Xiaomi Buds 3 Pro β flagship TWS-headphones (ANC), But many users have trouble getting this feature on the first time. ANC, plus transparency, which is often confused with turning off noise cancellation, in this article we will discuss all the official and hidden ways of activation, and also explain why sometimes you can use the technology to do it. ANC It doesnβt work even after the right settings.
It's important to understand that noise cancellation in Buds 3 Pro is not just dependent on the headphone firmware, but also on the Mi Fit/Xiaomi Wear app version, as well as the smartphone model. For example, on iPhone, ANC algorithms may work differently than on Xiaomi 13 Pro β this is something few people warn about. We tested all scenarios and collected current data for 2026 (including the latest V1.7.0.12 firmware for headphones).
1.The main ways to include ANC on Xiaomi Buds 3 Pro
There are three official methods of activating noise cancellation, but their effectiveness depends on the current state of the headphones. If you just unpacked a Buds 3 Pro, first perform the binding to the smartphone via Bluetooth β without this, the ANC cannot be turned on.
The most reliable way is through a proprietary app, but many users mistakenly believe that it is enough to click on the earphone touchpad, which works, but only if the function has already been activated in the software, and here are the step-by-step instructions for each method:
- π± Through the Mi app Fit/Xiaomi Wear: Suitable for Android and iOS, allows you to fine-tune levels ANC.
Letβs look at each method in detail, taking into account the nuances for different operating systems.
2. enable ANC via Mi Fit/Xiaomi Wear app
This is a priority method, because it allows you not only to turn on noise cancellation, but also to adjust its intensity. Importantly, the iPhone uses the Xiaomi Wear app, and on Android β Mi Fit (or Xiaomi Wear for new models), the interface in both cases is almost identical.
Step-by-step:
- Install the app from the official store (App Store or Google Play).
- Connect the headphones to your smartphone via Bluetooth (they should be defined as Mi True Wireless Earphones 3 Pro).
- Open the app and select Devices β Xiaomi Buds 3 Pro.
- Go to Noise Reduction Settings (or ANC in English).
- Activate Adaptive Noise Reduction Slider or select one of three levels (Weak, Medium, Strong).
Note that the latest firmware versions have introduced a "Smart ANC" mode that automatically adjusts the intensity based on ambient noise, and you can turn it on in the same menu.

If there is no partition with the ANC in the app, it means:
- π Headphones are dead (ANC shuts down when the charge is below 15%).
- π² Installed outdated firmware version (update via Settings) β Update of the PO).
- π΅ Headphones are not tied to Xiaomi account (authentication is required in the application).

If the ANC is gone after the firmware update, try removing the headphones from the Bluetooth device list, then reconnecting them through the app. This resets the settings cache.
3. Control ANC through touch panels of headphones
Xiaomi Buds 3 Pro headphones support gesture control, but the default ANC is a long touch (holding your finger on the touch panel), which is convenient when you need to quickly switch between modes, but only works if the function is already activated in the application.
Algorithm of action:
- Put on your headphones and make sure they are connected to the phone.
- Touch and hold the touchpad on any of the headphones for 2 seconds.
- You will hear a voice signal (in Chinese or English, depending on the region) and then the ANC will turn on.
- Long-touch re-cycling switches modes: ANC β Transparency β Off.
An important caveat: If you've never set up an ANC in the app, touch control won't work. Also check if the gestures in the settings are disabled:

4. Resetting and Forced Activation of ANC
If noise cancellation is not enabled either through the app or through gestures, there may have been a software failure, in which case a full reset of the headphones to the factory settings will help. This method is also useful if you bought a Buds 3 Pro used and the previous owner disabled the ANC.
Resetting instructions:
- Place both headphones in the case and close the lid.
- Open the lid and hold the button on the back of the case for 10 seconds until the indicator starts flashing red.
- Close the lid, then open it again and connect the headphones to the phone as a new device.
- After resetting, reconfigure the ANC through the Mi Fit app.
After resetting, all user settings (including equalizer and gestures) are reset. If the ANC still doesn't work, check:
- ποΈ The headphone firmware version (should not be lower) V1.4.0.8 steady-work ANC).
- π± Smartphone model: Some devices (e.g. Huawei with HarmonyOS) may have work restrictions ANC.
- π Condition of microphones: ANC Using external microphones to analyze noise β if they are contaminated, efficiency drops.

Resetting your headphones is a last resort, and before you do that, try reconnecting them to another smartphone to rule out a problem with your device.
5. Comparison of ANC regimes and transparency
Many users confuse active noise cancellation (ANC) and transparency mode, the first one extinguishes external sounds, and the second one, on the contrary, lets them through, amplifying voices and important signals (for example, ads in the subway). Buds 3 Pro implements three levels of ANC and one level of transparency.
| Regime. | Noise suppression level | Battery consumption | Recommendations for use |
|---|---|---|---|
| ANC Off. | 0% | Minimum | Quiet rooms, listening to music without interference |
| ANC Weak | ~30% | +10% to flow | Office, library (suppresses keyboards, whispers) |
| ANC Average | ~60% | +15% to flow | Street, transport (average noise level) |
| ANC Strong | ~85% | +25% to flow | Planes, construction, concerts |
| Transparency | -20% (intensifies external sounds) | +5% to flow | Conversations, Orientation in Space |
Important: Smart ANC (if available) automatically selects the level depending on the environment, for example, in the subway it activates Strong ANC, and in a quiet room it turns off noise cancellation completely, which saves charge, but can work unstable in noisy places with sharp changes in sound (for example, on a construction site).
Tip: If you need to switch quickly between ANC and transparency, set a triple-touch mode change:

Even after you set it right, the noise reduction sometimes fails.-5 causes and ways of eliminating them:
- Outdated firmware: ANC only appeared in V1.3.0.5. Update your headphones through the app.
- Conflict with other Bluetooth devices: Disable other gadgets (fitness bracelets, speakers) that may interfere with communications.
- Ear fit: ANC requires a tight fit. Try changing the size of the earpieces (the package includes S/M/L).
- iOS restrictions: On iPhone, some ANC features may be blocked due to Apple's policy.Use Android for initial setup.
- Hardware malfunction: If the ANC is not working after all the manipulations, check the microphones for physical damage (for example, after a fall).
Special attention is paid to firmware. V1.5.0.7 had a bug that caused the ANC to spontaneously shut down after 10 minutes, and if you have this version, upgrade to V1.7.0.12 or higher.

To check the current firmware version, go to Mi Fit β Xiaomi Buds 3 Pro β About the device. If the update is not available, try connecting the headphones to another Android 10+ smartphone β sometimes the Xiaomi server offers updates selectively.
β οΈ Note: If you bought Buds 3 Pro in China (domestic version), ANC It can be blocked for regions outside Asia, and only flashing through the engineering menu will help, but it does not guarantee that you will be able to do so.
7. Optimizing the ANC: Advice from Experts
Noise reduction in Xiaomi Buds 3 Pro works more effectively if you follow a few rules:
- π Charge above 30%: At low battery level ANC Automatically reduces intensity to extend work time.
- π΅ Quality Sound Sources: Use Music in a Format AAC or aptX -- compressed MP3 with a bitrate below 192 kbit / s, it worsens the work ANC.
- π§Ό Clean headphones: Once a week, clean the microphones (located on the outside of the case) with a cotton swab soaked in alcohol.
- π΅ Minimize interference: In the subway or plane, turn off Wi-Fi on your smartphone β it can interfere with Bluetooth.
For maximum effect, combine ANC with passive soundproofing. For example, on an airplane, use a strong ANC + earplugs under your headphones, which will reduce the load on the microphones and prolong the running time.
Another life hack: if you need to focus on work, turn on ANC Medium + pink noise playback (available in applications like Noisli), which creates a "silence zone" even in an open office.
