I gave it a go using the method where you derive a output impedance by finding the following values:
V1 - open circuit voltage while playing the 60Hz sine tone
V2 - voltage of the loaded circuit that I got by connecting IEMs and playing the same 60Hz sine tone
R - resistance of the load which in my case is 16 Ohm.
I used the calculator to avoid mistakes.
I got a result of around 13.71Ohm but I was confused by the Voltage readings.
V1 = 1.3mV
V2 = 0.7mv
I'm not sure if that is correct, all the online tutorials that talk about this in general have values that are in V and not mV.
Do my measurements sound plausible?
