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.
Quick Attention
Regardless of the level of noise-cancelation, the Quick Attention features lets you quickly hear your environment, whether it's to hear an emergency announcement or have a quick conversation. Simply place your hand over the housing of the right earcup to quiet things down so you can hear.
