Sony WH1000XM4/B Noise Cancelling Wireless Headphones with Energy Core Max Power Bank

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 cancellation 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. WH-1000XM4 headphones blend sophisticated style with exceptional comfort. Super-soft, pressure-relieving ear pads 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.

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 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.

Adaptive Sound Control automatically adjusts to whatever you do
Adaptive Sound Control is a smart function that senses where you are and what you're doing, then adjusts ambient sound settings for the ideal listening experience.

  Lose yourself in your journey, with no background noise to interrupt your favorite tracks.
• Walking
  Be aware of everything around you, from street to office, while still enjoying music.
• Waiting

Learns your favorite locations
Over time, Adaptive Sound Control learns to recognize locations that you frequently visit, such as your workplace, the gym, or a favorite café, and tailors sound to suit the situation.

Headphones that react to you
Proximity sensor and two acceleration sensors in your headphones can detect whether you're wearing them or not, then adapt playback accordingly to help save battery power.
