But now I'm a believer. A few years ago, I'd bought some cheap Sony noise cancelers. They were good for blocking some constant noises like a dot matrix printer or fan, but didn't touch things like office chatter. I work in a small office and several of the people around me are doing customer support over the phone and sometimes with the ever annoying speaker phone. Its a necessary evil sometimes. And one lady next to me is very loud on the phone.
The Sonys started developing shorts and I might be getting more cranky in my old age as the talking became more bothersome. One day last week, I had enough and went to Best Buy. These might be the best thing I ever bought. With a little music or talk radio I can barely hear any noise around me. It has to be something very sharp, and then its muffled in the headphones.
No one else here may have a need for them, but I would recommend them to anyone.
