I think I can get really good seal with my Shure 535, the problem is that takes much longer time to get that prefect fit/seal with a universal. It can take me almost half minute to find that perfect fit, while with my Customs I get there in a second. So I don't understand some comments here that they use universals when they need to be able to put the IEM out and in quickly and often. I Think that's what customs are for? I might not be faster then Joe to put my 5-way in (1 sec) but I believe I beat him on the removal as I can do that in less than 2 sec ;) Just unscrew them.
And universals is not as comfortable!
My experience comparing universal fit vs. customized versions is based off the TF10 (I have one of each), the Rooth LS8 (I borrowed a demo), and the UE PRM (tuning set vs. customized set). In all three cases, the ones customized for my ears sound better as far as micro-detail, soundstage space, instrument separation, bass, and some other factors as well. What causes the difference? More contact area of the shell with my ear canal, a better nozzle angle, fewer material changes before the sound exits into the ear canal (the internal material of an IEM is not the same as the universal ear tip), and/or sound tuned for the specific shell configuration? Whatever the reason, there is a difference to my ears.
I can probably take the SE5 out in a second, but I was trying to be conservative ;) I think grabbing it the right way is important and when I haven't used them in a while I have to remember to grab the shell, not twist by the cable.
