HARD TO BELIEVEI have the Yuin PK2 and I never heard the KOSS Ksc75 until a week ago.
Now I want the Koss Ksc75 cos it has more bass, everything is smooth and clean crisp sound.
Surely PK3 can't have better sound quality then the KOSS KSC75?
But the PK3 can't produce bass like the KOSS KSC75...
I'm talking exclusively on sound quality and not their size or comfortability or price range...
