Small enough to fit in your pocket, these portable digital noise canceling headphones combine powerful technology with a comfortable earbud design to produce incredible noise reduction with pristine audio. With Sony-exclusive digital signal processing technology, the MDR-NC100D reduces up to 98.2% of ambient airplane, train, or office noise.

Key Features

Digital Noise Canceling Technology

Digital technology provides for optimal noise cancellation with outstanding audio performance. The NC100D reduces up to 98.2% ambient noise when the noise canceling circuit is activated.

Sony Sound

Full, natural sound is reproduced via full digital amplification in concert with a digital equalizer. The MDR-NC100D's large 13.5mm drivers work with digital sound enhancer circuitry to deliver wider frequency response and broad dynamic range.

How it Works

The headphones have an inside microphone on each earpiece that captures the exterior sound waves and works in conjuction with internal circuitry to create an opposite sound wave. Ambient sound is reduced internal by synthesizing with a sound in the opposite phase produced by the noise canceling circuit.

Intelligent Auto-Selection

Noise canceling that is optimized for your environment because 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.

Comfort

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

Long Battery Life

Compact and highly portable, these headphones are ready when you are. One AAA battery can provide up to 22 hours of noise-free listening enjoyment.

Travel Ready

Travel pouch, in-flight adapter, neck-chain style cord with controller (4.9ft), cord adjuster, and a AAA battery included.
