Koss QZPRO QZ Pro Noise-Canceling Headphones
Packing the one-two punch of passive and active noise reduction, the Koss Quiet Zone QZ PRO 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 features soft leatherette, closed cushions, which create a tight seal around the ear and reduce ambient noise, all while retaining bass frequencies. Active noise cancelation 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 cancelation? No problem. Turn it off with the flick of a switch. Not only do the Koss QZPRO excel at noise cancelation and reduction, they deliver uncannily high quality sound.
