I personally prefer the sound of the Koss KSC75s paired with the headband from another cheapo pair of headphones, but for some reason my one pair of Porta Pros outlasted all 3 of my KSC75s (one ear keeps going out, probably just need to replace the cable), so now I'm just using the Porta Pro drivers on the cheapo headband.
The Porta Pro headband clamps too tight for me but the cheapo ones are a great fit and it genuinely feels like I'm wearing nothing on my head. It's amazing for both work and play. Been rocking this setup for at least 5 years now.
