The MDR-NC40 noise-cancelling headphones from Sony provide a pleasurable listening experience for travel, or around the house. The lightweight foldable design features an adjustable headband and comfortable ear cushions to provide a comfortable, low-pressure fit.
Active noise cancellation technology helps to dramatically reduce ambient noise by up to 80 percent. The headphones operate for up to 40 hours on a single AAA battery. If desired, the noise cancellation can be switched off, allowing you to use the headphones without a battery.
Large neodymium drivers provide a rich, detailed sound response that puts you right in the middle of your music. A convenient airplane adapter is included for in-flight listening, and a carry case makes storage and portability a breeze.
