General

Koss PortaPro headphones are great for musicians and multimedia lovers who wear their headphones for hours on end. In order for headphones to be worn comfortably for longer periods of time, ear pads cannot put too much pressure on the head. The lighter the headphones, the better. Finally, the sound reproduction quality has to be top-notch. Koss PortaPro headphones meet all these requirements.

These headphones are the result of a serious amount of technical preparation. You can tell just by looking at the extraordinary, futuristic design. Their functionality, however, has also received a lot of attention. What makes a pair of headphones comfortable to wear and easy to use? The special hinged construction with adjustable pressure and additional pads shows Koss’ dedication to comfort. Their collapsible construction and rugged build enable you to take these headphones anywhere.
