Following up on their award winning Clear Harmony noise-canceling headphones from last year, Able Planet announced the Clear Harmony NC200 noise-canceling headphones. The foldable ‘phones feature LINX AUDIO, which does all the noise-canceling business with a frequency response of 20-20,000Hz with sensitivity at 1KHz: 110dB and 116dB. A single AAA battery powers the NC200s and they’re available now from Amazon for $99.
