Our Verdict

Koss Porta Pro KTC

Koss KSC75

The Koss Porta Pro are a slightly better headphone overall when compared to the Koss KSC75. The Porta Pro have a better-balanced sound and a more comfortable on-ear fit that you can wear for longer than the KSC75. The Porta Pro also have a better more durable design, although not by much. On the upside, the KSC75 are bit more portable and have a slightly more stable design if you plan to use them for sports.
