Title: Fair, cuts out low noise, adds a high hiss
Review: I got a pair of these in a bundle. I tried them standing next to a machine like a low level noise (like an A/C or dehumidifier). It noticibly cut out about 70% of the machine noise. It had the same effect when used next to my PC which has several fans.Unfortunately, it also added a high-level snowy hiss. Although this hiss is not loud, it is noticeable and negates much of the value of using them.Also, as noted by several people, they are not particularly comfortable. Plus, when the cheap plastic frames moves across your head or bumps into the chair behind your head, these noise are transmitted through the hollow plastic.These are my only esperience with noise-cancelling heafphones, so I can't really contrast them with anything else. I probably wouldn't pay $50 for them, though.I did try them with a new battery and both with and without a music source attached.
