Noise Canceling: Reduces unwanted ambient sounds (noise) by using destructive interference. Noise cancellation blocks low-frequency noise, but allows users to hear mid- and high-frequency sounds.
Headphone Type: There are 4 main types of headphones. Enclosed - They enclose the ear entirely with a padded cuff. These are great for eliminating background noise and preserving the integrity of bass frequencies. Ear Buds - Small, bandless and compact, they fit into the entrance of the ear canal. Clip-On - These clip onto the ear and have cushioned speakers. Open Air - Standard headphones with a band.
