Since its launch in 1984, the Koss Porta Pro has established itself as an icon in the world of headphones. Renowned for its retro, foldable design, light weight and as one of the few open-back portable headphones, the Porta Pro has stood the test of time without losing its popularity. Today, Koss offers a full Porta Pro range, adapted to a variety of needs while retaining the spirit that made this iconic model such a success.
Original Koss Porta Pro
The original model remains the most popular for its excellent value for money. These open-back headphones offer an airy sound characterized by deep, punchy bass. What’s more, with their multi-pivoting ear cups and soft foam ear pads, the Koss Porta Pro are extremely comfortable to wear, even after hours of use. Their practical, foldable headband makes them easy to take with you throughout the day. Long offered only in blue, the Koss Porta Pro are now available in blue or red on Son-Vidéo.com at €44.99.
I bought my first Porta Pro in 1996 and wouldn’t change them for the world: they’re light and comfortable (you quickly forget you’re wearing them), they offer remarkable spatialization with very good bass for their size, and last but not least, they’re affordable, which doesn’t spoil anything!

For the price, a bargain! Solid bass, clear sound, headphones so light you forget you’re wearing them. I gave them to my wife, who, despite the fact that she doesn’t usually wear anything on her head, immediately loved them after trying them out.
