True Fidelity Active Noise Cancelling Headphones. Ideal for creating your own personal space filled with clear sound or nothing at all. True Fidelity Active Noise Cancelling Headphones feature award-winning noise cancellation and sound clarity technology in a basic design that folds down for taking outstanding audio quality wherever you go. They filter out background noise and reduce distortion so you always hear what s in the headphones, not what s going on around you. Enhanced sound quality and speech clarity. True Fidelity s LINX AUDIO technology creates high-frequency harmonics that enhance sound quality and speech clarity of difficult-to-hear words or notes, which increases the perception of loudness without increasing volume.
