My only experience with custom IEMs are the UE 18 Pros. In terms of looks and built, I don't think they can be faulted and mine fit my ears perfectly first time round. However, sonically, I really don't think they deserve the $1,350 price tag, I'd rate my Westone 4, UM3x or Turbine Copper higher. There seem to be a big bump somewhere in the high frequencies, and for the last year or so I've been wondering if maybe they were faulty or there's something wrong with my ears that made them sound that way. Then recently I found some frequency graphs of the UE 18 which confirmed my doubts.
If these graphs are right, there is a big bump around 7-8 k which takes out all the sparks in music and gives a very dull sound in general, kind of like the opposite of the HD 800. I've often wondered if that was done deliberately to minimize ear fatigue for stage performers which they were primary designed for, and if that's true, maybe they should warn potential customers about that before they made the purchase.
Although I've not heard the JH 16, just from looking at the graph above, seems to me they have that similar 6-7 k spike like the HD800, do they sound bright and sibilant?
After my experience with UE 18, think I'd give custom IEMs a miss from now on unless I start doing live performances. Right now I'm quite happy with my Westone 4 and UM3x, especially the W4, which to me is nearly as good as my LCD-2.

I heard the UE18 demo and was not very impressed. It had a clean refined BA sound but lacked that realistic 3D imaging for me. Sounded like an expensive BA, just not that expensive. If you like the W4 that much, well, there are options.
I made a thread on "JHA custom re shell worth it?" And included the question below. I think my question below is relevant to what is being discussed here.
BA transducers are pretty much supplied by the same source for most labs right? So JHA transducer is not better than1964 transducer. If so, why is there so much gap in the price difference? Branding? Also JHA has been selling customs around 1K price point for such a long time. Should the price have been that high?
Oh, I get it now! You're suggesting he should consider getting the EX1000s, right? ;)

Knowles and Sonion are the main sources for almost every company selling BA-transducer based earphones, both custom and universal fit.
Of course! Always nice to make stops along the way. 

Btw, to music's point. It should be appreciated that he's just trying to save some people time and money and reinforce they should make careful and educated decisions. Now back to the 'most overrated headphones' thread.
Nah, nvm....
Well, its their money. So if they have it they can spend it. As easy as that. 

He may be in line for the HF Humanitarian Award 2011. I get his point, but that would have been a much more effective way of saying it. He does mean well and could help out some HFers, that much I will certainly concede. But, he could also dissuade someone from trying out a custom based on fear of failure, though many have enjoyed success.

The Westone 4 is my favorite Universal Fit in-ear monitor--the best I've personally tried (for my tastes and preferences).
Not surprisingly, my custom Westone ES5 is, by a wide margin, the better headphone (to my ears). However, even moving much lower down the custom IEM price continuum, I still prefer even my entry-level Ultimate Ears UE4 Pro to the Westone 4. A custom in-ear monitor done right is a tough thing to top, in my experience, in terms of both sound and comfort. (I currently only own customs by Ultimate Ears, JH Audio and Westone. I have not tried the other custom IEM brands mentioned in this thread.)
In terms of comfort, customs have the advantage of not requiring much (if any) outward pressure on the ear canal walls to get the required seal and isolation, whereas universal-fits do. (When done right, customs achieve seal and isolation by perfectly filling the ears.) So I do personally find customs far easier to wear long-term than any of my universal-fit in-ear monitors (save for the Klipsch Image X10, which, for whatever reason, I find almost as comfortable as my customs).
Obviously, music_4321 and I have very different experiences and opinions on this topic, and I'm not trying to invalidate them, as I'm sure he's shared his opinions and experiences no less accurately than I have in sharing mine.
I can agree with the quality of custom, comfort, etc2. What I feel sorry for is that a lot of young head-fier spend thousand of (probably) their parents money after reading the (sometimes) exaggerated custom threads.
I think you should make a warning thread somewhere for those kids to warn them that their ear are still growing. They really should understand the point of making custom.

I have been on the IEM learning curve, seduced by the hype until I have drawer full. I don't have a lot of will power to ignore stellar reviews or maybe I'm just too curious. So while I don't own examples costing a mortgage payment I've got some damned good ones. That being said, I am more convinced at this stage that it is more important to have a good source and a good player than the "best" IEMs. A $10 Timex keeps the same time as a Rolex. Of course it's all about marketing to a large extent and exclusivity. I enjoy playing musical IEMs (pardon the pun) Each has it's own personality and the game is fun to play. My J3 can make an empty dog food can on a string sound acceptable! Sure there are differences and personal opinion is just that. I listen to music for the pleasure I derive from it. The buds are just the messenger.
I'm not sure about how do they get their money and its not for me to judge. But what I know for sure is that they exist. I put my ES3X on sale in the forum and I got 3 serious reactions, all of them from teenager as young as 16 to 19. Once I knew they are 16-19 I decided not to sell it to them. ES3X is an awesome custom but they run too much risk in making a custom is such a young age. I'm not against custom, I have 2 of them, what I'm against is exaggeration that leads people to exaggerated promises.
If those kids are in a band, I encourage them to make one because that is what custom are for. Custom really help me improving my volume control when I'm playing live, being more sync with the band. If they do have one, chance is that their band is solid already and probably they make money out of playing music. I know some kids are really talented. Protest The Hero was 17 when they started and they are insanely good.

Are there that many kids getting $900+ from their parents to buy headphones? Are they stealing the money? I can tell you, the vast majority of parents are not willingly giving their kids the cash to buy custom headphones, unless they are very rich and money means nothing, or maybe if they are in a band or something, as a gift. If a kid works and saves his or her money and wants customs, my guess is they are pretty sharp and would do their homework before spending that type of scratch.
I really believe teenagers buying customs without knowing what they are doing is a very very small percentage of HF members who are moved, rightly or wrongly (depending on your POV about customs being overrated or not) to buy customs. For those who do that (about to make a bad buying decision), there are places on HF for them to learn about buying customs and all it entails. This thread is now one of them. But that seems to me to be a very narrow aspect of the overall thread theme. Again, adults need to make adult decisions, do their research, etc.
Lots of psychology there. I know that all those things do and can happen but I suspect more often than not, a cigar is just a cigar.
I very much agree that there are plenty that jump the gun here and could have done better for themselves with more personal research and patience.
Don't buy an expensive custom unless you've at least had a chance to hear a universal sample or know for certain that you have the same perspective on things as the fellow who's recommendation got you there.
