Features

Industry-leading Digital Noise Cancellation

Industry-leading noise cancellation technology1 means you hear every word, note, and tune with
incredible clarity, no matter your environment. These noise canceling headphones feature
additional microphones that assist in isolating sound while talking on the phone, resulting in
improved phone call quality and the reduction of even more high and mid frequency sounds.

Engineering better 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.

Optimizing noise cancelling

The WH-1000XM4 over ear headphones incorporate two technologies to maximize noise
cancelling performance. Unique Atmospheric Pressure Optimizing delivers optimal sound at high
altitude while Personal Noise Cancellation Optimizer 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.

Proprietary technology for premium sound

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. Powered by
DSEE Extreme technology, the 40mm drivers with Liquid Crystal Polymer (LCP) diaphragms are
Hi-Res Audio Compatible, reproducing a full range of frequencies up to 40kHz. QN1 does 32bit
audio signal processing in portions critical for sound quality. Additionally, the digital-to-analog
converter and headphone amplifier integrated into QN1 realizes the best-in-class signal-to-noise
ratio and low distortion for portable devices.

Real-time restoration of all your compressed files

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.

All-day power with quick charging

The WH-1000XM4 headphones are made to last all day and then some, whether you’re focused

on your work or flying around the globe. Up to 30 hours of battery life2 on a single charge keeps
you listening instead of charging. Low on battery? No problem – 10 minutes of charge time gives
you an amazing up to 5 hours of playback.

Quick Attention Mode

These Sony headphones allow you to communicate without taking your headphones off. Place
your hand over the right ear cup to turn the volume down and deactivate noise canceling for
instant conversation.

Touch Control

Change the track, turn the volume up or down, activate your phone’s voice assistant, and take or

make calls by tapping or swiping the panel with your fingertip.

Speak-to-chat

As soon as you speak to someone, Speak-to-Chat automatically stops the music and lets in

ambient sound so you can conduct a conversation – handy if you want to keep your headphones
on, or your hands are full. Based on Precise Voice Pickup Technology, this smart feature uses
five microphones built into your headphones and advanced audio signal processing to recognize
and react to your voice. And once your chat is over, your music starts playing again
automatically.

Clear hands-free calling

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, the WH-1000XM4 wireless headphones
deliver clearer voice quality to the other person on the phone. Precise voice pickup technology
implemented in WH-1000XM4 optimally controls the five microphones built into the headphones
and performs advanced audio signal processing to pickup your voice clearly and precisely for
hands-free calls.

Wearing detection

A proximity sensor in the earcups can detect whether or not you’re wearing your headphones,
pausing your content when you remove your headphones from your head and resuming playback
when you put them back on. Folding the headphones for storage automatically powers the
headphones off.

Multipoint connection

For total convenience, the WH-1000XM4 headphones can be paired with two Bluetooth devices
at the same time.5 So, when a call comes in, your headphones know which device is ringing and
will automatically connect to the right one. You’ll also be able to quickly and smoothly switch your

headphones to either of the two devices at the touch of a button.

Adaptive Sound Control automatically adjusts to your location and behavior

Adaptive Sound Control is a smart function that can learn to recognize locations you frequently
visit, such as your workplace or favorite café, and tailor sound for the ideal listening experience.
In addition, it automatically detects what you’re up to – for example, walking, waiting, or traveling
– then adjusts ambient sound settings to best suit the situation.

Wearing comfort

The WH-1000XM4 wireless headphones blend sophisticated styling with exceptional comfort.
Super-soft, pressure-relieving earpads in foamed urethane evenly distribute pressure and
increase ear/pad contact for a stable fit. And with a lighter-weight design, you’ll barely notice
you’re wearing them.

“Sony | Headphones Connect” App for Android /iOS

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.3 Meanwhile the
Equalizer lets you customize sound levels to suit your music.
