I'm curious about the function of noise cancelling headphones or earphones.
Does noise cancelling block all sounds
Or do you choose and block only noise that people think is noisy, such as airplane noise?

I don't block all the sounds
I couldn't block it with the feeling that I used it before, so I could hear the sound
I've heard that BOSS products don't block people's voices because they might have important sounds
I'm definitely good at blocking airplane noise
It's surprisingly hard to block people's voices, but I'm not sure if it's because I'm not good at it or not
The noise doesn't go away completelykk
It's like listening to sounds in the water
The no-can function blocks the low frequency band from 1000 to 1500 Hz
So it's hard to block the high frequency band
Kernel-type earphones block high frequencies, so if you use kernel-type no-can, they block everything
But that doesn't mean it's perfect
