Thanks! Here is a pair that was finished Friday. Just find those beautiful CIEMS are very much like pebbles. Our engineers took this photo!

Hello Rookie Rooster, sorry about the confusion. Here is the official reply from Heir Audio. We offer two types of IEMs: one is the standard one. It comes with the Black Mamba shell and the Burl wood faceplate. For the +, i.e. 3.Ai+, or 4.Ai+, you get to choose one of three type of wood faceplate: Burl wood, Buck Eye Burl and Black Mamba. In addition, you will get a Magnus 1 cable and free engraving logo etc. At special requests, we are also able to make different color shells, such as red, blue or green, or clear. Those are special features and if there is a need, we can fulfill that. Hope this has clarified your confusion.   

Thanks,... :-)

Hey guys just wondering if I were to reshell my 4ai, does it improve any form of sound quality like soundstage? I'm aware that reshelling for a custom gives better isolation and fit and the 4ai has the same components as the 4A(stop me if I'm wrong) Is it worth it? Thanks in advance!

Yes 4. Ai uses the same configurations as 4. A. Turning your IEM into CIEM will add a bit more at low and in general the better isolation and fit, as you said, will definitely maximize the sound capabilities.

The bass driver used in the 4.Ai (4.A) is a non-vented driver.  What this means is that the bass driver comes from the factory, sealed, self contained etc.  (Technically, the driver already is in its own houseing).

 

Thus, changeing the houseing from a non custom shell, to a custom shell, will not impact the output of the bass driver as the acoustic characteristics of the driver are already "pre-set" by the manufacturer. (Knowles)

 

That being said, the PERCIEVED out put may (or may not) change due to better issolation.

 

Better issoloation is even questionable as well, as an acrylic custom shell is "static" it does not shift, change in shape etc etc with the dynamic movement of the ear canal.

 

The ear canal is in motion a great deal of the time. Simply walking, can cause the mandibular joint to move, and this will cause the ear canal to change in shape to some degree.

 

This movement, can lead to a leakage of sound.

 

Currently your IEM has a "dynamic" ear tip (rubber/silicone tip). The tip behaves like a dynamic "cork" to a dynamic orfice (ear canal). (Honestly, that is a great combination for issolation)

 

And if u look at the research closely, you will find that a dynamic "cork" far exceeds the issolation of a static "cork." (acrylic shell)

 

 

 

 

 

The bottom line is....

 

The results of converting your CIEM to an IEM will be unique to you.  Will the results be for the better or for the worse...?

 

Only you can determine that.

Your comments are well taken. When I said the CIEM will provide a bit more lows because of less insertion loss. The issue here is the actual usage of any devices in the ear, CIEM or IEM, earplugs or inserts. For example, form earplugs are considered the best in terms of fitting compared with others, however in a real world, it performs poorly, even less than other stock eartips or plugs.  Have not done any research about how consistent or inconsistent the performance of the use of eartips is in a real world considering a wide range of user habits, different physical manipulation of fingers and a lot of more other variables in place. Therefore, I tend not to use those "lab data" to a real world situation due to the nature of average. The bottom line is that a customized shell is susceptible to less real world changes.

 

Fully agree with you that the most trustworthy judgment of the perception lies in the ears of the user!

That was in depth. I totally respect your comments. So it all goes down to personal preference. The fit of the ciems could either worsen or improve the SQ I heard. Since I've not own any ciems I really need opinions. Thanks!

No problem and guess that is why there are 4.As and 4.Ais, to meet different needs! let us know if you need anything!

I'll definitely watch for it. :popcorn:

I have the w4r and the 4ai and I honestly find the 4ai more detailed... I like both of them for different things I guess.. I got mine when the otter box was the bigger one so they must have been one of the first batches made..one thing I really love about them is how they make drums sound.. They have that slam ya know... I love that.. That's one thing that the w4r lacks is that how they make drums sound... Like drum rolls and stuff... Makes them sound really real... Sorry I'm not too good at describing the terminology lol.. These are definitely one of my favorite iems... Now that the wizard is gone.. I hope they keep up the good work of what he started... Thanks for a great product guys... Cheers :-)
