Observe: take a short cable (or a piece of thread), hold it straight at each end with two fingers by the wire; at one end, roll the cable along its main axis between the two fingers; a loop forms, purely through created stress.
Now, with a longer cable you just accumulate such loops by iterating over the length; stress can be relieved by accompanying the cable while twisting: there should never be any resistance felt.
If done correctly the folded cable should be able to lay flat on a table and not move a millimetre. Note that there's a "natural" radius that is best respected.
One could stack a bunch of those in a box and they basically won't mix unless massively shaken, but to make sure one can tie a single point of the loop to eliminate lateral slack.

While this works, it’s mostly useful for storing naturally curled wires/hoses. The downside is it becomes twisted again by pulling straight.
The “accordion” method actually counteracts knotting because it forms a sort of an amorphous spring that is unstable outwards rather than inwards (careless winding) or just being stable (twisting). I find it more useful as it never twists and tends to decay into a straight wire by itself. But ymmw, cause it tends to be all over the place in your pocket/drawer/etc. also doesn’t work for hoses cause they deteriorate at sharp folds.
The moral is just know your methods and where they apply and if that suits you the best.
You can also wind it while twisting the remaining of the cable on the opposite direction.
On a short cable like a headphone string, this is just a matter of holding the cable up so the plug can rotate freely. Then you can do anything, you won't accumulate stress. (On a longer cable that means putting temporary stress on the non-wound part of the cable. If it's too long, you need to remove it from time to time.)
Anyway, I've just printed a ton of cable-winders, for all sizes and calipers, and never thought about it again.
That's the whole trick: don't wind, twist.
