I also have 20/20 but I find it easier and safer to do this with a magnifying glass. I don’t see myself soldering SWFK or E50DT0005 without magnifying glass for example

Hi .
Do the E50DT0005 sound better than the SWFK ?

I have not yet compared them directly, but it seems to me that there is more extension and the yield is better.

E50 it's not a replacement of SWFK. E50 first peak rise in 2khz, SWFK 7 and 10khz.

I was meaning as a tweeter with a capacitor ( from 10khz and up ) not as full range. I'm also very curious how will sound. They may outperform the swfk, isn't impossible. For me all sonion drivers sounded better than any knowles .I don’t have them yet, I still waiting my order.

Than you for the link. Sadly, I think my ears are to small for this build

So I'll probably go with the masm 3 pro. Is it still rab 32033 + GQ30783? And how would I add a wbfk to it (The GQ already has one if I recall correctly)?

It depends. One example: If straight out of the box the ED has a better stage and more air than the Sonion 2389 dark and flat I choose Knowles.

that GQ is damped and it effects the wbfk extension
you can add wbfk with same tube as RAB(or make them into one)- there is a zobelception circuit in this thread which adds wbfk in RAB zobel
this might give you far superior high frequency extension

but my suggestion is

start with simple iem which teaches you basics rather than jumping to MASM or RAB-p(well, its a choice, if you only want to have good iem, then its fine... if you want to learn, its better we start making something new)

just tell me, how many drivers you want to use and i will write down the specs down here and what will it do

Yes it depends. Some prefer knowles and some prefer sonion.
The 2389D is my favorite driver. Without this driver I will quit building iems .So much I like it. Of course knowles sound also amazing. Most popular combo is ci + ed . I prefer sonion.

Hello, I am in the process of building my first CIEM. Making the housings is no longer a problem.

Now I have bought and installed Knowles GK31732 drivers.
I have installed a white damper on the tweeter after 7mm and nothing on the woofer. Both tubes are ID 1mm and approx. 13mm long.

The first listening test was very sobering, especially female voices sound bad, as if the singers were standing in a bath, quiet and somehow not clear. What could be the reason?

Unfortunately, I can't measure it yet because the 711 measuring microphone hasn't arrived yet.

Just wait for the 711. I tried tuning before it arriving too, but it doesn't make sense and will just increase your headache! A 711 will show issues right away.

Use single tube 2mm x 15 mm, no damper or gray/white damper in half tube. It should work fine out of the box.

hello, I didn’t have time to play with this config but it seems to me that the white damper is too weak on the 30017.
Use a green and on bass use an orange.
For tubes, try 1.5mm ID on 30017.
I think you’d gain a little more balance.

How about 4 x 38D1X per side ? Placed exactly like the photo below or is to crazy. It looks nice. Lol.
4x 38D1Xs, 2x 2389D, 2x E50DT0005.
Im thinking of building my last iem with BAs and that's it .
This gonna be out of this World. Hahahaha.

Then im gonna build iems only with DDs ( 10mm shell ) and Over ear headphones.

Anyone did this before ?

I think you are right!

I will try it.
