The Yamaha Pro 400 High-Fidelity Over-Ear Headphones (Black) incorporate a proprietary 50mm driver design with neodymium magnets, providing maximum efficiency when used with mobile devices. Built to handle everyday use, the Pro 400 headphones feature a reinforced headband with ample padding. The band is snug enough to provide noise isolation, yet light enough for long listening sessions. Its soft earpads offer excellent acoustic properties. The Pro 400 headphones can fold into a compact size for traveling.
The Pro 400 headphones come with two detachable, tangle-resistant flat cables: a 4' length with an in-line remote/mic and a 10' length. The Pro 400's cable includes an in-line remote/mic optimized for use with iOS devices. It can control volume for both music and phone calls, play/pause music, skip back and forth and answer/end phone calls.
