ShearMe, checked out both Koss products you mentioned. I definitely would not want the Porta Pro because of the slider adjustment, possible to have my hair caught in it IMO. As for the KSC 75, I'll keep it an option while checking out the one you just suggested.
EDIT: Ramamataz, I saw that headphones. The 'RIG - Gaming Audio System' headset right? I'll keep that as another option.
