Hello, I am trying to decide whether my image S4s are counterfeit. I am 80% sure they are, since the Klipsch logo is fading and I bought it on amazon for $60. However in terms of sound quality, I cannot be sure, since I don't have any other decent headphones to compare with. So I tested using the frequency meter on this page: http://www.phys.unsw.edu.au/jw/hearing.html. I played the sounds at different frequencies and found that the sound in my earphones dies down beyond 4KHz and almost inaudible at 8KHz and above. As for the low frequencies, the sound level starts to decrease below 125Hz and I cannot hear anything below 45Hz. Klipsch image s4 specs says frequency response 10Hz-19KHz. It cannot be my ears audible range, since I played the sounds on my macbook pro's internal speakers, and I could hear 8 and 12KHz just fine. So here is my request: Could somebody (with proper verified genuine image S4s) go to this website and verify the frequency response. DO NOT PLAY THE SOUNDS AT HIGH DECIBELS AND PLEASE FOLLOW THE INSTRUCTIONS ON THEIR PAGE. Please let me know if you can hear 8KHz and above frequencies and 30Hz and below without changing the decibel level (most importantly whether the frequency response remains flat beyond these ranges, for mine its not) Additionally, if someone with verified fake S4s could confirm my above findings, that would be helpful too. I would be grateful if anybody could help me out, for it will allow me to decide for sure whether my earphones are fake. Many thanks
