Sandisk Clip Sport audiobook problem

Rather than blaming Sandisk, you should blame Audible. I don’t know why they need to use such huge files for audiobooks, and why they can’t break up an Audiobook into a number of files. i don’t use audiobooks, but do download podcasts. Many that I download are already at 32kbps, but those that are at a higher bitrate I convert down to 32kbps before putting them on my player. There is no need for high bitrates for spoken word files. For music a bitrate of 256kbps or 320 kbps is recommended. For voice files though, 32kbps mono is fine.
