Sony Electronics has revealed a pair of new headphones called the MDR-NC300D. The headphones look more sophisticated than the white-colored earbuds that come with an iPod and they have the ability to cancel noise. The earbuds also have three modes: general mode, airplane mode, and a trains/buses/cars mode. The MDR-NC300D headphones have the ability to cancel about 99% of background noise. All that is needed is one AA battery to keep the headphones running for 20 hours. The cost is ¥40,900.
