Lightweight headphones

  • Great sound for the price
  • Collapsible

  • 1980s styling
  • Sound leakage
  • Awkward headband

The Koss PortaPro headphones were first released in 1984, and have remained virtually unchanged for more than 25 years. But they're a perennial favorite, despite the 1980s aesthetic, thanks to sound quality that is far in excess of what reviewers expect for under $50. The PortaPro are held together by a sliding metal headband that can shift and get caught in hair, but otherwise critics find these fold-away headphones very comfortable. They are open-style, though, so sound can leak in and out. The PortaPro headphones also come with a rudimentary carrying pouch and a 1/4-inch stereo jack adapter, and even have a lifetime warranty. A 25th Anniversary version of the PortaPros was released in 2009 with a nice box, collectible coin and some minor cosmetic differences. For a still-cheaper alternative, reviewers say that Koss's KSC75 headphones (*Est. $15) are a good choice, too, and are a surprisingly strong performer given their price.

Thanks to their ancient (by electronics standards) pedigree, some headphones critics overlook the Koss PortaPro in favor of newer designs. However, we found comprehensive coverage of the PortaPro at CNET, Head-Fi and HeadRoom. And and customers have been praising the PortaPro headphones highly for over 10 years.

The Koss PortaPro headphones get an Editors' Choice award and 4 out of 5 stars at CNET nearly 25 years after their initial release. Justin Yu says that the sound quality and functional design far outweigh the aesthetic considerations of the dated design. However, Yu notes that the metal headband doesn't lock in place and can get caught in hair.

"Whenever people ask for recommendations for a budget pair of portable headphones which provides a large amount of satisfying bass, the Koss PortaPro will always be among the first in the list," he writes.

Like, collects ratings from users of audio products, though their respondents are from a number of countries. Users rate the Koss PortaPro with a 4.4 out of 5 overall score, due mostly to their good value. Sound quality is better in much more expensive models, users note, but not at this price point.
