You can try to speed up vids or audio when listening to something. I started doing that while cramming stuff, using 1.25 - 1.5 playback speed. You slowly start speeding up things, as you get used to it.
Actually I am doing this. Listening to a lot of audio books on my daily commute I find most regular speakers a little too slow for my liking. Especially in English (I am German and found that English seems to be often spoken slower in audio books).
I do 1,2 to 1,25. I did 1,6 for a time, but lost the fun in it as it felt too much of a rush and self optimization (more books in less time) instead of the joy of listening to a great story or great insights.
