The WF-1000XM5 headphones reduce ambient noise over a wide range, from low to high frequencies. They feature two proprietary processors that cancel more ambient noise than ever before, a new Dynamic Driver X high- performance driver unit, two feedback microphones and innovative noise- isolating ear tips for a more stable fit. Real-time noise cancelling can be optimised to your environment... for best performance, so you'll hear a big difference, especially on a plane, train or bus.
