Thank you for the detailed response! I ordered the KSC75 a few days ago as my first "audiophile headphone," and the Porta Pro seemed like a good alternative because of its headband. Guess I'll stick to the KSC75 instead :)

I've been looking at these two headphones as the best "beginner" audiophile headphones because of the low price. Does anyone know how they differ in sound? From what I've heard so far, the Porta Pros sound relatively warmer.
