Lol, no they actually might be a good pairing.
For whatever I can contribute from my limited listening experience, top of the line universal IEMs such as the SE530s, Triple Fi 10s, ER4s, without equalization sound like CHEAP TOYS compared to customs like JH16 Pro. And it really all comes down to passive crossover tuning.
If you equalize you can still save the farm, but let me tell you that being pulling out this kind of clarity and dynamic range throughout the entire frequency spectrum without touching the equalizer, is a feature that no universal IEM I've heard until now has achieved.
I was extremely satisfied with my equalized SE530s, and once I put on the JH16s I almost had a weird feeling like "this sounds different, but I'm not sure it's better different", because I was so used the SE530s that my ears took that as the "reference". Then after a week of listening, I tried the SE530s again. I laughed, took them off, and unplugged them after 30 seconds.
problem is that doesn't necessarily make them better. I bet if you were to wear your 530s for two weeks, you would fall back into that signature, and love it again. I have seen a common thread with my listening, that whatever i listen to the most, my brain adjusts to that signature and most of the time, i begin to like it a lot.
that being said, some are more accurate than others.
my sony ex300s are not accurate at all, but i can't get enough of them, im not sure why. msrp $80 amazon $20
Here's something posted a couple of hours ago by someone who's tried a demo unit of the Unique Melody Merlin (5 Driver Quad Balanced Armature + Dynamic Driver HYBRID). Here's a quote of the last part of the post:
At one stage I was seriously contemplating going down the customs route, either UM or JHs however after reading some nightmares about fit issues and what not (well having to get it remoulded every couple of years) I decided against it. In hindsight, I don't actually see why people would even consider customs (apart from musicians etc). To me IEMs means portability - having to carry around the customs plus dac/amp while commuting etc, I just don't see it as practical nor do I believe one would truly appreciate the music the customs can produce due to environmental distractions. That leaves using custom IEMs in a semi fixed setup (at home or at work), would people not prefer full sized cans?
Just my opinion.

Before you state your opinion, why don't you just go ahead and do some more reading around here? There is no difference between customs and universals in terms of portability. In fact, one is likely to take care of their customs better in portable use than their universals...
But most importantly if you've never owned a custom how do you form these opinions about that one would not be able to appreciate music fully due to environmental distractions? That's just ignorant conjecture.
I use my customs with my J3 and find it to sound excellent. I do use a dac/amp for my netbook but I did the same for universals as well so no difference there. i actually find customs a bit more "portable" than universals since I no longer have the need to bring a bag of tips in case I lose one while I'm not at home.
How is a custom any less portable than a universal IEM? Aren't they essentially the same bar a few centimetres? With respect to amping, sure I'd imagine they would sound better amped, but the same could be said for top end universals. I'm sure they sound great un-amped as well, since most seem to be fairly efficient, at least compared to top end headphones and even high end portable headphones. Honestly, portability should not be a concern with customs. They're about as portable as it gets.
Also, slightly confused about the "environmental distractions" comment. Isn't the whole point of a well moulded custom that they provide the ultimate seal and sublime sound isolation? Sort of their main purpose, even for musicians really. Very strange comment....
While it's true that Shubar makes some wrong assumptions, his post still made some valid points.
I don't about customs, but i have a very strong suspicion multi driver iems are very overated. My only experience is with UE super fi 5 pros. I could see why some might think they like them, but I thought they were just a gimmick. I couldn't stand the bigger dynamic range within my ear.
One thing this site has taught me is to not trust the opinions of people where large amounts of money are involved.
I'll stick with stock ER-4Ps. I did have some custom sleeves made for them once, but they were useless
Could be because you lisrened to a souped up device and not one trying to be accurate. I actually thought the 3 was the best for the money from that entire series but not because ot was a one way. Nothing wrong with ER4s but I wouldn't **** the lot of multi driver units because the one you heard was not to your liking.
