Small enough to fit in your pocket, these supremely portable digital noise 

canceling headphones combine powerful technology with a comfortable 

earbud design to produce incredible noise reduction with pristine audio. 

Sony-exclusive digital signal processing technology reduces up to 98.2% of 

ambient airplane, train, or office noise.

Digital Noise canceling technology

Digital technology provides for optimal noise cancelation with outstanding audio performance. 

Read below to learn more about the digital difference when it comes to noise canceling 

headphones.

High-quality sound

Full, natural sound is reproduced via full digital amplification in concert with a digital equalizer. 

Large 13.5mm drivers work with digital sound enhancer circuitry to deliver wider frequency 

response and broad dynamic range.  

Precise Noise Canceling

A key distinction with digital noise canceling is precision. The NC100D reduces up to 98.2% 

ambient noise when the noise canceling circuit is activated.

Intelligent Auto-Selection 

Not all ambient noise is the same. When you press the Artificial Intelligence (AI) button the 

headphones will automatically select the optimal noise canceling mode (for aircraft, train or 

office) based on intelligent analysis of environmental ambient noise. 

Passive Listening

Allows audio listening even when the power is turned off. Listening in an already quiet 

environment? Save the battery for later. Or should your battery run out mid-flight and you not 

have a spare, you’ll still be able to listen without the noise canceling activated. 

Convenient Operation

Easy-to-reach volume and built-in monitor function on the controller allows you to hear 

surrounding sound without taking off the headphones for flight announcements or conversation.

3 Earbud sizes

Proper fitting noise isolation earbuds not only stay in your ear more comfortably and securely; 

they also provide better attenuation of ambient sound. 

Ergonomic Design

Vertical in-ear style housing and proper fitting earbud sizes allow the large 13.5mm drivers to rest 

comfortably in your ear.
