I currently have a pair of UE700's and am thinking of upgrading in the relative future. One question that's sort of caught me is whether to go with a high-end universal-fit IEM or spend about the same, maybe a bit more, for a low-end custom-fit IEM.
For example, the Shure SE535's will run you around $500 and you can get something like the JH Audio JH5 Pro for $400 plus the cost of the molds. That brings the price to about the same.
So what about sound quality? Single high and single low driver in the customs, dual high and single low drivers in the universal-fits. Isolation is supposed to be better in customs as well and I've heard pretty good things about the fit.
What do you guys thing? Sound quality wise, would they be pretty similar? Would one be noticeably better than the other?
Also, as a follow-up, I've heard custom IEMs need to be remolded every so often since your ears never stop growing. However, I'm not sure how often... Is it yearly, every two years? Every ten? Every few months? Also, I'm not sure how much that even costs. I don't mind paying a bit more on that end since the way I see it I'm replacing foam sleeves every few month and those cost $15 for a pack. Yeah, not quite the same price I'm sure but over a few years it can add up and that, in some small way, helps justify it if the sound is better.
