Don't know if I had much or little credibility before my previous post and quite frankly I'm not here to gain any more (or less) of it...BUT my point was that in the specific case of the SM3s I don't think it comes down to personal preference as I'm convinced the sound (mostly) of this IEM is flawed. The other IEMs I mentioned earlier, which I find better SQ-wise than the SM3s, in my view don't have these flaws and, therefore, one person may prefer, for instance, the IE8 over the UM3X or the other way round - different flavours, so to speak. Not the case, I insist, with the SM3, unless you happen to enjoy food that is 'off'.
Everyone has their preferences. To suggest that an IEM is flawed in sound is like suggesting that McDonald's burgers are flawed and that Burger King burgers are better (and not flawed); you may think that, but there are millions that will think the opposite of you. Does that make them right? Not necessarily, but it doesn't make you right either.
By the way, I don't eat either burgers. New York Burger Co. ftw .
