I must say I'm impressed with the super quick shipping, I just received mine in the mail this morning. Haven't had a chance to use them as I'm at work, but will post back with my thoughts. Very excited to have them.
imtiaz3had a chance to use these more since i received them. All I can say it wow! I'm no big audiohile or anything, but as a musician I think this makes my metal music sound fabulous. Everything punches through, bass is good, not too much which I like. It's very tight actually and not boomy. What I really like is it makes the music sound big. Other IEMs I've used sounded good, but I find these have presence.
