Wireless Noise Cancelling

Advanced noise cancellation : Whether you’re flying long-haul or relaxing in a café, the WH-1000XM4 headphones deliver our advanced noise cancelling performance, keeping out even more high and mid frequency sounds.
The technology behind the noise cancellation : 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 : The WH-1000XM4 headphones incorporate two technologies to maximise noise cancelling performance.
