Thanks @furyossa For now I let it burn in some more, and it is improving. I'll keep your advise in case I got the itch to mod it in the future.
Could it be the correct "timbre" and the natural mids that make it easy to listen? As I said, in the MX500 housing it reminds me of a single driver, full-range speaker.

Did you ever post how you bore out the wooden piece? Was it by lathe? Sorry if you've posted here, I've searched but couldn't find a specific mention.
What will be the effect if the chamber is not conical shape, say, a straight cylinder? By saying "enlarging the inner space reduces mid high" does it mean this tuning benefits treble-heavy drivers, and bass-heavy drivers will have even less treble? I'm thinking of another project in the future, not using 130 Ohm Beryllium driver.
Thanks for sharing, my friend.

I didn't post how I build that model. I use Electric Mini Drill for the inner hole and sandpaper to shape the outside. You can find it in a local hardware store probably.
The inner cavity will be cylindrical. On the drawing in the previous post, inner walls follow the shape of outside the wall. This is good only if you have hardwood otherwise the shell will crack. And by hardwood, I mean "stabilized wood".

Could someone verify, whether these 15.4mm drivers (1, 2) are any good for a first 150 Ohm build? I have a feeling they might be the same drivers used in FAAEAL Rosemary.
I might be wrong of course, but if they're good anyway I might as well give them a try. Thanks!

Ask the seller if this is the original HE150ohm. If is not, then probably uses the same driver that you show, but judging by the price I think it's original
I have already talked about this model many times. Sub-bass is remarkable also soundstage

I have Rosemary, and the 19-21 32ohm driver is much better, like 1-2 tiers higher. It's also half the price (of the mentioned 150ohm driver), you can literally buy 2 pairs of 19-21 for the price. Better extension both ways, more details, more dynamic etc. I think subwoof3r had the diy 150ohm drivers and had similar opinion. I'm not sure if the Rosemary's driver is the same as the diy driver though, but it definitely looks extremely similar.

Could you share a link for the said drivers? So far, out of the ones I've tested, these are my favourites. I just wanted to give some 150 Ohm drivers a try, since I never heard them.

It seems they are the ones you shared.

Yeah, I thought as much. If memory serves me well, I think @robar was the one who recommended them. He was right, they're great!

Yep, I was the first one to try this model almost a year ago. Still my favorite, I have 3 builds plus two more planned for the close future.

I post mine 3 experiments with 130ohm Bery but now is your turn with 19-21kHz

Anyone got anything this last 11.11 sale?

I ordered a couple pairs of drivers and another X12 ultra which I plan to convert from earpod/airpod style driver to either the 40Ω Ti or N55 64Ω to see how well it drives it.

Drivers with an impedance around 150ohm are for me personally a sweet spot. Pk1 "red film" 150ohm is the DIY king for now but is rare to find only the driver
Unfortunately, there is not a large selection of these drivers for DIY

I didn't have a chance to use these but it is certain that they were taken from some branded earphones

And as for branded earphones, this is the current situation
- HE150ohm
- YINMAN 150ohm (OG and NEW)
- TY HI-Z F150TS/150S/150 / Balanced / TY HI-Z HP-150
- TONEKING TO180
- FAAEAL Rosemary
- Smabat ST-10s (Gold)
----------------------------------------------------------------------------------------- I will cross the line here
- K's earphone Bell-We
- Astrotec Lyra Collection
- ShoonTH ESEP-01BLE / ShoonTH ESEP-01BU
- SimPhonio Dragon D3
- YUIN OK1 / YUIN PK1

BTW if someone owns one of these, please share your impression

I will share only the photo which will explain everything. This has been going on since March and is mostly for every product

Ouch. Still hasn't come down then.

I see you're planning to build some DIY TWS. Sabbat x12 ultra is a TWS IEM, right?

Yep. DIY earbud TWS.

I've already done it on the older X12 Pro model (non Qualcomm chip). The older model doesn't seem to have near the output of the newer one, so I'm hopeful it will work well with slightly higher impedance drivers (32Ω vs 40Ω or 64Ω)

Also tried my original Yuin PK2 drivers

Wow, I have never seen that variant. Nice work, man. Very interesting concept.
Are you build that 14.8mm part (where goes driver ) over IEM housing?
You need to sell that patent to Smabat to make modular drivers ( Smabat ST - 11 - IEMbuds)
