    Integrated Processor V1

    Specially developed by Sony our new Integrated Processor V1 takes the noise canceling performance of our acclaimed QN1e chip and goes even further. Improved noise canceling performance and Bluetooth System on Chip technology delivers the industrys highest level of noise canceling yet uses less power.

    High performance dual noise sensor microphones

    Two noise sensing microphones per ear one feed-forward and one feed-back on the surface of the headphones catch more of the ambient sounds of your surroundings whether its in-flight noise city traffic or office chatter.

    New 6mm driver unit

    A newly designed 6mm driver unit featuring a 20% increase in magnet volume gives you improved performance in low frequencies. It also enhances noise canceling by generating a high-precision cancellation signal to the low frequency range.

    Noise Isolation Earbud Tips

    Newly developed Noise Isolation Earbud Tips feature a unique polyurethane foam material. Soft and elastic it maximizes the surface contact area between the earbud tip and the ear canal eliminating gaps to insulate sound and reduce noise. It also improves adhesion to the ear canal for a more stable fit making the WF-1000XM4 headphones easy to wear.

    Minimizing wind noise

    Even on windy days youll stay totally immersed. Automatic Wind Noise Reduction mode detects when its windy and automatically suppresses it.

    Exceptional sound quality

    The WF-1000XM4 now supports High-Resolution Audio Wireless. Thanks to specially designed 6mm drivers they reproduce a dynamic sound despite their small size and the high compliance diaphragm reproduces a rich bass range. The Integrated Processor V1 also enhances sound quality and reduces distortion and enables LDAC codec processing and DSEE Extreme.

    Enjoy High-Resolution Audio without wires

    The WF-1000XM4 now supports High-Resolution Audio Wireless thanks to LDAC our industry-adopted audio coding technology. LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional Bluetooth audio allowing you to enjoy High-Resolution Audio content in exceptional quality as close as possible to that of a dedicated wired connection.

    Real-time restoration of all your compressed files

    Using Edge-AI (Artificial Intelligence) DSEE Extreme (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. Dynamically recognizing instrumentation musical genres and individual elements of each song such as vocals or interludes it restores the high-range sound lost in compression for a richer more complete listening experience.
