Koss Porta Pro KTC, the most sophisticated version of the Porta Pro, features a new technological upgrade which brings listeners closer to the music they love.

Listeners are now able to stay connected, shuffle song and adjust volume with the flick of a switch. The remote will work with non-Apple devices, but only with single button functionality.

Koss Porta Pro KTC features the standard setting sound performance the original Porta Pro established over 25 years ago. Designed for those with refined musical taste, the lightweight Koss Porta Pro KTC does not sacrifice practical functionality for great sound.

We Say

A truly excellent headphone for when you want some kick from your music. Bass response is prominent and solid and midrange/treble frequencies have good levels of detail and a musical presentation.
The open design means you won’t get much isolation so leakage could be a problem if you’re cranking your music in the library.
The lightweight build is comfortable and durable and folds down into a neat package for transport/storage.
