QZPRO Noise-Cancelling Headphones


Product Description

The Koss Quiet Zone QZ PRO Headphones feature both active and passive noise cancellation. For passive noise reduction, The QZPRO features soft leatherette, closed cushions, which create a tight seal around the ear and reduce ambient noise. Active noise-cancellation circuitry uses tiny microphones that sample surrounding noise and transmit that information to a processing circuit, which counteracts the unwanted noise to create a quiet listening environment. Two AAA batteries are required for active noise cancellation and the noise-cancellation feature can be easily turned off with the flick of a switch. The Koss QZPRO deliver a frequency response of 40 Hz to 20 kHz, providing the listener with both deep bass and a balanced midrange.
