Noise suppression in Xiaomi headphones: how to turn on and configure ANC rightly

Xiaomi headphones with active noise cancellation (ANC) They've become a popular choice among users who value silence in busy cities or transportation, but many owners have difficulty turning it on for the first time -- especially if they're models with a non-obvious control interface. ANC for different lines of Xiaomi headphones, from budget Redmi AirDots to flagship Xiaomi FlipBuds Pro, and also reveal the nuances of the settings that the manufacturer often does not keep silent.

It's important to understand that the noise reduction technology in Xiaomi headphones is implemented differently depending on the model. ANC It's a multi-mode version, and somewhere it's a simplified version with basic low-frequency suppression, and not only will we show you how to turn on noise cancellation, but we'll also explain why sometimes it can fail despite the right settings. If you have just unpacked new headphones or have not used them in a long time ANC — This guide will help you avoid typical errors.

What Xiaomi models support noise reduction (ANC)?

Not all Xiaomi headphones are equipped with active noise cancellation.To avoid wasting time looking for a non-existent feature, check if there is any. ANC Here's a list of the latest technology-enabled devices:

• 🎧 Xiaomi FlipBuds Pro – Hybrid ANC 3 modes (strong/medium/weak)
• 🎧 Xiaomi Buds 4 Pro – adaptive noise cancellation with pressure sensors
• 🎧 Redmi Buds 4 Pro — ANC level-adjusted
• 🎧 Xiaomi Buds 3 Pro – basic noise cancellation (without a hybrid scheme)
• 🎧 Redmi AirDots 3 Pro – Simplified ANC (low-frequency)

Note that Redmi AirDots 2, Xiaomi Mi True Wireless Earphones 2 and earlier models do not have active noise cancellation. There can only be passive sound insulation due to the design of the helmets "ANC" — It is probably a passive noise reduction (this is a marketing move, not a real function).

It is also important to note that even in supported models, quality is not ANC So, for example, FlipBuds Pro can handle the noise of an airplane or subway, and AirDots 3 Pro can only slightly mute the street hum.

Ways to enable noise reduction in headphones Xiaomi

Depending on the model, activate ANC There are three main ways:

1. Through touch control (touching the headphone body)
2. In mobile app (Mi Earphones or Xiaomi Wear)
3. Voice assistant (for some models)

Let’s consider each method in detail, taking into account the features of different lines.

1. Inclusion ANC via touch (sensory control)

This is the fastest way, but it doesn't work on all models. For example, Xiaomi FlipBuds Pro and Buds 4 Pro use triple touch on the touchpad on one of the headphones (usually the right one) to switch noise reduction modes.

Make sure the headphones are connected to the phone

Triple touch on the sensory zone (not on the ambusheure!)

Wait for voice or sound confirmation (squeak/vibration)

Repeat touch to switch between modes (ANC/Transparency/Off)-->

In the models Redmi Buds 4 Pro and AirDots 3 Pro control is slightly different:

• 🔘 Double touch – switching between ANC transparently
• 🔘 Holding 2 seconds - complete shutdown of noise reduction

If the touches don't work, check:

• ✅ Headphones sit tightly in the ears (the sensor may not work with weak contact)
• ✅ There is no moisture or dirt on the touch panel
• ✅ In the phone settings, gestures are allowed for headphones (Android: Settings) → Connected devices → Headphone settings)

💡

If the touch control turned off on its own, try resetting your headphones to factory settings. To do this, hold the button on the case for 10 seconds until the red indicator flashes.

2. setting up noise reduction through the application

To take full control of the ANC It is recommended to use the official appendix:

• 📱 Mi Earphones (for most models)
• 📱 Xiaomi Wear (for new headphones, for example, Buds 4 Pro)

Instructions for setting up through Mi Earphones:

2. Connect the headphones to the phone via Bluetooth.
3. Open the app and select your model from the list of devices.
4. Go to the Noise Reduction section (ANC) or Sound Effects.

2. Slap on the headphone icon → Sound settings.
3. Select Noise Reduction Mode and set the parameters.

In some models (for example, FlipBuds Pro) adaptive setting is available in the application. ANC — The system automatically adjusts the noise reduction level to the environment, so that it can be activated:

1. In the section ANC Activate the Adaptive Noise Reduction option.
2. Take a short calibration (the headphones will analyze the external noise).
3. Save the settings.

Voice control ANC

Table: Comparison of noise reduction in popular Xiaomi models

The table shows that the most effective noise reduction is implemented in FlipBuds Pro and Buds 4 Pro. ANC (AirDots 3 Pro is suitable only for suppressing monotonous noise (for example, a fan or air conditioner), but will not cope with sharp sounds (conversations, horns).

Frequent problems with ANC and their solution

Even when switched on correctly, noise cancellation may not work properly, and here are the typical faults and ways to fix them:

1. ANC It is switched on but does not suppress noise

If after activation of the function external sounds are still well audible:

• 🔍 Check the density of fittings – even a small gap reduces the effect ANC Try resizing the tips.
• 🔍 In models with level adjustment (Buds 4 Pro) increase the intensity ANC appendix.
• 🔍 Update the firmware of headphones through Mi Earphones – in older versions, noise reduction algorithms work worse.
• 🔍 If you have FlipBuds Pro headphones, calibrate it. ANC: Settings → Noise suppression → Sizing.

💡

To check the work ANC Use the test: turn on the function in a quiet room and hold the headphones to a source of monotonous noise (for example, a hair dryer.

2. extraneous sounds (whistling, hissing) when switched on ANC

Some users complain of background noise (high-frequency whistling or hissing) when noise cancellation is activated.

• 🎛️ Incorrect level adjustment ANC — Try to reduce the intensity in the application.
• 🎛️ Bad seal - check the bulges for damage.
• 🎛️ Hardware restrictions in budget models (AirDots 3 Pro) ANC often accompanied by side noises.

If the whistle doesn't go away:

1. Turn it off. ANC and use passive soundproofing (tightly inserted ambushes).
2. Try to turn on Transparent Mode – sometimes it works more stable.
3. Reset the headphones to factory settings (hold the button on the case for 10 seconds).

3. ANC spontaneously shut down

If the noise reduction is turned off after a few minutes, the reasons may be as follows:

• 🔋 Low battery charge — ANC It consumes a lot of energy, and at levels below 20%, the headphones can turn off the function automatically.
• 📱 Bluetooth Profile Conflict – Remove Headphones from the List of Connected Devices and Re-Pair.
• 🔄 Automatic Mode Switching – FlipBuds Pro has a Smart Switch feature that can disable ANC conversationally.

To avoid spontaneous shutdown:

1. Charge your headphones to 100% before use ANC.
2. In Bluetooth phone settings, turn off the low latency audio option (LC3) — She may be in conflict with ANC.
3. In the Mi Earphones app, deactivate Auto-Disconnect ANC When talking (if there is an option).

💡

If the problem is ANC It's saved after all the manipulations, check the headphones on another device, and if it's working properly, the problem is with your smartphone settings.

How to extend work ANC chargeless?

Active noise cancellation significantly reduces the battery life of headphones. for example, Xiaomi FlipBuds Pro without ANC They work up to 7 hours, and with noise cancellation on, they only work 5 hours:

• 🔋 Use it. ANC Only in noisy places (in quiet environments, turn off the function).
• 🔋 In models with level adjustment (Buds 4 Pro) choose the middle mode instead of the maximum mode.
• 🔋 Turn off Transparent Mode if you don’t use it – it consumes additional energy too.
• 🔋 Charge headphones in the case every time 2-3 high-hour ANC (This will prevent complete discharge).

It is also important to note that cold weather reduces working hours. ANC. Lower temperature +10°C battery capacity drops on 20-30%, In winter, the headphones will run out faster.

Comparison ANC in Xiaomi and other brands

Many users are interested in how much noise reduction in headphones Xiaomi is inferior to the flagships from Sony or Bose.

As you can see from the table, Xiaomi offers a price-performance ratio close to Apple, but is inferior to Sony and Bose in depth noise suppression. However, for most scenarios (metro, office, plane) 40 dB in FlipBuds Pro is enough. ANC It’s a service that most budget competitors don’t have.

If you want maximum noise reduction, Sony is worth considering. WF-1000XM4 Or Bose QuietComfort, but their price is in the 2-3 For everyday use, Xiaomi remains one of the best options in its segment.
