I was wondering what everyone's expereince and opinions were on noise canceling headphones. My manager has the Bose ones. They are pretty decent for what they are suppose to do. I only hear a little feedback, but I think its because her laptop was causing it - not the headphones themselves. I stood next to an AC unit which is normally quite loud, and I could not hear it at all. I know Sony makes some, but I have never tried them. Has anyone tried Sony or any other brands? Are there some new models coming that I should wait for? I fly a lot, so I'm longing to get some. Thanks in advance.
