Sony touts 'world’s first' digital noise cancellation cans
Whether you’re hoping to envelop your ears in music, or just block out the sound of a screaming baby, Sony's latest cans could be the answer. The electronics giant claims to have released the world’s first pair of digital noise-cancelling headphones.
Sony's digital noise cancelling headphones: a world first?
Analogue noise-cancelling headphones significantly reduce background noise by picking ambient sounds up using microphone near your ear then inverting and playing this soundwave through the cans to cancel the annoyance out.
Four sound modes cut out 99 per cent of ambient noises
Sony’s 'phones do the sound-cancelling digitally in software, which the company claimed makes for more effective noise cancellation over analogue. Analogue noise-cancellation cans are typically 80-90 per cent effective. Sony said its digital version is 99 per cent effective.
Two 40mm drivers are hidden inside the headphones and will cancel noise for about 15 hours from the internal lithium-ion battery. AA batteries can also be slotted in if you run out of juice.
Sony’s MDR-NC500D headphones are available online now for $400 (£200/€250). They will be available in Europe shortly.
