As I know, downloaded from Audible aa files can't play on the ordinary media player. To be honest, I think you can convert them to MP3 format and listen to your audiobooks on e250. As for the converter program. I recommend you can have a try with AudFree Audible Audiobook Converter, which is a professional software designed to convert *.AA files from Audible to MP3 losslessly. Besides, it supports to keep and customize ID3 tags to manage your playlist easily.
