RE: A Mercedes and a bus...

No. There's no varying when it comes to the principals involved here.

This is not subjective or just someones opinion.

You clearly don't understand Common Mode Rejection.

You also don't understand audio signal.

When a microphone is in the presents of sound there will be an output signal.

If the microphone is single ended the signal will be represented by a voltage potential difference between ground and the one signal wire. If the microphone is balanced the signal will be represented by a voltage potential difference between the two signal wires.

Common Mode Rejection is the rejection of any signal that is common to the two balanced wires.

That can never be the audio single generated by the microphone because, as I have already explained, a balanced microphone's audio output is represented by a voltage potential DIFFERENCE between the two signal wires.

CMR does not reject voltage potential differences between the two signal wires, CMR rejects only voltages that are the same in each of the two audio signal wires.

I don't think I could have made this more clear.
