ONLY MUSIC. NOTHING ELSE.
Sony s intelligent industry-leading noise-cancelingheadphones with premium sound elevate your listening experience with theability to personalize and control everything you hear. 
Be at one with your music. Discover how the WH-1000XM4headphones blend our most advanced noise-canceling with exceptional soundquality and a range of smart features for an unrivaled listening experience.
Industry-leading noise cancelation technology means you hearevery word, note, and tune with incredible clarity, no matter your environment.These noise canceling headphones feature additional microphones that assist inisolating sound for a reduction of even more high and mid frequency sounds. 
The technology that makes it happen. Dual noise sensortechnology, featuring two microphones on each earcup, captures ambient noiseand passes the data to the HD Noise-Canceling Processor QN1. Using a newalgorithm, the HD Noise-Canceling Processor QN1 then applies noise-cancelingprocessing in real time to a range of acoustic environments. Working togetherwith a new Bluetooth Audio SoC (System on Chip), it senses and adjusts to musicand noise signals, as well as acoustic characteristics between the driver unitand ears, at over 700 times per second.
Optimizing noise canceling. To maximize noise-cancelingperformance, the WH-1000XM4 headphones incorporate two technologies: PersonalNoise-Canceling Optimizer, designed specifically for you, and AtmosphericPressure Optimizing, designed specifically for air travel.
Ambient Sound Control. Adjust ambient sound with the SonyHeadphones Connect app to cancel noise while still allowing essential sounds,like overhead announcements, through when you're listening on the move.
Wireless freedom, premium sound. LDAC transmitsapproximately three times more data (at the maximum transfer rate of 990 kbps)than conventional BLUETOOTH audio, allowing you to enjoy High-Resolution Audiocontent in exceptional quality, as close as possible to that of a dedicatedwired connection.
Sound you can believe in. A built-in analog amplifierintegrated in the HD Noise-Canceling Processor QN1 realizes an unmatchedsignal-to-noise ratio for low distortion and exceptional sound quality for portabledevices. Powerful 1.57" drivers, with Liquid Crystal Polymer (LCP)diaphragms, make the headphones perfect for handling heavy beats and canreproduce a full range of frequencies up to 40 kHz.
Real-time restoration of all your compressed files. Using Edge-AI(Artificial Intelligence) co-developed with Sony Music Studios Tokyo, DSEEExtreme (Digital Sound Enhancement Engine) upscales compressed digital musicfiles in real time. Dynamically recognizing instrumentation, musical genres,and individual elements of each song, such as vocals or interludes, it restoresthe high-range sound lost in compression for a richer, more complete listeningexperience.
Smart listening technology to enhance your listening. TheWH-1000XM4 headphones use an array of smart technologies to create a seamless,hands-free listening experience. For example, simply start speaking toautomatically pause your music in Speak-to-Chat, or enjoy adaptive playbackthanks to the proximity sensor and two acceleration sensors that detect whetheryour headphones are being worn or not.
For everyday convenience, just Speak-to-Chat. As soon as youspeak to someone, Speak-to-Chat automatically stops the music and lets inambient sound so you can conduct a conversation-handy if you want to keep yourheadphones on, or your hands are full. Based on Precise Voice PickupTechnology, this smart feature uses five microphones built into your headphonesand advanced audio signal processing to recognize and react to your voice. Andonce your chat is over, your music starts playing again automatically.
