Advanced noise cancellation
Whether you’re flying long-haul or relaxing in a café, the WH-1000XM4 headphones deliver our advanced noise cancelling performance, keeping out even more high and mid frequency sounds.
The technology behind the noise cancellation
Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise Cancelling Processor QN1. Using a new algorithm, the HD Noise Cancelling Processor QN1 then applies noise cancelling processing in real time to a range of acoustic environments. Working together with a new Bluetooth Audio SoC (System on Chip), it senses and adjusts to music and noise signals, as well as acoustic characteristics between the driver unit and ears, at over 700 times per second.
Optimising noise cancelling
The WH-1000XM4 headphones incorporate two technologies to maximise noise cancelling performance. Unique Atmospheric Pressure Optimising delivers optimal sound at high altitude1 while Personal Noise Cancellation Optimiser analyses unique sonic characteristics caused by head size, glasses, and hair, then tailors sound to you.
Ambient Sound Control
Adjust ambient sound with the Sony | Headphones Connect app to cancel noise while still allowing through essential sounds, like transport announcements, when you’re listening on the move.
Be smarter with Voice Assistant
Get hands-free help. Just say “OK Google” or “Alexa” to activate your preferred voice assistant. Enjoy entertainment, connect with friends, get information, listen to music and notifications, set reminders, and more. You can even control your headphones’ features like noise cancellation with your voice
Sound you can believe in
A built-in analogue amplifier integrated in the HD Noise Cancelling Processor QN1 realises an unmatched signal-to-noise ratio for low distortion and exceptional sound quality for portable devices. Powerful 40mm drivers, with Liquid Crystal Polymer (LCP) diaphragms, make the headphones perfect for handling heavy beats and can reproduce a full range of frequencies up to 40kHz.
