Most podcasts I tried were way longer and less information-dense than the YouTube channels I mentioned. I don't want to listen to 2-hour conversations with content that can effectively be summarized in 10 minutes or less.
I think you're asking for something which doesn't really exist, then.
Here's an idea - just listen to audiobooks. If you're not interested in podcasts and you're not interested in videos, I'm not sure what other options there are. People don't generally make "audio-only" YouTube channels because people who want audio-only entertainment normally choose podcasts.
Further, if your only experience with podcasts is 2h conversations which could be summed up in 10min, then you really just haven't explored enough I'm afraid. The channel you mentioned, Economics Explained, has a great podcast.
