Eli5 How does music from a live band for example travel through wires and digital formats yet sound exactly the same when coming out of my headphones?

Alright, buckle down for this one.
So. Sounds is the movement of atoms. Specifically the pressure changes the movement of atoms and molecules cause by moving.
With that in mind, our ears picks up on those pressure changes and our brains puts them into information we call sound.
Microphones do the same sort of thing. There’s a small sheet of very thin metal that vibrates when sound hits it, which is then converted into depending on what type of microphone either fluctuation in voltage if you have an older microphone, or directly into ones and zeros if you have a digital microphone.
That fluctuation in voltage or the one and zeros can be fed into a speaker, speakers have the same basis of the thin sheet of metal that vibrates the right way to replicate what the sounds wave looks and sounds like.
Old type cables work the same way two tin cans on a string do. But with electrical signal rather than direct vibrations of the string.
I know i missed some more technical stuff here, ask away if you have any questions.
