Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise-Canceling Processor QN1. Using a new algorithm, the HD Noise-Canceling Processor QN1 then applies noise-canceling 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.

To maximize noise-canceling performance, the WH-1000XM4 headphones incorporate two technologies: Personal Noise-Canceling Optimizer, designed specifically for you, and Atmospheric Pressure Optimizing, designed specifically for air travel.

Adjust ambient sound with the Sony | Headphones Connect app to cancel noise while still allowing essential sounds, like overhead announcements, through when you're listening on the move.

A built-in analog amplifier integrated in the HD Noise-Canceling Processor QN1 realizes an unmatched signal-to-noise ratio for low distortion and exceptional sound quality for portable devices. Powerful 1.57" 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 40 kHz.

Using Edge-AI (Artificial Intelligence) co-developed with Sony Music Studios Tokyo, 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.

Over time, Adaptive Sound Control learns to recognize locations that you frequently visit, such as your workplace, the gym, or a favorite café, and tailors sound to suit the situation.

Need to quickly hear voices or sounds around you? Just place your hand over the housing to instantly turn your music volume down and let ambient sound in.

Manage your day, just by asking your assistant. Enjoy entertainment, connect with friends, get information, listen to music and notifications, set reminders, and more.

Conversation flows freely with easy, hands-free calling. Leave your phone where it is, just speak with a double tap. Thanks to Precise Voice Pickup Technology, which combines five built-in microphones with advanced audio signal processing, WH-1000XM4 delivers clearer voice quality to the other person on the phone. 

Change the track, turn the volume up or down, and take or make calls just by tapping or swiping the panel.

With the Sony | Headphones Connect app, Ambient Sound Control lets you adjust the volume of background sound and gives you the option to allow voices alone to be heard. Meanwhile the Equalizer lets you customize sound levels to suit your music.

For total convenience, WH-1000XM4 headphones can be paired with two Bluetooth devices at the same time. So when a call comes in, your headphones know which device is ringing and connect to the right one automatically. You'll also be able to quickly, smoothly switch your headphones to either of the two devices at the touch of a button.
