I do not know what does the color dots mean.
There are 5 variants clockwise (left-top):
  • purple-purple
  • blue-purple
  • orange-blue
  • blue-blue
  • green-blue
Also notice the different minus sign on the purple-purple.
Anybody have a hint about those?

Maybe this answer.

I have sorted the disassebled Nokia HDD-1 drivers.
I do not know what does the color dots mean.

Could just be the paint marker colors given to whoever assembled them.



Edit: Also, I'm jealous of how many of those you have.

And because I have little free time, today I will enjoy my 400 ohm drivers. 😉

Hi! I'm new in diy earbuds. I just want to ask the following:

1. How does the housing help with the tuning? Metal vs wood? More vs less vent holes? Small vs large shell?
2. How does the tuning cotton help? Thicker vs thinner cotton.
3. What's the sound signature of the 600ohm beryllium, 500ohm, and 400 ohm drivers?
4. How does the foam cover help in sound quality? Donut vs full cover
5. Lastly, how long do you burn-in? Do you tune before or after burn in?

Thank you for anyone who would help.

Yes, the Ultimate Question of Life, the Universe, and Everything...
There are some readily available recipes for DIY earbuds, shared in these mighty pages if You are looking for those.
Here You will find many discussions about success and also failure.
If You are willing to learn, there is a good read about how the magic aroung the drivers work, I can recommend, it is very interesting:
A Glimpse Into the Secrets of Headphone Voicing
The same works mostly for earphones too, and this will give You a nice guide regarding many of Your questions.

which drivers have good stage and separation?
will they beat some known prebuilt buds out there in those?
Tell us what prebuilt buds have You tried already, so one can compare.
You know it is not like best car, best phone, best earbud.
It is about You like xxxx earbud, but missing sound stage a bit, or want a bit more comfort, bass, or treble.
If You are unsure, then buy any of the recommended ones and tell us how You like it.
Most of us prefer different shells because of different anatomy.

So it is important to decide:
  • What have You tried?
  • Was it comfortable, too big, too small?
  • What did You liked about it?
  • What didn't You liked about it?
  • What has more/less/wider/fun/ xxxxx than this?
  • Wha t do You listen, on what source? (portable, desktop, HP amp, phone?)
Also please note DIY is not like building a better Ferrari for cheap, it is like building something You like without breaking the bank.

@earfanatic ask right questions. DIY buds can have better technicalities than prebuilt, but not always. When we buy these drivers, we don't know how good these samples are.
Some brands make your own drivers or order them directly from manufacturers and pick only the best samples. Also, you can tune low end, mids and treble. By balancing these 3 you can affect soundstage in some degree, but you need also good DAC and not smartphone or dongles. Imaging is something that you can't change.

Anyway... I'm in the chase of the drivers that have great stage and imaging last couple of years.
My 3D stage KINGs are:
- HE150 or HE150Pro (in MX500 shell)
- Tingo TG-38s
- HiFi Boy Dream (in MX500 shell)
As you can see, you need the right environment where drivers can perform in their full potential. MX500 shell has right design: size, vent system etc. which provide
optimal conditions. As for the fit and comfort, they are not perfect for everyone. Also, there are some examples where driver is tuned to work perfectly with some
specific shell. For example, 150ohm "red film" and DOCOMO shell (Nokia HDD-1) or Foster driver and DP100 shell (ShoonTH buds) etc.

As for the DIY drivers, there are some interesting models. I use mostly high impedance drivers. I will talk about them after you give the answers for @earfanatic Q's :wink:

i see,
so i havent tried any earbuds.
but i like final e2000 tuning wise (slightly less or quicker bass is a welcome so that i could listen to stuff like architects).
would love to try to build somethin with such tuning but with better staging.
i listen to mostly these kinda music:

and metals like architects.
as for the source, i use a laptop with cx31993 dongle.

ShoonTH ESEP-01BL has fast buss and wide stage (stock variant) and precise imaging
120ohm LCP driver has light bass and is also fast.
IMO, LCP only have cleaner mids and highs in comparison with ShoonTH.
All in all, both models are good
