After measuring the headphones with an LCR meter, is there a way to
take the inductance, capacitance and resistance to find the AC
impedance of the headphones at 1KHZ?

Hay OM:

I wondered what the impedance of a crystal headphone would be. I guess
just the capacitance and inductance of the wire going to the crystal.
And at 1000 cycles that would be way up there.

I can bet for a certainty that 32 ohm headphones will be 32 ohms of
impedance at 1000 cycles. Just think how much the inductance and
capacitance will figure into the equation? Under 1% I bet at 1000
cycles.
