Making waves with digital audio

“Audio accuracy and sound quality have been improved like never before due to the digitalisation of noise cancelling technology in the Sony NC500D headphones.”

Naotaka Tsunoda, in charge of acoustic design

“It’s the world’s first* digitalisation of the noise cancelling function that is finally realised after 15 years of effort.”

Takayuki Mizuuchi, NC-D500 Project Leader

Making light of challenges

“The Sony NC500D headphones are packed full of new materials and parts such as a new audio cord that can be curled in the slider. This leads to it being so lightweight and comfortable.”

Hiroyuki Ishida, in charge of mechanism/mechanism development

Smarter. Quieter. Clearer.

“The noise cancelling performance has been improved compared to analogue noise cancelling performance. By digitalising the filters, only the frequency that really causes acoustic feedback is removed and the remaining frequency is used for the cancel signal.”

Kohei Asada, in charge of development of the DigitalNC system

“One of the characteristics of these headphones is the AI noise cancelling function that optimises the different noise cancelling modes for three different types of noise. “

Naotaka Tsunoda, in charge of acoustic design

Different voices. Same goal.

“The people in-charge were experienced in different fields and thus could exchange alternative views and opinions. This resulted in a creative atmosphere that led to better ideas. It was great to have been part of this project.”

Comfort for every journey

“The Sony NC500D headphones are superior in cancelling of super low pass audio 100 Hz or less. This range of audio is usually felt as vibrations; thus when it is remarkably reduced, you hardly feel exhausted when using it for a long time on the airplane, train or other vehicles.”

Kazuhisa Kito, in charge of electric circuit/hardware

One-of-a-kind

“It’s fair to say that the NC500D is really the integration of Sony’s audio engineering. It is undoubtedly different from existing noise cancelling headphones in both the aspects of performance and innovative spirit.”

Naotaka Tsunoda, in charge of acoustic design
