That being said, the cheap Koss headphones do have some issues, which are acceptable for the price, but which stop them from being S-tier, namely the poor bass extension and the strange behavior at 4-5 kHz which depends on the pads. Just look at the FR charts and you'll see - check oratory1990. ServiceServices Meze Elite/HD600/HD58X | Stax GOD
After the HD580 and owning Grados for awhile now, I can safely say that the Portapros don't leak _that_ much. You'll be able to hear things around you, and if you don't listen very loud, it's not going to be a problem. For < $40, you can't buy anything better for your money other than KSC-35's.

aj95_10 Koss ksc75/Porta pros/Blon bl-03 • Additional comment actions i have the porta pros and the ksc75, i prefer the ksc75 way more, the porta pros sounds too "muddy" .
I modified my Porta Pros many years ago and use HD25 velour pads on them. I don't have any of the problems you mention in the mid range. Bass can still be a little muddy. I very much prefer the tonality and bass of the CAL!, so I rarely use my Porta Pros at home. They are for use on the go only.
