Our Verdict

Koss Porta Pro KTC

Koss Porta Pro Wireless

The Koss Porta Pro Wireless are a wireless variant of the regular Koss Porta Pro with a similar performance overall. The wireless variant of the Porta Pro are a bit more practical for everyday use. They also have a bit more range so you can leave your device on a table and still listen to your audio. The wired Porta Pro, on the other hand, have zero latency when watching videos. They also do not have a battery since they are completely passive, so you will never be without music.
