General Information
No matter where you go, enjoy peace and quiet with the MDR-NC22 Noise Canceling headphones. These compact and comfortable bud-style headphones can reduce noise by 75 (12dB at 200 Hz) and the 13.5mm driver units produce powerful sound. Perfect for tuning out noise at work, traveling, or even when you are trying to sleep in a loud environment. The noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headphones. Additional features include an in-flight adapter, compact battery box and it even comes with a carrying pouch.
