Sony MDR-NC100D User manual

Small enough to t 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 oce noise.
Digital Noise canceling technology
Digital technology provides for optimal noise cancelation with outstanding audio performance.
Read below to learn more about the digital dierence when it comes to noise canceling
headphones.
High-quality sound
Full, natural sound is reproduced via full digital amplication 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 Articial Intelligence (AI) button the
headphones will automatically select the optimal noise canceling mode (for aircra, train or
oce) based on intelligent analysis of environmental ambient noise.
Passive Listening
Allows audio listening even when the power is turned o. Listening in an already quiet
environment? Save the battery for later. Or should your battery run out mid-ight 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 o the headphones for ight announcements or conversation.
3 Earbud sizes
Proper tting 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 tting earbud sizes allow the large 13.5mm drivers to rest
comfortably in your ear.
Battery
Enjoy up to 22 hours of listening time1 with one AAA battery.
Accessories
Travel pouch, in-ight plug adapter, neck-chain style cord with controller (4.9 ), cord adjuster,
and AAA battery included.
