Our Verdict

Grado SR80e/SR80

Koss Porta Pro KTC

The Koss Porta Pro KTC are slightly better headphones than the Grado SR80e/SR80. The Grado have a better build quality and a more open sound for critical listening with a larger soundstage than the Koss. The Koss, on the other hand, have a more outdoor-friendly design despite being open thanks to their portable on-ear format and in-line remote if you get the KTC variant. They also deliver more bass than the Grado, which some listeners will prefer, and they are compact enough to carry around on your person without much hassle, unlike the Grado.
