First introduced in 1984, the KOSS PortaPro quickly became a standard for portable music lovers at that moment. And till today, with that same old design and sound quality, PortaPro still can satisfy music enthusiasts of all ages all over the world. The unique dark sound signature of PortaPro, with the impressive, strong bass performance, has made itself the most famous KOSS model of all time, and the truely stable music icon. Its unique design makes you enjoy the music comfortably, it feels like you’re using full-sized headphones, but when folded, the PortaPro is just as small as a fist.
“The PortaPro is an age old design, but has held up over the years, despite newer portable cans coming along. Perhaps it is the very age of the design that keeps people coming back to it… The sound is fun. The PortaPros have a nice, punchy sound, and great bass for a small supra-aural set of phones”
