Don't get me wrong here. Your circuit is definitely a more eloquent solution being fully balanced and powered from phantom power. It will have much better performance in noisy environments and with longer cable runs.
I was just aiming for the simplest solution I could think of that would do the job.
If I was to use your circuit with an Apple headset though, I'd be inclined to replace the zener diode with a 5.1 volt one (1N4733) or even 4.7 volt (1N4732) just to play it safe.
