yes, I had to use blue tack for the finished units.

I had some thin rosewood veneer I used for the faceplates.  The shells are made of UV adhesive I got on ebay (Kafuter).  Measurements are below.  Fairly flat.      

My latest iteration. After at least five tries, I think I hit the best sound yet. I can honestly say this is the first time I feel my diy customs really sound better than my universals. I used a four driver setup. I never believed anything more than three drivers would make a difference, but I'm...

Two words, poster tack. Works great.

I just did this.  I used silicone from Smooth On.  I got a two part clear silicone kit.  For my mold, I follow the same process as an acrylic. I use krystaloid that I bought from lightning enterprises for my mold material.  I then make a hole in the mold where I expect to put my sound tube.  I...

I've been using the guts from an apple ADDIEM.  This is some kind of modified knowles GQ driver and looks like a WBFK/ED combo.  This unit is great for silicone as I get a two way design with a single tube.  In my acrylic shells I have more space and can do a more traditional design with...

Thanks for the tip. I think I'll rip these apart and try making them again. Overall sound is similar to acrylic. Haven't been able to tell much difference, but I fing the isolation and fit much more comfortable.

Not the silicone,but was more worried about other materials in the two part mix.

I've been wanting to make a silicone custom IEM for some time. I finally got around to it after some experimentation. I chose some two part food grade silicone from Smooth On. I plan to use them just a few minutes at a time until I verify I get no allergic reaction.

Thanks, do you coat your ear impressions in wax or build up the impression in any way before casting in the gel?   Thanks

I just want to see a side by side of the ear impression compared to the final IEM from different views.  I'm curious to see how deep from the second bend and if there is any additional build up needed to improve seal.     Thanks

I do have an impression that goes past the second bend. I think i need to try making another resin copy. The current one has too much build up and lost the detail of the second bend. Can anyone send me a picture of their earmold compared to the final IEM. Thanks for the tips.

My first attempt at a three way. CI/ED/WBFK. CI makes a huge improvement on bass. I still have trouble with fit. Mostly mine come out too large and end up hurting after a couple of hours. A made up a resin based copy of my earmold that I built up with layers of nail polish. Either they hurt, or...

 I did this some time ago.  I took apart a plantronics backbeat GO and stuffed it inside the shell.  The backbeat go uses micro usb for charging.  I used a 3.5mm headphone jack instead (you can see that plugged into the side).  Worked well until the battery died on me.  Only lasted about 3...

looks good, can you provide the details of your design?
