this was my first time doing this,, they look ugly so dont expect anything fancy.. the right side did not start off too well and the silicone began curing while I was trying to make corrections

because of the right side mistake, I modified them to fit foam tips on the nozzle by cuttong away the silicone to expose the nozzle.. I get a better isolation this way than with just the foams by the selves... I have another set woth the comply foam tips and these sound and fot better... the current foam that I put on there are some inexpensive foams I saw on amazon that was shown on another thread..

This thread should be closed on health and safety reasons. People please listen to what delladood is saying. Go to a audiologist if you need some ear impressions.

Actually the picture from the owner of this tread seems the impression has gone too deep. You will need otto block to stop it going to ear drum.

I beg all of you... Do not do this.  That putty is not meant to be a complete mold.  It is merely guidelines to pour the acrylic/plastic substance in.  I use it to make my IEM, and it infact, the same exact box is sitting next to me right now. Please refrain from doing so.

 

EDIT: If you do decide to do this(which I do not advise) Do not push deeply the substance deeply into the canal.  If begin to feel pain from the curing process, do not instantly rip the silicone out(or you will have a chance of a lifetime to see your eardrum in your hand.)  Lift up on the ear, and lightly move to see if it is attached to the inner ear.  If it is.  Leave it there, and get your arse to the emergency room.

true,,, I would never go deep into the ear canal.. that is why I just had it deep enough to cover up to the tip of the earphone nozzle and not any deeper...

but yes an ear dam would be best if making a deep impression..

Maybe it's an anatomy thing, but for me is impossible to go deep because the putty is very firm and creates vacuum, so it can't go deep. I could do that many times, no risk at all because is very hard to insert the thing and it doesn't go deep. Very.

well I have done several more impressions... and none of them are deep.. and im actually preferring these over regular/foam tips... even my first set of molds with the foam tips I have stop listening to... the impressions go as deep as the earphones nozzle will go in the mold.. and im still getting a good seal.. bass response is there and im enjoying the fit much more than the many tips I have tried,,, no discomfort whatsoever ...

this isnt something I would recommend though.. go at it at your own risk,, but be smart about it and safe

Even if you don't go too deep you have to make sure to get something skin-safe with ISO or CE.Also you never know if that thing will cure or not at given temperature. So its big risk.

the kind I use is from WESTONE.. and so far all three westone mixtures have cured with no problem including the Radians kit (which was my first mixture)

For those who want to be both cheap & safe: Go to a local audiologist, have him make a set of professional molds. If you ask them for the raw molds (as in whatever they pull out of your ear, without further finishing), it's usually very cheap (I think I payed +/- €10). You can now use these to make a replica of your ear canal (I used plaster as that was all I had). You can now make your own DIY molds from your replica ear canal without risking your ears (and you can see what you are doing much much better). At first I thought there might be a problem with the accuracy of my replica ear canal, and I had to do them over a couple of times, but once I got it right, it worked like a charm.

Too bad I threw all that stuff out, I need to drop by the audiologist and experiment with this a little more....
