Noise canceling technology relies on repetitious noise. It senses the repetition and anticipates by generating an out of phase cancelling noise. Opening drawers and walking around noises don’t fit this bill. Engines running or maybe a repeating beat in music might qualify. At any rate, the solution is blocking.
Yes, I saw your opinion that, you're welcome to hold it while I continue to enjoy my Bose QC-II's, which I find do a very credible job of cancelling out non-repetitious noise. Fireworks, even! Spectacular with jet noise, too, which also is not repetitious.
