I don't doubt that others are having "fart" issues with their CRBN ...
I'm 7 months and change in with my set, which I'm pretty sure are the 2nd "true retail set" in the US ... and I only get the "electrostatic farts" if I'm careless putting on, or taking off, the CRBN ... or deliberately try to induce it. They're no worse, for me, than my SR-007 MK2, SR-009S or SR-X9000. I can make them "fart", but I can do that with any electrostatic headphone.
But ... in any "normal" listening scenario, including drinking, and the odd snack, I get no "farts"; including when taking the (powered) headphones on or off.
I'm not a "headbanger", so that may change things for some.
I'm in Florida, so humidity is pretty high here (though it's about 43% in my house). And I seem to have a head size/shape, that corresponds well with whatever various headphone manufacturers use as a "standard". These may be salient factors.
Essentially, I don't find my set of the CRBN any more, nor less, sensitive to "electrostatic farts" than any other electrostatic headphone.
Just my $0.02 ...
