Biggest audio hoaxes

It's All Good.    Happy Listening!

MC, that does appear to be a coherent explanation from Geoff.  He wasn't always just full of (admittedly pretty funny) snark.  Do you get to pick the hat you eat?

All those scams pale in comparison with by far with the two greatest perpetrated by Bose. #1 is the Bose 901 direct/ reflecting bogosity, all versions.
#2 are Bose noise canceling headphones. In this case it's not that the technolgy doesn't work, it does, but that the R&D was paid for by you, the US taxpayer, to the tune of over $100 M dollars. Bose received a DoD contract to develop noise canceling technology, and after failing to deliver any usable device or technology the DoD pulled the plug. The $100M written off.

Years later, a new engineer happened across the basic research, took on the project anew, and the Bose noise canceling headphones were shortly on the market, based on the original taxpayer funded research. Bose has never reimbursed the government a single dime. Your tax dollars at work. 

I would love to have some kind of noise cancelling system for a listening room. A bit pie in the sky, but people have spent a lot for what seems a lot less plausible.

If he is a fan of Mexican, I suggest a sombrero.
