No matter where you go, the silver 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, leaving your hands and mind free from the hassle of changing settings just to hear what you want to hear. Plus, the headphones detect when you're wearing them and start and stop your audio for you.
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. If quick communication is needed, simply speak to chat without audio playing or just cover the right earcup with your hand to monitor the outside world.
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. This is meant to make your high-resolution audio content sound even better when it's played back through the 1.57" drivers with LCP diaphragms (liquid crystal polymer).
Whether you're looking for peace and quiet while working from home or you want an ideal pair of headphones for traveling, Sony crafted the noise-canceling WH-1000XM4 to be both convenient (with support for Alexa, Siri, and Google Assistant) and comfortable, thanks to the soft, pressure-relieving earpads and the lightweight design.
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.
Quick Charge: With just 10 minutes of charging via an AC adapter (not included), you can gain up to 5 hours of battery life
Tap Controls: Intuitive tap and swipe gestures on the outside of the right earcup let you adjust volume, play/pause audio, change tracks, and answer calls
