲 Install the Mi Home app: without it, only basic features are available. Download the latest version from Google Play or the App Store.
• 🔄 Firmware update: outdated firmware can block work ANC. Check the relevance in Mi Home.

If the headphones are not connected to the phone, do it manually:

1. Open the case cover and remove the headphones - they will automatically go into pairing mode.
2. On your smartphone, turn on Bluetooth and select Mi True Wireless Earphones 3 Pro from the list of available devices.
3. Confirm the connection if requested. PIN-code, enter 0000.

Attention, if the headphones were previously paired with another device, reset their settings.

1. Put both earbuds in the case.
2. Press and hold the touch button on the right earphone for 10 seconds until the indicator starts flashing red and white.
3. After resetting, reconnect the headphones.

2. Enable noise reduction through the Mi Home app

The most reliable way to activate the ANC is to use the official application.

1. Open Mi Home and make sure the headphones are connected to the phone.
2. In the main menu, find Mi True Wireless Earphones 3 Pro (if the device doesn’t appear, click Add Device → Headphones).
3. Go to the headphone settings (cog icon in the upper right corner).
4. Select the Noise Reduction (ANC) section.
5. Activate Active Noise Cancelation, where you can adjust the intensity (usually 3 levels: weak, medium, strong).

Additional options are available in the same menu:

• 🔄 Transparent mode - amplification of external sounds.
• 🎧 Setting up touch buttons - appointment ANC double/triple touch.
• ⚡ Energy saving - shutdown ANC low charge (recommended to be left on).

Important: If the app does not have a Noise Reduction section, update the headphone firmware. To do this, in the Mi Home settings, find the "Software Update" and follow the instructions.

3. Controlling noise cancellation with touch buttons

If you don't want to open the app every time, you can switch modes right on your headphones. By default, Xiaomi AirDots 3 Pro supports the following gestures:

To reassign the buttons:

1. Open Mi Home → headphone settings.
2. Select Touch Control.
3. Assign the desired action (for example, double touching the right earphone → Noise suppression).
4. Save the settings.

💡

If the touch buttons don’t respond, wipe your headphones with a dry wipe – dirt or sweat can block the sensors.

4.ANC health check: how to know if noise cancellation is working

Many users turn on the ANC, but don't feel the difference. Here's how to check if the feature is active:

• 🎵 Music Test: Turn on a track with a clear bass sound (e.g. electronic music). ANC must "smooth out" low frequencies of external noise (e.g. air conditioning hum or street noise).
• 🚗 Test in transport: in the subway or bus turn on ANC — The sound of the engine and the conversations should be quiet.
• 🔊 Voice test: Ask someone to talk next to you. ANC The voice will be muted, in a transparent mode - reinforced.
• 📱 Indication in the application: in Mi Home next to the slider ANC The green checkmark should burn.

If there is no difference, check:

• 🔇 Volume level on headphones (ANC better heard 50-70% volume).
• 🔄 The correctness of wearing headphones (they should fit tightly to the ears).
• 📵 Interference from other Bluetooth devices (disable them).

Typical problems and their solutions

Even after setting up properly, the ANC can malfunction.

⚠️ Attention! If the noise reduction is gone after the firmware update, try rolling back the software version. To do this, look for the Software Update section in Mi Home and select Return to the previous version (if the option is available).

If none of the solutions worked, try resetting the headphones to factory:

1. Put both earbuds in the case.
2. Hold the button on the case for 15 seconds until the indicator flashes red.
3. Reconnect the headphones and set up the ANC.

6.Comparison of AirDots 3 Pro noise reduction with competitors

The ANC in Xiaomi AirDots 3 Pro is a mid-range one, which effectively mutes low-frequency noise (engines, air conditioners), but is worse at handling high frequencies (voices, baby crying).

• 📈 Huawei FreeBuds 4i: ANC harder 20-30%, But headphones are less comfortable for long-term wear.
• 📉 Redmi AirDots 3: No active noise cancellation, only passive soundproofing.
• 💰 Sony WF-1000XM4: best ANC on the market, but the price in 3-4 higher.
• ⚡ Realme Buds Air 3: Comparable quality ANC, But worse than autonomy.

The advantages of ANC in AirDots 3 Pro:

• 🔋 Low energy consumption (ANC reduce the time of work on 1-1.5 hourly 7 before 5.5 hours).
• 🎛 Flexible intensity setting (3 levels).
• 💻 Compatibility with PC and Mac (ANC It also works when connected to a computer).

💡

Noise reduction in AirDots 3 Pro is optimal for office, transport and home use, but will not replace top models for air travel or noisy production facilities.

7.How to prolong the life of headphones with active use of ANC

The ANC is increasing the battery and headphone microphone loads to make the AirDots 3 Pro last longer.

• 🔌 Charge correctly: Use the original cable and avoid overheating (do not leave in the sun or near heat sources).
• 🧼 Clean your headphones: once a week wipe the earbuds with an alcohol napkin and remove earwax from the microphone grilles.
• 🔇 Turn it off. ANC When simple: if you do not use noise reduction, switch to standard mode.
• 📦 Store in a case: This protects against dust and mechanical damage.

The average lifespan of the AirDots 3 Pro with regular use of ANC is 1.5-2 years. If noise reduction began to work worse (hissing appeared, the effect disappeared), this may indicate:

• The microphones are worn (replacement is required).
• Pollution of microphone grids.
• Battery discharge (capacity drops after 300-400 charging cycles)

⚠️ Attention, don't use headphones with ANC At maximum volume in noisy places (e.g. concerts) this can lead to acoustic injury — noise cancellation blocks external sounds, and you unconsciously increase the volume to compensate for this.
