Suggestions?

I have a client who wants to be able to record her podcasts when she's out of the studio -- using her phone -- via RINGR (third-party podcast service). So, I'm looking for a 3.5 mm TRRS-plug headset with a really good-sounding microphone. Oddly, it's really hard to find any reviews of such things by Googling or Youtubing.

Turning to the wealth of wisdom available here.

Thanks for your insights.
