Title: Better than nothing, barely
Review: If you're looking for significant noise canceling activity, these are not the earbuds you want. There is a barely detectable decrease in outside noise when you switch them on. They mainly work by introducing a lot of background hiss and boosting the volume of the music. 10 dB ? Maybe if you glue them in with epoxy. Still, they are better than airline-supplied headsets. Just don't expect too much.
