Multi-Noise Sensor technology 
 - With four microphones on each earcup, this is our biggest ever step forward in noise canceling. Ambient sound is captured even more accurately for a dramatic reduction in high-frequency noise. Thanks to Auto NC Optimizer, noise canceling performance is always and automatically optimized based on wearing conditions and external environmental factors such as atmospheric pressure. 
 
 Incomparable noise canceling
 - Specially developed by Sony, the Integrated Processor V1 unlocks the full potential of our HD Noise Canceling Processor QN1. This unique combination of technology controls eight microphones to deliver unprecedented noise canceling quality.
 
 Specially designed 30-mm driver unit
 - The specially designed 30mm driver unit featuring a soft edge enhances noise canceling helping you enjoy your music precisely without ambient noise. The carbon fiber composite material realizes light weight and high rigidity dome and improves sound clarity, especially in high frequency ranges.
 
 Superlative sound, engineered to perfection
 - The specially designed 30 mm driver unit with light and rigid dome using carbon fiber composite material improves high frequency sensitivity for more natural sound quality. Sony unique technologies include a premium lead-free solder containing gold for excellent conductivity, Fine Sound Resistor for even power distribution and optimized circuitry for an improved signal-to-noise ratio to ensure clear, consistent sound.
 
 Ultra-clear, noise-free calls
 - With Precise Voice Pickup Technology and advanced audio signal processing, the person on the other end of the call will hear your voice clearly, even when you are in noisy situations. Our noise-reduction algorithm was developed with AI machine learning using more than 500 million voice samples to suppress ambient noise and extract your voice clearly in a wide range of environments.
