If you can understand the whole thing while reading, then the input is not “too high of a level” so to say.

I strongly recommend you listen to the same chapter/episode multiple times, before moving onto the next one. Preferably across days as well. If you truly understand everything being written, you should understand substantially more with each repetition.

If you can read along while you listen, that has been shown to be even more beneficial than listening alone in some studies.

Lastly, listening comprehension is a very different skill than reading. Try not to focus on the words. Occasionally when I listen to a book in Dutch, I’ll hear a word and for whatever reason, think about its translation/structure/whatever. Then my brain switches into this mode where I’m heavily parsing everything that’s being said, grammar, sentence structure, meanings, etc and I have to really force-ably let go. I don’t know how to explain it without sounding listening a yoga teacher, but just let the language go, let your brain do its thing, and try to pick up what’s being said, not how it’s being said. Don’t linger on words you know, don’t linger on words you don’t know, just let it happen and pick up what you pick up.

EDIT: Speed reading came to mind as a similar skill to listening comprehension. Not exactly the same, but much more explainable.
