M4B is a file extension for an MPEG-4 part 14 audio layer audio book container file format used by iTunes. An M4B file is very similar to an M4A file but specified for audio books. Programs that can open M4B files include iTunes, Windows Media Player and Roxio Creator. So if you want to play it in Sansa Fuze, you'd better remove the DRM from the .M4b with some audiobook converter and convert it to common MP3 format.

Audiobooks purchased from Audible encoded with M4P files are encrypted FairPlay DRM technology. If you would like to convert audiobook DRM M4P to MP3, you need to remove DRM protection from these protected files.
Here, I high recommend AudFree DRM Audiobook Converter for Mac to remove DRM protection and convert DRM M4P files to MP3 directly with this one-stop tool. Besides, you can use this software to convert audiobooks DRM M4P to MP3, AAC, FLAC, MAV, etc without touching original files.
