The KSC-35 is discussed quite a bit, IME (although I think it's officially out of production). The Sportapro is not too popular around here for some reason, and the Portapro2 is definitely out of production. Any further questions?

No extension up top, and bottom is plain muddy. So is this the standard "titanium" drivers that Koss are using in many of their lower-end cans these days?

The 75s have the titanium and don't sound good also?
There are other problems with the KTX Pro1 that could be contributing to its poor SQ... namely the terrible quality cable + volume control, and the design of the earcups. Haven't heard the KSC-75 myself.
P.S. the Portapro, Portapro2 and (pretty sure) KSC-35 definitely use the non-titanium drivers.

The drivers with titanium coatings tend to sound brighter (harsher to
some people). The non-coated drivers sound warmer.
You need to carefully read the fine print on the specifications on Koss's
website. The one's with titanum coatings say so.
Most people don't realize this because they don't carefully read the fine print
on Koss's website.
That sir, is one heck of a first post! Thanks for that information. I use 35's for portable and presently at the office until my Ety's are resurrected. The 35's look like crap but sound amazing. They are also bus and subway (and heck sidewalk) safe, particularly in big metros. No one will anticipate a nice audio player with those ugly things hooked to it. I use an iPod Photo, not exactly cheap. Folks must think I'm using some cheap am radio. Heh if only they knew I was getting some of the best portable sound around
Carefull everyone... there are two different Koss 60 ohm drivers:
Clear transparent driver:
KSC35, Original portapro, PortaproII. I think the TD80, TD61 full size cans use this driver as well... But dont quote me on it.
Titanium coated driver:
KSC75/55/50, KTX-Pro1, UR40. I think the sportapro also use this one. I have a Sportapro coming in a day or 2 and will know for certain. There are a couple Radio shack cans that use the Ti driver too.
