What do you want is the question and not if masm is decent or not

I think OG members can come up with build easily

So, whats your soldering skill and what sort of sound you are after

Do you think I should go for the final 4 build or the Sonion 38D1XJ+Sonion 3300+Knowles ED29689 build if I wanna make a neutral bass boosted iem with slight energy/extra sizzle in upper mids for female vocal music/jpop? Thanks in advance

@LegendaryDuelist sounds like you're on the right track with 29689. One or two of those with a 38d1xj should be a good starting point.

Excellent! Any suggestions for tubing and dampers?

Hi all,

I just got my ear impressions back and went to the McEar site to find the guide of how to cut them but it has been shut down.

I had previously worked off piotrus-g's example photo but its not loading anymore. Can anybody point me towards a guide of what to cut and how to clean them up.

Im sure the youtube tutorial videos are still available. I would check there.

Closest I've built was a hybrid, but go big on the 29689 tube, 1.5mm ID or bigger could work too. 1mm ID on the 38dixj, damp per preference, but shouldn't need much on either, unless you want to heavily damp the 38d1xj for a lower bass shelf. It will be a lot louder than a single 29689. I'd zobel the 29689, add 2-3ohms series resistance (helps fill in the peaks between 2 and 5k) and high pass 200-800hz or something like that. (Edit: this graph I crossed the 29689 higher for more of a V shape and better top end.) Can't comment much on tube length, so far I just use what I can get to fit.

Bondic or other UV glue to attach tubes.

This was with no dampers, ended up using just a screen/mesh type damper.

Just a follow-up, theres quite literally nothing better than air brushing pro3dure L-1. So quick and so uniform.

Thanks for the reply, I would say my soldering skill is above average, I've done DIY proyects before, not iems tho. I wanna build something neutral/balanced but with a slight boost in mids and energy in upper mids, for a focus on female vocal music, decent bass would be a plus. Also, I contacted soundlink and seems like they don't sell the bs6 anymore, only the bs5 10025.

edit: I was reading the thread, any recipes with Sonion 38D1XJ? Neutral with bass boost and decent treble energy for female vocals? I like j

so, there is soldering and there is soldering IEM/ hearing aid components. Honestly, soldering is the simplest part of the project.

here's the latest project I've completed. Pretty satisfied with the response curve. This is a 6 driver config. using SWFK, TWFK and a Sonion 37. The tweeter boost is not so "peaked" when listening. I have to say, the 37 is very nice non-vented low-end dual driver.

Does anyone have any experience using Variable Resistors/Trimpots to control the bass?
The AAW W500 AHMORPH uses one.
Im thinking about trying it out but don't know if im just wasting my time with it. I'd like to know user opinions.

Pics for reference.

 

[Wgibson]

Yeah, you need to measure FR every time you touch it. Combine with switches if possible. But IMO anything you can adjust after physically completing the IEM is absolutely worth it.

Can you describe the project?

Im about to build something similar. JH has a bass boost in-line on the cable for select models. Mine will be in-line as well. They are great for getting sound adjustment when EQ isnt available

Any iem design related jobs someone wanna offer me

I am open to prototyping iem design and assist on crossover

Also, i am kinda back but my brain cannot think innovative enough nowadays

I am getting old (25years old)

Maybe you can help me figure out how companies are wiring up the DIP switches on there iems.
For example, QDC anole V14, Thieaudio, Tansio Mirai to name a few use DIP switches to tune the sound by use of resistors and caps but I can't figure out exactly how they wire it to get sound in all settings.
What am I missing?
Is this diagram correct?

When off, current flows thru a resistor and when on, it's connected parallel to the resistor so it bypasses it.

So this wiring diagram is correct?
I dont see how it would be connected when in the ON position?
None of the contacts are touching so shouldn't it technically turn off the driver?
