Overview: The Yamaha PRO 400 headphones have an
over-the-ear design to isolate noise. The folding design lets you collapse them and store them in
the included semi-hard zippered case. They come with two tangle-resistant flat cables:
a 4' cable with an in-line remote and microphone so you can control your music
and phone calls with ease, and a 10' cable to use at home or in the studio.
Audio Quality: The PRO 400 headphones deliver superb audio
performance. The newly-developed 50mm Yamaha-proprietary drivers have powerful
neodymium magnets that make them easy to drive with today's portable electronic
devices. You'll get accurate musical reproduction for most any kind of music.
The over-ear design shuts out external sound so you're only hearing the music,
not the outside world.
Comfort: The soft padded ear cushions and adjustable
headband give you hours of listening pleasure without fatigue. The headband is
shaped to apply just the right amount of pressure--not too tight, but snug
enough to isolate much of the exterior noise.
Cables: The PRO 400s come with two cables: one for portable
use and the other for home/studio use. The tangle-resistant flat cables separate the
internal cores to minimize interference. They are coated with a durable rubber-like
material to reduce contact noise. The 4' cable terminates into a right-angled 3.5mm
plug, while the 10' cable has a straight 3.5mm plug. A gold-plated 1/4" adapter is included for listening to your home audio
In-line Remote/Mic: The PRO 400's 4' cable has an in-line remote
control and microphone that is optimized for Apple iPod, iPhone, and iPad. The
3-button remote has "+" and "-" buttons for raising and lowering the volume,
while the center button controls your music (play, pause, skip to next song,
skip to the previous song) and your phone calls (answer call, end call). The
