acrylic vs silicon housing for custom iem? - Page 3

Thread Starter 

Thanks for the reply Larry. I heard from 1964 ears. I want their quad iem but with this one they can only do the tips in silicone, the main housing would be acrylic. I wonder if this would still offer improved comfort and isolation. I guess it would though since the tip would be the part that would be in the ear canal itself. Greetings, Anouk,

hmm consider or not if it's worth the Extra $100 for silicone...

IMHO, silicone is a superior material for this application, no question. It's not even close.

 

Caveat: I'm not familiar with this particular product.

 

As to whether it's worth $100, that's a personal choice. But people pay that much to get an extra driver all the time. In my mind, the gap between acrylic and silicone is obvious and meaningful, while the difference between n and n+1 drivers is a decidely mixed bag.

Hey Jack

Just coming back to the topic, I agree silicone > acrylic overall (the discoloration factor still bugs me tho personally lol rolleyes.gif). I have heard recently there were acrylic housing with silicone ends available (Not 1964 ears). But I have also heard that overtime, the silicone ends will weaken and eventually detach from the acrylic shell.

Please comment on rumor? =_=

This is mechanical engineering 101 -- a two-part system is rarely more structurally sound than unibody construction. Silicone has non-stick properties and doesn't bond well with other substances, so the problem is exacerbated. There is anecdotal evidence that this has been the case with acrylic body/silicone tip designs, but I haven't experienced it personally.

Hey guys, just a quick question.

 

I am looking to get some custom made ear moulds for my Sennheiser IE8. I live in Hong Kong currently and the only company I could find is http://www.hearingtune.com/eng/cust_earmould/earphone.php

 

I am unsure if their silicone moulds are high quality or not. So I asked them and they told me "Our earmoulds are made of soft and hot-cure transparent silicon material. Discoloring and hardening is possible to happen due to oily ear canals and warm body temperature."

 

Does this sound normal to you? I know cold-cure was recommended earlier, just want to see if it is worth getting or not.

 

The total price will be around 130 USD.

 

Thanks in advance!

the soft tips various manufacturers have tried tend not to last as long, although initially they are more comfortable and perhaps seal better. with accurate shaping of acrylic you should get the same quality seal, and they'll last longer. the discoloration of silicone has not bothered me, but after one or two years, you definitely start worrying about longevity of the custom tips...
