This is a unique driver for sure. Comfort wise, are they good?

If you look at it closely, it shares almost the same pcb layout as the 6-pack 130ohm Be plated drivers. Interesting.

They are good. 19 -21 red dot are much better

Results from some of my DIY tests:

- 64 Ohm 14.8mm drivers: I don't like them but I don't know exactly why. It is kind they lack (a lot) of clarity. The same happens for the praised 150 Ohm red film set which I had.

These require more damping than they come with to bring clarity or rather to bring up the upper mids & treble.

- 32 Ohm red film 14.8mm drivers: better overall sound rendering than the 150 ones, but still lack bass response (bass light);

I haven't tried these. May skip them if they are that bass light. Plus I have my 150Ω red films to keep me happy.

Just wanted to ask, does MMCX modding a long DoCoMo impact it's sound in anyway? I thought taking the stress relief and slightly opening up a gap that's usually covered on the side might change the sound a little but I just want to double check. I was considering doing an MMCX mod for my friend but kept thinking it might be better if I just re-cable.

When I bought the TRN BT20s Pro for my earbuds. I found that they can't fit my ears when plugging with my stemless earbuds.
So I draw and printed some shells with stem and they fit really well.

3D printed with PLA

using MMCX.

Yes they fit, and they fit even better than using with cables.

Woah, that's freaking cool! First time seeing a 3D printed shell build here. I honestly wanna invest on a resin printer and do some earbud/IEM shells but maybe in the future

- 24 Ohm double unit 15.4mm drivers: It seems that they have "2 speakers ?" per side. It is very interesting.

ClieOS has used those drivers in a DIY MMCX build that were tuned to his preferences, from what I know about them you have to take their faceplate off and cram them into an MX500 shell and faceplate if you want a similar result to ClieOS' build. Overall, very interested to see if anyone in this thread manages to do a MX760 shell (which I'd imagine would be easier) or even MX500 shell build with this driver.

Used Nokia HDD-1 arrived. Thank You all for the recommendation.

My investment (~$3) will be turned into a great earbud.

I had hard time opening buds before. But hey, I didn't know we have an earbud opener tool in the kitchen drawer.

No joking, it did the job nicely!

Red film driver shining through:

Seems genuine, measures 143Ohm.

Yeah, the glue on these buds can be a pain in the ass, might have to try this out on my other pair of stock HDD-1's since I had issues opening up my first pair. Hope you enjoy your pair though .

This is great.

it was a popular driver years ago..
i have build two pairs of them into mx760 shells in a regular way. its not easy to fit into mx500 shell if i remember correctly.
it's sound character is very close to 130 ohm beryllium without tuning but 130 ohm is better in almost every aspect for me.
but i didn't bother much about tuning and have no idea about its potential..
and i should say that, it's not average diy job, very sensitive to de/soldering and it's soldering points are much smaller than most drivers.

@vygas @endia

Thank you.

I will thus skip them because I already have the 130 Ohm beryllium drivers.

@assassin10000

These are my 64 Ohm drivers. It seems they are the same as yours.

I had to remove the original damping material otherwise they wouldn't fit my 14.8mm shells.
