[Elecraft] Bose noise canceling headphones

[dw]

Ah!
I've always wondered how well Bose noise cancelling phones worked.
Do they really cancel noise external to the head-set?
I understand the concept...mic the external noise and mix it back into
the earphones 180 out of phase.
Just never got a chance to see how effective.

There are times when I have trouble with noises in the house, and I
would love it if the head-phones could totally cancel all that out.
But.... not sure how far advertised is from reality  :)
