If music is your passion, Yamaha designed the PRO 400 headphones for you. They don’t merely deliver sound to your ears, they create the sensation of being there, in your favorite studio session, at an unforgettable concert, or lost in a universe that only exists in the artist’s mind. Tight, precise, and well-balanced, the Yamaha HPHPRO400WH PRO 400 headphones create a rich, deep soundscape isolated from the outside world and tuned to perfection the way only Yamaha can. They incorporate a newly-developed Yamaha-proprietary driver design, sporting robust 50 mm drivers with neodymium magnets that provide maximum efficiency when used with mobile devices such as smartphones, tablets and other portable music players. The over-ear cup shape offers excellent noise isolation, while premium ear cushion materials insure crisp, clear sound reproduction.
