Sony WH-1000XM4 Wireless Noise Canceling Over-Ear Headphones (Black)
Discover how the WH-1000XM4 headphones blend our most advanced noise canceling with exceptional sound quality and a range of smart features for an unrivaled listening experience. It features industry-leading noise cancellation technology that 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 Canceling
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.
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
The WH-1000XM4 headphones are made to last all day and then some. Up to 30 hours of battery life on a single charge keeps you listening instead of charging. 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.
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.
