| First introduced in 1984, this high quality portable stereophone set
performance and comfort standards for personal listening worldwide. Over
the years, much to the delight of devout Porta Pro enthusiasts, we've
preserved the original design and performance that made the Porta Pro
a portable music icon. Today the Porta Pro remains the headphone of choice
for the discriminating listener. Designed for those with refined musical
acuity, the Porta Pro continues to be the most requested headphone at
koss.com.
The Porta Pro features dynamic elements that deliver exceptionally rich,
deep bass and a remarkably wide frequency response from 15-25,000 Hz to
capture every nuance in your favorite movie or musical performance. Constructed
from mylar, the elements are extremely rigid, minimizing mechanical distortion
and ensuring exceedingly accurate sound reproduction. Neodymium iron boron
rare earth magnet structures enable the Porta Pro to deliver greater volume
so you can hear every note, even when competing against the sounds of
a commuter train with a low-voltage MP3 or disc player. Oxygen free copper
voice coils improve signal transmission and conduction for cleaner, clearer
sound. Foam earcushions provide an open, hear-through sound that lets
you keep in touch with your surroundings perfect to wear while running,
at work, or while traveling.
Whether you're listening at home or on the go, the Porta Pro will bring
the excitement of a live performance to any recording.
