I purchased the little DJI FM-15 microphone for the Osmo.  For under $6.00 this mic really improves the audio.  It's also small enough to fit inside the Osmo case.  Just an FYI if anyone wants to improve the Osmo audio without spending much.

The Osmo originally didn't come with the Flexi-Mic, it was a later addition to the Osmo and Osmo+ after multiple complaints of voice recording quality of the in-built microphone. The Flexi-Mic now comes standard with Osmo and Osmo+.

FM-15 Flexi Microphone is included in the package at the moment, thank you for the feedback about our product.
Hope you have a great time with it.

I purchased my Osmo a couple of months ago at Besr Buy, but no mic was included.  Good to know that it is now included.
