Query: Not worth the money

I was just given a pair of these for my birthday, and I have to say they are going right back.With Noise canceling turned off everything sounds muted and not even close to the quality that my $20 Sony's do.With Noise Canceling turned on, suddenly everything is bright and crisp and almost, but not exactly hiding the static.Now, if I want static, these are great, if I want to always run the noise canceling, they are outstanding. But, otherwise, I would never recommend them.
