CES: Sony Debuts The World’s First Digital Noise-Cancelling Earbuds

LAS VEGAS — More on the noise-cancelling front: Sony has taken the trick tech of their award-winning, $400, MDR-NC500D digital noise-cancelling headphones and dropped them into these tiny new buds.
Like its big brother, the MDR-NC300D uses artificial intelligence to sense then adapt to the type of background noise occurring in the user’s environment; Sony claims an impressive 98.7 98.4 percent noise-reduction. Tne control unit also has a switch that adjusts the sound to one of three settings (anyone remember the bright yellow Sony MEGABASS swicthes?): Movie, Bass, or Normal.
While my rather limited experiences with the NC300D’s bigger brother never fails to amaze me whenever I try them on, the jury’s still on the little guys. The noise-cancelling feature didn’t seem as impressive; plus, you have to deal with the unit’s control dongle — which is bigger than some mp3 players out there.
