Koss PortaPro Stereophones, made by renowned audio company Koss, have been around since 1984, which is a huge testiment to just how well designed and well regarded these headphones are.
The design of these classic headphones is nearly the same today as it was back then, however the internal technology has improved in leaps and bounds. Today the PortaPro still remains the headphone of choice for discerning listeners on the move.
Porta Pro stereophones feature dynamic elements that deliver very rich, deep bass and a remarkably wide frequency response from 15-25,000 Hz to capture every bit of your favorite movie or musical performance. They are constructed from mylar, the elements are extremely rigid, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. 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 subway train with an iPod.
Oh, and one last bit of good news, all PortaPro stereophones are covered by Koss’s lifetime warranty.
