Sony WH-1000XM4 Over-Ear Headphones - Black
Product code: WH1000XM4B

Headband style High-Resolution Audio headphones with industry-leading noise cancellation, Adaptive Sound Control, and Speak-to-Chat mode.

Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise Cancelling Processor QN1. Using a new algorithm, the HD Noise Cancelling Processor QN1 then applies noise cancelling 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. 

The WH-1000XM4 headphones incorporate two technologies to maximise noise cancelling performance. Unique Atmospheric Pressure Optimising delivers optimal sound at high altitude while Personal Noise Cancellation Optimiser analyses unique sonic characteristics caused by head size, glasses, and hair, then tailors sound to you. Whether you’re flying long-haul or relaxing in a café, the WH-1000XM4 headphones deliver Sony's best ever noise cancelling performance, keeping out even more high and mid frequency sounds.

Adjust ambient sound with the Sony | Headphones Connect app to cancel noise while still allowing through essential sounds, like transport announcements, when you’re listening on the move. 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 your headphones and advanced audio signal processing to recognise and react to your voice. And once your chat is over, your music starts playing again automatically. Need to quickly hear voices or sounds around you? Just place your hand over the housing to instantly turn your music volume down and let ambient sound in.

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.

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.
