Sony has introduced its brand new headphones which it claims to be the first digital noise-canceling set, cutting out a 99 percent of ambient noise by Sony's calculations. The MDR-NC500D product apparently is the first ever headphones set to use digital technology with "Artificial Intelligence". An internal processor automatically calculates the correct cancellation profile to suit the characteristics of ambient noise.
Pushing the "AI Mode" button in normal usage will make the headphones automatically select between three different cancellation modes to suit the surroundings, but manually selecting is also possible increase the "AI" fails. A monitor switch is also included to temporarily listen to external sounds.
Sony advertises the product as being capable of 15 hours operation between charges.
