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.

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.

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.

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.3

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.

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.

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.

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.

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.4

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.

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.

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.

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.6

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.

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.

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.

Improved Smart Listening by Adaptive Sound Control now automatically detects not only your activity, but your location as well, adjusting ambient settings to optimize your listening experience. Whether you’re travelling in an airport, walking on a crowded street, or sitting in a quiet area noise canceling levels are automatically balanced. Atmospheric Pressure Optimizing keeps your music sounding great even when traveling at higher altitudes. You can customize them to your preferences with the Sony I Headphones Connect App.3
