QZPRO Active Noise Reduction Over-Ear Headphones Koss(r)

Specifications

• Packing the punch of passive and active noise reduction (ANR), the KOSS 184408 QZPRO Active Noise Reduction Over-Ear Headphones are the noise canceling headphones of choice for music lovers. Their comfort and collapsibility—not to mention sound quality—make them a favorite among travelers. 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
oise cancellation circuitry—embedded into each QZPRO earcup—uses tiny microphones that sample surrounding noise and transmit that information to a processing circuit. That circuit 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 Hz to 20,000 Hz, allowing these noise canceling headphones to boast deep bass and balanced midrange. Because for KOSS, performance is more than a priority.
