Query: The Reviews are CORRECT!

I did an extensive search over a couple of months and concluded that Audio-Technica ATHANC7 Noise-canceling Headphones were the absolute best technology for the money. When I got them I was prepared to do a return if they weren't up to my demands but they were! I'm wearing them as I type this!They are not absolutely and emphatically perfect but they are as close as I could get. The guys at the Bose store throw spit ball at me as I pass by now.Amazon did a great job with the price and delivery.I note that the adverb for cancel can be either cancelling OR canceling.
