Hullo ! I bought mine about a month ago. At first, I couldn't manage to get the peculiar ear-seal you need in order for them to fully display their potential; none of the included ear tips could get the job done, no matter how I squeeze them in my ears... They just sounded like the cheapest earphones available anywhere. I knew it was hard to get them to sound the way they were supposed to for all the reviews I read about them (and believe me, I read over 50) However, everything changed the moment I changed the ear tips. First, I used the large sized Sennheiser's silicone tips (I got big ears), and though they definitely improve the quality of the sound and achieved a tight seal, I knew they could sound even better. Next, I tried the Skullcandy's large silicone tips (which are somehow softer than the Sennheiser's) and WOW! Finally, the sound I was looking for was there and more. However, even with these ear tips, I still spend some time squeezing them right to get the proper seal. Now, on to the issue at hand: One thing I immediately noticed was the fading of the logo on the right side only after 1 week of use. I went ahead and searched on the web to see if this was a clear sign of them being a fake, but there were no mentions about it, until I came about this thread (by then, the logo on the left side was gone too). If, indeed, the logo on both earphones fade away so fast normally, then I will not be concerned. However, it would be great if a Klipsch representative confirms this. KLIPSCH, are you listening (reading)?!?!
