Sony WH-1000XM4 Wireless Industry Leading Noise Canceling Headphone – Black Smartzonekw 20

High-Tech Noise Cancellation

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 cancellation 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.  

Adaptive Sound Control

Adaptive Sound Control is a smart function that can learn to recognize locations you frequently visit, such as your workplace or favorite café, and tailor sound for the ideal listening experience. In addition, it automatically detects what you’re up to—walking, waiting or traveling—then adjusts ambient sound settings to suit the situation.

Optimized Noise Canceling

The WH-1000XM4 headphones incorporate two technologies to maximize noise-canceling performance. Unique Atmospheric Pressure Optimizing delivers optimal sound at high altitude, while Personal Noise Cancellation Optimizer analyzes unique sonic characteristics caused by head size, glasses, and hair, then tailors sound to you.

Wearing Detection

A proximity sensor in the WH-1000XM4 headphones can detect whether you’re wearing them or not, then adapt playback accordingly to help save battery power. Take off your headphones and the music pauses automatically. Put the headphones back on and the music automatically resumes.

Speak-to-Chat Convenience

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 the headphones and advanced audio signal processing to recognize and react to your voice. Once your chat is over, your music starts playing again automatically.
