While it might be a bit more difficult to understand what's going on in an audiobook (since you're lacking any visuals clues), density will be much higher: There won't be any periods of silence, music or prolonged pauses - which is of course very common in German TV shows and movies.
That's why we'll start with an two easy German audiobooks for beginners and then talk about three more intermediate ones.
German Audiobooks for Beginners
1. Die unendliche Geschichte
Starting off with a well-known, fantasy epic for beginner readers (or listeners, rather), this audiobook begins with Bastian Balthazar Bux - a young and neglected boy, around ten years old - stealing a curious book from an antique bookstore, whilst trying to escape his bullies.
The book is a fanstasy novel called Die unendliche Geschichte, full of magical and mysterious creatures, and as Bastian reads it, he is literally pulled into it's world, becoming a central figure in the story.
However, this comes at a price, as he of loses touch with the real world, and his true identity. When he realizes this... is it too late?
A novel that celebrates the inspiring, nourishing effects of a healthy imagination, whilst recognizing the dangers of escaping into fantasy for too long.
2. Die Panne
When a traveller's car breaks down one night, he is offered a place to sleep, in the home of a retired judge who lives nearby.
That night, the host suggests they play a game together with a few of his friends, and hold a pretend trial, with the traveller playing defendant, to which the traveller agrees.
However, as the game progresses, the worlds of reality and play begin to blur, when actual details of the traveller's life are cross-examined and judged, without mercy.
The traveller is forced to face his wrongdoings and - ultimately - the verdict of the jury.
German Audiobooks for Intermediates
3. Die Rosemarie-Hirte-Romane
This audiobook includes two German crime fiction books by author Ingrid Noll, whose books are well known for their murder-committing, complex female protagonists.
Both tales explore the lives of headstrong women in love, and the bloody crimes they're willing to commit, to get what they want.
In the first, Rosie falls obessively in love with a stranger, and is ready to kill for his affection. In the second, Hella confesses to the murderous outcomes of her past rocky relationships.
Two sharp psychological crime thrillers, crackling with black humor and irony ⚡️.
4. Die vertauschten Köpfe
When Sita discovers her husband and his friend both decapitated in a temple, she prepares to kill herself too, when goddess Kali intervenes with an offer to bring the men back to life.
Accepting the offer, she mistakenly places the heads onto the wrong bodies, and consequently struggles to make sense of their entangled identities. Who is truly her husband? He who has his head, or he who has his body?
Die vertauschten Köpfe explores themes of identity and metaphysics, with this surrealist tale of an unusual love-triangle.
This little gem of an audiobook is packed full of short tales set all around the world, from Berlin to Tokyo, to New York, to Vienna... capturing quietly significant, life-changing moments of time - important decisions being made, coincidences and surprises experienced, lost love and loneliness - all wrapped in familiar Schirach-esque themes of crime and punishment.
It is a melancholic audiobook, meant to be listened to on a wet and stormy night. Perfect for the coming winter season.
