Discover how the WH-1000XM4 headphones blend our most advanced noise canceling with exceptional sound quality and a range of smart features for an unrivaled listening experience. Industry-leading noise cancellation technology1 means you hear every word, note, and tune with incredible clarity, no matter your environment. These noise canceling headphones feature additional microphones that assist in isolating sound for a reduction of even more high and mid frequency sounds. Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise-Canceling Processor QN1. Using a new algorithm, the HD Noise-Canceling Processor QN1 then applies noise-canceling processing in real time to a range of acoustic environments. To maximize noise-canceling performance, the WH-1000XM4 headphones incorporate two technologies: Personal Noise-Canceling Optimizer, designed specifically for you, and Atmospheric Pressure Optimizing, designed specifically for air travel. Adjust ambient sound with the Sony | Headphones Connect app to cancel noise while still allowing essential sounds, like overhead announcements, through when you're listening on the move. 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.
