Wireless Mic recommendations for recording a yoga class?

[Richard Crowley]

There are many sources, models, versions, and colors of microphones like that:

I did not identify the mic in the photo because there are likely at least a dozen options that are virtually indistinguishable.

Note also that those very thin, nearly invisible models are not the favorite of aerobics instructors who move around vigorously. But for more sedate Yoga classes, they would probably be OK.

Recording audio without metering and monitoring is exactly like framing and focusing without looking at the viewfinder.
