From airplane noise to people’s voices, our WH-1000XM5 wireless headphones with 8 microphones for noise cancellation keep out higher and mid-frequency sounds than ever. And with the new Auto NC Optimizer, noise canceling is automatically optimized based on your wearing conditions and environment. With 8 total microphones, these headphones are our biggest step forward in noise-canceling technology. Ambient sound is captured even more accurately for a dramatic reduction in high-frequency noise. Thanks to the new Auto NC Optimizer, noise canceling performance is always and automatically optimized based on wearing conditions and external environmental factors such as atmospheric pressure. 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 8 microphones to deliver unprecedented noise-canceling quality. A new 30mm precision-engineered driver unit featuring a soft TPU (Thermoplastic Polyurethane) edge enhances noise canceling, especially in low-frequency ranges, helping you enjoy your music precisely without ambient noise. The carbon fiber composite material is lightweight, and the high-rigidity dome improves sound clarity, especially in high-frequency ranges. The light and rigid precision-engineered driver unit improves high-frequency sensitivity for more natural sound quality. Sony's 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.
