RP-HC31 and RP-HC55 noise-canceling headphones

Panasonic has another set of earphones primed for introduction to the market this June, the RP-HC31 and RP-HC55 sets, which are both noise-canceling headphones.

The RP-HC31 earphone drivers are 10.7 mm with a frequency response of 8 Hz to 22,000 Hz. The amount of noise-suppression is 15 dB and the news-release page says that the impedance is 20 Ohms, which I suspect is a typo. The noise-canceling function is powered by a single AAA-cell for approximately 27 hours of use time.
