Users reviews:
I am not very impressed with the Koss KTX Pro-1. Compared to its 60-ohm siblings (KSC75, UR40, Optimus Pro35A) the KTX Pro-1 is very congested and bass-bloated. Midrange has a cluttered thickness that really lacks clarity. Treble is just as congested, and to a certain degree lacks extension.
Yes it uses the STELLAR Koss titanium diaphragm driver, but for some crazy reason… they chose to use a different density earpad foam than its 60 ohm counterparts. I personally own all the headphones I have mentioned thus far, and I dont consider the difference to be minor or insignificant.
In my opinion, the radio shack optimus Pro35A and KSC75 earclip offer better sound reproduction for the $$$. Both offer a sense of clarity, resolution and treble extension that the KTX Pro-1 lacks.
Just for the heck of it… I swapped earpad foams with my optimus Peo35A and VOILA!! the KTX Pro-1 was transformed into a GREAT sounding headphone… just like the KSC75.
Amazon reviews:
Upon seeking out a proper replacement, I thought why not go with the same brand? Whatever equivalent product they have out now could only have improved over the years, right? But no, I guess it's true what they say, "they don't make 'em like they used to."
I got this pair in January '07. I'm still using them reluctantly today. I guess I can't say they're terrible, but what a drop in quality. My old KOSS were extremely light and comfortable and fit well. This new set really starts to hurt my earlobes after 20 minutes or so. The sound is pretty muddy; especially the bass which is needlessly overdriven, making most songs just sound unbalanced. They just feel cheap on the whole.
