I think this is a bit harsh. From my experience as a 3A customer (and as a 'regular' JH customer) and from reading posts from other 3A customers, whenever we have reached out to JHA, our concerns have been appropriately addressed. I get the feeling that those that have the biggest problem with JHA are not customers.
 
 

No, that isn't what happened at all.
 
There was indeed unbelievable and arrogant behavior, but it wasn't the customers who are responsible for it. No, not at all.

    If one was to go through the trouble of "tunning" each CIEM to a 2 CC coupler (industry standard used to mimic an ear canal) it still would not make much of a difference because every one's ear canal is different, in volume and shape. There is no way this can be compensated for....  

I'm pretty sure that all those tubes have to be different lengths and shapes in each earpiece based on what fits in into the shape of your ear.  With normal customs they have to play around until they get it right.  With the JH3A they can just throw them in however's convenient and fix it in the software.

Right.  Plus FullCircle's point would mean multi BAs should easily reproduce perfect coherence and a DSP would be just a marketing gimmick.  This is not the case.

No point is really, clarify, is it the Shell or tube lengths that need to be calibrated. If one says it is the "shell" that needs to be calibrated, then that really is a marketing gimmick. If one says, "calibrated to make up for any tube length variations" then that would be an accurate statement....
 
assumeing that this is what is really done.

The shell contains all those parts and they're not exactly replaceable, removable, or swappable.  Are you just complaining about semantics?

If they did they would say how about that...no hiss!
 
Seriously. I have good ears and am able to hear hiss.
 
I just listened again and dead quiet.
 
I have better things to do than create a controversy nor stir up any conspirators ( I know what you are thinking! )
 
I take no offense.
 
I will now listen to the Call's "Let The day Begin" in your honor.
 
Here's to all the audiophiles who seek audio nirvana - here's to you my little loves with
blessings from above - let the day begin!  (lyrics mine)

It still makes no sense that you hear no hiss when everyone else with the same recent programming hears it. There is no difference in our amps and clearly you have not received any revised firmware which differs from ours as it has yet to be released. I would love if someone could listen to yours.

I have been following this thread quite closely, as I'm about to pull the trigger on a set of JH16's and have been umming and arring about the JH-3A also. I think if this noise floor issue clears up, and if RYDMOTO's unit is anything to go by, it seems at the very least that it's possible it will. Then I'll be joining the list shortly, will probably wait to hear from the next back of recipients to see if the issue is resolved.
 
I currently have UM's Miracle, I know it's probably a long shot, but anyone who has heard the JH16+JH-3A also heard the miracle and able to compare?
 
Also, anyone know how many pre-orders there are waiting?

they will still tune them by hand as much as possible, at least thats what they said at CJ

Hmm.  I didn't ask Jerry about that at the time.  I figured it was so cheap because they planning on saving on labor as compared to a normal JH16.

yeah, i believe that jerry holds a patent for using the tube lengths to tune for best phase response. which is why th3 16 is so much harder to tune than the 13, since its got 3 tubes instead of 2

 

[FullCircle]

I don't think that patent could hold much water due to the fact that changeing tube diameters for tunning hearing aids and other acoustical devices has been around for over 50 years.

im pretty sure his was jsut for phase response...but then again it was just something i thought that id heard, i could be wrong

see the third patent down on ClieOS's list, thats the one i was talking about

 

[FullCircle]

acually I think you are right to some extent, "UE" & I do not know if Jerry was with them of not at the time, applied for a patent for tube diameters for tunning CIEMs, & I think UE also applied for a patent for the use of dampers for tunning CIEMs
 
The problem is, every one of those patents, concept design etc etc, was based upon technologies, research etc etc taken from the hearing aid industry. Hearing aids are also acoustical devices, just as CIEMs are, hearing aids also have "direct audio input" just as Custom IEMs and non custom IEMs do.   Do you really think Jerry created a "damper" in the first place?
 
I have yet to see one CIEM or IEM company taken to court over patents regarding dampers and tubes....  and I would guess that is because, they know they would lose if you can prove that the technology is not new, and has been in use long before the patent was granted.
 
You can get a patent on essentially anything....  that is the nature of lawyers....  trouble is, is the patent worth the paper that it is written on?
