Sony WH1000XM4 Noise Canceling Wireless Headphones with Alexa Voice Control, Up to 30 Hours Battery Life, Black

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. Optimising Noise Cancelling To maximise noise cancelling performance, the WH-1000XM4 headphones incorporate two technologies: Personal Noise Cancelling Optimiser, designed specifically for you, and Atmospheric Pressure Optimising, designed specifically for air travel. Multipoint Connection For total convenience, WH-1000XM4 headphones can be paired with two Bluetooth devices at the same time. So when a call comes in, your headphones know which device is ringing and connect to the right one automatically. You’ll also be able to quickly, smoothly switch your headphones to either of the two devices at the touch of a button.9 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.3 All day power and quick charging With a huge 30 hours of battery life you’ll have enough power even for long trips. And if you need to top up in a hurry, you can get 5 hours’ worth of charge after just 10 minutes with the optional AC adapter.6 Clearer hands-free calling Conversation flows freely with easy, hands-free calling. Leave your phone where it is, just speak with a double tap. Thanks to Precise Voice Pickup Technology, which combines five built-in microphones with advanced audio signal processing, WH-1000XM4 delivers clearer voice quality to the other person on the phone.
