Material Audiobook Player for Android
I think it is one of the good player having good play speed controller but lacking in some feature 1 it must have equilizer(please add it) 2 it must have floting subtitle mode(which can be downloded from anywhere)
Great for playing audiobooks. You just select you book and it picks up right where you left.
Best free player I've found.

A fantastic audiobook app, does exactly what it says: great rendering of your mp3 book collection for free, with minor non-invasive ads. Forward and skip functions are present, as is a sleep timer. What I love most is that it allows you to switch between audiobooks without losing your place in the book, so you can start where you left off - not the case with music players. Highly recommended.
