Description
The Koss Porta Pro has been a go-to portable headphone since it first appeared in 1984, and Koss has kept its original design and sound signature intact ever since. It’s still one of the most requested models on koss.com, favored by listeners who care about accurate, detailed sound in a lightweight package.
Inside each earpiece, dynamic drivers with oxygen-free copper voice coils handle signal transmission cleanly, reducing mechanical distortion while reproducing a wide frequency range. That means punchy, well-defined bass alongside clarity in the mids and highs, whether you’re listening to music or watching a film.
The foam ear cushions sit gently on the ear rather than sealing it off, giving you an open sound that lets ambient noise through — handy for staying aware of your surroundings. Adjustable temporal pads let you fine-tune headband pressure for extended comfortable wear.
- Frequency Response: 15-25,000 Hz

Koss backs the Porta Pro with a Limited Lifetime Warranty, a rare guarantee in the headphone world, reflecting the durability that’s kept this design in production for decades.
