Question about Active Noise Cancellation alternatives (fedia.io)

I've got a audio/tech question, maybe someone here might have some insight into.

I'm in need of noise cancellation for various and sundry reasons. i own a pair of BOSE ANC headphones which are tits, but have been looking for a pair of GOOD ANC earbuds that don't cost $300 bucks, and had an idea that all ANC appears to be, when you break it down, is sound that the earphones/earbuds produce which bounce around in the ear canal and hit the ear drum in certain ways as to "cancel" out various types of background noise.

Again the ANC on my BOSE are amazing. Does anyone know, or have even heard of (no pun intended) anyone who has produced "noise cancelling" sound files?

It seems as if noise cancelling hardware like earphones are producing sounds that cancel out noise, mp3/flac files of "noise cancelling" sound could be on offer somewhere.

Dunno, figured i'd ask. Hope this is the right place to do that, and I'm not breaking any rules, I didn't know where else to post this.

Afaik you have to replicate the same wave but in opposite "direction" (up/down sinus) to cancel out incoming sound so any anc earbuds have to have microphones and are dynamically shaping the sound.
