Title: Not worth it!
Review: I purchased these a few months ago. It does NOT cancel out noice, it may reduce it, but only slightly. You have to turn up whatever device you're using them with, they were actually quieter than my plain old headphones. I don't think the cord is long enough & when working out the "noise cancelling" device bounces. Recently it started to make a crackeling noise when the "noise cancelling" device lightly bounces of something. The only good thing I have to say about it is that even when working out the ear buds pretty well stay in your ear, and no foam to get all sweaty.
Is the review positive or negative?
