Listen in peace to your music! The Mutant NC102 noise canceling headphones offer an unparalleled value. The 18dB reduction at 300Hz is on par with high-end "professional" models, but at a $200 discount, and blows the other models in the "consumer" range out of the water! The soft cushioned earphones provide hours of comfort, while the active noise canceling provide hours of peace! Why pay more, for less?
