GREAT STOCKING STUFFER! - $40 off Sony MDR-NC6 Noise-Canceling Headphones (now $39.99 with FREE shipping) Posted Monday, December 19, 2005 by David
Great stocking stuffer! Small enough to keep with you at all times and ideal for achieving peace and quiet in planes, trains, buses, and cars, the Sony MDR-NC6 Noise-Canceling Headphones reduce perceived outside noise by more than 70 percent (up to 10 dB at 300 Hz) so you can hear musical nuances against a quieter background.
The headphones' noise-canceling circuit senses outside noise using tiny, built-in microphones and sends an equal-but-opposite canceling signal to the headphone drivers, effectively blocking solid-state (continuous) noise from 40 to 1,500 Hz. It's especially effective on noises like air-conditioning systems, freeway rumble, and airplane engines (from a passenger's perspective).
The switchable noise-canceling circuitry runs for approximately 30 hours on a single AAA alkaline battery. When noise canceling is off, the headphones continue to function for standard music listening (and with slightly better sound quality). The headphones' neodymium-magnet diaphragms deliver powerful sound.
The Sony MDR-NC6 Noise-Canceling Headphones and their swiveling earcups fold for easy storage, and a special supplied adapter facilitates use of the headphones with an airplane's audio system.
