Home-Made IEMs

Posted this in the InEarz Custom Remold Owners Thread, but reposting in here as the DIY crowd seem to pretty much be the most knowledgeable folks on the board when it comes to CIEMs and possible building flaws--and the knowledge gleaned here will most certainly apply to my own custom builds.

So I had a pair of TF10s reshelled at the end of last year before InEarz got out of the reshelling biz. They turned out fantastic, and I'm mostly happy with them. Mostly.
The fit was fine for the most part, though after a few months with them I think the ear canals are a bit too long and are pushing against bone. My main issue with them is that when performing, the highs get muffled as my jaw articulates, despite having used a bite block when my impressions were made. Both IEMs suffer from it, though it's more pronounced with the right one. The problem, I *think*, is that instead of being aimed at my eardrum, the sound tube for the tweeter is pointed pretty much into the wall of my ear canal. Were it the low/mid tube I don't think I'd have much of an issue but with the highs, they pretty much need a clear shot at my eardrum, right?

Thinking this is worth asking InEarz to redo them, just wanted to run it by the hive mind here to see if I'm off base.

In my opinion the positioning of the tubes shouldn't be a problem.

Muffling might be cause by increasing pressure or just change of the shape of your ear canal.

Hi all.

I would like to know what Measurement Equipment do you use and what did you pay for it? Most of the information ive found so far is for Company's and the arent telling the price's or some Asian Reseller Stuff where nobody knows if they are talking about a complete set or only some part of it.

Best Regards, Hasturo

Haha,
By the way - my test kit after last update. Startech USB Card, WM61A with DIY amplifier on Nichicon capacitors. Cables hmm.... :heart_eyes:





Tomekk (Cześć! :) ) and hello everyone!
Just finished reading all of almost 500 pages - very impressive. I have made dozen CIEMS pairs already. Now it is time to measure and improve them.
Where I can find the scheme of the DIY amplifier with Nitchicon caps that you have mentioned? What is advantage of using this type of amplifier rather than normal amplifier in audio interface?
And second one - what is the best way to place and connect the WM-61A inside the coupler? Do you have some DIY link to tutorial of measurement kit, especially coupler? These mentioned earlier are with 404 error already.
Dzięki :) !

Hi,

I also started recently and would like to use a wooden faceplate, because I really like the look of the ones you guys already made!

I already searched the thread but I couldn't find a protocol how to make them. I tried to cover a piece of veneer on both sides with Acryl to glue it afterwards onto the shell, but the Acryl didn't really bind to the veneer. Does anybody have any suggestions how to do it properly?

Thanks :)

Hi!
I just place some veneer on glass or other flat surface and carefully cover it with thin layer of resin, then cure (be careful with air bubbles!). Rotate it upside down and repeat. Then use some 1000/2000 water sandpaper just to make sure that both your iem and and veneer with resin are flat and then glue it with resin and spot cure lamp, transparent two-component glue or come cyanoarylate glue, but this one without 'bad' fumes that will makes our iem white inside (didn't tried - I know that Loctite has the good one). After that grind and sand everything together and after all thin layer of transparent lacquer. That technique works good for me. Of course you have to do some good grind and sand work to make faceplates look stunning.
