Design Stories: Porta Pro



For over 30 years the acclaimed Koss Porta Pro® has set performance and comfort standards for personal listening worldwide.

Introduction in 1984, Porta Pro® was developed to take personal listening to a whole new level. The Koss Porta Pro® continues to be one of the most popular headphones around the world.

Great sound never goes out of style and Porta® Pro has truly stood the test of time due to it's lightweight open-air design, oxygen free copper voice coils and dynamic elements which delivers rich bass and a remarkably wide frequency response.

The elements used in the Koss Porta Pro® evolved from the Koss Sound Partner (known as the KSP) the world’s first portable Stereophone to collapse into a ball to go anywhere.

The unique design of the KSP transferred the weight and pressure of the headband assembly from the ears to the temporal bone.

The compact design of the Koss Sound Partner allowed engineers to experiment further with an open air, integral design, that could essentially float on the ear, eventually leading to the iconic Porta Pro®.

Introduced on the original Porta Pro® in 1984 was the "Comfort Zone" in which pressure was modulated with a switch that allowed open air performance with enough dynamic coupling to deliver a rock-solid bottom end.

Music lovers couldn’t believe their ears. Koss had managed to deliver an open sound stage with a bass response in something small enough to enjoy anywhere. 

It was the type of performance people around the world couldn't believe possible, until they heard it for themselves. Big sound, in a tiny package….

The Koss Porta Pro® had forever changed the way we all listen to music with true portable personal stereo audio.

Koss would continue to refine the iconic Porta Pro® over the following decades.

Porta Pro® has seen myriad iterations including two Limited Edition versions, an all Black Colorway as well as versions fitted with the latest technologies like Bluetooth® and in-line microphone and remote.

In 2021 Koss create the most versatile Porta Pro® every with the introduction of Koss Utility Series.

Koss Utility Series introduced three new headphones featuring a detachable cord system that gives listeners the freedom and flexibility to connect to virtually any device they own now, or in the future.

For the first time Porta Pro® Utility gave listeners the freedom to connect to Lightning, USB-C and standard 3.5mm headphone ports.

For almost 40 years the iconic Koss Porta Pro® has seen dozens of updates and changes, but one thing that hasn't changed since its introduction in 1984 is it's iconic and acclaimed soundstage.

Whether you’re listening at home or on the go, the Koss Porta Pro® delivers all the excitement of a live performance, no matter which version you choose.
