i bet that they work the same way that the cd to cassette adapters worked except, instead of a stereo aux jack with continuous audio signal, it uses an digital to analog converter and the rest of it works the same way.

here’s video from on of my favorite youtubers who does a really great job at explaining how consumer electronics work and he explains how the cd to casette & bluetooth adapters work: https://www.youtube.com/watch?v=dH4n8fUjtLQ

Same way they did when it was a wire to a 3.5mm plug, just a Bluetooth module now.

As far as I can tell, this literally does not tell you how it works. It says there is a Bluetooth receiver in the cassette, the cassette portion works like a cassette, and that there is “magic” that happens between the Bluetooth and cassette portions.

Where the magic happens is with the Bluetooth receiver/unit within the adapter, which is able to receive a signal from your phone (or other Bluetooth-enabled device) and then use the old-school magic of the cassette to play audio back via your car’s stereo.

That doesn’t really tell me anything. I’ve always assumed it takes the Bluetooth signal, converts it as needed, writes it to the cassette, and then the car reads from the cassette. But this doesn’t even say that. It sort of implies it though.

For what this article is trying to convey, it’s very bad IMO. All it does is talk about the very obvious parts of a Bluetooth cassette adapter.
