I have spent a lot of money and time (even developing an iOS app to test that your Mic is working - called MicCheck/MiCheck - free on app store) to try get the set of cables I really wanted. I have sent cables and connectors back and forth to China a few times, and think I have as close as I will get to a perfect solution.
Recap:
I sent Zee/SunRicky a mic control from the UE cable I bought a month or two back, and his replacement cable with this new control just arrived. Physically its exactly what I want:
Small Mic control with volume and control button.
No memory wire- but rather memory sleeving.
Good quality silver cable and jack.
Correct polarity
Total cost is $49 for the UE donor cable and $99 for Zee's cable... and $5 shipping to China.... $153
So far, doing great:
It has been two weeks, and I have to say I am very happy. These cables approach 95% of what I want, and the only issue is that I had to order a UE cable, hack it, and send the control to them. All in all a long time, but the issues with these guys controls is the controls - give em a good one, and it works great.
