According to Sony, the new NC500D headphones incorporate digital technology with Artificial Intelligence (AI) which ensures optimum audio quality while improving noise cancellation performance. By going digital, this set of headphones can reduce up to 99.1 percent of ambient noise at 160Hz, which is the peak frequency of a jet engine.

The processor inside the NC500D headphones automatically adapts the cancellation profile to suit the characteristics of ambient noise. In normal use, when the 'Select' button is pressed, the headphones will automatically select from three cancellation modes to suit the surroundings - whether on an aircraft, a bus or train, or in the office.

Alternatively, pressing down and holding the mode switch allows the user to manually select the cancellation profile that is most effective in their environment.

Sony Australia's Product Manager for Personal Audio, Suzanna Gan said, "Sony is continually pushing the boundaries with unique craftsmanship and pioneering technology. Through innovation and development, Sony has been able to improve the noise-cancelling ability, enhance sound quality and heighten the signal to noise ratio. These world-first headphones are perfect for frequent travellers and provide a high-quality audio experience with lightweight comfort."

The headphones has an operation time of up to 15 hours between charges of the supplied lithium ion battery, you can shut out distracting noise for the longest flights or train journeys. For extra convenience, they will also operate using AAA batteries for 10 hours should you not have a charger handy while travelling.

Sony's NC500D digital noise-cancelling headphones will be available in Australia from October 2008 with an RRP of $699.
