Panasonic has introduced the RP-HC700 noise canceling headphones, which, according to the company, reduce outside noise by 92% (22dB at 200Hz*). They are designed to filter out background noise by generating a signal of the opposite phase to effectively cancel it. Additionally, the headphones reduce low frequency noises such as the drone of a plane's engine or a loud air conditioning unit. The noise-canceling feature can also be switched off to allow the user to converse or to reduce background noise by virtue of the headphone's comfortable insulated housing. When the noise canceling effect is off, the headphones can still be used as normal headphones.

"Whether used to block out sound while on an aircraft or to create a tranquil environment so you can enjoy your music, these new headphones are up to the challenge," said Tom Hantson, Panasonic's national product manager. "With the RP-HC700 noise canceling headphones, even a crowded flight feels like a private flight."

These headphones feature large, 40mm drivers with Neodymium rare-earth magnets. The diaphragm is made from natural fiber bio-cellulose which the company claims has the sound velocity advantages of both aluminum and titanium, along with the warm, delicate sound that a paper diaphragm provides.

Boasting ergo-design earpads made of synthetic leather, the RP-HC700 also offers a swivel mechanism enabling folding for compact storage, and a protective carrying case. They operate on one AAA Alkaline battery and have a frequency response of 8Hz - 22kHz.

The RP-HC700 noise canceling headphones are currently available, with a suggested retail price of $199.99.
