W=VxA

Not sure where you get 4W=2VxA

For a constant resistance as voltage increases current also increases proportionally (Ohm's law, I=V/R).

As current also increases proportionally, the increase in power is the square of the voltage increase.

It's also the square of the current increase, you can use that either.

But you can't have voltage increase with no current increase, they are linked. Unless there is a proportionate change in resistance with increasing voltage, which there isn't in headphones.

P=V^2 /R -> V(x2)^2 /R(no change) you get a P(x4) change.
