How is noise related to wireless? I was not aware that wired headphones enjoyed any advantage there, and I can't see how they would.
The others are certainly wireless problems, but some people prefer wireless for a variety of reasons. Lots of manufacturers sell wireless headphones. To say that Apple created those problems makes no sense.
I never see people wearing headsets that place the microphone near the mouth outside of specialized settings, nor do I see people holding the microphone to their mouth. I suspect they generally want to keep their hands free.
I don't think the distance between the speaker and microphone matters. Canceling out the noise you're emitting isn't hard with modern signal processing.
