Packing the one-two punch of passive and active noise-reduction, these Koss Quiet Zone QZ PRO headphones are the noise-cancelling headphones of choice for music lovers. Their comfort and collapsibility, along with amazing sound quality, make them a favourite among travelers. For passive noise reduction, the QZPRO feature soft, leatherette, closed cushions, which create a tight seal around the ear. For active noise-cancelling, the electronics inside each ear cup are designed to monitor outside noise, through specifically mounted microphones in each ear cup, and introduce a sound wave that is 180 degrees out of phase with the incoming signal. These headphones create a peaceful listening environment.
