Yesterday, the first part of the Oathbringer Graphic Audio came out. Its regular price for a digital version is $16.99, and you can also get it on CD as well. Graphic Audio has done many of Brandon's books and are highly regarded. It isn't just a usual audiobook. It has a full cast of readers acting out the dialogue, with music as well. You can listen to a sample to see if it's your sort of thing on the Graphic Audio page.
If you have these, let us know what you think of the graphic audios below!
