Xiaomi Mi True Wireless Earphones 2 Pro: How to Enable Active Noise Reduction (ANC)

Why is the ANC in Xiaomi Mi True Wireless Earphones 2 Pro not working out of the box?

Xiaomi Mi True Wireless Earphones 2 Pro headphones are equipped with a hybrid active noise reduction system (ANC), But many users find that the function doesn't activate automatically after the first connection, and the reason is because of the firmware architecture: the manufacturer disables it. ANC default to save battery power and prevent accidental switching on inappropriate conditions (such as when talking). ANC It may be blocked before the firmware update.

The second is the Mi Earphones app dependency, which only allows users to access basic functions without it, and the advanced settings (including noise reduction adjustment) remain hidden. This is typical of Xiaomi devices, where branded software plays a key role in unlocking the full potential of the gadget. For example, Redmi AirDots 3 Pro headphones have a similar scheme: without the ANC application, it runs at a minimum level, and with it opens 3 stages of adjustment.

Finally, hardware restrictions should not be ruled out: If you purchased headphones in the secondary market or through informal channels, there is a risk of running into a fake where the ANC is either physically absent or simulated software. Official Xiaomi dealers recommend checking the serial number through the service mi.com/verify in such cases.

Preparation before activating ANC: what to check?

Before you activate noise cancellation, make sure your headphones meet the minimum requirements:

• 🔋 Battery charge not lower than 30%. ANC consumes additional energy, and at a low charge level, the system can automatically turn off the function.
• 📱 The firmware version, for stable operation. ANC Firmware required at least 1.7.0.3 (checked in Mi Earphones app).
• 🎧 The right fit in the ears. ANC It's only effective when it's tightly fitted. Try changing the dimensional tips (the kit comes with it). S/M/L).
• 🔗 Connect to a smartphone: Headphones must be paired with the device via Bluetooth 5.0 or later (older versions of the protocol may not support the device). ANC).

Pay special attention to regional restrictions. In some countries (for example, in India), Xiaomi supplies headphones with stripped-down firmware, where the ANC is turned off at the firmware level. In this case, only flashing through the Mi Flash Tool will help, but this will void the warranty. Alternatively, use headphones with devices based on MIUI (for example, Xiaomi 13 Pro), where the ANC can activate automatically.

Step-by-step: how to enable ANC through the Mi Earphones app

The official way to activate noise reduction is through a proprietary app.

1. Install the Mi Earphones app from Google Play or the App Store. For MIUI devices, the app can be pre-installed called Mi Headphones.
2. Connect your headphones to your smartphone via Bluetooth. From the list of available devices, select Mi True Wireless Earphones 2 Pro.
3. Open the Mi Earphones app. On the home screen, tap your headphone icon.
4. Go to the Noise Reduction tab (or ANC in English). Slider Active Noise Reduction Move to the right.
5. Choose the intensity level: Weak, Medium or Strong. For the test, we recommend starting with medium.

Important! In some versions of the app, the ANC option is hidden behind an extra menu. If you don't see the slider, upgrade the Mi Earphones to the latest version or reinstall it. Also check that the headphones are connected just like the Mi True Wireless Earphones 2 Pro, not like a regular Bluetooth headset.

Alternative ways to enable ANC (without an app)

If the Mi Earphones app is not available (for example, on iPhones or devices without Google Play), you can try activating ANC via touch control or voice commands:

Method 1: Touch gestures

By default, Mi True Wireless Earphones 2 Pro uses touch control:

1. Touch and hold the right earpiece for 2 seconds.
2. You will hear a voice confirmation: “Noise Canceling On” (English: “ANC On”).
3. Re-holding will disable the ANC.

If the gesture doesn’t work, reset your headphone settings: press both touch panels for 10 seconds before the red light flashes.

Method 2: Voice assistant (only for the purpose of MIUI)

On smartphones. Xiaomi/Redmi/Poco s MIUI 12+ You can use voice commands:

1. Activate Xiaomi Voice Assistant (long press on the Home button).
2. Say, "Put the noise reduction on the headphones."
3. The system automatically forwards the command to Mi Earphones (if the application is installed).

Critical: on iPhones and Android without MIUI, voice commands for ANC do not work due to the limitations of the Bluetooth API, in which case only manual control through touch panels or installation of Mi Earphones via APK (for Android) remains.

Table: ANC Level Comparison in Mi True Wireless Earphones 2 Pro

The manufacturer offers 3 noise reduction modes, which differ in efficiency and impact on sound.

The optimal mode depends on the environment, for example, in an airplane, a strong ANC can cause dizziness due to a sharp drop in pressure, so it is better to use a medium one. In the office, it is weak enough to cut off the keyboard and conversations of colleagues, but not lose the quality of music.

💡

If you hear a hissing background when you turn on ANC, try reconnecting the headphones to your smartphone or changing the Bluetooth codec to AAC (in the Android developer settings).

Common problems with ANC and their solutions

Even when activated correctly, ANC may not work properly, and consider typical scenarios and ways to eliminate them:

• 🔊 Noise cancellation is on but not working: Check if the microphones on the headphones are blocked (they are located on the outside of the case). Wipe them with a dry wipe. If the problem persists, update the firmware through Mi Earphones.
• 🔋 ANC It discharges your headphones quickly: It's normal behavior -- active noise cancellation increases your power consumption by 10 to 15 percent. To extend your running time, use Weak or turn off mode. ANC quietly.
• 🎵 Sound distortion when on ANC: Try changing the Bluetooth codec to SBC (less resource-intensive. Go to Settings for this. → System system → Developer → Bluetooth codec.
• 📵 ANC Disable spontaneously: Most likely, overheating or low charge protection is triggered. Charge your headphones to 50% and try again. If the problem recurs, reset settings (press both touchpads for 10 seconds).

⚠️ Note: If after the firmware update ANC If you have stopped working at all, go back to the previous version via the Mi Flash Tool. In rare cases, new firmware contains bugs that block noise cancellation (for example, version 1.9.2.4 had a similar problem).

💡

The hybrid ANC in the Mi True Wireless Earphones 2 Pro combines two types of microphones: external (catch ambient noise) and internal (analyze sound in the ear canal), which allows you to more accurately suppress noise, but requires more energy.
