That's a really useful correction, and I'll update my thinking based on your first-hand experience.

If you've had both in your hand and you're confident they're effectively the same size and weight,

then I trust that over marketing impressions.

That removes what I thought was the Mini's main ergonomic advantage.

That leaves me comparing them on functionality instead.

Feature.

Mic Mini.

Mic 3.

Wireless microphone.

Internal recording.

32-bit float recording.

Onboard backup recording.

Size.

Same.

Based on your experience.

Same.

Battery.

Similar.

Similar.

If that's an accurate summary, then the Mic 3 is simply the more capable transmitter.

Given your use case, onboard recording is a classic feature.

You don't have to worry about wireless dropouts.

You don't have to carry a receiver.

And your workflow is essentially, open quote, clip on, record, copy.
