No need beautiful housing for IEMs
LOL.

I just got these fun little things in the mail today.

TWFK's and HODVTEC's - I'm going to try some different crossover configs.

Nice !  I have a set of these as well waiting for crossover inspiration.  Please let us know what works out best for you.

I can't give technical details on the GV, but I finished building the universal kit from Luke, with bass ports uncovered and the sound is excellent. Sub-bass extends far down, bass is a little above neutral, vocals are clean (but I don't listen to vocal music that much so can't really describe it), no sibilance and high are a little rolled off (could be due to comply tips though)

My first pair with BA. Single driver, BK-28562 from old Shure, with green damper. I`m not happy with sound and fit. Need more accuracy in the processing of the impressions=)
Coming next GK-31732 with red/white dampers. Hope it will sounds and fits better. And looks better =)

If you are able to get Sonion 2389, it will be very good. Basic configuration CI-22955 1.5x2.0 red damper + Sonion 2389 (half coil) 1.5*2.0 green damper. Make 2 sound bores if possible. Results are not bad.

Fitear MH335 DW configuration:
 
2XCI-22955 parallel 10 ohm, orange damper (-) 1.5x2.0
33A007 series full range white damper (+) 1.5x2.0
2389 0.47uF no damper (-) 1.5x2.0
 
anybody want to try this?

Guys, i have a question about measurements.
 
I`m experienced enough with SMAART. I have a soundcard and measurement microphone for acoustic systems. I made few measurements with my earphones, using paper tube mounted on the mic

 And results are far from the truth. But! I have a friend who works in hearing aid clinic and he showed me the measurement system that he uses. Interacoustics Affinity. There is a 2cc coupler with mic. I`m going to connect this mic to my soundcard and SMAART. The problem is that the mic with built-in 3,5 mm mini jack. So, I need to figure out which adapter to do for connecting to my XLR input. In the technical documentation, there is no information about the type of microphone: dynamic, condenser or electret. And pins... I know what to do if i need only pins 1 and 3 (picture 2). But maybe the microphone needs the fantom power. My +48 Volts can damage the mic. Or it`s common balanced connection: 1 - GND, 2 - positive, 3 - negative.  
 
Here is some pics. Any suggestions?

Don't see an easy way to buy Sonion, but will look for it. Thanks for the advice.

ED-29689 works too. Maybe you need 3.3uF on the ED

I installed a drawer on my work bench today!!! What's your workstation look like????

These red/green wires are Estron from Soundlink? How do you tin them? As far as I know, litz wire not so easy to tin.

The best way is to get some solder on your iron tip and place the tip of the wire into it. The solder melts the enamel and tins the end.

Have anyone tried ED-26805 from knowles? i find it quite good to pair with 30095 plus a dynamic. you get excellent sub bass sweet mids and very nice treble extention.

Try to make my first IEM, got CI-22955 and ED-29689 on the way. And I have a on hand ED-30761 and WBFK-30095, can you suggest a crossover for this configuration (CI + ED + WBFK) thanks!

Hey, if anyone is interested in the new Knowles GV, the Mc.Ear Onlineshop sells them for about 80€ here in Germany. I've got mine a few days ago, but unfortunately still could not measure what values the two SMD components have, without desolder them. Is it possible to meassure them incircuit or distort the drivers the measurement?  Now I'm thinking about what Dampers I should use. I think without Dampers the HODVTEC are used fullrange, because only the two FK drivers have a Condensator as higpass. Without dampers the GV have significantly too much heights.
 
Edit: I think, the two SMD components are Resistors. I managed to meassure the left one to 62ohm and the right one to 48ohm. Did that make any sense? I always thought, capacitores in row are used on the high drivers as highpass. But after further measurements i am pretty confident, that on all 4 drivers the negativ side is wired directly parallel and on the positiv side the the  HODVTEC is wired directly and the twfk with the two resistors.
