These wireless headphones deliver industry-best noise-canceling performance in a compact package. Optimizing the noise-canceling function to the user's style, the headphones shut out noise and offer incredible quality without any cables. Ambient Sound mode, meanwhile, lets users listen to their favorite audio noise-free but still catch announcements and key external sounds. Rounding out the travel-friendly design is the folding-earcup structure, which makes it easy to store the headphones in a seat pocket.
