Of course, the reader is a huge variable. I have had to crank up an audiobook to 2.5x-3x for one reader. Of course that is usually way too high to be comfortable. I do 2x quite often but 1.5x really is the best and feels the most natural. I can’t do 1x or it feels like the reader has a speech impediment.
1.5x is probably my happy medium where I can still take stuff in. 2x is just to fast for me. Age might have something to do with that as well.
