In my experiences, the pricing of most IEMs are still pretty much "to scale" with what they offer. The unique combination of comfort (especially with the customs), sound quality, miniature size... etc. Rule of thumb is that full size headphones usually deliver more oomph for less money, but people who use IEMs usually have specific use case where they don't want full size headphones. It's hard to make something incredibly small and deliver a full range of sound. Most...
Ultimate Ears posted a video a couple of years ago (the video is dated 2009) showing people how they make each and every custom IEMs. I didn't know this video existed until today, when Logitech re-posted the video to their Twitter account. It's a good in depth look at the various steps involved in making custom IEMs.   http://www.youtube.com/watch?v=JWdwikZoXzA  
  Actually... I do...   I take at least one flight per year back to Taiwan for visiting my family. Being able to watch at least a couple hours of movies makes passing time much easier (I have a really tough time sleeping on these flights, I may get three to four hours of sleep at most). Being able to use in IEM while watching these movies makes them so much more enjoyable. The quality of the sound output is not great, but the isolation of IEM is far better than any other...
  Comfort is in the eye of the beholder, I suppose. I've gone through almost everything in UE, Ety, and Shure's lineup over the years, as well as Klipsch X10i, some V-Moda and a few other cheaper options. I've never found any of them as comfortable as customs. Basically, I don't like any of the materials for any of the tips on the market. Silicone tips irritate me the least but it doesn't fit as well as sponge and comply. Comply tips and sponge tips fits the best, but...
  I had the opportunity to test the demo units for all the UE products, which are essentially their CIEM with a generically shaped shell and the port opening modified to fit standard sleeves. I don't think they were especially tuned for this purpose, and the reps that has the demo unit will always make sure to tell you that it doesn't sound exactly like the final product, but it's close enough for you to have a good idea of what the sound signature is like.   I tried them...
  No doubt, there are other challenges in CIEM that's very different from universal IEMs. However, also keep in mind that CIEM is like a 20-ish year old industry now, these are problems that they've been addressing for years, and they're still continuing to improve and innovate on.   (As a side note, Sensaphonics posted this pic to Twitter, a CIEM they made for NASA... from waaaay back when before they made soft silicone...
It's apt to include the paragraph right before as well:     So his argument is that an universal IEM has a better reference plane... and assuming that universal has a better reference frame, they would be better tuned. I actually think this argument is completely wrong, because it's the opposite that's also true.   While it's true there's no way for us to know the exact ear canal resonance of every user, a CIEM reduces the variance of that "reference plane" far better...
It's quite possible to get an universal version of a CIEM to sound pretty close, but they won't sound exactly the same. They can tune the driver to sound as close as possible to spec at the port, but there are a few basic problems.   First is the design of most CIEMs are also calibrated around having multiple sound tube for the different drivers, and most of them have at least two to three tubes that opens straight into your ear. These type of design ensures separation of...
You know, after re-reading my post and kerrys30's question... I realized I kind of answered kerry30's question in a round-about way and got onto a different topic than the original intent. A part of that is just some thoughts I had circulating in my head, and then I just went off on a slight tangent. I think I did address the second part of the question (getting a custom tip), almost unintentionally.. but for the first part of the question:     It all comes down to the...
There are companies that will take your IEM and make custom shells for them, although I can't recall which company does this off the top of my head. However, every part in the design of an IEM goes towards shaping the sound signature, so there's no guarantee that by simply taking your favorite IEM and put them into a custom shell, you'll get the same exact sound.   It's really not any different than any other audio equipment. If you take a wooden cabinet speaker and put...
