Hello: First time poster, long time visitor to the head-fi site. I would classify myself as an beginner to intermediate audiophile getting the hang of the terminology and learning to be more crtical. Wish I got to you before I drank the Cnet Kool Aid and bought a Klipsch S4 but I don't have problems with it. Good as a beat em up walking around head phone. Anyhow, I was studying the threads extensively on this site and have narrowed my choice for my next IEM to the ones above which all have similar price points. The threads have been extremely helpful, but I wanted to get final impressions before I make my move. I am leaning towards the VSonic due to its better build quality and clarity which does not overemphasize any frequency. That would rule out the Fischer and REO that I was initially looking at. My source is a Cowon J3 and Clip+ Rockboxed. I do have an Electric Avenues Amp. I listen to very wide range of music- electronic ambient like Aphex Twin, Basement Jax, Alternative like Neutral Milk Hotel, Sufjean Stevens , Radiohead, classic rock like Allman Brothers, Beach Boys and Byrds and even a little Hip Hop like Blueprint, Roots, Das Racist, Public Enemy and Beastie Boys. Like I said, very wide tastes that shift on a dime, depending on mood. My music is predominantly in FLAC with some high end Ogg Vorbis, MP3 and WMA, with a smattering of 128kbs WMA before I really became more sound sensitive. I admit I was going to go intially for the UE, however, I heard it has a muddy middle and V-shape sound profile which would not be choice for someone who has very diverse musical tastes. Oh, I do have wide ear canals and I do use the large Klipsch oval tips. I am sure I am missing something else important and I can answer any further questions. Thank you in advance and great job all of you. Your knoweldge has helped me already in making an informed decision.
