Uhmmm... errrmmm... wierd.
So this means, in essence, that you folks are adjusting the EQ for every damned song you listen to considering that would be the only true way to do it, on a song by song basis? Wow, and I thought just listening to music was enough. Silly me.
This is always a point of personal objectivity anyway. I might get the ER-4P Etys I've wanted for a long time now and decide that all of you are schmucks because they sound like crap *even though* everyone else says they're the best of the best. Same situation with Shure E5s, or any headphones - hell, that happens with any equipment period. It's always personal preference.
I'm not an audiophile, I don't believe such a creature exists. If you tell yourself you hear something on a regular basis, sure enough, your mind will fullfill your wish. I'm not interested in having a transcendental experience when I listen to music, I just want something to drown out the noise of the real world. Not much more than that. If someone else thinks it sounds like crap, so be it. What matters is how it sounds to each of us.
