The WH-1000XM3 wireless headphones use a specially developed HD noise-cancelling processor for sophisticated noise suppression. This function is automat­ically adjusted according to what the user does at any given time. In addition, when the quick-attention mode is activated, users can listen to their immediate environment without having to take off the headphones. The overall design of the headphones, in particular the housing design and the earpads, is also tailored to optimum noise suppression.
