So, I've been thinking for a while about one particular thing. Why is that that discourse that surrounds listening is so esoteric?

Like, don't get me wrong, there's plenty of things about pronunciation learning that are imprecise, say, those obtuse yt videos where, shall we even say, "tutors", themself don't even know IPA or basic linguistic terminology. As a result of that, you've got such abomination as "hard and soft" G or C, and that's got nothing to do with palatization or alike, nada. Or grammar - there's a lot of non-systematic, incoherent and made-up explanations of English grammar rules which confuse learners at the best and are plain wrong at the worst. Grammar teachers love their casuistry, God forbid, to streamline anything, and if they do then it's opposite extreme where things are too simplified.

But the thing is "the listening teaching" don't really know how to call it more eloquently is just something else. Every time when I've got to stumble upon a listening yt video or some article, they do disapoint me and regardless of that I'm still hoping and keep a-going, don't really know why or what for.

Like, every single time, it's either the same ephemeral garbage or painfully obvious life advice trash. It is garbage, trash, litter, waste, debris, refuse, dump, crap, rubbish and junk. All way through. Just gonna list the main culprits up:
1) Ubiquitous "listen more". Oh, really?
2) Listen to different speakers, topics, qualities, etc. That's that. That's almost as obvious as previous one.
3) Do or don't (they still can't decide, it seems) watch the thing with subtitles. I think they're helpful at the very start, but afterwards they will turd you down so it's better not to get into the habit of that.
4) Find a thing and listen to it on repeat until you understand it. Or alternatively listen to a thing, then listen again, the make transcription, then check it against the original. That's very cumbersome and time-consuming, albeit somewhat helpful.

Where are all good things? In my entire life, I haven't seen a single solid content piece on English listening. I'm not asking for some cure-all or free hard science content on the psychoneurology of auditorty perseption. But there's gotta be at least something decent. I mean, what do they teach in ling campus? I've seen people who are able to transcribe to IPA a random sentence in unknown language almost perfectly.

For context, I'm a C1, at the best, and regardless few years that I've been studying English there's still moments when I just don't get it. I can understand about 97+% of the GA, if it's spoken clearly and a speaker's next to me or mic. BrE, Scottish, AAVE or any other variety of the AmE, then it's closer to 90%. A If it's some scarce dialect or there's speech impediment, it drops ot 80-85%. But what really gets me is when it's "distorted". Like English on the radio and I mean the ham radio, or there's some sort of noise, like a phone call. I watched few police cam videos and I could barely get anything that that's said in the radio comms, even though it's just a few numbers and plain codewords.
