Like everybody else here said…audiobookshelf is da bomb. I had an audible subscription for a while and found myself without the time to really listen to enough audiobooks to make it worthwhile so I cancelled. I know I could still access the audiobooks I purchased but I’m always concerned with these companies suddenly having a disagreement with a publisher and nuking a whole pile of media I paid for so I figured out how to download my purchased audiobooks locally to be listened to via audiobookshelf. Worked great.
They have a sync that actually works pretty well. As the product is still beta you can donate and get access to the sync service.
