I totally agree... It's been a growing trend I think, with Aurisonics, Tralucent, Fitear, Heir Audio, all doing the same thing.
My one experience with customs soured me on the whole process, and I will never go that route again. I bought a $900 custom dynamic driver IEM and while it fits ok, things get pretty uncomfortable over a long listening session having something so fully jammed into your ear... no matter how form-fitting. And the first couple times I tried to put them in when I initially received them, the hard acrylic shells really hurt making the bend into my ears. I wound up not caring for their sound too much to make matters worse, and now since the molding process permanently bonds the dynamic drivers in place I'm stuck since the drivers are ruined if attempting to remove them for re-shelling for a different owner. Wish I'd have known that going in.
But I'm thoroughly enjoying the Fitear TG!334s still, and I like knowing I always put them up for sale if I find something new I like better... but I kind of doubt that will happen.
