Does the noise cancelling earphone function continue to operate?

noise cancelling earphones home-appliances

I'm sensitive to sound, so I'm thinking of buying noise cancelling earphones for study.

Is the noise cancelling function still working?

Or does it work only when I turn on a small music?

I don't know if all the products are the same, but from my experience of using Boss and Sony products, noise cancelling is done as soon as earphones are turned on.

If you think about the noise cancelling product, there's no answer but the boss
I'm touched when I first did noise cancelling as the boss
But after some time, noise cancellation doesn't work as well as you think
I can't really hear what people are saying, but I can hear them making sounds
It's better not to expect too much

It's working whether I turn on music or not
If I don't turn on music, I can hear the outside sound better than I thought
