DescriptionONLY MUSIC. NOTHING ELSE.Sonys intelligent industry-leading noise canceling headphones with premium sound elevate your listening experience with the ability to personalize and control everything you hear.Be at one with your music. 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.Industry-leading noise cancelation technology 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 for a reduction of even more high and mid frequency sounds.The technology that makes it happen. 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.Optimizing noise canceling. 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.Ambient Sound Control. 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.Wireless freedom, 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.Sound you can believe in. 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.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.Smart listening technology to enhance your listening. The WH-1000XM4 headphones use an array of smart technologies to create a seamless, hands-free listening experience. For example, simply start speaking to automatically pause your music in Speak-to-Chat, or enjoy adaptive playback thanks to the proximity sensor and two acceleration sensors that detect whether your headphones are being worn or not.For everyday convenience, just 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 conversationhandy 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.HD Noise-Canceling Processor QN1, Bluetooth Audio SoC and a dual noise sensor let you listen without distractionsPersonal noise canceling optimizer and atmospheric pressure optimizingHigh-quality audio with DSEE Extreme and LDACAdaptive Sound Control automatically adjusts ambient sound settings to suit your location and behaviorWireless freedom with BLUETOOTH® technologyDRIVER UNIT : 1.57 ", dome type (CCAW Voice coil)DSEE EXTREME : YesFREQUENCY RESPONSE : 4 Hz-40,000 HzFREQUENCY RESPONSE (BLUETOOTH® COMMUNICATION) : 20 Hz20,000 Hz (44.1 kHz Sampling)/20 Hz40,000 Hz (LDAC 96 kHz Sampling, 990 kbps)FREQUENCY RESPONSE (ACTIVE OPERATION) : 4 Hz-40,000 HzPASSIVE OPERATION : YesNFC : YesCORD LENGTH : Headphone cable (approx. 3.94 ft, OFC strands, gold-plated stereo mini plug)
