Noise Canceling Head phones 1.0

http://www.buyheadphones.us - The music from these selected "Noise Cancelling" headphones provides an enclosed sound system which emphasizes bold and clear lyrics and instrumentation. I was astounded by my ability to immediately recognize various subtleties that I had always listened to, yet not heard. My research has developed significant, objective, quantifiable differences between noise-canceling headphones and those that do not have this capability. Included in these comparisons, I specifically targeted enclosed ear covers compared with those headsets commonly referred to as "earbuds" and "earclips".
