Wen is super cheap, compared to Dremel

but found one similar

Ok, so this one has thrown me for a loop, the four driver I've been playing with will has a horrible read on the coupler. In actuality it sounds relatively clean and has suitable bass. The kicker is I've spent all this time and effort and think I created a UE900 clone.

I mean when I have the prototype in one ear and the ue900 in the other they sound identical, I can't really tell the difference at all.

Here is a pic of the protype shelled up. I didn't do any finishing or polishing.

Can I ask why did you use two resistors in series like that?
Just my input, but I've never seen a 68.4 ohm resistor in my life, so I'd suspect that's why.

But 0.4ohm should barely change the sound no? Changing the cable probably will have the same effect.

Not exactly, with the rest of the circuit being wired in parallel, it would have greater effect on the overall impedance of the IEM.

I would think the cable would effect it less than the resistor.
