I've felt like you, that video/audio is too slow and cumbersome, and so have eschewed it as a learning method, except as background for some other task. I'll have to give his 2x method a try.
I could see an opportunity for a "Pocket for audio" app, that (1) saves a clip for listening at a good time, (2) auto-transcribes it so you can scan for content quality or clip the part you want to hear, and (3) makes it easy to speed through at 2x or skip dull parts.
