1964 Ears Adel IEMs

  Not sure how to answer the how far question since I never measured them but the technician read 64 Ears instructions and remarked that "around the second bend" was deeper than they usually request.  My mouth was clamped down on a piece of spongy plastic.

Did you go to a general audiologist or did you have your impressions done by someone explicitly focused upon the musician and audiophile market? (RockstarEars are an example of a specialist dedicated to musician impressions and sale of appropriate CIEMs)
 
Most of us get our impressions done from audiologists whose main business is hearing aids, etc., with only the occasional customer approaching them for impressions for CIEMs. Broadly-speaking, hearing aids tend not to insert as deeply into the ear as CIEMs (i.e. hearing aids rarely need to penetrate as far as the second bend), so it is quite common for an audiologist to remark that a CIEM impression requirement is deeper than what they are generally accustomed to doing. This is also why CIEM customers need to be polite but firm and explicit in their requirements, rather than allowing a complacent audiologist (who may be very experienced and proficient in doing impressions for hearing aids) to casually (and erroneously) assume that their experience trumps the CIEM manufacturers requirements for impressions to extend just past the second bend of the ear canal. Being firm without causing offence can be a fine line to tread, with some very experienced audiologists, but it can be done

KaminKevKrew and I got our impressions done by Vitaliy. At the time I didn't even know he was the owner of 1964, as I had never heard of them before (bought them solely based on how excellent the sound was from a demo). Though after I figured it out, I understood why my impressions are so darn good, done by the man himself!
 
Also, the 1964 site has some helpful information as well, sorry if this is obvious:

You can also bring a printout from 1964 to your audiologist:

No shipping confirmation for my U12 just yet (Serial #20). I would guess that means it'll be shipped sometime next week.

has anyone tried the adels with a balanced amp?

Hey guys, I was wondering if there would be sales for the Adel series this black friday. Should I wait until then to get the A6 or just get them now?

Just got mine, A12's, my first ever CIEM's. Impressions dropped off to headphones in my ears in 6.5 weeks.

First impressions, the sound is VERY clean, cleanest I've ever heard in my life which is pretty impressive. Isolation is amazing too but that's probably to be expected from a CIEM. One only thing regarding the sound that's bothering me is the higher frequencies are pretty lacking. They're definitely sharp and clean but are noticeably quieter compared the the rest of the spectrum. Feels like even my ATH-m50s do better in that range. Maybe my expectations were too high from reading all the hyped reviews and I was expecting something out-of-this-world perfect, hehe.
 
They sit very comfortably and so far after 2 days of use, no major issues. Only issue I've had is when I laid down on my back in bed to rest and enjoy my collection, after about 1 hour I actually started feeling pretty sick to the point that I almost threw up. Taking headphones out fixed it. Hope it's just me getting used to CIEMs and doesn't happen again...
 
Overall, I'm very satisfied with them. Probably the best audio equipment purchase I've made to date. <3
 
ps: driving them with FiiO E17

Sorry I didn't post the link at 64 Ears.  They are very clear what they want.  They also provide a search page to find audiologists in your area.  I went to one of those.  
 
You don't really need to worry too much because 64Ears inspects every mold and will return one that isn't up to their standards.  I know because I had that happen.  The audiologist spoke to them and re-did the left ear mold to their liking.
 
I was pleased that they were so careful at 64Ears.

Yeah, I didn't mean to make a big thing out of it - was just discussing things casually, and including links for the less-experienced CIEM purchasers reading the thread.
 
 
BTW, virtually every CIEM maker on the planet will inspect impressions prior to manufacturing a CIEM, but the point is that everyone's time is wasted, if the original impressions are sub-standard, and can get expensive if shipping them back-&-forth internationally, too. So, especially for international customers, it is very important to get decent impressions first time.
 
FWIW, although I've never been a 1964 customer, they are at the top of my wish-list for my next CIEM, when I can afford it (that's why I am subscribed to this thread). Probably a pair of A10s  

In my case waiting was not a problem because I got my molds made while waiting as a backer to the Kickstarter in the pre-release phase.  You are right that it is irritating and time-consuming not to get it right the first time.  Living as I do in Northern Idaho I had to drive 55miles to get to the audiologist in Spokane Valley.  Unfortunately mold imperfections do occur and they are not always as obvious to the audiology tech as they are to the folks who make the cIEMs unless the tech is doing a lot of them.  Both of my first molds looked fine to me--pretty much the same but mirror images.  At the end of the day the important thing is that they got it right.  Fit is fine.  Seal if fine.  Sound is extraordinary.
 
You will love the A10s!

how small is it compare to other ciems?

A12 is VERY small, does not protrude at all from my ears, is flush with the ear.

I had to get my molds done 3 times, rejected twice by 64 audio.  I highly suggest all of you go to someone who has done it before for CIEMs and bring the 64 audio impression sheet. GO THROUGH THE SHEET with your audiologist making sure they know you want beyond the second bend, and to fill in all the areas outside the actual ear hole completely up to the very top and bottom of the ear.  1964 ears recommends against tamping down, but I think a very slight tamping down is good if done immedately after filling the ear.  Make sure the audiologist uses the correct viscosity material.  Learn what a correct impression looks like and inspect yourself for defects and incompleteness Before you leave.

Now that's a bad experience.  Sounds like you went to someone who wasn't very experienced or not very good.  I don't know how 64 Ears compiles their list of audiologists but I would start with that and look for one who had done this many times before.  Mine had done it a lot for many brands and still got a reject.  They were a little surprised because they said that they had never had a reject.  They were also very careful about using the recommended material.  Make sure your audiologist does too.

The following post is not a rule - it's just my personal opinion - nothing more!:

I agree, but only (IMO) in the region of the crus of the the helix, which can be seen in this image:
 

 
I only say this because I have personally experienced impressions being deficient in this area, because audiologists are not familiar with it being important (hearing aids often do not occupy this portion of the helix, because they are trying to be more discreet). I often see voids/deficiencies in people's impressions, in this region, although if they are only tiny voids, then the CIEM company can 'fill' the area before producing the CIEM shells.  NB: in the above image, the impressions are good, with no deficiencies in any regions that matter.
