The Sony MDR-NC22 offers high-quality audio and terrific noise cancellation in a portable in-ear headphone. Powered by a single AAA battery, the MDR-NC22 features 13.5mm neodymium drivers to provide a rich, natural sound with a wide frequency response. The soft 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 75 percent. An airline adapter is included so you can use your headphones when you fly, and a carrying pouch is included for convenient storage.
