Quiet Zone⢠2000, the ultimate in noise reduction stereophone. Never before, on the consumer market, has there been a noise cancellation stereophone like the Quiet Zone 2000. Combining the finest elements of stereophone sound reproduction with the latest in active noise cancellation technology, Koss has developed a solution to quieting a noisy world.
With the ability to reduce noise by up to 20dB, the Quiet Zone 2000 is the most affective noise reduction system available to the consumer today, Paired with a top-of-the-line stereophone, the QZ2000 also delivers exceptional sound reproduction to the most demanding music lover.
The QZ2000 creates an invisible shield between the listener and the droning sounds of the world by stopping low frequency noise before it reaches the ears. The tiny microphones embedded in the earcups read the surrounding low frequency noise and transmit information about those undesirable sounds to a processor in the pocket sized control case. The processor, in turn, generates mirror image "anti-waves" that are 180 degrees out of phase and relays those anti-waves back to the stereophones. When the offending sound waves encounter the waves generated by the QZ2000, the two counteract each other at the wearer's ear. The offending hum and buzz is reduced and a peaceful listening environment is created where once there was only noise. Lawn mowers, jet engines, crowded environments, vacuum cleaners, computer fans or any other low frequency noise below 1000 Hz is reduced by an average of 10dB. Noise reduction is even greater for noise below 200 Hz, offering at least 15dB of protection against low frequency noise.
The stereophones of the Quiet Zone 2000 offer the ultimate in portable stereo sound reproduction. Featuring neodymium iron boron magnet structures and mylar diaphragms 16 microns thick, the Quiet Zone 2000 stereophones deliver the richest, deepest bass performance found anywhere in a portable, supra-aural design. Oxygen-free copper voice coils transmit a clear signal for virtually distortion-free listening. With a frequency response of 15 - 20,000 Hz, the Quiet Zone 2000 delivers outstanding sound reproduction from any audio source. Foam ear cushions provide an open, hear-through sound so listeners can keep an ear on the world while blocking out distracting background buzz. Completely collapsible, the QZ2000 stereophones fold up for protected, convenient storage.
The compact control case of the QZ2000 is smaller than any of its competitors for lightweight and convenient portability. Paired with the durable, lightweight QZ2000 stereophones, the unit makes a perfect travel companion to a portable CD or cassette player. Toss it into a purse or carry-on bag. Tuck it in a shirt pocket. A 2-pin adapter is included with the QZ2000 for use with many airline in-flight audio entertainment systems.
The QZ2000 uses 2 "AA" batteries (included). Highly efficient circuitry extends battery life up to 200 hours of peaceful listening pleasure. A red LED battery status light indicates 30 more hours of use until battery power is exhausted. A green LED indicates that the unit is "on."
The QZ2000 is guaranteed for the lifetime of the user under Koss' No-Questions-Asked Lifetime Warranty -- the only warranty of its kind in the electronics industry.
