Watching Darma Talks on 2x Speed I really like Ajahn Brahm's Darma talks on YouTube. But, I can perfectly understand what he's saying on 2x speed.

Am I losing anything by listening at this speed or is it ok as long as it's not for any other reason than I can understand it so I can watch two in the same amount of time as one?
I have done the same thing for slower speakers. In my opinion, it's just fine to speed up your listening as long as you grasp the content.
