I'm quite sure you shouldn't solder the KSE1500 wire onto an MMCX...
Sorry, I mean the normal knowles drivers.

I have to ask since I'm ordering from Aliexpress - what components to you use for the Noble Savant DIY?
I'm going to try to do a MOM first since it is my first attempt.
My soldering skills are ok - I build custom mechanical keyboards (check geekhack.org) since I know everyone here likes to build stuff.
If someone feels MOM is not the first set to try = please comment.
Last question is earphone shells - which ones should I buy? Until I see how much building these interests me I'm not going to try making the molded ones. I don't want to fall all the way into the rabbit hole of custom IEM;s.
ED29689 + 20 ohms resistor
2mm length clearance from spout -> Green Damper -> 3mm length towards the eardrum
(2mm ID tube)
ED30761
1.5mm length clearance from Sound outlet -> Red Damper -> 5.5mm length towards the eardrum
(2mm ID tube)
The tonality shifts due to rising impedance of this design. if paired with bad amp, then you will get honky mids(Not that much annoying, by the way)
low impedance source recommended
different type of resistor affect the sound
different specs of resistor affect the fine tuning
i use precision wire wound
some uses MELF
Precision wire wound is softer and more expansive, due to its slight inductance, which sorta smooths out micropeaks and treble harshness, and quietens things out, but i don't have any scientific claims as such
MELF resistor tends to go more direct and straightforward on signal
plus its better to have deep insertion or custom on noble savant diy
ED29689 can be replaced by Sonion 2354 with air pressure vent closed
that is more ideal as it has less rising impedance all over graph and sorta better extension.
for shell

as you have build mechanical keyboard, you would be knowing where to source out PCB design, its better to have a PCB for design, as it would be easier to debug and will look cleaner and meaner from inside
as for MOM, i dont know which iem design it is
i know MASM(Most amazing set for mom)
difference between MASM and Noble Savant DIYThank you.
Somewhere in my search a few called MASM MOM.
MASM was the one I was referring to.
@Ivan TT, What did you do for your RAF build? Series wiring? Vents open or closed? Dampers? I just wired up a pair of quad RAFs, and I'm debating on if I should vent them or not.

Not yet, but have breadboard set up, 3.5mm in and out, x4 trimpots and ton of caps, just need to find time to experiment...Did you try the Zobel?
Nice....But RAB absolutely shines in 2 driver in series configuration, I call this design “DP” as it goes really deep into the ear canal
RAB has more slam and LF/HF density/extension in 2 driver in series than RAF in 4 driver configuration, at the expense of resolution/details where 4 driver sets are superior.
Should be able to take photos of internal design later on as ordered RABs to do 2 driver RAB set, but here’s some eye candy for you for now:
Its better you buy Knowles RAB because I have on bellsing RAB which stopped working plus RAB are not that expensive.Hello guys. Did anyone use RAB-32257 (Bellsing) and GK-31732 together? Did anyone have experience in reworking the crossover for this stuffing?
