Hello. I bought my pair of s4's on amazon from Crawford's Superstore almost a year ago. They seem decent, no serious fading, they came in what looked like a legitimate blue box, 3 pairs of tips, including the ones on the earbuds themselves.
They came with a case that... Doesn't seem to have fared well, to say the least. I can send pics if you like. It seems like the finish rubbed off fairly quickly...
The earbuds themselves: On the left, the klipsch name looks almost untouched. On the right, it is faded, but only parts of the "psch". I can see scratches along both, but like I said, no fading on the left.
The connections where the wires go into the buds seem to be peeling. I'll post pics of this also, when I get the chance.
There is a straight plug, but the gold almost seems to be fading.
As for sound, I am a bit of a basswhore, but the balance doesn't seem off at all. Volume and EQ is equal in both buds.
Do I (More than likely, of course) Have fakes?
Also worth noting (I can't seem to find it right now...), they came with an instruction paper, with a dB table and warnings and stuff. No ChinEnglish, it seemed well written...
