Hi all, I was a happy user of Klipsch Image S4i for about 4 or even 5 years! Best of in-ear headphones that I ever had, but somehow I have broken the wire and right hand speaker doesn't play anymore... Now I am looking for buying the new one with similar (or better) spec to the S4i. I was really impressed from bass and clear sound that S4i gave me, so if there is anything better than this (in the good price off course - I want to spend max 150$). I also consider of buying new S4i again! that's why I want to ask you guys what is the real difference between Klipsch Image S4i & Klipsch Reference S4i or Klipsch Image S5i? Is there any difference at all? Thanks for your help in advance Cheers
