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.
