Unhappy [Q] How to connect external mic to M7?!

First, I tried this site from eBay:

Didn't work. Didn't even detect it as headphones, let alone mic.

Then I tried this one, which is "trrs," because several HTC phones work with it according to reviews:
Headset Buddy01-PC35-PH35) PC Headset to 3.5mm Smartphone Adapter

Same exact results as the two-dollar wire.

Nothing has worked!

Is so irritating that is so hard to use an external mic with a high-end phone like this.

Can anyone help?!
