So it is better to base on measurements than calculations that are not too much accurate?

build yourself impedance measuring rig, if you can't, just measure. You should quickly get an idea what cap should give you what result.

I feel like it's such a pain to calculate the actual figures for the caps/resistors that it's faster to do it by trial and error haha

Cool! I will try.

That's very true - it is the easier way. But I think, I could be wrong, that the key to build proper earphones is to understand what is actually happening inside your CIEM, including impedance

Would someone mind point me to some good quality MMCX cables? There are loads on Aliexpress, but I'm not sure when decent quality stops and where snake-oil begins...

I would suggest the Effect Audio Ares II, it's one of my favorite and very well built.

There are few for sale:

I started working on a pair of shallow canal in-ears. Wax dip, !

Materials....... Rose Gold Glitter and Pink Fotoplast make for a fun combination!!

I see you are back to Dreve's now

Pink Fotoplast

Dreve produces pink? Or did you paint the Fotoplast? And what dyes is the master using now?

Link is incorrect.

I think that the most popular dyes right now are Tim Holtz Alkohol Ink. Also this is what Shilohsjustice used to use in the past with great results.

I have to mix colors to achieve pink. I will mix a little red and blue Fotoplast to get violet. I’ll fill my mixing cup with clear, add a small amount of red Fotoplast and add a small amount of the violet to get pink.

When I’m doing other colors I have been using UV Curable Printer Ink, and alcohol ink.

With this kind of ink the curing time increases significantly? Are you using the lacquer to make it skin-safe instead of just buffing or this ink is ok to use without lacquer?

The coating protects the shell from small scratches, makes "skin-safe", and gives the surface a smooth shiny look. So the use of laсquer is desirable in any case if we want to get a good product. Just watch the video of UM, UE, or QDC on Youtube.

A couple of words about dyes. I recently did a customization for my friend. He asked for one faceplate of green and the other white translucent.

I used Ranger Alcohol Ink for green and it was very hard to get it to harden. Even if the mixture is completely transparent. I was forced to apply thin layers one by one and cure. But when sanding the surface was like a slice of tree - rings, small steps. Fortunately lacquer well hid these shortcomings.

Quite another story with white. I used Mixol pigments (German guys - it's next to you). First - you need a very small amount of pigment to paint acrylic, even to an opaque form. Second, the material hardens much better. I also applied layer by layer method, but at some point, I realized that it is not necessary. It was possible to polymerize the required amount of material at once. And there were no layers when sanding, it was a whole piece of "plastic".

If I'm not mistaken here already wrote about the difference between chemical dyes and pigments. About how this affects the penetration of UV light. Maybe it matters. In the future, I plan to experiment with black pigment and try to make not only faceplate but also shells. Opaque or translucent.

A couple of pics: Mixol and the end result.

What resin you are using?
