Specification AgeRangeDescription : Adult AudioDriverSize : 56 millimeters AudioDriverType : dynamic_driver Brand : Sony BulletPoint1 : No matter where you go, the Sony WH-1000XM4 Wireless Noise-Canceling Over-Ear Headphones deliver pristine sound quality while automatically adjusting ambient sound according to your activity and registered locations BulletPoint2 : Noise cancellation is accomplished with Sony's dedicated HD Noise-Canceling QN1 processor and Sense Engine. Sense Engine is designed to automatically adjust the level of ambient sound based on your environment. BulletPoint3 : When it comes to what you do hear, the WH-1000XM4 headphones use DSEE Extreme audio upscaling to perform genre- and instrument-based optimization of the sound, and they support LDAC, AAC, and SBC codecs. When used with a compatible source device, LDAC transmits approximately three times more data, up to 990 kb/s, compared to conventional Bluetooth. BulletPoint4 : 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. BulletPoint5 : 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.
