Here are two examples for classic IEM wires.
The first link is for 10pcs pre-tinned 0.3mm litz from SoundLink and the second one is 100pcs pre-tinned litz 0.5mm from another store.
10pcs 0.3mm
100pcs 0.5mm
I have already had these wires, they are rather rigid you have to pay attention to the welding stud of the drivers, personally I prefer to use the estron wire of SoundLink, you can double them by twisting them and it remains very flexible

You are right, they do get rigid after soldering. I use to pre kink them before soldering, so that I wouldn't have to apply any force to the soldering area when putting them in place in the shell. That works for me, but I'll try out your wire suggestion too.

I have read and re-read through MOST of this whole thread. Im still searching for this answer… How do you mark your tubing for proper length? Do you use a sharpie marker? Or something else that wont rub off?
Scale is your friend
Plus you can do any style which suites you
You can even print tubes with flexible resin

Creativity and side thinking

I use to use scale and some BA measurement in pdf for spout lenght from where i calculate my tube lenght
I scratch tube a bit to be visible in direct light bouncing of it

Some use marker, sharpie etc

Some just print the tube

Like, resin print the tube?? Or, like soft silicone print the tube? If its resin printed, the FR would be different than the PVC tubing…. Interesting though.

Hey dhruvmeena ,
at first I want to thank you for the work you put in this thread. After reading it I think the best thing for me would be to follow a design rather than experimenting. In the past I already built an iem in an universal shell with just a RAB driver but as am older now and I think my ears won't change too much, I want to try building a ciem and for that use a more complex driver arrangement. Sadly I didn't find a way to get the Bellsing 6 driver so I choose another design I liked to build, even if it's a little harder. I have a few questions for your MASM Renaissance experimental Design you mentioned a while ago:

It works flawlessly if you make the GK dual spot share same 2mm tube

...

GK
Brown damper near spout
White damper in between
2mm ID/ 20mm length

RAB 32063
No damper
Resonator
2mm ID/16mm length
Zobel

So for the GK I understand correctly that the tube has to be stretched over the two nozzles and the brown damper should sit right at the nozzle and the white dampener is supposed to sit between the end of the tube and the brown damper? And do you remember if the electronic components of the Zobel circuit had the same values as shown here https://www.circuit-diagram.org/circuits/4c8ad023 even though the RAB 32063 is a little different than the RAB 32033? Other than that I think the circuit depicted there is the same.
I hope I don't do anything wrong by asking all those questions here.
Again many thanks go to you for your work and your nice designs.

Moritz

MASM is outdated my friend
try using 38D1XJ and dwfk + swfk setup

but if you really want to make a really nice iem
use MASM 3 pro design
GQ + RAB

Moondrop Blessing 2 has an integrated tube design.

I don't mark mine. I cut them right away on top of a ruler.
And then try to snake them through the canal? Some folks have REALLY narrow ear canals and you're lucky to get two tubes let alone a third. Plus, how would you get it to make a turn to the right or to the left? Seriously interested.

@all I might get large quantities of 38D1X, E50, Quad EST in the coming months, and wanted to offer you guys to get those from me then, as I know the struggle in the beginning. I will be buying 100 pcs each(26 for EST) which will cut the price to a bit above half for everything, including EST. If there's enough interest, I can buy earlier. Shipping from here is quite cheap.

Would you say Bellsing 6 + Zobel is outdated as well? I'm thinking about just building more Ciems as I have enough fotoplast for a few shells and already bought the parts for the masm renaissance.

I'm thinking about getting 4 of the 38D1X ( would be about 40 to 50 euros, right?)
