If You Love Music, Listen to the PROs

As the world's largest musical instrument manufacturer and the leading choice of professionals for studio and concert gear, Yamaha knows better than anyone how to make your music sound its absolute best. Now you can enjoy the Studio Sound experience anywhere you go. PRO Series headphones go beyond just "powerful bass" to authentically reproduce any style of music. From Classic Rock to Hip-Hop, from Latin Jazz to Delta Blues, the PRO Series brings all your music to life. Your collection is waiting.


Powerful, Authentic Sound


Tight, precise, and well-balanced – the 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.

Ultra-comfortable and Built to Last

Built to handle the rigors of everyday use without wearing you down, the PRO 500 features an adjustable, reinforced headband with ample padding textured for a pleasant feel. The band is shaped to apply just the right amount of pressure – snug enough to provide noise isolation, yet light enough for long listening sessions. Its ear cushions are extraordinarily soft and smooth, with a feel so natural you'll never want to take it off.


Fuel-injected Design

Drawing inspiration from the world's finest musical instruments and motorcycles, the PRO Series headphones get your heart racing before you even plug them in. Gorgeous geometry and ultra-clean design curves are matched with premium color and finish materials, and emblazoned boldly with Yamaha's iconic tuning-fork marque, conjuring the power and energy of our high-performance supersport bikes.


Versatile, High-performance Connectivity


The PRO 400 comes with two detachable, tangle-resistant flat cables: one in a 4-foot length with an in-line remote/mic, ideal for most mobile applications, and one in a 10-foot length for use in the home. Both cables are made from a material that is durable and designed to reduce "touch noise" transfer effects. The flat construction keeps the internal cores separated to minimize interference and terminates to a low-profile right-angle connector. A gold-plated 1/4" adapter is included in the box for connecting to professional-grade audio equipment.

Control at Your Fingertips


The 4-foot cable includes an in-line remote/microphone optimized for use with Apple iPod, iPhone and iPad devices. The "+" and "-" buttons control volume for both music and phone calls, while the center button allows you to play/pause music, skip to the next song, skip to the previous song, or answer/end phone calls. The controller buttons provide a tactile click-response, enabling intuitive operation without need for visual reference. For non-Apple devices, control behavior varies due to differences in applications and pin configurations.

Bring it With You…Everywhere

Engineered to move you and keep you moving, the PRO 400 folds into a compact size for traveling. It also comes with a semi-rigid protective carrying case.

5 out of 5 eggsGreat Headphones

Pros: Great sound reproduction! Gives superior sound weather on a home stereo or cell phone. Great that it has detachable cable to switch between phone or mp3 player and home environment.

Cons: A little tight on bottom of ear. Pressure not evenly distributed around ear. Not enough to remove an egg because they will probably break in. I also have a more narrow head i guess but it does pose a problem to my wife who's is even more narrow. Otherwise exactly what I expect from Yamaha.

Other Thoughts: BUY THEM!!!!
