Review of boss headphone noise cancelling function

pu1. It depends on where you use it. If you just use it in a quiet place, the sound decreases and you can catch regular machine sounds well. But the sound that people make is not that completely silent

OK

pu2. I heard it was originally made to eliminate aircraft noise, so I tried some headphones with noise cancelling function on the plane, and the boss was the best among them. It's almost quiet

OK

pu3. Most regular mechanical noises are good. The vacuum cleaner was so loud that I used it while cleaning it, but it wasn't as effective as I thought. I heard that there is a noise response pattern. I think the reason why I don't even catch people's voices is because I heard they took it out of the pattern
