Do you know which store has them? All of the stores are out of stock and said that it is discontinued.

Nsc has them

Check out "Onebest Choice" store. That's my go-to shop in Indonesia. Hope that helps.

Hi guys, allow me to introduce the "Head-Fi DIY Earbuds Wiki"
I appreciate so much the wealth of information in this thread, and by creating this list I hope we can organize that somehow. It will certainly help me with my DIY journey, and I humbly hope it will benefit us all, old and new alike.

I'd appreciate your support and contribution to improve this wiki by (in order of preference):
- Quote posts where impressions and tuning recipes can be found
- Post your impressions and tuning recipes in this thread
- Leave comments in my blog
- Send me a PM with any info you have

To keep the spreadsheet easy to read, I will redact the posts. I will do my best but please also keep in mind that we're doing this for fun.
Thank you all!

Has anyone noticed that there are 2 400ohm drivers in nsc store, one for $19 and one for $16....
They both say vocal

Swapped my DIY 16Ω SR2 drivers onto the X12 Pro TWS. Seems to be a better pairing than the ETS 32Ω 'bass' drivers.

Looks wise, went from this:


To this:

(This pic is actually of my Yuin PK2 drivers, but has same style cover as the DIY SR2 16Ω)

Beautiful! Now it's ready for production
First variant with "EBX like" cover looks very nice.

I would put the 500 over the 600ohm, deeper sub bass and slightly better highs

Do you own 500ohm? Their frequency graphs look almost identical

 

[Themilkman46290]

Yep, and from the first listen it was better, I had gotten the 600 first, but decided to try the 500, wish I would have gone for the 500 from the beginning. It's basically what I was hoping for when I bought the 600ohm. If you guys haven't tried them, you should, it is rarely talked about on here but I would rate them in this order
400ohm
130ohm
500ohm
64ohm ti for $16
600ohm
If I had them in the mx500 shells
500ohm
600ohm
64ohm ti $16
130ohm
400ohm

You really like graphene.
For me, graphene has the most balanced frequencies. Period. In most cases, you know what to expect from this driver. Not sure for 68ohm.
From Beryllium I generally expect to be qualitative and dominant in the low end. So far, it has performed very well with the driver size 15.4mm
and probably is the same for 14.8mm 120ohm. Also, I owned a small 8mm Bery. The designer who designed shells didn't think to make a vent in front of the driver so the quantity of the lower frequencies was really overemphasized. I try to fix that and I drill by mistake thought one of the drivers What can I say, "beginner's luck"
Titanium is the only driver that is difficult to predict. 64ohm full Ti (15.4mm) aka. "Chief" has more bass quantity than Graphene and Beryllium.
Bass quality is average and tends to cast a shadow over mids and highs. BTW...mids are not recessed and highs can be called "bright".
But I can't say the same for the little 10mm driver who surprised me quite a bit with his performance. I will compare these two like this (5-star rating)
64ohm full Ti (2.5 / 5 stars) vs 48ohm 10mm Ti (4 / 5 stars).

I find the 120Ω Berylliums borderline too polite in the upper mid-range/lower treble and lacking resolution/detail unless they are provided more power than a typical cellphone output.

You can add these also

32ohms pk1 red film https://www.aliexpress.com/item/32776696327.html

I haven't tried those. How do they compare to the 150Ω redfilm? (I may have asked this before...)

The 19-21 you linked is the recommended "heavy bass" driver, but it's not titanium. The titanium version is this: https://www.aliexpress.com/item/4000741710087.html but please note that this has a special type of mesh cover which doesnt really work with mx500 shells.
I can also recommend this "N50 red rim" for another cheap 32ohm driver (but I prefer the 19-21 overall), and this cover works with every shell I tried: https://www.aliexpress.com/item/33027995148.html

@furyossa

Aren't the 32ohms pk1 red film vocal-oriented?

What about the 150 Ohm 'transparent film'? Have you already tested them?

According to @assassin10000, it seems that the 14.8mm 120Ohm bery drivers have (too) rolled off bass.


@Themilkman46290
Do the 500ohm have a dark sound?

The 19-21 you linked is the recommended... it's not titanium
....

Fixed!
Thank you.
