The management screen of Soundcore Liberty 4 Pro in the Soundcore app looks like this.
By sliding the 'ANC' bar in the center of the screen, you can adjust the strength of noise canceling and ambient sound capture on a scale of 1 to 10. The default setting is '5' ('Standard'), which means that neither noise canceling nor ambient sound capture is enabled.
You can increase the strength of noise cancellation by sliding the bar to the right of 'Normal.' There are five settings, from 6 to 10.
On the other hand, sliding the bar to the left from 'Standard' increases the strength of ambient sound capture. This also has five settings, from 1 to 5.
Also, when you tap Airplane mode, the air pressure sensor inside the earphones will be activated and the strength of the noise cancellation will be adjusted to match the current air pressure. There are two types of Airplane mode: 'Automatic' and 'Manual'.
Turning on the 'Wind Noise Reduction' switch can reduce noise interference caused by wind.
You can also customize the sound to suit your own sound preferences.
In addition, you can also change various operations of Soundcore Liberty 4 Pro.
Some of the Soundcore app's functions can also be performed by operating the touch bar on the case. In the video below, the case is opened and the touch bar is used to switch between ambient sound capture and noise cancellation, as well as adjust the strength of noise cancellation.
