Which devices play Audible audiobooks but can't surf the web?

Amber wants her son to be able play Audible stories but does not want him to have internet access

As a child I had a cassette tape player. I could choose the music and stories I wanted to listen to alone in my room without my parents worrying about me accessing the internet.

My son loves listening to Audible stories on an old iPhone. I have blocked certain features but he keeps finding things to do that I haven't blocked. I want a device that can download a lot of Audible stories so he can choose what to listen to, but without all the other temptations of an old phone or the risk of him going online. Amber

This is the age of the internet, and the trend is for every device to be online all the time. This started with PCs and then smartphones, followed by TV sets, games consoles and digital video recorders. Now we're getting connected cameras, fridges, doorbells and smart speakers, and the choice of products that can't connect to the internet is rapidly diminishing.
