I'm sure he imagined himself wearing the mic-less headset.
Someone back on page 1 said they'd want such a device for issuing safety briefs: Nice idea, but safety briefs should, in best practice, include an acknowledgement from the passenger that they have understood and present an opportunity for the passenger to ask questions. Can't do that if you can't talk, nor could a pax say "I say Biggles, is that cloud of black smoke meant to be pouring out the back of Number 2, what?" - which I'm sure no Omnipotent God of the Sky who frequents PPrune would need, but I have heard there are some pilots out there who might not be PPruners...
A smart comms box that can cut the pilot clear of cabin chatter when he needs to is a better idea, albeit more expensive, and means I have a cabin full of spares when mine ****s itself mid-flight.
But it did feel good to be rude to cadetkid, didn't it? I wish I could join in but I'm short of witty retorts
