I travel for work every week and these headphones have become completely indispensable. The 4-layer hybrid ANC is phenomenal the moment you press that button, engine roar and cabin noise vanish almost entirely, and that 45dB reduction is no exaggeration. The 120-hour battery is extraordinary; I went almost two full weeks of daily commuting before needing a charge. The 360° spatial audio with head tracking turns movies on the plane into a genuinely cinematic experience. Best travel headphones I’ve ever used, by a considerable margin.
