Industry-leading noise cancellation Whether you’re flying long-haul or relaxing in a café, the WH-1000XM4 headphones deliver our best ever noise cancelling performance, keeping out even more high and mid frequency sounds. 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 maximize 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. Wireless freedom, premium sound LDAC transmits approximately three times more data (at the maximum transfer rate of 990kbps) 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. Smart listening technology to enhance your listening The WH-1000XM4 headphones use an array of smart technologies to create a seamless, hands-free listening experience. For example, simply start speaking to automatically pause your music in Speak-to-Chat, or enjoy adaptive playback thanks to proximity sensor and two acceleration sensors that detect whether your headphones are being worn or not.
