For passive noise reduction, the QZPRO feature soft leatherette, closed cushions, which create a tight seal around the ear and reduce ambient noise, all while retaining bass frequencies. Active noise cancellation circuitry embedded into each QZPRO ear cup uses tiny microphones that sample surrounding noise and transmit that information to a processing circuit, which then generates "anti-waves" to counteract the unwanted noise and create a peaceful listening environment. No need for noise cancellation? No problem. Turn it off with the flick of a switch.
Not only do the Koss QZPRO excel at noise cancellation and reduction, they deliver uncannily high quality sound. The dynamic element bears a full frequency response of 40-20,000 Hz, allowing these noise cancelling headphones to boast deep bass and balanced midrange. Because for Koss, performance is more than a priority. It's our legacy.
