Enhance your listening experience and reduce unwanted ambient noise by 87.4 percent with the MDR-NC7 noise canceling headphones.

Noise canceling headphones reduce ambient noise to provide a quieter environment for audio entertainment. The headphones have an inside microphone on each earpiece that works with electronic circuitry to create oppositely phased sound waves that reduce, or phase out, the ambient noise sound waves. The MDR-NC7 reduce up to 87.4% (9 dB at 300 Hz) of ambient noise when the noise canceling circuit is switched on, ideal for loud, noisy environments like planes, buses, dorms, etc. Listen With or Without Noise Reduction Convenient dual-use capability gives you the option of listening to your music with or without the noise cancelation feature, so you can enjoy unaffected music in quiet environments. This also allows you to keep using your headphones (minus noise reduction) when the batteries run dry. On-Ear Design Many of the noise canceling headphones out there are earbuds; these are ideal for someone who prefers an external phone. The phones rest gently on your ear, with an adjustable headband to get a good fit. And good sound--a neodymium magnet provides excellent power-handling, and 30-millimeter drivers deliver quality sound with a frequency response of 20 Hz - 30 kHz.
