Sony WH-1000XM4 Wireless Noise Cancelling Headphones, 30 Hrs Battery Life, Quick Charge & Alexa

Discover how the WH-1000XM4 headphones blend our most advanced noise cancelling with exceptional sound quality and a range of smart features for an unrivalled listening experience. Industry-leading noise cancellation technology means you hear every word, note, and tune with incredible clarity, no matter your environment. These noise cancelling headphones feature additional microphones that assist in isolating sound for a 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 QN1e. Using a new algorithm, the HD Noise-Cancelling Processor QN1e 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. To maximize noise-cancelling performance, the WH-1000XM4 headphones incorporate two technologies: Personal Noise-Cancelling Optimizer, designed specifically for you, and Atmospheric Pressure Optimizing, designed specifically for air travel. 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. 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. A built-in analogy amplifier integrated in the HD Noise-Cancelling Processor QN1 realizes an unmatched signal-to-noise ratio for low distortion and exceptional sound quality for portable devices. Powerful 40 mm 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. 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 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. 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.
