The noise cancellation feature on Xiaomi devices is a frequent source of controversy among users. On the one hand, it improves the sound quality during calls and video recording, eliminating extraneous noises. On the other, many complain about unnatural voice processing, sound artifacts or sudden loss of low frequencies. If you encounter such problems, this article will help completely disable noise cancellation on smartphones, headphones and even Xiaomi TVs.
It's important to understand that noise reduction algorithms work differently depending on the device model and firmware version. For example, on smartphones with MIUI 14/15, settings can be hidden in different menu sections, and in headphones Xiaomi AirDots or Buds - require special gestures or Mi Home application. We will look at all the current methods, including hidden options for power users.
Before you start shutting down, check if the problem is really noise cancellation, and sometimes similar symptoms cause:
- π Faulty microphone or speaker
- π± An outdated firmware version MIUI
- π§ Incompatibility of Bluetooth codecs
- π Battery savings (limits performance)
If the sound quality has not improved after the noise reduction switch is turned off, it is worth checking these factors.
1. Disable noise reduction on Xiaomi smartphones (MIUI 12-15)
On most modern Xiaomi smartphones (including Redmi Note 12, POCO X5, Xiaomi 13), noise cancellation is controlled through microphone settings. However, the path to these settings may vary depending on the MIUI version and regional firmware.
The standard method (for MIUI 14/15):
- Open the Settings app β Sound and vibration
- Scroll down and select Sound Quality or Sound Effects.
- Find the Microphone section β Noise suppression
- Switch the slider to the off position.
If there is no such item, try the alternative path: Settings β Additional β Special features β Improvement of sound.
On some devices (e.g. POCO F4), noise cancellation is activated automatically during calls, to turn it off globally:
Settings β Applications β Application Management β Phone β Permissions β Microphone β Additional settings β Noise reduction (disable)On the firmware for India (MIUI IN), this option can be called βNoise Cancellationβ and hidden in the developer menu.
β οΈ Note: On HyperOS devices (new shell instead of HyperOS) MIUI) The way you've got the settings has changed. Use the settings search for noise reduction, because the menu may be different from the usual menu. MIUI.
2. Noise reduction in Xiaomi headphones: AirDots, Buds, FlipBuds
In Xiaomi wireless headphones, noise cancellation is implemented at the firmware level of the device, and its settings depend on the model. For example, in Xiaomi Buds 4 Pro there is active noise cancellation (ANC), which can be adjusted through the Mi Home app, and in Redmi AirDots 3 only basic noise filtering when calling.
The general switch-off algorithm:
- π± Install the Mi Home app (for older models) or Xiaomi Earbuds app (for newer ones)
- π Connect your headphones to your phone via Bluetooth
- π§ In the app, select your headphone model β Sound settings β Noise suppression
- π Select Off or Transparency (if available)
For Xiaomi FlipBuds Pro, manual gesture control is also available: tap the touchpad three times on one of the headphones to switch ANC modes.
If the app doesn't see the headphones:
- Remove the device from the list of conjugates in Bluetooth settings
- Reset the headphones to factory settings (usually by pressing the button for 10 seconds)
- Reboot your smartphone and reconnect.

3. Hidden settings: engineering menu and ADB-team
If the standard methods do not work, you can use the engineering menu or ADB-These methods are suitable for advanced users and require caution.
Method 1: Engineering menu (MTK-chip)
- Open the phone app and type ##36446337##
- Go to the Hardware Testing section β Audio β Mic Test
- Find the Noise Suppression option and turn it off.

Method 2: ADB-teams (requires PC)
- Enable USB debugging in the developer settings
- Connect your phone to your computer and execute the command: adb shell settings put global. noise_suppression_enabled 0
- Reset the device
To return noise reduction, replace 0 with 1.
β οΈ Attention: Incorrect use of the engineering menu can cause malfunctions in the microphone or speakers. Before experimenting, back up your data via Settings β Additionally. β Backup.

4. Noise suppression on Xiaomi TVs (Mi TV, Redmi TV)
In Xiaomi TVs, noise cancellation is usually activated automatically when external microphones are connected (for example, for Karaoke) or when using built-in microphones for voice control.
Instructions for Mi TV 4S/5X and newer:
- Press the Settings button on the remote β Sound
- Select the Microphone β Sound Processing
- Turn off the parameters: π€ Noise suppression π Echo compensation πΆ Auto-setting volume (can affect sound quality)
On some models (e.g. Redmi Smart TV X55), these settings are hidden in the Developer section, which is activated by clicking on the Software version five times in the system settings.
If you use an external soundbar or Xiaomi soundbar, noise cancellation can be controlled through the Mi Home app:
- π± Open the app and select your TV.
- π Go to the sound settings. β Additionally.
- π Turn off speech processing and noise filtering
5. Problems after switching off noise reduction and their solutions
In some cases, turning off noise reduction can lead to unexpected consequences, and here are the most common problems and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The microphone is not working. | Failure of the driver after changing the settings | Restart the device or reset the microphone settings through the engineering menu |
| There was a background noise (hisping) | Hardware defect of the microphone, reinforced by the shutdown of filters | Check the microphone on another device or contact the service |
| Low volume recording | Disabling noise reduction reduced signal amplification | Manually increase the sensitivity of the microphone in the sound settings |
| Artifacts with Bluetooth calls | Codec conflict (e.g., aptX vs SBC) | In Bluetooth settings, select Sound Quality Priority |
If the sound quality of your calls has deteriorated after the noise cancellation has been turned off, try an alternative solution: instead of completely turning off the filter, reduce the aggressiveness of the filter. For example, the Xiaomi 13 Pro has modes:
- π High (maximum filtration)
- π Average (balance between purity and naturalness)
- π Low (minimum processing)
Often, the Low mode is enough to keep the natural voice without artifacts.
π‘
If you record videos or stream frequently, create a separate audio profile in the SoundAssistant app (available from the Mi App Store) that allows you to quickly switch between microphone settings without diving deep into the menu.
6.Alternative ways to improve sound quality without noise cancellation
If you have turned off noise cancellation, but the sound quality is still not satisfied, consider these options:
For smartphones:
- π€ Use an external microphone (e.g. Xiaomi Mi Lavender or Mi Lavender) BOYA BY-M1), plugged USB-C or 3.5 mm (if connector is available)
- π± Install audio recording apps with manual equalizer settings (such as Voice Recorder Pro or Hi-Q) MP3 Recorder)
- π§ Turn it on. HD-call-up SIM-Cards (available for VoLTE-enabled operators)
For headphones:
- π§ Update the firmware of headphones through Mi Home β new versions often improve the algorithms of sound processing
- π Try connecting your headphones to another device (like an iPhone or MacBook) to check if the phone is having problems.
- ποΈ Use a uniform preset in the sound settings (sometimes user settings degrade the quality)
For TVs:
- πΊ Connect an external sound system (e.g. Xiaomi Soundbar) β it often has its own sound processing algorithms
- π In the sound settings, select Movie or Music instead of Speech (the latter aggressively suppresses the background)
- π‘ Check the signal quality. HDMI-ARC β A bad cable can cause artifacts
π‘
If you use a device for professional recording (podcasts, streams), consider buying specialized equipment. Xiaomi smartphones and headphones are not designed for studio sound quality, even with noise cancellation turned off.
