Nice Work!
Great Color match to the UEs .
 
Is that a hodvtec with a twfk?

I finished up the UE900 reshell, figured I share some pics:

What is the blue buffing paste you are talking about?  I got some of the multi-colored sanding dremel discs, and I have a cloth buffing wheel on my bench grinder, but I still can't get that glass-like finish you seem to accomplish.  FYI - I found out the hard way that you need to remove the metal protective cover on your bench grinder when using a buffing wheel!  Disaster!

Yes, it's a twfk and a HODVTEC-31618

Cool, that's what it looked like, i have made some in that configuration.

It's a wax compound that comes in a tube, it is specifically for buffing plastic I get it from Harbor Freight. I have had good luck with it. I can tell you there is a break-in period for your buffing wheel. Practice, testing technique, and patience will get you there I promise!

@ Squirg - here is a pic of my buffing arbor:

That is my dream. TWENTY BA drivers per the ear!

They responded to Sonion from, they can send 1-1 pcs of armatures:

$ 2 piece of 28UAP01 price of $ 84.50 and 2 piece of 38AJ007Mi / 8a 60.50 price.
I'm happy because they are precisely the armature will be back to Angie that were in it. Thanks for the help!


Next week the shells come from the lab Microsonics ($ 50 a pair, wood faceplate and blue body) I asked him three pieces of 2mm hole. I will try my earphones Westone UM Pro50 drivers implanted in the shell. One deep (CI 22 995), one dual med and one dual high (both some twfk-swfk from Knowles) go to the three hole. But it is not clear how long to let the tubes (1.8 mm ID), because the high and med in Westone about 12-13 mm long and bass about 20 mm. But Angie was bass about 20-25 mm, mid of about 30-35 mm and high of about 50-55 mm.


Why is there such a difference?

I heard that the Freqphase system can build up ... maybe ...

High frequency travel faster than low frequency. JH audio use different tube length as a method for different frequency to reach your eardrum at the same time.

Regarding the drivers you purchased. The BA may look the same outside but sonion may customize them (internal) according to JH audio's requirement. Bass can be manually adjust from the cable. I believe it contain a variable resistor.

Any pic on the original wiring ? Do note that they maybe wired reverse polarity.

custom knowles bk

As in different driver altogether? Could you replicate the sound by buying a BK driver and the green filter it uses?

don't know

 

[Shilohsjustice]

don't know

You could get pretty close by using a BK – 21669 and a green acoustic damper.

 

[Shilohsjustice]

You would certainly need to play around with acoustic tubing Length.

  And this document shows which drivers are in each diff. manufactures IEM:

Hope these help.  I know they did me!

Fantastic resources, thanks!

Looks promising, TWFK for $10-20 definitely worth it!!! The TWFK was partly taken out of use by major companies due to the cost so this could certainly be another game changer for us DIY'ers!!!
