Koss PortaPro
Stereophone
High Quality Sound Sets Performance Standard for
Portable Listening
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.
