canceling technology in a comfortable earbud design to produce incredible noise
reduction and pristine quality audio. Sony's exclusive digital signal processing
technology reduces up to 98.4% of ambient noise (at 160Hz) from airplanes, trains, or at
the office.
Noise canceling technology
Noise canceling headphones reduce ambient noise and provide a quieter environment to enhance audio
entertainment. The headphones have a microphone inside each earpiece that works with electronic circuitry to
reduce ambient sound by synthesizing with a sound in opposite phase produced by the noise canceling circuit.

Artificial Intelligence (AI)
Automatically selects the optimal noise canceling mode based on intelligent analysis of environmental ambient
noise.
