Hi all!
I will start by apoligizinf for my English - I am from Denmark.

Now that that's out of the way we can get down to the fun stuff :D

I've decided to build my own CIEM's.
Why you may ask? (It's now that you should ask it)
A: Well my PFE 122's were stolen so I had to get something else.
I looked around and had a hard time finding anything - and being in Denmark it can be REALLY hard to listen to a pair of IEM's let alone just regular headphones.
Originally I settled on getting the Music One's from The Custom Art. 
Then I read about them, and their big brother, Music Two's, and figured - why don't I just build it my self?
The Music Two's use the 1723WT03/09 as a driver and I quickly calculated that I could build one my self with parts to spare afterwards for quite a bit less than that.
Not shaming the Music Two's here, they seem to be at a good value compared to other.
 
So I went on the adventure of sourcing parts for this project - again not easy when in Denmark.
But finally found it all and I will be building at least one pair of CIEM's using the 1723's - perhaps even a quad with two of them? Who knows time will tell.
So today I got most of the parts and started tinkering:

But the result sucked!
Then I tried trimming the heatshrink tubing down to see if that was the culprit but to no avail.
So I started trimming the clear tubing. 
It moved it closer to being good.
Then I trimmed it a lot!

And there it was - I could finally sense what this driver was capable of.
It is still not there yet - but I think it will be once I have made a stepped tube for it to act as a horn in accordance to Sonion's guide.
It have, though, revealed that all my audio sources sucks big time - so perhaps I should get an amp/dac soon.
 
More to come! I will be making my own shells of UV cured acrylic and test with different dampers, and perhaps a quad.
Maybe if the 1723TW03/09 has too much bass I will do a quad with one 1723WT03 + 1723WT03/09

Hi mikkelmmk93,
 
Where did you locate and purchase your Sonion 1723 drivers? I'd really be interested in snagging a couple (or a few :D ) to play with and test. Thanks!
