Anyone have any experience with those Countryman mics? Just curious.

Doesn't really apply, but I had a guy stick two in my ears (they were either the tiny Countryman's or Knowles Acoustics) to do personalized HRTF and room response measurements for a headphone virtualization prototype demo a few weeks ago. They looked about the size of tiny sand-fleas buried in the foam earplugs. I didn't get to hear the sound of the mics directly, but the measurement data was spot on and the virtualization system amazing. It corrected for head position (rotation), headphone/pina response and recreated the sound of whatever monitoring system was used to make the initial measurements. So convincing I had to take the phones on and off to convince myself that the phones were turned on and I wasn't listening to the measured monitor system.
The developer mentioned they also used DPA 4060's which had a better dynamic range and lower self noise, but they were harder to fit completely in the earplug and the range of these were 'good enough' for their measurement purposes.
