I listen between 2x-3x, depending on the accent. You get used to it with time and the 1x sounds frustratingly slow.

I listen probably 4+ hrs a day, which is almost a book. I do it while exercising, drawing, gardening, or cleaning. I average another 2 hrs a day of physical reading, which is also almost a 300 page book. I'm guessing on the times though. I finish ~500 books a year and about 10-20% are audiobooks.
