The Sony MDR-NC13 Noise-Canceling In-Ear Stereo Headphones offer high-quality audio and terrific noise cancellation in a portable design. Powered by a single AAA battery, the headphones feature 13.5mm neodymium drivers to provide a rich, natural sound with a wide frequency response. The vertical design and soft interchangeable eartips sit comfortably in your ear for a snug fit that helps to naturally block ambient sound.
When the noise-cancelling feature is turned on, the circuitry listens to the sounds around you with a built-in microphone and sends out an opposite signal to cancel the unwanted sound, effectively reducing ambient noises by up to 90%. The NC feature can also be turned off if desired.
The gold-plated angled 3.5mm plug provides compatibility with MP3 players, CD players and more, while the included airplane adapter lets you use your headphones when you fly. A carrying pouch is included for convenient storage.
