Bose is one of the pioneers of noise cancelling headphones and began researching the technology in the 1980s. The first consumer Bose acoustic noise cancelling headphone entered the market a few years later. There are also Bose noise cancelling headphones that Bose designed specifically for pilots and consumers working in noisy environments. Though the company first designed noise cancelling headphones for passengers on aircraft, consumers can use Bose headphones anywhere. Slip them on if you just want to cut off background noise; you do not even have to turn on the music. You can also find in-ear models if you prefer them to the larger over-ear headphones. Bose's over-ear noise cancelling headphones, such as the QuietComfort 15, augment active noise cancelling with materials that add passive noise cancelling. Both types are readily available on eBay. Pick up a pair of Bose acoustic noise cancelling headphones today and isolate music from the noise.
