Thanks for the post, Brian. Even with the upgrade the sound of my voice at 2" sounds like I'm in the next door room with a pillow on my face. I honestly don't think I'll be using the Osmo to capture sound but might use it to sync to sound from my Zoom H5. The FlexiMic gives a much better result than the internal mic. My point was that the upgrade did not address the problem it was meant to.
