The Koss QZPro -- Affordable Noise-Cancelling that works! ”



Jul, 2010

Consumer review by: (



These are probably the worst headphones I have ever listened to. The "noise cancellation system" blocks nothing; in actuality all it does is produce a high-pitched whirring noise that undercuts anything you listen to with them.
