Shut out the din in your air cabin or make clear voice calls on your iPhone with the Creative HN-900 noise-canceling headphones. The concealed microphones in the earcups pick up surrounding noises and these are electronically negated, effectively reducing the noise by up to 85%. With the absence of unwanted sound, the finely tuned 40mm Neodymium drivers allow details of your music or entertainment to be revealed. The Creative HN-900's audio cable comes with an in-line microphone for voice communications on your iPhone.
