Sony WH-1000XM4 Wireless Bluetooth Noise Cancelling Over-Ear Headphones with Mic for Travel, Work & Music Listening

The technology that makes it happen

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.
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.
Ambient Sound Control

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.
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.
