If I were in your shoes though, I would also go for silicone filling, it makes them more durable and isolation improves quite vastly.

 

Thank you, I will probably take the risk and go with the silicone filling. If it has any negative effects I will post in this thread so that others are aware.

But I thought it would also affect the sound. Am I correct and what could be the possible effects? I asked the company, but they gave me a very vague response. I would like the extra isolation, but not if it will affect the sound in a negative way. Thank you in advance for any opinions.

If the shell is filled with silicone you get response same as fully silicone monitor (measured and tested, not just a theory) If you compare hollow acrylic and acrylic filled with silicone you get completely different responses on CSD graphs as silicone is damping rining of a driver, which restults in warmer more "organic", as many call it, sound.

Also it would be good if you were aware if there are any vented drivers in IEMs you want to reshell. If you put vented driver in the full silicone shell it basically becomes non-vented reducing sub-bass quantity and extension.

I was thinking exactly the same thing, but you beat me to it! :tongue:

Thank you that has made me more cautious! I don't think any of the drivers are vented but I will check.

 

I guess I have another question then. Would there be the same effect if the shells were filled with acrylic instead of silicone?  Is it the material that matters or is it just the effect of filling the shells? The company I am planning to use don't offer acrylic filler but I'm curious as I know FitEar use that technique. I have demoed the FitEar MH334 and didn't find it especially warm.

Well looks like my knowledge on this topic was pretty bad. Thank you Peter for correcting me and informing us, still being awesome I see :beerchug:

I've never tested that, so I cannot answer.

Hello, I just received a new set of acrylic custom earphones and I have a question about the fit. I have no problems putting in my new earphones. In fact, I am surprised how easily they go in and can be removed. My worry is they are perhaps too loose fitting. For example, if I am walking down the street and I open my jaw slightly, the noise from traffic becomes noticeably louder.  The earphones don’t pop out, but there is still some movement.

 

Another thing I have noticed is that if I am lying down on my back the sound becomes muffled when I am listening to music.  If I adjust the position of the nozzles in my ear, I can sometimes get the sound back to “normal”, but often I have to be standing.  I’ve also experienced a bit of popping in my ear canals like when you are on a plane and it ascends and descends.

 

Does it sound like I have a fit problem and if yes any ideas on what it could be?  I am not completely new to custom earphones as I owned a set a few years ago and I don’t remember having these issues. I also did the Sensaphonics seal test and everything seemed fine (although the high tone did sound slightly louder than the bass).

post #4794 of 4800

It sounds to me like you do have a fit problem based on a couple of things you said:

 

1) The CIEMs are going into your ears very easy.

 

2) Small jaw movement is breaking the seal.

 

3) The popping in your ear canals.

 

I'm only guessing but maybe the canals are not wide enough. That would explain why the sound is getting muffled when you are lying down. I've never had 1, 2 and 3 happen to me but I only have ever had one CIEMs. Hopefully one of the experts in this thread can confirm if it is a fit problem but I think you should contact the manufacturer.

post #4795 of 4800

I agree with drakhen, above, and I would add that I suspect that the area around the 2nd bend of your ear canal may not have been moulded accurately (it is impossible for me to know if this is due to poor ear impressions, poor CIEM-making, or a combination of both. Generally, shortcomings in this area tend to be due to poor impressions, but I know of a CIEM-maker in Pennsylvania who has done a poor job of this area of CIEM shells, for several customers, including me).
