Thanks for your review. A few short comments:
JH16 Pros: if for some reason the JH-sockets on your shells do not align perfectly with the connectors--you said the plugs don't go all the way in--have them serviced under warranty. That's not the way it should be and once done, revise the scoring for that aspect appropriately
Reshelled JH13 Pros: No reshelled customs should be used for any kind of objective comparative review. IMHO and after conversations with Jerry Harvey reshelling may allow people to "save" a few hundred bucks but often at a risk of getting a sub optimized product, because of incorrect phase tuning by companies who do this. Unfortunately, customers have no way of knowing the difference without a basis of comparison for an original pair custom-built and tuned for their ears. I have no doubt many of them sound impressive enough--afterall there would not be a market for them if it wasn't the case--what I'm saying, however, is there is a considerable risk involved and a considerable chance what you get isn't quite the real thing. If you want customs, my opinion is to bite the bullet and order one directly from the company who makes them, be it JHA, Westone or whatever. Also, a demo pair with a universal tip does not give you the same level of performance as the real thing. It's a demo, an approximation. Even though the drivers and the crossover is the same, it is very, very hard to position the universal tip exactly in the optimal distance from your eardrums as the custom-shelled equivalent would enable you to do so on a consistent basis. It is one of the reasons why no universal IEM can offer the same level of performance as a properly fitted pair of customs can.
ES5s: I've never owned one of these, but the soft tip is a great idea, especially for vocalists who sing wearing them. I would imaging it would be also more comfortable to wear them in general, although once your soft inner tissue of the ear canal has molded itself around the tip of the hard shell, it should be very comfortable to wear after an adjustment period, again, assuming proper fit.
