So by your reasoning mblackey, if I built a twin aisle 150 seater aircraft which incorporated a totally silent cockpit and cabin, fur lined head rests, fully reclining leather seats, individual air-conditioning controls, IFE in every seat back, shag pile carpets and other such luxuries, the airlines would beat a path to my order book?
Maybe if they were very stupid, they would.
They go for the cheapest aircraft that fits their needs, not the most decked out, bells and whistles bit of slick that will admittedly get the job done but at what cost?.
Your logic is about as hair brained as most other people's who waste their money on expensive and unnecessary fripperies.
Buying an expensive headset makes a statement; I'm a professional pilot so I need a professional headset, nothing more.
