Kensington noise canceling headphones reviewed

PC Mag's got a review of Kensington's new low-cost noise canceling headphones which, unlike some other
competing headphones, appear to actually cancel some noise.  Don't expect them to completely drown out the construction crew working outside, but for making long airplane flights a bit more bearable, they do seem to get the job done.  You won't be getting
Shure quality audio from them either, but for $40 you get what you pay for.
