They are good. IMHO their TWFK and CI is as good as Knowles. Their HODVTEC is not as good as Knowles. They have slightly different characteristics though, you should not treat them as 100% identical plug-in replacements.

Thanks! I might give Bellsing's CI a try, looking to build 2xCI + TWFK.

These drivers get pretty close to Knowles
WBFK
SWFK
Somewhat near to Knowles treble, slightly brittle
So managed to get my hands on some 14mm planar magnetic drivers. The frequency response is provided by the manufacturer. I tested the impedance of the driver too.
Not sure how to use the driver properly due to that massive dip after 2kHz though.
Stuck just the driver near my ear for a quick listen and the mid range is rather clear, which is a good start.
Edit: Ouch, just noticed its -5db at 20kHz!

Well you can modify the driver backwave material, front meat material, can make a edge diffraction correction.So managed to get my hands on some 14mm planar magnetic drivers. The frequency response is provided by the manufacturer. I tested the impedance of the driver too.

Best part is electrical things will remain the same.
First thing, it has to be open back
Second thing, movement of air has to be controlled both side
Third thing, movement of front air has to be captured completely.
i dont think they are on headfi, but they can help you tune planars
one is joppe peelen
second one is Marcus christensen
Joppe makes planar speakers
Marcus makes planar headphone and iem
Out of curiosity, how does one go about obtaining such drivers? It could be fun trying to use those for my next DIY IEM project.
I got them from Toneking directly on Taobao for around US$75. He doesn't list them but I spoke to the seller and they were willing to offer their IEM's drivers separately.

That's amazing, he sold it directly to you
And the price is cool if it is 75$ a pair.
I have tried toneking bl1, amazing soundstage but three weird vents,will make it worse in future(moisture, dust).
Toneking told me he preferred the front sealed and the back open - guess he wanted it really open so he opened 3 vents. He also suggested I use a dynamic driver for the bass frequencies as he also things the bass drops off quite fast.

Can anyone give me an idea how this combination would sound like?: HODVTEC-31618 + SONION 2389 + TWFK-30017 ?

Potentially very good. Potentially very bad. More likely to sound good. What filters, tubing, and dampers are you planning to use? See my point? I don't have suggestions for you there, simply pointing out that it's more than JUST the drivers.

Front sealed.....why will you do that
Where will you get sound from
Well the bass drops as the driver is very small in effective area.
I know this probably isn't recommended but has anyone tried using one of those UV-Resins for printing? Like the Wanhao UV-Resin? 500ml is like 40$ and if you use Lacquer over it, maybe you wont get poisoning? Could be a cheap method to try some new stuff if you don't plan on wearing them hours everyday?
Just for you to know, soundlinks Ali store has Bellsing 6 driver (1x HODVTEC + 2x TWFK) for under $70 per pair in 2 days (anniversary sale)
That’s a steal, even if you just salvage the drivers.
