I tried using qc15 at Cheongum Shop for a while, but it was a new world.
The noise suddenly decreased, so I thought I turned off the volume around.
I'm not sure because I used it for a while, but I'm hooked on noise cancelling.
I heard that qc20 is much better.
What is the performance of those who have actually used it?

It depends on where you use it.
If you use it in a quiet place, the sound decreases.
It can catch regular machine sounds.
But the sound of people making isn't completely silent kk
I heard it was originally built to eliminate aircraft noise.
Maybe that's why I used some of the noise cancelling functions on the plane, and among them, qc20 was the best.
It's almost quiet.
Most regular mechanical noises are well caught.
The vacuum cleaner was so loud that I used it while cleaning.
This wasn't as effective as I thought.
I heard that there is a noise response pattern.
I think I heard that the reason why I don't even catch people's voices is that I took it out of the pattern.
