Both the PX100 and the Koss KTXPRO1 seem pretty interesting.

The problem is where the metal band inserts into the plastic.  The tolerances are too big and allow short hair to pass straight through.  Thus they get trapped or pinched when you go to remove the headset and rip the follicles from your dermis.  Not a problem for most of you folk with civilian haircuts I imagine.

Nah, it's still a problem for me sometimes. I keep the ear-clips around.

Sanji, are those "International" cans the same as the parts-express? How do they sound?

Upon inspection, different drivers and pads, actually. Same headband, though.

I don't think the Internationals have the same air that the Parts-Express does, actually. Instead of air, it's been replaced by a scratch-y sound in the right channel every now and then. Similar lack of bass. They remind me of the really old horn speakers in the way that the bass and treble are so rolled off.

The problem I have with the PX100 is when my ears get stuck between the drivers and music starts playing!
