Our Verdict
Koss Porta Pro KTC
Audio-Technica ATH-M60x
The Audio Technica ATH-M60x are a much better critical listening on-ear than the Koss Porta Pro KTC. The Audio Technica have a better build quality, a better-balanced sound, and look much more premium and durable than the Koss. They also have replaceable cables and a closed-back design that isolate a little better in noise conditions. On the other hand, because the Koss are open, they deliver a larger soundstage than the Audio Technica. They're also more portable and come with an in-line remote variant that you can use with your phone, unlike the Audio Technica.
