got my Koss Portapros today, also got my parts express headband for my KSC75. I noticed right away comparing the two that the Portapros have better base, but they are more veiled. I like the KSC75 better, but it has a little too much treble. but UREKA! I discovered that if you use the Portapros headband on the KSC75 they actually sound better it reduced the treble and they sound more balanced. wow ugh?
From now on if i want really good portable light mini headphone, buy the KSC75 15$ and the Portapros 25$ and im flying in town. hmm, 35$ for a good light headphone? too much? I haven’t tried the Koss KPH30i 25$ yet, but i’ll get them soon. Maybe they’ll be better?
