I am in agreement with the comments that the KSC75 is the forgotten giant killer, one which receives little recognition for its high-end performance, a diamond in the rough of the low-end headphone market. Let us understand: This headphone has its own problems as all do with its little ills and sins in sound and build that leave it ever-so-slightly off from perfection than the likes of some of the titans in the much higher price ranges. But because such comparisons as these are made with this pint-sized, pocket-change headphone, it only goes to show the fame and acclaim it deserves.
What it does right is offer a soundstage, or the illusion of the sound coming outside of the ear cups with the instruments and performers distanced from a few inches to a few feet from you. This is outstanding in and of itself as most headphones do not have a soundstage or very little of one until you reach the $100 price point. Of course, it is not as detailed and resolving as a top of the line Beyerdynamic or as smooth and intoxicating as the best of the best Sennheiser, but it still offers sufficient soul in the treble, enough energy in the midrange, and adequate atmosphere in the bass. In some ways, it does better than these by not going at lengths to specialize in any particular sound or range which makes it all the more versatile and perhaps a little more welcome listen. It even scales with your source and amplifier which is something I did not expect from something using ordinary diaphragms and a rather lackluster cable. I can go as far as to rate them above the Sennheiser HD201, Sennheiser HD555, Beyerdynamic DT770, AKG K550, Koss Portapro and many others for these very reasons which is impressive to say the least. (On a side note, I still love my Beyerdynamic DT990 Pro hands-down over any headphone I have listened to bar none, with even the AKG Q701 finding itself taking backseat with its detailed and resolving midrange to the energy and atmosphere I get with this audiophile treat.)
