The MDR-NC7 headphones from Sony offer terrific sound quality combined with active noise cancellation, allowing you to enjoy your music in blissful peace. The technology inside the headphones listens to your environment, and then reduces it by over 85%, making jet engines and other constant noises fade away. A passive listening mode is available, allowing you to listen to music without the noise cancellation feature if the battery runs out. The headphones feature swivel earcups and a foldable design, allowing you to carry them easily for travel. A dual-plug airplane adapter is included for connecting to in-flight entertainment systems.
