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.
