Title: Don't waste your time with these
Review: Not worth your trouble.The sound quality was awful, big step down from the stock iPod ear phones.The "noise cancellation" function does no such thing. All it does is add a hissing sound and bump the volume up a tad. No detectable cancellation whatsoever.
